"I have the ear shape where in-ear headphones always make a loud bumping sound when I'm moving, so AirPods 4 give the benefits of noise cancelling and great sound without the in-ear effect. ... AirPods 3 always fell out my left ear but they dialed in the size perfect for the 4's, they sit perfect and I've never had it fall out or shake loose doing sprints and a full marathon."
"Took them on a 2hr walk with my dog today and had no issues. First IEMs I can actually wear laying on my side in bed."
"after 80+ miles on our last trip, I was the only one without foot problems of any kind."

"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"
"Can't recommend them enough for the value, sound like $200 earphones."

"the bass on the Explorer is fuller. ... when you do get that ear rumble, it elicits that reflexive body feeling of a deeper core feeling to it. ... The Explorer is just musical enough to satisfy that for me."
"KZ castor has more boomy bass, so its great if u need more immersive sound with a lot of explosion and gunshot like Battlefield and Squad."
"the OG castor bass are my go tos for anything hardstyle (uptempo, raw style etc) lol, they’re incredible for that"

"For me I think the S08 has a very nice rumble. Especially for a planar iem. ... In fact, in many ways Letshuoer bucked the planar trend by coming out with planars which sound remarkably similar to dynamic drivers in timbre but the speed of a balanced armature. ... Truly an awesome sounding set which easily competes with more expensive sets. ... Very musical, rich in note weight. ... I feel that for metal you'll be hard pressed to find many better sets under $100. In my opinion."
"But as someone who gets ear fatigue these have been godsend."
"I love my Aful Explorer ... Beautiful IEMs with a warm, rich sound signature that I adore. ... I gotta have my full bodied mids. ... what I love about Explorer (warm, rich, mids) ... Mainly trying to find something that doesn’t make a violin section sound thin—it needs body and richness for me."

"i have QKZxHBB and i dont think it has much problems of sibilance, if anything at all ... I dont hear sibilance honestly"
"Especially with regard to micro details, fine nuances and subtleties, they IE900 excel given the right source and audio files. ... Upper frequencies on the IE900 are never fatiguing, always in control and did I mention the extension? Simply amazing what Sennheiser can do with just one small 7mm dynamic driver here. ... Many multi driver IEMs would (still) struggle to compete in bass and treble extenion vs. the IE900. Simply put, it is "flagship level" treble here (as it should)."
"Regarding the treble, definitely an improvement compared to the ZS10 PRO X; They are not sharp like their ancestor, they are well detailed, but they do not penetrate your ear causing that characteristic discomfort. It's so soft to hear the cymbals sizzle after the beat, but without that feeling of penetration."

"I don't feel any difference in bass"
"However, the sub-bass isn ’t particularly strong and can feel a bit sluggish when stacked against higher-end models, as the layering and separation in the low-end just aren ’t there, which can lead to a muddled presentation when a lot of instrument is going on in the mix."
"Unusable without hefty EQ (-10dB @ 185Hz). ... That spike at ~180Hz is real and ruins low-mid end completely. ... Any sound in (or passing trough) ~180Hz region has some strange tin can high pitched hollowness/echo. ... Bass guitars sound strange, drums sound strange, low vocals sound strange... Any background hum in music/movies/games sounds strange. ... It is also very hard to EQ out - spike is very high and in very narrow range. So you need good EQ software to apply a lot of negative EQ in very narrow range (used EQ APO+PEACE). ... Once EQ is applied these sound quite nice. Good low end, clean mids and nice highs. Without EQ they just sound wrong."

"The upper mids of the Cadenza are what disappointed me the most. It's just dead feeling."
"hexa absolutely demolishes delci in that front."
"the RE2000 blow Explorer out of the water - especially in Detail. ... The amount of detail and precision that the RE2000's manage blow the AFUL Explorer out of the water. ...

"But they are power hungry, you need a good source. ... Your phone will provide enough volume but all micro detail will be lost. ... I have tried my Explorers on different sources, for example on Apple dongle they sound like shit, on macbook and ipod classic 7 they sound fine, on 3.5 my dap has 250mW off power and it starts sounding good, but ONLY on 4.4 of my DAP which provides 600mW of power I was able to hear how they TRULY sound. ... In all this cases they are loud enough but amount of detail and distortion is different, the more powerful source you will provide the more details you will hear and less distortion/noise you will have."
"But, these are power hungry af."
"Mine just arrived… and I found it weak as hell. ... Max volume on both my phone and PC, and the headphones just don’t deliver. ... the bass adapter just makes it more bass tuned but also even lower volume. ... I don't understand how these new IEMs needs a external amp to get even closer to what those old Razers could deliver with just the power of an 3.5mm jack lmao"

"If you plan on gaming, then the Aether wins hands down. The Quinte is more intimate and has worse imaging than the Aether, in my testing."
"Not every type of music sounds good on them - I don't recommend them for symphonic music, or where there are many instruments (due to small soundstage)"
"Small details in soundstage are way more noticeable in detail & positioning. ... RE2000 isn't a soundstage monster but is definitely wider and more accurate/precise than Explorer. ... That oscillating sound around 10–30 seconds in feels super wide and immersive on the RE2000, like it’s “breathing”. On AFUL, it stays more inside my head. ... Soundstage feels small and intimate."

"the low eargain just makes vocals sound recessed to me, yet also sibilant at the same time. ... So it's kind of the worst of both worlds for vocals. ... I tried a lot of tips and couldn't fix it ... that one issue just ruins everything."
"Much better in higher frequencies as well. ... Vocals aren’t bad, but not as crisp or detailed ... The female voice sounds more like a ‘child’ on AFUL vs. older/seductive on RE2000 - not sure why, but it stood out. ... Vocals are good, but not very forward. ... Vocals would be much better on RE2000 than AFUL Explorer is my impression right now…"
Warm and bassy? I’m loving the Aful Explorer. Not a true basehead iem, but warm, smooth and relaxing
'without too harsh highs' definitely not, they're a bright set i'd consider aful explorer actually for a hybrid option
i'd look into the aful explorer, quite similar but they'll be more smooth in the treble
aful explorer - for a warm *smooth* listen mp143 - warm but more detailed listen
What would you say the upper mids/treble is like on the Luna? I’ve got the Aful explorers and I like the overall warmth of the set, but I want something with better detail on the upper minds/treble. I listen to a lot of breakcore and the Explorers feel sort of low res in that region
I have the Explorer so I'm very interested in hearing your comparison between those two.
I love my Explorer with the S&S, it's my top choice. I have tried Zeos Render, Penon orange, Nicehck C04, Zhu Rhymes bamboo, kbear coffee and have always gone back to the S&S. Having said that, eartips are very personal choices for different people so just stick with whatever feels best for you.

I have all three IEMs, the Kefine Klean is good for $49 and if you change the stock cable it improves the bass and treble becoming warmer if using the Nicehck GTC5 cable. The Lesthouer S08 is a very good warm planar IEM I think is a really good option with the 25% discounts on Amazon US it comes out at around $66, but check the forums on Amazon it says frequently returned there are users who report problems with the right earbud, I have not had any problems, they sound very different from the Kefine Klean, the sound is somewhat dark with soft and detailed but not extended treble. The best for my personal taste is the Aful Explorer but it is the most expensive $119.99, it has a very organic warm sound, with good bass and detailed and sweet mids with a narrow but very musical presentation and the treble is somewhat attenuated with a certain level of detail. Any of these IEMs are wonderful but if you have the money go for the Aful Explorer if you like the warm signature and good musical representation.
Of all the IEMs I have, for some reason, the one I like the most is the Aful Explorer. I also have the Kefine Klean, Kefine Delci Ae, Sivga Que, Kiwi Ears Airoso, Lesthouer S08, Simgot EW300, Hidizs MP143, and MP145. All of these IEMs have a somewhat neutral, warm signature, but they all have excellent, very different sounds. I recommend the Aful Explorer, it's the best without a doubt. I won't tell you about the Hidizs MP145 because they're too big and can have adjustment problems if you have a narrow ear canal. Another thing I recommend is that you play with different types of cables and eartips, they can make a difference.
I have the ISN H20 and they're wonderful, better than many more expensive IEMs. My absolute favorite is the Aful Explorer, followed by the ISN H20, above the Lesthouer S08, Hidiz MP145 and MP143, Kefine Delci AE, etc.
The Aful Explorer is the go-to when people want warm, smooth sound
AFUL Explorer is not new. Not even close. I’m skipping a wordy lead up and unboxing by hitting a few main points. - Love the case. Puck style with a zipper. The suede material to the case is very nice to the touch. - The cable is ok. Not cheap feeling but I chose a 3rd party cable as you can see in the photo. - Eartips. Good enough selection especially if these are your first IEM. I chose to use a set of modded tips (I’ll get into that a little further down) The photo does NOT do these IEM justice. I was taken aback when I opened up the box and able to look at the IEMs in person. The rich blue tones with the sparkles really is eye catching. These are not a large IEM and likely to fit most ears. My only issue with the build. Same issue i have with the Performer 5+2, as well as Truthear Hexa. There is NO FILTER at the nozzle. The openings to the sound tubes are completely “unguarded” which triggers my paranoia. This may do the same for some of you also. MY solution is to use ear tips that are equipped with “gunk guards” I chose AZLA SednaEarfit tips, specifically the ASMR Max. I like these shorter ear tips on my IEMs because they provide a deep ear fit. As I mentioned before, this specific set of tips are modded. I have used foam from a set of foam ear tips to fill the space under the umbrella or cap. Resulting in a short, filtered hybrid tip…perfect for my use and sound preference (with this set) Sound: The Explorer is a revelation. I’ve seen and read up on every review I got my hands on before buying. Each review said the same things… “warm” “smooth” “relaxing” “unique” I wholeheartedly agree with all those opinions. I think what does get missed is the details these can still reveal in a well mixed/mastered track. The soundstage is not wide, but the imaging is still superb. The bass is quite obviously notable. However, I prefer a bit more bass with this warm presentation. This is where those short hybrid tips come into play. The deep insertion plus the foam helped bring more “warmth” to the table. The resulting sound is NOT muddy nor was the treble veiled (which goes back to the details and imaging) The mids, specifically vocals, some of the tracks I listened to…the vocals seemed a little recessed. Enough for me to take notice, but not enough to prevent me from enjoying the music with this set. The Explorer IS that nice warm IEM you can sit on the couch or in bed to relax to. Is it my first choice if I want to do some critical listening? No. Is it a set I’ll pick up to vibe with my tunes…ABSOLUTELY. They perform well across genres: rock, pop, hip hop, edm, METAL! They are smooth and warm enough that JPOP and K-POP can be enjoyed at higher volumes without fatigue. Film scores (the good ones…😅) can come across as cinematic, particularly Hans Zimmer’s F1 and the two Dune sound tracks. The warm lush sound is not my preference for classical pieces nor jazz pieces. BUT, that’s just me. I really enjoy the vibe this set brings. It is my go-to for my listening session before I go to sleep. Definitely a good set to add to your collection if you have several others. If this is a prospective first set…then it’s a safe first purchase. Especially if you’re coming from TWS that are quite generous in the low end.
Peeps here touched on it. A GREAT IEM now…will still be a GREAT IEM in 20 years (if the unit lasts that long) Koss and Sennheiser each have headphone models and designs that have been popular and even revered for over 40 years. That said…IEMs like Truthear Hexa and/or Mega5est will have staying power because of their reputation at their “hyped” peak. I think AFUL Explorer will be one of those IEMs that will be talked about for a long time. It has a very warm, smooth, relaxed tuning (treble) that is not common at that price point. Am sure there are fans of kilobuck or expensive mid-fi IEMs that have their favorites that they’ll swear will stand the test of time. The IEM space is quite young still. Yes, musicians and artists have been using IEMs for a long time…but for those of us using IEMs for music/gaming it is still a young development. Good luck with your collection journey. Consider using a watch box to store and display your IEMs (if you are into that)
I love how smooth and relaxed the Explorers are. I listen to them when I'm not focusing on the music. Not in the sense I'm not paying attention...but not focusing to the details and nuance. It's a set I listen to for chill time. Think you're recognizing a misstep from when you first started...that's a lot of budget sets....that may or may not sound the same. Taking a methodical approach and you'll figure out EXACTY what you like and don't like (sonic preferences) Can't comment on those apps you're askign about. My EQ solution is on my computer or my DAP. EQ is a very useful tool to get the most out of your IEMs but also to dial down to what your ears like or don't like.
So what's ur use scenario? My suggestion in general for whoever enter this hobby (it they care about gaming) is getting the Tripowin Vivace+ Azla asmr max tips (obbligatory with this iem) cus i think even up to 500 there is nothing (in game) that outperform by a huge margin this. So if u care about gaming u can choose this combo first and then also buy an iem where u can focus only on ur music preferences (+ having the Asmr max automatically open u the doors for every harsh treble iem, cus this can tame anything). And with 120 u can do something like: Vivace combo+ Kz Am16 bass (best Kz with Ba rn and pretty cheap on Ali, meanwhile the best DD from Kz is in their Kz Zenith that i put way above the Zero Red if the qc is good). Anyway my favorite iem under 50 are the Cadenza, i read someone above saying that the Zero red is overall better, but for me the Cadenza is way better than the Zero red (not in game) the timbre is of the Cadenza is better (Cadenza Berillium timbre is my favorite timbre even up to 300) and the bass hit more satisfing and that bump in the high give u an impression of high technicality and is pretty berable + they are way more comfortable (worst than the Red in gaming if u use the adapter and obv they have a worst final extension in the trebble as u can see in graphs) some people prefer the Kefine klean in this price range and overall can do more things (especially in gaming) but music wise i prefer Cadenza. So i covered the combos...now let's talk about the best all rounder/sets under 120 (sometimes with discount) Kiwi ears Airoso (incredible iem for music,for me the best, a direct upgrade from Cadenza, not the best in game but still usable) Kefine Delci Ae (great valuable iem) Simgot Ew300 (not great in game, but 🔥 music) Juzear Defiant (if the qc is good, pretty close level wise to the Airoso if not better for someone) Arti t10/t10 pro if u want to try planar Truthears Hexa (neutral and all rounder, exquisite, better than the Red, but can be boring) Simgot Em6L (great allrounder) Aful explorer (if u want to raise the volume, this is great, in game they kinda 🙃😅) Tanchjim Fission (best 1DD at this price) Idk if i forgot something but this should be pretty 😏. This is kinda it i think.
If you have a pair of the wider bore that comes with zero red/hexa are great on the explorer
Explorer is a snoozefest in comparison to Defiant, but good for long sessions. I mean, Explorer is unique, but can be really boring even on your favourite tracks. Defiant is always engaging, less warm than Explorer, less flooded with bass but more punchy. Also more separated and organic to me, with better vocals. But Explorers scale very well with loud music. For me it asks for too much volume until it's considered fun. For some genres they could be the choice.
Aful explorer hands down. They are small, sound terrific, and usually go for less than 90-95$. Also they are beautiful to look at.
