Simgot - Simgot EA1000 "Fermat"

Simgot EA1000 **with gold nozzle** and AZLA Crystal **2** tips will fit all of your boxes **greatly**. DAC: Apple Dongle if you have it or Jcally JM20 Pro if you wanna go premium. If you're american and can't order Jcally because of tariffs, then Apple dongle is good. However, if you're on Android, you'll need to install RootlessJamesDSP and Shizuku for it to work properly or your phone will keep not using the external DAC.

I can agree with you on the bass part.. Loved the tuning of these IEMs and how they presented the mid and treble range was really smooth and relaxing FOR ME.. Just the bass felt a bit loud for my liking.. If you like these, then you would most likely love the Simgot EA1000s!

Honestly the squigs don’t do the fermats justice. It is the first IEM where i could hear music around me like phantoms. Borderline schizophrenic cause I’d be staring at different spots in a room to listen in on a sound or instrument. With the LMs I get the stage and air at the edges of the bass and treble frequencies.. This could all be “psychoacoustics” (whatever that means) and could be different for you.

While I don't currently commute much, if I'm going somewhere on public transport, I find that I prefer a more v-shaped tuning than usual, with a strong bass especially. I think maybe it helps with background noise, but also in general I prefer a more energetic sort of sound if I'm out and about. My current go-to is the Ikko OH10. I've been looking for an endgame for this use-case and so far, the OH10 is the closest, but not quite perfect. It could do with a couple more dB of bass (without EQ) and a touch less stridency in the treble. I will say though, it's pretty easy to make the OH10 perfect with EQ, it's just something I don't like doing because I'm always listening to different stuff and it's a pain to manage profiles. Plus it encourages never-ending tinkering and tip rolling is bad enough as it is. Some things I was hoping would unseat the OH10 but have not done so include the Aful Explorer and FatFreq Deuce. Some warm/bassy IEMs that I don't like as much for travelling are the QKZ HBB and Letshuoer S08, despite being my #3 and #2 IEMs overall, respectively. The HBB is too laid back. The S08 is let down by its bass, which can be a bit boxy at the best of times, but this gets exaggerated quite a lot when travelling, especially on buses. The Timeless AE is an interesting one in that it sounds perfect for walking around, but as soon as I get on a bus, it suddenly sounds like it has no bass. Been meaning to write a separate post about that one. I think there's something about "planar bass" and acoustic impedance going on there; something to do with the engine noise/vibration from buses. The same thing does not happen with DD bass drivers, regardless of whether they are midbass or subbass focused. I haven't had a chance to compare the Timeless AE, Ikko OH10 and Moondrop Kato on a train, but for a long time the Kato was my go-to for long train journeys. I find the OH10 is a bit ahead of the Kato for bus trips, as it's more v-shaped. I think if I'm going to spend 2-4 hours on a train, I'll still prefer the Kato. I'll also mention my favourite IEM overall which is the Simgot EA1000. It works for everything including travelling, but the Kato and OH10 are both warmer/bassier so those are what I'd normally go to for travelling. If I were travelling, staying hotels, etc., and wanted to take a single IEM for everything, it would be the EA1000.

\#1 is the Simgot EA1000. Pretty much the opposite sound to the S08. Tips I use on the S08 are Penon Liqueur Orange, but I don't mention it unless asked, in case people think I'm recommending they use the same tip. I'm not. What works in my ear very likely won't work the same in your ear. They're a good tip though and not too expensive, so worth having a set. They tend be be warmer sounding (more bass, slightly less treble). Also good if you have larger ear canals because they lean larger than average and go up to an XL, which is massive. I find tips help with both the bass quality and level on the Hexa. I use Zhulinniao Zhu Rhyme mainly for comfort reasons, but I find they also improve the bass a bit. I can definitely recommend those tips unless you have large ear canals, but if you have large ear canals then the stock tips might be fine anyway. I usually find Feaulle H570 have the best sub-bass extension in a generally neutral tip, and Zhu Rhyme are very similar but shorter/smaller.

Hey, I've been wanting to know more about these! The only review I've seen is from [Bangs Audio](https://www.youtube.com/watch?v=He3BSsOJZ_g) who really seems to love them. The thing is, I follow him, but I find his takes often disagree with my own, so I wasn't prepared to buy them blind. There are also no measurements on squig.link. Some of my favourite warm/bassy IEMs are: Ikko OH10, Ikko OH300, QKZ HBB, Letshuoer S08. I also have the Moondrop Variations, FatFreq Deuce, KZ Castor Bass. I'm wondering if you have any of these as another baseline for comparison? The EA1000 is my favourite IEM overall. I particularly like the way it does bass, although it's more what I consider neutral bass, despite being technically boosted on a graph. I find that acoustic drums sound extremely realistic on the EA1000, partly because of the way the bass is done but also the balance with the mid & treble harmonics. OTOH, I like the deeper, fuller, Ikko-style bass just for something different, or for electronic music, where the extra sub-bass emphasis works well (the EA1000 rolls it off intentionally to avoid sounding muddy). My #1 and #2 favourite IEMs are the EA1000 and the S08 precisely because they are polar opposites in pretty much every way. The EA1000 has that large, airy soundstage, whereas the S08 is dark and bassy, with a tiny soundstage. Yet the S08 also has really precise and holographic imaging, just compressed into a tight space. The comparison I like to make is if you listen to a live recording on both, with the EA1000 it's like being on stage, standing a few metres from the band. With the S08, it's like being trapped in a cupboard with the band, with the vocalist singing directly into your face. The only downside of the S08 is the bass quality is a bit lacking. It lacks the DD punch in the way planar bass usually does, and at the same time it also lacks some of the bass resolution & texture compared to something like the S12 Pro, and it can sound a bit boxy at times. I'd really like to know where the YU9 sits in relation to these. And if it's more sub-bass oriented, does it suffer from the same Harman midbass tuck as the Variations & Deuce, where bass guitars can sound recessed?

I tried ranking my IEMs a while ago. It gets harder to say after the top 3, but those are: 1. Simgot EA1000 2. Letshuoer S08 3. QKZ HBB Not a lot of correlation between price and ranking. The Variations is my most expensive IEM so far, but it's ranked a lot lower down because of the bass tuck and comfort reasons. It does have the best treble, but the EA1000 is comparatively about 98% - equally resolving, just not quite as smooth. The EA1000 has much more correct-sounding bass. It's only real flaw is the slight cool tilt to the midrange, which I would change if I could, but it also doesn't bother me. Everything else about the EA1000 is basically endgame for me.

I have about 50 IEMs, so it's a fairly long list. But my current favourites are: 1. Simgot EA1000 2. Letshuoer S08 -- currently tied with Ikko OH300 3. QKZ HBB 4. Moondrop Stellaris -- specifically with Dunu Candy tips^[1] 5. Moondrop Kato -- tied with Ikko OH10 (order changes if I'm inside or outside). 6. Dunu Titan S ^[1] Just because these tips work for me doesn't mean they'll work for anyone else - with other tips these are super bright and fatiguing to listen to.

The EA1000 is definitely the most refined of the Simgots I've heard, which is all of them except the SM4 and the ET142 (and the EA2000, but nobody cares about that one). It has that signature Simgot bright-leaning and airy sound with a large soundstage, but it has the best combination of resolution, smoothness and balanced tonality. Overall it's a mild v-shape with what I'd call cool-tilted mids rather than being bright per se. I'd prefer a bit touch more warmth to the low mids, but I'm not sure that's possible without ruining everything that makes them special, like the soundstage. I plan to do some EQ experiments at some point but haven't got around to it yet. At least for me, it never gets fatiguing (though it might for anyone very treble sensitive). It will certainly do electronic music fairly well, but it's not the *best* for it. I do think it's the best IEM for metal, at least out of everything I've heard so far. It's super resolving (very close to planar) so never gets muddled with complex arrangements, layered distortion, etc. The punchy bass is exactly right for any sort of rock music. Cry of the Blackbirds by Amon Amarth on the EA1000 is something else. Also Youngblood by Russian Circles has some great sounding drums, which on the EA1000 sound better than any of my over-ears. Only the Edition XS comes close, but it doesn't have the same weighty reverberance that sounds like an actual kick drum in a closed space. I'm using the red nozzle on mine which was the default and tbh I've never got around to trying the other ones. So I can't confirm red is the best, but most seem to agree that it is. I suppose I should try the others at some point, but I haven't felt the need to. I also like Divinus Velvet tips on these, thought that's a big YMMV thing of course.

The S08 doesn't sound like most planars. Haven't heard the MP143, but I do have several others like the Artti T10, S12 Pro and Timeless AE. The S08 is much darker and sounds more like a DD. Planar technicalities come through at times, without the planar timbre. Definitely no spicy treble. My number 1 is the Simgot EA1000. Brighter leaning mild V shape that sounds very open, one of the largest soundstages in an IEM. Completely the opposite sound to the HBB and the S08. I have about 50 IEMs and the S08 is probably the closest to the HBB in terms of the overall "feel", but with the differences I mentioned. I have some other bassy IEMs, but they all have more of a pronounced V rather than a straight warm tuning. For example I prefer the Ikko OH10 for walking outside, as it's more vocal-forward and more resolving, but the treble can get a bit strident at times.

EA1000 is my favourite IEM at any price, that I've heard so far. It's a very good driver, which easily competes with planars like the Timeless & S12 Pro as far as resolution goes, but it has better timbre. The quality of the treble is about 90-95% as good as the Variations, which probably has the best treble under $1000. I haven't heard the Timeless 2, but I have the Timeless AE. Haven't seen any comparisons, but I suspect the T2 is very similar to the AE. The [graph](https://audioamigo.squig.link/?share=7Hz_Timeless_AE,7Hz_Timeless_2_Gold_STD) looks nearly identical. The AE is quite bassy, mainly sub-bass focused, so is good for electronic music. A bit less spicy than the S12 Pro, but still very much from that generation of planars with similar planar timbre etc. It's maybe 5% better than the S12 Pro, for double the price. The EA1000 has a bit less sub-bass, but it has really exceptional midbass and makes acoustic drums sound more real than any other IEM I've heard. I don't know if you've heard the original EA500, the EA1000 is basically that, but more refined, less spicy treble, a bit better timbre (which is already pretty good) and better bass quality. I didn't really like the LM compared to the original. The extra sub-bass ruined the soundstage and masked a lot of the ultra-detailed sound the OG has. The EA500 actually sounds slightly bigger and has sharper imaging because it has so much extra treble. The EA1000 is still about 95% of the stage size & imaging precision, but much smoother and more natural sounding. I did some experimentation with the LM while I had it, but nothing I did could make it have the same magic as the OG, so I ended up returning it. The only thing I would change about the EA1000 is it has a Harman-like cool-tilted midrange, so male vocals can be missing some huskiness compared to some warmer IEMs. It's not a true Harman tuning though, because it doesn't have the midbass tuck. I haven't heard the ET142 so I can't compare, ~~but I did check a few reviews of it before and it sounds like the treble is a bit harsher than the EA1000, because of the PZT. That was the thing that put me off trying it.~~ Edit: It wasn't the PZT, it was something else, but I can't remember why I wrote this one off. In fact, most of the trustworthy reviews (Paul Wasabii, Audio Amigo, HBB's updated review) are very positive about it and it has a more S08-like treble tuning with some of the nozzles (which is a good thing).

I don't know where the ET142 sits in that order but I'd put the EA1000 ahead of the Timeless - at least the AE. The main difference I think is going to be in the bass. The bass on planars is generally more resolving, but less punchy. So if you have for example a bass guitar and kick drum playing, the planar will make the separation between them more obvious, but the DD, especially on the EA1000, will have more of that punchy quality to the bass. I especially notice if I'm out walking around or on a bus with the Timeless AE that the bass loses even more of its impact because it gets drowned out by e.g., the bus engine noise & vibrations. Whereas on my DD IEMs, the bass continues to cut through any background sounds. On the planars it sounds almost like the tuning has changed, but with the DD it doesn't. In terms of bass quality overall, the EA1000 is definitely better & more realistic sounding for acoustic music. The deeper rumbly sub-bass on the Timeless can be better for some electronic music. Most recording don't have much sub-bass at all. I would imagine that the bass performance of the ET142 will be fairly similar to other planars like the Timeless, the S12 Pro and Artti T10, as it's the same sort of driver and these effects are pretty similar for all of them.

Overall, Simgot EA1000. Partly because it resolves about as well as any of my planars. But lately I have been mainly listening to my Ikko OH300, which cost about $40. Sadly looks like it might be discontinued, because it disappeared from Aliexpress a couple of weeks ago.

It's very well regarded. Some reviewers slightly prefer the Tanchjim Origin, but I skipped that one because some other reviewers say it's more of a downgrade or sidegrade from the Oxygen, which I already have. The EA1000 is definitely in another league technically when you compare it to 1DDs like the EA500LM, Kato, Oxygen, Dunu Falcon Ultra, etc. Even the reviewers who prefer the tuning of one of the other 1DDs acknowledge that the EA1000 is ahead on technicalities. The Origin is the only one out of that list I haven't been able to hear and compare myself. I also haven't heard the stupidly high end ones like the SoftEars Twilight, but that one interests me, to hopefully try in the future. Oh also I keep forgetting that technically the EA1000 isn't actually a 1DD, it's more like a 1.5DD because it has a passive radiator. Most people group it together with the rest though and it's unclear if the passive radiator actually contributes anything. I think it *might* because the bass on the EA1000 is pretty unique too. If I had to pick from the ones that are true 1DDs, in terms of enjoyment I'd rank them OH300 > Dunu Titan S > Kato > Oxygen, but in terms of "technically-the-best" it goes Oxygen -(tiny difference)-> Kato -(big difference)-> Dunu Titan S -(big difference)-> OH300. Also worth calling out the QKZ HBB for being stupidly good for what it costs (about $15). It's roughly my #3 favourite IEM at any price, but maybe drops down to #4 because of the OH300 (I haven't decided if the OH300 completely replaces the S08 or not). The HBB is just very unique for it's super laid back, warm tuning, so I can't see it ever leaving my collection.

The L2 handles metal pretty well. It has good separation & doesn't get muddled with busy parts. Bass is clean & punchy. Cymbals and hi-hats are well resolved but not pushed forward to where they could get fatiguing (like on the S12 Pro). The Simgot EA1000 is the best IEM I've found for metal. The L2 isn't quite as dynamic or resolving as that, but for being very neutral (and a lot cheaper) it keeps up pretty well.

They are bright. Very bright. So if you're at all treble sensitive, avoid. OTOH, if you're not treble sensitive or don't mind the risk of treble-fatigue, they're absolutely one of the best IEMs under $200. Absolutely insane performance for the price. They're basically a mini-EA1000 (my favourite IEM btw) but the EA1000 has slightly more realistic-sounding bass and smoother, less harsh treble. It's still bright-leaning but it's not outright bright like the EA500 and I don't find it fatiguing at all. Because of the extra treble, the EA500 actually has very slightly sharper imaging and a bigger soundstage than even the EA1000, which is known for it's very expansive soundstage by IEM standards. Most reviewers seem to agree on this, despite soundstage in IEMs being a very subjective psychoacoustic effect. You'll be hard-pressed to find a more open-sounding IEM than the EA500, especially not at the price. Keep an eye out for sales on Aliexpress. When the LM came out (not as good IMO but it's a *safer* choice, because the extra bass makes it sound less harsh to most people), there were some pretty big discounts on the OG. I thought they were planning to discontinue it, but it looks like they decided to just keep on selling it. I wouldn't be surprised if it's more popular than the LM in Asian markets, where they tend to prefer a brighter signature. Last couple of times I looked it wasn't as heavily discounted as it was just after the LM came out, but you should still expect to see some decent offers in the many & frequent Aliexpress sales.

That's interesting, I've been curious about those for a while. Maybe at some point in the future I'll be able to track down a lightly used pair to see if I get the same effect and if it's a huge jump up from my current best. I get that sort of effect from the Simgot EA1000 (which we talked about recently). That sort of thing is very recording-dependent though. One that I find is quite good is the Dire Straits live at the Hammersmith Odeon 1983, especially [Tunnel of Love](https://www.youtube.com/watch?v=-3jw0Fjp_fU). Partly for how good the recording of the band is, and also because the crowd sound actually image properly instead of just adding a load of clipped white noise that ruins the recording. Harry Belafonte live at Carnegie Hall is pretty good too, although musically, I'd rather listen to Mark Knopfler. I also get that same effect to a slightly lesser extent but also with an added "bass blanket" effect and more emphasis on depth/layering in a slightly narrower stage from the Ikko OH300, which is $40. And an even more intimate version from the Letshuoer S08. I used to list the EA1000 and the S08 as my 2 favourite IEMs because of the contrast: the EA1000 is like standing on stage, 2m from the band and the S08 is like being trapped in a cupboard with the band, with the singer 2cm in front of your nose. The OH300 has mostly taken over the #2 spot from the S08 in my rotation, but it doesn't have that same trapped-in-a-cupboard presentation (it's very similar in a lot of ways though). The thing about imaging/soundstage is that it's mostly faked in production, hence the huge variation between tracks. Live recordings are usually mult-miked rather than binaural, but the positioning is less fictional because it pretty much has to reflect where the musicians actually were on the stage at the time. Especially if they're moving around between different mics. And then you have things like [Amber Rubarth, Sessions from the 17th Ward](https://www.youtube.com/watch?v=rLgTaL-Q6Ig&list=PL0emVwtw4R9VbtzcZrkMkwXxqPABo9zfE), which is just cheating. It's a fully binaural recording and sounds holographic on just about anything that doesn't have completely whack channel balance, maybe with some slight variation depending on how well that particular headphone/IEM matches your HRTF. Have you got any good recordings you suggest for that sort of holographic imaging? Anything in particular that stood out on the Andromedas? Especially anything that sounds holographic on them but doesn't on other things? I'm always looking for good soundstage/imaging test tracks, that really show off the good stuff and show up the bad stuff.

Yeah, sorry about that one. I do find it far too bright unless I use Spifit CP-100+ tips, but those bring it down to the right level for me, so that my OG sounds fairly neutral and my 2025 sounds mildly v-shaped. I guess tip-related fixes don't necessarily translate well from person to person. But it's likely that you're more treble-sensitive than me too. I don't think I'm the most treble-insensitive person either. I definitely find the S12 Pro and EA500 fatiguing, and I find the Aful Explorer very sibilant, which a lot of people don't seem to notice (probably to do with the amount of 5-6kHz it has relative to the rest of the mids). Hence, definitely don't go buying an EA1000 at full price, there's clearly a big risk you'll find it much brighter than I do. I'm also using Divinus Velvet tips on mine, which are relatively trebly compared to many tips, so if it's just on the edge there you could almost certainly bring the treble levels down with the right tips. Maybe KB07, Dunu Candy or something like that. Maybe even Final Type E black, but I find they remove so much treble they usually kill a lot of technicalities.

Simgot EA1000. Keeps up with my planars for resolution, but with more natural timbre. Also has exceptionally realistic sounding bass when it comes to reproducing things like acoustic drums. Haven't heard anything that touches them for that, including over-ears. Hifiman Edition XS comes close in terms of overall clarity and bass extension, but lacks some of the punch.

The Simgot metal 1DDs are all very comfortable. You have the EA500LM for a balanced, but somewhat aggressive v-shape, the original EA500 that's very bright and gets fatiguing quickly, but it probably has the biggest wow factor for the price. And the EA1000 might be just in your budget depending on sales/offers and is sort of a more refined EA500 that isn't as bright or fatiguing. The EA1000 is my overall favourite IEM, but the EA500LM is possibly a safer option for more people as it's the bassiest one, and although it also has more treble than the OG EA500, it's more balanced out by the bass and it doesn't sound as bright. The other notably good 1DDs are the Tanchjim ones, but their ergonomics are terrible. They're small, but have very bad fit stability. Also the Moondrop Kato, if you can find one, is a great all-rounder 1DD and very comfortable. But it's discontinued. The Kefine Delci is really comfortable, but it's a warm, laid back sort of tuning that's not really competitive with the $100+ stuff when it comes to resolution etc. If detail is your top priority, you aren't going to beat the EA1000. Also while it doesn't have as much bass as the EA500LM, it has more "kick" to it than any other IEM I've heard, and it is very *realistic* sounding bass, especially for acoustic drums.

edit : bought a simgot ea1000 instead. it is perfect for me exactly what i want. got it for 125$ ish, almost pulled the trigger for the supermix 4 but glad i didnt. Anyways since im not gatekeeping anymore, these prices are from carousell

carousell Malaysia. goated app i got the simgot ea1000 instead for 125$. sound quality is crazy good

I listen to a good amount of classical (less opera these days) - lately a bit of mahler, bach, brahms....and I love my Simgot EA1000.

I really love my Simgot EA1000s with the gold filter and some wideboar tips. there's so much detail, and the bass is tight but present.

you're looking at them. same colorway too. I go back and forth between the hype 4s and the EA1000s

Hi everyone, I am once again debating on what I should buy. I'm thinking of getting a planar next, but for some reason I can't get over the thought of getting the EA1000 Fermat. For the planars though, the other two were just my first options. Feel free to recommend anything you like on this price range, I can tell you that I liked a couple of lower range planars and I actually liked them, I have the Aful P5 and I wasn't impressed at all, and I also have my favourite pair atm, the Simgot EA500LM modified with foam. Thanks in advance!

Wow, thank you for taking the time to write all of that. I think the EA1000 has the potential to be my favourite as well, that's why every time I see them, I wanna buy them. I just like Simgot's tuning overall. Yeah, it has a little peak there at 13k-ish Hz, looks very interesting. That was my first thought about Timeless II, why bother making something so similar? Ok, the planar driver is slightly bigger, wow. Although I must admit I'm a big fan of the new design. Never listened to the OG EA500, but I feel ya, that's why I bought the mod kit and changed to a finer mesh on the gold nozzles. I really like them after that. I might like that tuning tbh, I didn't like the Aful P5 that everyone praises exactly because it's too warm and relaxed. I'm considering the ET142 because I love Simgot and I want to widen my collection by getting planars, just to have a little more variety and experiment with other tech. Looking at the graphic though, that lower treble looks very interesting, but the EA1000 might sound better and more detailed exactly because of 11kHz-13kHz: they are opposites in this, ET142 has a big dip, and the Fermat have a peak. I can't decide, I might just pick one randomly and return it if I don't like it. So, what you suggest is: EA1000 > ET142 > Timeless II?

Funny that a few hours ago someone asked me for cheaper recommendations that sound similar to the holographic effect of campfire solaris and I told them I get that feeling of campfires from simgot ea1000.

Can't help you, sorry. It's not really my type of tuning and not being a reviewer, I haven't listened to most Iems (I don't want to make recommendations based on other people reviews as it often happens around here). I'll only say that I've been in the hobby for a long time and the Simgot EA1000 is my all-time favourite (also highest rated Iem on Headfi on average score). Even above Tea Pro, Fiio FH9 and a few other hyped Iems.

This and (mostly) crin's sub has a lot of younger folks looking for sub $50 recs and I can't really blame them, if not for the fact that most game sound engines are not that good that you'd notice any real difference I can directly compare my Cantor, Doscinco, Ea1000 and Arias and all I can hear is "hmm yes the sound is slightly more sound-ier on the Cantor" but I barely play any competitive FPSes since cs2 playerbase is shrinking in Asia and valorant has a particularly bad sound engine You're not going to hear notable differences unless you're getting a soundstage monster like the HD800s or just speakers lads, but it'll probably be a great investment for any other use case
