Simgot EA1000 “Fermat”
Intro
Finally! Finally, I am able to review one of the best iems that Simgot has released to date… the Simgot EA1000. I’ve had such a rigorous schedule of reviews over the past two months which put the EA1000 on the back burner for a little while. However, here we are… and here it is. I simply cannot listen to this set daily and not give my impressions. Whether anyone reads them or not. This is five months of enjoyment which writes the words in this review. I did go back and forth about even conducting a review since it is so far past the release date, but that feeling dies everytime I put the EA1000 in my ears. I just want to talk about it. Yes, this will be one of those reviews. No hype here friends, just pure audio joy from a sucker for things that sound good. The Simgot EA1000 is a set that’s been out for roughly about five to six months now and so I am clearly past the hype period. Of course, I feel that the community has clearly accepted the EA1000 as one of, if not thee… best single DDs under $300. The Tanchjim Origin (Origin Review) may have something to say about that but still, certainly we’ve established that the hype is legit.
Simgot
Folks, the audio brand Simgot has been on a tear like no other. There is no other brand that has erupted like Simgot. They were at one point (not long ago) in the grips of relative obscurity, washed up, no longer a player on the scene. Questions like “what happened to Simgot?” would flutter around from time to time. Never completely gone as Simgot had a few sets floating around the Audioverse, but for the most part they were out of the picture. Then out of nowhere Simgot created a spark. That spark slowly grew. Reviewers began giving good reviews and positive thoughts about the brand with releases like the Simgot EA2000 and EN1000. In my opinion, it wasn’t until the release of the Simgot EA500 that a small spark erupted into something closer resembling a blow torch across a field of dry brush. Now it’s all green lights for this brand. One hit after another. The turnaround is remarkable and it is good for the hobby.
EA1000
The EA1000 is somehow directly connected to Pierre de Fermat, the mathematician who is famous for his mathematical theory. Including what’s known as “Fermat’s last theorem”. Finally proven 350 years after his death in 1995. Countless great minds spent their lives trying to prove it. You can read about that if you’d like but I am not going to break down what his contribution to mathematics has meant to society. What I am trying to figure out is how this great man’s contribution relates to the EA1000. I suppose it’s simply a tribute. Which is fine.
Anyways, the EA1000 “Fermat” is marginally harder to qualify as an actual single DD. I say that because Simgot also used a passive radiator which… isn’t necessarily a “driver” per se. It simply helps the EA1000 in producing the target sound that Simgot so wonderfully sculpted on the Fermat EA1000 (more on that later). At any rate I consider it a single dynamic driver earphone. So, it’s settled with me, single DD. The EA1000 also makes use of tuning nozzles. On top of that, it’s arguably the most gorgeous iem in its price point. I did say “arguably”. Again, the Tanchjim Origin may have a thing or two to say about that. So, there is a lot to talk about and go over. Let’s get into it. The Simgot EA1000 everyone…

Packaging / Accessories
Unboxing
The EA1000 arrived at my home in an average sized box. Purple-is in color and totally class from beginning to end. On the front of the outer cover says the words, “Fermat’s last theorem” with some of the driver tech as well. It’s neat, but we care about what’s inside. Slip the internal box out and you’ll see the same writing on a slim cardboard sheet held back by a cardboard tab. Open the sheet and you’ll see a cool pop-up card with Fermat’s likeness imposed on the front as well as a short synopsis of his life and what it’s meant to modern society. Lift that layer off and you see the beautiful EA1000 sitting comfortably in cardboard covered foam cut-outs. Next to the EA1000 is the box which holds the carrying case. Next to that box are the accessories which come with the EA1000. You’ll find the other two tuning nozzles, tips and cable there. I realize I really don’t do a lot of justice to the actual unboxing, but I can assure you it’s a decent one.
Eartips
Simgot provides six pairs of eartips (L,L,M,M,S,S) of the same style and they are all sitting in a cardboard holder of sorts. The included tips look like a cheaper version of the KBear 07 tips but with a much flimsier flange. They are white silicone tips, semi-wide bore, black and rigid stem and they don’t seal in my ears… at all. The outer flanges are simply too flimsy, they just don’t work. I actually went with my tried-and-true KBear 07 large size tips which seal every time and actually work nicely paired with the EA1000. I went through what felt like hundreds of tips just to resort to the 07’s. Which is a normal progression for me. I’m sure the included tips will be good for someone, but not for me.
Carrying case
The carrying case is gorgeous. It is a gray colored case layered in faux leather, soft to the touch, felt layered foam inside. Very nice. You’ll see the Simgot logo on the top and the nice-looking stitching around the sides. It’s a dope looking case folks! Pure class! This case opens on the top and is held shut with a strong enough magnet. I would say that the case is large enough for the EA1000’s, the cable and maybe a very small dongle dac. It’s not huge but it’s good for putting in a bag and not having to worry about your earphones getting destroyed. I don’t actually use cases ever, but if I did, I’d be happy with this one. It’s a nice addition.
Tuning nozzles
Like I stated earlier, the Simgot EA1000 comes with three tuning nozzles which will slightly alter the sound of this set. Simgot provided a stainless-steel block with threaded holes where each nozzle can screw into for safe keeping. Basically, with these nozzles you are getting three variations of the same target tuning. Two of the nozzles have a damping material (mesh or foam) which does slightly attenuate the upper midrange as well as add a dB or two of bass emphasis. The nozzles come in red, black, & gold. I like each of them but for review purposes I went with the gold nozzle. Here is a very quick breakdown of those nozzles:
Black Nozzle (Stainless nozzle w/ black gasket)
“Simgot Classic target curve”:
The black nozzle has tuning foam inside of it which oddly enough gives the smallest spike to the treble region as well as adds a hint of sub-bass density (barely perceptible). You also get an upper mid spike with this nozzle which is not needed with this set. The stage seems less tall with this nozzle for whatever reason. The black nozzle has the sharpest treble region and it’s the most veiled of the three.
Red Nozzle (Stainless nozzle w/red gasket):
“Harman 2019”
The red nozzle is the one which comes with the EA1000 out of the box. This nozzle sounds very similar to the black nozzle yet instead of the foam it appears to be foam/mesh contribution. The midrange comes across less articulate, less open and airy and thinnest as far as note weight is concerned with a slightly less detailed sound using this nozzle.
Gold Nozzle (copper or gold colored):
“Simgot Golden 2023 target curve”
The gold nozzle is actually a copper nozzle and happens to be the nozzle of my choice. The reason being the overall technical performance isn’t hindered by mesh or foam and the sound is the most open and detailed. I do hear less bass emphasis but also a more subdued treble range to a slight degree. This is definitely the most balanced and neutral sounding of the three with the best staging and it’s the most holographic sounding to my ears.
Detachable Nozzles
Simgot Promotional
The EA1000 features a threaded, interchangeable nozzle design, offering endless possibilities for sound customization. It comes with three meticulously crafted nozzles: one brass and two stainless steel. These nozzles, each with its unique tuning philosophy and approach, allow users to switch between 3 different tuning styles, expanding the headphone’s adaptability and catering to different sonic preferences.
Cable
The included cable is a nice wire. Granted, I really wish that Simgot would have the foresight to add a 4.4 option. So of course I had to cable swap for my balanced sources. Anyways, the cable provided is advertised as a high purity silver plated OFC (Oxygen Free Copper) cable. Of course, it is a 2-pin 0.78 cable which ends with a 3.5 single ended jack. I honestly feel that the included cable is quite nice. The coloring matches the EA1000 very well aesthetically and and creates good synergy with the EA1000 too. During all of my 3.5 single ended listening I used the included cable and felt that it was very nice. No microphonics, pliable and soft enough, not too heavy and it is pretty fat. I love me a thicky-thicc cable ya’ll. However, for any balanced listening I actually chose two cables that I swapped at times. Those being a 4.4 balanced FSIjiangyi copper cable and oddly enough a FSIjiangyi balanced SPC cable which I feel are both absolutely perfect for the EA1000. Truly, folks check out these cables. They are beautiful and elegant and made of the best materials, and they aren’t ultra expensive. Still, at the end of the day you’ll be very happy with the included cable.
Build / Design / Internals / Fit
Build Quality
As far as the actual build quality, structural integrity, and good ole durability is concerned; the Simgot EA1000 is almost in a class by itself. Especially in that +$200 range of single dynamic driver earphones. Again, the Tanchjim Origin may give the EA1000 a run for its money, but wow is this set built well. The Shells are made completely out of highly polished alloy (I don’t know what kind, stainless steel?). This is not a large set of earphones, but Simgot found it necessary to add in a dual cavity structure. You’ll also notice on the bottom side of the earphones is the passive radiator’s speaker cavity (more on the PR next). Simgot chose to make the inside of the acoustic cavity somewhat rough, and coarse which does help suppress some standing waves. The faceplates are made entirely of what appears to be glass. Though in Simgot’s promotional material it only states that it’s a clear crystal. You’ll notice that from front to back, Simgot chose to go all-out and really crafted a well-built iem.
Design
I absolutely love this design. Something so elegant is rarely seen in this hobby. However, Simgot seems to do so in every release. Look at the EW200, the EA500, the EA500LM, and I could keep going. Simgot designs their earphones wonderfully. Just Look at the high polished alloy, like a mirror at all times. Look at the glass faceplates and the white backdrop with the barely perceptible design which surrounds Simgot’s dope looking logo. Also, look at the bronze-colored trim which surrounds the glass faceplate. What a gorgeous iem. Truly a fantastic job Simgot. This is a set that screams elegance. With the subtle touches that could only be dreamed up by a team of imaginative and talented individuals. I think you’ll like it.
All-Metal Body High Transparency Crystal Panel
Simgot Promotional
The EA1000 is the epitome of audio excellence, combining artistry and engineering in one extraordinary package. Its all-metal body exudes durability and sophistication, making a statement of premium craftsmanship.
Internals
Another huge benefit of the EA1000 is the very talented driver inside. It is said that the driver inside took three years of development to finally get right. It is a 2nd generation 10mm SDPGD driver. Its full name is actually “SDPGD multi-layer sputter deposition purple gold diaphragm. That’s a mouthful. Simgot also added a passive radiator to help with extra resonance during Once the SDPGD driver vibrates due to the over 1 tesla force, the pressure and airflow makes the 6mm passive radiator vibrate as well producing small vibrations and reflections.
1DD+1PR Acoustic Architecture
Simgot Promotional
Building upon EA2000’s success, the EA1000 utilizes a 10mm Dynamic Driver (DD) paired with Passive Radiator (PR) configuration. This innovative design enhances low-frequency texture and ambient dispersion. The interaction between the Purple-Gold Diaphragm and the airflow in the rear cavity generates subtle vibrations and reflections, fine-tuning the bass and adding a natural ambiance.
Fit
The fit is pretty nice for me, though I’ve heard some folks having issues. Obviously, anything I tell you about the fit is going to be highly subjective and personal to me. It does take making sure that you find tips which work for your ears. For me the shape and size are great as I’ve never had a moment of bad fit with the EA1000 in my ears. What that means to you, I don’t know. Truthfully, even adding this section in my review is a little ridiculous. Also, for the most part isolation is pretty good. About average. If you have a good seal with good tips then the passive noise isolation isn’t bad at all.
Drivability
The Simgot EA1000 is a very sensitive iem which can certainly be driven off of almost anything. Rated at 16 ohms of impedance and a sensitivity of 127 db’s (give or take) the EA1000 was easily driven from even my iPad. Having said that, I can also say with complete conviction that the EA1000 wants and desires more output power from your source. Basically, most any dongle dac with at least 100 mw @16 ohms will be more than enough. Any more is simply icing on the cake. I actually listened quite a bit on the IFi Go Blu on both 3.5 se and 4.4 balanced and I certainly enjoyed balanced more. That’s a gifted little device and pairs perfectly with the EA1000.
Mobile Listening
Yes, the Go Blu worked like a charm over Bluetooth, but once I attached it to one of my dongle dacs over 4.4 is when the EA1000 really begins to shine. I found the Aful SnowyNight to be the perfect companion with the EA1000, especially on high gain. I had a similar reaction with the EPZ TP50 as well, but it was also the slightest bit more technical. However, listening with the Simgot Dew4x was also a sweet combo. Really a very good pairing with the EA1000. Who da’ thunk it? Now, the EA1000 adapts to different source tonalities very well. Whether I was listening on a warmer dongle like the EPZ TP20 Pro, or an almost dead neutral and sparkly source like the Moondrop Dawn 4.4, I found the EA1000 to shine. Almost no matter the source. It’s kind of a chameleon that way. Certainly more-so than other iems.
More juice
Adding even more juice and better fidelity devices will most obviously create a better listening experience. Folks, the Fiio Q15 and the Simgot EA1000 form a pairing that is quite amazing. If I were to choose what my favorite listening was done with it would be those two. However, I spent just as much time with the velvet warm Shanling M6 Ultra as well as the neutral iBasso DX240 and I really can’t find fault with any of them. I use medium to high gain on each as well.
What do you need?
Like I said, the Simgot EA1000 doesn’t actually “need” much. I honestly feel you’ll be good with a simple phone. That said, I feel that anyone who can afford the +$200 EA1000 will also likely have at least a decent Dongle Dac. I could be wrong though. I know that across this vast world of ours are all kinds of financial situations. So, at least a phone, but if you can get a good dongle dac. Heck, the Simgot Dew4x sounds fantastic paired with the EA1000 and sells for $59. So that’s a good option. Anything better than a phone is just icing on the cake and the EA1000 will reward you for it.
Sound Impressions
Note: I want to preface this entire section with the fact that I did burn the EA1000 in for roughly 50 hours before I really began to judge them. Of course, I also didn’t see much of a difference with the EA1000 and so I can probably deduce that they don’t really need much burning in. I listen almost completely using flac or better files which are stored in my devices. The music player app that I primarily use is UAPP (USB Audio Player Pro). However, at times no do use Poweramp as well as Hiby player from time to time for different situations.
Special
Folks, Simgot really knows how to craft and tune earphones that have a nice tonal balance. There’s a dynamic balance that is matched in each 3rd of the mix in a way that marries technical ability and musicality in conjunction with a solid timbre foundation. I am beyond impressed by the ability of the sound engineers, tuners etc. who craft these sets and dial in their sound. My word, look at their budget $40 iem the Simgot EW200 (EW200 Review) for crying out loud. Reviewing it I had to seriously question why in the world Simgot chose to make it so cheap. It is wonderful. Then the EA500 (EA500 Review), the EA500LM (EA500LM Review), and even the Simgot EM6L (EM6L Review). Each one is outstanding in their own right. Each set is made wonderfully and has a signature that is all their own. I haven’t tried any Simgot set above the EA1000 in price for longer than a day, but I can tell you right now that they also sound amazing too. Those being the EN1000 and the EA2000. Unfortunately, I only heard each set for a short period. They obviously always use the best drivers possible and use perfectly shaped housings to exact their respective target tunings. Truly a special brand whom I hope keeps on doing exactly what they have been doing for a long time.
EA1000
The Simgot EA1000 is what I’d refer to as a W-shaped iem, possibly U-shaped as well. However, I lean much more towards the W-shape sound for reasons I’ll explain throughout the review. The midrange is forward enough to make a wonderful balance across the mix with equal emphasis in the bass and treble. The sound comes across as neutral to bright/neutral. However, that brightness is not to a fault. It isn’t forced. It’s perfectly blended into the overall sound in such a way that you almost yearn for more. Now, if you are coming off of a warmer sounding set, I would advise you to wait to judge until you’ve had plenty of time for your brain to adapt. The sound is equal parts smooth and crisp and quite literally dishes out exactly what the EA1000 is given. What you feed it will come out as it should. The timbre is truly special and comes across very clean with wonderful resolution. It seems that the passive radiator actually does aid quite a bit in cleaning up the resonant sound waves bouncing off the internal acoustic cavity. What’s left is a glass lined and contoured sound that is flat-out impressive.
Between the 20’s
Looking at the bass region, the EA1000 has a snappy, tight and impactful low-end which is moderately extended and moderately emphasized. This is not a basshead set. Not even close. The bass is very well detailed and not even hinting at a one-noted style bass. There’re layers to this bass. The midrange is forward with a leaner note structure. However, within that leaner and tighter midrange note structure is a certain density that is obvious to my ears. The mids also are very detailed with awesome resolution. There is a slight shout on the right track but mostly that is kept in check. Still, there is wonderful vibrance and good separation and imaging as well. It just sounds great. The treble is also just as I’ve described the rest of the mix; vibrant, detailed, snappy, contoured, glass-lined and with a great type of lean density. The treble adds a great sense of air and openness with very good extension into the upper treble. All areas of the mix incorporate wonderfully natural timbre without much of any coloration at all. Again, separation of elements on a stage is top class for a single DD and imaging is spot on. What a nice set!
Bass Region
Just because I say that the EA1000 isn’t a basshead set does not in any way mean that the bass is weak either. No sir. The bass is simply balanced across the mix. The dynamic balance is superb on this set with plenty of air between bass notes. This is a textured bass that operates within layers of sound, all of which comes across distinct and precise. I don’t hear any bleed over into the midrange whatsoever which makes for a very precise and resolute midrange. The EA1000 sounds as though more than one driver is operating down low as the sound doesn’t sound flattened or blurred. Every note has a round vividness to it with a low pitch vibrance that creates a certain presence for each note as well. It really is special considering this is a single DD.
Now, the EA1000 is not going to give you those super beefy and warm rumbles down low. You also won’t hear anything that is over the top booming either. It isn’t a traditionally big bass, or even a fun bass. This is a technically adept bass that comes with pin-point control and just enough of an emphasis to my ears. So bassheads, keep looking. But also, those who prefer an even sharper low-end with BA type transients than I’d also say keep looking. The EA1000 forms a perfect middle ground between the two distinctions and honestly… I’m all for it.
Sub-bass
The sub-bass has decent extension into the lowest of lows. Certainly, enough of that low-pitched drone to accommodate most any track. In my opinion the sub-bass takes what it’s given and reproduces that sound right back to the listener. It’s a moderately healthy dose of guttural density that sounds appropriate with the rest of the mix while never seeming over colored. This set is all about balance and the sub-bass doesn’t shy from that. Like I said, the passive radiator does seem to strip some of those unwanted resonances from the final sound before it hits your ears. What you are left with is good texture and a very clean result.
Sub-bass cont…
Now, fans of an ultra-extended and fun sub-bass within this region will likely not be impressed. I wouldn’t say that there’s a roll-off, but there is a bit less amplitude in the lowest of lows. In the track “Mancey” by Andrew Bird I find the deep bass guitar riff to have plenty of depth with a very streamlined rumble and drone which sounds very nice to the ear. It certainly isn’t lacking. What you’ll notice is just how condensed the sound is. There is tactility at the crest of notes that is utterly wonderful. Attack speed at the leading edge is rapid, with a very crisp, defined, and exact point of contact. Decay is not drawn out and is actually fairly quick. Let’s put it this way, decay is as quick as a natural sounding decay can come across, in my opinion. You’ll also notice that the extra resonances and fuzz which would usually be floating around the sound field are not there. I’m attributing that to the passive radiator’s ability to absorb those noises. The sub-bass moves along with nimbleness and dexterity for even complicated tracks while still sounding compact, bodied (weighted), deep enough and very well controlled. No tiny bit of sound is wasted here as all info is relayed straight to the ear and I feel nothing is missed.
Mid-bass
I feel that the mid-bass has a perfect emphasis in conjunction with the sub-bass. For instance, bass guitars have just enough meat to them, as well as fullness without an overbearing sub-bass diluting the texture of most bass guitars. Kick drums are the exact same thing. I hear that very tactile initial hit with good tackiness and vibrance which is followed by a very well structured and defined hollow boom. Perhaps that “hollow boom” won’t be enough for some heavy bass lovers but for me, I feel that all kick-drums sound organic and real to life. What the mid-bass does well is rise to the occasion and I love it.
Mid-bass cont…
This is not a bass that colors the overall sound or adds any veil whatsoever. This is as clean as it gets apart from using different drivers. Of course, BA’s, planars etc. can also come across as unnatural. No sir, Simgot did the mid-bass right and it fits the tuning. The mid-bass hits with very good impact and great low density vibrance that you can feel as well as hear. I feel it’s the texture and fantastic layering which separates this set from others. The mid-bass has wonderful definition with a clean lined, fine lined, and perfectly controlled note presence. It’s really nice. Unless of course you are a bass-boi, at which point you’ve probably already stopped reading this. This is the picture of a mature dynamic driver bass region and is some of the best you can buy for the money. Listening to “Billie Jean” by Weezer (MJ cover), it begins with some hefty and repititous kick-drums. One after the other. Each kick-drums beat is followed closely by a hard snare drum pang. The EA1000 hits with precision. No extra fluttering noises cramping the note definition. The hit feels tacky with a tight boom and a quick release followed by an exclamation point style snare hit. Again, one after the other. Or “Can’t Make Up My Mind” by Cmat. The EA1000 does so well as separating her slick vocals while simultaneously showing off its ability to take on a heavy bass guitar as well as consecutive drumbeats. It’s all so clean folks. Just wonderful.
Downsides to the Bass Region
The only downside would be for bassheads. That’s it. Okay, maybe I would say that there are some folks who enjoy a more atmospheric decay. I’m reaching though. Well, I suppose that some folks may want a bit more push into the midrange with the mid-bass so as to offer warmer male vocals and a slightly warmer approach altogether. I could see that. However, beyond that I find the bass region to be awesome and I also feel that Simgot really outdid themselves here. Nice work Simgot!
Midrange
The midrange has a natural timbre, brighter in vibrance as well as overall energy which comes across as more rambunctious macro-dynamics. Note weight has that nice lean-lush or rangy type reminding me of lean-muscle-mass with no extra layers of fat to the sound. The midrange instrumentation is well separated with very good imaging boasting a very well layered approach. This is not your warm, lush, smooth type of timbre. The EA1000 is exuberant but yet pinpoint in almost all ways. Its forward sprightly energy and fast decay can be somewhat polarizing, in that… not everyone is going to be a fan of this style. This wide open and airy style of midrange comes across crisp, and knife edged with a glass lined note outline which will likely rub some the wrong way. You don’t get that smearing of the sound field within the midrange as it is always clean as a whistle, high definition and always high resolution. However, I also don’t hear that dry and analytical timbre all the time either. Though the note weight isn’t thick and overtly weighted, it still has a density which I feel has to do with the cleanliness of the sound and the hard-edged impact and transparency of each well-defined note. I don’t hear a frail, weak, dry or papery sound here. There’s moisture to it but in a compact form. If that makes sense.
Lower-midrange
The low-mids are the primary frequency where males reside, some of the time anyways. Obviously, this isn’t always the case. Anyways, the males on the EA1000 are nice sounding, more forward than other sets and very much unsullied, with a very high resolution. Males have a very good presence. This isn’t that thickly weighted and slower style male vocal but instead it carries a very nice crisp edge for male voices. However, I don’t feel that the EA1000 exaggerates already sharp and edgy voices. Instead, the EA1000 simply defines them further, more crystalline, and without the abrasive edge that can be heard with lesser drivers and lesser tuning.
For instance, Stephen Wilson Jr. has that edge to his voice that I’m talking about in the track “Year to be Young 1994”. It’s raspy but sharp. To me he has this coarse, jagged and melodiously unpolished voice that can get absolutely derailed on a lesser set. The EA1000 doesn’t intensify the gritty and unfinished style or add any undue grain fuzz to his vocal rendering. Instead, it comes across as simply higher def. but with very nice separation against the thrumming bass backdrop. Also, voices like Dermot Kennedy in his track “Rome”, the EA1000 shows off his voice very well with nice forwardness yet still only slightly more forward than the Instrumentation. He really does sound nice. Of course, that is if this leaner and more energetic sound is something that you’d enjoy. I can get with it just fine and actually really enjoy the natural/bright hue to the spectrum.
Upper-Midrange
Now, females are also simply a bit more forward, more vibrant, more energetically structured but with almost perfect resolution. No instrument goes unnoticed and every breath, every sigh, every inflection of a woman’s voice is captured in wonderful HD quality. You’d think that this vibrance I speak of would come across as wholly unnatural. I know I would. Usually, brightness in this region tends to skew the timbre and force some metallic texture or thin it out too much. That really is not the case. Also, when I say “bright”, what I mean is simply more aglow and heightened with slightly off-natural luminance. It’s tastefully done on the EA1000. However, this region can become shouty and too energetic to those who aren’t prepared for it. So, I would still say that the EA1000 is surely a set to make sure the signature fits your criteria of what “good” sounds like. To me, the upper midrange takes me right to the peak of my tolerance and stays comfortably controlled inside what I would consider as… “too much”. Females take on this slightly more elated sheen.
Upper-mids cont…
Listening to Caitlyn Smith in the track “High”, I am captivated at the wonderful resolution which holds tight to note integrity by softly feathering through the main verse with very nicely separated instruments and carefully tended vocals. Caitlyn’s voice goes from softly sweet and feathery to absolutely resounding within the chorus. Perhaps for some, this chorus will be a bit too biting. Not for me. Also, the chorus is one that will blurry and blend most sets with all of the chaos happening around her. Not with the EA1000. The notes here are crisp but not edged in abrasiveness, much like the rest of the spectrum. Notes have good solidity even in their leaner body and each instrument has more than enough room and space to operate.
Instruments
One of the EA1000’s best strengths are in its resolving and transparent nature. I hear this daily in most any track as instruments come across very well layered behind the vocalist. Most percussion has a clangorous and very tight snap to them. Snares have that pointed energy to them which is completely satisfying. The fundamental tones of a cymbal strike are a hint thinner than some sets, but they also aren’t frail sounding. There’s a fine line there that not many single DD sets in the price point can duplicate with this much clean transparency. Strings have a good bite with that nice sharp edge to them. Acoustic guitars, banjo, mandolin, etc. They all sound natural but with some added zest. Violin sounds melodious enough, silvery at times and tuneful at others. Piano may not have the fullness that some may always enjoy but every note is so clean which sounds peppy and almost kinetic in its 3d type of soft enthusiasm. Again, there is vibrance, but also good and solid structure in that vibrance. Not the easiest thing to explain actually. Beyond these, just picture any instrument and add some soft intensity and dynamism.
Downsides to the Midrange
The midrange will either be loved or looked down upon. As with any set. However, the EA1000 most certainly has that polarizing quality to it. Without question, if you love a thickly weighted and warm type sound that is smooth through and through, then the EA1000 may not be the set for you. Not everyone enjoys this type of replay. Many folks prefer musicality over a more analytical approach. Now, the EA1000 isn’t without musicality, but it is certainly more technical than anything. Yes, the transients are very tightly reigned in with exact definition on most every track, but sometimes folks want that emotional replay and the EA1000 will not always give you that in a smooth and warm way. However, I cannot sing it’s praises enough. I’ve loved this set since day one. If you’ve followed me at all than you’ll know that I usually have to warm up to a set. The EA1000 just has that “thing”, the “it” factor. I don’t hear any sibilance and I don’t hear a simple and flat plane of music in front of me. It’s textured in every note with distinct layers which makes for a great listening session.
Treble Region
The treble region would usually be a slight point of Contention for me when listening to a single DD. This is not the case at all with the EA1000. The treble happens to be one of the main contributing factors that creates the awesome clarity in the overall sound. The treble has a very nice emphasis which balances nicely with the rest of the mix. You’ll hear a nicely brilliant treble that brings on heightened levity to the whole of the sound. I love the level of treble that Simgot saw fit to tune the EA1000 with. Honestly, the treble almost sounds like a hybrid type sound to my ears. Truthfully, the treble is one of the highlights of the EA1000, which is radical to me. It almost comes across with a BC-like haptic recognition in many of the more dynamic notes. With that said, I still don’t hear those ultra glaring and sharp ear gouging treble peaks as I usually do on sets with forced resolution and treble emphasis. The EA1000 offers actual tactile and contoured bite to every note up top.
Treble cont…
I hear a very nice transition from the pinna gain in the upper midrange working smoothly into the lower treble. There is such a clear and structured refulgence within the presence region that is very well highlighted, adding a fun and nicely detailed treble that never seems to over saturate the mix. You really don’t see this all too often in single dynamic driver earphones. Beyond that nice transition from the pinna gain, I also love the extension into the upper treble. There is plenty of information past 10k which actually is a bit refulgent itself. However, just because it’s brilliant and has a certain shine to it, doesn’t mean that stuff like the secondary harmonics of a cymbal strike come across sheen out in treble tizz. They don’t sound splashy to me. You still have that controlled timbre even at the extremities up top in the air region.
For what it is… It’s good
This is a highly detailed and highly resolving treble that doesn’t shy away and take the easy listening route. The EA1000 forces you to pay attention to all the subtleties within your music. I don’t feel that the uplifted brilliance is necessarily so boosted that you lose that definition, which is something I listen for, especially as a treble boosted iem. This also isn’t necessarily an analytical approach either. Believe it or not. It isn’t so thinned-out or dry that you lose body within treble notes, kind of like blurred instrument separation from treble sheen and gloss which will flatten notes up top at times. The EA1000 still has a certain roundness and euphonic presence up top which has actual layers to the sound. I wouldn’t say it’s like a good est style treble, but for what it is… it’s good.
The EA1000 also has a speedy treble region which can take even the fastest and more complex treble passages and replay them with relative ease. The cadence is so on point with this set. Listening to Billy Strings in the track “Secrets”, or really any track by Billy Strings. Anyways, the EA1000 quite literally takes the lightning quick and congested banjo play and compartmentalizes each note and instrument with actual clean separation. Or “Bishop School” by Yusef Lateef. This is a track with a litany of treble activity that never stops and the EA1000 takes this poorly recorded jam and replays it succinctly and with good resolution. Honestly, it’s hard to really spot any huge issues up top but I’ll try to do just that…
Downsides to the Treble Region
I would say that many folks only enjoy a more rolled-off treble region. I have friends who much more enjoy a warm, or even dark treble. They don’t want the brilliance and for those people I would probably tell you to keep walking and pass up this set. Beyond that, I cannot find any other glaring subjective gripes that some folks would have. I even think that treble junkies may like this set a bit more than most that I’ve reviewed lately. The treble fits the overall sound so very well and adds so much to the sound. It adds that last little bit of zestiness to the midrange and is very well detailed.
Technicalities
Soundstage
The soundstage has good depth of field and layering from front to back. The stage creates almost a psycho-acoustic style depth which is great to hear on a single DD. The width is roughly average to above average. Nothing colossal in width. Still pretty darn good. Height is also average as well. The stage as a whole is slightly pushed back with the center of the sound field not as up front and in your face as some sets lately. Also, when I say average, I mean… it’s good. This is not a bad thing. No, bad would be the stage feeling cramped and congested or narrow, with elements of the stage seemingly blending together. I can assure you that the EA1000 doesn’t have that. It also helps that you have an airiness to the sound which seems to almost exaggerate the openness and overall stage size in a 3D-like way.
Separation / Imaging
Separation of elements within an imaginary stage is excellent on the EA1000. I feel like I’ve covered this multiple times already in this review, but it bears repeating. The Simgot EA1000 has very good control over the mix, simple as that. You have a fast and tight transient response, an open and airy replay across the board. You have that lean but solid note construction with clean-lined resolution. On top of that the overall signature is very well balanced without any frequency oversaturating the mix and masking anything. This all helps the EA1000 to come across very well separated. Obviously, there are sets with multiple drivers which can separate a hair better, but those usually will also have other issues too. You won’t have that single DD timbre and spectrum conformity, cohesive from the bass to the treble. This isn’t always the case with some other driver types. Imaging is honestly just as good in my mind. I feel that I never really have an issue placing instrumentation. Now, I haven’t gamed with this set but for music listening I haven’t heard much that trips up the EA1000. Maybe some ultra complicated music or congested style music. Blaring electric guitars may mask over some tracks but that’s to be expected. It’s all pretty good here.
Detail Retrieval
Detail retrieval is another benefit of owning the EA1000. Just like separation and imaging, there really isn’t much that the EA1000 cannot handle. I feel like I get just about every nuance within my music which is awesome to hear. Especially because the EA1000 is a single dynamic driver earphone. Also, some sets with good detail retrieval will sound way too thin and papery for me. They will come across far too analytical. The EA1000 is somewhat analytical but it also has a penchant for musicality as well. Again, please tell me what musicality is? The sound is clean across the board, well balanced, tight, resolute and you have very good spacing with the EA1000. Add all that up and what you’re left with is a set that will draw out the subtleties very well. Truly you won’t be missing much. I feel the only real caveat would be very poorly recorded music, ultra bass heavy jams and tracks featuring a lot of congested instrumentation that is primarily focused near the upper-mids and lower-treble. Basically, heavy metal with ear gouging electric guitar play. There really sint much that will trip this set up.
Comparison
Note: Some of this comparison is copy pasted from my Origin Review. For obvious reasons. My opinion hasn’t changed on this comparison.
Tanchjim Origin ($259)
Of course, the one comparison that I choose is also one of thee best single DD’s that my ears have heard. That set is the Tanchjim Origin (Origin Review). The Origin has one of Tanchjim’s 5th generation 10 mm DMT5 drivers at the helm as well as some wonderful acoustic structure which helps this set to sound as good as it does. Truly a marvel at its price and the one set that I feel gives the EA1000 a run for its money in every aspect from the design, build, unboxing, and overall sound quality.
Differences
Looking at the build, the EA1000 and the Origin are absolutely built exceptionally. Both sets are as premium as it gets. The Origin is all metal (as you know) and the Simgot EA1000 has a stainless-steel shell and a gorgeous glass faceplate. As far as design, again, how could I choose which is better? Truly they are both as handsome as they come at the price. The EA1000 is a bit more elegant, and the Origin is bolder. Both fantastic. The EA1000 has the better cable, the Origin has a much better case, both sets have decent tips (Origin edges it out), and both have tuning nozzles. Granted, the EA1000’s tuning nozzles actually work. I would say the EA1000 is slightly easier to drive.
Sound Differences
These sets are tuned a slight bit differently from each other. The EA1000 is more of a Harman tuned U-shape to W-shape with a neutral sound, more energetic, more dynamic. The Origin is neutral with the slightest spritzes of warmth and a slightly more poised sound with better note control and more of a balance across the mix. The EA1000 reminds me of a downed electric line sputtering and zapping everywhere, just energy everywhere. The Origin is a hint more organized, streamlined, with more structure to notes. Both sets are very close in so many ways with only slight distinctions that separate them. The EA1000 is again, more dynamic, while the Origin is a hint blander in comparison. Actually “bland” is an awful word. I think “poised” and “structured” say it better. But also, musicality is a bit better on the Origin, depending on your definition of “musical”. The Origin has less vibrance then the EA1000 but also has cleaner note edges than the EA1000 too. Pick your poison although you cannot lose either way.
Between the 20’s
The bass in the EA1000 is deeper by the slightest margin but both have good control in the bass region as well as a tighter sound. Both have a good punch and neither come across soft. Now, the Origin has slightly less impact, but I find both sets have great definition down low. Both sets are also mostly naturally weighted, while the EA1000 sounds a hint more boosted. The midrange of the Origin is closer to the listener, maybe a hair more melodic and better for vocals in my opinion. At one point I would’ve said that details emerge easier on the Origin, but I take that back. Both sets really do an equal job of bringing out the smaller details. Now, out of both sets the EA1000 has more dynamism and is slightly more colored in the upper midrange. No doubt the EA1000 can get slightly shouty at times, whereas the Origin usually keeps a tighter rein on that shout. Timbre wins on the Origin as it’s a bit more lifelike to me which is partially due to the added vibrance of the EA1000. Purely subjective. The truth is, both sets sound truly special as far as timbre is concerned. The Origin also has thicker note weight by a small margin, while the EA1000 is more transient tight and dynamically expressive. The treble of the EA1000 is a hint more boosted and vivacious to the slightly less energetic Origin. Both iems have fantastic treble regions for single DD’s and both are extended well with good detail retrieval. Remember these are the slightest differences, I cannot stress this enough. This is hours of going back and forth.
Technicalities
I feel that the two of these sets are both technically astute and very clean across the mix. Detail retrieval is great on both sets with the Origin having a slight advantage there. Imaging is great on both sets as well as the separating of elements on an imaginary stage. Also, the Origin has a wider stage while the EA1000 has the deeper stage to my ears.
Final thoughts
I hate these comparisons. Mostly because I forget to actually critically listen at times. What can I say… I get lost folks. I truly love both iems. It’s a complete toss-up for me. Really, whatever iem is in my ears… That’s the one I like better. The deciding factor for you may be the more energetic sound of the EA1000, or the more balanced and less vibrant sound of the Origin. Of course, another deciding factor for you may be the fact that the EA1000 is $30 cheaper at $219 rather than $249. Again, I couldn’t really give you a good answer as to which set is better. For me personally, I’d probably go with the Origin if I had a gun to my head. However, I truly adore them both.
Is it worth the asking price?
The question that I always will get in every review is whether the set I’m reviewing is actually worth the price the price to own them. I was asked enough that I decided to simply put this question in my reviews. At any rate, of course the EA1000 is worth the money they are asking! This set is ridiculously good in almost all ways. That said, you do have to actually enjoy the signature that Simgot tuned this set to. Not everyone will be a fan. Believe me, I’ve heard from many folks that the EA1000 does not fit their preferences. Which, by the way, is exactly how it should be. I really do feel that these differences are what makes the audio hobby, the best hobby. We are all so different. However, if you like this type of energetic, balanced, almost analytical sound with great control of the spectrum, and a knack for making your music sound spectacular… then the EA1000 is most certainly worth the $219 to own it.
The Why…
The EA1000 is built with exquisite materials that truly make the design POP. They look more like jewelry than they do an iem at times. Just gorgeous folks. So, the build is great, the design is even better, fitment is also good. Simgot added a very good unboxing experience as well. However, it’s alway comes down to the sound on any iem. I feel the EA1000 is worth the $219 because it replays my library so precisely but yet without excluding musicality. The EA1000 is really a benchmark type set in many ways and should be considered at least in the top three for best single DD iems under $300. My opinion folks.
Heavy hitters
I’ve heard all of the heavy hitters and gotten rid of a lot of those “supposed” heavy hitters. I have the Dunu Falcon Ultra and it is truly a special set for straight up timbre quality & balance, but it ain’t the EA1000. Also, I’ve owned the BQEYZ Wind, no chance for that one. It’s a good set but the timbre simply doesn’t stack up. I had a lot of metallic edged timbre in the upper portions of the mix. Other than that, there was a slight lack in low-end oomph. That one went packing. I’ve owned the Tanchjim Oxygen, own the Tanchjim Hana 21, the Penon Vortex, the Fiio FD5 and many more. The point is, you flat out will not find many that can do what the EA1000 does… better. I feel the only REAL challenger is the Tanchjim Origin. That’s it. Again, this is my opinion, and my opinions are only true to me. So please don’t feel offended. I am not here to do that. So yes, the EA1000 is well worth the asking price, for me.
Ratings (0-10)
Note: all ratings are based upon my subjective judgment. These ratings are garnered against either similarly priced sets or with similar driver implementations or styles with the unique parameters of my choosing. In the case of the Simgot EA1000 ratings below, that would be $150 to $300 single dynamic driver earphones. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an iem what it is. A “5-6” is roughly average and please take into consideration the “lot” of iems these ratings are gathered against. $150 to $300 is a decent sized scope of iems that is extremely competitive. However, it’s also a small enough pool of iems that seeing a “9.0” for example, shouldn’t be too amazing to see. My ratings are never the same and each set of ratings tells a different story. Each time you read one of my ratings will be unique to that review. Basically, I create a Rating that makes sense to me.

Ratings Summary:
Folks, you need to read the fine print above. I get way too many DMs about these ridiculous ratings. They are always nullified and understood when I tell the person… “Did you read the note above the ratings?” almost unanimously the response is “No”. I always outline the parameters of each particular rating. I garner these ratings on what I feel the consumer would be looking for. Remember, these particular ratings are gathered against any single dynamic driver iem between the prices of $150 and $300 (that I’ve personally heard or have in my possession). I have to at least spend enough quality time with these sets to make this judgment. Again, I haven’t heard everything either so please don’t be upset. I’m not here to cause any division about something as ridiculous as earphones. People get really angry over this stuff, which is a bit odd. Moving on…
Explain Yourself!
There really isn’t much to summarize here. I feel that each rating mostly speaks for itself and they are all pretty cut-n-dry. Out of single dynamic driver earphones between the prices of $150 and $300, the Simgot EA1000 is simply one of the best that money can buy. With only one caveat, it has to fit your preferences. I gave the Simgot EA1000 a score of a “9.3” in overall sound. Coincidentally, I also gave the Tanchjim Origin the same exact score. They trade blows back and forth very well for me actually. Just to show you the company that the EA1000 keeps.
As for the ratings above. The EA1000 averaged a very lofty “9.3” and I really don’t feel there are many ratings above that I would argue about. Maybe some would argue that the “bass” rating is a bit too high. I could also see folks criticizing the rating I gave the EA1000 for “musicality”. I don’t think that I would really budge on them, but I understand any disputes. After all, this is a subjective game, friends. It just is, and it always will be. Shoot, the guy next to me may think I’ve lost my mind. I actually expect that. I’ve never liked rating anyways, they can strip away nuance and they don’t really show you the big picture. I said the same in the Origin Review as well.
Conclusion
To conclude my full written review of the Simgot EA1000, I have to thank anyone who chose to stick it out until the end. Thank you for listening to my mindless babble. My greatest hope is that it helps you. At least to some degree anyways. These reviews take a ton of time, a lot of hours listening, and a ton of notes (⅓ of a 50-page notebook). I look at it as a second job that I don’t get paid for. I really give you my exact impressions from many careful hours of listening. So, I say all of that to say thank you for trusting me. It means the world.
Other perspectives
As always, I also have to make sure that I at least try to persuade you to check out other reviews. We want you to get this purchase right and we want it to make sense for both your enjoyment as well as your pocketbook. Like I said earlier, we are all different, and the guy sitting right next to me may feel I’m crazy. Every reviewer is different as well. It would certainly give you an advantage to check out as many thoughts and opinions as possible. With that, I think I’m done. Please take good care, stay as safe as possible and always… God Bless!
