Simgot EA1000 "Fermat" In-Ear Monitor

Introduction:

Simgot has consistently strived to redefine the landscape of single dynamic and hybrid driver IEMs with remarkable success. Priced at $219.99, the Simgot EA1000 is a 1DD+1PR that delivers a more complete and precise high-quality sound, greatly enhancing your listening experience. Combining a 10mm full-range dynamic driver with a 6mm lightweight composite diaphragm, Simgot promises a more responsive full range of drivers and helps maintain stability and driveability.




Build Quality and Accessories:

the Simgot EA1000 features a robust 3D-printed resin body and CNC machining, ensuring longevity and ease of use. Accessories include six pairs of silicone eartips, three tuning nozzles with rings, a high-quality silver-plated OFC Litz cable, and a protective carrying case.




Tuning Nozzles and Versatility:

The Simgot EA1000 stands out with its three tuning nozzles, each offering a unique auditory experience, allowing users to tailor the sound to their preference:

- Silver/Black Nozzle: Adheres to Simgot's Classic curve, providing the brightest tuning with the thinnest note weight. Ideal for trebleheads, though potentially harsh for those with treble sensitivity. This setting maximizes the IEM's technical capabilities.
- Silver/Red Nozzle: Follows the Harman 2019 Target curve, representing the most balanced and warmest sound among the options. This nozzle enhances the lower frequencies for a richer bass and midrange, coupled with smoother upper midrange. However, I find bass to sound bloomy and slightly hazy here.
- Gold/Red Nozzle: Implements Simgot's Golden-2023 Target, subtly enhancing the upper mids to bring vocals forward without excess brightness. The midbass is slightly less pronounced compared to the Silver/Red nozzle, offering a cleaner and tighter bass response. However, it might sound shouty to some with narrow-bore eartips like Spinfits or final E.



Included Eartips and Recommendations:

During my testing of the Simgot EA1000, I experimented with various eartip options to gauge their impact on sound quality and fit. Here are my findings:

• Stock Eartips: The stock eartips provide a well-balanced sound signature, with punchy bass, clean mids, and crisp highs. However, achieving a consistent fit was challenging, requiring frequent readjustments to maintain a proper seal. Upsizing to the large size offered some improvement, but issues persisted. Including a broader range of eartip sizes could help address this fit challenge in future models.
• Pentaconn Coreir Eartips: My recommended eartips for the EA500 LM also bring notable benefits to the EA1000, enhancing the richness in bass texture, upper mids, and treble. Not to mention, the improvements in fit is also immense. The "perceived" benefits can also be measured by my measuring rig. Refer above for the FR measurements comparison.
• Epro Horn Eartips: These eartips lend a blanket of warmth over the sound while maintaining a smooth and relaxing presentation. They are ideal for listeners who prefer a more subdued sound profile. However, some may find the sound slightly hazy with these tips.
• final E Eartips: These eartips add midbass warmth and punch while smoothing the treble. If you find the EA1000 still too bright for your taste, even with the silver/red nozzle, the Final E eartips are worth trying. They effectively smooth the brightness without sacrificing the clarity and detail that make the EA1000 stand out. However, I find upper mids to sound a bit too forward with narrow bore tips on the ea1000.

The Simgot EA1000 distinguishes itself with a bright-Harman sound signature that balances energetic dynamics with an expansive spatial presentation.

The EA1000 delivers a balanced sub-bass that extends well without overwhelming the mix, providing just enough rumble to enhance the listening experience across various genres. The mid bass is textured and slightly warm, particularly with the Red nozzle, which adds a bit of richness to the sound without muddying (too much) of the acoustic performances.Midrange performance varies across the spectrum; while the lower mids appear somewhat lean, the higher midrange is energetic, though possibly at the expense of fuller-sounding male vocals. Female vocals, on the other hand, benefit from the EA1000's tuning, sounding natural and detailed. The treble is where the EA1000 shines, offering detailed and airy highs.

Technical Aspects:

The Simgot EA1000 excels in technical performance, offering a soundstage that is wide and tall, with above average depth. The EA1000's imaging is sharp, with macrodynamics that accurately place instruments across the soundstag.Detail retrieval is excellent too for the price, ensuring that nuances are well-presented without being overshadowed by the IEM's musicality. Instrument separation, layering, and microdynamics are standout features of the EA1000, rivaling and often surpassing much pricier options in the market, making it an exceptional choice for discerning audiophiles.

Drivability:

The EA1000 is easy to drive. It pairs well with anything from smartphones to higher-end sources without needing serious power, making it a hassle-free pick for any listener.



Selective Comparisons:
Simgot EA1000 vs Simgot EA500 LM


The Simgot EA1000 represents a significant leap over the EA500 LM, particularly in terms of technical performance. Where the EA500 LM can occasionally feel compressed, the EA1000 delivers a marked improvement across all technical aspects. Its soundstage, while still intimate, is perceptibly broader, and its treble extends with a crisp and airy quality that breathes life into every track. The bass on the EA1000 not only goes deeper but is also more textured, offering an immersive listening experience.Another notable difference is in drivability. The EA500 LM requires a bit more power to unleash its full potential, whereas the EA1000 is easy to drive. It performs optimally even with minimal amplification, making it versatile across a range of listening devices.

Simgot EA1000 vs final Audio a5000


Comparing the EA1000 to the final Audio a5000 reveals distinct sound signatures. The a5000 has a drier, leaner timbre with a V-shaped sound that emphasizes a speedier and more dynamic presentation. Its bass is warmer, stronger, and reaches deeper, while the treble is noticeably sparklier and snappier—though it can sometimes appear splashy to sensitive ears.The soundstage on the a5000 is broader and more expansive, with imaging that, while wide, lacks the sharpness found in the EA1000. Vocals do not feel as intimate or focused as with the EA1000, which excels in midrange clarity—making it superior for vocal-centric music.In terms of power requirements, the a5000 needs more power to get to the same volume, but similar to the EA1000, it does not require an amp to sound its best.



In Conclusion:

the Simgot EA1000 stands tall as a powerhouse in the sub $300usd IEM market. It's a great example of Simgot's pursuit of innovation and acoustic excellence. The remarkable technical prowess the EA1000 brings to the table makes it a great choice for audiophiles who demand nothing less than good technicalities.

The Simgot EA1000 Is Not Just "Another IEM"; It Is a Clear Statement of Simgot's Prowess In The IEM World ​

EA1000 has been one of the IEMs that I have been very curious to try since its release. Although the initial hype already died out, it doesn’t mean that it’s not relevant anymore. In fact, any newly released single DD that is around 200 USD is put against EA1000. Good gear is eternal after all. Coming at 219 USD, EA1000 Fermat isn’t exactly Simgot’s flagship, but it already overshadowed EA2000 Boson and the others with the positive reception.

Disclaimers​

Simgot EA1000 Fermat was provided to me by Simgot for free and I only paid for the customs fee. As I always say, everyone is biased one way or another so take everything you read with a grain of salt. Also I will try to be more concise and to the point in my reviews from now on without worrying about the word count etc. If you have any questions, please ask me in the comments and I will try to answer them to the best of my abilities.

Build and Accessories of Simgot EA1000​

I think at this point, everyone is pretty familiar with Simgot IEMs high build quality. Shells are, as always, fully made out of CNC’d metal. But there are a few twists on EA1000 that solidifies its place as Simgot’s best offering. Faceplate has a beautiful pattern and a glass cover on top of it, so I can’t exactly call it a fingerprint magnet anymore. On the inner side there is a big vent placed on top of the passive radiator. Yes, the EA1000 has a passive radiator per side apart from the dynamic drivers.



The unboxing experience of EA1000 is also above its brothers. The box is slightly bigger and fancier than usual. When you open the cover inside, you are greeted with a card that explains Fermat’s last theorem and which also acts as a warranty card. The carrying case you get with EA1000 is also fancier. The provided cable is again a single 3.5 mm terminated single ended one but this time thicker. This time you get two sets of eartips instead of one, unlike EA500s and EM6L.



EA1000 comes with 3 pairs of tuning nozzles. Among them silver nozzles with red rings were the most balanced ones, so I used them mostly during my test.

Sound of Simgot EA1000​

Tonality​

EA1000 targets the bright kind of Harman curve like most of the other Simgot IEMs. So if you used other Simgots like EA500 before, EA1000 will both feel familiar but impress you at the same time.

,

Bass on EA1000 is the most distinguishing feature of the set. It’s one of the most defined and well-textured bass I’ve heard around this price range. It’s not exaggerated, just slightly north of what I would call neutral. It doesn’t dig too deep into the subbass either but it’s enough. There is enough warmth without muddying mids too much. Decay is on point, not too fast to feel dry but fast enough to not feel sloppy.



Mids are, in classic Simgot fashion, highlighted, especially the upper mids. For some, I can see it being shouty or intense. Still I mostly like this kind of presentation, and I think most female vocal lovers will like it as well. However, I also think Simgot could provide nozzles that are tamer instead of more intense.



Treble is again pronounced and colored, but in a tasteful way. I mostly prefer bright tuning to a darker one if it’s not too peaky or piercing and EA1000 is definitely not that. Again, a more tamer nozzle offering could make these IEMs appeal to a wider audience. Also I feel as though EA500LM was easier to listen to because the higher bass level was balancing out the treble nicely even though it measures brighter.

Technicalities​

Simgot IEMs have always been among the most technically adept products in their price range and EA1000 is no exception. If you think EA500 is good, wait until you try EA1000. Yes, sparkly treble helps with details that it feels like cheating but if making a bright IEM was enough to be detailed, everyone would go for that sound signature. Simgot uses good parts and it pays off. Treble is more controlled than similarly tuned IEMs, even Simgot’s own.



Headstage on Simgot is very three-dimensional and I don’t use this word too often to describe the headstage/soundstage. It feels spacious but more than that it feels immersive and on point. Neither depth nor width feels more exaggerated than the other. Imaging and layering is very precise. Timbre is mostly great too.

Comparisons​

Simgot EA1000 (Silver with Red ring) vs EA500LM (Gold Nozzle)​

• EA500LM’s bass is slightly more impactful but EA1000’s bass is impactful enough and more textured. EA500LM also extends deeper into the subbass and rumbles more.
• Vocals are clearer on EA1000. The EA500LM has slightly more body and note weight.
• Both are bright IEMs and have similar intensity and tendency to sibilance in the upper mids and lower treble but EA500LM has slightly more energy in the mid treble and above so cymbals and hi-hats are more splashy, still it’s balanced out with more bass. On the other hand EA1000 still feels more controlled.
• Headstage of the EA1000 is more spacious and three-dimensional. EA1000 is also more resolving. Even though the EA500LM has more air, the EA1000 feels more effortless. It renders and layers better. Both have great imaging but EA1000 staging helps its imaging more. Timbre is great on both. If EA1000 was just an EA500 with a passive radiator, that would explain bass detail and texture but obviously it’s more than that.

Simgot EA1000 vs BQEYZ Winter​

• EA1000 is bassier. Bass on Winter is fast, tight but not as impactful. Subbass extension is also better on EA1000.
• Vocals are more forward on EA1000. Winter is kind of in the similar vein but vocals are more natural and in line with the rest of the track.
• EA1000 overall brighter but Winter has some emphasis where bone conduction driver kicks in. Above 6k Winter emphasizes “S”s, “Sh”s and “T”s slightly. Male vocals are more likely to get sibilant on EA1000 with volume while females get sibilant first on Winter.
• Both have great detail rendition. EA1000 pushes the detail more in your face however, so if you are after the ultimate detail between the two, EA1000 wins. On the other hand Winter has a deeper head stage and imaging more precise. I like the timbre on Winter slightly more as the EA1000 can get a little metallic compared to that.

Conclusion​

When I review a Simgot product, even I question my own objectivity. But they almost always deliver what I look for in IEMs. In EA1000 Fermat’s case, it provides a very balanced and highly technical listening without any balanced armatures, piezoelectric or planar magnetic drivers. I never could feel comfortable with multi driver IEMs as much as I did with single DDs, maybe that’s why I’m biased. With a Simgot’s single DDs, you don’t feel you are missing out and EA1000 is the ultimate form of this experience. The only criticism I can give is that they could make the alternative tuning nozzles in a way to appeal to the treble sensitive audience too. Other than that, I have no complaints and definitely going to keep EA1000 Fermats.
