SIMGOT EA2000

Introduction:​

This time, I have the pleasure of reviewing the Simgot EA2000, Simgot’s flagship IEM with a 12mm dynamic driver and a 6mm passive bass radiator. The unique shell design is easily identified by the round opening in the inside of the shell, outside of the nozzle, and facing the ear. This “external” driver configuration immediately reminded me of other manufacturer’s use of bass drivers in the similar location. While others use an active driver to transmit sound through bone conduction, Simgot takes a “passive” approach with a passive radiator, usually found in speaker applications to get extra power out of smaller enclosures. In short, the internal dynamic driver is connected to the passive radiator by an air chamber giving the IEM more “surface area” to produce the bass frequencies.

Another technically interesting feature of EA2000 are the swappable plug ends. Simgot decided to add circuitry to the plug end to provide different tunings for the IEM instead of having switches/plugs on the IEM side. Seems interesting. Let’s check out the EA2000!

The Package:​

The EA2000 comes in a nice, not too big, black and copper color “Boson” themed presentation box, and a good set of accessories. In most cases, I usually just take out the IEM and I’m done with the box. For EA2000, I don’t have much to say other than the package is nice, secure, and includes a good set of accessories. I will say that I do like the included IEM case. The magnetic closure flap top has a holder for the tuning plugs. The case easily stores EA2000 with stock cables with room for perhaps larger cables if needed. Measuring 3.5in(W) x 2.75in(D) x 1.5in(H) (90 mm x 70 mm x 38 mm) it’s a nice size for daily carry in a backpack or a smaller messenger bag.

Box:​

Contents:​

• Magnetic IEM case
• 8-core SPC MMCX cable with swappable terminations (two 3.5mm and 4.4mm)
• 6 pairs of ear tips (S/M/L)

At the time of this post, the price for Simgot EA2000 on Amazon US store is $266.31.

Tuning Selections:​

One of the unique features of EA2000 is the swappable tuning plugs. As shown in the picture, the package comes with three plugs:

• 3.5mm, single-ended, C3A035 “C”, the blue plug
• 3.5mm, single-ended, N3A000 “N”, the black plug
• 4.4mm, balanced, N4A000 “N”

The plug barrel can be unscrewed to release the plug from the cable-side connector. They are aligned by a “dot” marker that is easily seen and it will only engage in one direction, thus avoiding any chance of misconnection. The “dots” don’t perfectly align which triggers my OCD but it is close enough. I personally found the swappable plugs very convenient because I can keep the IEM in my ears while I change the plug. Keeping the IEM in the same position in my ears makes the comparison easier compared to changing switches/plugs in the IEM side. Nice idea!

From my listening, the two plug types “C” and “N” offer two flavors. The N3A000 “N” plug (both 3.5 and 4.4) offers a balanced tuning with a slightly longer decay characteristics that makes the soundstage very wide and deep. The “N” plug makes listening to soundtracks, classical, ambient, and new age music very enjoyable thanks to the spacious presentation. The C3A035 “C” plug on the other hand, reduces the decay from the “N” plug, giving the notes more body and faster transients. To put it another way, I think that the “C” plug results in more upfront punchy presentation and the “N” plug results in slightly diffused but grand presentation. Between the 3.5 “N” and 4.4 “N” plugs, the general characteristic remains the same to my ears. I do prefer the improved instrument separation and punch offered by 4.4 balanced connection.

The unfortunate part is that no other tuning plugs are available, at the time of this writing. It would have been nice if there was a 4.4mm version of “C” plug to compare with the “N” plug. Furthermore, any other plugs that could meaningfully alter the character of EA2000 could be a lot of fun.

Sound Impressions:​

The general sound characteristic of EA2000 is W-shaped with a slight tilt towards the treble. The treble seemed slightly sharp out of the box but it seemed to have settled over time with use. If you are sensitive to treble in the 5-6kHz area, however, you should try to audition first. The general presentation is slightly diffused, the soundstage is pushed away and expands very wide.



The soundstage of EA2000 and how the bass sounds (probably due to the passive radiator) is unique. Bass notes can be heard well, reaching low, but it happens without pressure building up in my ears. Many bass-head IEMs that I have heard tend to move more air that can be felt in my ear canals leading to the bass “sensation”. With EA2000, when you expect that bass to hit you, the bass notes happen but the sound and pressure seem to escape outwards instead. The sensation of bass “thump” does not happen, or it is minimal. I see this as a polarizing character of EA2000 sound. If I want that bass “thump” as part of the listening, this would not be my go-to set. If I want to listen without fatigue (background listening, relaxing, before sleep, etc) with the right type of music, this passive pressure relief works very well. I can simply sit back and get washed away in my favorite music. I can see this potentially working for people who dislike pressure buildup with IEMs.

To convince myself that the passive radiator is the contributing factor, I compared a bassy song with the passive radiator port closed with a thick tape. Indeed, when I close the passive radiator port, the bass impact improves, the soundstage narrows a little, and the bass extends a little less. I enjoyed the slightly upfront presentation too.

To summarize bass/mids/treble, I would summarize it as follows:

• Bass
  • Extends pretty good for a single DD IEM
  • Slopes linearly into mids without bleed
• Mids/Vocals
  • Stands out well from the mix
  • Slightly dry and crisp but it can be very expressive for the right vocal types.
  • Not warm/lush type
• Treble
  • Comes through clear in the mix
  • Light, feathery, thinner texture

Impressions with Songs:​

Below are some impressions with sample songs and comparisons with my only other single DD IEM that I own, Dunu Zen Pro (ZP).

Every Moment of You, Sung Si Kyung​

• EA2000 (4.4mm “N” plug)
  • The vocal comes through in the sweet spot of EA2000. Good body to the voice without muddiness. Nuances in breath and lips adds excellent emotional quality to the vocals. Really draws me in to the vocal quality of this song.
  • Piano takes a back seat as a light clean background supporting the vocal. Drum kit and strings are present but there to create foundational support for the vocals.
• ZP
  • The vocal comes through a bit thicker, bold, and less expressions from breath and lips.
  • Piano sounds like a grand piano with deep wooden body resonance. Drum kit and strings each occupy their space with individual clarity.

Kimini Muchuu, Hikaru Utada​

• EA2000 (4.4mm “N” plug)
  • Again, the vocalist is the star of the show. Utada’s vocal sounds raw as if listening by the microphone. Various sound effects and layering used for the vocals can be clearly heard. Utada’s voice is not too forward nor recessed, sitting in the right position in the mix and makes listening very enjoyable.
  • Various synth bass phrases used in this track are present and reproduced ok. The bass phrase between 1:21-1:32 sounds too loose and diffused to me. It’s almost strange to hear bass extended like this, yet it eases through without pressuring my ears.
• ZP
  • Like the previous song, piano is much more present here sitting side by side with Utada’s voice. More texture to piano, bass, synths, and percussion. ZP has more mid bass impact, but it doesn’t seem to dig as deep as the EA2000.

Under a Glass Moon, Dream Theater​

• EA2000 (4.4mm “N” plug)
  
  • Intro guitar and synth have nice weight and pleasing distortion sound.
  • Drums come in and the kicks sound slightly sluggish and snare hit sounds muted.
  • Vocal comes in and sits in front of the band.
• ZP
  • Intro guitar and synth are more mids focused and forward.
  • Drum kicks and snare sounds tighter.
  • Vocal comes in and the entire band is playing their own things on the same layer as the vocal (side by side in a plane)

Silver Lining Suite: Drifters, Hiromi​

• EA2000 (4.4mm “N” plug)
  • Strings are spread out wide left-to-right.
  • The piano comes in the center but away. Gives an illusion that I am sitting maybe row 15 getting a perfect panoramic view of the stage of performers.
  • Piano solo – Dynamics comes through well while the cello is thumbing on the side. The stronger notes don’t pierce my ears. Peaks are diffused. Perhaps slightly compressed in the macro dynamics due to staging as well. The piano has a thinner but beautiful timbre to it. Sit back and relax.
• ZP
  • Strings are more intimate, next to my ears.
  • More instrument textures.
  • Piano solo – Some of the notes can sound harsh. Mostly thicker realistic timbre with slight metallic tinge to it. Lean forward, get excited, chase the notes being played.

DAP/Cable synergy:​

LP6Ti7AE > DX320MAX > DX240

EA2000 scales very nicely with improved amplification and difference in DACs. As the drive of the amplifier is improved, EA2000 shows more instrument texture and instrument separation/layering. The bass extension really comes alive and creates an overall stage like a multi-driver setup.

Sony MUC-M12SB1 > Brise STR-Ref7

While the stock cable is soft and nice, I think the stock silver-plated copper is responsible for the thin treble timbre. I found using Brise STR-Ref7 (copper) to give warm bodied sound to EA2000 while sacrificing a little bit of the stage width and resolution. The Sony MUC-M12SB1 cable really takes it to the next level for me. It has a beautiful natural instrument timbre while preserving the spacious quality of the IEM.

Conclusion:​

Simgot EA2000 is a unique take on a crowded single DD IEM market. The added features, notably the swappable tuning plugs and passive radiator, do have an audible result. I hope I managed to convey the key characters of this IEM as I have heard it. My 3.5 score may seem harsh but in the vast landscape of IEM market, the score reflects how I place this IEM from my view. EA2000 has a unique sound and technicality that should be on your list to audition when you have a chance.

I would say that the main takeaways are:

• Wide expansive stage
• Very little air pressure/thump sensation (great for sensitive listeners or for background listening)
• Vocal-centric balanced tuning
• Scales well with source and cables

If your listening preference calls for these characteristics, EA2000 is great value at its current price.

INTRODUCTION:​

In 2023, Simgot had a promising beginning, setting the stage with the acclaimed EA500, which garnered accolades from the audiophile community, myself included. It remains my yardstick for excellence within the $100 price range. Today, I have the pleasure of delving into the EA2000 "Boson," a curious name aside, we'll focus on what truly counts. Simgot has also ventured into the realm of budget-friendly offerings, exemplified by the EW100p, which, I must confess, didn't quite strike a chord with me. Our network of reviewers is currently evaluating various Simgot models, and I'll be exploring more of this brand in forthcoming reviews. Let's embark on this journey, aiming for brevity without sacrificing depth.

FOREWORD:​

• The gear on hand has undergone at least 10-15 hours of use before it was assessed.
• No EQ is ever applied in my reviews.
• For the sake of convenience, I try my best to use a stock setup. Not everyone has access to personal ear tips or cables. If personal ear tips, cables, or accessories are used, you will be notified.
• As I try to be objective, my claims inevitably will be subjective and biased to my personal preference. I cannot stress more that you should take this with a grain of salt for we have different perceptions to sound and what we hear.

PACKAGING:​

The EA2000, which we'll affectionately refer to as Boson throughout this review, arrives in a moderately sized black box, as is customary, with substantial dimensions. The box's front proudly showcases a captivating image of Boson, while the sides bear informative labels detailing some of its key features. On the back, you'll find two frequency response graphs illustrating the impact of the tuning plugs on sound, accompanied by a brief explanation of these plugs' various applications.

Slide the inner box to the right, and you're greeted with the phrase, "Salute to the great pioneers of constructing quantum theory." Frankly, the relevance of this phrase eludes me, so let's swiftly move forward. Within the inner box, a division becomes apparent. To the left, we encounter essential documentation: a warranty card and a special message from the CEO. Ah, now the pieces fall into place. After perusing the CEO's message, the reason behind the name "Boson" becomes clear—it's intricately linked to quantum theory and its implications for the dynamic's acoustic quality. While I may not possess the expertise of a scientist, at least I can provide a glimpse into the name's background.

Beneath the documentation lies the protective case, housing the indispensable cable. Now, let's shift our focus to the eastern wing. Boson securely presents itself, with user manuals and accessories tucked below. This compartment holds a treasure trove of ear tips and tuning plugs. It's time to delve deeper into these inclusions and share my impressions of them.

CASE:​

The silvery gray carrying case exudes an undeniable allure. Its petite and charming size, although not ideal for petite bags, strikes a balance that should snugly fit into most standard bags. At the case's base, you'll find the inscription, "Salute to art and science," while the top proudly bears the Simgot logo and name.

What truly captivates is the interior of this case. It ingeniously houses garters tailored to snugly secure the three tuning plugs. The case itself offers a spacious embrace, ensuring that your Boson rests comfortably without a sense of compression. Additionally, an inner net pouch is thoughtfully included, serving as a versatile space for auxiliary items or accessories.

CABLE:​

The cable possesses an air of premium quality, bearing a striking resemblance to the stock cables typically associated with "Bqeyz" products. However, what truly distinguishes this cable is its robust and reliable modular design. The connectors exude a sense of unwavering security thanks to their screw-type mechanism. In terms of aesthetics, the cable adopts a white silvery hue, which imparts a distinct premium vibe. Although a darker color scheme might have been my personal preference, it harmonizes quite fittingly with the Boson's overall presentation.

EARTIPS:​

okay, eartips inclusions is something that Simgot should give more attention. We have two kinds, or is it? Well, with careful examination, and without clear indication what kind of eartips are these, I find the eartips is only of one kind. They look and feel a lot like balanced eartips, medium bore. I like these tips actually, and I’ve encountered them on Tangzu Heyday and some other sets. But yeah, only one kind here. Just like with my qualms with Simgot’s EA500.

TUNING PLUGS:​

Simgot has consistently been a proponent of tuning flexibility. While I may not personally favor excessive tuning options, it's reassuring to see that Simgot provides tuning choices but keeps it to a manageable one or two alternatives. The tuning plugs, in this case, aren't just mere gimmicks; they genuinely impact the sound profile.

In this instance, the difference in sound primarily influences the upper mids to trebles. The blue-indicated plug, positioned at the bottom, imparts a smoother sonic signature. Conversely, the black plug is more inclined towards reproducing intricate details but does introduce a hint of sibilance. Notably, the blue plug boasts a 3.5mm termination, while the black plug offers both 3.5mm and 4.4mm options. Throughout the entirety of this review, I found myself gravitating towards the blue plug for its sonorous qualities.

APPEARANCE:​

Boson's faceplate flaunts an elegant pearly white color scheme adorned with the distinctive Simgot logo. Crafted entirely from metal, the IEM maintains a weight that never becomes cumbersome to wear. Notably, the base section features a ventilation port, likely linked to its passive radiator design. In terms of aesthetics and tactile experience, there's a noticeable resemblance to the EA500, which, of course, shares a common trait—being a magnet for scratches and fingerprints. Preserving this exquisitely crafted IEM demands an extra measure of care.

INTERNALS:​

Boson takes pride in its unique hybrid configuration, featuring a single 12mm dynamic driver that's notably larger than most. As the saying goes, in the world of audio gear, "bigger is better," and this principle often holds true. However, what truly distinguishes Boson is the inclusion of a passive radiator. Unlike traditional drivers, a passive radiator doesn't produce sound on its own; instead, it complements and supports the primary dynamic driver, which in this case is the 12mm DD driver.

The pivotal question here is whether Simgot has effectively and accurately implemented this configuration. We'll delve deeper into this aspect when we discuss the sound characteristics of Boson a bit later in the review.

COMFORT:​

The wearing experience of the Boson IEMs is undeniably praiseworthy. However, it's worth noting that your comfort journey takes a detour, hinging significantly on the eartips you employ. The stock tips, though, strike a chord of stiffness that could leave your ears somewhat fatigued during extended listening sessions. A noteworthy quirk here is the larger-than-usual nozzle, which suggests a softer eartip might be the sage choice.

It's important to acknowledge the uniqueness of ear anatomy, as what suits one may not fit another like a glove. The shell's size, on the other hand, hits the sweet spot, keeping it lightweight for an overall comfortable experience. In sum, comfort is within reach, but do exercise prudence in your choice of eartips to ensure a harmonious listening journey.

SOUND IMPRESSIONS:​

Boson had the pleasure of partnering with my cherished DAP of choice, the Fiio M11 Plus LTD, and the Cayin RU6. This dynamic duo, along with stock tips and cables, set the stage for our audio journey. Throughout this review, the trusty blue-indicated plug was my steadfast companion. As for the musical source, I drew upon my collection of offline FLACs and tapped into the wealth of Apple Music's subscription library.

The sound stage presented by Boson leans towards the intimate end of the spectrum, bringing the vocals almost "in your face," so to speak. However, there's a silver lining here. Boson exhibits an impressive ability to render reverb faithfully, delivering a sense of head space that adds a layer of depth to the listening experience. But, let's not kid ourselves; Boson doesn't quite venture into the realm of a three-dimensional presentation. I'll spare you the overused and somewhat clichéd term "holographic." We audiophiles often find ourselves bombarded with such buzzwords, don't we?

Instrument placement and imaging stand as the crown jewels of Boson's technical prowess. They transport you to new sonic landscapes, unveiling previously unheard nuances in your favorite tracks. In this realm, Boson proudly strides alongside the upper echelons of audio gear, displaying a level of precision that's truly remarkable. Pinpointing individual elements in the music becomes an immensely enjoyable pursuit, elevating the listening experience to a realm of auditory delight.

The timbre that Boson offers is accurate and well-aligned, but it leans towards the thinner side due to its bright sound profile. If we were dealing with a balanced armature (BA) configured IEM, I'd likely label this as "BA timbre." However, we'll delve deeper into this aspect shortly. When it comes to the mids and bass, they exude a remarkable sense of naturalness. However, it's the treble that doesn't quite march in harmony with the rest. I would consider it a minor drawback in an otherwise stellar soundscape. Nevertheless, treble enthusiasts will find ample reason to rejoice with Boson's performance in this domain.

The speed exhibited by Boson's drivers is a notable feat, worth a moment of bragging rights. It approaches the nimbleness often associated with balanced armature (BA) drivers, and I must say, it's among the swiftest dynamic drivers I've had the pleasure of encountering. This exceptional speed becomes a true asset when tackling intricate and bustling tracks, as they are effortlessly executed. The attack and note definition are swift, leaving no room for ambiguity, and delivering a level of precision that's truly commendable.

Boson proves to be an incredibly easy load to drive, making the addition of amplification an optional rather than a mandatory step. Even when connected to a less potent source, you won't find yourself struggling to crank up the volume to achieve a comfortable and satisfying listening experience. It readily adapts to a variety of setups, ensuring that the music flows effortlessly without requiring excessive power.

BASS:​

Boson delivers the fastest and snappiest bass execution, leaving a distinct impression of punchiness and a satisfying slam. With its near-neutral tuning, this clean bass presentation remains precisely contained without any undesirable spillover into the mids. The result is a remarkably clean bass representation that ensures the lines between the bass and mids remain resolutely unblurred. Drum kicks and bass guitars come to life with a tactile and agile presence that's truly remarkable.

If your heart sings for precision and note definition, then Boson is poised to deliver the utmost pleasure. It excels in providing a listening experience where every nuance and detail is meticulously presented, catering to the discerning audiophile's appetite for clarity and precision.

While the bass performance is undeniably commendable, I must admit that, according to my personal preference, the bass presentation leans a tad too much on the side of speed, at times shying away from sounding completely natural. This characteristic could potentially deter those who prioritize a more lifelike and realistic bass reproduction.

MIDRANGE:​

The midrange, which serves as a home for an array of musical elements such as pianos, guitars, drum snares and toms, flutes, woodwinds, and the string section, has a tendency to lean towards a less lush presentation. Personally, I hold a preference for a midrange that's richly textured, and in this regard, Boson certainly excels. However, there's a touch of nostalgia for the lushness, with a desire for more weight and body. In this domain, precision and clarity are Boson's forte, though it does come with a slight compromise on the weightiness of individual notes.

Vocals, following a similar genetic code, exhibit a noteworthy character. Female vocals, in particular, find a special sweet spot in comparison to their male counterparts. There's no trace of recessed qualities here; in fact, they occasionally step a bit forward, which should certainly pique the interest of midrange enthusiasts. However, for those who lean towards a thicker midrange, it might be worth exploring alternative options, as Boson tends to embrace a more vivid and forward vocal presentation.

TREBLE:​

By this point, it becomes evident that Boson leans toward the brighter side of the IEM spectrum. While this is what sets Boson apart and gives it its distinct character, it also comes with a caveat. Irrespective of the tuning plugs in use, the treble can occasionally veer into sibilance territory. Consequently, it's advisable to keep the listening volume on the lower side.

The black tuning plug, while offering a wealth of intricate details, opens the door to a Pandora's box of sibilance issues. I dare say that Boson could prove to be a fatiguing companion for extended listening sessions; it indeed runs a bit hot in terms of treble presentation. The Cayin RU6, with its prowess, manages to tame the treble, making an R2R setup a wise choice for those with more sensitive ears or those who indulge in marathon listening sessions.

Boson, in essence, doesn't cater to the sensitive folks. Instead, it caters primarily to the treble enthusiasts. It's almost as if it were designed with this particular audience in mind.

COMPARISONS:​

Versus Aful Performer 8:​

With both priced at around the $300 mark, the Aful P8 seemed to be a fitting contender for a comparison. Many aspects of the Aful P8 share similarities with Boson. Let's dive into this showdown and see how these two stack up against each other.

• Aful establishes itself as a more neutral contender when it comes to the overall sound profile. This makes it well-suited for monitoring purposes and appeals to those who prefer a flat and balanced signature.
• In contrast, Boson veers towards a brighter and more energetic sound profile, and it does exhibit sibilance tendencies. Its sonic character is characterized by a livelier and more prominent treble presence.
• Surprisingly, the P8's midrange carries more weight and body, creating a contrast with Boson's midrange, which tends to sound thinner in comparison. This difference in midrange presentation could be a notable factor for those with specific preferences.
• In terms of technical prowess, both Boson and the P8 are evenly matched, showcasing similar capabilities. However, Boson takes the lead in the realm of imaging, demonstrating more accurate instrument placement and providing a heightened sense of precision in this aspect.
• Boson, with its more pronounced bass, delivers a punchier and more impactful slam. On the other hand, the P8 treads a similar path but in a slightly milder manner, with a subtle reduction in the intensity of the attack. The difference is discernible but not drastically significant.

VERDICT:​

As I embark on my third product review from Simgot, a pattern is starting to emerge. It appears that Simgot has a penchant for crafting bright, technically adept sets. In the context of the $300 price bracket, the primary drawback I've encountered with Boson is its tendency towards borderline sibilance. While this characteristic should certainly cater to treble enthusiasts, it may not be the best choice for those with more sensitive ears.

Boson excels in the realm of imaging, providing an impeccable experience, with precision and clarity being at the core of its sonic identity. The passive radiator's influence is palpable in bass-heavy tracks, but it leaves me pondering if it's more of a gimmick, especially given Boson's very near-neutral tuning.

Regardless of whether you opt for the blue or black tuning plugs, the inherent brightness can become fatiguing during extended listening sessions. This bright nature of Boson comes at the cost of sacrificing some timbre in the treble region. While transients are undoubtedly a point of pride, they lean towards the side of being slightly too fast to sound truly realistic.

Boson comes highly recommended for individuals who value technical prowess, favor a neutral tuning, and have a penchant for energetic and clear trebles. It's a set that clearly caters to those with a penchant for a certain type of sonic signature and should satisfy the needs of treble enthusiasts.

I extend my heartfelt gratitude to Simgot and my co-reviewer, Obed Boaz Sanchez, who displayed an exceptional level of patience during the creation of this review, which was admittedly long overdue. I appreciate the opportunity they provided me to explore and experience this adventurous IEM.

Saying that SIMGOT packed the EA2000 a bit extra is an understatement. It comes with quite a large black box with a render of an EA2000 earpiece along with other text and information throughout the initial cardboard cover of the box. Its packaging materials are quite nice and are of great quality. Definitely a bit extra for protection though.

Sliding the cardboard cover is another set of boxes within sets of boxes. You open the compartment you just slid out similar to a book, which greets you another set of compartments.



Suffice to say that the EA2000 comes with a very premium and complex unboxing experience that would definitely leave an impression. Everything are either encased in foam or is packed neatly in a box suited for its size.

The included case is very nice, It's not too big or bulky and it has enough space for the EA2000 along with some other accessories you fancy bringing along with it. The cable is pretty nice too, the termination is shielded by a threaded metal cover to protect the potential weak point and, despite being 8-core, it's not that heavy that it weighs you down but it does feel quite sticky.



The inclusion of not just modular terminations, but also terminations that have different characteristics that is said to change the sound is really great to see. It adds to the value that the EA2000 comes bundled with

Overall the packaging is quite excessive in my opinion but the experience is definitely one of a kind. The included accessories too are great and it more than enough for you to be able to use the EA2000

SIMGOT built the EA2000 using almost entirely out of a shiny CNC aluminum with what seems to be a glass cover over the faceplate which combined, gives off a good amount of heft but not too heavy to be . The overall shape of the EA2000 is universal, but with quite a substantial angular protrusion on the nozzle area.The nozzle also has this lip to help with keeping the ear tip still on the earpiece



A huge vent facing inward is present along with L and R indicators and another smaller vent on the top near the MMCX connectors Near the MMCX connector is a screw with a star bit and an “EA2000” text .

The faceplate has a rose-gold SIMGOT logo in the middle with an interesting background design that also has a rose gold trim, covered by the aforementioned glass.
The overall design of the faceplate is interesting and nice. It’s quite bright wearing it in the ear with white and silver look but nothing too flashy to be too out of place. The shiny coating of the metal can be a cause for concerns for scratches though as it seems to be really prone to it.



I’m quite disappointed that they decided to go with MMCX despite already manufacturing sets with the standard 2-pin. I very much prefer 2-pin because of the compatibility cables that I have and the tendency of MMCX to loosen very quickly is quite a letdown.



SIMGOT packed the EA2000 with a 12mm dynamic driver along with a passive radiator. Passive radiators are different to an active “working” driver in that it’s basically a driver with no acting or moving mechanism that it does itself. It only relies on the changes of air pressure done by another driver therefore making it quite reliant on it and can’t stand on its own. Probably why these have quite a large vent)

Isolation of the EA2000 is just average. There is still some seepage of outside noise but not too much that it would bother your music jamming while on commute.

Because of the chonky overall build, it does stay snug in my ear even with movement but it does hurt my ears after a few minutes. This could be due to the sharp protrusion on the side of the nozzle but it really does hurt whenever that happens especially on the left earpiece.
This is partially fixed by simply ear tip rolling but your mileage may vary

Very efficient in the terms of power. I did not find any issue with powering these and the EA2000 which should be a given due to the driver configuration.

The whole point of adding a passive radiator on audio equipment and most commonly on speakers, is that it allows for a greater reproduction of low-end sound according to some accounts online. The EA2000 does have great low-end performance especially with the blue C3A035 module whilst the black N3A000 is giving a leaner yet much more precise and open sound.



This dynamic of the C3A035 module being more warm and bassier than the N3A000 is consistent and evident during my experience and therefore thinks the C3A035 is some sort of an impedance adapter.



Depends on what music you like but I quite like the black N3A000 a bit more overall but some songs here and there would be better with the blue C3A035.
All thoughts and tests are done with the black N3A000 unless stated explicitly No tests are done with the included 4.4mm tuning module due to the lack of a balanced source.

Bass is one of the primary things a passive radiator is said to benefit from and the bass of the the EA2000 varies depending on the tuning module attached to it. I found that the the black N3A000 offers a more tidier and lesser bass response especially with he depth and amount of sub bass compared to the much more warmer blue C3A035 module.

Mid bass is also the same situation whereas the black N3A000 offers a tidier performance compared to its counterpart. Both of which are still clean and have no bleeding. Everything hinges on where you want more or less warmth using provided modules.


| 𝗠𝗶𝗱𝘀 |

The instruments are more open and extend well compared to the blue C3A035. Vocals are a bit more nasally with that compared to the black N3A000 module but both of which have body which the C3A035 excels and a good extension that the N3A000 delivers.

They don't sound metallic and never once sounded odd or unnatural with the timbre. Shout on both modules is none-existent. I never encountered anything shouty-ness when using EA2000 though sibilance is still present, but is dampened by the C3A035 module.


| 𝗛𝗶𝗴𝗵𝘀 |

The black N3A000 offers a more forward and less capped treble. Details and sparkle is good on the black N3A000 and never sounded thin. The blue C3A035 acting similar to an impedance adapter makes the highs more clearer and more extended at the cost of sounding quite harsh or peaky on really high volumes when using the black N3A000 module. It is up to the user on which configuration would fit their taste but even for me that is quite sensitive to mid-treble, I find them quite tolerable.


| 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹𝗶𝘁𝗶𝗲𝘀 |

This offers competent technicalities especially with the black N3A000 compared to the other module. Layering, staging, and imaging are all good but not the best. This can serve you well for anything like competitive gaming or light analytical work in a pinch and using the blue C3A035 can make for a more immersive sound for things like movies and role-playing games.


|| 𝗖𝗼𝗻𝗰𝗹𝘂𝘀𝗶𝗼𝗻𝘀 ||

Considering the passive radiator of the EA2000 and the lack of any other driver type to offer enhanced high-end frequency performance, this offers a more tamed and relaxed sound that some sets can’t deliver especially those who have balanced armatures that can be a bit overbearing.



Though I’m still unsure if the passive radiator is doing something as this small of an enclosure considering it uses the change in air pressure or if it’s just a damn good dynamic driver on itself with a gimmick of a driver slapped for marketing, I’d still prefer this sound compared to things like the BQEYZ Winter or something similar to it’s price like the HIDIZ MS5.

This is still a matter of taste, some people may find this not resolving enough or is lacking in treble energy, but for a person whose particularly mid-treble sensitive, this is a good comfortable experience.
