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.


  • 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.


Maker: Simgot
Model: EA2000 “Boson”
Configuration: 1 x Dynamic driver. 1 x Passive radiator
Pin system: MMCX
Termination plug: interchangeable 3.5mm, 4.4mm

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.



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.



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.



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.



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.



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.


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.


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.


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.


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.


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.


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.


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.

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.

After the success the SIMGOT received with their very highly regarded EA500, they also offer other offerings throughout various price points and this new release aims to target the ever so competitive and lively $300 category.


The EA2000 is priced roughly at $320 and is sporting a 12mm dynamic driver and a passive radiator along with an MMCX connection and swappable terminations is said to be tweaked to affect sound, SIMGOT aims at the releases such as the HIDIZ MS5 and AFUL Performer 8 against their more hybrid configurations.

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.


| 𝗨𝗻𝗯𝗼𝘅𝗶𝗻𝗴 & 𝗔𝗰𝗰𝗲𝘀𝘀𝗼𝗿𝗶𝗲𝘀 |

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.

𝗜𝘁𝗲𝗺 𝗕𝗿𝗲𝗮𝗸𝗱𝗼𝘄𝗻:

Gray magnetic case
White 8-core SPC MMCX cable with swappable terminations(2.5mm/3.5mm/4.4mm)
6 pairs of normal-bore eartips(S/M/L)

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

| 𝗕𝘂𝗶𝗹𝗱 & 𝗗𝗿𝗶𝘃𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 |

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 |

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.

| 𝗖𝗼𝗺𝗳𝗼𝗿𝘁 |

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

| 𝗗𝗿𝗶𝘃𝗮𝗯𝗶𝗹𝗶𝘁𝘆 |

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.

|| 𝗦𝗼𝘂𝗻𝗱 ||

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 |

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.

SIMGOT is an experienced chinese audio company that have been around for more than 5 years, but get notice lately due to their quite popular EA500 single dynamic driver IEM that put the bar extremely high in term of sound performance under 100$.

Personally, i've discover this company near a year ago with the EN1000 IEM which I adore and highly praise, then like everybody else, i've been blown away by their EA500 and officially become a Simgot fanboi.
This push me to test their flagship model call EA2000 Boson.

The EA2000 is priced 320$ and use a 12mm double magnetic dynamic driver with an impressive magnet flux force of 1.9T, as well, it's perhaps the first IEM using a passive radiator that permit to control the resonance and add a sens of extra speed and control to the sound. So, the EA2000 are 1DD+1PR hybrid we can say, and they take acoustic seriousness to next level.
Let see in this review if the EA2000 offer a sound performance that is truely above average.


The craftmanship of EA2000 is simply mind blowing and can put to shame IEM at 4 times it's price. It's litteral perfection in term of well machined and matched IEM part, their no amateurish imperfection I can find even with passionate macro pics. It's a piece of industrial art at it's finest, that is captivating to look at, but very sturdy too and not that easy to scratch even with a mirror finish. I rarely rave that much about construction and believe me, my eyes are sharp to find built cons, especially when the price is higher than 200$, but I was prepar for greatness with both their EA500 and EN1000. So, with Simgot you don't have to be worry about the IEM construction, for the cable it's a bit of another story....which i will devlop further.


As seen, the number of fine details in construction aren't left to randomness, it's both thinked for acoustic and elegant beauty, it have a mature audiophile look to it and doesn't look like a toy at all. The shell is soft, the metal material isn't stated but feel thick and durable and not too heavy even if not light, the mmxc connector are solidly embeded in the housing. The nozzle is long enough and angled. It seem the front protuberance tend to push IEM weight into your ears too, so even with cable that don't have ear hook these have a solid fit. The built is truely amazing. Isolation is OK too, and sound leakage is average, which is to be expected with open front venting for the passive radiator.


Now, I would like to praise the cable too, which is made of great quality silver plated 8 cores, is soft, thichk and well, feel sturdy until we begin to play with the tuning module plug. If you follow my review, you perhaps know how much I hate this type of screwable plug, especially with FIIO cables and let say it certainly damage durability potential of modular cable in general and this one is no exception. In fact, the interconnection get loose and it seem one of tuning plug already begin to unglue its plastic part inside metal part. As well, at they end, i'm not a big fan of the so called tuning effect on the sound which is very similar to using impedance adapter to mess up with dynamic push. All in all, i'm not a fan of this cable and will never use it after this very review.


The packaging is very nice and come in an elegant box. Number of accessories is OK but lack varied ear tips choice ,which seem typical for Simgot. It's a bit puzzling because ear tips is very cheap and we expect a good amount of them with a flagship IEM of this price, yet we got...3 pairs. The carrying case is beautifull but a bit small. And well, I already tell you what I think of the cable.



Let's clear this up right away: the EA2000 aren't basshead IEM at all, and while I would call them Bass-Fi in term of low end quality, the quantity is just average, perhaps about 5db mid and sub bass boost. But it doesn't mean it's bass light or lacking extension or rumble too.

In fact, these are treble monster first and foremost, it's the highs quality and speed and sens of openess that hook and engage you first. After it's the impressively wide and deep soundstage and then the bass....and lastly, the mid range which take a step back within a vivid W shape tonal balance.

Yes, sharp, speedy and highly engaging W shape. Edgy bass, open bright mids and crisp treble is what the EA2000 offer in a very glorious way. Think about a Sonic Memory SM2 with just a hint more bass and a notably more sparkly and extended treble, and your not far from what this marvel have to offer.

These aren't for the faint of hearth, nor little princess ears, the EA2000 are near analytical, highly revealing and sharp sounding and will please more the treble head than the basshead.

But this bass scream quality. It have this definition edge for kick drum that I rarely found with any other IEM, it's speedy, textured, super well separated from mid and extend deep with a airy resonant yet controlled rumble.
It's more thumpy than rumbly though, so you have greater mid bass boost than sub bass boost, it's not a chunky bass that feel thick in it's roundness. Very unique and very addictive is the low end since it don't need crazy boost to be authoritary here, the presence is very clear and detailed but don't lack density, the punch is fast and tight, with fast decay and clean resolution.
And it have this unique mid and sub bass layering which permit you to follow bass line accurately as well as kick drum sharply and yes, feel the punch too without both mixing up like it often happen even with great IEM.
But, still, i would have low a bit more boost! Especially in sub bass region which i find a bit thin, i'm more attract to kick and slam than rumble and bass line extension with the EA2000.
But would I will be able to follow sub bass pitch that precisely in the track ''DJ Cam bro'' from Skeemask, which basshead IEM tend to render in muddy or one pitch way? I don't think so.
Now, if I analyze contrabass extension, i discover the ''passive radiator'' trick, which add resonance sustain as an extra sound layer, it doesn't work that well for this instrument that need more linear and deep extension down to 20HZ, so double bass is a hint ''slapped'' sounding here, but clean and well layered still. I do my best to nit pick some con!

And well, it will be easier finding cons in mid range, even if it's so far from being bad it will be too agressive in upper mids pinna gain for some. It's not a big issue for me because it's well controled, clean and have barely no sibilance, but it can be a hint shouty in higher pitch loudness, like when a soprano go louder in a song. The mids are crisp, open, clean, detailed and impressively transparent with rich texture and even some note weight, which surely come from the ''passive radiator'' since I can't explain why the piano sound so good and impactfull even if edgy in definition.
Again, the EA2000 deliver a unique musicality that is both technical and dynamic in rendering. The attack have a sens of hit to each note and a natural and clean decay, so those piano note sound superbly define, full in presence, not warmed or thicken in density yet flexible in the impact so you got both the lead impact, fast sustain then a long and clean release that is utterly transparent.
While i would call the timbre as ultra realist, it have a hint boosted texture but never to the point of being grainy, it's richly textured and not plain thin and even less lean, it's a vivid mid range here with lively rendering and it doesn't feel recessed. The real con for me is for vocal, sometime violin too can be a bit too agressive, it's in a specific pitch region so at loud volume it will suprise the ear negatively.
So yes, the female vocal are a bit shouty and compressed in presence, it feel stock in my head too and their some rare instance of sibilance, pairing the EA2000 with warm source can help for ex, both Hiby RS6 and Shanling M0pro soften upper mids and thicken widen vocal presence, to the cost of stoling air and clarity.
All in all, the mids are open, crisp, fast in attack, highly resolved and transparent and not warm, nor super thick or lush sounding, so I would not suggest the EA2000 for mid centric audiophile.

Then the crazy speedy crispy treble come in and let say you can't forget it easily, even after more than 100H of listen this extremely revealing and agile highs still blow my mind when listening fast percussions, but not only since it add this grunt to bowed instrument like violin, but to electric bass and guitar too. It's edgy in a masterful way where the sharpen definition is fully restitute in texture and presence and don't sound thin, half cook or over soften in definition edge.
That's the magic here, a treble that is brilliant and shinny, sharp in rendering but full in tone and body, their no blunted edge to definition and the level of micro details is very high. While spiky, it's not the type of highs that will just boost one part of texture, or make bowing of strings sound in your face and distracting, it certainly vivid and a hint agressive, but the control is so fast that it don't let loose the sustain-release of this energic attack.
Sure, the cymbals will not be tamed in loudness, but they will not go splashy and mix everything in noise. Whatever instrument the EA2000 deal with in high range, it will be lively, highly exciting and clean in singular resolution. The Saxophone playing will be able to offer every details of it's attack shift, from bow snap to vibrating air playing, you will be captivated by the ultra realistic presentation of violin too. We are in high fidelity territory here, and for an entry level mid range price this is fabulous.
As well, it extend far but without picking up unwanted noise or background hiss, so their a tuning trick here to magnify sens of clean clarity and airy openess. I'm very demanding when it come to sparkle, and the EA2000 deliver that in full glory too. This kind of treble quality isn't expected in this price range and I think the ultra powerfull magnetic flux in tandem with passive radiator is what permit to achieve this miracle.

And then the Soundstage, another highlight of near all Simgot IEM, they know how to add sens of air and openess that benefit deepness ot spatiality. It's open and surround you widely, it's tall too but in a well balanced way with wideness and deepness. I know i'm listening to a special IEM when i can dig super deep in spatiality and find musical cue, and this is what the EA2000 achieve, effortleslly.

With this kind of spatiality, it sure benefit the Imaging capacity too which is near monitor like in the accuracy and sharp positioning. This is particularly evident with acoustic music, like with the album ''Poetry'' from Adam Baldych Quartet....i don't struggle at all to pin point piano, kick drum, percussions and violin, which are layered with great transparency. Again, this is incredible to get this kind of high fidelity experience for less than 500$. Clean and sharply position instrument that doesn't have blurred or overly recessed frequencies range is what we seek with a well balanced yet vivid W shape tuning, TOTL way.

What about the tuning plug? Well, their just 2 type of slight sound difference we can get and its between the black and blue 3.5mm plug. The black is what I review above, it's the stock sound. The Blue amplify sens of openess a bit but seem to brighten upper mids even more. As well, stock cable with black 4.4 or 3.5 plug seem to tame the dynamic heft, so at they end, i'm not sure to know what's going on with the impedance of the plug and prefer using my own cable.
Eartips is very important, while for source, i would suggest a smooth but clean one, even if I say warm source do good match, it need to have a clean and deep spatiality so the EA2000 can show you it's true competence.
These aren't hard to drive and will not scale up with amount of power of your source but amount of DAC quality, like SNR, THD and clean background noise floor. In fact, at 23ohm of impedance and 114db of sensitivity, they are not too sensitive nor too hard to drive.


VS RAPTGO HOOK X HBB (1planar+1 piezo=260$)

HBB is warmer and more balanced W shape with thicker and fuller mids range but less clean and crisp resolution.
The bass is darker in definition and embrace-thicken-warm more the mids, it have more sub bass boost and greater slam, EA2000 bass is more define in punch, more textured and transparent, faster but thinner in density and less thick in rumble.
Mids are crisper, more open and transparent with the EA2000, it's cleaner and airier while HBB is warmer, more hazy and smooth, more dense and euphonic in timbre making vocal less prompt to sibilance, less thin and dry, more pleasant an natural as well as wider and more holographic in presence.
Treble is sharper with the EA2000, crisper, sparklier and more detailed, airy, brilliant and open, more agressive too compared to thicker and crunchier but leaner treble of the HBB which is fuller sounding and more organically balanced.
Soundstage is wider and taller with the HBB, but notably deeper and cleaner with the EA2000.
Imaging is superior with the EA2000, which have sharper instrument separation and definition but a more recessed center stage.

All in all, we will break the myth that planar is superior to dynamic driver again since technical performance are notably superior with the EA2000, while I find to smoother darker lusher and fuller sounding tonality of the Hook X HBB more cohesive, natural and musical.

VS SIMGOT EN1000 (1DD-190$)

The EN1000 is smoother sounding, offer a more organic W shape while the EA2000 is notably more vivid and sharp sounding, with more edgy note definition that more softed one of EN1000.
The bass is more textured and extend deeper with the EN1000, its better define in kick and mid bass since even bass have a definition edge to it, while EN1000 bass seem more warmed and blurry in mid bass definition, less fast and controled in attack and less well layered too.
Mids are denser and warmer with EN1000, less energic but wider in presence, so timbre feel a bit more natural and thick than thinner crisper mids of EA2000 that have better and cleaner resolution and transparency but hotter upper mids.
Treble is notably more open, airy and detailed with the EA2000, it dig more micro details and offer edgier definition. Highs have more snape and bite too, which make for ex the violin sound very softed in attack lead with the EN1000. Attack speed is superior and offer cleaner timing for complex fast percussions in jazz or rock.
Soundstage of both is very impressive and they are on par, with perhaps hint more deepness for the EA2000 due to it's extra crispness.
This inflict on imaging rendering which is more analytical and accurate with the EA2000, due to edgier definition of each instrument, separation is clearer and more precise in positioning.

Well, it's evident that technical performance of the EA2000 is superior here, but tonality is more agressive than smoother and slightly lusher sounding EN1000, yet, i find more exciting and engaging (and impressive) the EA2000 even if not as well balanced tonaly.


I didn't know what to expect with the EA2000, and this is due to my obsession about the passive radiator hybrid technology which at they end didn't inflict as much as I think on bass quantity but certainly blow my mind in term of quality. This is the shock here, i was expecting a fun, near basshead yet vivid and technical sounding IEM, but it was a balanced W shape I got instead, something reminescent of my beloved HZsound Mirror but on steroid.

So, while I would not call the EA2000 fun, i would certainly not call them boring at all since it's the type of vividly crisp, snappy and impactfull musicality that wake you up.
Simgot isn't your typical chinese audio company at all, they push technical performance bundaries and make it available for the mass in a refined way, it's not about fake clarity here, nor about V shape bassy wow effect, it's about mature engaging high fidelity sound rendering.
I rarely if ever use this term: High fidelity. But for the EA2000 I feel it's the right term.

The EA2000 are extremely engaging to listen too, offer technical performance that can compete with kilobucks single DD IEM and this isn't a click bait statement but my own truth. But it doesn't mean they are perfect, the tonality will be hit or miss even if it's not wonky, unatural or unbalanced. And it's due to mid range ''ideology'' approach, which fan of Harman target will find appealing due to the focus on presence before fundamental harmonic. Let simply say they EA2000 are technical sounding but don't lack any dynamic heft, quite the opposite, it offer a sens of captivating urgency to your music.

All in all, I love them alot. And the EA2000 confirm that Simgot is among the best chinese IEM companies right now. Their no doubt I will follow their evolution closely, even if I hope they will diversify their tuning and don't fall into an house sound that limit the musicality offering.

Highly recommended!!

PS: I want to thanks Simgot for sending me this review sample. I have no official affiliation to this company, and just follow them by passion. As always, those are my honest and unbiased audio impressions and opinion.

@domdesilva their 2 other great single DD, one between harman and DF neutral name Sonic Memory SM2 and the other more similar to Kato, pure harman, Aune Jasper (way crisper and more transparent with deeper leaner bass, very good very underatted imo but like all harman it have thin mids). Tanchjim Oxygen 2 worth being on your list but I havent try it
Mini Mike
As another owner of the ea2000 this review is really spot on. I was curious if you experienced a low rattling/screeching sound when vocal tracks were played. On my set only the right piece seems to be like this and even though I changed cable and tips it still is like this. Did you burn them before using them?
any comparison to FD7 please?
