Letshuoer (Shuoer) - S12 Ultra

For me it’s a mix of the feel of the build quality along with generally higher resolution and better separation of instruments as you go up in price (to a point). Other than that tuning is largely the difference and you could easily prefer a $300 IEM with your tuning style to a $1000 one with a different signature. I just got the s12 ultra used for $120 and compared it to my $1000 monarch mk4 and honestly it’s tough to justify keeping the monarch. The resolution and separation on the s12 are pretty impressive, the bass hits more to my liking as well… then I compared to my old apple ear buds and there is a clear difference in resolution even though to me the apple buds still sound pretty dang good. Other ppl will have better explanations I’m sure and it’s debatable what resolution means to people in this hobby. Either way In today’s market, $50-300 can get you some incredible sounding IEMs

S12's are one of my favorites.. but once you get the S15's its all over.

From a business standpoint of view, Letshuoer is pandering to the larger market. The original S12 was a unique release that pleased many trebleheads. But knowing that the market is filled with bass-heavy sets (as demanded by the market), Letshuoer must stay competitive by releasing their own sets to compete with the bass-hungry options, or die out. Which each iteration of the S12, the treble that made the S12 famous is continuously scaled back, with it's bass cranked up. I personally own the S12 Pro. At the time, I demo'd the S12 OG and 2024 edition. OG was too shrilling for my liking, and the 2024 edition was too expensive for a slightly warmer version of the S12 Pro. It seems that the Ultra is an even warmer version of the 2024. Will Letshuoer release a S12 Max next year that are planar bass cannons? I agree with u/The_Only_Egg, Letshuoer has definitely milked the shit out of the S12. I doubt the S12 Ultra will be able to relive the (short-lived) glory days of the S12 OG and S12 Pro. 2024 and Ultra are such far deviations of the S12 OG and Pro that Letshuoer should just come up with a completely different SKU for the Ultra.

Unfortunately I missed out on the 2024 edition and didn't really want to pay for their markup, so these were a welcome release. I received mine a few days ago and wow what a difference from the OGs! The originals had a bit too much edge on some tracks, but the ultras glide through anything I've thrown at them so far. Sometimes I miss the extra zing in orchestral or edm but overall prefer the more comfortable and versatile experience of the ultra. The included dongle was alright, but I did end up swapping to the jm20 max for more volume headroom. The quality of the cable, modular connections etc all feel really good and I'm very happy with it for the price.

[Full Comparison/Review](https://youtu.be/B1DqoqBSsqQ) ***vs OG S12/PRO/2024, SUPERMIX4, DEFIANT*** S12 ULTRA Ranked: [JAY's IEM Ranking List](https://docs.google.com/spreadsheets/d/1ZHVib50XFQW4up3SwOZUTbI-hZB6Ir5LX6XnZblIM6o/edit?usp=sharing) S12 ULTRA Graphed [Here](https://jaysaudio.github.io/index.html?share=Harman_2019,S12_ULTRA) \--- **OVERALL SOUND:** Dynamic, sub-bass focused, smooth with a slight treble emphasis. Slight v-shape. * The smoothest S12 letshuoer have made so far * Bass is rumbly and deep with a satisfying impact and slam, full, bassy, but quick enough to not mud the mids * Vocals aren't buried and pop out enough in the mix - although 1.5K peak might be a bit sudden and sharp on tracks with less low-end in the mix to cover the peak. As long as you're not blasting these you won't have an issue with any vocal shout, but you might run into some on tracks with no bass * Treble is well-extended and has the S12 airy house sound to them but without being overly sharp and bright due to the uppermids cut, and 8-15K treble dip * Enough transients for a contrasty and fun sound, but smooth enough to not be fatiguing * The bassiest and least energetic out of all the S12s - feels the most refined **Volume Scaling/Genre Rec:** * Recommend listening volume is around 65-70dbs with R&B, rock, pop, indie, acoustics, classical * Can be fatiguing on more energetic POP/KPOP/JPOP (turn down to 60dbs) due to the vocal peak at 1.5K + the treble * Mid-volume set **Technical Performance:** * Competitive, but not price leading or punching above its value * Good transients, imaging, bass texture, and treble detail * Less detailed vs OG S12, SUPERMIX4 - around the same as S12 2024 and SIMGOT EG280 **Build & Fit:** * Average size, slightly shallow fit, same size as other S12 iems * I have average size ears and found it a bit shallow - had to step up a size in tips but aside from that pretty comfy overall (use wide tips) * Around 5.8mm nozzle size including outer ring **Accessories & Packaging (see 3rd pic):** * "Mocha" matte metal finish with color matching brown/silver cable * Comes with interchangeable 3.5/4.4mm, and black round case (screwing it on is a bit annoying since you have to line it up perfectly, but it's light, compact, and sturdy) * x1 set of regular white silicone tips, and x1 set of black wider silicone tips * Solid unboxing/accessories at its price, no complaints **Final Ranking & Recommendation:** Mid-volume (65-70 dbs) * Tonality: 7-7.5/10 * Tech: 6-6.5/10 * Overall: 6.5/10 **RECOMMENDED (don't crank these)** The S12 Ultra is fun, dynamic, bassy with enough air and transients to hold up in the technical department. If you found the previous S12s or planars to be too bright and energetic, then the Ultras might just change your perception this time around since - I guess you could say - it has a more "musical" approach to planars. Even though value wise the S12 Ultra isn't going to outcompete some cheaper planars like the ARTTI T10, NICEHCK F1 PRO, or KEFINE KLANAR, or even its younger brother the S12/PRO - it is however more musical, dynamic, but also smoother and more refined in the playback... So for those who aren't chasing insane details - the S12 Ultra is one of the few planars that I actually enjoy listening to outside of solely for reviewing (but just don't blast these).

s12 not for detail lovers? idk if s12 ultra is very different, but from my impressions, my s12 can easily compete in technicalities and details with sets x4 its price

Planars for me are like cheaper equivalent of good multi-driver IEMs. What I like though about most cheap but good planars S12 series. Timeless series Hidizs MP145, 143 Simgot ET142 etc IEMs is that they sound 'transparent' like even when there is a lot of sounds playing at once I can still clearly hear everything like for example I was listening to a podcast while this orchestral rock music with so many instruments playing yet I can still clearly understand what is being talked about on the podcast.

It is more of a tuning thing really. The S12 Ultra sounds meatier vs my MP1145 which I liked better because my MP145 sounds kinda thin in my opinion.

Best in general including the 2024. It sounded slightly more refined than the 2024 edition. They also went back to using the old style shell. It might be even better titanium, I vaguely remember the guy saying that.

Pretty damn smooth and no weird peaks. Pure planar magic.

Smooth and a lot more refined overall. Was not bothersome in those regions like the older ones.

After using the S12 ultra for a few hours, here's what I like and dislike so far: Likes: -Has that lite V shape sound signature and none of that weird & unnatural planar timbre, sounds very DD. -Small and comfy, great to listen/game for long hours. Build quality is great. -Got decent amount of accessories such as: a silica gel packet, 2 sets of ear tips, 3.5mm USB-C DAC, a modular cable and a compact case. Packaging is simple and compact. -The overall sound is warm, natural, smooth and musical with some sparkle. -Bass is speedy and clean. It has good rumble, punch and slam although it's a bit subbass focused. -Mids are balanced and neutral yet the vocals doesn't sound lean or lifeless. Sounds enjoyable on both male and female vocals. -Treble is well extended, decently detailed and occasionally sparkly without sibilance/fatigue. -Scales well with volume and sounds well balanced, no harshness or any other red flags. -Soundstage is a bit on the intimate side but still able to discern height, width and depth at a decent level. The same goes for imaging and layering. Dislikes: -Accessories could be better such as providing a cleaning brush, cloth and a wider case -Sounds unforgiving with poorly mastered tracks, so ymmv depending on your playlist. -Bass texture could be better and needs some more midbass quantity for that extra meatiness. -Not for those who want to analyze/dissect music. The s12 ultra is meant for those that enjoy music without thought. Not for treble heads/detail lovers either. -Soundstage, layering and imaging could be better especially for a planar driver. But the difference in tuning philosophy leads to a compromise TL;DR: I rate the S12 Ultra an 8.5/10. It's a competent, smooth & all-rounder planar IEM sounding like a good DD. Best to get it on sale imo (I got it down from $169 to $126 from Shopee).

This is my first ever Letshuoer IEM and I talked to some folks that tried the s12 ultra and the previous models. To them it's a side grade. And given how smooth the s12 ultra sounds on the FR graph (2nd slide), the details aren't as pronounced as it should be especially for a planar driver. Letshuoer had 4 versions: s12, s12 pro, s12 2024 and now s12 ultra. also, they explained the differences in their marketing material. to me the s12 ultra sounds like a smooth warm DD EDIT: Letshuoer had 5 versions: s12, z12, s12 pro, s12 2024 and now the ultra.

yea, it seems like it especially after the positive reception of the 2024 model. I'm glad my unit sounded great ootb especially for a planar IEM. they did a solid job making it sound like a DD without the drawbacks except that planars are still power hungry lol.

Simgot et142 is also pretty good. Look up on audio amigo's review of the et142, I agree with his take. Thwt IEM is a great chameleon and he compared it to the s12 ultra in the s12 ultra review. I compared it with the s12 ultra as well and I prefer the et142 more. Bass is punchier and vocals are more forward with the black nozzles without the shoutyness and fatigue. Also, the et142 is more sparkly than the s12 ultra. The s12 ultra sounded a bit too smooth for my liking.

4.5⭐️ + A slightly smoother and more relaxed variation on the S12 tuning + A welcome sub-bass boost + Natural and well-balanced midrange + Treble energy and incisiveness takes a step back this time around + Same great build quality with a slightly refined shell design + Nice accessories including a modular cable and USB-C dongle - Extra bass emphasis might be a bit too much for some - Treble may be too understated for those seeking a more traditional planar sound - Trades a little in the way of technical performance for more musicality; separation could be better - Potential QC issues with 2-pin connectors thaslaya's star rating system: ☆☆☆☆☆ - Fantastic! ☆☆☆☆ - Recommended ☆☆☆ - There are buyers but not for me ☆☆ - Can't see the appeal ☆ - Product is a failure Disclaimer: This product was provided to me by Letshuoer in exchange for my impartial and honest review.

Introduction: Letshuoer is a Chinese IEM manufacturer that should be well-recognized by most audiophile enthusiasts. They produce many well-regarded IEMs in different price ranges, as well as offering a portable DAC amp as well. Their S12 line is arguably their most popular product to date and it includes three previous models: the original S12, the S12 Pro, and the 8th-anniversary S12 2024 edition. This new Ultra model, priced at $169, is the fourth and final iteration of the S12 line, and it features the same single 14.8mm planar driver as previous models. Let's break down the new Ultra and see if Letshuoer has indeed saved the best for last. Build, fit, ergonomics: The Ultra comes in a smallish, somewhat inconspicuous but still nice-looking black box featuring a shiny geometric pattern on the front. The unboxing experience is a little underwhelming but still consistent with others I've seen in the sub-$200 price range. All the necessities are there, but considering the fantastic packaging of the S12 2024 edition, the presentation could be better. The Ultra maintains a very similar design and aesthetic to others in the S12 line. The shells are made of an aluminum alloy and feel lightweight yet sturdy. The Ultra is available in two colors: gunmetal gray and mocha. I opted for the mocha, and I really like the rich brown/copper tone. Also, the matte finish helps to ensure that it's not too prone to showing fingerprints and scratches. Even if it's almost the same, the Ultra has received a few design tweaks this time around, most notably on the little rectangular piece that adorns the faceplate. It has a slight three-dimensional effect that, while subtle, helps to elevate the look of this new model just a bit. The fit is similar to others in the S12 line as well, but I did find it a little easier to acquire a deeper insertion, though I would still welcome a longer nozzle. The Ultra has a vent located by the flat 2-pin connection like previous models, but it does look to be slightly bigger this time. Speaking of the 2-pin connection, I ran into a small issue when trying to cable roll. The right shell has a very tight connection. It took some patience to get the stock cable inserted and even more effort to remove it. When I went to try another cable, one of the pins nearly bent while exerting the necessary force to get it to seat inside the housing. After that I chose to put the stock cable back on and only utilize it for the review in fear of damaging my other cables or the IEM itself. Now, this could just be an issue with my unit, or perhaps it's potentially a broader QC issue, but only time will tell as others start to receive their own units. Back to the stock cable, this one is a four wire silver-plated copper cable, and it includes both 3.5mm and 4.4mm interchangeable terminations. It's soft and lightweight with a nice weave and an attractive brown and silver two-tone design that's very complementary to either shell color. It also has some nice mocha-colored hardware accents that will admittedly look much better paired with the mocha shell. The modular termination system utilizes a screw-on locking mechanism to keep the terminations securely in place, which I appreciate. There are six pairs of tips included in the box: three of the black vocal tips and three of the clear balanced variety. I personally found the Ultra to be quite tip sensitive, and those with a more rigid core worked best for me. I tried a wide variety of tips from my collection, but I finally ended up back with the stock balanced tips. The case is the same typical plastic puck-style case that Letshuoer includes with some of their other more budget-friendly sets like the S08 and newer D02. It functions fine but does feel a little cheap at this price. The only other accessories of note are a Velcro cable tie and a USB-C dongle DAC, which makes the Ultra easy to plug and play right out of the box. Overall, the accessories are decent and about what I expected from Letshuoer. The modular cable is great, and the inclusion of the dongle DAC is a nice surprise, but the case could be of better quality. Sound impressions: The S12 Ultra has a V-shaped tuning, but it's done in an impressively balanced way, as no one frequency manages to steal attention from the others, though admittedly I find the midrange to be ever so slightly recessed for my preferences. As for drivability, planar IEMs are somewhat notorious for being power hungry, and the Ultra is no exception. The included USB-C dongle is capable of reaching high volumes, but it did require about 80% volume on my phone. I much prefer to use the Ultra paired with an amp via the balanced 4.4 termination, which I'll touch on in the next paragraph. The note weight overall is good. The upper mids and treble can get a touch thin on certain notes, but the heftier bass can help balance it to a certain degree. The detail retrieval is actually a little sneaky. I never feel like I'm missing out on the nuances or subtleties of a track, but the Ultra definitely doesn't force details upon you like so many other planars I've heard. I appreciate the way it lays things out for you to discover for yourself. The stage is not particularly expansive or grandiose, but it still has very nice width and depth and makes great use of the space to portray a spherical and uniform presentation. The timbre is quite natural and organic and one of the standout features of this set for me. The imaging is also impressive, as it's very strong both left to right and with distance. Unfortunately, the dynamics do fall a little flat. I think the Ultra is definitely a set made for medium and higher volume listening, as it takes some decibels to wake up and reach it's full potential. While the layering is good and helps present a nice, cohesive sound, unfortunately, the separation struggles a bit, and the Ultra can get slightly bogged down by complex tracks. This is a bit of a letdown for me, considering most planars I've heard typically have great separation. I don't think this one is too far behind, but it doesn't manage to impress the same way other sets do. Overall, the Ultra isn't quite the uber-detailed, technical powerhouse that I have come to expect from my experience with planars. In this case, it leans a bit more heavily on musicality, and even though it falters slightly in a few areas, I actually enjoy this deviation from the expected. The Ultra is not overly source sensitive, but taking time to find the right synergy can be beneficial. The GO link Max has a V-shaped profile, and that's apparent when paired with the Ultra. The midrange gets a bit scooped, and there is more energy in the bass and treble, though it's not my ideal sound. The Questyle M18i pushes the boundaries of bass texture and resolution, but it loses a touch of low-end quantity and impact. This might be a choice pairing for those looking for absolute performance and technical ability. The iFi hip dac 3 is a warmer source, and the Ultra definitely benefits from this pairing by taking some of the zing and bite out of the treble, but that is also one of the things that gives the Ultra that unique planar character. Personally, my favorite source synergy is with the DUNU DTC480. This little dongle packs plenty of power and it helps bring out the fullness in the bass as well as a slight midrange emphasis. ●Lows - While the Ultra's bass is definitely elevated, it's not overbearing. In fact, it's actually quite well-balanced with the mids and treble. The low end is a bit more sub-bass focused, and the extension is quite good. There's also a nice level of rumble and reverberation, though it's not really a sustained type of presentation, as the decay is on the quicker side. The mid-bass does have a decent impact and slam, but I think it could still use a bit more presence to better balance out the sub-bass. The Ultra's capable planar driver still adheres to some of the more common characteristics of this type. The texture is clean, speed is quick, and the resolving nature ensures details aren't left behind. There's also no bass bleed into the midrange to worry about, which is always a plus. Overall, the Ultra's bass won't knock your socks off, but it is tastefully elevated and well-balanced, with nice technical performance to boot. The sub-bass extension is a great addition, though I feel the mid-bass could be a little more impactful, and the slightly quicker decay could last a touch longer for my preferences. ●Mids - To my ears, the midrange of the Ultra is definitely the smoothest and most musical of the S12 line that I've heard. The overall balance is still on point, but vocals are just a touch pulled back this time around. Both male and female artists are equally well represented, and there's also a level of musicality and soulfulness that the other models didn't quite capture. Vocals are far from being shouty, though I will admit they aren't quite as engaging as I had hoped, though the Ultra seems purpose-driven to provide more of a relaxed tuning than previous models. The included vocal tips definitely work as intended and they can push the upper midrange more forward, but they also sacrifice some bass presence in the process, which I didn't particularly like. The midrange timbre is quite natural for vocals and instruments alike, and lower-register instruments are well represented. In fact, the balance across the midrange for instruments is fantastic. In orchestral arrangements, cellos and lower brass mix together very well with things like violins and upper woodwinds, and I never feel like they have to compete against each other for my attention. Overall, I think the Ultra's midrange is another strong aspect of its tuning. The slightly smoother, more relaxed, and more emotive vocal presentation is complemented well by the natural instrumental presentation, but those who prefer a higher level of upper midrange energy and engagement might find this one a bit underwhelming. ●Highs - The treble is probably the most interesting part of the Ultra's tuning for me, as that telltale planar sheen and zing of the past S12 models has now been resolved. That's not to say the treble here is particularly dark or lacking, but the crispness is noticeably toned down, and it's less incisive or sharp than many other planars I've tried. For me and my preferences, that equates to a much more enjoyable experience, but the Ultra still manages to maintain a nice level of detail and clarity that I've come to expect from previous iterations. Admittedly, the treble can still exhibit a little bite on certain notes, mostly sibilant-prone ones at higher volume levels, but generally it's a smoother affair this go around. The upper end extension is admirable, and the level of air, while not huge, presents a nice counterpoint to the elevated sub-bass. Cymbals are energetic without being overly splashy, and snares and claps are crisp without sounding harsh. Overall, the Ultra's treble is easily the darkest sounding of all the S12 models, but I wouldn't necessarily call it dark in general. To my ear, it sounds like Letshuoer dialed this one in just right by bringing the energy level down a notch, and I'm glad the planar sheen was left on the cutting room floor. That being said, those looking for a more traditional, energetic planar treble may have better luck with one of the other models in the S12 line. Comparisons: ● AFUL Performer 5+2 ($240) - This is an interesting comparison between the Ultra's full range single planar driver against the 5+2's 2DD, 4BA, 1 microplanar tribrid configuration. I'd say both sets have pretty comparable accessories. The Ultra's modular cable is definitely a plus, but the 5+2 does have a quality stock cable too. The performer also includes more tip options and a sturdier metal case. When it comes to build quality and design, though, these two are quite different. The Ultra is smalller in size with a sturdier metal shell that's consistent with prior S12 models, while the 5+2 has a larger full resin build. Surprisingly, though, despite the different materials, they are quite similar in weight. When it comes to fit, the 5+2 has a semi-custom contoured shell and a deeper insertion that I prefer, though the Ultra is still comfortable too. The Ultra's sleek design and mocha color scheme are more understated compared to the bolder green faceplate of the 5+2, but I personally prefer the latter. As for the tuning, these two graph pretty similarly, but the Ultra is a bit more V-shaped while the 5+2 is a little flatter and more U-shaped. In the bass, the Ultra has the advantage in sub-bass extension and overall quantity. The rumble and punch are also noticeably more robust than the 5+2, whose bass is more linear and even-keeled. I generally prefer more bass quantity, but the Ultra's added emphasis can draw attention away from the lower mids, which have more presence on the 5+2. Speaking of midrange, the Ultra's vocals are slightly warmer, a bit smoother and a touch recessed, whereas the 5+2 is more forward and engaging, and it really allows them to shine without completely taking the spotlight off the other frequencies in the process. It definitely has what I consider to be the superior overall balance of frequencies to my ear, though those looking for a more relaxed midrange presentation will likely prefer the Ultra. In the treble, the 5+2 is slightly more lively and energetic with a bit more air and sparkle, but it can also make cymbals sound a little too splashy. Neither set has any real sibilance or harshness to speak of, though the 5+2 can be somewhat incisive with a little extra bite at times. When it comes to technical performance, the Ultra has better layering and timbre, a wider soundstage, and slightly more detail retrieval, while the 5+2 has better dynamics, separation, and a bit more note weight. For me, this matchup ultimately comes down to personal preference for bass and midrange presence. These two actually sound much more different than the graph might lead you to believe. The Ultra undoubtedly has a bassier and more V-shaped presentation, which means the midrange takes a bit of a hit, but it's also the smoother-sounding of the two with an emphasis on musicality. The 5+2 has a slightly better overall balance to my ear and a certain engagement factor that really draws me in, though I do wish the bass extension was better. Honestly, I think both really deserve a place in my rotation, but if forced to choose just one, I'd have to go with the 5+2. The Ultra is the easier set to let music play in the background without becoming too much of a distraction, but if midrange engagement is important to you, the 5+2 is the clear choice. My pick: 5+2 ● Letshuoer S12 2024 ($200) - Here's arguably my most anticipated comparison, pitting my favorite planar to date, the S12 2024 edition, against its newest sibling, the Ultra. Both sport the same 14.8mm planar driver but have slightly different tunings. As far as accessories go, the 2024 edition has a better unboxing experience, but the cable and cases are nearly identical. The 2024 has some extra goodies like the keychain, metal spinner, and a few extra tip options, but both include the same puck-style case and nice modular cables (though the 2024 also has a 2.5mm termination along with the 3.5mm and 4.4mm). The metal build qualities of the shells are also comparable, but the 2024 is heavier, and the shiny gold color is more eye-catching, though it's also more prone to fingerprints and scratches. These two models are nearly the exact same shape and size, but the Ultra's faceplate has a slightly different angle to it, including the small rectangular shape where the 2-pin connection is housed. These look to be completely cosmetic changes, though, and the fit is the same. The vent on the Ultra does appear to be slightly larger, but I'm not sure it's enough to make a difference. These two really do have very similar tunings, but there are a few small differences that might make you prefer one over the other. Both have a very nicely balanced V-shaped sound signature, though the 2024 is a little more energetic and upbeat, while the Ultra is more laid-back in its presentation. Looking at the graph, the Ultra measures with a large sub-bass boost and further extension, but in-ear, the difference isn't as big as the graph would lead you to believe. The 2024 has a bit more mid-bass punch, while the Ultra has more sub-bass rumble, fullness, and better extension, as well as a slightly cleaner texture. However, when you perform a direct AB comparison, I think the Ultra's bass boost mostly results in skewing the overall frequency balance a bit away from the treble, which in turn leads to the aforementioned less energetic sound signature. The Ultra's midrange similarly benefits from the bass boost in that it adds a touch more weight to male vocals and less emphasis on females in the upper midrange. The 2024 version pushes vocals a bit more forward and adds an injection of energy and crispness that demands more attention. I think the treble is where I hear the most difference. The 2024 has more of that innate planar twinge and zinginess this driver type is known for. The Ultra still offers a similar level of extension and detail, but a bit of the sparkle is dulled, which can make a huge impact with some troublesome tracks, at least for me. This is somewhat of a double-edged sword, though, because the treble energy and brilliance of the 2024 is part of what makes it special, though treble-sensitive people will likely appreciate the Ultra more. As for the technical performance, the difference is subtle, but the 2024 has better detail retrieval and separation, while the Ultra has a slightly more natural timbre and better layering. Ultimately, this matchup really comes down to personal preference. The tunings are very similar, but the 2024 presents as more energetic, detailed, and resolving. It puts more eggs in the treble and technical performance baskets, if you will, while the Ultra opts to favor a smoother and more musical presentation. Picking between the two is quite difficult for me, and I think my choice could change depending on my mood. Sometimes I want to mellow out, and the Ultra is perfect for that, while other times I want a more upbeat and energetic listening session, which favors the 2024. My pick: Tie Kiwi Ears Aether ($170) - Here we have another single planar matchup, and these two are actually priced the same. Regarding the accessories, the Ultra has a better-feeling modular cable, but the Aether has more tips, and I do prefer its zippered case to the puck-style case of the Ultra. Build quality-wise, these two are pretty different. The Aether's resin shell is much larger, and it has a deeper insertion that I like, but the Ultra's metal shell is sturdier and just as lightweight. I also prefer the simpler and sleeker look of the Ultra. Both offer a comfortable fit for me, but the Ultra will likely be better for those with small ears. When it comes to sound, these two have a very similar V-shaped tuning target, but when comparing them directly, their differences become more recognizable. In the bass, these two sound very similar, and both have some of the characteristics of planar bass that I really appreciate, including a clean texture and nice resolution. The Ultra, though, has more sub-bass quantity and better extension, as well as a little extra rumble. The Aether's bass is a little better balanced between sub- and mid-bass, and the mid-bass punch is a bit more impactful. The midrange also reveals a few more differences. Vocals on the Aether are a bit more pronounced and pushed slightly forward in the mix compared to the Ultra's smoother and more mellow approach. But while the Aether is a bit more engaging, the Ultra has the superior timbre and overall balance between the lower and upper mids to my ear. To my ears, the treble is where the biggest difference lies. The Aether has a certain edginess and slight harshness on some notes that the Ultra simply doesn't fall victim to. That means that the Ultra is definitely the better choice for treble-sensitive folks like myself, though the Aether isn't a huge offender of treble harshness, so it really depends on personal tolerances. Both have really nice detail, but the Aether does have more crisp and concise notes, though, interestingly enough, the Ultra has a little better extension and air. As for the technical performance, these two trade blows quite well. The Aether takes a slight edge in dynamics and separation, while the Ultra has better timbre and layering. For me, this one comes down to tuning execution. I think the Aether has a bit of an identity crisis going on in that it doesn't quite know what it wants to be. Its tuning takes more of a middle-ground approach between technicalities and musicality, whereas the Ultra leans more heavily into the musicality aspect, which I appreciate. That's not to say it has worse technicalities, though, as these two compete well. I simply mean that, to my ear, the Aether's tuning sounds a little unsure of itself, whereas the Ultra knows it wants to exude a very smooth, musical, and somewhat relaxed tuning, and it executes it very well. In fairness, the Aether does have a bit more of that traditional planar sound in the upper frequencies that some may prefer, and it's a touch more engaging to boot, though I still prefer the S12 2024 edition for that particular type of sound. My pick: Ultra ● Hidizs MP143 ($110) - Here we have another single planar matchup, but the Ultra utilizes a slightly larger 14.8 mm driver compared to Hidizs' 14.3 mm. The 143 also includes three different sets of tuning nozzles, and for this comparison I'll be using the gold nozzle since it measures the closest to the Ultra. When it comes to the accessories, the Ultra comes with a nicer modular cable and a much sturdier case compared to the 143's leather pouch option. Both have a similar amount of tips, but the 143 does have the aforementioned tuning nozzles, which add a good amount of versatility. As for the build quality, both have sturdy metal shells, but the 143 is much larger. It also has an interesting lined pattern on the faceplate that draws my attention, while the Ultra's design is more conservative and minimalistic. Both sets offer a similar insertion depth and fit comfortably for me, but the Ultra's smaller form factor will undoubtedly offer a better fit for the majority of people. Regarding the tuning, these two aren't too far apart, but they do have some key differences. The 143 is more U-shaped with added warmth and engagement, while the Ultra is more V-shaped yet better balanced to my ear. In the bass, as far as quantity goes, I think these two are pretty comparable, but they do things a little differently. The Ultra is more sub-bass focused with better extension and superior rumble, though the 143 is no slouch either. The 143's bass is a little quicker and bouncier with more mid-bass quantity, punch, and a level of warmth that I like. However, it also has a quicker, less natural-sounding decay, and the resolution and texture aren't quite on par with that of the Ultra. The midrange is where things really get interesting. Looking at the graph, you might think these two sound very similar or maybe that the Ultra would be a bit more forward in the mids, but actually the opposite is true. The 143 pushes vocals further forward, but they are a little thinner sounding, too. The Ultra does a better job at preserving an ideal balance across the frequency response, and vocals are positioned just about right for me, if not a little less energetic, engaging, or emotive as on the 143. When it comes to the treble, these two are actually quite similar. Neither one really outdoes the other in energy or extension, but the Ultra lacks some of the incisiveness and bite of the 143, which I consider to be a nice evolution of planar treble. On the other hand, the 143 has more of that traditional planar zing that some seek out, which can sound a little sharp and thin at times. It's also more prone to sibilance, whereas the Ultra is much better controlled. As for the technical performance, both have quite a solid foundation and compete well, but the Ultra does eke out a small victory in many categories, notably in imaging, detail retrieval, timbre, and layering. For me, this matchup comes down to the overall tuning balance and sonic preference. When switching back and forth between these two, the Ultra simply sounds more cohesive and agreeable, while the 143 took a minute or two for my brain to adjust. The gold nozzle of the 143 offers a more colored sound thanks to the added mid-bass, and vocals are more engaging, yet they can sound a little artificial, and some harshness sets in at higher volumes. It also has a touch of that definitive planar sharpness and zing in the upper frequencies, which the Ultra mostly solves. While the 143 obviously offers greater versatility thanks to the three sets of tuning nozzles, the Ultra has better accessories, improved technical performance, a smoother treble, and a more enjoyable overall balance to my ears. I personally think the Ultra is well worth the extra $60, but I really can't fault anyone for choosing the 143, especially those seeking a bit more of that classic planar sound. My pick: Ultra In conclusion: I really wasn't expecting Letshuoer to release yet another model in their S12 line after their fantastic 8th-anniversary 2024 special edition, but I'm really glad that they did! The Ultra is slated to be the last S12 iteration, and it seems like the company took a lot of the feedback and criticism of previous models to heart in their final tuning of this 14.8mm planar driver. The Ultra is a smoother and more musical affair, but it's not without its fair share of detail and technical prowess. The sub-bass boost is a welcome addition, as well as the more emotive vocals and the slightly darker treble response. The great accessories and competitive pricing are really just cherries on top. The Ultra is a great mixture of musicality and technicality and makes for an easy recommendation for anyone looking for an introduction to the world of planar IEMs but wants to avoid some of the brighter and more zingy options out there. Of all the planars I've heard, it might also be the best all-rounder, as it's able to seamlessly transition from things like pop, rock, and EDM to orchestral arrangements and acoustic music with ease. As someone who's a little treble-sensitive, the Ultra is exactly what I wanted it to be, though, as the saying goes, be careful what you wish for. While I honestly love the way it sounds, there are times I find myself missing some of that definitive planar zing, energy, and engagement that the 2024 model does so well. Initially, I thought that the Ultra could serve as a replacement for the 2024, but I think for me, the answer is to give both a seat at the table and a place in my rotation. Each one offers a unique take on a similar tuning target, and neither really supersedes the other. The Ultra will take its rightful seat next to its golden-colored sibling, and both sets have risen to be my co-favorite planars to date. Letshuoer may have actually saved the best for last, especially for those that enjoy a smoother take on the traditional planar sound.

To give you a different perspective, I found the OG to be way too bright and the Pro wasn't much better. The 2024 hits right at the top of my tolerances and I really appreciate it for what it does well but it can still be fatiguing over long periods. For me, the Ultra is easily the smoothest and most agreeable of the S12 line and would probably please most consumers. So in my experience, each iteration has gotta better and closer to my target. Not everyone is a treblehead 🤷‍♂️. If each new release offers something different besides a different color or accessories, is it really milking it? Edit to add: per Letshuoer, this will be the final product in their S12 line so likely no Max version coming.

These are now available on the Letshuoer website. I also heard them at CanJam SoCal and agree that this version of the S12 sounds the best. Incredible bass with Coffee tips. Almost too much. Sounded best with the Eletech Baroque Stage tips. Best timbre I've heard from a planar.

My assumption is the Ultra was a repackaged S12 Anniversary edition, and that looks like the case. At the very least, I'm glad they "reissued" the set, as it was the best of the S12 lineup and compliments the S08 very well. Letshuoer has really nailed the DD-like timbre with some of their recent planars.

I think they were paying attention to what Michael Bruce/Shortbus was doing with the Glamdring mod and changed their tuning philosophy. The S08 was basically a mini Glamdring, without the collab attached, and the 2024 felt like a very natural progression from that. I hope they continue down that road. At the very least, I know Michael Bruce is happy now that he can work on his own projects now and stop taking mod requests from anyone that tracks him down.

I'm on a similar boat, but I'd dare to say that they sound lifeless to me. I do own the wu heyday and other half a dozen non planar iems and, honestly, I need to sell the s12s. The source doesn't matter, being it a desk amp or a usb dongle, they sound thin, weak and way too bright.

I got these a few months back and they are my new daily. Love them

Truthear Hexa might be good but I personally recommend the Letshuoer S12

Under 50$: Tanchjim Zero Ultima DSP, KZ Saga Under 100$: Sliivo SLA3, Letshuoer S12/Artti T10, Kiwi Ears Airoso, Under 200$: Kiwi Ears Aether It is really hard not to love these!!

Letshuoer S12 but it is a little bright, but it is very fun! Letshuoer S08 for warmer tuning

I got my S12 from letshouer and i really like em. An aluminum build, good planer driver, natural sound. Or other wise maybe the nick ick ft1pro?

Hifigo on aliexpress is currently doing a clearance sale [here](https://www.aliexpress.com/item/1005006856772123.html). consider finding another 10$ and buy one of the 8 remaining s12s. i guess if you *really* love bass you can get the 7hz Legato. absolutely no clue on the other offerings. Actually now that i think of it. You might as well get a artti t10 if you are interested in the s12s. basically the same expect cheaper.

Yeah, that's what it is for me, too. I listen to the Letshour S12 a lot, and it has a metallic timbre, especially on acoustic guitars. Great iem other than that, though. I like planars because I listen to a lot of busy, progressive rock, and they are fast enough to handle it with alacrity. I'll try this new one and see if it can replace the S12, but I run mainly with the iFi Go Blu. Hopefully, that will be enough power. It drives the S12, but that's a smaller diaphragm. I have desktop amps that will surely drive it, but I listen to headphones at the desktop, where the Edition XS is my go-to planar.

Moondrop Chu, and no. The Kato is the only Moondrop iem I still have and use. I liked the Aria but gave it to a friend to try to get him into iems (I failed). The Chu was good enough to get me into iems, but not good enough to keep me listening. I don't even know where they are now, lol. Of the early iems that I bought, I only have and listen to the Truthear Hexa (lifeless but decent, with wonderful imaging) and that Truthear Harmon-tuned one that Crinacle did with the subwoofer (I forget the name). It is fatiguing, but it is exciting until it wears me down. Good for techno. I listen mostly to the Aful P5, the Chopin, the Letshour S12, and the Kato now. Sometimes at home, I listen to the P8 and the Xenn Mangrid Top (they are too expensive to lug around with me--I have a $200 limit on iems that I'm willing to take in my backpack).

Letshueor s12 is what I would get for around 100$

I have both of these and they have basically complete opposite sound signatures. The MagicOne isn't bright. It's more midrange focused, slightly warm (but not bassy) and quite soft-sounding. It also has very good imaging despite not having fairly subdued treble. The S12 on the other hand is v-shaped with quite a lot of bass, which is very clean because of the planar driver, and a *lot* of treble. Overall it's very bright and highly resolving, but can get a bit fatiguing after a while. The MagicOne is very relaxing and neutral-sounding without being boring. The only reason it's not in my top 5 IEMs is that it's unvented, so can have some issues with air pressure in the ear canals. It's my 3rd unvented IEM and out of the 3, it's the least problematic. I find it generally comfortable, but I wouldn't use it walking around outside, as that would most likely cause issues with the seal leading to constant channel imbalances (which is what I've found with the other 2). On a graph, the MagicOne looks fairly similar to the Truthear Hexa, but the Hexa is simultaneously more of a boring-neutral sound, a bit peaky in the treble and lacking in bass incisiveness. The MagicOne is much smoother sounding, but it has a very noticeable "softness" to its timbre that isn't unpleasant, but does make it sound more coloured. The Hexa isn't a bright IEM either, but it's more incisive in the treble than the MagicOne is. If you're specifically looking for bright, the Moondrop Stellaris is like the S12 with flat bass, and sounds a bit more resolving. This is the one to get if you want a resolution beast and don't care about anything else. But it's far too bright for most people. Another good bright IEM is the Simgot EA500 (the original, not the LM), but again it's a bit too bright for most people, though more balanced than the Stellaris. It's also doesn't have any planar timbre, so it sounds a bit more organic and correct for acoustic music, but it's still a very fast and resolving driver for a dynamic. It has excellent soundstage and imaging. The Moondrop LAN is perhaps a more sensible all-rounder bright-neutral option that's bright without pushing it into fatiguing territory, although it doesn't get close to the technicalities of the Stellaris or EA500.

Since I eqed my s12's midrange to elysian tuning, I struggle to tell a difference.

I used stock silicone before. Now I use fiio hs20. Eq still the same. https://imgur.com/a/mDmjjM3 Might be too much midrange, because this eq is inspired from elysian gaea.

Happy it helped! I think pro gamers double up to block out crowd noise haha. I'm just thinking of CS pros, so my knowledge on that is limited. >Drivers, what are the pros and cons of single, dual, hybrid, etc.? I'll give the **pros** for each first. So the most common driver for IEMs out there is the balanced armature (BA) driver. It was the first major alternative to dynamic driver (DD), and allowed makers to put multiple drivers into a small form factor like the IEM. Each driver than concentrate on a specific frequency range instead, given the manufactured cared enough to put enough crossovers and tune them. Otherwise you have a bunch of drivers doing the exact same thing, defeating the purpose of having a multi-driver setup. These days it's hard to find an IEM without BA involved. Hybrids typically refer to a combination of BA and DD. One *seemingly* weakness of the BA design is its bass. Actual "weakness" is interesting and not an actual auditory weakness: [/u/oratory1990 made a great post about it](https://www.reddit.com/r/oratory1990/comments/nk243a/comment/gzdlw80/). DD is far more forgiving, so you can have it handle the bass while the BAs handle the rest. Tribrids are usually DD, BA, and electrostatic (EST) drivers. EST on paper is very accurate which translates to great detail retrieval. DD for bass, BA for mids, and EST for highs. More recently we have quadbrids. Uncommon so multiple flavors. Usually begins with the tribrid, then adds bone conduction (BC), piezo (PZT), etc. All have their quirks in terms of sound, but I wonder if that's inherent to the drivers themselves or not. The outlier is planar magnetic drivers. On paper planars are extremely fast, can reproduce the entire spectrum very well. These days they're typically packaged in tribrid and quadbrid flavors. Of course there are other driver combos, but these are the most common. Now, the **cons** of each. In terms of sound? Nothing. There are fantastic IEMs for every driver configuration out there. 64Audio U12T is all-BA, Sony IER-Z1R is a hybrid, ThieAudio Monarch Mk. II is a tribrid, and ThieAudio Origin is a quadbrid. I think it has less to do with what kind of drivers and more to do with how the manufacture designed/tuned it. Also it depends on your preference of sound. In terms of fit? All BA tend to have few fit issues because the drivers are tiny. Hybrid/tribrid/quadbrids can have fitment issues due to the large DD--some of the most uncomfortable IEMs feature the DD (IER-Z1R, Monarch Series, etc.) Planars are large, too. Single DD IEMs tend not to have fitment issues, either. Price is an issue. EST and planar drivers are more expensive, and it reflects in the price. **Original post category examples:** Not a comprehensive list, just rattling off the top of my head. - neutral tuning: Etymotic ER4XR/ER4SR, Hidition NT6 - mild-V/U+V/U tuning: Sony IER-Z1R, ThieAudio Monarch Mk. III, Symphonium Crimson, UM MEST Mk. II - bassheads: Sony IER-Z1R, FatFreq Maestro SE, FatFreq Grand Maestro - trebleheads: Letshuoer S12 (I think people don't like "spicy" sounds...)

I’m not you but I fucking love my S12s. The gold standard for me. Listening to my new headphone amp: FT1s, HE400se’s, Lunas…this is geometrically better. My never sell pair.

But that's not to say you won't notice a difference!! It just isn't overly dramatic imo and it seems like you have high expectations. I recently purchased the letshouer s12 and grabbed the chu2 shortly thereafter to sort of compare the two but also to have a decent set of buds for on the go. The planar s12's definitely have some very nice clarity and sharpness, the crisp bass response is definitely interesting - but it's not some revelation of newfound sounds I've never experienced before 🤷‍♂️ maybe I had my initial expectations a little bit high as well

I choose planars and DDs. With EQ they can be great! DDs are super cheap, as for planars, I've owned the s12, and KZs PRX, as a platform for EQ, is super close, if not the same, just way cheaper. I could be outta the game with a cheap huaynxin DD, or a KZ pr2 I got for 8 bucks, and EQ.

S12 may seems not wide enough for be, if you ask for more rounded details with space, the kbear Kb16 is a better choice. i have both, S12 very V share for vocal, KBear has all characteristic of S12 but the local a bit far aways so you can hear more details

I'm just a budget guy, but empathizing with the basshead stuff. I add a +15 ( or more) shelf to my S12s and still not satisfied. Never heard the deuce, but use it as a baseline target on various sets. For $15 you can pick up an 80 ohm, which should make a big difference. I'm assuming you prefer avoiding eq for convenience. 15 ohms doesn't do it for me. Personally I add a couple DB of sub bass over the Deuce target together with a 75+ resistance adapter (eq and plugs are sonically different and not interchangeable). W/ this setup, bass on the E20 and Castor Pro is absolutely ridiculous, leaving the Legato w/ shelf and Rosefinch w/shelf in the dust. Both sub and mid.

if you stretch they will be better, but there are decent options in that range. the s12 is a very good planar for the price (slightly over $100 typically), extremely good value especially with an eq. I own the simgot ew300 and it sounds quite similar to the s12 with some tonal differences. imaging is about the same, sound stage a little better on the s12.

haven’t tried it but I’ve heard great things about it. on the ew300 the treble is quite loud and same with the s12 and most other planars in general but the ew300 comes with different rubber rings / gold nozzle that makes it noticeably tamer. with the s12 you’d just have to eq it probably, but it wasn’t super harsh just a bit much for me personally.

I was going to mention that, planars do have a sort of tone difference. sometimes a nice DD is what you need lol. the ew300 has 3 drivers including a planar but it should be mainly for the mids while the dd does the bass and pzt for higher treble (\*\*\* I am assuming \*\*\*) so I don’t hear a metallic sound like the s12 but it didn’t bother me personally, I liked them both a lot.

thanks! though, might i ask if theres a sub 100usd set that has good details and bass? im looking for a different flavor from my usual s12. or should i probably wait for future releases(?)

i wonder how good will the Letshuoers s12 be, which i got for 95eur & still waiting for the delivery in few days.

I just got my second iems. Letshuoer s12, which i got for 95€ on sale. i expected them to have more bass, sometimes it is just not present, at other times it is decent. Overall i'm happy with their quality so far, they are great addition to my KZ's & ATH-MSR7b's, both on the bassy side. It's the first head/earphones that i own to not tire my ears in busy songs, especially with more trebbles. They sound fine with cx31993 dac, but there is no problem with driving them by phone alone. No hiss, no noise from the normal source. I used EQ by oratory1990, in some songs it helps a lot, in other i prefer the natural tuning. At some point i will change the tips & maybe cable. I'm looking for more EQ presets for powerAMP 10 band. If someone has good personal presets, let me know.

UPDATE : next day they started playing even better. I lowered the preamp in EQ and now instead of 30% of volume i'm running it on 65-70%. More power helps a lot. Listening to more bassy songs and it's a lot better than it was yesterday. My guess is that the foamtips get more adjusted to my shape. Cables & speakers warming up is bordering on audio-voodoo, but let's say they settled in better. They are definitely my favourite go-to earphones now and i barely feel them in my ears even eith largest foamtips. İ may actually prefer them over my ath-msr7b's at the moment. At some point i will try to find a dac/amp i could use for both. Maybe a dap. But i'm happy with them and excited for morr potential in the future.

ofc, but imho it's not worth 35Eur difference. i can always mod them later for that money.

Yeah, s08 & z12 were my go-to's but s08 were the same price & z12 are twice as expensive for whatever reason. 200€ before sales on ali, none available locally. And i heard s12 (especially pro's, which just have a foam filter over s12) can be tuned to s08, so i decided to go the cheapest route.

Me and my mate got into iems around the same time. I got CCA hydro, he got s12, we were both disappointed with the s12. I don't understand how they are so often reccomended.

A cheaper IEM being my most favorite? No. No cheap IEM cam come close to the expensive sets I have, but I do rotate through most of my collection over time. There is no comparison between listening to music on my Diva or my Glacier to any of my cheaper sets though, the gap is pretty significant. But, if you would ask me to choose a single cheap set and get rid of everything else, it would be the Letshuoer S12.

I like the S08 a lot, but there are some things going in to a purchase to be aware of. 1: As a planar, they have a particular sound signature, aside from the tuning, that I would describe as 'responsive attack'. The driver just has this timbre and responsiveness that is immediate. It contributes to both the 'fatiguing treble' and 'weak bass' that some people complain about when discussing planars. Notes that would decay, bloom, or bleed into other regions just don't do that as much. They pop and disappear and leave space for the next note, in my opinion. I personally love the responsiveness - it's great for music with quick bass lines, or if you like a 'bump', rather than a 'boooooooom'. Now, you can tune some of these things in or out of planars and other drivers (DD's specifically, for that loose and thumpy bass), but it's just how planars start as a default. Speaking of the tuning.... 2: The tuning on the S08 tries to avoid some of the 'planar negatives' while leaning into the note attack. Specifically, the treble harshness is tuned down a little (when compared to something like the 7hz Timeless, or Tangzu Zetian Wu, or the Shuoer S12), but that mostly lends to an easier listening experience by reducing fatigue, imo. The treble is still crisp and lively because of the driver, but slightly reduced in overall db (like 2db when compare to the S12). This does leave some people to just say 'just get a DD' when comparing graphs, but that take completely discounts the timbre of a planar. 3: ...and despite the reduced treble, you can still open it up a little if you're willing to spend a couple bucks on top of the iems for tips. The S08 take REALLY well to short-barrel, wide-bore ear tips that raise and open up the treble a little, specifically tips like the Moondrop Spring Tips or Tri Clarion. It's not much, maybe a couple db max, but that's the difference between the S08 and the S12 in tuning across most of the treble range. The thought of 'well if you have to buy tips on top of the S08 to make it sound more balanced, just get the S12' is fair and valid, but there are some peaks on the S12 that the S08 doesn't have; if you don't like those peaks specifically, the S08 and a set of Spring Tips is a better option. I decided to put my S08 in as a wrote this up - they really are a stellar set of iems, specifically for the price. I personally love that responsiveness of a planar, without some of the harsher peaks that others might have. The S12 is also a good option - it's treble really isn't that much more intense overall than the S08, but it does have some real peaky spots that stick out that I personally see as a negative. The S08 aren't really all that 'dark' in the treble, just much more 'flat' when compared to a Harman curve.

I really like the Letshouer S08 myself for that range, even over the S12. Pair with some Spinfit W1(more bass) or Moondrop Spring Tips (open them up a little, more treble) and they really compete. They have all the best attributes of a Planar (immediate punchy feeling responsiveness) while avoiding a lot of the bad parts (none of the peaks that can be fatiguing for some people, like the S12 has). There is a lot of personal preference to this though. S12 are also really good, but people tend to recommend the S12 pro or 2024 editions, which break the price boundary by a bit.

I am in love with the Letshuor S12

Is fairly good, a technical planar, but the treble is somehow foward, so, as long as you like that, is s nice, well build set, and thats a nice price too.

I have both Kiwiears Aether and Letshuoer S12. Both are great but i prefer Aether by far, sounds so good. Both take eq really well. The Aether is weirdly also more comfy even if the shell is huge, the contours on it probably helps alot.

Letshuoer S12. They made like no fun at all.

I have a pair of £80 iems Lestshoer s12s I’ve had AirPods and even some high end TWS and the sound doesn’t compare. However I’ve also owned £450 sets of iems and to me the difference in sound quality isn’t worth the price. I went down a rabbit hole and wasted months of my life doing research. I ended up with a DAP Hiby m300 and my s12s and I’m happy with that . I do also love plannar open backs like the hifiman Sundaras they are quality for such a reasonable price.  But every single person on this planet has different hearing, different expectations and different sound preferences. Most people who have Bluetooth headphones probably love the bass. But audiophiles love little details , I also love hearing noises or instruments that I’ve never heard before and you just don’t get that with most Bluetooth headphones. 

Letshouer S12 Are absolutely amazing sound and very small think you can you get them for around $80 .

I've tried the KZ PR2's, Letshuoer S12 and Kiwi Ears Aether. Of the three, I enjoyed the sound of the Aether the most and the comfort of the S12 the most. The PR2s are an absolute banger at their price.

Letshouer S12 is still my favourite and hard to find better for the price

You should give the Letshuoer S12 a go, good punchy bass and a balanced treble. I love mine.

I brought the S12's first. They were too screechy for me. Then I got the MP145, and thought they sounded really, really good. I then got some Crinacle Zero 2's as a travelling set, they are okay, but, you know, budget, so for me weren't in the same league, but I'd have gotten over it if they went missing or got damaged. Can't really remember what I went for after, but did realise the £200ish area is where the action is for me. It's all about the tunings now. I generally like a "warmer" profile, so the Septet were a bit of a risk, but I love them, in the right circumstances (they're not an out and about set). I'm not sure what advice to give really, graphs don't mean that much to me, they give a clue to the sound, but aren't going to tell you whether you'll like it. I have different sets for different moods, where I am, type of music etc. One and done? That's tough. More than likely the Martilo for it's versatility, but I'm on holiday at the moment and grabbed the KE4. Guess I'm lucky I can return home to the rest of the kit! For the record I use a BTR15 Bluetooth dac or M21 dap when I'm out, and a FIIO K7 as my desktop.

I have letshuoer s12 and if it is for competitive use and the treble damages your eardrum, I would not recommend it. However, you have the FiiO fh3 for around $90-$95 on aliepxress. They are IEMs whose normal price is $150. Its soundstage is a little above average. Treble well detailed and informative but not tiring or damaging. Bass present and full-bodied, sub bass accurate and the mids somewhat retracted. What I like about the FH3 is that they perform well in any video game just by changing the tips. However, for competitive purposes, the balanced ones work very well.

Letshuoer S08 are excellent but if you liked the brightness of the EW200 then you might prefer the Letshuoer S12 instead.

I'd argue with a bit of eq and a higher listening volume the s12 can be pretty fun. I have the s12 pro which is supposed to have slightly more bass and smoother treble, and they're my favorite V-shaped iems, but when I made my friend try them he said he heard just treble, until I raised the volume up a bit. Sure they're not for everybody, but I guess it's easy to look past them before discovering their actual potential

used to spend thousands on audio gear. Not worth it ultimately. Yes, I absolutely loved my Focal Utopia, but I enjoy my HD660S and cheaper IEMs just as much. My recommendation is to buy a selection of cheaper IEMs, it will help you discover sound signatures, as well as what fits you best. The LetShuoer S12 and other planar IEMs like NiceHCK F1, Artti T10 are crazy value for the level of sound quality. Refer to [https://squig.link/](https://squig.link/) for frequency curves.

I dont have many but listening to metal feels great with letshuoer s12 by my experience

Currently enjoying the Punch Martilo. Managed to get a good discount. Very comfy too. My favourite pure planar was the S12 with eq.

I love the Letshuoer S12s for metal and rock. Super clean sound even without EQ. Love love love, I was hunting for a while too. These are the last IEMs I’ll buy lol

Not a lot to be completely fair. 7hz zero ($20 iem), dunu titan s, letshuoer s12, moondrop chu. Either way I just feel like they don’t do what headphones do.

After 2 weeks of waiting, my Elysian Pilgrims from HiFiGo finally arrived. And BOY were they worth the wait. I am still relatively new to the IEM hobby, but I play a few instruments and had dabbled with many audiophile level speakers and file formats. Two years ago, I purchased my first serious IEM, the Letshouer S12 for about 150 USD. These Planar magnetic IEMs were frankly amazing, and they served me incredibly well for 2 years until i felt i was ready for the further step. I seeked more technical detail, more detailed and better bass and treble response. I don't know if its from constant use but my S12's would feel a bit "muddy" and lacking something. The black friday sale on hifigo had these at 343$. https://preview.redd.it/rhcavnocdq4e1.png?width=1893&format=png&auto=webp&s=a5dc1c6f4df8d7cb3bb0bb856ee74176586b9cb0 # Shipping Frankly, slightly disappointing but they handled it really well after contacting support. They get a solid 3.5/5 for this. It seems hifigo actually didnt happen to have the IEM in stock at first. I asked support to try their best and they managed to ship it a week after I ordered them. After that, shipping took no more than 6 days and was smooth with no issues. Maybe its just how the chi-fi industry works but I was shocked initially when they told me it could take up to 2 weeks to get the product in stock despite them having it on display in the website saying it was available for sale Moving on. # Build The Pilgrim comes with a very well made case, 3 pairs of spinfit tips of varying size and a very nice 1 year warranty card. The IEMs and cable themselves are very well built. The pilgrim has a well built Metal body (1DD+2BA drivers) with a fairly large nozzle. The body of the IEM has slightly sharp edges but nothing too much to worry about. The cable has these pentaconn ear connectors - I'm a fan of these. One irritating problem you will face if you get these is that the stock eartips provided with these IEM's are a little small for the big nozzle of the pilgrim. They took me SIGNIFICANT effort to actually install the spinfits on the pilgrim (a good 15 mins actually). 5/5 # Sound These frankly blew me me away with how good they are (using lossless audio). The tuning is a very balanced somewhat (?) of a V shape and is a little safe and warm. I thought I was hearing minute details on songs with my S12's - I WAS WRONG. I put these on and I can hear even more details on songs Ive listened to 100s of times. The small buzz from the recording mics, little nuances used in beats that now show up. Instrument seperation is fantastic. The technicality on this thing is A+. The bass is probably my favorite part about this IEM - and im NOT a basshead. Its done almost perfectly. Its not overimposing, tiring or too low. Its just at the level where you can enjoy it and not get tired at all. The bass compliments and doesnt impose itself where it isn't barging its way through other sound features. The mids and treble can both be described as somewhat "bright" and "well rounded" they both work well together and allow the bass to have a presence as well. The soundstage while above average, can be a little better imo. Overall, an incredible product at the 350$ range. This isn't my endgame, but i'm not moving to another one for atleast a year. Thanks for reading this review. Final score: 4.5 ⭐️ out of 5.

I got the s12s last week and the lack of bass surprised me coming from the Sgor Luna and Artti T10, but have now dialled them in to a level I absolutely love. I use the FIIO JA11, which I use to increase the bass, but found even then some songs lacked bass where I would have expected it. I only normally use medium tips, but tried large and this improved things considerably too. The great thing about these and planar drivers in general is that they'll respond really well to EQ to get the sound you want

I've tried Letshuoer S12, Simgot EM6L, Kiwi Ears Astral, Ziigaat Arete and briefly the Softears Volume S. In terms of ability to pinpoint enemies the Astral, Arete and Volume S are the best but EM6L is close. So any of those will generally do you well. Imo the S12 and Volume S are too treble leaning and just makes it generally unpleasant to listen to most the time. The Astral is very V-shaped and has a tonne of bass which can be fun for some games but in competitive ones gets annoying (I had to EQ them to bring the bass down). For me the Arete and EM6L is more subtle and simple and I have no desire to EQ it. Also the tea pro is probably just not worth that amount of money, from my testing after £200 you really hit diminishing returns fast. I personally use the Aretes.

I bought the s12s on sale and had slight buyers remorse not getting the pros or 2024/ultra on sale instead but now I'm good with it. S12s were a nice upgrade from 7hz zero:2s.

**Update**: today I received Letshuoer S12, I think this is my end game all things considered. It's like a HD 6xx, beyond that I probably cannot tell a difference. Sound and tonality wise S12 is exactly what I need -- at least I don't know what else I need. All the albums that I played today were awesome, not in the sense of "wow! it's so different with so much bass vocal so forward" but the feeling of immersive, and forgetting the existence of the earbuds. I've never tried "better" IEMs, my only reference device is HD 6xx as an amateur music lover, not an audiophile. I feel it's natural or neutral, not too much bass, but when it's there I can strongly feel it. Treble isn't suppressed or boosted artificially, and I don't feel ear-piecing or fatigue after a few hours. In the metaphor of drink, this is like a spring water, not a coffee or vodka or wine. I like it, not like just the device itself but I feel it's not getting in the way of enjoying music. It's quite comfortable. I picked the small black silicone eartips. I didn't try the foam ones -- supposedly it gives better bass but I don't need more bass. By the way, what's the difference between black and white set of tops? Only for cosmetic reason? The quality seems good to me. The connection from wire to buds are metal, all my previous devices are plastic. The 3.5mm plug is metal, the buds are also metal, I like all metal stuff. The shape of the buds are "traditional" and not weird, it's low profile. The wire is thick and sturdy and flexible enough. It even has a nice looking carry box. I don't feel I need anything extra, other than extra eartips it doesn't have anything extra either. Compared with Tanchjim Bunny, S12 is better. I cannot say it's 4-5 times objectively better, probably in 80-90% of scenarios Bunny is no worse, but in some "tricky"/challenging tracks I enjoy the music and don't notice anything else, that's the difference brought by extra $80 - which is less an hour of salary, totally worth it. On the other hand, Bunny is awesome too, I will not leave it behind. Thanks everyone for your precious opinions to guide me find this IEM. It's truly satisfying to find what I really like. Your guys rock!

Any Planar set along with mid range DAC. My all time favourite setup is"S12(planar)+AP7(DAC)" Also my main genres are Rock/Goth/Alternative and I'm more inclined towards and prefer songs with female vocals with the above said setup. Songs like these as example https://preview.redd.it/n3y2c2kuj0bf1.jpeg?width=720&format=pjpg&auto=webp&s=ea48e20336300772efe6137d9cdda01f031d83cf S12 kinda separate the vocals in a decent way but only issue is it's bit flooded with the high frequency section. So far the I can bare it up when S12 is using with Jcally AP7 DAC because AK4377CEB chip on the DAC cuts-off little range from high frequency section.
