Build, Design & Ergonomics

The quality of the build and finish would be spectacular at almost any price point for an IEM.
The IEMs themselves are almost fully metal and on the heavier end of the scale. Each unit is engraved with the word ‘fermat’, and either the letter L or R, and yes, these letters are engraved, I checked.



The faceplate is coated in glass, which is as you’d expect as eye-catching as it is difficult to keep perfectly clean.

Provided are 3 different types of exchangeable nozzles which I think are machined extremely well. They are very easily screwed-on or off and difficult to over-tighten with the provided silicone o-rings: more on the differences between the nozzles later.

The silver cable is an improvement over the lower end models. The bulk of the twisted part of the cable is highly tangle resistant, however after the Y-split, I found that the two cables were quite prone to twisting and tangling, although not particularly more than average.

The cable is also finished with what appears to be a shiny metallic ribbon. I’ll leave the final decision of taste to the individual, but I can honestly say that the whole product, in all it’s gaudiness, does have a significant wow-effect like a piece of shiny jewellery that is accentuated by it’s carry-case that also has the appearance of a small jewellery box.



The case appears to be identical to the one provided with the EA2000, so it has three holders for the exchangeable plugs that are not present in this model. I don’t have a problem with this personally as they are sibling products.

Provided are also two identical sets of silicone tips and a velcro cable tie.



Each IEM houses a single 10mm dynamic driver with a vapour-deposition coating of purple gold. Purple gold is a gold alloy with a ratio of 79% gold and 21% aluminium and this is as far as I know the first instance of it being used as a driver coating. In my experience, gold vapour deposition coated drivers have been involved in some of Ultrasones better sounding headphones (yes I do realise that is an oxymoron for some of you), and since purple gold is lighter than gold, I had some biases or expectations going into this.



Paired with each driver is a passive radiator. I didn’t find any documentation in the box or online about the size of the passive radiator, but looking at the CAD pics online and measuring the vent size, it appears to be 5mm.

I found that these IEMs fit better than the EM6L and fit my ears better than average, but I also found the stock tips useless for my ears. In the end I settled with some tips that I believe are from Linsoul, however I don’t recall the exact model.

Other than that, the wearing comfort was above average despite the added weight.

The Sound

The tuning of the EA1000 from an engineering point of view was something I was very excited to experience. The concept of passive radiators in a listening device is not a new concept. They have been used in loudspeakers at least starting in the 1960’s, let me know if you know any earlier models, and in headphones the most famous example is the 1975 AKG K240 Sextett, with it’s 6 passive radiators. Now I get to hear it in it’s miniaturised form.

The acoustic effect to my ears presents music quite differently to other more traditional IEMs.
Compared directly with my JVC HA-FW1800, the JVC gives that more traditional, direct, accurate, in-your-head IEM sound.
The EA1000 has a sort of forced holographic quality to the sound, especially horizontally.



There are elements of music that appear to be spaced very differently. I think the stereo image might be a little broken or diffused.

This becomes very apparent when playing 3D video games, which actually was a very jarring experience, with most sounds appearing to be coming beside me or from behind, even when they were happening ‘in front’ of me in 3D space.

For normal stereo music however, this IEM does a very tasteful job of taking the stereo mix and spacing it out in an almost ethereal way.
It’s not a purist sound or technically accurate, but it is mostly very enjoyable, and in my opinion has succeeded in doing something unique in trying to take the listener out of that closed headspace and into something bigger.

Red = Red O-Rings
Grey = Black O-Rings
Orange = Copper Filter


Regarding the purple gold vapour deposition coating, I can’t tell if it’s changing the sound. We do know that this technique has also been used in headphones since the 1980’s when the biggest Japanese brands fought to put the most exotic material coatings on their drivers, including sapphire, ruby and diamond, to increase the rigidity thereby reducing distortions in the driver surface.
In any case, every time you change nozzles on this IEM, you may catch a glimpse of the alluring purple gold coating, which is at the very least something to smile about.

Moving away from the abstract, I never felt wanting for resolution or transient response. Technically the drivers are doing an awesome job of digging out detail in recordings and even have higher than average separation, which they absolutely should have at this price point.

Timbre and tone is definitely on the brighter side, with vocals being pushed quite far forward due to the elevated area around 5 and 6KHz.
My ears hate ear-canal gain, so pulling this area back around 5dB with EQ brings these back into a ‘normal’ tuning, after which timbre is excellent. I’ve always been a big fan of single dynamic driver IEMs which often offer a far more homogeneous sound compared to mixed transducer IEMs or headphones.

Bass is still just a hairs width into bloomy territory and treble is also a margins width into the splashy zone, so it’s not perfect, but neither do I believe that was the goal of this IEM to begin with.

Passive isolation is the only part of this IEM that I would consider a weak point, as it is average at best.



Now onto the interchangeable nozzles: they do two things.
Firstly they reach three unique acoustic targets. That’s very simple to understand, with the biggest changes occurring between 2-3KHz and 5-6KHz.
Secondly, the way these nozzles do this is with the use of physical acoustic filters, or lack thereof, which brings me onto an important tangent.

• The black o-ring filters use foam to tune the sound.
• The red o-ring filters are fully open nozzles without any acoustic filter.
• The copper coloured nozzles appear to use a thin piece of fabric with a hole in the middle.

The most important difference for me personally was between the red and copper, and the black.
The black nozzles, filled with their foam, totally alter the presentation of the IEM, going from that uniquely crafted holographic space, to the ordinary in-your-head, boring, traditional IEM presentation.

The ‘emptier’ copper and red nozzles both preserved the unique sense of space and staging that makes these IEMs so different.
I would go as far as saying that the black nozzles ruin the sound.
Of course on paper, it doesn’t appear that way, but the squiggly lines never tell the whole story.



In the end I settled on the copper nozzles with their fabric donuts.
These preserved the holographic aspect of the sound and at least to my ears, provided a bit more bass texture, while taming some aggressiveness in the treble.

In the end I found that tuning the IEM by EQ was far more productive, however it was also not without it’s limits.

Comparing the EA1000 again with the JVC HA-FW1800, which follows a very similar tuning philosophy, I found that that the EA1000 does not take kindly to a bass boost.
To my ears, both IEMs suffer from a slight lack of sub-bass slam.
The JVC takes EQ like an absolute champ, blasting out relatively clean, thunderous bass well into the excess.
The EA1000 unfortunately gets quickly bloated and instead of churning out a deep slam you get thick mud.



But let me be clear; the stock bass tuning, texture and presentation is already almost perfect. I think most people would only be concerned with EQ’ing the upper midrange and maybe the treble tuning.

Conclusions



Build quality – check.
Ergonomics – check.
Objective sound qualities – check.
Objective tuning – mostly check.
Subjective sound presentation – this is where I draw the line on giving a full recommendation.

There will surely be people who do not like this, because it is deviating from the objective truth.
I can only give full recommendations on products that I believe have the highest chance of pleasing the most ears from a subjective and objective perspective.



So while I think the acoustic presentation of these is really special and truly enjoyable in the way it makes music more alive and even euphoric, particularly in it’s presentation of vocals and upper mids, I think depending on the type of music recording or other tasks it may be given like video games or TV, there may be people who actually become dizzy from it.

Even I found that with some specific electronic music tracks, because I couldn’t quite place the stereo-image in front of me, my brain found dissonance between reality and expectations and I almost got something close to motion sickness, which was very quickly remedied with a different piece of music.

I also might be an outlier, since I also easily get VR-sickness after 5 minutes of gaming but it might be something to look out for.

Otherwise, I’ve been seriously enjoying using these over the past few weeks and they get a solid recommendation as a IEM that is bravely doing something really quite different and fun, in style.

Bass:
The EA1000 has average bass that allows the hits of a drum to be decently dynamic and impactful but remains snappy and fast in terms of decay. I could see that Simgot attempted to go for an engaging, but still neutral level of bass for the iem. However, I feel that more subbass and a more lengthy decay would benefit the tuning a bit more to accommodate the more mid forward and bright tuning.

Midrange:
Simgot’s signature sound is a harman-like sound with some changes in the lower midrange, likely designed to even out the brightness of Harman IE. The Harman IE target is often considered a benchmark, but I find it can make vocals sound thin. This adjustment partially addresses many listeners’ complaints by alleviating the ‘thin’ vocals.
However, the brightness of the mid and upper treble continues to be a significant issue for people who prefer a more natural listening experience. While it surprisingly does not introduce any sibilance to ‘s’ and ‘t’ sounds in the voice, I would urge listening to this set before buying as it can be a potential deal breaker if you are particularly sensitive to raised mid and upper treble

Treble:
Here the EA1000 runs into some issues. The treble is very bright and can lead to some fatigue when listening to instruments such as electric guitar or hi hats. This is an absolute dealbreaker for me as it restricts my listening times, with the issue seemingly getting worse even if I lower the listening volume.

I have tried various nozzles and eartips provided in the box, however none alleviated the issue to an extent that is comfortable for me.

Technicalities:
The Simgot EA1000 offers a good soundstage for a DD driver with notable height and depth. The elevated treble region definitely gives a sense of elevated detail and accurate imaging. Instrumental separation and imaging is quite good for a single DD and sounds quite holographic. However, I did notice that the iem sounds almost echo-ey, which negatively impacted my experience with the bass slam and dynamics.

The timbre is completely off, I couldn't get any enjoyable sessions out of my piano playlist or any instrumentals. I suspect its due to the tuning.

The detail however is quite decent if you're into the type of iem that forces out detail with treble, its mostly non-sibilant which is another plus.

Conclusion:
For those who enjoy an exciting tuning that delivers forward, intoxicating female vocals and without sibilance alongside punchy tactile bass, the Simgot EA1000 would be a good fit at this price point. However, if you have issues with brightness and want a more full sound, I'd look elsewhere.

The Simgot EA1000 earphones exhibit a remarkable level of build quality that has stood the test of time. After five months of consistent use, they have shown no signs of wear or degradation. The earphones’ inner body boasts a glossy finish that remarkably resists scratches and marks, a notable distinction when compared to other high-gloss earphones like the Dunu Falcon Ultra and Tanchjim Origin, which have not fared as well over time.

At the $200 price point, the EA1000 offers an exceptional design that exudes premium quality. The use of sapphire glass for the faceplate is not only aesthetically pleasing but also instills confidence in its durability. This material choice is reminiscent of the ikko OH10s, which similarly employed sapphire glass to great effect, maintaining an unblemished appearance through prolonged use.

Beneath the faceplate lies intricate detailing that further accentuates the earphones’ luxurious feel. A large vent located on the lower body serves a dual purpose: it accommodates the passive radiator, contributing to an open sound and an expansive soundstage.

The two-pin connector system employed by the EA1000 ensures a secure and reliable connection, free from the common issues that can plague earphone usage. This robust connection system underscores the thoughtful engineering that has gone into every aspect of these earphones.

In conclusion, my experience with the Simgot EA1000 has been thoroughly positive. The build quality is solid and reliable, while the design strikes a perfect balance between elegance and functionality. These earphones are not just a listening device but a statement of premium elegance that stands out in both performance and appearance.


The Simgot EA1000 earphones are designed with long listening sessions in mind, providing sustained comfort without causing ear fatigue or discomfort. Although the stock tips initially presented a challenge with securing a stable fit, switching to alternative tips resolved this issue entirely. This adaptability is a testament to the earphones’ versatile design, accommodating a wide range of ear sizes and shapes.

With my relatively large ears, the EA1000 earphones nestle comfortably without issue. Their modest shell size suggests that they would be equally accommodating for most users, avoiding the bulkiness that can sometimes accompany larger earbud designs.

The angled nozzle of the earphones facilitates a deeper insertion into the ear canal, enhancing noise isolation. While the large vent prevents complete sound blockage, it strikes a balance by providing sufficient isolation to ensure an immersive listening experience without total disconnection from one’s surroundings.

In my extensive use, the fit and comfort of the Simgot EA1000 have been consistently reliable. It is my belief that these earphones will deliver a comfortable fit for most users, ensuring an enjoyable listening experience free from the common discomforts associated with prolonged earphone use.

Upon unboxing the Simgot EA1000, one is immediately struck by the quality of the stock cable included. This isn’t just any ordinary cable; it’s a 2-core silver-plated copper (OFC) cable, meticulously crafted in a litz structure. The litz configuration is renowned for its ability to reduce skin effect and proximity effect losses in conductors, which means it’s engineered to deliver a cleaner and more detailed sound.

The cable features a 0.78mm 2-pin connector, a standard in the industry, known for its reliability and ease of use. It terminates in a 3.5mm jack, the ubiquitous audio connector that ensures compatibility with a wide range of audio devices. The connectors themselves, along with the Y-split, are fashioned from a sturdy metal, which not only adds to the durability but also provides a touch of elegance to the overall design.

Now, while there’s much to admire, I do have a couple of quibbles. Firstly, the lack of modular terminations feels like a missed opportunity. In an ideal world, the ability to switch between balanced and unbalanced outputs would cater to the needs of audiophiles who demand versatility for their high-end gear. Secondly, while the cable is free from audible microphonics, a slightly softer cable could enhance the comfort for those marathon listening sessions. It’s not a deal-breaker, but something to consider for future iterations.

The preformed earhooks are a thoughtful addition, designed to conform to the natural contour of your ears. They maintain the cable’s position securely without causing any irritation, even after hours of use. The color coordination with the cable is a subtle yet appreciated detail, maintaining the aesthetic coherence of the product.

In terms of weight and thickness, the cable strikes a balance. It’s neither too heavy to cause fatigue nor too light to feel flimsy. This standard sizing ensures that the cable remains manageable and doesn’t detract from the listening experience.

Aesthetically, the cable’s white and silver theme is a visual treat, perfectly complementing the earphones’ design. It’s a testament to Simgot’s attention to detail, ensuring that the cable doesn’t just serve its functional purpose but also enhances the overall appeal of the earphones.


Drawing from my extensive experience with the Simgot EA1000 IEMs, I’ve come to a definitive conclusion regarding the ear tips provided out of the box. Frankly, the stock tips leave much to be desired, particularly for an IEM that commands a $200 price tag. The quality and performance of ear tips are not to be underestimated, as they play a crucial role in comfort, noise isolation, and even sound quality.

After experimenting with a plethora of tips, I’ve narrowed down my preferences to two distinct types: the Dunu candy tips and the velvet tips. Each brings its unique flavor to the auditory experience.

Velvet Tips: With the velvet tips, the bass response is immediately transformed. It gains a robust punch and dynamic range that breathes life into every track. The mid-range opens up, allowing vocals and instruments to occupy their own space with clarity and presence. As for the treble, it extends with a newfound crispness, adding sparkle to the highs without veering into sibilance.

Dunu Candy Tips: Switching to the Dunu candy tips, the bass maintains its vigor but with a more refined control, ensuring that it doesn’t overshadow the mids. The treble takes a step back, becoming smoother and more controlled, which can be a blessing for those sensitive to higher frequencies. The mid-range, however, is where these tips truly shine. It becomes fuller, more rounded, and natural, offering a sound that’s both engaging and true to the recording.

My advice to fellow audiophiles and enthusiasts is this: once you’ve acquired the Simgot EA1000, take the time to conduct your own tip-rolling experiment. The diversity of ear tips available on the market means that there’s a perfect match for everyone’s unique ear shape and sound preference. By finding the right pair, you’ll unlock the full potential of these IEMs, elevating your listening experience to new heights.

The EA1000 will thrive with such sources, providing a sound that’s both rich and balanced, without any unwanted sharpness.

For those who prefer bright, analytical sources, be mindful that these can accentuate the treble in the EA1000, potentially leading to a sound that’s too energetic in the higher frequencies. It’s a matter of personal preference, but it’s worth noting for those sensitive to treble.

The EA1000’s sensitivity to the source is quite pronounced. A well-paired source can make a significant difference, turning a good listening experience into a great one. With a compatible player, the EA1000 can deliver an outstanding level of sound quality that elevates your music to new heights.

With its 16 Ohms impedance and 127 dB/Vrms sensitivity, the EA1000 doesn’t require a powerful amplifier to perform well. This means you can enjoy its full potential with a variety of devices, from portable DAPs to smartphones. However, the source’s quality is crucial. A high-quality source with a low noise floor and clean output will ensure that the EA1000 performs optimally, delivering a clear and detailed sound.

In essence, the Simgot EA1000 is a versatile IEM that, when paired with the right source, can provide a delightful listening experience. It’s worth taking the time to find the right match to ensure you get the most out of these earphones’ capabilities.


Interchangeable Nozzles:
Drawing from extensive experience with the Simgot EA1000 IEMs, it’s clear that the interchangeable nozzle system is a standout feature, offering a level of customization that caters to the discerning audiophile. Here’s a detailed exploration of how each nozzle influences the sonic landscape:


•Default Metal Nozzle (RED Ring): The red ring nozzle is the starting point for many, providing a balanced staging that doesn’t favor any particular frequency range. The mids, with a very slight thinness, allow for a crisp vocal presence and a clean separation of instruments. The bass response is commendable, striking a balance between punchiness and precision. It delivers good detail and depth, making it versatile across various genres, from classical to pop.

•Black Ring Metal Nozzle: Opting for the black ring nozzle introduces a more distant staging, akin to sitting a few rows back in a concert hall. This shift in soundstage can be quite immersive, giving each instrument room to breathe. The mids take on a leaner character, which may appeal to those who enjoy a more analytical listening experience. The treble’s slight prominence brings forward the finer details in high hats and cymbals, offering a sparkling clarity that’s particularly noticeable in high-resolution tracks.

•Bronze Nozzle: The bronze nozzle is a revelation for those seeking a warmer, more intimate sound. The staging becomes closer, enveloping the listener in a cocoon of sound. The midrange gains significant texture and body, enriching the overall musicality and bringing a lushness to vocals and stringed instruments. The bass response with this nozzle is deeper and more articulate, providing a substantial foundation that doesn’t encroach on the mids. The treble is restrained just enough to maintain detail without inducing fatigue, making it ideal for long listening sessions.

After thorough testing with all three nozzles, the preference for the bronze nozzle resonates with a pursuit of a rich, engaging, and cohesive sound signature. It’s the nozzle that seems to best complement a wide array of musical preferences, offering a sound that is both immersive and true to the recording.

In essence, the Simgot EA1000’s nozzle system is not just about subtle changes; it’s about tailoring the listening experience to personal taste. Whether it’s the neutral starting point of the red ring, the spaciousness of the black ring, or the intimacy of the bronze ring, each nozzle serves as a key to unlock different facets of one’s music collection. The bronze nozzle, in particular, stands out as the go-to choice for a rich and detailed audio journey.



Tonality:
The Simgot EA1000 IEMs offer a nuanced and versatile tonality, suitable for various listening preferences, thanks to their advanced driver technology and replaceable tuning nozzles.The tonality of the EA1000 leans towards a slightly V-shaped signature with some emphasis on the treble region. This results in a sound profile that is clear, bright, and "fresh," with a notable amount of bass presence. The bass is characterized by its mid-bass focus, providing texture and physicality, though it lacks the deep sub-bass rumble that some might seek. This creates a realistic and bodied feel to snare hits and percussions without overwhelming the overall sound

The Simgot EA1000, particularly when paired with the brass nozzle, offers an exceptional bass experience that is both enjoyable and technically proficient. Here’s a detailed breakdown of its bass performance:

The precise imaging capability of the EA1000 allows for an engaging experience, as it mimics the sensation of being in the presence of the musicians. The ‘blacker’ background of the soundstage, which refers to the profound silence around the notes, serves to enhance the contrast and make the music stand out more vividly.

Instrument separation and layering are executed with excellence, ensuring that each instrument is given its own space, thus avoiding congestion even in complex musical passages. This separation is essential for accurately reproducing the nuances of live performances.

The dynamic range of the EA1000 is also commendable. It adeptly handles both subtle details and intense sections of music, enhancing the realism of the soundstage and making quiet sounds seem quieter and loud sounds louder, akin to a live setting.

In summary, the Simgot EA1000 offers an exceptional soundstage and imaging performance, providing an immersive and realistic listening experience. The expansive soundstage, precise imaging, and excellent instrument separation all contribute to a technically impressive and musically satisfying performance. These qualities indeed make the EA1000 a top choice for audiophiles who value a spacious and accurate soundstage in their IEMs.


Detail-Oriented Listeners: If you’re someone who appreciates the finer details in music, the EA1000’s high-tech driver and brilliant technical abilities make it an easy recommendation. It’s designed to deliver stunning resolution and detail, making it perfect for those who want to hear every nuance of their favorite tracks.

Build Quality Appreciators: The EA1000 boasts phenomenal build quality with a metal construction and a decorative glass faceplate, appealing to users who value the durability and aesthetics of their audio gear.

Sound Customization Fans: With three pairs of replaceable nozzles offering different acoustic properties, the EA1000 is ideal for listeners who like to fine-tune their sound experience. These nozzles function as different tunings, allowing you to adjust the IEMs to fit your personal preferences.

Efficiency Seekers: For those who don’t want to invest in a powerful amplifier, the EA1000’s 16 Ohms impedance and 127 dB/Vrms sensitivity mean it can be driven by most sources, including portable DAPs and smartphones.

Comfort and Fit Connoisseurs: The all-metal housing and design of the EA1000 not only provide a premium look but also contribute to comfort, making these IEMs suitable for long listening sessions.

Bass Lovers: If you enjoy a physical, dense bass response, the EA1000 is known for its ability to deliver deep and impactful lows without compromising the clarity of mids and highs.

However, if you are sensitive to sparkling and slightly spicy highs, you might want to consider this before purchasing, as the EA1000 can emphasize treble depending on the source.

In summary, the Simgot EA1000 is a compelling choice for anyone looking for a high-performance IEM with great build quality, customizable sound, and efficient power handling. It’s a flagship-level performer that offers a lot for its price point.

Disclaimer:​

Good morning, Readers! Today we will go over the Simgot EA1000 Fermat. I eventually made it to the top after starting with the EM6L, EW200, and EA500LM.


Even though it’s not exactly a single driver, I feel like comparing it to other similar IEMs. Simgot wanted to add a passive radiator to the EA1000 in order to achieve the desired result, but because it is passive, it cannot be considered a driver.


If you are sensitive to sparkling and slightly spicy highs, these are not for you, just like the EW200 and EA500LM.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music. I fall into the audio enthusiast category.


So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:​

• Driver: Second generation DMDC 10mm dual-magnet & dual-cavity dynamic driver + 6mm PR
• Diaphragm: Purple-gold dome diaphragm
• Impedance: 16Ω±15%(@1kHz)
• Sensitivity: 127dB/Vrms Frequency response range: 10Hz–50kHz
• Effective frequency response: 20 Hz–20 kHz
• Connector: 0.78mm 2-pin
• Cable material: high-purity silver-Plated OFC Litz Structure
• Price: 260 USD more or less

Packaging:​

The packaging of the Simgot EA1000 Fermat represents a clear improvement, and considering its price, it seems correct that it stands out for class. Aesthetically less mystical but with a tribute to the mathematician named Pierre de Fermat, I don’t think there is a particular correlation; simply, the result obtained by the EA1000 is the result of precise calculations.

Accessorie boxes
Once the package is opened, we find the tribute to Fermat, and underneath the IEMs are the following accessories:

• Hard case
• Nozzle with base
• Nozzle o-rings
• 6 pairs of tips
• Litz cable
• Manual and QC

Obviously, the packaging is richer and reflects the price at which the product is positioned quite well. The hard case is finally not anonymous but has the Simgot logo above and a phrase below. The tips are the standard 07; I am not sure why they included two identical sets, but the cable is noticeably better than the one used on previous models. The nozzles arrive on an aluminum base rather than in a plastic bag, and I noticed a small error in the writing engraved on the base, which reads “Salu” rather than “Salute”. I could not tell whether it was a problem with the machine or an error in the file. I do not think it is anything serious, but I would prefer not to see control issues on a similar product.

Design/Build Quality:​

The Simgot EA1000 Fermat is the closest thing to a jewel; the aesthetics, and especially the materials and color choices, evoke jewelry. This choice may not appeal to everyone, but I do not see any issues, and I do not believe I am losing masculinity by wearing the Simgot EA1000.


In terms of shapes, we are more or less the same as those seen with the EA500LM, quite natural shapes that shouldn’t cause problems of any kind. In the internal opening, we have 3 ventilation holes, one of which is really large. On the outside, the faces appear to be made of glass, which is aesthetically very elegant with a rose gold or copper-colored edge. What I can notice is that the shells are not exactly very light; I think they are obtained from a metal fusion and then CNC machining.


The Kefine Delci, on the other hand, have a machined aluminum shell and are much lighter, undoubtedly with a higher quality shell. I hope to see a Simgot with a similar shell in the future. As for the ventilation holes, I can venture that the small ones are for the DD while the larger one is for the passive radiator, assuming that it is truly an opening and not just something aesthetic.

Initial sound impression:​

What I noticed as soon as I put on the Simgot EA1000 was the tuning, which corresponds exactly to what I expected, but what is surprising is the timbre, which has a devastating naturalness. I don’t know if there are IEMs with a more correct tone but this really seems to me very close to what something natural should be. The driver, despite the same technology as the EA500LM, has a totally different material dome, which should be more rigid. I can tell you that it has a very high resolution and the transitions are lightning fast.



Harman tuning follows and using the nozzles, you can try more variations even if a couple are very similar to each other. The mids, on the other hand, could be a bit shouty at times, but fortunately, 98% of the time, this is kept under control. The medium is vivid and detailed with a very high resolution. What is surprising is the timbre of the voices, which is extremely pleasant and natural (they also have the right thickness). Then there is the instrumental part, where guitars and cymbals are extremely real thanks to the vibrations that have. The treble could be high for those sensitive to high frequencies, but the reality is that they are extremely crisp and smooth and make their representation rich in macro- and micro-details with a large presence of air; they have that touch of crystalline and transparent.

Tips Rolling?​

Tips Rolling

Depending on what nozzle and source are used, you may want to slightly adjust the sound with different tips. It is needless to say that the BGVP 07 tips are excellent but you can certainly try models with higher quality too.


I currently tried the TRI Clarion, which has excellent comfort but made me slightly lose something in the low range.


The Kbear SS20, on the other hand, has an excellent balance between Stage and the other frequencies, but it appears that I have lost something in the bass. In this case, I switched to the gold-colored nozzle, and everything seems to be great again.


I decided to try the KZ Starlines, and to my surprise, they provide incredible comfort while slightly reducing the sharpness of the high frequencies, giving the body a lower range. Surprisingly, they appear to be very good, but I seem to have lost some definition.


Honestly, using tips like Starline on a similar product doesn’t make sense so I continued with the tests.


I thought the Dunu S&S were not comfortable on this model; I had to change my mind but I think they give a bit of a concert hall effect. I don’t particularly like them.


The Divinus Velvet, on the other hand, has excellent comfort but I usually use it where I need to reduce the pressure in the ear canal and in the case of the Simgot EA1000, there are no important pressures to eliminate. Reduces low frequencies a bit.


The BGVP 08, on the other hand, surprisingly resembles the KZ starlines; the shape varies very little but what they have in common most is the structure that surrounds the nozzle. I have come to the conclusion that, compared to wide bore tips, narrow bore tips are slightly more suitable. However, you sacrifice a bit of soundstage so as a final balance, the SS20 tips are the ones I decided to use for the review.

Comfort & Fit:​

For comfort, I feel like recycling the same thing I wrote for the EA500LM:


“As far as comfort is concerned, the shell has the right shape. The only sore point could be their weight; if, by chance, you have a particular shape of the ear, it could create pressure points. Usually, with the right tips, you can solve these problems.”


Fit with SS20

Nozzle:​

Gold White:

On the EA500LM, I was certain that this was the best nozzle; on the EA1000, the question is slightly different. As you can see from the photos, the silver nozzle with the red o-ring appears to be the most free of them all. The gold one has a fabric filter with a hole in the middle. I believe it affects both treble and bass, while also slightly smoothing up midrange perception. My main concern is that limiting the freedom of sound output so drastically will compress the stage slightly. I was wrong because, in reality, after thinking about it, this is the nozzle, which has a central part completely free of filters. The sound has a greater sense of harmony and balance, as well as being more holographic.

Silver Red:

It suppresses the holographic image a bit, but in reality, the nozzles are also made of different materials; the gold one is like brass, which could also oxidize, while the other does not. In my opinion, the material also has little influence. The positioning of the various sounds with the gold nozzle seems much more precise to me.

Silver black:

I wonder if this nozzle really makes sense, as I feel very little difference from the silver red. Despite the presence of the foam, there are very few changes to the trebles, which are slightly more docile (they would need a higher density) and the sub-bass, which seems slightly fuller.

I didn’t notice any differences after burning it for a few hours. They sound great right out of the box.


As previously said, I continued the review with the Kbear SS20 tips. Certainly, the driver, although similar to that of the EA500LM, has a totally different dome. In addition to that, there is the configuration of the single driver combined with the passive driver. Reading among the specifications, the larger ventilation hole corresponds to the passive driver, and the internal driver has a closed cavity that communicates with this passive driver, which has an external vent.


In fact, this “driver,” which is more of a membrane, resonates alongside the main driver, aiding in frequency response, particularly in the low range. It is difficult to demonstrate how and if it has an impact, so I will refrain from going into detail and relying on assumptions. What I can say is that the bass reverb has a distinct definition that I did not experience on the Letshuoers DZ4.


Simgot’s sound timbre is undeniably distinctive. In fact, I could describe them exactly like the EA500LM, though the driver is far more refined in his presentation of every detail.


The tonality in the midrange is slightly more coherent than that of the EA500LM, and I do not notice the slightly cold touch to the voices. The highs, on the other hand, are much more detailed, but they also have a lot of separation and airiness.

Bass​

In terms of bass, we are absolutely not at basshead level but the quality is extremely good. There is a clean bass and a slight emphasis on the sub-bass without deviating from the naturalness of the tuning. The bass is precise, fast, and rich in texture, just the way I like it. Compared to the EA500LM, the quantity seems very similar to me but the quality is slightly different, probably the rumble has more thickness due to the passive radiato. It seems to have more control.


No track will emphasize bass or sub-bass rumble beyond the “natural” threshold.

Mids​

It’s been a while since I heard such interesting mids; even though they should be recessed, I hear them at the forefront with the other frequencies. A lot of upper-midrange energy might be a little warm for some of you but I assure you that if you have no problems, you will be rewarded with super silky and luxurious female voices. On the lean, you could have used a touch of extra warmth but honestly, you just need to have the headphones with something similar to the Hidizs S9 Pro Plus.


As far as musical instruments are concerned, extension and separation help the instruments maintain their naturalness. The male voices are slightly less pleasant and are also less forward than the female ones. It could simply be because of my preferences!

Treble​

With airy and open high frequencies, the amount of detail that overwhelms you, leads you to believe that there are other drivers at work, but the reality is that the tuning and driver have worked wonders. Air and sparkles can be appreciated track by track, but if you are particularly sensitive, they may bother you. Despite this, compared to the EA500LM, I noticed fewer tracks that were too hot or harsh. A treble extension that does not make me miss anything from the songs.


Because it is brighter than other IEMs, it is obviously more difficult to achieve high sound pressures (the Hidizs MP145 are more tolerable at high volume), but if you plan to push, you should consider switching to foam tips.

Soundstage and Imaging:​

In my opinion, the Simgot EA1000 soundstage is superior to the EA500LM (not exaggerated but there is a certain concert hall effect in certain tracks), but what makes the biggest difference is the precision of the image, in which each sound seems to have a fixed and precise track that reaches your eardrum without crossing any other sound. You will notice that each instrument and the voices are totally separate. The layering is also excellent.

Comparison:​

The price of the Simgot EA1000 Fermat becomes spicy, we are no longer in the territory considered economical but more in a medium/high price based on who is reading the review. If we consider the prices of audio products, it is not an astronomical sum. In this price range, planar drivers also come into play.


vs Simgot EA500LM


Simgot EA500LM

Some people prefer the Simgot EA500LM over the Simgot EA1000, so who am I to tell you which one to buy? Yes, I am nobody! As far as I’m concerned, the resolution is on another level, the difference is certainly more marked than the EW200 and the EA500LM. There is a difference but the tuning and sound signature are the same so unless you are so attentive to detail, you can easily stop at these. Furthermore, if you don’t have both, you can’t say which one is better. Are you ready to shell out 400 USD?


vs Hidizs MP145


Hidizs Mp145

The Hidizs MP145 were a huge success, and I do not believe there has ever been a more popular planar IEM. In terms of detail and high frequency extension, the EA1000 outperforms them. The Hidizs MP145 have decidedly warmer tuning and a much more present bass; they can be pushed to higher volumes without issue, and you will not be flooded with too spicy highs. The soundstage, on the other hand, is one of the largest ever, and the planars excel in this area. Both are constructed with high quality materials. It is undoubtedly more appealing to the majority of people. The shell is very large and is not comfortable for everyone.

Conclusion:​

Simgot EA1000 + SS20

I have no doubts that the Simgot EA1000 Fermat are excellent IEMs. I am aware that these are IEMs that a newcomer to the hobby would be unlikely to purchase, but I am confident that many in the audio industry will appreciate them. The target users are those who enjoy high fidelity; recording must be as close to reproduction as possible, and in this case, I believe there is nothing to improve, at least in terms of sound quality.


In terms of personal preferences, I would have preferred more bass presence. However, the Simgot tuners know what they are doing in terms of sound, and an audio enthusiast like me has no right to criticize their work. In addition to the sound, they got the aesthetics right; it is very elegant and solid, and the accessories are adequate, but I would use two different types of tips in future.


If the brilliance does not knock you out, you will be rewarded with an IEM that takes you through track after track, providing details, sparkles, and resolution of a completely different kind.

General Information​

At the time of writing, the EA1000, codename “Fermat”, is the second highest IEM in the entire product line of Simgot. It shares quite a few technologies with the flagship EA2000 (“Boson”), namely the “DMDC” dual magnet dual-cavity dynamic driver design and the 1DD+1PR driver topology. EA1000 also features a brand new “Purple-Gold” diaphragm that aims to simultaneously achieve high rigidity, lightweight, and elasticity, the desirable characteristics of a diaphragm in DD.



First, let’s talk about the DD. As you know, DD makes sound by moving a diaphragm back and forth according to incoming electrical signal, translating it into soundwaves. This movement is possible thanks to a coil of conducting wires (“voice coil”) glued to the diaphragm and wrapping around a permanent magnet. When the electrical current flows through the coil, the coil acts like a magnet and moves backward or forward depending on the direction of the current, bringing the diaphragm along with it. Ideally, we want to the diaphragm to move back and forth quickly (to produce high frequencies) over a long distance, return to the middle position immediately when the signal stops, and do not lose shape (distort) when doing these acrobatics. In order to achieve these requirements, manufacturers need to simultaneously reduce the weight and increase the hardness of the diaphragm, reducing the weight of the voice coil, and increasing the strength of the magnet. The DMDC driver design of Simgot handles the the magnet strength. The “purple-gold” coating developed by Simgot provides the lightness and strength to the diaphragm. Taken together, we have a nice DD sitting at the heart of EA1000, powering the listening experience.

However, the resulting sound quality of a DD-based IEM relies on more than just the driver. It is these factors, that make the EA1000 shine, in my opinion.



To me, the star of EA1000’s technology is the 1DD+1PR driver topology inherited from the Boson. PR here means “Passive Radiator,” a 6mm diaphragm that vibrates thanks to the air pressure from the main 10mm DD rather an electrical voice coil.

How does that work? If you look at a DD, you would likely find two openings, one at the front of the diaphragm for the sound to escape and one at the back of the diaphragm to balance or release the pressure. When you glue the DD into an IEM shell, the back opening of the DD would connect to a “cavity” or a “chamber” that are usually built into the shell. When the diaphragm vibrates, it would compress and release the air volume in the chamber. Usually, we would poke a hole in the chamber (a.k.a., “back vent”) to release the pressure deliberately to control the behaviour of the DD.

Now, imagine we attach a diaphragm on the vent instead. Ideally, the passive diaphragm would move in unison (but in an opposite direction) to the diaphragm of the main DD. All that remains is designing the chamber carefully to control its resonance, thus changing the frequency response of the passive diaphragm. In other words, it would make the same sound as the main DD but its sound would come from outside the ear canal, leading to some interesting sonic experiences.

Non-sound Aspects​

Packaging and accessories: The art design and packaging of EA1000 feel classy, elegant, and deliberate. Regarding accessories, Simgot provides EA1000 with most items that you might need: two types of silicone ear tips, an IEM cable, a carrying case, and two sets of interchangeable nozzles. The case is smaller than usual but still fits the IEM well and has enough space to carry the nozzle sets and some ear tips. The cable is a bit stiff but manageable. Unfortunately, only 3.5mm option is available.





Earpieces design: The earpieces of EA1000 are constructed from stainless steel and polished to a mirror finished. Faceplates are glasses, which do raise some concern about their fragility. Still, the earpieces and faceplates remain relatively pristine, with only some hairline scratches after weeks of usage.







Regarding the size , the earpieces of EA1000 are smaller than average, especially if you compare them to the increasingly prevalent multi-driver IEMs. The nozzles are also on the smaller side. I found that I needed to do more “tip rolling” than expected to achieve a reliable and comfortable fit. After finding the right tips, I found EA1000 to be a comfortable IEM in long listening sessions. Noise isolation is not a strength of this IEM, likely due to the vents, passive radiators, and the cavity inside the earpieces.

Ear tips recommendation: I found that I can have two different sonic presentation with EA1000 just by changing ear tips. If I use a larger or longer tips (e.g., Spinfit CP145 or W1), I can push the earpieces away from the ear drums and thus increase the perceived width of the soundstage. However, the uncanny “out of the head” soundstage effect that EA1000 can do is diminished.

Alternatively, I can use shorter and smaller tips to wear the IEM deeper, pushing the passive radiator right against the concha of my ears. In this case, the soundstage feels narrower and the instruments concentrates more at the phantom center of the stage inside my hear. However, the uncanny “out of the head” effect of some background elements in the soundstage becomes stronger.

I personally use Azla Xelastec ear tips with EA1000, aiming for a balance between two of the described presentations.

Timbre, tonality, and tonal balance: Figure shows the frequency response of EA1000 against the Harman in-ear target. Measurements were done with an IEC-711-compliant coupler and might only be compared with other measurements from this same coupler. Above 8kHz, the measurement might not be correct. Visit my graph database for more comparisons.



It is helpful to think of an IEM as a filter that highlights or subdues different parts of the incoming audio signal. This effect can be measured objectively by the squiggly lines above, called Frequency Response (FR) graphs, which measure how loud an IEM is at different frequencies from 20Hz (bass) to 20kHz (upper treble). Subjectivity is how your ears and brain interpret the effect of that filter on your music and decide whether it is “enjoyable.” There are some “rules of thumb” when it comes to tonality, but most interesting IEMs usually bend the rules masterfully.

If you have listened to any IEM from Simgot, the tonality of EA1000 would be quite familiar: clear, bright and “fresh” tonality paired with a decent amount of bass. You can choose between 3 sound signatures by swapping the nozzles of EA1000. The stock nozzles (stainless steel with red O-rings) is the least dampened as it does not have any foam or filter inside to absorb any frequencies (to my ears, zero dampening is ideal). Putting these nozzles on EA1000 nets you a tonality is that inspired by the Harman IE2019 target, with only two deviations: more lower-midrange and midbass (good!) and less subbass (meh). Thanks to the lower-midrange deviation to balance against the “true Harman” upper midrange, EA1000 has a natural reproduction of everything in my library, from vocals to piano to violin solo to large orchestral pieces.



At the same time, it does not dull down the clarity that you would expected from a “Harman-ish” IEM, which can be quite intense if you are used to warmer IEMs. For instance, Ed Sheeran’s “shivers” in the = album is too much for me. It was not sibilance (i.e., treble peak at 6kHz or 8kHz) that was problematic. No, EA1000 is not a sibilant IEM. It is the shrill and strident in his voice when hitting high notes that got me. It should be noted that this track is the “worst case scenario.” Case and point, the next track in the same album, “First Times”, sounds quite pleasant.



Switching to the golden nozzles which implements “Simgot-Golden 2023” target, I found the the tonality becomes much more imbalance toward the upper midrange. The tonal balance reminds me of an Etymotic IEM. After the novelty dissipated, I found that these nozzles are just not for me. Switching to last nozzles (stainless steel with black O-rings) which implements “Simgot Classic” target, I found a different, yet also bright sound signature. Implementation-wise, these nozzles seem to be the most dampened as they are filled with acoustic foams. Yet, I hear more sibilance across my library with these nozzles. Therefore, I would say whilst the tuning nozzles of EA1000 technically work, they are not practically useful because they let you increase rather than decrease the brightness of the tuning.





Still, besides the fringe cases such as Ed Sheeran’s Shivers, EA1000’s tonality and timbre is quite natural and enjoyable to listen, putting in the “great” (4/5) bracket in my book.



Bass and perceived dynamic:

The strength of the bass of EA1000 lies in the sense of texture. Simply put, bass guitars, cellos, and contrabasses sound very nice. For instance, when I listen to “Playing God” by Polyphia, my attention kept getting pulled toward the bass guitar. I also kept going to back to cello recordings in my library, such as the album Score by 2CELLOS, due to how EA1000 renders the sound of the lower strings of cellos. Instead of a smoothened low-pitch “ummmm” sound, these stringed instruments sounds like “Brrrmm.” Grippy.

The main weakness of EA1000 is that it does not sound as dynamic as I expected. It means the rapid jumps of loudness in the music, such as the first bass drop in “Playing God”, lack a bit of exaggeration and energy to make it “slam.” Perhaps this lack of dynamic is a function of the brighter tuning of EA1000. Whilst it is not a dealbreaker, in the sense that it does not make EA1000 sound boring, it’s something that I wish EA1000 can do better.

In general, I consider bass and dynamic of EA1000 as “great” (4/5) thanks to the texture of the bass.

Resolution: To me, “resolution” can be broken down into three components: (1) Sharpness, incisiveness, or “definition” of note attacks (see the figure above). (2) The separation of instruments and vocals, especially when they overlap on the soundstage. (3) The texture and details in the decay side of the notes. The first two give music clarity and make it easy to track individual elements of a mix. The last provides music details and nuances.



Thanks to the tuning, EA1000 is a clear sounding IEM. The DD itself is also quite good, maintaining a good level of note definition and instrument separation across the frequency response. For instance, the IEM can cope with busy soundtracks in the Ghost of Tsushima quite competently, maintaining enough separation and definition to avoid a mushy and congested sensation. Though, as expected, when I compare EA1000 in direct AB tests against some good multi-driver IEMs, EA1000 does fall behind.

Still, I find the resolution of EA1000 to be firmly in the “good” (3/5) level in my book, trading blows with the likes of Moondrop Blessing 2.



Stereo imaging and soundstage: Stereo imaging or “soundstage” is a psychoacoustic illusion that different recording elements appear at various locations inside and around your head. Your brain creates based on the cues in the recording, which are enhanced or diminushed by your IEMs, your DAC, and your amplifier. In rare cases, with some specific songs, some IEMs can trick you into thinking that the sound comes from the environment (a.k.a., “holographic”)



Soundstage and stereo imaging are perhaps the strongest aspect of EA1000 performance.

No, this IEM is not going to sound like your open back headphones or your stereo speakers. In fact, the overall shape of the stage is rather than unremarkable. Like most Harman-inspired IEM, the soundstage of EA1000 is quite concentrated in the phantom center inside the head, leading to the perception of a shallow but wide soundstage. On these aspects, the stage of EA1000 is just average.

However, the background elements of the stage is where it gets interesting. With spacious recordings, either orchestral or electronic, EA1000 can create an uncanny illusion that some background elements come from the outside of the “stage” within the head. This effect is clearer when instruments are panned to the sides of the stage. Yes, this effect is not something immediately highlighted and does not make the overall perception of the soundstage larger. But, for me, it gives an interesting new effect to the old tracks. I found myself going through my library to find more tracks where this effect is more audible. For a self-proclaimed soundstage addict, I see this as an absolute win. (4/5)



Multimedia usage:

EA1000 works quite well for FPS gaming. I hear a nearly spherical stage, making it easy to gauge the direction and distance of gunshot and footsteps, even though EA1000 does not offer laser sharp, pin point precision. Atmospheric games and movies work well with EA1000 as expected.

Pairing​

EA1000 is an easy to drive IEM. It sounds good directly from the Apple USB-C to 3.5mm adapter (a.k.a., “Apple Dongle”) and only gets better from there. My only complain with the apple dongle pairing is that the low-end of EA1000 sounds a bit weaker and less defined. Moving to W4, the immediate change was the base: more prominent in the mix with stronger impact and sense of texture. Moving to DX300 presents another step up. The bass is even more prominent and the stage feels deeper, meaning the further sounds in the mix are pushed further away.



I also tested EA1000 with Simgot own dongle, the DEW4X. The result, for me, was mixed. On the plus side, the warmer-than-neutral tuning of DEW4X works nicely with EA1000, making its midrange more pleasant and the low-end more prominent. On the other hand, the stage is noticeably narrower and the nice “uncanny” effect that I describe was not apparent when I use the 3.5mm output of DEW4X. Switching to 4.4mm output brings the soundstage in line with other dongles, but the DEW4X is quite loud even at the first few volume levels. Yes, there are solutions, so this loudness is an annoyance rather than a dealbreaker. I can recommend DEW4X with EA1000, only if you also swap the stock cable for a 4.4mm one.

Comparisons​

Moondrop Blessing 2: This legendary IEM has been serving as my benchmark for a “good” IEM in terms of resolution since the early days. I put this comparison here just to capture my surprise of how much these two IEMs resemble each other in both tonal balance and resolution. From this perspective, the technical performance of the DD inside EA1000 is quite impressive.



Dunu Falcon Ultra (Blue Nozzle, S&S ear tips): Perhaps no review of single DD IEM is complete without a comparison with the Falcon Ultra, one of the most accomplished single DD IEM in the late 2023 and early 2024 season. In this test, I use the default configuration of Falcon Ultra (blue nozzles) where it sounds the most detailed and clear. Listening to EA1000 and Falcon Ultra highlights the convergence towards homogeneity of the IEM market. Not only the tonal balance of these IEMs sound incredibly similar, they have nearly identical loudness at the same volume level. I would say the EA1000 is slightly ahead of the Falcon Ultra on all technical aspects: it’s slightly more resolving in busy recording, has slightly more dynamic bass and slightly better bass texture. The uncanny soundstage effect of EA1000 is a bonus, but I find the Falcon Ultra to have a larger soundstage.



HiBy x FAudio Project ACE (Comply foam tips): Finally, we have something that sounds different. In case you haven’t heard about this IEM, Project ACE is a $250 single DD IEM collaboratively developed by HiBy and FAudio, a Hong Kong audio boutique famous for DD-based IEMs. The first impression when I swap from EA1000 to Project ACE was shock due to the difference between tuning. The treble emphasis at around 6kHz and the subdued upper midrange of Project ACE stood in stark contrast against the suddued treble and boosted upper midrange of EA1000. I don’t think any approach is superior to the other, as my brain can EQ both sound signatures without much difficulty. After the “brain burn-in” / EQ kicked in, I found that the tuning of ACE makes the soundstage feels more spread out, not crowding the phantom centre like EA1000. However, EA1000 regains ground thanks to, again, the uncanny out-of-head illusion of the background elements of the music. The instrument separation, note definition, and micro details at the decay end of the note are all slightly better on Project ACE. Even though ACE does not have a distinct bass shelf, its tuning approach to take advantage of the equal loudness curve makes it sounds more dynamic. On ther other hand, EA1000 has a slight edge in terms of the bass texture.

Conclusions​

I must admit I come into this review with very high expectation due to the reputation that preceeds EA1000. I’m glad go say that I was not disappointed. EA1000 is an accomplished DD-based IEM with a “special sauce”: the uncanny out-of-head imaging with many recordings, possibly thanks to the passive radiator. Beyond the sonic performance, EA1000 also scores high in terms of the accessories and overall packaging. In overall, it’s an impressive “mid-fi” IEM.

Should you get EA1000? As usual, it depends. You need to answer to yourself: how much do you like/dislike the tonal balance of Harman IE2019 target and the IEMs that are tuned closed to it? If that sound signature is your favourite or at least does make most of your music library sounds fatiguing and shrill, then EA1000 is a good option to consider. I also see this IEM as a perfect spot to pause on the gear upgrade “climbing.” Give it a good dongle, find the most suitable ear tips, change to a nice looking 4.4mm cable, and you perhaps you can stop thinking about upgrading gears for a while.

What I like about this IEM:

• Uncanny, out-of-head stereo imaging with the right tracks
• Bass texture
• Good instrument definition and separation
• Great design, build quality, packaging

What could be improved:

• Small shell and short nozzle can create fit challenges
• Harman-ish tonality can sound shrill and strident with some vocal
• Tuning nozzles work but are not useful

Absolute Sonic Quality Rating: 4/5 - Great

Bias Score: 4/5 - I like this IEM!

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.

Sound Impressions:

Sound impressions below is done using the Silver/Red nozzle with Pentaconn Coreir & stock eartips.

Click to expand...

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.

If you're a fan of the EA500 LM and looking for an upgrade, the EA1000 is a clear step up, offering a discernible upgrade in every aspect.

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.

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…

All tracks mentioned are clickable links that allow you to open the reference track in the streaming service of your choice (YouTube, Tidal, Qobuz, Spotify, etc.)

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.

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 review sample was kindly provided free of charge.

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:

https://www.linsoul.com/products/simgot-ea1000-fermat














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.



Specifications

• Driver Type: 2nd generation DMDC™ dynamic 10mm dual-magnet, dual-cavity, 2nd generation DMDC™ driver. 6mm passive radiator.
• Diaphragm: Sputter deposition purple gold diaphragm.
• Sensitivity: 127dB/Vrms(@ 1kHz).
• Impedance: 16Ω±15%(@ 1kHz).
• Capsule Connection Type: 2 Pin 0.78mm.
• Frequency Response: 10Hz-50kHz.
• Effective Frequency Response: 20Hz-20kHz.
• Cable: High purity silver plated OFC cable in Litz structure.
• Jack Connector: SE 3.5mm.

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.
