SIMGOT EA1000 Fermat – Warm, Wide And Airy Sound
Simgot Ea1000 Fermat is a 219 $USD In-Ear Monitor or Earphone, with the new SDPGD Technology, detachable nozzles for multiple filter options, and with a beautiful shell that’s made of metal, and a high-end cable included in the package. Today we will review the new EA1000 Fermat and compare it to other IEMs in the mid range price point, including BQEYZ Winter (239 USD), ThieAudio Hype2 (299 USD), and KIWI Ears Quintet (219 USD).
Introduction
Simgot decided to go all-in with the new series of IEMs, and the EA1000 Fermat is the upgraded version of EA2000, which was actually considerably pricier than the EA1000, so this time around a company decides to price the upgrade version considerably lower than the one beforehand. The company is known for their high-quality IEMs, good support, and interesting product offer, although they mainly deal with products in the entry-level range and are not known for flagships. As an Amazon Influencer, I earn from qualifying purchases, and using the purchase links in my reviews helps me maintain this website and YouTube Channel.
I’d like to thank SIMGOT for providing the sample for this review, in exchange for my honest opinion. This review is a description of my personal experience.

Build Quality/Aesthetics/Fit/Comfort
With a new IEM comes a new design, and EA1000 Fermat has the SDPGD technology inside, which is basically supporter deposition of Gold on the diaphragm, which results in a high rigidity, light weight, and a beautiful purple gold color, although we can’t really see the driver diaphragm on the EA1000 Fermat from the outside. To match with this diaphragm, we have a DMDC dynamic driver, which is a dual magnetic and dual chamber driver, having an enhanced flex, and improved control, for a better sound.
Besides the dynamic driver, we have 1 PR Passive Radiator composite driver, and the company offers us three sets of tubes to tune the EA1000 Fermat and give it multiple sonic presentations. This is one of the first IEMs this year for which I did not feel the need to replace the default tips, as the ones they come with have a stickier silicone that works well for my ears. The Passive Radiator is there to improve on the low-end texture, frequency and ambient dispersion, basically to give a bit of texture to the bass.
The cable included in the package is a High Purity Silver Plated OFC Litz Structured Cable. The version I have comes with a 3.5mm Single Ended cable, and as far as I know, it is not possible to order the EA1000 Fermat with a balanced cable at this moment. The IEM shells have a really beautiful design, with glass panels, which add a bit to the weight of the EA1000 Fermat. The cable is detachable and based on the 2-Pin connector, allowing you to replace it if need be. The cable is somewhat rigid, but does not conduct microphonics, and the ear guides are soft, allowing for support, but not hindering the comfort in any way. The medium tightness braiding allows for no tangling when storing the EA 1000.
Subjectively, this is a comfortable IEM, the inner design has no sharp edges, no corners, but a smooth, rounded belly, which finds place inside of your ears quite easily. The IEM shells have a huge ventilation port on that belly, so you can expect zero driver flex and void, but also almost zero passive noise isolation, and I can hear sounds in my room, myself typing on my keyboard as if I was not wearing IEMs at all. There is not a lot of leakage, so you don’t have to worry much about using EA1000 Fermat with sensitive people in the room.
To drive the EA1000 Femat I’ve been using a selection of sources, including Shanling UA4, FiiO Q15, FiiO K11, FiiO BTR15, HIFIMAN EF600, FiiO K9 PRO ESS, iBasso DX320 MAX TI, and Hiby Digital 300. All of those can drive the EA1000 just fine, it is an IEM not sensitive to noise, either background noise or hissing, allowing you to hear music clearly regardless of the output impedance of the source. There is not a lot of scaling with the source, so you can expect the sound to be fairly stable across all sources, regardless of the price and tuning.
Sound Quality
For this review I have used no EQ, and the default filters that come in the package with the Simgot EA1000, to get you an impression as close as possible to your default experience. The signature of EA1000 Fermat is wide, warm, airy, with an excellent resolution, and overall clarity. The sound is slightly slow in the transient response at the bass level, allowing for a longer, sweeter bass note decay, but it is quick and snappy in the midrange and the treble, although I would call it grain-free, it is fairly fluid and clean. The tonal balance is natural, there is a natural amount of bass, a natural amount of voices, with a bright treble, creating a sound that’s similar to a live experience or a concert.
Starting with the bottom end, the bass extension goes as low as about 40 Hz, and that is where the sub-bass starts, with most of the bass energy being focused on the 60 Hz – 90 Hz range. The upper bass suffers a recession compared to the mid bass, which keeps the veil away from the sound, and allows voices, instruments and most of the midrange to shine without too much warmth. This being said, there is still a bit of midrange warmth present in the sound, as the bass is tuned quite forward, and you hear the bass guitar, and bass notes as a forward element of the sound with the EA1000 Fermat.
Male and female voices take a step back compared to the bass, and male voices in particular tend to be recessed and distant, while female voices, guitars, and pianos have pretty much the perfect spot in the soundstage and presentation. The midrange has a quick, snappy, transient response, it sounds clean, vivid and clear with exceptional impact. Lead guitars take a place in front of the voices, while background guitars are pushed in the back, taking a step back and being projected as background for the soundstage. The sound is fairly wide, and fairly deep too, each instrument gaining an entity-like presentation, being separated, and played individually rather than all of them being smeared and combined together. You could say that the midrange sounds rich, having the ability to paint complex songs really well.
With a fairly bright and sharp treble, you can expect detail and resolution to be revealed nicely, and you can also expect to hear intricacies with micro-detail, and textures in the upper midrange to be evident. This being said, EA1000 Fermat is not fatiguing, and it is grain-free, and harshness-free, having just the right amount of texture to reproduce instruments, but not adding more than you’d expect with that instrument. The soundstage gets compressed at louder volumes, it it stays wide and open all throughout, and the best sound can be found at medium volumes, where you can hear both the resolution, clarity, impact and depth of EA1000 Fermat without being cornered to think about them as too shy or too aggressive.
Comparisons
Simgot EA1000 Fermat vs BQEYZ Winter (219 USD vs 239 USD)
Winter is an IEM that I actually have reviewed in Winter this time around, while EA1000 doesn’t have a favorite season to shine. Both IEMs are made of metal and both are about equally heavy, both are resistant to scratches, and I have used both outdoors, with neither having scratched during the time I’ve been using them. The cable that comes with the EA1000 is of a better quality, and so are the tips, while BQEYZ Winter offers more passive noise isolation, but more leakage too, thanks to its semi open design. Both IEMs are free from Driver Flex, but Winter is a bit more sensitive to source noise, and easier to drive, showing both volume and noise quicker than the EA1000 Fermat.
The sound of the Winter is more relaxed, smoother and leaner than that of the EA1000 Fermat, and while you could say that BQEYZ Winter doesn’t focus on details, resolution and clarity, while EA1000 does focus on resolution, clarity and has better revealing abilities for all instruments and music styles. I prefer the EA1000 for slow rock, ballads, and rock in general, while Winter works well when I am stressed and need to relax a bit.
Simgot EA1000 Fermat vs ThieAudio Hype2 (219 USD vs 299 USD)
Thieaudio hype2 is an IEM with a resin body, and with an ergonomic design, it is lighter than EA1000 Fermat, but the cable of the Fermat is of a better quality, although both IEMs come with 3.5mm Single Ended Cables. Hype2 is more sensitive to noise, and needs a better source to sound good, it will reveal a source with a high output impedance rather easily compared to EA1000, which works well even with desktop amplifiers and never shows any kind of noise. The package of the EA1000 Fermat is more complete, it comes with filters, better tips.
Sonically, EA1000 is a warm, wide and big sounding IEM, while Hype2 has a similar presentation, both have a bit of extra oomph in the bass, both have a bit of extra air and sparkle in the treble, and both IEMs have that nice amount of energy for EDM and contemporary music. I prefer the sound of EA1000 for slower music, and Hype2 can show a bit more grain and harshness, while EA1000 sounds more relaxed, more refined, and has the advantage of that mature, cohesive sound. EA1000 has more character and sounds more colored than hype2, as ThieAudio will only pull back the midrange, but the warmth and specific airy, wide sound of EA1000 is present with all music. Go with Hype2 if you prefer a sound that is more transparent, and don’t mind a bit of extra grain, and don’t mind the simpler package, lower quality for the cable and tips, and go with EA1000 to get a better package, a warmer sounding IEM, with more mid bass, and a grain-free sound that is a bit more cohesive.
Simgot EA1000 Fermat vs KIWI Ears Quintet (219 USD vs 219 USD)
The build quality of the Fermat is better than that of the Quintet, and this is easily visible when you hold them side by side, with the Quintet feeling well put together, but sporting a mid quality cable, and a very basic inner design. Both are comfortable, and the Quintet offers much better passive noise isolation, having no leakage at all, while EA1000 is more of an open IEM and won’t isolate much from the outside noise.
Sonically, the two IEMs are different, Quintet sounds more intimate, colored in the tuning, it has a pretty good bass, having most of the bass higher than EA1000, while ea1000 starts with the bass higher up in the frequency response, and instead creates a wider, warmer, bigger bass, with more authority. The midrange is clean for both, but EA1000 has a more natural midrange, better emotion and more depth for both male and female voices, EA1000 handles complex music with a lot of layers better, presenting more information in the background. The treble of EA1000 is brighter, sharper and reveals more information while the treble of the quintet rolls off faster, and although it is also sharp, it is not quite as clean and has a bit more grain. Since Quintet is a colored sounding IEM, I recommend EA1000 more, it should be easier to pair and match with most music, while Quintet should be tested before purchase, to make sure you can handle its specific coloration.
Value and Conclusion
For the price of 219 USD, Simgot EA1000 offers a reliable build, a detailed, wide and airy soundstage, combined with a good selection of tips included in the package, being one of the most compelling overall IEMS in price / performance ratio in the midrange that I’ve heard.
At the end of the day, if you’re looking for a wide, airy sounding IEM, with a refined sound, high dynamic range, and with a stable, distortion-free sound, which is not source picky, but can paint your music in a pleasing tone, Sigmot EA1000 Fermat is a fully recommended purchase today.
