Simgot EA1000 "Fermat" In-Ear Monitor

TLDR version on YouTube: TDLR - Simgot EA1000 "Fermat"

The EA1000 “Fermat” have been sent to me by Simgot in exchange for the publication of my opinions in this review. Simgot have not made any specific requests and I will attempt to be as unbiased as humanly possible in my review.

Intro…

The Simgot EA1000 are by no means a recent release, at least in the terms of IEM releases, which move faster than operating system updates! There are a lot of reviews out there, stretching back to October 2023 and I had already heard some very good things about the EA1000.

As I have said many times in the past, I try to not take much notice of reviews and comments by others when I plan on reviewing something, trying to avoid any expectation biases, but it has been impossible to avoid all mention of these IEMs in the past 6 months or so.

So, while my review may not be as completely free of preconceived expectations, I was still more than interested in trying out the EA1000 when Simgot reached out to offer the chance.

Now this is not the first set of Simgot IEMs that have been across my desk and my opinions of the previous models I have reviewed have been similar across the board, great performers but not my personal taste.

In the case of the EA1000, we again have a similar tuning to some of the previous models I tried from the brand, although with some minor tweaks. Here the choice has been a a single 10mm dynamic driver paired with a 6mm passive radiator, which is located on the inside of the shell facing the ear.

I really don’t need to go into much more as far as specs and background, as there are already many reviews out there that have covered them, so let’s get on with my usual format.



Presentation…

The packaging of the EA1000 consists of a purple outer cover that refers to Fermat’s Last Theorem on the cover. On the back, in the usual Simgot style, we get three frequency graphs that show the tuning of the IEMs with each of the included nozzles. As the side of the graphs it shows what these tunings are targeted as, along with mentioning which nozzles to pick for each of them.

From the side of the cover, an internal black box pulls out that is presented in a way that is nicely different from so many othe presentations. Instead of a lift off lid, there is a top card (that also references Fermat) that lifts forwards in a sort of origami folded fashion and reveals a copper coloured business card showing Fermat's Last Theorem and a QR code on the back that can be scanned to extend the warranty period of the IEMs. There is a lot of other text on this top card layer, such as an explanation of the Theorem, which makes it look elegant and much more to the eye than a simple cover.

Folding this top cover to one side, we are greeted by the IEMs sitting in their respective cutouts at the top. Towards the bottom of the box there are two smaller boxes, one for the storage case and another for accessories. Then, finally, underneath the IEM layer, we find another accessory box inside which there are 6 sets of silicone tips (in 3 sizes, 2 of each) and the user manual.

In total, as far as contents, we get the IEMs, the cable, 6 sets of tips, a storage/transport case, 3 sets of nozzles and plenty of replacement o-rings for the nozzles.

I find the packaging and presentation of the EA1000 to be nice and elegant, making the unboxing experience something a little different to so many other sets. As always, I applaud companies that come up with their own twists on something as simple as packaging, without going overboard and using tons of plastics. In this case, except for the plastic bag containing the o-rings, all the packaging is cardboard and has a nice premium feel to it (as far as cardboard goes of course).



Build and aesthetics…

The shells of the IEMs are completely metal, except for the white faceplate that features a subtle design to the background and the Simgot logo in a coppery rose gold colour. I have to say that I think the IEMs look very elegant and discrete, with just enough going on to stand out.

On the inside of the shell, there is a passive radiator which is covered with a grille that is also a coppery gold colour. There is a metal and and center over the grille where Simgot have opted to put the L and R to identify the size and, once again, I think it is very tastefully done.

The cable is in a matching silver colour, with silver hardware, and just a gold coloured chin slider that is less coppery in colour than the other rose gold accents but still looks good. The cable seems to be of decent quality and I have had no complaints about using it paired with the IEMs. There is no balanced option included but that is not unusual.

The included storage/transport case is also of good quality, in a grey colour with a flip up lid and magnetic closure. Inside the case there is also some elastic on the lid and a pocket on the bottom to serve as organization. The case is plenty big enough to store the IEMs along with any accessories you may need.

As far as comfort, I do find them to be comfortable although I did have issues getting a good seal, even when opting for the largest size of included tips. I did get a seal, just that it took a little more work to get them seated correctly.

As a whole, I find everything to be of good build quality and have elegant aesthetics, so absolutely no complaints from me here.



Sound…

As said a moment ago, there are three sets of nozzles included with the IEMs, each providing a slightly different tuning. The differences between the tunings are not huge but they are very noticeable, enough to prefer one over the other depending on preferences.

While the 2 sets of silver nozzles do have different coloured o-rings, red and black, the set with black o-rings has a foam filter located inside the nozzle, which is why I have referred to “Silver” (the ones with the red o-rings) and “Silver with filter” (the ones with red o-rings). For brevity, I am going to refer to them as G (Gold), SwF (Silver with filter) and S (Silver), throughout the review.

Here is the frequency graph of the 3 tunings in relation to my usual preference target:



As you can see, the differences are not a lot but they are certainly enough to differentiate between them when listening.

While the bass ranges (and mids) are almost identical between the three nozzles, the change in the upper minds and treble is enough to reduce focus on the lower ranges depending on which nozzles are chosen.

So, starting off with the subbass range, and with a focus on “Chameleon”, the G nozzles do rumble but not excessively. There is more of a focus on the midbass here than on the subbass. Moving to the SwF nozzles, there is a more noticeable rumble, even if the graph may not indicate a very noticeable difference in these ranges. This is due to the reduced upper peaks that allow the focus to be placed more on the lower end. With the S nozzles, the rumble is slightly less than the SwF but it is not a huge difference.

Moving over to “No Sanctuary Here”, the midbass with the G nozzles is clean and controlled, with clean hits that are fairly impressive. Swapping over to the SwF nozzles, the midbass is maybe not quite as clean sounding as the G but it is much more enjoyable in general. With the S nozzles, the midbass is slightly tamer sounding than with the SwF but still sounds a little less clean than with the G nozzles. The presentation with the S nozzles is nice but I do find the SwF presentation preferable to my ears.

Testing out the midbass for fatigue, using “Crazy” as always to judge any excessive reverb in the guitars lower notes, I found that with the G nozzles the midbass in not overly boosted and takes a bit of a back seat to the upper mids. It is not fatiguing in the midbass but the upper mids are too present and a little harsh, although not terrible, it is mostly noticeable in the moving of fingers on strings. Here the SwF nozzles give us a midbass that is still not fatiguing, although there is noticeably more presence of the reverb than with the G. Vocals are less harsh but there are still touches of sibilance. With the S nozzles, we are sort of mid way between G and SwF as far as midbass is concerned, although the upper ranges are slightly harsher and with touches of sibilance similar to the G.

“Smooth Operator” is a fairly well produced track and has a decent balance in general but with the G nozzles, I do find it to be lacking a bit of bass presence and warmth to the vocals. With the SwF nozzles there is more presence in the bass and a warmer tonality in general, although vocals do take a slight step backwards. With the S nozzles, we have a similar story as with the G, the track loses some bass presence and warmth in general.

Looking at something a little busier, such as “The Room” by Ostura, the G nozzles do a good job of providing detail and separation of instruments, even with the busier parts of the track. With the SwF, the separation of instruments is not as impressive but the overall sound is much more pleasurable, less thin and more authoritative. With the S nozzles, the detail is more upfront but the track is thinner overall and harsher in its presentation.

Staying with something in a similar genre, “Killing in the Name” does sound a little thin with the G nozzles. Moving to the SwF nozzles, Rage Against The Machine starts to sound like I expect Rage to sound, with more authority to bass and guitars, less harshness and fuller sounding overall. The S nozzles bring a similar experience to the G nozzles, seeming a little thin and, in this case, a bit harsher in the higher guitar notes.

Something a little more acoustical, in this case “Free Fallin’”, I find the G nozzles to be a little thin sounding due to the upper mid forwardness. With the SwF nozzles, the guitar sounds more realistic, with vocals that are not quite as present but smoother and more enjoyable. The S nozzles sound a little more detailed than the SwF, with vocals a little more upfront but not quite as smooth.

Focusing on vocals, male in this case, “These Bones” has nice balance of vocals with the G nozzles although those upper mids remove some warmth from the bass focused vocals. With the SwF nozzles, there is more body to those low vocals, with a more smoothed out presentation. With the S nozzles, things are a little more detail focused but again lose a bit of warmth in those lower vocals.

With female vocals, in this case “Strange Fruit”, the G nozzles provide a good separation of layers but are missing some body to the vocals. The SwF nozzles are not quite as detailed in the nuances but provide more body to the voices and are a preferable, to me, presentation. The layers are not quite as separated but, again to me, it is worth it. The S nozzles bring back more focus to the details but again present us with a harsher experience.

Finally, as a last track I am going to mention as this review seems to be much longer than I anticipated, “La Luna”, a binaural recording. With the G nozzles, the space is decent but there is not a huge amount of depth to the rear. The SwF nozzles presenta a similar story, maybe even slightly more compact, whereas the S nozzles do present themselves as the most spacious of the three, with more depth and better separation of instruments and positioning.



Conclusion…

The Simgot EA1000 “Fermat” is a set of IEMs that aims to give you a lot for a price that, while not the cheapest, is still very fair. We get a nice presentation, an excellent build, decent accessories and good looks.

We also get three different tunings to choose from. While the tunings may not look that different on paper, they are certainly different enough to the ear to clearly pick one as a preference above the others. In my case, my preference lies with the “Silver with filter” nozzles, which, while not focusing on presenting detail as much as the other two, have a slightly rounder and more relaxed sound to them. Now, this is actually surprising to me as, looking at the graph, I would have expected the SwF nozzles to have the harsher presentation of the 3, due to the more elevated peaks around 2.5k and 5k, knowing that I am extremely sensitive to 5k. However, that is what my ears, or my brain, tell me, so who am I to argue?

However, I have to say once more that, although I cannot say that the EA1000 are not a great set of IEMs, they certainly are, I just don't find myself in love with any of the three tunings.

I don’t think that the EA1000 are a set of IEMs that will please those who want a bassier, more laid back, signature. Nor will they be a good option for those who are sensitive to boosts in the upper ranges but, for those who do like a little spice up top, they are certainly worth checking out.

Intro
It seems that much has already been said about Simgot's EA1000 though with the number of Chi-Fi releases and hype sets that are being released at a rapid pace, one has to wonder - is it still competitive now? I might be late reviewing my set and as much as possible, I wouldn't want to sound like a broken record. But to tell you outright, it still is one of the better timing to get yours when the opportunity arises as it is still very much competitive (and impressive) in the $200 space. With the advent of Simgot's new batch lineup dawning, it might be the best time to dip someone's toes onto the Simgot flavor of tuning the Harman curve to a tee. Read on to to find my short insights, you may refer to previous reviews for the unboxing and package details though it is a bit of delight and a touch of premiumness in opening these up compared to a majority of other Chi-Fi releases.



Build and Inclusions
The EA1000 comes in a purple somewhat-laser foil box with no evident waifu here. Inside, you have the IEMs themselves in their hefty glory. Feels solid and premium, as it never fails to put smiles onto faces of those I shared experiencing and having them audition in meets. It's been consistent that they can't believe it's worth $200 because ot does feel that it should be priced higher. It comes with a silver-colored flip-top magnetic case and has 3 sets of eartips. The cable is noteworthy to feel very solid and untangly. The looks match the IEMs themselves and is terminated in 3.5mm SE. Lastly, you get 2 sets of tuning nozzles aside from the one already installed - 1) silver with red black ring and 2) gold with white ring though most probably I feel the default silver with red ring sounds the best for me and will be the basis for my impressions.



Sound
The IEMs do feel classy and sturdy with their all-metal shells and glass faceplate with white-pattern and it does sound like it too. The single DD with the passive radiator combine to create a very premium sound that truly resonates in your ears unlike any other in its price bracket. The bass is very defined and of high quality, aspects that are present in higher tier sets. Kickdrums and lows do feel as if they are ever present with proper decay and still quick in response, not sounding pillowy or anemic. Some might prefer to have a bit more quantity though and it is not a bassy set in any sense. The mids and vocals also shine and are more than adequate, none too lean but a bit forward in the upper registers and might come off as shouty to some. What is another impressive aspect to note is the treble and air region. Its brilliance is actually giving it a very energetic and dynamic manner of handling notes while being airy and spacious. It does give you a sense of space and pinpoint imaging, considering its just a single dd set. Though admittedly, for those who are treble sensitive, they might find it spicy or at times sibilant hence why the set is either you really love it or hate it and find it harsh. Undeniably so, this is one very technical set but also toe-tappingly good to listen to without being to analytical. In comparison, the DUNU Falcon Ultra has that somewhat smooth warm response to it so it does create a contrast in the $200 single dd space. I have yet to try the Origin though this set does leave the older Tanchjim Oxygen in the dust. And the Katos and Arias are undeniably inferior to the EA1000 in terms of both product execution, durability and overall sound quality as some might even find the Katos boring when played side by side along with the EA1000. For a different Simgot sound and as complement, one might find the EM6L as a good addition while for those who find this set too peaky may want to go down and might find the right overall mix with the EA500 LM for a touch smoother execution of the similar EA1000 flavor.



Conclusion
The Simgot EA1000 still stands as one of the more impressive sets in its pricepoint and has continuously impressed those who I have it auditioned to, both newcomers and audio vets alike. I, for one, will keep my set for a long time and will be a mainstay as side-by-side against other single dd implementations. It just does a lot of things other sets are unable to standout with. Harsh it may be for some, if one can tolerate its treble response then this set is a keeper. Not to mention its durable and hefty build but fits like a glove for most. Still, one I would recommend for those curious to give it a chance and listen. I just recently converted a couple of newcomers to purchase theirs upon first listen compared to the other budget releases out there. A commendable set from Simgot and they would only go forward from here to create a true flagship in their stable.

Simgot EA1000 "Fermat" Review ​

​

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
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
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
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.

Aesthetic ​

–Build Quality: 9.8 Built very well, HeyGears builds are great.

–Look: 9.9 Clean, fresh, simple, elegant.

–Fit/Comfort: 9.5 Fit and comfort is great for me.

–Accessories: 8.1 Very well accessorized.

–Overall: 9.3

Sound Rating ​

–Timbre: 9.5 Top class timbre.

–Bass: 9.6 Impactful, detailed, defined.

–Midrange: 9.1 Clean, resolute, separated, dynamic.

–Treble: 9.8 Extended, detailed, precise.

–Technicalities: 9.7 All technicalities are great.

–Musicality: 8.3 Nice mix of musical and technical.

–Overall: 9.3

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!

Simgot is a premier manufacturer of earphones with a focus on delivering superior audio fidelity, cutting-edge design, and unparalleled user experience. Simgot earphones are known and well regarded by many audiophiles. You can read my previous Simgot reviews here.

The Simgot EA1000 is an upgraded version of the Simgot EA2000, so while the latter is the company's flagship model, the former utilizes more recent, cutting-edge technology. Simgot has code-named the EA1000 as “Fermat's Last Theorem”, you can read the philosophy behind this decision here.



Technical stuff

The EA1000 combines a 10mm dynamic driver (DD) that is paired with a passive radiator (PR) in a rather unique configuration.

Derived from the flagship EA2000 and further optimized, the second-generation DMDC™ dynamic driver revolutionizes earphone design. Unlike traditional single-magnetic circuitry, DMDC™ dynamic driver offers both inner and outer magnetic circuits, delivering unparalleled magnetic flux.

The heart of the EA1000 lies in its extraordinary SDPGD™ Technology. Developed over three years by Simgot, this diaphragm features remarkable characteristics, including high rigidity, exceptional hardness, lightweight construction, and the perfect blend of elasticity required for deep bass. Unlike conventional titanium or beryllium diaphragms, the Purple-Gold Diaphragm undergoes a meticulous process involving multiple layers of transparent, custom-targeted vacuum high-temperature sputtering on a specialized base film.

You can read more about the Simgot EA1000 here.

Detachable nozzles

Like many other earphones, Simgot EA1000 features a threaded, interchangeable nozzle design for further sound optimization. It comes with three nozzles, one brass and two stainless steel, each one with its unique tuning philosophy.

The first detachable nozzle with the silver-steel tube & red silicone ring adheres to the popular H-2019 target curve. Simgot informs us that this is a tuning more suitable for interpreting different music types and sound source quality, and can also meet the needs of professional musicians for recording and mixing.

The second detachable nozzle with the golden-copper tube & white silicone ring adheres to the Simgot Golden 2023 target curve. A new target curve introduced by Simgot which maintains the balance of the three frequency ranges and further enhances resolution, human voice and the high-frequency air. A target curve for better interpretation of live music, classical and other genres.

The third detachable nozzle with the silver-steel tube & black silicone ring adheres to the Simgot classic target curve on the basis of ensuring accurate positioning and clear image, in the dimension of three-frequency balance while it further emphasizes the female voice.



Non Audio stuff

Using high-density alloy metal and CNC engraving technology, a strong and pressure-resistant all-metal body is created through multiple processes. The unique uneven surface inside the chamber also helps to suppress standing waves. The highly transparent crystal panel and the mirror plating process complement each other to display fine luster and elegance. The Simgot EA1000 is a very beautiful looking earphone that harmoniously combines luxury with a minimalistic and discreet design. Build quality and finish are exceptional, the EA1000 is one of the best looking and well made earphones I have ever tested. The polished metal surfaces and the glass faceplates can attract fingerprints but this is the cost you have to pay for its shiny looks.

The metallic ear-shells are not that lightweight as they weigh 11g each but they are compact and have an ergonomic shape that follows the natural contours of the ear. The actual wearing experience is that of a very comfortable earphone, the EA1000 fits well and you can wear it for hours without feeling any kind of annoyance or discomfort.

Cable

The EA1000 comes with 0.78mm 2-pin detachable cable that is made from high-purity silver-plated OFC wire with Litz twisting process. This is a well made cable that is lightweight enough, it doesn't get tangled and has minimal microphonic noise. My only objection is that it doesn't feature interchangeable plugs and you don't have the option to order it with a 4.4mm plug. A cable with a single ended 3.5mm only plug at this price point is rather outdated when almost every source on the planet features balanced outputs.



Accessories

The package includes a luxurious and well made carrying case, three pairs of sound tubes mounted in a metal plate, six pairs of silicone ear-tips and spare filter rings. All the included ear-tips are of the same type so you don't have the option to do some fine tuning. The inclusion of different types of ear-tips would be more beneficial to the overall package.



Audio stuff

The Simgot EA1000 is rated at 16Ω and 127dB/V so it is really easy to drive but at the same time a little vulnerable to source noise so it is recommended to use something of high quality. For this review I have used the iBasso DX260 and Cayin RU-7 with an aftermarket balanced cable made by Lavricables. As per usual practice the Simgot EA1000 was left playing music for about 100 hours before listening evaluation.

The EA1000 is an earphone with a balanced tuning and great versatility thanks to the three different types of detachable nozzles that you can use to fine tune the sound. The overall sound signature is mildly V-shaped and you can use the three nozzles to micro-manage the intensity of the low-end and the treble while the mid-range remains mostly unaffected.

The red nozzle has the best bass extension but also the least emphasized upper mid-range and treble thus making it the most dark and warmer sounding of the bunch. This is a tuning quite close to the Harman target but without exaggerated sub-bass or too emphasized mid-bass thus making the EA1000 suitable for listening to a wide range of music, a true all-rounder with plenty of high quality and non-dominant bass. The two other tubes will slightly attenuate the lower bass to make it even more neutral and a better choice for listening to classical music or other critical applications where tonal accuracy is desirable.

No matter the sound tube used, the bass of the EA1000 is of the highest quality, fast, tight and controlled with excellent definition and very satisfying layering, qualities that surpass all expectations. The textures are not that full bodied and visceral but not dry or lean either while they pose great physicality and plenty of clarity. The bass might not sound that weighty but it is very impactful with wide dynamic contrasts and natural reverb without any audible echo.

The mid-range is crystal clear and transparent, with solid presence and without too much upper mid-range emphasis, at least when using the red nozzle. The timbre is natural and organic, the EA1000 excels in reproducing voices and instruments that sound tonally accurate and realistic with plenty of harmonic contrast and rich overtones. Fans of female voices can use the other two nozzles that add some upper mid-range spice and emphasis but without overdoing it as to induce harshness and listener fatigue. The EA1000 is musical and engaging, vivid and lifelike, it sounds addictive and emotional with all kinds of music.

The treble is energetic and airy, luminous and transparent with great overall extension. The red nozzle is the smoother while the black is the most sparkling and brilliant one. The gold attenuates the high treble while emphasizing the upper mid-range giving more prominence in this particular area. No matter the tube used, the EA1000 is a well tuned earphone that manages to sound lively, detailed and crystal clear without becoming too bright or fatiguing.

The EA1000 is very resolving and refined with excellent tonal and textural coherency throughout the whole frequency range. The benefit of using a well implemented single dynamic driver. From the deep lows all the way up to the highs, the notes are reproduced with the same gravity and intensity.

The soundstage is wide and spacious with plenty of air around the performers and good positioning accuracy from the left side to the right. Depth layering is not class leading but not bad either while the EA1000 is grand and immersive enough to go well with large scale symphonic and choral works.

Compared to the FiiO FD5

The FiiO FD5 is a popular choice for a single dynamic driver earphone with a tuning style that adheres to the Harman target curve. The FD5 has a more aggressive V-shaped tuning with better sub-bass extension but also with more prominent mid-bass that makes it less neutral and accurate than the EA1000. It is also brighter but more safely tuned in the upper mid-range while you can use the spare, smaller nozzle, to slightly attenuate the treble and make it sound warmer and more bass prominent. Both earphones resolve very well for the category but the EA1000 is the more refined and transparent sounding of the two. The FD5 is more visceral and weighty in the low-end but not that well defined and controlled as the EA1000. Both sound open and spacious but the EA1000 images a little better and allocates more air around the performers. I would say that the FiiO FD5 is the more fun and bass prominent earphone while the EA1000 is a better all-rounder and more suitable for critical listening.



Conclusion

The Simgot EA1000 is the best earphone the brand has made up to date as they have masterfully cooked all the right ingredients to make a tasteful dish. The EA1000 is an earphone that combines great sonic performance with proficient technicalities, nice appearance, comfortable fit and exceptional workmanship. It is also very adaptable thanks to the three tuning nozzles that can be used to effectively fine tune the sound to the listeners specific preferences. It is really very difficult not to like the Simgot EA1000 which rightfully so stands out as an easy recommendation and a great bargain.

The price of the Simgot EA1000 is $219.99 and is available from Linsoul .

Simgot's EA1000 "Fermat" is a dynamic driver IEM that features 2-drivers, one of which is a normal powered dynamic driver, and a second one being a passive radiator. While passive radiators are commonly found in desktop powered speakers to get a bass impact response when typical smaller speakers can't achieve it, there's only been a small handful of IEMs that have only recently started adding similar ideas into an in-ear monitor.

The EA1000 sells for $219 USD and is available at many retailers including Linsoul and Amazon and AliExpress. The product was sent for review directly from the manufacturer.

Simgot gets a lot of kudos for their presentation of accessories here. The included light gray polyurethane-leather case is really cute and small, but fully functional. It has a magnetic closing flip lid, with enough space for the IEMs and a small pocket for the detachable filters and other small accessories.




The included cable is a matching silver/white 2-wire cable that terminates in chromed-aluminum 3.5mm jack and 2-pin connectors to the shells. There is subtle color in the way of the gold-chrome chin strap hardware, and a very subtle rose-gold rim along the faceplate. It's otherwise a very minimalistic and white-out look that I think looks really great.

Simgot is really big into the filter game, and they've included 3 pairs of filters that change the tuning ever so slightly. The default setting is a chrome/red nozzle, with an additional set of chrome/black, and gold nozzles included. The red setting is my favorite of the bunch, while the black is just a tick more upper-mids/lower treble. The gold adds even more upper-mids and makes it more forward sounding and was my least favorite.

Sound Impressions​

The EA1000 has a slightly U-shaped sound that almost enters in V-shape territory with a bass range that has a slight focus in the mid-bass, and a slightly recessed mid-range followed by a slightly uneven treble range that changes depending on the filter of choice.




The key feature of the EA1000 that I really liked was how dynamic it sounded with good impact and punch, while also providing a very clean presentation. It's perhaps a tad thin despite having an elevated mid-bass, and that's likely due to the faster-sounding driver and focused energy in the treble range.

That aside, it does lend its way to having good imaging and sound separation, and I was surprised by a lot of the technical aspects of this IEM. It could use a tad more meat in the bones on some tracks, but it's still more than enjoyable.




On some female vocal tracks, such as Maeta's Cool Cat, there are some occasional highs that can be a little abrasive and its not quite as smooth as I'd like playing it out of the Hiby R3 II audio player. With the Fiio M15S, this is tamed down a bit though, and I really enjoyed the pairing of these two. Once I enabled my preferred MESB setting, the Hiby R3 II's treble sharpness did subside enough though.

All of that taken into account, I found the EA1000 Fermat to be a nicely tuned IEM that can perhaps be a tad bright on some notably treble-heavy tracks, but it has surprisingly good technical chops that I don't think I was really expecting given what I would have considered a gimmicky Passive Radiator driver and a single DD.

SIMGOT - EA1000 Fermat: Great Value for the Money!



Summary:

Launched in Oct'2023, Simgot launched IEM EA1000 Fermat as an upgrade to their previous EA2000. The EA1000 comes with new hybrid 1DD+1PR architecture and interchangeable nozzle system. The EA1000 looks great and also provides a great musical performance. Coming at a price range $219.99, the EA1000 comes with steel shells which though heavy, are quite ergonomic and comfortable. The sound experience is just great for the price range which we will see from the details below.




Introduction:


Let's quickly dive into the details without making the introduction very lengthy. The EA1000 features 1 Dual Magnetic Dual Cavity Dynamic Driver +1Passive radiator hybrid architecture. It comes with interchangeable nozzle system. The overall presentation is indeed praiseworthy.

The Simgot EA1000 is priced at $219.99.






Design & Build:

The shells are very premium looking and ergonomic and made of steel based material. The overall looks can compared to any higher range IEM. The shells are quite comfortable despite the hefty weight of steel. I have found them very comfortable throughout long listening sessions.

It is described as the following on the website:





Disclaimer: Simgot had sent me the review unit for my impressions & views. The opinions below are based on my own personal experiences with the unit and my own. I have tried to be as comprehensive as I could be - to give a complete picture to the audience.


Specifications:


The EA1000 comes at $219.99 price tag and the specifications are as below:

The Interchangeable Nozzles:


The SIMGOT EA1000 Fermat comes with 3 different nozzles: 2 metal and 1 Bronze.
The key differentiating factor other than the material seemed to be the amount of sponge inserted into the nozzle.




1. The Default metal nozzle (RED ring): This has half of nozzle filled with sponge-like material. The Staging seems balanced. The mids seems very slightly thinner. Bass response is overall good. good details good depth.

2. The Black RING metal nozzle : This has full-nozzle filled with sponge-like material. The Staging seems a bit more distant. The mids seems thinner than the default. Treble becomes slightly more prominent.

3. The BRONZE nozzle : This has NO sponge-like material. The Staging seems a bit more intimate. The midrange seems significantly more textured and meaty. The Bass response is deeper and more detailed. Treble seems slightly less prominent but just enough.

I have used all of the 3 nozzles and found that the Bronze one suits my preferences better than the others.




Ear Tips:

I have tried many different ear-tips with the EA1000, starting from Spinfit W1, CP500, CP100+, JVC Spiral Dots+, Final Audio Black & Transparent ones.
But the best fit and isolation for my ears had been AZLA SednaFit ones. I have hence used them for majority of the review.

NOW LET'S TALK ABOUT THE SOUND....



Items Used for this Review:

DAC/AMP & Dongles: @Questyle M15 Dongle DAC/AMP, @MOONDROP DAWN PRO

Portable Players / Sources : @Cayin N30LE, Astell & Kern SE300, @Questyle QP2R

Streaming Source: QOBUZ





Tracks Used:

The tracks I have used can be found from the below playlist that I have used and generally use for most reviews...











Pairing Performance with different sources:

Dongle DAC/AMPs:

EA1000 had the best pairing with @Questyle M15 & @MOONDROP DAWN PRO dongles. But, I have found that it pairs well with other dongles like @iFi audio Go Link, etc.




Portable Players:

Obviously the EA1000 had the best pairing with the Cayin N30LE, @Questyle QP2R & specially Astell & Kern SE300 since that comes with Class-A amplification! The BEST pairing however came with Cayin C9 + Astell&Kern SE300 with Class-A amplification enabled. That just took the performance of the EA1000 to the next level.




EA1000 Sound Impressions in Short:


The BASS:

The bass performance of EA1000 is amazing specially with the brass nozzle. The Bass overall feels very enjoyable with good speed and muscle. The details of the sub-bass region can also be felt and is very enjoyable. The attack & decay were both very enjoyable. Tracks like: "Hotel California (Live on MTV 1994) – Eagles" and "Fluid - Yosi Horikawa" are quite immersive.


The MIDS:

The midrange of the EA1000 with the brass nozzle is quite open and clear with ample amount of texture and details. The midrange is quite textured and full-bodied. Vocals are very immersive and both male and female vocals come with good texture and feel very real. Instruments felt very natural and real with high accuracy and the separation between them is also great. The transients were accurate & adequate and very very enjoyable. In tracks like: "Anchor - Trace Bundy", "A dog named Freedom – Kinky Friedman" and "Ruby Tuesday – Franco Battiato" it’s really easy to get lost into the music as it comes with ample detailed transients, texture, excellent vocals and details.


The TREBLE:

The Treble is quite smooth and non-peaky on the EA1000 with brass nozzle. It has the right amount of details and energy and is in no way harsh or peaky. Treble in tracks like: "Paradise Circus – Massive Attack", "Mambo for Roy – Roy Hargrove” and "Saints and Angels – Sharon Shannon" feel very immersive and enjoyable from the treble perspective.


The SOUNDSTAGE:

The Staging capabilities of the EA1000 is quite wide and balanced. The nozzles provide quite a bit of flexibility when it comes to staging. People can change based on their own preferences. Tracks like: “The Secret Drawer – Bela Fleck and the Flecktones” or “She Don’t know – Melody Gardot” or “Bohemian Rhapsody (live aid) – Queen” sound amazing & enjoyable with the brass nozzle.



Imaging & Timbre:


The Imaging & instrument separation performance on the EA1000 is also quite good. Tracks like: “Rotterdam (Or Anywhere) - The Beautiful South “or “Hello Again - Howard Carpendale & The Royal Philharmonic Orchestra” just shine through. The Timbre also feels very natural with the brass nozzle.





Comparisons:

I did not have any similar architecture IEM with me which I could compare the EA1000 with. I had the Moondrop Aria 2 with me which I have used for comparison in this case. The Aria 2 though much lower priced comes with single DD architecture.



Simgot EA1000 vs MOONDROP Aria 2:



Price: Prices of both IEMs are very different. The EA1000 comes at $219.99 while DMAGIC Solo comes at $89.99.

Build, Comfort & Features: The SIMGOT EA1000 comes with interchangeable nozzle system, while the Aria 2 comes with interchangeable connectors. I have found the nozzles more useful in a lot of scenarios throughout the duration of my use.

Bass: I felt despite being excellent for it's price range, the Aria 2 fell behind the Simgot EA1000 specially with the bronze nozzle. The punches were deeper, the sub-bass was more prominent.



Mids: This is amongst the key strength of the Aria 2 and the midrange in Aira 2 is great for the price range. The Simgot EA1000 could only match Aria 2 level midrange with the bronze nozzle. The other nozzles seemed to have made the midrange sound slightly thinner.


Treble: The treble experience on Aria 2 is good, but on the Simgot it is much better owing to the flexibility of the nozzles..

Soundstage, Imaging and Separation: This is where the SIMGOT had a clear advantage and owing to the nozzle flexibility. With the Brass nozzle, the staging was slightly better than the Aria 2.



Conclusion:

The EA1000 experience is great and also feels effortless. the overall musical experience is very enjoyable. The interchangeable nozzle system brings variety and flexibility. I think it is a good value for the price.

Source: Fiio M15
+Build: Really nice, has a nice and luxurious feeling to it. Good ergonomics. The faceplate looks really beautiful. However I feel like the housing is similar to the Kato, which is very prone to scratches. Should be handle with care
+Accessories: The cable is wrapped in a thick pvc coating which feels really good and supple in hand. I don't know if this would turn into yellow in the future like Kato’s stock cable, but in general, I give these stock cables a really high score.
Bass 9/10: Enough slam and punch to me. No midbass bleed. Subbass just needs a touch more rumble to feel more completed. Overall, i quite like the bass on the ea1000 if i were to compared it against Kato’, recommend using final E tips
+Mid 11/10: This is the part that surprised me the most. Both male and female vocals are extremely good and natural. Male vocal sounds lush and emotional, not thin like some MD brand. High mid feels forward and Especially there’s no sense of sibilance in the midrange.
+Treb: Sparkly, airy, not harsh sounding, sounds natural. One of the best treble qualities for under 500$
+ Technical: Separation between instruments is good. Nice and clear layering. Pretty wide soundstage, although not THAT impressive compared to many other iem that i've try, for example Neusonik Direm Pro II The soundstage will be wider and will have a more pleasant feeling. Acceptable in the price range
+ Can be endgame in the sub 250$ price bracket
+ Absolutely kills many iem in the same price range from the MD brand
+ Good price to performance ratio
+ Photogenic. Can be used to flex

Introduction

Simgot, the brand that stands for "Simple and Elegant" has re-released a flagship model that uses a second-generation dual-cavity magnetic dynamic driver. This is the Simgot EA1000 Fermat. Upgraded directly from the EA2000, the EA1000 utilises cutting-edge technologies such as SDPGD™ technology, the powerful DMDC™ dynamic driver and the 1DD+1PR hybrid architecture that delivers a fuller and more accurate high-quality sound, greatly enhancing the listening experience. The EA1000 incorporates Sputter Deposition Purple-Gold Diaphragm technology (SDPGD™) technology, which is a specialised diaphragm manufacturing process that results in a diaphragm with high rigidity, lightweight properties and a beautiful purple gold colour. It also employs second-generation DMDC™ dual magnetic and dual chamber technology, optimised for increased magnetic flux and improved control, providing a wider frequency range, exceptional dynamic range and accurate high-frequency performance. The EA1000 uses a 10mm dynamic driver (DD) paired with a passive radiator (PR) configuration. This innovative design improves 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 natural ambience. Finally, the EA1000s also feature three pairs of interchangeable threaded mouthpieces, which use materials such as brass and stainless steel. With these, users can switch between 3 different tuning styles, extending the adaptability of the headphones and catering to different sound preferences. It is clear that Simgot has made a considerable technological effort in creating this new flagship model. Let's see how that effort translates in this review.

Packaging

The Simgot EA1000 Fermat comes in a dark purple square box, whose dimensions are 150x150x50mm. On the front side you can read directly "Fermat's Last Theorem 1637-1995 Demonstrate". This refers to the fact that the conjecture called "Fermat's Last Theorem", made in 1637 by Pierre de Fermat, was not proved until 1995 by Andrew Wiles. It was then that the conjecture became a theorem, after 358 years of effort by mathematicians. The theorem can be stated as follows:

If n is an integer greater than or equal to 3, then there are no positive integers x, y, z, such that the equality:



is satisfied.

This theorem is one of the most famous theorems in the history of mathematics and the one that has taken the longest to prove.
Moving away from the mathematics and back to the product, in the top left corner you can read the brand name and its slogan underneath. In the top right corner is the DMDC™ II (Dual Magnet Dual Cavity) technology logo. At the bottom left are the logos of the SDPGD™ (Sputter Deposition Purple-Gold Diaphragm) and DD+PR (Dynamic Driver + Passive Radiator) technologies. All in gold lettering on that purple background. On the back you can see the three frequency response curves of each nozzle. Each nozzle corresponds to a reference curve. At the bottom are the specifications in several languages, including English. After opening the box there is a black cardboard with the logo on the front side. On the top of the cardboard are the names and dates of the mathematicians who have contributed to solving the proof of Fermat's last theorem. This cardboard is like an envelope, containing a description of the history of the theorem, and on the inside is a card with Fermat's face and the statement of the theorem itself. Behind this cover are three sections containing the capsules, the storage box and the accessories. The capsules are embedded in a foam base protected by black cardboard, located at the top. At the bottom left is the box containing the case. At the bottom right is the box containing the accessories. The complete contents are as follows:

• The two Simgot EA1000 capsules.
• Black and gold card with the statement of Fermat's theorem.
• White card with the formula of Fermat's theorem.
• A sheet containing 6 pairs of translucent white silicone tips, sizes SxMxL.
• A bag containing 8 white, 8 black and 8 red rubber washers.
• A metal plate containing four filters (two brass with white washers and two metal with black washers).
• A rectangular box-shaped case with magnetic closure.
• The high purity silver plated OFC cable in Litz structure, with 2Pin 0.78mm interface and 3.5mm SE plug.

The box is slightly different from the other boxes. It is silver-grey and has the brand logo inscribed on the lid, while the slogan is on the back. It comes in a protective plastic bag. The inside of the case has a sewn rubber band with three compartments, like a pencil case, on the lid. The inside of the case is slightly velvety and has a black pouch with stitched netting at the base. Inside the case is the cable. The cable plug has a plastic protector. The filter plate is inside a black foam block.
The presentation is quite good and the accessories are of good quality, especially the cable and the case. The silicone tips are somewhat generic and there seems to be no difference between the two pairs. The inclusion of the spare washers is appreciated. On the other hand, it is surprising that the model has such a Fermat's theorem image - what is the connection to the model beyond the name?
Finally, one misses the fact that there is no choice of a balanced plug in a model of this price.



Construction and Design

Simgot repeats the successful design of the EA500, adding a white outer plate with a triple arrow pattern on the bottom. In the centre of the outer plate is the brand logo in mirror silver. This plate is made of a highly transparent glass panel. Otherwise, the shape, size and design of the inner side is almost identical to that of the EA500. The Simgot EA1000 features a polished and shiny construction with a two-tier design on the inner side. The capsules are made of metal, except for the outer face, and are mirror-plated. Each consists of two visibly separated faces. The outer face has an equilateral triangle design, with very rounded corners. The border reads 'Fermat' engraved in cursive letters. The rigid, translucent plastic part, which contains the gold-plated 2Pin 0.78mm connection, is slightly recessed. The inner side has two levels. On the lowest level there is a recessed oval, which contains a circular opening, at the bottom of which there is a gold-plated metal grille. It looks like the grille that protects the PR driver. This opening is partially covered by a circular plate held in place by two ribs, in the centre of which is the letter of the channel. Away from this opening, near the base of the mouthpiece and the rim, there is a hole. The second level of the inner face is more rounded and contains the mouthpiece. Close to it is another hole, the bottom of which is protected by a white cloth grid. The nozzles are inclined and have a thread at their tip for attaching the metal filters. The filter with the red O-ring has nothing inside, while the black filter has a foam of the same colour. These filters are made of metal. The third filter is made of gold-plated brass, has a white gasket and has nothing inside. The nozzles have a length of 4.5mm, a smaller diameter of 5.1mm and a larger diameter of 6.1mm at the rim.
The cable consists of two thick strands wound together. It is a high purity silver plated OFC conductor in a Litz structure. You can see that the wires are silver plated with a thicker, flatter wire winding them inside each strand. The protector is transparent PVC. The cable has a velcro strip with the brand slogan. The sleeve of the 3.5mm SE gold-plated plug is a perfect metallic cylinder with a mirror finish. You can read the brand name inscribed lengthwise on it. To protect the cable at its exit it has a tailor-made plastic sleeve. The splitter is again a shiny, silver-plated perfect cylinder, shorter in length. The pin is a gold-plated ring whose inner diameter fits the two strands quite well, doing its job correctly and effectively. The sleeves of the 2Pin 0.78mm connectors are both silver cylinders that maintain the mirror finish, but have a circular groove near the cable exit. The two pins are mounted on a piece of hard plastic, the first base of which is circular and the second rectangular. The letter of the channel is engraved on each cylinder. The cable is somewhat stiff, thick and with a luxurious mirror-metal finish addicted to fingerprints.
As mentioned, the shape of the EA500 model is repeated, albeit with the distinctive addition of the outer face and a thicker cable and improved metal sleeves. Construction is excellent, with a fingerprint-trapping mirror finish, but very robust. You can feel the weight and quality of the materials used, something that also comes through with the cable. Too bad there is no choice of balanced plug.



Adjustment and Ergonomics

Although the capsules look a little large, the two-level design of the inner side of the capsules makes them ergonomic and easy to position inside the pinna. The angle of the mouthpieces is also very good. It is true that, on the whole, they are a little short and the insertion does not go beyond the surface. With some tips, a slightly deeper insertion could be achieved.
You also feel that the weight in the hand is evident, but in the ears it is not noticeable, thanks to the remarkable level of fit and integration. The capsules barely rotate and the fit is high, once you find occlusive and well-fitting tips, as is usually the case with my large foam-filled home-made tips. Thanks to them, the level of isolation is remarkable.



Sound

Profile

The EA1000 has three pairs of nozzles to slightly modify the frequency response. The nozzle with the silver tube and the red washer is based on the H-2019 reference curve, but without reaching such a high sub-bass. Actually, I would have liked it to reach this sub-bass end to compensate for the clear and bright character with some more power at the low end. With the second mouthpiece, made of gold-plated copper and white washer, you get the reference curve of the brand itself, called SIMGOT-Golden 2023. The third nozzle, with a silver tube, black washer and black foam inside, produces the SIMGOT-Classic reference curve. You can see that in all of them there is a drop in the sub-bass that does not reach the level specified by each curve.
Actually, according to my measurements, the differences between the three nozzles are not very big. They follow a rounded w-profile, with excited midrange and neutral bass. The Gold filter is the most relaxed in treble and bass, but is the most excited in the 2khz area. It works for female vocals and is more neutral. The black filter that matches the brand's Classic reference is the most excited in the high end and a bit more penetrating for my taste. Finally, the red filter has more bass and is closer to the H-2019. Not that I am partial to that curve, but I do have more affinity for a tuning with a high sub-bass. I will write this review using this filter.
In short, all tunings lean towards a search for clarity, light and sharpness in the sound, so the bass is somewhat more relegated in the mix, but without its execution and response not being good. And that is something that is achieved with the passive driver, which helps to make the bass more impressive, but without overdoing it in energy, volume or presence.



Bass

The passive radiator is very similar to a dynamic driver, but lacks a coil and magnet. It consists of a cone and a diaphragm and moves with the air displaced by the active dynamic driver. Its purpose is to add low-frequency reinforcement by resonating with the bass frequencies emitted by the active dynamic driver itself. In this case, that does not imply a very high, powerful or heavy bass frequency response. This is not the case at all. Even with the red filter, whose FR is close to the reference H-2019, these IEMS cannot be said to be bass-heavy. It is true that the lower area can be felt and there is power. But I think that the passive radiator has been used to compensate the low end against a more extended and balanced high end. In my opinion, the bass presence is slightly above neutral, subtly centred in the middle of the low range, with a slightly droopy sub-bass, which prevents it from sounding deeper, but with a tuning that gives it a natural behaviour. On the other hand, the passive radiator works very effectively and does not produce any delaying or sluggish action in the bass performance. On the contrary, the base hits are succinct, fast, tight and compact.
In the very low frequency pure tone tests this dry, but natural, uncoloured behaviour can be appreciated, although it can also be seen that the lower frequencies do not have too much power or presence, while their performance is a sensory and audible mix at 50%. This behaviour adds that blend of naturalness, darkness and depth, with the former characteristic benefiting the most. Its translation to real music implies a tight, perceptible bass, not too voluminous, with hardly any aftertaste and a quick recovery. It feels agile, dynamic and capable. In addition, I feel that the passive radiator brings extra texture to an area that, given its characteristics, could be smoother and blander. It's not that it's a rough bass, it's rather clean, but with that extra descriptive touch across its surface, which adds a very attractive, yet natural and more complex feel to it. The whole is very well blended and the behaviour in complicated, dirty passages, with unfiltered bass and excessive power, the EA1000s come out completely well, representing these situations with astonishing ease, but without losing an iota in all its execution. It proves to be a very descriptive, very skilful area, capable of following difficult, intricate lines, defining layers and layering them with fluency and exemplarity. For my personal taste, it lacks a little more energy, volume and depth, a more sensory point. But, it proves to be a great low end, really natural and capable all-rounder.



Mids

The midrange is very clean, clear, transparent, highly resolving, but with a hint of abruptness. I feel that the EA1000s have this cooler, very defined and purely descriptive profile, which takes it away from a softer and more melodious musicality. I like this kind of very well defined profiles, but, it is also true that I miss some more body in the first half of the midrange. I think it is possible to be cold and resolute, but keeping more physicality in that initial phase. This slight lack makes the male vocals lack a bit of edge and punch, sounding very clean, but lean and somewhat thin. I can't deny that they have a good width, but the thinness of the notes makes me miss some weight and energy in the lower voices. On the other hand, their articulation is very good and the dynamics are high, achieving very fast transients and generating a very resolute and descriptive response.
As the frequencies rise, the energy of the notes can be higher, reaching a splashy, present and slightly penetrating midrange. Warm or neutral sources are welcome, to compensate for the cooler, more resolute and sharper development of the second half of the midrange. But despite that thinness, its energy does not overflow, without becoming totally piercing. It is a vibrant, sparkling, fine and swift performance, with that cool, sharp definition, but not hurtful or piercing. It can be a bit abrupt, if this word is used to define a very mobile and resolute sound. Perhaps, so much descriptive capacity can generate this sensation of abruptness or informative fatigue. But, to my ears, it is a sound that is explicit and analytical, detached, clean and effective. But, up to a point. All this ability to tease out nuance and detail generates a very obvious and broad exposure of it, even obscuring micro details located in later layers. That foreground macro detail works against them when it comes to revealing micro details that exist at the same time, but in different layers. It is clear that the EA1000 is capable of expressing them, but when they exist together, they tend to lag behind these main details.
As for the female voices, they are the real protagonists of the range, as well as the stringed instruments or guitars. Their timbre moves between neutrality and a brighter point. It has many harmonics and the notes are enriched by a great amount of nuances, as well as the air, separation, distance and definition to be easily observed. All this makes for a truly rich, highly representative and informative central range, very suitable for music monitoring. On the other hand, the lack of a wider physical base unbalances the midrange towards the high end, slightly polarising the sound towards a brighter, colder and more analytical sound.



Treble

The treble picks up on the many virtues of the dynamic driver: speed, precision, thinness and finesse of notes, energy, definition and resolution, to generate a very expressive, eloquent, sparkling and crisp high end. There is no doubt that the EA1000s have a generous and extended treble, full of power and energy. But they stop at just the right point, or perhaps a little beyond it. If you are looking for soft treble, the EA1000s are not the most appropriate. But if, on the other hand, you are looking for a totally explicit, crisp and defined treble, these Simgot have it. It is also true that the Gold mouthpiece is able to subtly mitigate this behaviour, being the softest of the three, but that slight loss of bass also exposes the treble in a different way.
As the high frequencies advance, they relax their energy level, but their decrease is perceived as controlled, generating an extended high end, with naturally bright and realistic treble, though on the bright side, of course, fully expressive and evident. The extension clearly reaches the air zone and its quantity and incidence are appreciable.



Soundstage, Separation

The scene feels volatile and very airy. The separation and distance between notes reveals a spacious and wide scene, which enjoys very good height, even three-dimensional capacity. Without encircling the head, it has a very good sense of envelopment, thanks to its extension. It lacks some depth in favour of width, laterality and stereo feeling. The dynamism, speed and thinness of the notes help to generate this gaseous and escapist sensation. But it is also able to profile instruments and vocals very well, helping to create a precise and very well positioned image. The sound is very resolute, highly descriptive, clean and transparent. The background is clearly discernible and the elements evident and finite. The midrange and macro detail in the foreground shines through. But, as often happens in these cases, this explicit feeling is capable of obscuring the micro detail located in later layers.



Comparisons

BQEYZ Wind

The BQEYZ Wind had a higher price tag when they first came onto the market. Today, they can even be found at a lower price than the Simgot EA1000. Their technical qualities make them a clear competitor to the Simgot EA1000. Swap the passive radiator for a midrange and low-frequency bone driver and you get the BQEYZ Wind, an IEMS that is also very high-performance, with a similar profile and performance. Starting with the accessories, the cable of both is really very similar. The sleeves are practically the same: perfect cylinders with a mirror finish. The cable is made of two coiled strands. Only the slightly darker colour of the wind conductor seems to be different. Meanwhile, the cable cross-section is almost identical and both the splitter and the pin are also identical, except for the gold-coloured pin on the EA1000. The advantage is that BQEYZ does give a choice between the three terminations. For the rest of the accessories, the Wind offers a larger zipped case, a larger number and variety of tips and the classic cleaning brush.
When it comes to ergonomics, the EA1000s fit very well in my ears and fit very snugly. However, the somewhat short mouthpieces prevent a very occlusive seal in the canal. The mouthpieces of the Wind are somewhat longer and the capsules seem to float more in my ears than fit. However, thanks to the design of their mouthpieces I get a more perfect seal using the same large foam-filled tips.
In terms of sensitivity, the Wind requires considerable power to match volume compared to the EA1000, which are much easier to move.
In terms of profile, the Wind have a very similar frequency response to the EA1000 with the Gold filter. But I preferred to compare using the red filter for the Simgot. The differences between the two with this red filter are visibly concentrated at 2kHz and above. While the EA1000s have a more sustained treble in terms of energy, the Wind is subject to slight control drops in the treble in an attempt to smooth out the upper range.
Regarding the low end, here we are talking about a struggle between two technologies used: the passive radiator used by Simgot in the EA1000 and the bone driver for low and midrange frequencies used by BQEYZ. In my humble opinion, the Wind behaves in a darker, deeper and more natural way than the EA1000. The Simgot's have a bit more colour, seem to be drier, slightly more bass-midrange focused. They may be a little faster, so if you are looking for a precise, technical and tight bass response, the EA1000s will be more appropriate. On the other hand, the Wind's bass is executed with a darker timbre, offering a more sensory response, with a little more texture and volume, which creates a sense of a deeper bass with more range and persistence in the room, making it more enjoyable, but a little more intrusive.
In the midrange, starting in the upper-midrange, you can feel how the EA1000 has a bit more vigour, energy and sparkle in its performance. That gives it a point of clarity, light and superior transparency. The Winds are somewhat more neutral comparatively speaking, also softer, subtly warmer and more mellow. While the EA1000s are even more resolute and evident, with finer and more defined notes, the Wind's feel a little more controlled. The combination of bass darkness and those more shaded midranges and highs contribute to the Wind's less analytical presentation. Their transitions don't seem as quick as the EA1000's, while they lose some transparency and sparkle in their notes, falling a little behind in definition and resolution. The EA1000s are more demanding in this department, sounding more explicit and descriptive, also more analytical, precise and crisp. Conversely, they are also a little more abrupt and persistent, while the Wind are a little lighter to handle in this respect. Perhaps there can be a debate as to which of the two has a better timbre, or a more natural timbre. Perhaps the Wind is more neutral, while the EA1000 has a brighter timbre. But better or worse in this respect may be a matter of taste. Perhaps, in my humble opinion, the Wind provides a more natural or closer to reality timbre. Above all, this is reinforced by the presentation of the bass and the first half of the midrange of the Wind, where the notes are somewhat more diffuse, thicker, darker, but also softer and with a little more body and physicality. Finally and because of these characteristics, the Wind are less sibilant than the EA1000.
The EA1000's apotheosis of clarity in the high end is evident on the Wind. The Simgot's are able to maintain an even, extended energy level throughout the entire range, giving even more of an airy feel to those with this element as their model name. On the other hand, the Winds are softer, don't soar as much, don't sound as crisp and sparkling, and even possess a touch of comparative nuance. The high notes are thinner, thinner, more precise and more evident in the EA1000s. But that level of energy can also become more fatiguing because of its level of exposure.
In terms of separation, the EA1000's greater sense of transparency, light, sharpness, resolution and definition give it the edge in this respect. The greater depth and sense of openness, however, is more noticeable in the Wind, offering a slightly larger stage on all three axes.
The level of macro detail is not as overexposed in the Wind, something that allows a homogeneity in its exposure and allows greater visibility of the smallest details, being a little more delicate with them. Meanwhile, the EA1000 is critical and very exposed in this aspect, capable of being very resolute, but offers a more favourable treatment of macro detail, exposing it above the rest. It is not that there is a loss of detail compared to the Wind, it is just that their exposure is more uneven.
All in all, both IEMS are great rivals and no one would go wrong choosing one or the other. Differences in bass, timbre, smoothness of exposure, level of resolution and definition are the differences. The Simgot's are built like a tank, while the Wind's are a little more delicate with those external grilles, but also slightly less heavy. Finally, the possibility of having three slightly different tunings with the EA1000 may be an advantage in terms of being more sonically versatile.



Conclusion

Simgot manages to capture in the EA1000 what it has been exhibiting in the rest of the lower-priced models: a reference sound, clean, very clear, bright and pure. It adds three mouthpieces to reinterpret this degree of refinement, based on three reference curves, two of its own and the H-2019. And it achieves this great sound with the use of efficient and imaginative technology. It seems that behind this sound there are many hours of work and the result is an analytical, very informative, rich, very special IEMS for the monitoring of music and, of course, for the enjoyment of it.
Built on the very solid base of the EA500, but with the addition of a distinctive, superior touch, expressed on the outside and with a much improved cable, the EA1000 is a true flagship model with a great price/performance ratio.

Presentation


Hello, friends of AvaliaSom, I'm Marcelo Dosec, and the one I bring you is the Simgot EA1000 Fermat , a unit that was kindly sent to me by Simgot. Thank you very much! As usual, I will only give my personal opinions about the phone, without any obligation to say good or bad.

This IEM costs 220 USD (or around 425 USD with 92% Brazilian taxes in current legislation). As you can see, it's hard to be an audiophile here in Brazil.

It's no news to anyone that I like Simgot. On my list of favorite IEMs throughout my life, I have the EW200 and the EM6L, and I even had them on my 2023 favorites list. And, if you'll allow me a spoiler, I have an EA500LM here, and it's going to be on my list too.

But after all, what about the EA1000? Does it deserve a place in my heart and also on my list? Ok, I will answer this question at the end of this text.

The EA1000 Fermat is just below the EA2000, which is currently the brand's flagship, and I hope to buy it one day. From its more expensive brother, the EA1000 brought the passive radiator (PR), a feature still little explored in IEMs, and the models that use it can be counted on one hand. The PR has a structure similar to that of a dynamic driver (DD), but without voice coils or magnets, working passively according to the air flow displaced by the DD during its operation. In both the EA1000 and EA2000, the function of the PR is to give more depth and body to the bass.

Its unboxing follows Simgot's quality standard, and in the case of the EA1000 it brings a reference to Fermat's last theorem, a mathematical problem that took 358 years to be solved, and has been included in the Guinness Book since 1995 as “the most intricate mathematical problem of history.”


The external purple box is very beautiful, well built and features a reference to the aforementioned theorem on the front, while on one side there is a visual representation of the driver arrangement. On the back of the box, we find graphics for each of the nozzle combinations that the EA1000 offers.


The internal box moves laterally, as in the EA500 and EM6L. After opening it, we highlight the card alluding to Fermat, and just below we have the headphones in their cradle, a small box for the bag and another box that stores the accessories.


The synthetic leather bag is beautiful, and has a magnetic closure. In a light gray color, it has the Simgot logo on the top and the words “Salute do Art and Science”, the phrase that is present on other products from the brand. Very spacious, the bag has a mesh inside its fabric, as well as three elastic spaces to store accessories.


And speaking of accessories, the accessories box comes with a case of tips, which are the usual Simgot silicone tips, of good quality. There are also silicone rings in red, black and white/transparent, which, similar to what occurs on the EA500, are the rings that identify the different nozzles.


Above the nozzles, there is a metal stand that holds two of the interchangeable nozzles, with a pair of them already attached to the IEMs. As stated on the box, the silver nozzle with a red ring adheres to the 2019 Harman curve. The silver nozzle with a black ring adheres to the classic Simgot curve, while the gold nozzle with a white/transparent ring adheres to the Simgot curve. Golden from 2023. Two interesting facts: the golden nozzle is made of copper, while the others are made of steel. And the golden nozzle does not have any acoustic foam inside, just a damper next to the grille.


The IEM comes with a beautiful oxygen-free copper (OFC) cable, silver-plated and litz, with connectors, chin slider and splitter made of metal. Interestingly, the gold chin slider brings a beautiful touch of sophistication. The connections are 0.78 mm 2-pin for the earphone and 3.5 mm for the source.


The IEM itself exudes sophistication, with the entire body made of mirrored metal, with a faceplate that features a kind of resin window, the interior of which features a white background with textures and the Simgot logo in gold. The shape of the internal part is reminiscent of the EA500, with the difference that it has the PR output in the upper section, whose internal grille is gold, and the external grille has the L and R indications according to the sides of the phone. Its two-pin connector is slightly sunken into the metal body, protecting the connector.

The EA1000's sound is generated by a 10 mm dynamic driver (DD) with a diaphragm coated in purple gold, combined with the performance of a 6 mm passive radiator (PR). The DD in question is derived (but not the same) from the EA2000 driver, and is the second generation of DMDC technology belonging to Simgot, which uses a double magnetic circuit and double cavity system.

Comfort


The comfort of an IEM is a personal matter, and for me at least the fit of the EA1000 is excellent. Its body is very ergonomic, with no sharp corners. The nozzle is narrow, 0.6 cm in diameter (the same measurement as a Simgot EM6L , for example), and allows a shallow fit with L tips or a medium fit with S or M tips depending on the ear canal. As it is a ventilated headset, there is no pressure on the ear canal, but the seal is just good, and in noisy environments it isolates you to an average extent.

Musical Sound

I tried the IEM on my sources, which are: Dell Laptop, Apple Dongle, Truthear Shio, Simgot DEW4X , FiiO KA5, Cayin RU6 , Sony NW-A306 , Topping G5 and FiiO K7.

Note that I always listen to the earphones at low volume levels, around 55 to 65 dB according to the measurement made by the Apple AirPods Pro 2 in the “Health” App on the iPhone, so my impressions may differ from those who listen at higher volumes taller.

By the way, I invite you to check out my headphone test playlist on Spotify . This is a dynamic playlist, and the songs can change at any time, but they will always follow the purpose of presenting all the points I mention in my musical evaluation of the headphones.

Regarding sources, the Simgot EA1000 plays easily on any source, and the differences between one source and another are due to the particularities of each one.

• Tone

The Simgot EA1000 has three different types of tuning, and its tone varies according to the nozzle used. To my ears, it sounds like a V using the red nozzle, and sounds neutral with the other nozzles . I will use the red nozzle as a reference for this sound analysis.

NOTE: The following notes serve as a comparison parameter only in the price range in which the IEM falls.

• Bass: Level 4/5, Extension 5/5, Speed 5/5, Texture 5/5, Depth 5/5

In the first song I heard with the EA1000, it was possible to notice the refinement of this guy. The bass sounds full, with impeccable texture and excellent extension to the subs. Obviously they don't sound like the cavernous subs of the BQEYZ Wind, but they are very correct and quite intense subs.

As a result, the beats of “Ambitions Az a Ridah” sound very intense and correct, and the bass feel of “Paranoid” is very appetizing, with a lot of note weight and great presentation. Cellos and double basses are also well presented, and although the EA1000 is not a basshead, it delivers very high quality and refined bass.

In terms of speed, the insane kick drums of “Intra Venus” are presented without any difficulty or mishaps.

• Midrange: Level 3.5/5, Presence 5/5, Clarity 5/5, Voices 5/5, Transparency 5/5

In terms of midrange, the Simgot EA1000 appears impeccable to my ears. These mids sound very prominent to me despite the V-shaped sound of the red nozzle, and I was impressed by both the clarity and the presence of these mids. Furthermore, voices sound very natural to me on this IEM and its transparency is excellent.

I must highlight how competent the tuning of this driver by Simgot was, as its mids sound as pleasant to me as those of the Kinera Freya 2.0, and I would have difficulty deciding which one is better. Listening to “Vilarejo” by Marisa Monte, it is impossible not to delight in the sweetness of her voice and instruments. In the case of more intense voices like Louane, the EA1000 is well controlled with the red nozzle, while male voices bring all the expected weight.

I didn't notice any sibilance in the track “Hello” by Evanescence, and I make a point of highlighting how pleasant Santana's guitar sounds on “Europe”.

• Treble: Level 4/5, Brightness 5/5, Airiness 4.5/5, Extension 5/5, Timbre 5/5

I know people who are prejudiced against more expensive IEM that don't use balanced armatures or EST drivers for treble. And I love saying how wrong this prejudice (or any of them, not just related to earphones) is. When a DD is implemented well, it can cover the entire spectrum with flying colors, and this manifests itself in the EA1000.

There is an excellent level of brightness with the red nozzle, very good airiness and a very natural, very pleasant tone. I didn't identify peaks or valleys in the treble region that could bring any artificiality or strangeness, and the extension of these trebles is enough for anyone who doesn't have superhuman ears.

That being said, it is extremely pleasurable to hear the cymbals of a “September in Montreal” with the EA1000, and even more pleasurable to see how Lindsey Stirling's violin carries a beautiful timbre and extends to the heavens.

• Technicalities: Sound Stage 5/5, Image 5/5, Layering 5/5, Separation 5/5, Details 4/5, Resolution 5/5

One of the points that helps define the selling price of a phone is how good its technicalities are. And technicalities are not witchcraft, they are the result of refining both the driver, the tuning, and the acoustic construction of the phone body. In the case of the EA1000, it is notable how much Simgot invested in acoustic refinement here, especially if we compare it to the EM6L or the EA500.

The earphone brings a very wide and holographic soundstage for an IEM, with a very interesting layering. The image painted in “Las Perlas de Tu Boca” is worthy of applause, and I direct the same praise to the separation of instruments and the resolution. It's fascinating how much you can notice each particularity of the music with this IEM in your ears.

One point where I think it is fantastic but not impeccable is the level of detail. Ok, it does deliver a great level of detail, but there are some microdetails missing here and there, nothing discrediting to my ears.

Sound in Games

In battle royale games, such as PUBG, the EA1000 is impeccable in delivering the position of opponents across the spectrum, with an excellent sense of distance, something that makes this guy worthy of a 5/5 with any nozzle. Rating 5/5.

In FPS games like CS2 ( without changing the sound settings ), the EA1000 also deserves high scores, especially with the white nozzle. No movement of opponents across the map is possible with this IEM, and it is definitely one of the best I have ever used for FPS games in my life. Rating 5/5.

In casual games, like Gensin Impact, the open world feeling is very evident with red nozzle, and the immersion is excellent. There is a very natural sound and it offers a high level experience. Rating 5/5.

And finally, in simulation games like Forza Horizon 5 , with the red nozzle there is a lot of intensity and depth of engine sounds, even if they are not bass that shakes the eardrums. Furthermore, there is an excellent sound from everything around, and the EA1000 ends up getting another top score. Rating 5/5.

Sound in Films, Series and Productivity

Because it has multiple filters, the EA1000 is very democratic in terms of use for films and series, with the red nozzle being more suitable for action titles, the black nozzle being the best option for more general titles and the black nozzle being ideal for documentaries or titles with lots of dialogue.

And for watching podcasts, the white filter is excellent, bringing voices to the front. The same goes for meetings, and given the comfort of the EA1000, for me it was possible to use it during a 12-hour work and study day without any problems.

Conclusion

Remember the question I asked at the beginning of the text? Well, the answer is a resounding YES. And I'll go further: with the Simgot EA1000 here, I wonder if it's necessary to have any other IEM wired in addition to it. In fact, this Simgot takes the term all-rounder to the maximum level. It definitely suited every use I tried to make of it, and it just wasn't able to replace my Apple AirPods Pro 2 for the obvious reason of having wires.

In short, it is a comfortable IEM, with extremely high-quality bass, very well-defined midrange and high-end treble, while also falling in love with the technicalities. And if the tuning isn't to your liking, just change the filter. Without any doubt I have never heard anything so versatile and enjoyable under 300 USD, and this place on my recommendation list is now his.

I still want to buy an EA2000 just to complete the collection, but thinking logically, the EA1000 replaces the entire Simgot line for me. And it also replaces all the headphones I've ever heard, even though it doesn't have the refinement of an Audiodream or the polish of a 64Audio. Just thinking rationally, this Simgot is everything I need.

Here's my suggestion for Simgot: how about a TWS with the sound of this EA1000?

Big hug!

Preamble​

The proliferation of Chinese Hi-Fi (Chi-Fi) in the audio scene in the last decade has led to a tremendous growth of audiophiles in the hobby. The barriers to entry have been lowered and appreciation for good quality audio is now in the mainstream. However, it is not all rainbows and candy unfortunately, as the prolific nature of Chinese manufacturers has led to unprecedented levels of choice for consumers. Herein lies the rub, there is now the paradox of people being crippled by the freedom of choice.

Today’s review concerns a Chi-Fi manufacturer attempting to enter the rather crowded price bracket of ~$200 USD. Simgot, a product of the Guangdong region that has produced many an audio company in the last decade, seeks to captialise on this rather dynamic market with their EA1000. But is the EA1000 another flash in the pan to be superseded by some new upstart in about 2 weeks? Or is there some staying power here?

The Factual Stuff​

The EA1000 contains a dynamic driver and a passive radiator. The latter is somewhat novel with examples in recent memory being products from LetShuoer and essentially is a cavity for sound tuning purposes.

The earpieces are seemingly steel polished to a high chrome finish and are adorned with crystal faceplates leading to a modern and clean aesthetic.

The EA1000 comes with some accessories including nozzles to tune sound, eartips, a carry case and an SPC cable terminating in 3.5mm

This review unit was also accompanied by Simgot’s cable, the LC7, consisting of mixed strands of silver and copper and terminated in 4.4mm, the LC7 is a $70 upgrade cable.

The Opinion Stuff​

Sound​

The following impressions were taken using the stock cable, silver stock nozzles, Spinfit W1s and paired with a number of sources primarily with the Shanling M6 Ultra.

Bass​

The low-end performance of the EA1000 is impactful and powerful in its production with a slight emphasis on the sub-bass region. Extension and physicality on the EA1000 are rather impressive with songs such as “THE PLAN” from the TENET soundtrack providing me with a strong and detailed reproduction of the opening bass line that extends quite deeply. This is a visceral listen with strong low-end oomph.

Mid-bass is dynamic and punchy, providing me with an impactful experience with speedier songs such as “Before Dawn” by Slander, which has a rather high BPM. Apart from quantity, the EA1000’s bass quality is heightened by a sense of speed as it handled both songs with gusto, providing fast decays and seemingly being able to keep up with faster-paced EDM.

Outside of these elements, the EA1000 also did quite well with detail and texture in the bass region, with lower-end notes being reproduced quite clearly and comprehensibly. There is no real boominess or woolliness to the bass region (perhaps owing to the speed) as it feels as though note edges are clearly defined and reproduced with distinct clarity.

Overall, the EA1000’s low-end presents a fast and dynamic reproduction of bass notes that presents a fun and enjoyable sound signature that heightens the impact and engagement factor of whatever you are listening to.

Mids​

The aforementioned push in the mid-bass lends itself to the imbuing of warmth and note weight to the lower-mids. Male vocalists such as The Weeknd in “Out of Time” presents with some low-end body. Unlike other ‘warm’ IEMs in the market which have a tendency of muddying up the lower mids and the mid-bass, the EA1000 manages to stay coherent and clearly separated.

“Comedy” by Gen Hoshino presents the laidback male vocals with a sense of depth and that was very enticing to listen to, however, this did feel a little bit more recessed in the mix than what I would’ve liked with the bassline and some instrumentalization sitting front and centre. In the grand scheme of IEMs however, I believe the EA1000 leans a little thinner in this region but is similar to Chi-Fi in the price bracket.

Moving to female vocals, “Winter Without You” by XG presents a wide variety of female vocalists in different ranges and the EA1000 manages to reproduce them fairly well with the slightest hint of shoutiness and edginess to the ‘sss’ sounds throughout. There is a slight fatiguing element here but also a rather dramatic and engaging experience.

For more instrumentalization I put on “Malenia, Blade of Miquella” from the Elden Ring soundtrack for some dramatic string production and the EA1000 handled it with gusto, presenting the rather harrowing sentiments that boss-level video game soundtrack should have!

Overall, the EA1000 presents some slight issues with its mid-range production with male vocals presenting in a more recessed manner and female vocalists presenting with a slight edginess and sibilance. These may be interpreted as being more soulful for the former and more dramatic for the latter and I think the EA1000 rides this line quite well.

Treble​

Moving to the upper end, the EA1000’s treble region is surprisingly reigned in at the highest regions of the FR curve. Whilst the upper mids have a tendency to be somewhat shouty, the reproduction of percussion in songs such as “Reckoner” by Radiohead don’t feel too harsh on the ear but rather sparkly in nature.

Electronic synths can be rather heavy on the ears in certain songs and I threw some of these at the EA1000 to see how it performed with “You & Me (Flume Remix)” being my go-to for a grating white noise in the ‘chorus’ to which the EA1000 generated a slight level of discomfort but nothing like more aggressively tuned IEMs in the market.

More nuanced productions that don’t lean too heavily on the upper regions like “The Demon Dance” by Julian Winding which has a brush on a hi-hat throughout the majority of song presented well with the little production flourish being clear and present in the mix with a slight edginess and speed to its production.

Overall, the upper-mids to lower-treble can be somewhat grating to the ear over time but as a whole, the treble is tuned rather well in consideration of a balanced approach towards excitement and ear-piercing fatigue.

Technicalities



As previously mentioned the above, the EA1000 stood out to me as having an excellent sense of speed and urgency to its production presenting notes in a clear and concise manner. This may not be everyone’s cup of tea but I feel it seemed to heighten a sense of detail retrieval and resolution as edges of notes were clearly defined.

Combine this with the rather excellent layering of notes presented a cohesive and coherent production that defied preconceptions held to the price tag.

Staging is also quite good presenting a nice sense of width and depth. It is not hugely wide nor deep by any stretch of the imagination with the former being sufficient when listening to wider orchestral pieces and the latter being mostly due to its ability to effectively layer notes with speed but is a good performer nonetheless.

Imaging and positioning are rather good cues for the sheer technical performance of an IEM and the EA1000 performed well with my preferred test of “Fine” by Taeyeon having a number of vocals layered over one another to which the EA1000 rendered them clearly and coherently whereas poorer performers seem to send out a single blob of vocals from one central location.

Call it confirmation bias but the passive radiator seems to do a great job of enhancing the performance of the single dynamic driver as my experience with single DD IEMs (especially in this price bracket) lacking technical abilities such as staging and perceived dynamic range.

Additional Round – LC7 Cable



Preaching the virtues of a $70 cable upgrade in a $200 IEM review sounds like asking for some ridicule but the review unit came with Simgot’s own LC7, a combo of SPC and copper terminated in 4.4mm.

If you’re dubious or perhaps a vehement cable denier, I’d recommend you skip this section as I believe the LC7 offers some sonic changes to the EA1000.

Compared to the stock cable, the LC7 seems to flatten out the tuning a little more as bass feels less present and the brightness is tempered somewhat as male vocals present more forward and female vocals sound less sharp to the ear.

The mids as a whole seem to get an uplift in presentation and that is not to say that the bass and treble is reduced to zero.

Otherwise, technically, the stage feels more deep and slightly wider to the ear as notes and layers of sound (that is, instrumentalization and vocals) feel more dissectible to my ear.

The LC7 presents the EA1000 with a balanced and enjoyable tonality and a technical improvement that I thoroughly enjoyed but whether or not it’s worth the price tag, especially being a significant percentage of the cost of the IEM itself, is another question.

Additional Round - Nozzles​

The inclusion of tuning nozzles has become somewhat common in Chi-Fi and allows for some fine-tuning of sound which provides the end-user with the ability to really dial in their new toy to their liking. However, I found that the EA1000's nozzles altered sound fairly minimally despite being noticeable on a quick change and repeating the song.
Ultimately, I prefered the stock nozzles for their balanced tonality and based the majority of my review on these.
The included alternative silver nozzle (with red marking) seem warmer to the ear but at the cost of some perceived resolving power and detail.
Finally, the gold nozzles feel more airy to the ear but also heightened the shoutiness of female vocalists even further, which exacerbated the grips that I had with the stock configured EA100.

Comparisons​

vs Dunu Zen Pro​

Hardly a fair fight at approximately 5x the price but considering the similarity in driver implementation, how much does 5x the money get you?

The Zen Pro has a similar lift in the upper mids to the EA1000 where things get a little shouty but has far less sub-bass to temper such tuning. The Zen Pro’s wheelhouse seems to be a punchy mid-bass and satisfying lower-mid region. In terms of tuning, it is a matter of personal preference but I would say the Zen Pro feels more tonally balanced compared to the EA1000’s more bombastic low-end. In terms of technical performance, I feel that the Zen Pro presents one of the most dynamic presentations available at nearly any price point with swings in volume presenting in a thoroughly enjoyable manner and helps add to the sense of ‘scale’ to the sound. The Zen Pro eeks out slightly more perceived resolution and layering to the sound in an A-B but not enough to warrant the 5x price tag.

Ultimately, I feel that the EA1000 presents a more exciting tuning and ultimately loses out in terms of dynamics, which does not sit at the highest of my priority list in terms of determining the IEM for me. I think the EA1000 in this regard punches above its weight and I would likely be disappointed if I had bought the Zen Pro unless I was truly seeking out dynamics as the main focal point of my listening experience.

vs BLON BL-03​

The consummate ideal budget IEM in my eyes, the BL03 presents a bombastic and fun sound signature at a low-cost but how would it deal with a more technical and balanced approach?

The BL03 whilst enjoyable and respectable for the price point, feels less defined and more slow than the EA1000 which excels in such aspects. The result is a slightly lethargic sound with a more bloaty and woolly bass and a diminishment of mids.

The BL03 whilst enjoyable for short spurts of dumb fun, feels far less refined for a longer-term listen to my ears as I started to get tired of the coloured tuning and wanted a more technical performer for more acoustic focused music.

The EA1000 feels more tonally balanced, more technically proficient and overall a better IEM in every aspect except for the subjective elements of tuning.

This is no fault of the BL03 given the price point but the EA1000 represents a noticeable step up that I feel warrants the price difference.

vs LetShuoer S12 Pro​

The future vs the past, still a single driver but this time in the same price bracket and using a planar driver instead of a dynamic one, how does the EA1000 deal with something in the same wheelhouse?

The S12 Pro is a technically excellent IEM that punches beyond its price bracket, resolving music with a tremendous sense of speed and edginess that exudes detail. The perceived dynamic range is also impressive with deep-extending sub-bass and airy highs that present music with an edginess and excitement to it.

The S12 Pro doesn’t have the greatest sense of physicality or impact to the sub and mid-bass (respectively) as compared to the EA1000 it feels more incisive and detailed as opposed to having sheer volume and impact.

The mids of the S12 Pro are more recessed in the mix compared to the EA1000 and have a tendency to come off as a little thin and floaty. The timbre of the S12 Pro is also slightly ‘metallic’ in its tonality in that I feel things sound a little unnatural to the ear.

In terms of the upper-mids to treble region, the S12 Pro also elicits a similar sense of harshness and edginess that can be fatiguing overtime but when combined with the aforementioned timbre feels much more difficult to listen to over long periods of time compared to the EA1000.

Ultimately, I feel that the S12 Pro outperforms the EA1000 from a technical standpoint with a more hard-nosed approach to resolution and detail but the EA1000 feels like a more enjoyable listen.

Quality of Life & Value​

The EA1000’s steel earpieces do a great job of imbuing a heftiness to the IEM that adds to the perception of build quality. They do less of a good job at adding to ergonomics as the shells, whilst not the heaviest I’ve experience presented some discomfort over long listening sessions and were quite quick to fall out if the seal was not perfect.

This is supplemented by the fact that the earpieces themselves were on the smaller side, something that I honestly struggle with getting a good, sealed fit with. This is likely a lesser issue with other people’s ears but something anecdotal I wished to point out.

The included cable with the EA1000 is only terminated in 3.5mm and usually this is not an issue given the limited price but considering cheaper IEMs these days are coming with modular cables with interchangeable terminations, I was somewhat disappointed at this.

The included accessories were rather limited but the carry case was a welcome addition despite being a mixed bag of a cheap looking finished combined with a premium-feeling magnetic clasp system.

Overall, the value proposition of the EA1000 at its price bracket, considering the accessories, the build and of course the aforementioned sound signature presented me with a wonderful combination of value. I feel that the EA1000 was a more agreeable, more enjoyable listening experience than the S12 Pro as well as provided me with a more ‘premium’ feeling unboxing and handling experience.

To this effect, I believe that the EA1000 represents excellent value.

Conclusion​

The EA1000 at first glance looks like any other Chi-Fi offering at the price range but looking closer reviews some nuanced design choices and additions that seem to separate itself from the market. With a relatively simple design language combined with the use of more ‘premium’ materials as well as novel tech in the form of the passive radiator, I feel that the EA1000 presents something of a uncommon approach to the Chi-Fi market that is highly enjoyable to listen to and can remain a part of a collection for a longer period of time than the flash-in-the-pan IEMs that pop-up every couple of weeks.

I can highly recommend the EA1000.

Summary:
To summarize the review EA1000 Fermat from Simgot is a single dynamic driver IEM with a passive radiator, priced at $220. Considering the price packaging is nice and it comes with high quality accessories. Build is solid and the design is fantastic. With a bright mild V-shaped sound signature, the EA1000 provides quality bass, clear midrange, and refined treble. Despite minor drawbacks such as sub-bass quantity and a bit thin upper mids, the overall sound quality is quite enjoyable. Technical performance of this set is quite good as well.



Disclaimer: this unit was purchased with my own money and this review is my honest and unbiased opinion, thanks.

Intro
This is EA1000 Fermat from Simgot, this is a single dynamic driver iem with a passive radiator. This comes in at $220.
Talking about Simgot, they are a well reputed chifi brand. They gained quite a bit of popularity from their EA500. I have previously checked out their EW200, which is the best balanced sounding single DD iem under 50$ in my opinion. I am planning to check out their EA500lm soon. Anyways Getting back to the EA1000, these have been getting quite a bit of hype recently, and I must say these deserve the hype.



Packaging/ Box Contents
This comes with a beautiful packaging for the price, I like the purple theme through out the box. The included accessories are also of good quality. This comes with,
Papers
Eartips (2 sets)
Cable
Tuning nozzles
Extra replacement mesh/ filter
Iems itself


Important Specs
Driver 10mm dynamic
Sensitivity 127dB/Vrms
Impedance 16Ω
Frequency response 10Hz-50kHz
Cable high purity silver-plated OFC wire in Litz structure

Build and Design
Let’s start with EA1000’s build, very solid
The shells are made of solid metal, aluminum I am guessing. The shells have nice weight to them, feels quite substantial in the hands. The shells are average sized. The face plate design is immaculate, it looks way more gorgeous in real life than any of its picture. The Simgot logo in on top of a patterned surface and it seems to be covered by glass giving it a 3d-ish look. Fingerprints or scratches can be an issue due to the polished finish, but its fine in my case. The 2 pin connector is recessed type. The nozzle is standard sized and also lipped thus it holds eartips quite securely. The shells are vented, so there is no pressure build up.



Fit and Comfort
Moving on to the fit and comfort section, it is good. The shells sit nice and flush in my regular sized ears. Breathability is good because of the vented design. Stability is ok, I did notice the iems slipping out sometimes but rarely, I am guessing because of its weight. I did not find any issues with long term listening, it was comfortable.

Cable
The EA1000 comes with a very nicely built stock cable considering the price. This is a 2 core silver plated copper (OFC) cable in litz structure. It uses a 0.78mm 2pin connector and terminates in 3.5mm. I wish the cable came with modular terminations. Connectors and the Y split are made of metal. There is no audible microphonics. Cable memory is basic, but a bit more softer cable would have been nice. The preformed earhooks are ok, they blend in with the color of the cable and did not cause any irritation. Cable weight and thickness is standard. In terms of looks this goes nicely with the white and silver theme.



Nozzles
The EA1000 comes with three sets of tuning nozzles. The difference between each nozzle is not very massive. Personally I used the silver with red silicone band one, I find this one most compatible with my taste.

Tested With
Source: cayin ru7, tempotec v3, hidiz ap80, apple type c dongle
Eartips: stock, Final E (best pairing), spinfit w1, spinfit cp145, Divinus velvet (2nd best pairing), azla crystals
Cable: stock, kinera leyding, kbear black blade
Nozzle: silver with red silicone marking
Music: Tested with versatile genre of music



Sound signature: bright mild V shape

Sound tonality
The EA1000s provides fantastic cohesion with a unique, clear tonal quality that highlights remarkable transparency. Despite their neutral sound signature, they stand out from many 'reference' tuned IEMs by avoiding any sense of dullness.

Bass
Let's delve into the bass performance of the EA1000, which is nearly flawless. Handled by a single dynamic driver along with a passive radiator, Simgot's choice of drivers deserves praise; you can truly sense the quality of the dynamic driver with every beat, delivering that classic dynamic punch. In terms of positioning, the sub-bass is subtly rolled off compared to the mid-bass. The sub-bass, thanks to the passive radiator, feels tactile, but a bit more quantity would be better. Mid-bass is more forward and it provides ample punch. Overall, the EA1000 has a fast and precise bass response, somewhat like planar bass. The body and layering are executed well, with instruments like the bass guitar and kick drums sounding accurate. Decay and reverberation are satisfactory, and bass note separation is solid. Personally, I did not find it to be bloated or muddy in any way. The only drawback I can think of is the sub-bass quantity.

Mids
Moving on to the midrange, the EA1000 prioritizes clarity and transparency. The transition from bass to lower mids is relatively linear, with minor and well-controlled bass bleed. Thus there's a hint of warmth in the lower mids, which contributes to the smoother male vocals. However, I've noticed that female vocals and the upper mids, in general, can sound a bit shouty and thin. While this doesn't get sibilant or harsh, it might be fatiguing for treble sensitive listeners. Nonetheless, I quite enjoyed the energy and intimacy present in the midrange. Note weight and separation are satisfactory. Instruments sound clean but is also slightly affected by the upper mid boost.



Treble
Transitioning to the treble section, Simgot has opted for a bright tuning for the EA1000, and I must say it's executed quite well. In short the EA1000's treble is refined, well-extended, and it flows nicely with the entire frequency range. Details are crisp without being too in your face. It is easy to spot intricate nuances. Occasionally, instruments sound metallic due to the boosted upper mids. While there is no significant harshness or sibilance issues, treble sensitive listeners may find it bothersome. The speed is normal to fast type. Personally, I find this tuning wuitw enjoyable with rock, metal, and electronic tracks. The airy presentation enhances the sense of space in the soundstage. This has good resolving capabilities.

Technical Sound:
Soundstage of the EA1000 is good, nothing extra ordinary. All three plains are above average, this has good width but the height is lacking. Stage depth is not bad.
Imaging is quite impressive. EA1000’s imaging is very accurate and its very easy to pin point instruments.
Sound separation and layering is surprisingly good
Resolution is solid considering its price and driver count.
Dynamics are good
Timbre is good



Conclusion
I have quite enjoyed my time with the EA1000 and I think this is worth the $220 price tag. Other reviewers are saying the new EA500lm is much better value, and I can’t say until I try that. But so far I can say for sure this is the best Simgot has to offer. If you like bright-ish mild v tuning definitely give this a try. Props to Simgot they did a awesome job with this one.

I will be focusing this review on sound quality to make it as short as possible. So you wont get bored reading it.

The Simgot EA1000 (220 USD) is a mid-priced single-dynamic driver IEM with a passive radiator to enhance the bass.

The shell is metal and chrome-finished, and the faceplate is made of glass. The weight is on the heavy side, and the size is medium. The looks and feel are very elegant, and my unboxing experience is very positive.





Eartips and Cable:
The stock tips look and feel very good, and the cable is above average in quality as far as stock cable is concerned.

Pairings:
For this review, I used ePro EP00 medium eartips and Tripowin Seraph cable. I would like to emphasize my use of the ePro EP00 tips, as this IEM sounds the best with this tip. I use the red ring nozzles as I cannot take the aggressive sound of the other two nozzles that's included. I included photos of the graph I measured so you can see the frequency response of each nozzle. (see photos). Note: The peak at 8 kHz is a measurement artifact.
For the source, I use a Moondrop Dawn Pro dac/amp connected to an Android phone. This IEM sounds its best with warm-sounding sources.

Tonality:
A moderate V-Shaped sound signature that is slightly leaning on the bright side, even with it's mildest tuning nozzle, the red ring nozzles.




Technicalities:
The sound stage has average width with decent depth. They are not the biggest I've heard, but they don't sound cramped in and claustrophobic; there is a good amount of space within the sound stage, so it feels like you are in a club or a discoteque kind of environment at most on some songs.
The imaging is quite good, especially when used with the ePro EP00 eartips; they are well focused and could project sounds coming from behind. I thought someone was playing a musical instrument behind me, outside the wall of my house, and I had to pause the music to check. The left-right imaging is also decent, but it doesn't project very deep, making the front-back separation just average, but still decent enough not to make this IEM sound claustrophobic.
The detail retrieval is impressive, but the micro-detail is not the best that I've heard.
The power handing is very good. The sensitivity is above average. The dynamics are bubbling with energy. This is not a boring IEM, for sure.

Bass:
It is MId-bass focused and tight, but not devoid of sub-bass; there is still audible sub-bass that can be enjoyed. The upper bass is tight and clean and doesn't encroach on the lower mid-range. The overall bass sound is textured and detailed, and not a trace of muddiness can be found.

Mid-range:
The male vocals are noticeably behind the female vocals in their presentation. The lower mids are more recessed than the upper mids. The upper mids can sound too forward with the wrong pairing of Dac/amps and eartips. The overall sound of the mid-range is clear, detailed, and highly resolving, yet it still sounds musical.

Treble:
Energetic and slightly elevated, but not sibilant and harsh. It has impressive detail retrieval, but the micro-details lag behind. This has the best detail retrieval in a single DD IEM I've heard so far, but my experience with single DD IEMs is limited, so you can take this with a grain of salt.



Comparison method: I A-B them while writing this to avoid errors as much as possible. The eartips used in all the sets in this comparison are the ePro EP00 medium eartips.

Versus Kinera Celest PhoenixCall (110 USD):
They have similar tonality and timbre, with PhoenixCall sounding more recessed in the mids. Both have similar detail retrieval, but the PhoenixCall has a little more micro-detail nuances. Both have similar-sounding bass, but the bass on the EA1000 is more detailed and textured and seems to go deeper too, but by just a small margin. The bass on the PhonixCall is a little warmer.

The EA1000 is more prone to being shouty in the upper mids when paired with the wrong source; the PhoenixCall is more tolerant regarding the source pairing.

The PhoenixCall is an energetic-sounding set, but the EA1000 is more so. Both can take high amounts of power and can go very loud, but the EA1000 leads in this regard, albeit only by a small margin.

Both have a musical and engaging sound.

The PhoenixCall has a bigger sound stage.
The EA1000 is more natural-sounding; not that the PhoenixCall isn't; it is, but there is something about the sound of single-dynamic driver IEMs that makes them sound more natural than IEMs with multiple driver configurations.

So which one should you choose? The EA1000 is more expensive but has a classier-looking shell and feels more expensive as a whole, including the packaging and the unboxing experience. On the other hand, the PhonixCall cost only half the EA1000 and also has very good packaging and shell design and offers similar sound quality.

My advice is that if you can only afford the PhoenixCall, get the PhoenixCall; you are not missing out much, but if you can afford the EA1000, buy it. There is something so good about its sound that is impossible to describe in words that makes it worth its price.




Versus Hidizs MP145 (160 USD):
The MP145 is a warmer and bassier-sounding set; it has more micro-details and nuances in sound. The treble is delivered with more finesse and delicacy. The sound presentation is on the relaxed side and could sound a little boring and lacking in dynamics. The mids are more recessed. The sound stage is bigger. The bass could sound a little boomy and lack control when paired with an amp that has a high output impedance.

The EA1000 is more energetic and engaging. It has more macro-details and resolution. The sound presentation is closer and more immediate. The transient response is faster. The EA1000 has better imaging. The bass is much tighter, cleaner, and more detailed. The sensitivity and power handling are higher. Overall, the Simgot has a clearer sound.

So which one should you get? Get both. The MP145 is an excellent example of a planar IEM, and the EA1000 as a single dynamic driver IEM. Personally, if I could only have one, I'd get the EA1000.




Versus Xenns Mangird Top (550 USD):
The Xenns Top is a hybrid set that consists of a 10mm dynamic driver and 8 balanced armature drivers. It sounds more neutral and less energetic. It has more macro and micro-details and is more resolving, but not by much.

The Xenns Top has a bigger sound stage and better imaging and layering.

Both have very good power handling and sensitivity.

The EA1000 sounds more engaging and fun to me, and the Xenns Top sounds more serious.

The Xenns Top feels lighter and less expensive; the EA1000 looks and feels much better, IMO.

Personally, if I could only have one and have to do it all over again with the knowledge that I have now, I'd get the EA1000; it is less expensive and more fun to listen to.




Versus Simgot EA500 (70 USD):

The EA1000 is more energetic on its mildest-sounding red tuning nozzle than the EA500 on its wildest black tuning nozzle, but even so, the EA500 sounds so thin and fatiguing that I can't listen to it for more than an hour, while I can listen to the EA1000 for many hours without fatigue.

The EA1000 is better in every way than the older and less expensive EA500; it has more extension in the bass and treble, a much bigger sound stage, better technicalities and tonality, is more resolving, and, as I said, is better in every way.

The EA1000 is an excellent upgrade to the EA500.

Pros:
+ good looks
+ excellent build quality
+ excellent packaging and accessories included.
+ excellent sound quality
+ Impressive resolution
+ very good tonality
+ fun-sounding

Cons:

- sound stage is not the biggest.
- Micro details are not the greatest.





The big question is: is the EA1000 worth its price premium over the vast majority of budget IEMs costing 100 USD and below in terms of sound quality improvement? My answer is unequivocally yes. And considering the whole package, even more so. Would I recommend the EA1000 to my personal friends? Yes, if they can afford it.

If you're looking for an upgrade in sound quality, design, and build quality from your $100 and below IEMs, you can afford it. I highly recommend the Simgot EA1000.

Simgot EA1000 - $219


Pictured above with the Simgot LC7 cable, sold separately and features modular jacks with 3.5mm and 4.4mm

Introduction & Caveats etc…

Any of you that know me will know I have quite a thing for single dynamic drivers, usually my preference in this hobby and I’ve explored a large number at this point. I’ve typically gone for mid to higher end sets and most recently reviewed the wonderful DITA Perpetua which is certainly at that higher end considering the $3K price tag.

Simgot have had a lot of praise in the community over the last number of months, they appear to have really caught the attention of audiophiles with a selection of products from their range that have garnered huge praise for the price to performance ratio - most notably it would seem the EA1000, the subject of this review.

When Simgot reached out to ask if I would like to try the EA1000 I was very happy to accept, and would like to thank Fia from Simgot for the opportunity - as always, all words are my own without any influence, payments, etc etc etc…

The EA1000 retails for $219 and available from many different sellers to include Amazon, Linsoul, Elise Audio to name a few.

A bit about me...

I worked in the consumer electronics industry for a large part of my career, and have been passionate about music and technology from as far back as I remember - even as a small child asking my Mum to put records on the turntable (Abba, Supertramp and Planxty if anyone is curious )

My music preferences are very varied - anything from classical to techno, indie rock to jazz and all in between. In my early teens I was a big fan of bands like The Cure and The Smiths (still am all these years later), and I was bitten by the dance music bug that arrived in the early 90s where I became hugely passionate about genres like techno, house, trance and IDM - I amassed a huge collection of records and CDs, DJing with the former at various parties and occasional pirate radio station slots - a hobby at the time that I never took further, but still own 1000s of records and my trusty Technics 1210 turntables are still going strong 30 years later, a testament to the Japanese engineering!

I am not a professional reviewer or anything remotely like it. I love music, and I love the methods by which we can listen to music - over the last few years, that has become an obsession with IEMs and related gear. I've bought and sold many, and held on to a select few - these have been anything from a $20 set like the Moondrop Chu, all the way up to kilobuck sets such as Aroma Jewel, the infamous 'Traillii' from Oriolus, UM Mentor, and a whole selection of my beloved single DDs. As part of this exploration, I like to share my thoughts on the various sets in my journey with the Head-Fi community, in the hope it might be useful to others. The massive caveat, is of course that 'your mileage may vary' - this is a highly subjective hobby.



EA1000 Specifications

• Drivers: 10mm dual-magnetic-circuit & dual-cavity structure dynamic
• Cable: High Purity Silver-Plated OFC Litz Structure
• Connector Type: Detachable 0.78mm 2Pin
• Jack: 3.5mm

Simgot it seems have some interesting technology at play here in the EA1000, with the use of their patented ‘SDPGD’ driver - that being a sputtered purple gold diaphragm & ‘DMDC' dual- magnetic dual-cavity dynamic. This driver is described by Simgot as “powerful effective magnetic flux makes the sound driver have more amazing performance, which not only greatly improves the dynamic range and transient capability of the earphones, but also provides a wider bandwidth range” - they expand on this to say “the “Fermat” EA1000 also enhances the control of high frequency, which gives the “Fermat” EA1000 a stunning dynamic shock and presence. As well as the high frequency characteristics of rich abundance and smoothness, rich air sense and ductility, the exploration of the upper limit of the dynamic is a step closer.” - in addition to this driver performance, there is a 6mm passive radiator which enhances the low-frequency, something I experienced previously with the much more expensive MA Eclipse ($1,199 or so...) which likewise had very distinct sub bass in particular, quite like that of a sub-woofer in a 2.1 setup. Anyway, leaving all the tech aside, the EA1000 does sound like more than a single driver.



Unboxing

I’m going to keep this pretty brief as there are numerous reviews out there already, but I still like to show a selection of shots as to what you get.











The accessories are somewhat basic but you get what you need:

• Storage case
• Selection of tips
• Interchangeable nozzle filters

Stock Cable

Unfortunately only a 3.5mm stock cable which I think is a shame even at the relatively low price, it has become almost the norm now to have 4.4mm and ideally options in the box to switch to your preference. It is however a nice lookling and well made cable.



Case

The case is a fairly typical style, which is practical for storage and has a nice extra feature of slots to store modular plugs should you purchase the likes of the LC7 from Simgot which has both 3.5mm and 4.4mm (and is the cable I've been using since the EA1000 arrived in early January).





I like also the net at the bottom, handy for storing spare tips or the tray with the various tuning adaptors.



Design & Fit



Long before these ever landed, I had always thought they looked eye-catching from pictures I had seen - they certainly didn’t disappoint when they arrived, looking and feeling every bit as good or even better. The shells are of a robust metal construction and while there is a bit of weight to them, this is not to the detriment of fit in my experience, i.e. they do not fall out of my ears when moving about which can be a risk with shells that have a bit more weight to them. I expect some micro scratches to appear on the inner sides of the shells due to the metal finish over time but nothing to report as yet - the outer shells have a nice patterned finish and as such I assume these should allow for a reasonable level of protection from scratches.

I find the shells sit comfortably in my ears, and provide a reasonable level of isolation - this will of course depend also on your choice of tips, in my case I’ve been using the Acoustune AEX07 in XL, now a go-to set of tips for a lot of my IEMs. I have used frequently out walking and around traffic and while they don’t block everything, it is pretty decent.

They are vented, so no issues with any pressure build.

Overall I find them very comfortable and could easily listen for extended sessions.

Listening Impressions

I’ve tried the EA1000 with a selection of DAPs to include the Hiby RS8, LPGT Ti, and the Sony ZX300 out and about. Just to note also, Simgot sent me the LC7 4.4mm cable and all of my listening has been with this rather than the supplied 3.5mm cable - the LC7 is sold separately for $79 (I do think the stock cable should have a modular option too).

The EA1000 to my ears is an IEM that is easy to enjoy or even love, I can’t imagine anyone actually disliking - a nicely balanced signature that is sufficiently resolving to produce good details from micro to macro, with a smooth and musical tonality - I haven’t experienced any nasty peaks in upper mids, nor any sibilance or harsh treble. Important to note, the vast majority of my listening has been so far with the the silver tube/red ring which I guess is the ‘standard’ or default option as the EA1000 ships with these attached - a harman 2019 tuning target which is quite universally pleasing. I hope to test the others soon and either include or update this review accordingly.



Lows

I can certainly hear and feel sub bass, the passive radiator doing a wonderful job of providing a tactile, visceral low-end presentation to these deeper levels. While the quantity isn’t massive, it is certainly more than adequate and of high-quality, plus nicely balanced in my opinion with the rest of the FR through mids to highs - nothing overpowering, nor I am left wanting with tracks that require good presence here. As noted earlier, it reminds me somewhat but to a lesser degree of how the passive radiator in the Melodic Artification ‘Eclipse’ presented sub bass with a feeling of being like a separate sub-woofer like in a 2.1 speaker setup. Mid bass has good solid impact for kick drums with a realistic sensation of vibration, likewise bass guitars have nice timbre and a good sense of reverberation.

Mids

Really excellent balance between clarity and warmth here, with ample space for vocals and instruments - the resolution providing plenty of detail, well defined and a great sense of instrument positioning in a wide field. The note weight is slightly on the thinner side, but has sufficient body for the lower mid registers regardless and portrays both male and female vocals very well. The all important ‘emotive’ connection is certainly present, and I find synths, strings, brass etc all highly engaging, realistic and captivating. Upper mids might creep into an area of sensitivity for some, I’ve found at times as instruments step up to this area that they just stay within my personal comfort zone - I think this is probably an area where tuning can be tricky to balance, as it seems this part of the FR needs a bit of a lift to provide an accurate account of vocals and instruments in this zone, and indeed what is then portrayed in a sufficiently captivating way. The

Highs

Treble is balanced seamlessly with the the mid and low frequency ranges, extending smoothly from the upper mid-range and offering well-defined clarity and detail, without being too bright, harsh or sibilant. The airy extension creates a sense of additional space in terms of soundstage size. It’s easy to zone in on intricate nuances of detail with hi-hats, the furthest extremities of violin strings, cymbal crashes etc - and indeed with more layered and detailed examples of say ambient music, where there is a lot of focus on field recordings and the more minute level of detail.

Technical

As noted, the EA1000 is a nicely resolving set and produces admirable levels of detail retrieval across a very respectable sized stage, especially for the asking price. Imaging is portrayed within a stereo field, with good centrally located position for vocals or instruments in this region, which sound accurately represented. There is a good sense of space between instruments, without any sense of congestion for busier or more complex music. While not clinical, it is very easy to perceive individual elements of the music in the mix, yet of course still coherent. There is a good sense of depth in the stage, with layering creating a sense of proximity to various elements of the music being closer or further away, cymbals and hi-hats for example often reach out beyond my head left and right.



Test Tracks

Vince Clarke - Red Planet

A highlight album of 2023 for me, and one I have listened to many times over the last few months. This track actually a great example of one that sounds like it’s title, it has an otherworldly feel to it where it builds to a dramatic climax, creating a sense of wandering the red planet’s vast landscape - it is very emotionally captivating and the EA1000 does an excellent job of providing that sense of the vastness of that distant world of Mars, synths extend out to great distance and the more climatic moments sound dramatic but not harsh or congested, also demonstrating the dynamic capability of the set with fast transition from quiet to busier and ultimately louder moments.



Omni Trio - Sleeper

And now for something completely different - jumping straight to one of my favourite test genres for any IEM, some quality D&B (Drum & Bass) from the legendary Omni Trio - a huge favourite for me when out walking, I love the pace and complexity of the music, along with typically sweeping and emotive synths, deep cavernous sub bass, and fast-paced percussion. This sounds wonderful - the intermittent bass line that emerges every so often really drawing attention to the passive radiator at work, where it has that sub-woofer sensation. As the track progresses, and the drumming becomes even more complex, the EA1000 has no difficulty keeping up with the pace and driving every bit of detail - likewise ensuring the big sweeping synths swirl out to the furthest reaches of the stage, creating a highly immersive listening experience.

Side note: I really wish Omni Trio would reissue all back catalogue albiums to Bandcamp, I have their albums on CD but could do with better digital remasters!



Portico Quartet - Beyond Dialogue

A really beautiful blend of jazz and electronics from the excellent Portico Quartet, from the excellent album ‘Art in the Age of Automation’. I’m again immediately captivated by the sense of space, and overall clarity, positioning and dynamic range from the loudest to quietest moments. Instruments sound accurately portrayed, and again highly emotive and engaging. I have to point out again as I keep perceiving this - I love how the EA1000 presents the likes of hi-hats in a smooth, coherent way that pushes them out in a visceral way to the furthest edge of the stage - creating a wide stereo sound field. Bass doesn’t dig as deep as the previous track, but still has a sense of a sub-woofer presentation, albeit more subdued by the nature of the track.



Violeta Vicci - Autovia

The self-titled track to the brilliant ‘Autoviva’ from 2019. This again does an excellent job of demonstrating how the EA1000 copes with a ‘large’ sounding piece of music, one that needs to have the space to allows the synths, strings, and other electronic elements to flourish - again handling the dynamic range, the multiple layers, and balance across the FR to accurately represent what is ultimately a complex, subdued, yet dramatic and beautiful piece of music.



Abfahrt Hinwil - Radiowellen

This tracks features on the classic 'Links Berge Rechts Seen' album which was originally released on the legendary Toytronic label in 2002, but lovingly reissued by the also arguably now legendary Lapsus Records from Spain, they've been doing a sublime job of unearthing IDM classics from the past few decades and presenting them to the world again on vinyl. While not overly complex, there are multiple layers and a lot of intricate detail - the percussion has more of a mid bass focus with an offbeat kick-drum which presents wonderfully in the centre of the mix - the many layers of synths present with a beautiful melodic captivating tonality. This is another track I've heard countless times over the years since I originally picked up this album on CD in the early 00s, EA1000 doing a mighty fine job playing it to me again.



Autechre - VLetrmx

I'm probably being a bit indulgent here as I've started to think of tracks I've known and loved for many years that fit in the IDM theme, Autechre of course for those of you who know them are unquestionable legends of the genre, and on the scene now since the early 90s. This track is actually more ambient in reality as it is completely beatless, but instead builds on layers and layers of brooding, captivating synths up to an incredibly emotional climatic waves - this build in my experience requires that the set can maintain a composure as the 'drama' continues to unfold, taking care not to sound harsh or congested. Yet again, EA1000 does not disappoint, and I have an overwhelming desire to kick back and completely immerse myself in this utterly spectacular piece of music.



Still Corners - The Trip

Another album I've loved for many years, and this opening track a real favourite. It has a wonderful sense of melancholy, and I adore both the vocals and instrumental arrangement - the opening guitar has such a distinct and gripping intensity. Vocals sound accurate with good body and higher registers are free of sibilance - positioned perfectly centre and a touch forward, with guitars positioned to the left and right, percussion a touch behind and with good positioning with cymbals stretching out giving a great sense of space. A busy enough song, beautifully rendered on EA1000.



Comparisons

OD200 - more of a relaxed presentation and less resolving with a smaller stage, yet I’d class this as all part of the charm of the OD200, it’s the type of set that you can listen to for hours without fatigue. While they both have a nice emotive warmth, EA1000 sounds immediately more spacious with musical nuances far more apparent. OD200 focuses more on mid bass than sub, EA1000 extends deeper with that sub-woofer like experience, where the overall smooth tuning of the OD200 with that mid bass focus tends to result in an overall more intimate presentation.

Project M - at $329, this latest from Dita has created a lot of noise in the community in terms of what it offers from an overall package perspective for a relatively low price - having owned and recently reviewed a set, I can fully agree with the general community feedback so far. What you are getting here is a more neutral sounding set that focuses on clarity which when I switch from one to the other is immediately apparent, EA1000 strikes me as more emotive but steps back on clarity and detail. These offer different flavours really and I could easily see a case for owning both where you might want a more neutral reference style tuning. While EA1000 is a comfortable set to wear, Project M takes the prize here as possibly the most comfortable IEM I’ve ever worn, likewise the wonderfully ergonomic cable is a massive feat in itself. In addition to the more neutral tonality, Project M is also brighter up top, presumably due to the BAs handling the highest frequencies.

TS316 - a step up here in terms of resolution, with an immediately noticeable increase to details and soundstage, the depth of sub bass extension apparent too, and overall sounds more energetic due to a brighter tonality. The TS316 is an easy recommendation at $499, but no more so as the EA1000 at $219, both offering significant value in terms of their performance vs higher priced sets. While EA1000 sounds instantly enjoyable and captivating, TS316 jumps up to being instantly impressive and arguably one of the most competent single dynamic drivers in the sub $1K category.

Conclusion

It’s genuinely hard to say anything negative about this set - as noted in my sound impressions earlier, it’s an IEM that is just very easy to enjoy and in my experience works with any genre I care to reach for. Of course some will want more resolution, or a more exciting music portrayal - we all have our specific requirements in this hobby, but I do think safe to say an easy recommendation for anyone looking for a musical set which has admirable technical capability and offers an all-round ‘safe’ tuning. There are of course 'improvements' in various elements as you step up to sets at far higher price tags, but I would expect that, while at the same time taking the very real notion of diminishing returns into consideration. This is my first from Simgot and definitely exceeded expectations, I can fully understand why these have been so highly praised in the community for many months now, certainly not a 'fly by night' set with fleeting hype, these are in my opinion a real benchmark set in the price segement and above.

Introduction
Simgot is one of a few Chi-fi companies that managed to capture the heart (or the ears) of many audiophiles in the recent year. With their capable, high quality, dynamic driver along with their competitive pricing, Simgot just keep impressed us from their cheap entry level option like the EW200, EA500 to this iems right here, the EA1000.

The Simgot EA1000 house a proprietary purple-gold diaphgram DD along with a very special Passive Radiator, which was a trickle down tech from their older brother, the EA2000. It was said to improved the bass texture and add many subtle nuances which in turn improves the whole listening experience. In this review, i'll dive into what makes this iem special.

The EA1000 has a MSRP of 220$.

*Disclaimer: This iem was a tour unit that Simgot provided for me and my audio group in exchange for our reviews and impressions. I did not pay for this iem. I would like to thank Simgot for giving me this oppotunity.

Packaging

The box of the EA1000 was not as big as i thought. It was smaller than i thought. Here are some pictures of the inside of the box.


Inside the box as you can see, Simgot provided us with: The iem itself, a silver plated copper cable in 3.5mm termination, 3 pairs of tips, 2 pairs of exchangeable nozzles, a few silicone rings of the nozzles themselves

Design/Build quality/Comfort

Similar to the EA500, the EA1000 also has a stainless steel housing with a glossy surface. This makes the iem very prone to scratches and fingerprints. The faceplate on the other hand was a piece of clear glass with some intricate design pattern. Different from the EA500, it was harder to spot the scratches and stuff with the EA1000, which will makes it more appealing. The iem feels very sturdy on hands.


Above are the pictures that shows the outside of the Passive Radiator (PR) and a glimpse of the Dynamic Driver.

The nozzles themselves are detachable. This allows you to change between the 3 pairs of nozzle to be more suitable for your preference.


The cable is a 2-cores OFC silver plated cable. It feels very high quality. It's soft, thick yet not too heavy and not tangly.

Comfort wise, i can wear the EA1000 for many hours straight with no discomfort or hotspot. Isolation is really good with very little sound leakage.

Sound impression:

*Test gear:
- Source: Poco F3, Dell laptop
- DAC/amp: Chord Mojo + Cypherlabs Duet, Ibasso DC04 Pro, E1DA 9038D
- Eartips: Spinfit W1, Divinus Velvet
- Cable: Stock

Tonality: Harman-ish, neutral bright

During my test, i find the EA1000 to be very to drive. Even using only the DC04 Pro has brought me a very satisfied result with the EA1000. The E1DA 9038D on the other hand is too bright, too analytical which makes it the worst pairing with the EA1000. Chord Mojo was like a match made in heaven with the EA1000, since its slight warm, colored tonality is very suitable for the neutral bright, slightly analytical tune of the EA1000. The DC04 Pro and Mojo is what i mainly used during my review.

In this sound impression, i’ll be mainly using the red nozzle as i don’t like the foam inside the black nozzle, which affects the bass texture compared to the red. The black nozzle also sounds a bit brighter. The yellow nozzle on the other hand, it sounds a bit... rougher in its presentation. It also sounds a touch shoutier, more vocal forward and not as wide, which i dont like as much compared to the red.

Bass: 8.5/10

Subbass is gently roll-off, shifting the focus more towards the midbass. The EA1000 overall has a really fast, punchy and tight bass texture. You can actually feel the quality of the driver themselves, judging from their attack, release, sustain and decay. It’s near planar level of speed if i dare say so myself. Together with the PR, the bass just have this very addicting sense of body and layering, but it’s not at the level of real life speaker with a “real” PR yet. EA1000 can easily keep up with those fast pace drum and guitar session without feeling it’s dragging behind or feeling blurry between each notes/hits.

Mids: 8/10

The midrange of the EA1000 is also really good. Lush...is not the word i’d use to describe it. I mean yes, it does have a hint of warm since there are very light bass bleed, but because the bass quality was done so well, it doesn’t feel muddy or bloated. Instead, i’d say the midrange here is clean, clear, bright, hint shouty (very lightly) and definitely not sibilant nor harsh. However, it’s not the smoothest midrange out there.

Simgot really rides on the borderline of making this really shouty with the usual pinna boost like many other Harman-ish iem out there. The EA1000 does lean more towards the upper frequency, where they focus on that vibrancy or high notes one may associate with female vocal. Male vocal sounds fine, more than fine, but it doesn’t have that wow factor or the usual weight of some singer like Frank Sinatra or Michael Bubble

Instruments like violin, flute sounds emotional and lively; piano has a very clear, well definite notes that lean more towards the bright, cleaner side.

Treble: 8/10

Treble is also done well. It’s highly refined, well extended, not overly boosted nor too airy. The being said, they are on brighter side. Cymbal strikes and hihats have good shimmering to it without being too forward and take the spotlight from the bass and midrange. The boosted upper mids and presence region make these instruments sounds sharper, almost metallic but not sounding too harsh. This part here is what affects the most to the overall balance of the EA1000, preventing many high volume listener to fully enjoy the iem without it modded.

Out of all iems in my everyday-carry collection (not that i have many to begin with), it’s sufficient to say the EA1000 is top3 in terms of treble extension and the pure detail it brings.

The treble maybe fatiguing at times, which is why i said i prefered the neutral DC04 Pro or the colored, warmer Chord Mojo over the brighter E1DA 9038D most of the time.

Tech: 8.5/10

While the EA1000 didn’t exactly wow me with its soundstage size (All 3 planes are above average), it does impress me with the imaging, crisp layering capability as well as its resolution.

The highly controlled bass together with the good extended treble, as well as the well layered mids just seemingly contribute to this high level of technicalities.

Timbre is also good, although the EA1000 leaning more towards the analytical, monitor-like timbre instead of a more warm, velvety timbre on a more relaxed sets.

Using “Bubbles” and “Swashers” from Yosi Horikawa, the EA1000 does showcase a very capable dynamic rendering as well as stage reproduction.


Comparison:

Vs Simgot EA500

It’s been quite a while since i last listening to the EA500, but from my memory, the EA1000 has solved the two things that’s bugging me the most with the EA500: Its metallic timbre and the tonal balance. The EA500 sounds brighter and way brighter in its stock form compared to the EA1000. The EA1000, along with its passive radiator, has higher bass quantity which overall makes it sounds way more balance and enjoyable compared to the EA500. Heck, i’d argue that just solving that metallic timbre alone has made this EA1000 a worth-while upgrade from the EA500. Technicality wise, the EA1000 is better than the EA500 in almost every way, in terms of resolution, bass texture, treble sparkliness, the soundstage,...


Vs Tanchjim Oxygen

The Oxygen has a special place in my heart. It was the God Father to the Olina SE - the iem that truly brought me into the audiophile world. I’ve been using this iem the longest in my collection.

Compared to the EA1000, the Oxygen has an overall warmer, less V, more U type of tuning, vocals sound a bit thinner and sounds technically inferior compared to EA1000 in detail retrieval and imaging. Soundstage wise, the Oxygen has a more intimate staging with inferior separation. Bass texture on the Oxygen sounds notably looser, whereas the EA1000 sounds tighter with faster, snappier attacks and transients. The uppermids and treble of Oxygen sounds noticibly less “hot” compared to the EA1000.

That being said, the overall balance of the tuning of the Oxygen along with its more natural timbre still makes it a notable iem in 2024, even if it was released almost 6 years ago. The EA1000 did not completely replace the Oxygen from my rotation, as the Oxygen is still my preferable option when i want to laid back and just enjoy some good ol’ music. The small housing of the Oxygen just make it seems like it’s floating in my ears.

The Oxygen is also harder to drive compared to the EA1000.

Since my version is the old, 2018 version that hasn’t gone through with the driver change, there’s no need to beat yourself and just get the EA1000 instead. If you’re a detail and technical chaser, EA1000 is a worthy upgrade. You’d be more than satisfied with it.


Vs BQEYZ Wind

On the graph, both of these may look similar especially the bass and lower mids, but in real life listening, these two sounds very different.

The Wind has an overall warm tonality with a hint of darker treble. While the EA1000 has a tighter, faster bass texture; the Wind has a bit slower, more mellow texture bass. The Wind just feel like it’s dragging the end of its bass notes, more bass extension if you will, which makes the layering a bit blurry. Both of these iems have a very clear and forward midrange, but i’d say male vocals have more weight to it on the Wind. Treble wise, the EA1000 sounds brighter, airier, more refined compared to the Wind.

Micro details and imaging, the EA1000 takes the win; whereas macro details, the Wind wins just slightly. Soundstage wise, The Winds has a more 3d soundstage with the help of the open faceplate and the BC.

The EA1000 takes the win to my taste, purely because of the bass. The EA1000 just sounds more effortless compared to the Wind. Not to mention, it’s highly depend on your fit in order to feel that BC.

I’m pretty sure my impression regarding the BQEYZ Wind is legit as i’ve use my shortest, widest bore for the Wind in order for it to contact my ears, so which i can “feel” the bone conduction. Even if i press the Wind into my ears, my impression did not change, so there’s that.

Vs Hidiz MP145


The MP145 maybe a planar, but since it’s one of the best planar in the market at the moment in the 200$ bracket, as well as the fact that its timbre is very DD like, i think this is a worthy comparison. Many people also ask me which one they should pick between the 2, so here’s what i think.

Right of the bat, if you have smaller ears, skip the MP145. The MP145 shell is huge, along with its changable screws on the nozzle which increase its width to be around 7mm! That would affect the fit of quite many people.

Tonality wise, the MP145 has a bassier and warmer type of tuning

Both of these iem has a very fast bass, but the MP145 sounds a bit deeper and more rumbly. Together with the less emphasised uppermids, the bass sounds way more apparent and hits you harder. This also let you listen to the MP145 to a higher volume.

Vocal aren’t exactly the strongest point of the MP145, especially when it goes against the clearer and more vocal-focused EA1000. The bass of the MP145 just adds that additional lushness and weight into the midrange. It’s also standout the most in the spectrum of MP145. The MP145 sounds smooth, lusher, non-shouty and definitely less agressive than the EA1000

Treble wise, both iems are very airy, but they have a slight different in presentation. With the song “Silhouette” by Kana-Boon, on the MP145 has more “zing” to the cymbal strikes and hihats, where as the EA1000 sounds sharper, more rough around the edges. Both of these sound natural though.

Soundstage wise, the MP145 sounds a bit wider with just as impressive depth and height. Imaging wise, both of these are on a similar level to my ears. The EA1000 beats the MP145 in overall detail retrieval.

Depending on the preference, one may like more than another. EA1000 may sounds shoutier and too forward for their taste. Where as the MP145 may sounds too bass heavy with not enough uppermids bite. Personally, i like both. I enjoy EA1000 in a more clinical listening session whereas i would enjoy MP145 in a more relaxing session. You will win with either of this iem

The MP145 is also harder to drive.

Conclusion:

Simgot has set a new benchmark on what iem in the 200$-300$ price range should bring. Not just the sound itself, but the overall package and especially its changable nozzles that allow the users to fine tune the iem to their liking. They really knock it out of the park with the EA1000. I’m looking forward to see what they have to offer in the future.

I highly recommend this iem.

What influences earphone sound more – tuning, or technology?

Last month I posted a lukewarm review of the Simgot EM6Ls tuned to match the Harman Curve, so when Simgot offered a pair of new EA1000s in exchange for a review apprehension filled me… would they have the same nasal Harman tonality, and if so how would they feel about another poor review?

I began reading the impressions of others, and surprisingly EA1000 owners claimed they were a very different animal – what grabbed attention was their driver configuration; One single DD and a “Passive Radiator” which I believe is a DD that fires outwards towards the ear, rather than through the IEM nozzle into the ear canal.

There aren’t many IEMs with passive radiators, and anything unique in the hobby catches my attention!

So are the EA1000s just another Harman earphone to avoid, or do they offer something new?

Packaging​

The USD $219 Simgot EA1000s arrive in a small cardboard box, with an impressive range of accessories.

There’s a small carry case of surprisingly supple leather which seals magnetically, an instruction manual, two sets of silicone eartips in three sizes, and two sets of tuning nozzles. (more on those later)

The stock cable is a very attractive silver-plated OFC litz affair, which unfortunately comes terminated in a 3.5mm plug. Given the EA1000 pricepoint I’d have loved a 4.4mm option to be made available.

Ergonomics​

The EA1000s do an excellent job of looking much more expensive than they actually are. Their weighty stainless steel shells with transparent crystal panels provide the feeling of a high-quality item built to last, and the stock 3.5mm cable further accentuates this luxurious effect.

The shells are actually vented in two places to provide pressure-relief, along with the passive-radiator grilles which I’m assuming also leak some noise to the outside. Despite that I find the EA1000s heavy & bulky enough to isolate quite respectably if you’re thinking of using them on public transport.

As for fit I find their smooth, rounded shape greatly aids comfort and I can keep them in my ears for hours without issue. However their weight is fairly significant so if you prefer lighter IEMs you may wish to look at those with resin shells instead.

Sound Performance​

I used a Hiby R6 Pro II set to hi-gain in AB mode with a volume level of 18 to test the EA1000s.
I’m a cable snob who refuses to use 3.5mm single-ended cables, so instead used a fairly basic 4.4mm Penon Globe silver-plated stock cable to make comparisons easier.

The EA1000s are very cohesive with a clear, clean tonality that’s impressively transparent. They’re quite neutral, but unlike many ‘reference’ tuned IEMs don’t flat or boring – instead they’re lively & dynamic.

They do a fantastic job of conveying the coherency of a single dynamic driver, yet deliver most of the technical performance you’d expect from a multi-driver hybrids.

Bass is unmistakably DD-fueled with the kind of impressive texture you’d expect from a dynamic driver, delivering ample thump to make bass dominant genres satisfying – just don’t expect basshead levels of quantity, because Simgot have decided to prioritise neutrality. Sub bass is emphasised a little over midbass, preventing added warmth being injected to keep the presentation sounding ‘clean’.





Shifting to the midrange the priority is clarity over warmth, with vocal articulation being very impressive. There is a slight bias towards the upper midrange but not enough to bother most listeners, as there’s enough lower midrange to provide a pleasing sense of fullness & note weight for male & female vocals.

I was concerned the EA1000’s Harman origins might result in the thin, hollow tonality that’s always made me dislike Harman-tuned IEMs, but thankfully Simgot have avoided that. What I really like is instruments & voices are portrayed to sound quite large on the EA1000s, whereas on many budget IEMs they often feel small & diminished. This also aids EA1000 midrange resolution which is excellent.

Treble on the EA1000s is adequately resolving given there’s no BAs or ESTs, and Simgot have been careful not to overcook the quantity to avoid any potential sibilance. Treble does not feel rolled off however, with sufficient presence even for electronic music.

Given the EA1000’s very capable bass & midrange performance I’d be hard pressed to expect more in this area from just one DD, and if anything would argue Simgot has achieved an excellent balance.

Technical Performance​

EA1000 technical performance is far above the levels I associate with less costly single-DD IEMs.

The soundstage is impressive even by the standards of even fairly expensive IEMs, with surprisingly expansive width considering just two drivers are present. Stage depth isn’t nearly as strong, but avoids being paper-thin as we often see with more affordable IEMs.

Resolution is very solid given the price range & modest driver count, in fact resolution on vocals is quite pleasing but the EA1000’s definitely aren’t resolution monsters like multi-BA hybrids.

Imaging is quite good which may be largely a virtue of the wide stage giving instruments a fair amount of room to position themselves, though I wouldn’t label it pinpoint as the background isn’t quite inky black.

Dynamics are excellent. Sounds really jump out from the background in a pleasing manner, and as someone who’s always felt dynamics go a long way towards a convincing portrayal of real instruments this quality alone helps ingratiate the EA1000’s with me.

Tuning Nozzles​

The EA1000 nozzles unscrew easily, and two additional nozzles which alter the tuning are included. They’re even supplied with a nicely-finished metal holder they screw into – a thoughtful touch.

Silver (stock)

The stock nozzles are made from stainless steel and deliver a very balanced, neutral sound. These are my favourites for most genres.

Silver (alternate)

Also stainless steel, these deepen bass with more midbass in particular added, bringing vocals forward & embodying them with more presence to increase the overall sense of fullness. These are my preferred choice for vocal genres, but the soundstage doesn’t feel as open & there’s a slight loss of transparency.

Gold
The gold nozzles are made from brass which may in itself alter acoustic properties. They sound more airy, but though the stage feels slightly wider the perception of note weight diminishes & some of the lower midrange warmth feels removed. I like these for classical music.

IEM Comparisons​

I compared the EA1000s with several IEMs at hand to get a feel for how they stack up. For reference the EA1000’s required a volume of 18 on the Hiby R6P2.



Simgot EM6L – 4xBA 1xDD (USD $109)



The EM6L’s are physically lighter with shells less rounded, and oddly I find don’t isolate quite as well. However the difference in comfort between them is fairly negligible. Requiring 28 volume on the R6P2 they’re quite a bit harder to drive.

I can immediately tell the EM6Ls are multi-driver hybrids since they don’t sound as coherent but it feels like they’re covering the frequency spectrum more completely.

EM6L tonality is definitely poorer with more upper midrange emphasis leading to an unpleasantly hollow sound, which comes across as slightly diffuse so the centre soundstage image doesn’t feel as solid. The EM6L stage itself feels artificially stretched wider, but is slightly deeper.

There’s common ground in the tuning of these two IEMs, but the EM6L is more strictly Harman-tuned. Interestingly the EA1000s feel cleaner & higher in resolution, and I much prefer them over the EM6Ls.



Tanchjim Oxygen – 1xDD (USD $230)



The Oxygens tiny, to the extent I have difficulty obtaining a decent seal. They’re amazingly comfortable, but heavy for their size to extent they feel about as weighty as the EA1000s. Needing 25 volume on the R6P2 they’re a bit harder to drive.

Mine are the older version of the Oxygens, which have had their nozzle grilles removed.

The Oxygens remind me of the EM6Ls but with an even thinner, more Harman-esque tonality with far too much upper midrange. Sub bass is impressive & reaches quite deep, whereas the EA1000 emphasises midbass more but also adds more lower midrange to make instruments sound more convincing.

The Oxygens sound like single-DDs that are showing their age, with a much narrower stage and a great deal of difficulty separating instruments during complex passages, and often come across as mushy.



Penon Dome – 3xBA 1xDD (USD $349)



Made from resin the Domes are much lighter & hug the counters of my ears better, so comfort is definitely superior. Requiring 22 on the R6P2 they’re slightly more difficult to drive.

I at once notice the Domes’ richer, more forward midrange that is Penon’s hallmark, though they can be a slightly shouty at times with more upper midrange than the EA1000s. The Domes are more coloured but also more involving & energetic, with slightly more bass quantity.

The Domes’ soundstage isn’t quite as wide but is slightly deeper, dynamics are better and resolution is slightly higher too, and they boast superior note weight. Wheres the EA1000s have a flatter reference tuning and are slightly brighter & more cohesive.



Penon Turbo – 6xBA (USD $549)



In the ears the Turbos feel smaller, lighter and more comfortable. Requiring 26 volume on the R6P2 they’re quite a bit harder to drive. I keep all Turbo tuning switches in their default positions.

The Turbos demonstrate much higher bass quantity with more midbass in particular which helps add warmth. Characteristic of Penon their midrange is more forward with much more lower midrange emphasis creating a tonality I definitely prefer, though some could find those forward vocals fatiguing.

Turbo technical performance is in a different class with higher midrange resolution, better dynamics, a blacker background and a deeper soundstage though the EA1000’s is actually wider. I do find the EA1000s more laidback & relaxingly cohesive, but the Turbos deliver a more exciting, powerful sound.

Cable Comparisons​

As always I’m curious to learn how the EA1000s scale with aftermarket cables.

Since the EA1000 stock cable has a 3.5mm termination I instead paired them with a fairly basic 4.4mm Penon Globe silver-plated stock cable as the “default” option, to make comparisons with other 4.4mm cables fairer given DAP performance can change greatly going from unbalanced to balanced output.



Simgot LC7 (USD $69)



Pity this isn’t the EA1000 stock cable, because it sounds like Simgot tuned it with the EA1000 in mind – as such I recommend every EA1000 owner considers purchasing or at least demoing one.

In this fantastic pairing the EA1000 stage deepens, dynamics improve, the midrange resolution increases, note weight is increased and even treble seems more articulated. It almost feels like the cable adds a couple of extra BAs to each earpiece.



Penon Vocal (USD $69)



As expected Vocal is a great budget option for ‘correcting’ the Harman tonality by emphasising the midrange, lower midrange in particular. Vocals definitely come forward with greater weight & resolution.

The presentation feels a bit smoother with treble slightly rolled off though I don’t get the sense important details are lost, the stage feels a touch narrower but deeper as if your listening position is thrust forward closer to the performers.



NiceHCK FirstTouch (USD $89)



I quite like this pairing, and what really jumps about it is how much more resolving the EA1000 midrange becomes – FirstTouch is almost like a baby PW Audio Orpheus in that sense.

The stage feels a tad flatter but slightly wider, however the background is certainly blacker which helps improve imaging and I do notice a bit more midbass which helps make bass feel slightly more impactful.

Treble seems slightly rolled off, but the cable does creates a smoother, more refined tonality.



Penon ASOS (USD $169)



The ASOS has become my basshead cable of choice, for reliably improving IEM bass performance. So it’s no surprise EA1000 bass impact is improved but unlike other cables in this comparison I feel extra sub bass output, rather than simply more midbass.

The soundstage is definitely deeper and even feels slightly taller, the background is blacker & dynamics are improved, and even treble feels more articulate with imaging appreciably clearer in this impressive pairing, though the EA1000’s tonality is affected less than by some of the other cables.



Effect Audio Ares S 4 Wire (USD $179)



As expected the Ares S increases midbass which makes bass feel a bit punchier, tonality is slightly warmer & smoother but thankfully there’s no treble roll off as can happen with other copper cables.

Stage dimensions don’t seem to change much, note weight is a little better and surprisingly imaging is slightly clearer, but dynamics feel a tad muted and I was left a touch underwhelmed by this pairing.

Conclusion​

The EA1000s are a significant departure from the EM6Ls.

I wasn’t sure what to expect from their unique 1xDD 1xPR configuration, but they do a sterling job of delivering single-DD coherence with multi-driver technical performance.

Sounds too good to be true? As always they’re not perfect. Tonality has a bit more upper midrange than I’d like and similarly priced all-BA IEMs can deliver even better technicalities but sound less natural.

However as far as compromises go, for USD $219 it’s VERY hard to do better than the EA1000s – and almost impossible if you’re looking for the sort of neutral presentation they deliver.

Paired with the LC7 upgrade cable the EA1000s sound really good, to the extent I could live with them as daily drivers and be fairly content… which is almost unprecedented for IEMs in this price bracket.

Wouldn’t have called myself a Simgot fan after the EM6Ls, but the EA1000s have completely swung the pendulum the other way. Any company that produces $219 earphones this good has a big future.

These iems have a sonic signature and a quality to them that reminds me very, very closely of my beloved Sennheiser HD800S. I would dare say that these are a sort of iem version of them. No, they are not a sort of "cheaper version", but the sonically "equivalent version", in the sense that the audio quality leaves nothing to be desired compared to the HD800s (except for soundstage -but that is normal, given that they are full size headphones-). I am not saying that the HD800s are bad. In fact, I love them. I am just saying these Simgot EA1000 are THAT good. Happy listening to all!

Introduction​

2023 was the year in which Simgot really showed everyone what they’re capable of.
The EW200 and the EA500 were basically among the most (if not the most) appreciated and discussed IEMs in the chi-fi market.
The EA1000 “Fermat”, featuring a 1DD+1PR configuration and swappable nozzles (with different tunings) are among their latest releases and have already received lots of endorsements from reviewers and customers, so I was very interested in trying them. And here I am, with a pair of EA1000 and ready to share my impressions with everyone.

Disclaimer: the Simgot EA1000 Fermat were sent to me by Simgot free of charge so that I could write an honest review. This review represents my personal opinion on the set and it is by no means a promotional or paid content.
At the time of the review, the Simgot EA1000 Fermat were on sale at Amazon.com for 219$.
The LC7 cable, instead, is available at Linsoul for 69,99$.

Technical Specifications​

• Driver Configuration → 1 x 10mm DD + 1 x PR (Passive Radiator)
• Impedance → 16 Ω
• Sensitivity → 127 dB/mW
• Effective Frequency Response Range → 20Hz-20kHz
• Cable → 1,20m Litz structure high-purity OFC silver plated cable with 0.78mm 2-PIN connectors
• Plug Type → straight gold plated 3.5mm jack connector

Packaging​

The unboxing experience is pleasant for sure, even though the packaging has a sort of “glossy” texture that makes it a fingerprint magnet.
Everything in the box is properly positioned, the accessories are in separate small cardboard boxes and everything appears in a pleasant way, so one can easily tell that Simgot cares about how the product is presented to the customer.
This is what you’ll find in the box:

• The Simgot EA1000 Fermat (from now on “EA1000” or only “Fermat”)
• Two identical sets consisting in 3 eartips each (S, M, L), even though it makes no sense to include two sets of the same eartips
• Three pairs of different nozzles (of which one is already mounted on the EA1000)
• Some spare o-rings to mount the nozzles on the shells
• The detachable 3.5mm cable with 0.78mm 2-PIN connectors
• A gorgeous carry case
• User manuals and a “Fermat gold card” (which is a very funny idea)

Look at the third photo: the packaging really looks a funny face. Hopefully Simgot did that on purpose

Design and Build Quality​

The EA1000 recall Simgot’s house design with a simple yet captivating faceplate design: the Simgot logo is centered on a white background (yet painted with some minimal and very subtle decorations), underneath a solid transparent glass layer, and everything is framed by a golden outline.

The all-metal body of the earpieces make up for a very premium feeling and (hopefully) a very durable set, even though this comes at a cost: being a fingerprint magnet and being heavier than the average resin or plastic shell (pros and cons, I’d say).
As you can see from the photos, and as seen from the packaging, the nozzle filters are swappable and they easily screw in and out with no issues.



In the inner side of the shell we find the passive radiator vent (easy to spot also thanks to its golden grill) underneath the L and R side indication, along with two pinhole vents that prevent pressure buildup issues, whereas the sides are free from any other holes.

Cable​

The stock cable is good to very good. It looks and feels solid, it sports a chin slider and it’s not prone to tangling. I gotta say I have seen some IEMs in these price brackets that come with worse but there are also IEMs sold for less that come with even better cables. The fact that Simgot provided a good cable in the box should not surprise since we’re talking about a pair of IEMs that sell for around 200$, but at the same time I feel an extra-effort could have been done.
Unfortunately, there’s no way to get a pair of EA1000 with 2.5mm or 4.4mm cable, which is a missed opportunity imho.



In that regard, Simgot also sent me one of their aftermarket cables, the LC7, in order to pair it with the EA1000. It’s hard not to love it: it’s thick, it doesn’t tangle, it looks and feels amazing and it also comes with a 3.5mm to 4.4 mm balanced adapter so that one can also use the IEMs out of a balanced output. It’s not really cheap, since it’s almost 70$, but if you are willing to get an aftermarket cable, here you have one (an amazing one, too), even though I think Simgot could include it with the EA1000 for some promos here and there.

Comfort and Isolation​

The Simgot EA1000 are comfortable, particularly with slightly stiffer and longer tips since they don’t have very long nozzles. The stock tips didn’t meet my expectations considering the price, especially because they didn’t provide me with a good seal leading to an inconsistent listening experience. Not only that, the two sets of stock tips are identical, and it makes no sense since it would have been way better to provide two sets of tips with different nozzle diameters or different materials.
I ended up using a pair of KBEAR 07 tips, which are the ones I’ve used to write the review (not because I didn’t like the sound from the stock tips, but because I really couldn’t find a proper and stable seal) and the EA1000 became extremely comfortable for long sessions, also thanks to the fact that the shells don’t have any sharp edge or protruding wing.
When it comes to isolation, I think the EA1000 can do the job on most occasions, but I don’t think this is an IEM to use in very crowded environments.

Sound​

GEAR USED FOR THE TEST

• DAC: Topping E30
• AMP: Topping L30, Fiio A3
• Mobile phones: Samsung Galaxy S7 Edge, Xiaomi Mi A3, Samsung Galaxy S23 Ultra
• Moondrop May’s DSP cable with PEQ=0
• Dongle: Apple Type-C dongle, Truthear SHIO
• Portable DAPs: Benjie S8/AGPTEK M30B
• Other sources: Presonus AudioBox iONE, Elgato Wave XLR, KZ AZ10

Do they need an amplifier?
The Simgot EA1000 don’t need an amplifier because of their low impedance and their high sensitivity. This means they are very efficient, but on the other hand it also translates in some small hiss when plugged to sources with higher impedance.
I think driver efficiency is very important when it comes to IEMs and I really appreciate the fact that I can use these without always carrying a portable amp with me.

Sound signature
The Simgot EA1000 have three slightly different tunings depending on the nozzle that’s mounted on the IEMs (even though everything lays around the Harman Target).
The Golden nozzle has more upper midrange and slightly less sub-bass compared to the stock red o-ring filter, whereas the black o-ring filter takes this upper-midrange and treble focus a bit further while giving some more sub-bass.
Overall, already mounted red o-ring nozzle has slightly better note weight and seems like the warmer and more bass-focused nozzle compared to the others, this also because the others have more upper midrange and treble.

For this review, I am gonna use the silver nozzle with the black o-ring as it’s the one that strikes a good balance between the other filters.

Lows
The sub-bass has very good extension and incredible control, and it’s a very satisfying experience listening to very deep sub-bass sounds with the EA1000.
The bass is impactful, deep, punchy and even though not the most textured around it sounds very natural and doesn’t leak into the midrange.
What amazes me is the outstanding quality of the bass and how clean it sounds: the EA1000 truly mastered bass reproduction, period.

Mids
The mids are neutral with both male and female vocals sounding very good. Particularly, the female vocals are intoxicating, with a lot of energy and intimacy that really make them shine. In some occasions, there is some episode in which the “S” sound become borderline hot, not to the point of becoming annoyingly sibilant but this isn’t a set for those who don’t like some upper-midrange energy, especially because they EA1000 really rule in this region.
Male vocals sound very good too even though slightly more laidback than female vocals ald could be just a tad warmer, even though they are never overshadowed by the bass thanks to excellent low-end control.
Instruments sound very natural, with layering and separation being helped by a good treble extension that provides for a lot of space in which they are precisely distinguished from each other.

Highs
The highs have a lot of details, it’s easy to spot small nuances and the perceived resolution is among the best I have tried. The treble extension is very good overall: there’s a lot of air and sparkle and this leads to a very “open” feeling while still retaining the naturalness one expects from IEMs in this price range, avoiding every kind of harshness one could think about.
For sure, those who are treble sensitive should probably look elsewhere, especially if we consider the EA1000 with the golden and black nozzle (even though the red o-ring nozzle still has some added treble that may bother the most sensitive ones out there).

Soundstage is expansive with nice width a surprisingly good depth, even though height is average.
Imaging is very good with instruments being portrayed right were they should be with high precision.

Some comparisons (EA1000 with black o-ring silver filter):​

Simgot EA1000 vs Hidizs MP145 (Rose Gold/Balanced filter)​

The MP145 were among the most hyped IEMs of 2023, thanks to their very nice technical chops along with the versatility of the swappable nozzles (just like the EA1000).
Overall, the MP145 are bassier and warmer with less upper mids and less treble extension, whereas the EA1000 are more focused on vocals and resolution.
From a tone/timbre perspective, the EA1000 sound more open and natural, while the MP145 sound a bit more closed-in with more warmth and intimacy. From a technical standpoint, instead, the EA1000 outperform the MP145 with better detail retrieval, imaging and separation, even though MP145’s soundstage feels a bit more “cavernous”.
The build quality is great on both sets, but the EA1000 look more “premium”. The stock cable is of similar quality. Comfort-wise, the EA1000 win hands down as the MP145 are very bulky and may not suit smaller ears. Isolation is slightly better with the MP145 in the ears. If there’s one more think that needs to be pointed out is that the MP145 come with a better set of tips, since the EA1000 come with two set of tips that are actually identical and don’t provide variety.

Simgot EA1000 vs KBEAR Believe​

There aren’t many things to say: the EA1000 win hands down.
The Believe really surprised the market some years ago with their outstanding DD quality, but time and further development of the Chi-Fi industry killed them. The EA1000 win in everything: from sub-bass to upper treble extension, the EA1000 outperform the Believe in every part of the frequency spectrum, and they do that with no mercy.
The driver is also more efficient, they are built slightly better and look way more premium, and the overall resolution is ages ahead.
The only thing in which the KBEAR does better is the variety of tips they come with, but they are inferior at everything else.

Simgot EA1000 vs Celest Phoenixcall
The EA1000 are more resolving, more detailed, and also have much better bass quality than the Phoenixcall. The Phoenixcall are tuned in a more “unique” way, with a stronger midrange recession and more elevated low-end, while the EA1000 follow the Harman target and they’re also more versatile thanks to the tuning filters. Vocals sound more natural, intimate and detailed on the EA1000, whereas they can sound slightly unnatural on the Phoenixcall due to their midrange recession.
The soundstage width is comparable but the EA1000 play in a deeper and slightly taller stage.
Build quality is great on both sets, even though they are built of different materials. Design-wise, it’s a matter of personal preferences, but the Phoenixcall look more unique and captivating. Comfort is great on both sets, but the Phoenixcall tend to fit like a custom IEM and provide for a much better isolation from external noises. Both IEMs come with great stock cables, but the Phoenixcall are also shipped with a wider selection of tips that could help with tip rolling.

Simgot EA1000 vs Simgot EM6L
It’s very easy to distinguish them and to guess what’s the more expensive set. The EM6L are warmer with much more sub-bass and less treble extension, leading to an overall more closed-in, more laidback and more relaxed signature. The EA1000, on the other hand, sound more engaging, more detailed, more resolving, with more forward vocals and brighter treble region. The low-end quality differences really draw the line between the EM6L and the EA1000, since the difference in bass quality and control is night and day: while the EM6L sometimes lose bass control, the EA1000 never let the bass leaking in the midrange, providing for a super clean transition from the lows to the mids. The soundstage is more expansive on the EA1000, with slightly better width and height even though depth is what really stands out on the EA1000. Imaging is good on both sets but the EA1000 are even more precise.
Both are very comfortable and well built but the EA1000 look more premium. The EA1000 come with a better cable and a better set of stock tips. Isolation is slightly better with the EM6L in the ears.

Final Thoughts​

The EA1000 are outstanding: they are engaging, resolving, accurate, detailed, with a high quality and controlled low-end and great end to end extension.
It’s really hard to find weakness in the EA1000, expect for the improvable bass textures and the upper midrange glare with the golden and black-oring filter that could make some “S” sound very hot (they don’t become sibilance but the extra energy may bother some).

It was a very difficult review, especially because everytime I put them in my ears I didn’t want to write. It’s very difficult to sit and start describing sound when you start moving your feet and shaking your head, driven by the dynamism and musicality of this single DD IEM.
I am very happy for Simgot: it has been a great year for them and they released true bargains in the Chi-Fi industry: although I don’t know what’s coming next (except for their newly presented EA500LM, which hopefully I’ll be to try), I am sure they have the potential to set new benchmarks in this 2024.

Simgot was kind enough to send in the EA1000 for review, as part of an Australian audio review tour, I wasn't paid for the review, any opinions, thoughts are my own.

Design musings

Development of in ear monitors is accelerating as manufacturers compete for best in class. Single Dynamic driver IEMs would seem to be the most basic design, with products on the market for less than $20. And yet Simgot is selling the EA1000 at $220.

The reason is they have taken the design and developed it to the Nth degree. I don’t pretend to understand what sputter deposition purple-Gold diaphragm technology or dual magnetic and dual chamber technology means. I have an inkling of what Passive radiator technology is designed to do but I will leave others to explain that. What I understand is the sonic results of all this development.

Equipment used to test.

I used my Hiby R3 Saber 2022 DAP with a NiceCHK 2.5mm balanced cable and TRN T ear tips. Listening to my music collection of FLAC files. I get a nice deep seal with these tips.

A note on fit and comfort. In size the EA1000 is similar to the Simgot EW200 with a similar metal body. But for some reason the 1000 fits deeper in my ear canal to the point where the IEM almost seems to sit flush. Everyone’s ears are different, but we have a bit of synergy going on here.
Drivability

I use the DAP set to high gain and when driving 7Hertz Legato or Hidizs MP145 I use a volume setting of 45 (sometimes a little higher) . With the Simgot a volume setting of 35 gives me equivalent sound pressure and boosting to 40 I find unnecessary and no advantage.

The Sound

This IEM impresses from the word go. Its tone is rich and tends to the warm side. The bass is fast, deep and well textured, allowing rumble and thump when required and never intruding on the midrange. Vocals have a forward placement with natural timbre and an intimate expressiveness. Vocal lovers will enjoy the EA1000. Singers have room to move in an expansive space with great left to right width and enough height and depth to create an immersive soundscape.

One of its great strengths is handling complex compositions. Instrument separation is first rate as is detail retrieval. The EA1000 never gets flustered or congested. Each element of a song is audible as recorded and the sound is coherent and compelling. Songs breathe!

Treble details are refined, airy and extended, never too hot or overbearing. Indeed, the cohesive tuning of this IEM is its big strength. And above all its is a MUSICAL IEM.


Conclusion

I titled this review. The Goldilocks IEM

If you don’t know the children’s fable, it’s a story about porridge and a little girl who eats the three bears porridge. Daddy bears porridge was too hot, Mumma bears porridge was too cold but baby bears porridge was just right! The Goldilocks zone!

The Simgot EA1000 presents each aspect of the audio spectrum as “just right” to my ears and I’ll be saving to get my own set. Highly recommended.

Review OF The Simgot EA1000​

Introduction​

SIMGOT has never launched an IEM that was not highly accepted or commended sufficiently for their sound quality for the price they're being offered, whether it be the EA500, EM6L, or any other of their high end or budget IEMs. One of the earliest businesses in the audiophile sector is reputed to be this Chinese enterprise. They were formerly well-known for their EN series, but they have recently resurfaced and launched a few IEMs that audiophiles like me have found to be rather pleasing. I have been interested in this company ever since I heard about their EN series, and since then, I have grown to love their products and the technology they actually uncover with perseverance, hard work, and dedication. Other than SIMGOT, I don't believe I have ever seen a company that is as open about the creation and application of their technology in their goods, which makes sense. It has taken some time, but I was fortunate enough to obtain their most recent model, the EA1000, which is a younger sibling of the EA2000 that has the same technology. I would like to make a few clarifications before sharing my actual findings.

Disclaimer​

*Since this unit tour was organised by the generous people at SIMGOT, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “EA1000.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the EA1000 based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

The dynamic driver of the EA1000 is a 10mm driver with a multilayer sputter-deposition purple-gold diaphragm and a 6mm passive radiator. This configuration is unique to the EA1000. Using the previously mentioned SDPGD technology, the dynamic driver is essentially a second generation dual magnet and dual cavity driver. Its older brother, the EA2000, has the same configuration. Compared to comparable metal-made IEMs, the shells made of premium alloy metal that has been CNC etched feel more robustly constructed. The SIMGOT brand emblem is centered over a white background in a stunning pattern on the faceplate. The eartips allow for an isolated fit, thus the shells' comfort and fit let you to listen for hours on end without experiencing any pain or weariness. The included cable has a higher texture quality and feel than the one that comes with the EA500. The cable contains a 3.5mm straight termination plug on one end and a two pin connection on the other. Three different tuning nozzles, a carrying case, six pairs of eartips in varying sizes, and a variety of red and black rings for tuning nozzles are among the additional accessories that come with the IEM. Regarding the technical details, the sensitivity is 127dB and the impedance is 16 Ohms. There is a 20Hz–20kHz effective frequency response.

The EA1000 exhibits a common sound profile with vibrant, well-detailed, and resolved notes presented with the most precise note presentation I have ever heard from a single DD, yet it leans toward three distinct tunings. Although I am aware that there are passive radiators that help with the notes' natural reproduction and dynamic quality, I still think the dynamic driver is the most amazing. As I indicated, there are three distinct tunings that may be accomplished with three distinct tuning nozzles, enabling the tuning of two in-house targets as well as a 2019 harman target. For my part, I don't see any appreciable differences between the harman and their golden 2023 target—discussed later. Coming to the sound, I am using the standard tuning nozzles (black ringed nozzle) which they came with for more intricate findings. Regarding the sound, for more complex discoveries, I am utilizing the standard tuning nozzles (black ringed nozzles) that were included.The vocals and instruments from the lower mid range to the upper frequencies have a very vibrant and clear response that comes across as joyful and detailed, while the treble sounds pleasantly expansive, airy, and non-fatiguing.The bass feels accurate, slamming, and banging because to the excellent PR that was employed.Even though this is my first IEM to use a dynamic driver and a decent passive radiator, the tuning and sound quality really amazed me. It still amazes me that a single DD can produce a presentation with such forward-thinking, natural sounding quality and exceptional technical ability. Let's examine the sound presentation in more detail.

Treble​

I believe the frequency graph is not accurately depicting the situation because my perception of the response is different from what the graph indicates. If this is not the case, I will trust my instincts first. The problem is that I hear no issues at all. By this I mean that the reaction is deliberate, thorough, and astonishingly brilliant, and I don't have any problems with peak sound or sibilance.I think the singers and instruments sound richer and fuller because of the high treble's wonderful airy extension.Please bear in mind that I am discussing an IEM that costs less than $250 USD. The notes are precise and accurate, but they don't sound piercing in my opinion—rather sophisticated. The singers and instruments are more prominent in the lower treble, which adds additional energy without pushing forward too much to cause a peaky or shouty reaction. The lower treble sounds just as clear and detailed as the upper treble. The instruments and vocals are more prominent but still under control, preventing any metallic tones from being heard. Even when I compare the treble response of the SIMGOT to other IEMs around the EA1000, such as the quintet or Falcon Ultra, I believe that generally, the SIMGOT did the best job of finding the ideal balance between sounding as natural as possible and without being offensive.The quintet, in contrast to the Falcon Ultra, sounds more forward-thinking and aggressively detailed, whilst the latter lacks sharpness. The HYPE2, which likewise generates a smooth response with details that are similar to the EA1000, is the only IEM that I have seen that comes close. As a result, the treble area is presented in an expansive, intricate, and airy manner overall.

Mid Range​

In terms of tone and timbre, the mid range is where the response sounds the greatest; in my opinion, these are the best IEMs under $500–$800. Though I do believe that the placement of the vocals and instruments plays a significant role, I still think it is a great achievement that SIMGOT brought this IEM to produce such a lively response that makes the natural and forward response sound fuller, richer, and detailed at the same time. Many brands haven't come close to this level of performance. My observations stem from the singers' remarkable dynamic leaping throughout the response, which sounds multifaceted and simultaneously detailed, richer, fuller, and unique. When compared to the lower treble, the upper mid range adds more energy to the mix and permits greater clarity. The vocal and instrument tones sound well-balanced, with the instruments complementing the vocals while adding a charming presence when necessary to be more prominent in the mix without overpowering the vocals. The vocals are quite enjoyable to listen to, keeping you on the edge of your seat as they spread out far and wide. makes the temperamental shifts in the mix sound more full.To put it simply, I think the vocals sound the best of all of them. Yet, it doesn't sound as rich or velvety at the same time. When vocally prominent tracks are heard, the vocals occasionally bring out a little "ss." This doesn't bother me too much, but I still feel like I should mention it because the vocals sound more open and lighter. In addition to sounding clean, the lower mid range has good note weight and depth. Similar to how the vocals end on a clear and distinct note, the guitar's bass notes seem slightly thick but not overly dense. I would try the quintet or HYPE2 if I were looking for a more composed answer with fewer inflamed vocals. In my opinion, the Ultra has less open-sounding vocals than the EA1000 and sounds more weighted and real. Overall, the mid range is presented in a more rich, vibrant, and melodic manner.

Bass​

Getting to the bass The passive radiator, in my opinion, aids in achieving the bass's detailed and organic response, which also permits a quick attack and natural note decay, providing a realistic response. The bass is one that doesn't allow for additional prominence in the mix. The quality is sufficient to give the entire response a more sophisticated and grown-up tone. The emphasis is on the sub bass area, which extends nicely enough to provide punches and a deep rumble that aids in delivering notes with impact. Despite this, the rumble seems to be modest and constricted within the ear canal. The well-controlled mid bass produces a meatier presence, enabling both gentle hitting slams and clean, pounding bass. The response reproduces the notes' naturalness, hitting with just the appropriate amount of intensity and weight and resolving at a speed that feels authentic while still taking into account the higher frequency areas. Although the bass is not the highlight of the entire response, it is nonetheless underappreciated since it nails the live stage presentation rather than the concert one. In my opinion, the HYPE2 has a more powerful and thunderous sound than the other model, which sounds more organic and natural overall and amplifies the sound of the bass notes on a large stage. The bass on the EA1000 sounds more textured and sophisticated, even though the quintet sounds smoother and warmer in this aspect than the EA1000. The bass is similar to the Falcon Ultras, however less detailed and textured than the EA1000, in my opinion. In the end, I think there is enough bass response to make the reaction seem lively and enjoyable. As a result, the bass area is presented in a compelling, realistic, and fulfilling way overall.

Technical Performance​

In technical terms, IEMs in this price range sound better on average. Quintet, for instance, has a nicely detailed response with good separation and resolution, but it still lacks sharp imaging. I suppose this is because it introduced sibilance or shouty response. However, after hearing about so many IEMs that were unable to achieve what I believed, all of my concerns were allayed by the EA1000, which exceeded my expectations. Let's get specific.

Soundstage, Sound Imaging & Separation​

The stage is rather large and spread out, which contributes to the surround sound rather than a stereo sound. The depth and height feel significantly better than any other IEMs, though they are similar to HYPE2. The imaging is where the EA1000 excels, as I find it to produce a sharper and clearer response than any other IEM I have mentioned. The notes' separation helps me identify the source of the music because it sounds distinct and far away without being overly dispersed.

Speed & Resolution​

Although the resolution is superb, I think the quintet to be somewhat superior in that aspect. However, the EA1000 sounds extremely expressive in terms of both micro and macro aspects. The notes have a quick attack and fade, and the resolvability seems to time as closely to sounding pleasant and natural as possible.

Sound Impressions​

Tuning Nozzles​

Red Ringed Nozzle - As opposed to the black nozzles, the only complaint I had with the EA1000 was that the "ss" sound was muted, which resulted in a more balanced sound with more male vocal presence and less intensity from the female vocals.Apart from this, I don't see any discernible changes.

Gold Nozzle - The response sounded a little more weighted and the notes sounded denser when compared to the other two tuning nozzles. This helped the vocals sound a little more grounded and beautifully presented, especially the female vocals, but the spark that usually gave the vocals an exciting touch that kept me on edge was gone. However, nothing seems updated or different—only the note weight and density are highlighted. However, I do occasionally think the treble seems a little muted.

Sources​

Sony WM1A - The response sounded larger and more expansive with a more dynamic response when listening to the EA1000 with WM1A. The vocals, especially the female vocals, seemed a little shouty, even if the notes were more rounded. This was probably around the 2-4k range. However, the bass was louder and more thumping. The calmed energy overall, particularly in the treble region, was the only other discernible difference aside from this.

Tempotec V6 - The response was smoother and cleaner while listening to the EA1000 through the V6, but it also sounded more intimate and lively. The energy was regulated because it prevented any focus from being heard in the mix. The details were as they were, but because they weren't as obvious, they were less noticeable. While the voices sounded less open and separated, allowing the response to sound more relaxed, the bass felt more in control and linear.

Conclusion​

To sum up this review, the EA1000 far exceeded my expectations and lived up to the fanfare that audiophiles had for it. Nothing stands out as being particularly incorrect or distinctive from what any audiophile would find pleasing at first hearing. Its opulent feel and sound profile make it the ideal IEM for around $500. Vocal aficionados would adore the EA1000 for its deep and satisfying response that captivates your listening style. I wholeheartedly suggest it because of the response, which sounds as close to a faithful response as possible. Investing $1,000 USD is not necessary to experience TOTL level sound quality; the EA1000 will do the trick.

The SIMGOT revolution is still going strong up to the present on how it dictated last year's portable audio scene as it presents some of the best products that many audio enthusiasts are willing to accept. The EA500 is the testament that you will get an excellent set with good tonal and technical performance at entry-level pricing. And now what I have here is their latest offering at over $200/£160 segment.



This is SIMGOT EA1000 Fermat, it's a single dynamic driver with passive radiator as its supporting implementation. SIMGOT already did implement this configuration before on their EA2000 which is a midrange set. The EA1000 uses the latest generation of dual chambered, dual magnetic dynamic driver with newly-developed composite materials of its diaphragm made of SDPGDT (sputter deposition purple gold diaphragm technology) which is more rigid and better elasticity to deliver a more responsive and deeper bass response along with improved dynamic range and shimmering and crisper high frequencies. The 6mm passive radiator will enhance deeper pitch and darker tone due to better stimulation on resonance effect as it traps those sound pressures.



The drivers were in a solid aluminium alloy with a detachable tuning nozzle as SIMGOT offers three distinctive tuning. The surface of the cavity base shell of this set has a mirror finished surface while its faceplate was laminated with glass-like material to give that classy and elegant look. There are two vent holes in the cavity base part that allows it to escape some excessive air pressure generated from its high-performance dynamic driver. SIMGOT continues to use a proven interlocking mechanism on this set which is a standard 2-pin connector.



The stock cable of the SIMGOT EA1000 is of a high quality as it is a 2-core Litz OFC silver-plated copper that will assuredly deliver an unadulterated audio signal without any distortion and interference that will affect the sound quality. The termination plug is a gold-plated 3.5mm SE to ensure better conductivity and improvements of its corrosion resistance.



As for fitting and comfort, despite that this set shell chassis was made of solid metal alloy, it really rests well into my lugholes without any discomfort or wear fatigue. The passive noise isolation is excellent as it was able to block some noises from the outside due to good sealing.



The product presentation of SIMGOT EA1000 is quite impressive as it gives us some of the best unboxing experience and how the contents and accessories are well-organised inside.




Here are the following contents that were included inside the box:

• Pair of SIMGOT EA1000 Fermat
• Stock cable
• 3 pairs of vocal silicone ear tips in different standard sizes.
• 3 pairs of balanced silicone ear tips in different standard sizes.
• IEM storage case.
• extra 2 sets of tuning filter nozzles.
• Spare filter rings
• Paperwork like user's manual and warranty card.

Power scaling and amplification-wise, with an impedance rating of 16Ω and sensitivity of 124dB, SIMGOT EA1000 is indeed an easy to drive that even a smartphone or tablet with decent power output will be able to amplify it properly. With a decent power output, it utilises a full and dynamic sound that this set is capable of.



To determine its tonality, since it has a detachable tuning filters nozzle, it offers a variety of U-shaped sound profiles that usually aligns with Harman-style of tuning with some deviations.


(Graph was provided by @baskingshark , credits to him)

Silver nozzle with red ring is more of a typical Harman target curve that we accustomed with, while the silver nozzle with black ring is SIMGOT's in-house tuning which is a based of a modified Harman target curve and then on golden copper nozzle with white ring is SIMGOT's latest in-house tuning that somehow rectifies some shortcomings of those tuning target curves to sound more balanced and engaging.




LOWS/BASS:

The bass response of this set is quite well balanced on both sub-bass and then mid-bass given my aversion and criticism in most Harman-style of tuning. While it has good sub-bass presence as I discerningly get its rumble and reverberations from instruments like low tone bass guitars, synthesisers and drum machines, the mid-bass is quite well-bodied on its texture as it delivers a slam, authority and punchy lows which might attribute due to the implementation of passive radiator to give a deeper and darker tone.

Bass guitars sound more sombre and resonant while bass kick drums have eerily and thudding sound, and then on male vocals, bass-baritones seems to projects a decently woolly and dusky vocals but still not deepest nor the darkest tone that I really want but for Harman-type bass response, this is quite satisfactory to my ears.


MIDRANGE:

The midrange presentation of the EA1000 are quite recessed in the overall frequency range but it has clean, transparent and energetic sound that will be more oriented towards female vocals, strings and woodwinds.

Male vocals particularly on baritones and heldentenors appears to sound a bit lean in my liking as it loses some volume and depth as they sound a bit too smooth, less warm and lack of richness. Tenors have bright and dazzling sound as it is more beneficial to leggero and lyric-type tenors. On females vocals, contraltos apparently has lack of texture and finesse as they sound less hefty and less husky sound while the mezzo-sopranos have tender, golden and fiery sound, and then on sopranos, they quite sound very expressive and captivating as they sound shimmering and crystalline.

In regards to how instruments sound with their respective timbre and tonality, strings such as guitars have a crisp and bright sound and violins have lively and vibrant sound. Woodwind instruments like piccolos, concert flutes and clarinets have a brilliant, silvery and lively sound respectively. On brasses, trumpets have brilliant and penetrating sound, horns have clear and metallic sound and trombones have sinister and dramatic sound. As for percussions, snares have sharp and precise sound, tom-toms have resonant but a tad less warm sounding, field drums have hard and majestic sound and kettledrums have resonant and a bit dry sound from it. Pianos have a balanced to tad brighter tone that makes them sound emotive and exciting.


HIGHS/TREBLE:

The treble response of this set is quite energetic and shimmering especially on silver coloured black ring nozzles and silver coloured red ring nozzles. The upper mids and presence part of the treble region are quite elevated on its overall tuning as it gives more definition on female vocals and sharper attacks of instruments. It is also noted that in some instances that some female vocals might sound a tad shrill and shouty but at least the sibilance was kept under control and harshness is barely minimal to none to be bothered with.

On crashing cymbals, it sounds bright and metallic while the hi-hats are a bit too bright with its distinctive buzzing and breathy timbre. Glockenspiels sound shimmering and brilliant, then on celestas, they have this particular “heavenly sound” as its sounds quite glistening and bright. It has a good sparkle and fairly airy treble response for a dynamic driver set with passive radiator.


SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

As for its technical aspects, it appears that the EA1000 has an above average sound/speaker proportions, as it has above-average lateral span, just a decent height and reasonable depth as it is just give me a moderate size headroom as I've experience a more cavernous soundstage from other sets.

The stereo imaging gives me a concave-like soundscape where I can locate precisely the positioning of instruments and vocals in well-separated and well-arranged layers of dynamic and frequency tones from each element. To my surprise, this set is quite capable of handling some of the most complex, multi-instrumental tracks that I'm throwing out on this one.

Coherency of its drivers is quite excellent as it managed to deliver a fast transient response without any distortion or out of phase issues as it performs consistently. Resolution capabilities of this one is fairly competent as it has a good note texture on the macro-dynamics while it has sharp micro-detailing to extract some nuances and detail from an audio track.


PEER COMPARISONS:

ORIVETI OD200

● Probably one of the closest competitors in the market. While it only has a single dynamic driver, it was a beryllium-coated one and it has its own proprietary acoustic pressure technology to support its performance. Just like the EA1000, it has a detachable nozzle system and is also encased in a solid metal alloy chassis, although the OD200's stock cable is a modular one.

● As for tuning, since OD200 also has a detachable tuning nozzle just like EA1000, this set offers two types of tuning, a mild U-shaped sound and a warmer U/V-shaped. Bass quality and quantity on OD200 has more authority and impact but it has slight bleeding across the midrange (silver nozzle mode). Midrange is a tad more warmer and more textured on OD200 in silver nozzle mode that will be beneficial for male vocals, some percussives and mostly on brass section. The treble on both tuning modes on OD200 seems quite different but they all display a merely modest airy extension which makes the EA1000 have more refined treble response.

● Technicality-wise, they are quite comparable but in certain cases, OD200 has a less refined separation and layering aspect, then its micro-dynamics seems to be less detailed but at least, OD200 has a bit more solid macro-dynamics.


DUNU FALCON ULTRA

● A solid offering from DUNU and like the EA1000, it also has a metal chassis and a detachable nozzle tuning system but the difference was that it has only a single dynamic driver and it has their own airflow damping system to improve its dynamics and punchier and solid low frequency. It also has modular cable and offers a lot of types of ear tips to choose from. And also, unlike EA1000, this one has a MMCX-type of connector which is either love or hate.

● Regarding its sound profiles, since this also has detachable tuning nozzles it offers two distinctive tuning, a warmer U-shaped and a bit brighter U-shaped sound signatures. Bass response appears to have a consistent texture and preciseness while a bit lean yet transparent midrange on the blue nozzle while the gold nozzle has some warmth on it and then on treble, blue nozzle filters seem to have more sparkle and shimmer while the gold nozzle appears to have a more smoother and balanced sounding.

● As for technicalities, it has an above average sound/speaker stage but if I compare it closely to EA1000, it has a bit more height. Stereo imaging presents an almost 3D-like presentation within my headroom and it has a good separation and layering. On the resolution aspect, while it has solid macro-dynamics, I noticed its micro-detailing definition seems less sharp.


TANCHJIM OXYGEN (Demo)

● This set is actually one of my most favourite single DD sets under $300 dollars. Like the EA1000, it has a solid metal shell chassis and uses a dual-chambered dynamic driver with CNT diaphragm. But it doesn't have a detachable nozzle tuning filters

● Oxygen has a mild U-shaped sound signature as it has presence of its sub-bass while it is a punchy and articulate mid-bass but compared to EA1000, it will sound a bit less texture. Midrange is well-balanced with clean, energetic and good clarity to give more emotive and expressiveness on vocals and strings instruments. Treble has a good sheen on it with sufficient brightness and has a good airy extension for a single DD set.

● Technicalities-wise, this is not the strongest aspect of the Oxygen as it has an average to above average sound/speaker stage and a more intimate stereo imaging. On separation and layering, if I compare it to EA1000, the Oxygen shows its age that it has less defined layering capability but still it has quite satisfactory capabilities on separation of instruments. On resolution capabilities, it has solid macro-dynamics and good detail retrieval but compared to EA1000, it has less sharper definition.


As I conclude my review about SIMGOT EA1000, This one truly reckons the current state of the IEM segment in under $300/£235 on how this set performs well. The performance of its high dynamic driver along with its well-implemented passive radiator truly defines the tonal and technical performance of this set that will probably change the dynamics of IEM game in the current portable audio market. If you want to experience a prelude to the Mid-Fi/midrange level of sound quality, this set is probably one of them.

The SIMGOT Revolution keeps going on and will continue to strengthen its grip in the IEM market.
