Simgot EA1000 "Fermat" In-Ear Monitor

I will be focusing this review on sound quality to make it as short as possible. So you wont get bored reading it.

The Simgot EA1000 (220 USD) is a mid-priced single-dynamic driver IEM with a passive radiator to enhance the bass.

The shell is metal and chrome-finished, and the faceplate is made of glass. The weight is on the heavy side, and the size is medium. The looks and feel are very elegant, and my unboxing experience is very positive.





Eartips and Cable:
The stock tips look and feel very good, and the cable is above average in quality as far as stock cable is concerned.

Pairings:
For this review, I used ePro EP00 medium eartips and Tripowin Seraph cable. I would like to emphasize my use of the ePro EP00 tips, as this IEM sounds the best with this tip. I use the red ring nozzles as I cannot take the aggressive sound of the other two nozzles that's included. I included photos of the graph I measured so you can see the frequency response of each nozzle. (see photos). Note: The peak at 8 kHz is a measurement artifact.
For the source, I use a Moondrop Dawn Pro dac/amp connected to an Android phone. This IEM sounds its best with warm-sounding sources.

Tonality:
A moderate V-Shaped sound signature that is slightly leaning on the bright side, even with it's mildest tuning nozzle, the red ring nozzles.




Technicalities:
The sound stage has average width with decent depth. They are not the biggest I've heard, but they don't sound cramped in and claustrophobic; there is a good amount of space within the sound stage, so it feels like you are in a club or a discoteque kind of environment at most on some songs.
The imaging is quite good, especially when used with the ePro EP00 eartips; they are well focused and could project sounds coming from behind. I thought someone was playing a musical instrument behind me, outside the wall of my house, and I had to pause the music to check. The left-right imaging is also decent, but it doesn't project very deep, making the front-back separation just average, but still decent enough not to make this IEM sound claustrophobic.
The detail retrieval is impressive, but the micro-detail is not the best that I've heard.
The power handing is very good. The sensitivity is above average. The dynamics are bubbling with energy. This is not a boring IEM, for sure.

Bass:
It is MId-bass focused and tight, but not devoid of sub-bass; there is still audible sub-bass that can be enjoyed. The upper bass is tight and clean and doesn't encroach on the lower mid-range. The overall bass sound is textured and detailed, and not a trace of muddiness can be found.

Mid-range:
The male vocals are noticeably behind the female vocals in their presentation. The lower mids are more recessed than the upper mids. The upper mids can sound too forward with the wrong pairing of Dac/amps and eartips. The overall sound of the mid-range is clear, detailed, and highly resolving, yet it still sounds musical.

Treble:
Energetic and slightly elevated, but not sibilant and harsh. It has impressive detail retrieval, but the micro-details lag behind. This has the best detail retrieval in a single DD IEM I've heard so far, but my experience with single DD IEMs is limited, so you can take this with a grain of salt.



Comparison method: I A-B them while writing this to avoid errors as much as possible. The eartips used in all the sets in this comparison are the ePro EP00 medium eartips.

Versus Kinera Celest PhoenixCall (110 USD):
They have similar tonality and timbre, with PhoenixCall sounding more recessed in the mids. Both have similar detail retrieval, but the PhoenixCall has a little more micro-detail nuances. Both have similar-sounding bass, but the bass on the EA1000 is more detailed and textured and seems to go deeper too, but by just a small margin. The bass on the PhonixCall is a little warmer.

The EA1000 is more prone to being shouty in the upper mids when paired with the wrong source; the PhoenixCall is more tolerant regarding the source pairing.

The PhoenixCall is an energetic-sounding set, but the EA1000 is more so. Both can take high amounts of power and can go very loud, but the EA1000 leads in this regard, albeit only by a small margin.

Both have a musical and engaging sound.

The PhoenixCall has a bigger sound stage.
The EA1000 is more natural-sounding; not that the PhoenixCall isn't; it is, but there is something about the sound of single-dynamic driver IEMs that makes them sound more natural than IEMs with multiple driver configurations.

So which one should you choose? The EA1000 is more expensive but has a classier-looking shell and feels more expensive as a whole, including the packaging and the unboxing experience. On the other hand, the PhonixCall cost only half the EA1000 and also has very good packaging and shell design and offers similar sound quality.

My advice is that if you can only afford the PhoenixCall, get the PhoenixCall; you are not missing out much, but if you can afford the EA1000, buy it. There is something so good about its sound that is impossible to describe in words that makes it worth its price.




Versus Hidizs MP145 (160 USD):
The MP145 is a warmer and bassier-sounding set; it has more micro-details and nuances in sound. The treble is delivered with more finesse and delicacy. The sound presentation is on the relaxed side and could sound a little boring and lacking in dynamics. The mids are more recessed. The sound stage is bigger. The bass could sound a little boomy and lack control when paired with an amp that has a high output impedance.

The EA1000 is more energetic and engaging. It has more macro-details and resolution. The sound presentation is closer and more immediate. The transient response is faster. The EA1000 has better imaging. The bass is much tighter, cleaner, and more detailed. The sensitivity and power handling are higher. Overall, the Simgot has a clearer sound.

So which one should you get? Get both. The MP145 is an excellent example of a planar IEM, and the EA1000 as a single dynamic driver IEM. Personally, if I could only have one, I'd get the EA1000.




Versus Xenns Mangird Top (550 USD):
The Xenns Top is a hybrid set that consists of a 10mm dynamic driver and 8 balanced armature drivers. It sounds more neutral and less energetic. It has more macro and micro-details and is more resolving, but not by much.

The Xenns Top has a bigger sound stage and better imaging and layering.

Both have very good power handling and sensitivity.

The EA1000 sounds more engaging and fun to me, and the Xenns Top sounds more serious.

The Xenns Top feels lighter and less expensive; the EA1000 looks and feels much better, IMO.

Personally, if I could only have one and have to do it all over again with the knowledge that I have now, I'd get the EA1000; it is less expensive and more fun to listen to.




Versus Simgot EA500 (70 USD):

The EA1000 is more energetic on its mildest-sounding red tuning nozzle than the EA500 on its wildest black tuning nozzle, but even so, the EA500 sounds so thin and fatiguing that I can't listen to it for more than an hour, while I can listen to the EA1000 for many hours without fatigue.

The EA1000 is better in every way than the older and less expensive EA500; it has more extension in the bass and treble, a much bigger sound stage, better technicalities and tonality, is more resolving, and, as I said, is better in every way.

The EA1000 is an excellent upgrade to the EA500.

Pros:
+ good looks
+ excellent build quality
+ excellent packaging and accessories included.
+ excellent sound quality
+ Impressive resolution
+ very good tonality
+ fun-sounding

Cons:

- sound stage is not the biggest.
- Micro details are not the greatest.





The big question is: is the EA1000 worth its price premium over the vast majority of budget IEMs costing 100 USD and below in terms of sound quality improvement? My answer is unequivocally yes. And considering the whole package, even more so. Would I recommend the EA1000 to my personal friends? Yes, if they can afford it.

If you're looking for an upgrade in sound quality, design, and build quality from your $100 and below IEMs, you can afford it. I highly recommend the Simgot EA1000.

Simgot EA1000 Fermat

Video Review EA1000. Please Support!

This year has been a busy year for our friends at Simgot. Earlier this year, I think it is safe to say that the community was wow-ed by the level of detail that was on offer by the EA500.

That was followed by by cheapie offerings with the EW100 and EW200 which bottom shelf divers happy. Especially the EW200 where the tone quality is just so good. It was just full sounding which is very newbie friendly. If this is your first IEM video and looking for what to buy? Consider the EW200.

But today we are not here to talk about what Simgot has released the past year. We look to the present and future. Today we are talking about the EA1000 Fermat.

Let's just start things off with an unboxing of the EA1000 Fermat, we are greeted with a purplish box that has FERMAT’s Last Theorem printed on the front of it. This gives me PTSD from the times in school when I had to do advanced maths. I cannot do advanced math where things don’t make sense.



The top of the box does show the product name and when you flip it to the back you are greeted by not one but 3 different FR curves! Basically, the EA1000 has different nozzles for you to choose from and these are the 3 FR from the 3 nozzles.

After shaking the sleeve off, the box pops out, You then have the Fermat Last Theorem 3D Pop-Up Card Thingy which brings me back to my youth when I always wanted pop-up books but my mum thought that it was a waste of money as much of the book is taking up by pointless 3D popping up things which reduces the literary content.

Anyways, Fermat’s Last Theorem was thought to be impossible until 1995 when Andrew Wiles published something to show that it could be solved. I guess the story here is to never give up, love always wins and always eat your broccoli and Brussels sprouts.

Below that you have the IEMs sitting in their own compartment. Removing the first accessory box you have some sponges and when you go treasure digging in them, you will find all the interchangeable nozzles for nozzle-changing goodness.

The longer Accessory box has 2 sets of the same ear tips good for clumsy people such as yours truly who loses things all the time. You also are given more O rings for the nozzles and also some literature.
In the last box, you will find the IEM case itself. It is magnetic and can close quite easily which is nice. Inside it is the cables of the IEM as well.
All in all, the packaging is pretty well put together especially considering the price. A pretty complete package.

Build Quality
The EA1000 comes in a mirror finish and as you know mirror finish is quite a pain in the butt to make simply because any finishing error can be easily seen. I’m happy to say that mine came in a pristine condition.

At the front of the IEM, you have a beveled glass faceplate with some pattern underneath it. I think this really makes the EA1000 look really premium.

On the back of the chassis, you will see the opening for the passive radiator near the top of the IEM. Below that is the usual raised section as seen in the EA500 where this makes the IEM so much more comfortable to use.

The nozzle here is interchangeable, but it does have the red-ringed nozzle as the default. This review will be based on it.

The EA1000 comes in an interchangeable 2-pin termination. The cable provided is a silver-plated cable OFC litz cable.

Driver-wise, the EA1000 has the second-generation dual magnet dual chambre dynamic driver that Simgot uses. The diaphragm, although no mention of what material was used, is a beautiful purple gold annoy that has superior rigidity and lightweightness.



Sound
As there are 3 nozzles in the EA1000, I will base the review on the default nozzle, the red ring nozzle. Tonally, the rest of the nozzle does change the upper frequencies somewhat but does not change the character of the IEM. There are 3 nozzles here, A Red Ring, a Black Ring, and Gold.

The Red Ring is based on the Harman 2019 curve and it is also what I feel to be the most balanced version.

The Black Ringed Nozzle is great for folks who enjoy sparkly treble with a little more energy.
The Gold Nozzle still has great treble characteristics but it isn't as sustained as the reds or blacks.

But overall, the nozzles do not change the tonal character of the IEM.

The EA1000 is a natural warm IEM. What sets it apart from others in the market with such tuning is the inclusion of the Passive radiator. I found that the inclusion of it really makes bass very resonant and very lifelike. It just augments the texture of bass making them airy, a little more diffused but more importantly very natural sounding.
Bass
The passive radiator makes a huge difference in the tone of the bass of the EA1000. The way it changes tonally with added resonance and realistic decay is simply delectable. By no way, is the bass texture of the EA1000 like that of an open item which dissipates way too quickly.



Bass is fast, with unbelievable texture and very natural decay. I would say that bass is airy sounding yet full at the same time if that makes sense.

Subbass extension is extensive on the EA1000. You get good levels of visceral bass impact that is mated nicely to a robust mid-bass offering.

These are not bass-head IEMs, but neither are they anemic. I found that Simgot has done a good job controlling the quantity of bass and increasing the resolution and more importantly texture of bass. The improvement in texture does make bass have a 3D-like rendering.

Midrange
The midrange on the EA1000 has an upper midrange focus which really helps female vocals. Female vocals just sound very delicate and sweet. The resolution here is a whole level up from the EA500. There is an airiness to the tone that again coalesces well with the fundamental female tones which is exhilarating.

Male vocals are full-sounding but not overly full or grunty. It again has a very airy yet full-sounding texture which really bolsters a new dimension to listening. I really enjoy this new added subtlety to the overall tone.

Instruments that dwell in this range also is very articulate sounding. Pianos are very crisp and clear with a very high level of finesse.

Treble.
I bet by now you have already guessed the character of the treble. It is effortless, smooth, and airy.

It really adds a very good level of perceived space.

But covering the basic aspects of treble, your cymbals and crashes are very well defined. Crashes especially have a delicate radiance that will disperse very naturally as well.

I do feel that the treble here is very effortless and smooth. Almost rivaling IEMS uses the Sonion EST driver that will probably cost quite a few pretty pennies more than the EA1000.

Soundstage
Width and Height
Simply stellar when it comes to width and height. The Simgot is class-leading at the price point when it comes to soundstage reproduction.

It just renders staging beautifully wide and tall.

Depth and positioning
It has very good depth rendering as you can easily tell how far the instruments are. Positioning again is beautiful. There is this airiness that makes positioning believable.

Comparisons.
VS Kiwiears Quintet
I do find the Quintet to be rather similar to the EA1000 but with a different tonality.
The Quintet is another IEM with excellent resolution that is achieved with 4 different driver types. It will give you a very good resolution performance but tonally, it isn’t as consistent as the EA1000 with the beautiful airy rendition of music.

VS Tanchjim Kara
The Kara is priced just a bit cheaper than the EA1000. The Kata has quite a warm character which is quite different from the EA1000. I do feel that the EA1000 has better resolution characteristics with a nicer airy tone.

The Kara is just a very safe warm tuning that was a type of signature that was popular quite a while back. In terms of resolution, the EA1000 is ahead.

Conclusion.
The EA1000 is an IEM that I really like. It just does so many things right with excellent levels of detail that has full bass that is resonant and airy.

It is certainly very natural sounding and I found myself grinning ear to ear when listening to them.

Simgot was kind enough to send in the EA1000 for review, as part of an Australian audio review tour, I wasn't paid for the review, any opinions, thoughts are my own.

Design musings

Development of in ear monitors is accelerating as manufacturers compete for best in class. Single Dynamic driver IEMs would seem to be the most basic design, with products on the market for less than $20. And yet Simgot is selling the EA1000 at $220.

The reason is they have taken the design and developed it to the Nth degree. I don’t pretend to understand what sputter deposition purple-Gold diaphragm technology or dual magnetic and dual chamber technology means. I have an inkling of what Passive radiator technology is designed to do but I will leave others to explain that. What I understand is the sonic results of all this development.

Equipment used to test.

I used my Hiby R3 Saber 2022 DAP with a NiceCHK 2.5mm balanced cable and TRN T ear tips. Listening to my music collection of FLAC files. I get a nice deep seal with these tips.

A note on fit and comfort. In size the EA1000 is similar to the Simgot EW200 with a similar metal body. But for some reason the 1000 fits deeper in my ear canal to the point where the IEM almost seems to sit flush. Everyone’s ears are different, but we have a bit of synergy going on here.
Drivability

I use the DAP set to high gain and when driving 7Hertz Legato or Hidizs MP145 I use a volume setting of 45 (sometimes a little higher) . With the Simgot a volume setting of 35 gives me equivalent sound pressure and boosting to 40 I find unnecessary and no advantage.

The Sound

This IEM impresses from the word go. Its tone is rich and tends to the warm side. The bass is fast, deep and well textured, allowing rumble and thump when required and never intruding on the midrange. Vocals have a forward placement with natural timbre and an intimate expressiveness. Vocal lovers will enjoy the EA1000. Singers have room to move in an expansive space with great left to right width and enough height and depth to create an immersive soundscape.

One of its great strengths is handling complex compositions. Instrument separation is first rate as is detail retrieval. The EA1000 never gets flustered or congested. Each element of a song is audible as recorded and the sound is coherent and compelling. Songs breathe!

Treble details are refined, airy and extended, never too hot or overbearing. Indeed, the cohesive tuning of this IEM is its big strength. And above all its is a MUSICAL IEM.


Conclusion

I titled this review. The Goldilocks IEM

If you don’t know the children’s fable, it’s a story about porridge and a little girl who eats the three bears porridge. Daddy bears porridge was too hot, Mumma bears porridge was too cold but baby bears porridge was just right! The Goldilocks zone!

The Simgot EA1000 presents each aspect of the audio spectrum as “just right” to my ears and I’ll be saving to get my own set. Highly recommended.

Simgot EA1000 Fermat

"More of everything"


DISCLAIMER:


This unit was sent by Simgot. However, they do not hold any of my opinions.



WHAT’S IN THE BOX?


Watch my unboxing here:





Pretty good! You get more than what you need!


1.) The cable is pretty amazing in quality. I never thought I'd have orgasms from touching a freakin cable lol. No really, they feel amazing and built like premium.


2.) Nice eartip presentation. I think 2 sets.


3.) Nice looking case. Can pass as jewelry case for your wife haha.


4.) Interchangeable nozzles. But honestly, I only use the black ones.


5. Overall good unboxing experience. A lot of attention to detail.




BUILD and COMFORT


- they are beautuful. They arent really that heavy than it looks. You can see the placement of the passive radiator that looks like it also pushes air to your lobes.


Comfort seems good. Simgot hasnt really failed me in this department. They are flush and lightwreight.




SETUP:

-Shanling M3X using UAPP, Hiby, apple music and stock player

-stock cable

-stock eartips




SOUND PROFILE


Watch my final review here:





The signature is approaching V shaped due to the emphasizes bass texture and elevated upper mids and treble.


Although the vocals can come across forward at some tracks, you'll loose catching up with voices when all instruments start playing together, at least in my library.


Mids actually sound clean, but can sometimes sound digital. Still I am giving it a high praise because Mids arent just vocals. Instruments sound amazing with the Fermat. Strings, pianos, etc. have great harmonics and overtones.


Treble can be a dealbreaker. It has some elevation in the upper mids and past 10k that might be a con for some. Personally, I do find them a tad forward for my preferences. Although the quality is good because cymbals sound crisp and nuanced, but they can be overbearing on some metal tracks.


The bass is what makes this set special. That passive radiator is doing something. The tactility and texture it offers is as close as you can get IRL. If you've ever played drums, you will notice how easy it is to catch rolls.




PROS

that bass texture and tactility is god send


instruments sound great overall


a lot of micro nuance. Enjoy hunting


great overall package and sound for its price



CONS

forward upper mid and treble can be bothersome


vocals can be recessed in some genres


not the best at center imaging. Not the deepest stage as well



SCORING

-Please be reminded that my scoring is always based on its price range.


TUNING - 2.5

BASS - 3.5

MIDS - 3

TREBLE - 2.5

TECHS - 3


P.P SCORE = 14.5


Rank- S+ ( exceptional for the price range, consider saving if you can afford)



Check my scoring here :


https://docs.google.com/spreadsheets/d/15WhgCgiMzWfF3ccgB8SK5-Cg7m87kpIShtxsyg2u-AI/edit?usp=sharing



GRAB SCORE:

This is easy, I just rate the set whether I would grab them for listening. Very subjective.


- I will never touch this again


- I grab if I remember


- Can be part of my rotation


- I break my rotation and grab this one today


- *** rotation, I’ll listen to these for the whole week


- Im selling everything, I will only listen to these haha.



Fermat GRAB SCORE: 4


Yeah, I can listen to the Fermat for the whole week and forgot other IEMS I have.


COMPARISONS


Binary Chopin

- I really like the Chopin. In fact, when I got to listen to them again, I was reminded why I ranked them S. But I have to say that the Fermat is just technically more capable. You hear more and you get immersed more but the expense of getting a colored sound. Get the chopin if you want a tonally correct sounding set and fun at that same time. Get the Fermat if you want more of everything.


Mega5p

-it is one of my S rankers and I rank the mega5p higher than Aful P5. Mega5p is warmer in tonality and isnt as energetic as the Fermat. The techs on Fermat is higher than the Mega5p even if its only a single DD with a PR. Pick Mega5p if you are sensitive to treble. Pick Fermat if you want more of everything.


Planars

- this is an interesting comparison because most people, including me, think that Planars are almost always superior to DDs in terms of techs. However, the Fermat is a different story. I hear more nuance on the Fermat and the Bass performance is miles ahead in terms of texture. Both the Fermat and Planars may have peaks in the treble so they arent a good pick for treble sensitives. But if you have to choose, give Fermat a try.


Dunu Falcon Ultra

- I think both share the same characteristic of being clear sounding. Dunu Falcon Ultra sounds warmer in comparison and is more tonally pleasing because of the organic sound it produces. Although the Bass is more pronounced on the Falcon, the quality of bass goes to Fermat. Pick Falcon ultra if you need a timbrally correct set. Pick Fermat if you want more of everything.




FINAL THOUGHTS


It took me a while to publish my review, mainly because I want the hype to die down and make sure that my thoughts aren't influenced by other people, or I am just being lazy lol.


The EA1000 becomes a gatekeeper at $200 for me.


It's good enough that I cheated my own scoring for the bass haha. I mean Ive heard bone conduction drivers from Mest mkiii. Ive heard fat freq stuff. I adore acoustune DDs for the bass. But the implemenation of the bass on Fermat just hits differently. The Fermat is by no means a basshead set, but the texture it produces makes it easier for me to follow drum patterns.


So, is it really more of everything? I think it's still an understatement. Let me rephrase.


"It's the best for everything at $200"


Happy Holidays.

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.

Hello everyone, and thank you for dropping by. I'm excited to discuss and share my impressions about the EA1000, an in-ear monitor (IEM) that holds a very special place in my heart and ears. Much has been said and shared about the EA1000 already, and it is the flavor of the month for the community. We already have heaps of praise and positive words pouring in from all directions, and love for these IEMs is widespread. I am only going to affirm the same about these iems in my own words.

I've had the pleasure of using these IEMs for the past few weeks. Initially, I was a bit lazy about writing a review, waiting for the right moment and mindset to fully express my thoughts. Interestingly, I wasn't even aware of the existence of the EA1000 until @FiaLm asked me to review it. The Simgot brand name was not something I had encountered frequently until the recent buzz around a couple of IEMs from the brand. I was familiar with the EW200, which, in my opinion, is an outstanding IEM for its price. However, I hadn't come across any other offerings from the brand before. EA1000 is a sweet surprise, for sure.

Once the unit was shipped, I began reading the impressions shared by fellow audiophiles, and the excitement continued to grow. There were good words all around, and I was impressed right from the start. Until a few months ago, I wasn't much into budget IEMs. However, with the OD200 and EA1000, my perspective and focus have shifted. EA1000 has the potential to change someone's views on budget offerings. Are they the best budget IEMs I've heard of? Probably yes, but let's delve into the details, and we'll assess that by the end. I am sure reading this review will help you get a good idea of how these iems sound and what can be expected from them.

Rating Criteria:

I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. I think the fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.

Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.


Technical Details:

Drivers: 10mm dual-magnetic-circuit and dual-cavity structure dynamic
Cable: High-Purity Silver-Plated OFC Litz Structure
Connectors Type: Detachable 0.78mm 2Pin
PRICE: $219.99 USD




Build and fit:

I so much adore the simple yet elegant design of the EA1000. The design on the face plate is a work of art. I am sure everyone has seen the zoomed-in image of those face plates. Doesn't that look adorable? Those metal shells shine brightly and are just exquisite. The shells are small, and the weight seems to be on the heavier side, which is mostly because of the smaller size. Had the size been a bit bigger, the weight would have been better distributed, and they would be lighter. The fit, however, should not be an issue for anyone with small or big ears. For me, it provides a snug fit for my ears without causing any intrusive sensations. It's easy to put these on for longer hours without any fatigue or strain. The nozzle is a bit small and on the wider side. I tried pairing the iems with multiple eartips. Azla Light gives me the best fit, and the shells sit flush inside. I have read a couple of reviews mentioning some fit issues. I think everyone should try these iems with Azla tips; they will find a good fit for sure. Once it fits well and you get a good seal, the bass hits really well. So getting a good fit is of utmost importance for these iems to shine. Also worth mentioning is the non-existence of any pressure buildup whatsoever.

Sound:

Where should I begin while describing the sound quality? These iems are amazingly tuned and highly capable, and I am just blown away by their abilities. The resolution these iems offer is truly exceptional; it's like they have a monster's ability to unravel every fine detail. It's hard to imagine finding such quality sound in this price range and much beyond, and it's even more mind-blowing that a company could achieve this on a budget. They are bright, or, say, treble-focused, but that hot and spicy brightness will not disturb you much. It should not come as a negative aspect of these iems. It does not get to a level to be called overly bright. Honestly, I do not think that's even a thing for these brilliant-sounding iems. The red nozzle is good enough and does bring down the brightness. If you can pair these with a good copper cable and a warmish dap, you are in for a great surprise tour. Let's explore the sound profile in more detail.


Bass:

This is one of the best bass I have heard in a budget- to mid-fi-level iems. I am always on the lookout for good bass, quality over quantity, and these iems possess a very high quality bass. I was in love with the bass since the first time I put them in. It may not be a bass-head level of bass, but I do not think anyone will find them less in quantity. The bass is never underwhelming or overpowering. There is some new tech, and the introduction of a passive radiator makes the bass more fine-tuned and enjoyable. There is a nice feel of reverb and a very lifelike and natural feel to the bass texture. The subbass is quite prominent too. I think these iems have all the goodness of DD bass and add some extra refined bass on top of it. When you listen to some engaging tracks—metal and rock songs—the drums kick with good impact. On less engaging and relaxed tracks, the bass is just right, seamlessly blending with the higher frequencies and allowing you to focus on other aspects of the music. The controlled nature of the bass in these iems truly sets them apart from the crowd.

Mids:

The mids on these iems are just wonderful. They are a bit forward, which aligns with my preference. The tonal weight is quite good, which adds a nice character and body to the mid-range. Thanks to the brilliant resolution on these iems, every tiny detail is brought forward in the most engaging way. The clean and crisp mid-range is the soul of the show for me. This goodness in mids provides clarity and accuracy, allowing vocals and instruments to shine with a natural and lifelike timbre. There is a very nice richness in the way string instruments sound. Overall, there is an emotionally engaging sound that is more romantic than musical. The upper mids have a bit of higher energy but do not get shouty at all. Vocals on these iems must be talked about. There is a sense of warmth and intimacy in the vocals, irrespective of the genres you listen to. Both male and female vocals are full of soul, with no thinness or unwanted heaviness whatsoever. Every bit of raw power and delicate nuance are conveyed properly. Needless to say, this is again an amazing achievement. The mids are always a special sauce for an iem and I am glad to affirm that this sauce is so exceptionally flavorful on the EA1000.


Treble:

I have a bit of sensitivity to treble, but with these iems, I do not find any fatiguing treble. If someone finds the brightness troublesome, they may have to put in some effort to tame the treble, but for me, I am pretty okay with the red nozzle and a decent copper cable. I think my dap, LPGT, which is a bit on the warmer side, also helps a bit. On more reference sources, it may get disturbing for some. But I am sure we can take some pain for our little champion to shine and show it's full potential. Once the treble is sorted and pleasant, it is evidently of very high quality—balanced, detailed, airy, and expansive. I think this treble is likeable for all genres—jazz, rock, metal, pop, anything. There is a very decent level of transparency and clarity in the treble region. The decay of cymbals, the strumming of the guitar, the extension of high-pitched vocals—everything is captured quite beautifully.


Technicalities:

As evident to this point, these sets are highly technical. I am still unsure how these IEMs are so good at resolving details. In terms of resolution, I think they can give a good fight to most of the iems below the 500 USD mark. The soundstage is quite good, though a bit on the intimate side. Still, there is good depth and height. The imaging on these is quite top-notch and accurate. The positioning of instruments can easily be determined; they have such precision. Adding to all this is quite good instrument separation, which does good justice to busy tracks. The layering of instruments unfolds quite nicely.


Cable Pairing:

The cable which comes with these iems are simply nice. This cable is a silver-plated OFC Litz cable. It does lack a 4.4mm termination which many would find bothering. Thankfully most of us have spare cables which come to rescue. But the omission of a 4.4mm termination is really sad because I really like the quality and finish of these cables. They are shiny, sturdy and lovely to look at. The iems sound as good as on this cable as on other cables. Though I do not have any complaints at all with the default resoultion of these iems, they do resolves quite better when given a premium cable. You can imagine how good this thing can be. I have an Effect Audio prototype cable which is sort of premium quality. The bass impact is better and the treble gets bit of taming. There is bit of widening in the soundstage and there is an extra separation in the instruments. The clarity becomes a lot better. All these things make the iems sound quite better. The bass improvement makes it a lot more likeable. That is what some good cables do to the iems. The few areas of improvement which these iems need are nearly sorted by using a good quality cable.


Source Pairing:

These iems benefit the most from a warm source. A neutral or bright source can make the treble a bit spicier, making it difficult for treble-sensitive people. I have a very decent pairing with my LPGT and A&K SP3000. Because of it's massive sound-stage and clarity in it's sound, SP3k takes the EA1000 to another level. I think these iems perform to their full potential on the SP3K. Both of these daps help with better bass delivery. My preference leans towards the SP3k. On the other source, Earmen Angel, due to the better power supplied to the iems, there are again some enhancements in soundstage and dynamics. However, the resolution takes a back seat as the Angel is not so highly resolving dac.



Conclusion:

To be honest, I wanted to spend a significant amount of time with these iems before writing down my thoughts. In a blind test of these IEMs, I am confident that people wouldn't come close to guessing their price. They are so incredibly impressive. Simgot has pushed the boundary to an unprecedented level, stepping up its game. These IEMs set a benchmark and are undoubtedly the best in the $200 USD range. In terms of abilities and technicalities, they can give a good fight to IEMs that are double or triple their price. With some extra effort in cable rolling and perfect source matching, they reach unbelievable levels. If Simgot EA1000 were sold under the brand name Campfire Audio or 64Audio, the iems would have been priced at more than 1000 USD. I am sure no one will disagree with this. I think setting a price of 200 USD is just too absurd. Other brands in market should learn from Simgot about how to deliver a high-end sound within budget.

Not only are they aesthetically pleasing, but their sound is also beautiful. They are so addictive that you'll find yourself reaching for them regularly. It's not your typical single dynamic driver IEM; it offers much more—class-leading technicalities, amazing tuning, and unbelievable resolution. I adore everything about these IEMs to the extent that I no longer feel the urge to spend a lot on IEMs these days. I know some budget iems can be unimaginably good. Paired with the OD200, it stands as my IEM of the year. I am genuinely in love with these IEMs, and they hold a special place in my heart. I hope they bring you the same joy. Highly recommended. 5/5.

Introduction and Packaging Impression​

Simgot EA1000 "Fermat" ($219) is a single 10mm dynamic driver IEM with a 6mm passive radiator. I've been quite intriqued by Simgot's naming scheme, with some interesting write-up inside the box about the famous mathematical problem "Fermat's Last Theorem". For those who are not familiar with it, it is one of the most difficult mathematical problem ever solved in human history with the largest number of unsuccessful proofs, and Simgot is drawing parallels between the humanity's effort to solve this problem with their work in designing EA1000 as an homage to the eventual proof of this theorem in 1995. Quite a lofty idea here, but Simgot indeed is one of the first IEM manufacturers who popularized passive radiator in IEM design with the EA2000.

What is a passive radiator?
This is a more commonly used technology in full-sized speakers, it is basically a speaker unit without voice coils or magnet that will resonate with the main speaker driver at certain frequency. It is usually used to resonate with the bass frequencies in a non-vented (non-ported) design.



However, if you see the shell of the EA1000, there seems to be a vent as well as the big hole for the passive radiator, making it pretty puzzling. Also, as I was researching about this IEM (and also its big brother, the EA2000), there are a few skeptical people who expressed doubts whether this PR is just a gimmick and basically useless due to the lack of full seal and the fact that IEM is being used so close to your ears, it would not matter so much. However, as I listened to EA1000, I would say that there is definitely some merit to the passive radiator here. I will get into more details in sound impression.



The packaging feels premium, with an excellent carrying case. The cable is very pretty with a very nice finish, however only available in 3.5mm. Given the power demands on this IEM, I really would have liked it if it is available in 4.4mm. There are 6 pairs of eartips, 2 pairs of each size, so you will have some spare in case you lose some. There are also 2 pairs of alternative tuning nozzles: one pair golden copper, one pair silver steel with black ring. The default installed filer is silver steel with red ring.

Sound Impression​

Sources: SMSL H300+D300 stack, Fiio Q15, ifi Gryphon, Hiby FC6, Topping G5, L&P W2-131
Setup: Stock L size eartips, stock cable (3.5mm), Yongse SCC SPC 2-core cable (4.4mm)
Music Sources: Local FLAC (redbook/hi-res), Tidal Masters, Apple Music Lossless

The IEM has undergone a 30-hour burn-in at a medium volume for prior to the review.

Listening impression is a very subjective experience depending on individual ear shape, choice of eartips, music library, and personal preferences, so your experience may vary.

First, I have to address the tuning nozzles. This is my brief impressions of each of them:

• Silver with red ring (default): smoothest upper mids with good amount details
• Silver with black ring: sparklier than the default nozzle, best treble extensions among the three and the most resolving, but can be shouty
• Gold: quite shouty, but offers the most distinctive texture in upper mids; personally not my favourite

I personally prefer the silver with black ring nozzle, but I do acknowledge that I'm quite tolerant towards some shoutiness. I believe the default nozzle will be have the widest appeal. Also, I think most people will go with the default settings at first, so the rest of the review with the default configuration.

So, the big question is: does passive radiator (PR) make a difference?
I would say it does. Let me explain: in a hybrid design, the tuner can individually adjust individual frequency ranges to match the target sound independently, but in single-driver design, any changes will often affect the whole frequency range. PR allows the tuner to specifically target just the bass frequencies more accurately. Comparing the EA1000 to its PR-less sibling, the EA500, you can tell that in EA500, the tone and texture is uniform across the frequency range, but in EA1000, the bass region is noticeably more resonant and has more reverberation than the rest of the frequency range, something that's unusual in a single-driver configuration.

I find that EA1000 is very technical in the upper mids and treble with a decent amount of air. The overall tuning can be described as neutral-bright, but there is a slight midbass emphasis to add that "thickness". It seems that the PR does something to the bass perception of the IEM, since on graph, it should be quite similar to the EA500, but I feel more rumble with EA1000.

Bass​

I would say that EA1000 has one of the best bass texture and timbre regardless of the price range. The low notes are rumbly and deep, with long enough decay to get that smooth bass sensation. The only thing that I sometimes find missing is the bass amount, which I think separates this from TOTL-class IEMs' bass performance. I attempted to rectify the bass quantity by adding a modest bass boost with PEQ at around 250 Hz and below or by using ifi's XBass, but I noticed some audible distortion. That said, in majority of my tracks, I find the bass quantity and quality to be sufficient. I think EA1000's bass is definitely the highlight of this IEM.

Midrange​

The midrange is very well done at this price point with a lot of details and natural timbre. There is a slight concern of shoutiness in certain tracks, but nothing that some tip rolling can't fix if it really bothers you. The vocals are neither too forward nor too recessed, and I find both male and female vocals are equally well-reproduced with great texture and note weight. I think the overall midrange impression is very positive for me.

Treble​

I find the treble to be excellent. I think the presence of the passive radiator allows Simgot to put in a very fast DD with a very good detail retrieval without making the bass too tight. This makes the treble performance also equally a highlight and impressive for the price range. The treble does seem to perform more similarly to a BA, but without the BA timbre. The treble texture is also relatively smooth without any harshness, and the treble extension is excellent. I think EA1000 can easily go toe-to-toe or beat hybrid IEMs at its price range.

Technicalities​

Soundstage and resolution are the two standout technicalities of EA1000. I find EA1000 to be grand sounding, some sort of opera house effect to a certain extent. EA1000 does have that lower frequencies reverberations that keeps the staging natural and enhances the sense of spatial awareness. The resolution, as I mentioned earlier, is excellent due to the really agile driver. Layering and imaging also benefit a lot from the expansive soundstage and excellent detail retrieval. For the price point, nothing to complain about.

Driving Requirements & Pairing Suggestion​

While EA1000 is relatively easy to be driven, it does scale a lot with power, especially in the bass department. Some amps with tighter bass control like the H300 and L&P W2-131 have noticeably better bass rumble and texture. I would also avoid pairing it with brighter sources like Topping G5, which may exarcebate the potential shoutiness.

Select Comparisons​

Simgot EA500 ($79):
People with EA500 would be more likely to look into EA1000 as potential upgrade. I would say, EA1000 is indeed an upgrade from EA500 in all aspects; if you want more from EA500, then EA1000 is the answer. Tonality are very close, but timbral quality is much better with EA1000. However, I find that EA500 to be the less fussy one in amp pairing, so depending on your existing setup and upgrade budget, you might want to plan well if you think of upgrading to EA1000 from EA500.

Tangzu x HBB Wu Zetian Heyday Edition ($199):
I mentioned in my previous review that WZT Heyday is my $200 gatekeeper personally. Given that EA1000 is slightly above $200, I think the status quo is undisturbed, but if I was asked to buy one right now, I'd spend the extra $20 and get the EA1000. The level of technicalities are similar, but tone and timbre of EA1000 is way more superior. The rumble of the bass and vocal performance is also much better with the EA1000, I find that the performance difference is much larger than the price difference.

Conclusion and Final Thoughts​

I think Simgot did hit the homerun with EA1000 this time. I personally did not find EA500 to be that special (in fact, I prefer the EW200 instead), but EA1000 is really offering something special. The PR technology certainly works in this implementation to my ears, and it's hard to find what not to like about this IEM. I would easily recommend this to anyone even for blind buy. Easy 5 stars from me.

Introduction
Simgot is one of a few Chi-fi companies that managed to capture the heart (or the ears) of many audiophiles in the recent year. With their capable, high quality, dynamic driver along with their competitive pricing, Simgot just keep impressed us from their cheap entry level option like the EW200, EA500 to this iems right here, the EA1000.

The Simgot EA1000 house a proprietary purple-gold diaphgram DD along with a very special Passive Radiator, which was a trickle down tech from their older brother, the EA2000. It was said to improved the bass texture and add many subtle nuances which in turn improves the whole listening experience. In this review, i'll dive into what makes this iem special.

The EA1000 has a MSRP of 220$.

*Disclaimer: This iem was a tour unit that Simgot provided for me and my audio group in exchange for our reviews and impressions. I did not pay for this iem. I would like to thank Simgot for giving me this oppotunity.

Packaging

The box of the EA1000 was not as big as i thought. It was smaller than i thought. Here are some pictures of the inside of the box.


Inside the box as you can see, Simgot provided us with: The iem itself, a silver plated copper cable in 3.5mm termination, 3 pairs of tips, 2 pairs of exchangeable nozzles, a few silicone rings of the nozzles themselves

Design/Build quality/Comfort

Similar to the EA500, the EA1000 also has a stainless steel housing with a glossy surface. This makes the iem very prone to scratches and fingerprints. The faceplate on the other hand was a piece of clear glass with some intricate design pattern. Different from the EA500, it was harder to spot the scratches and stuff with the EA1000, which will makes it more appealing. The iem feels very sturdy on hands.


Above are the pictures that shows the outside of the Passive Radiator (PR) and a glimpse of the Dynamic Driver.

The nozzles themselves are detachable. This allows you to change between the 3 pairs of nozzle to be more suitable for your preference.


The cable is a 2-cores OFC silver plated cable. It feels very high quality. It's soft, thick yet not too heavy and not tangly.

Comfort wise, i can wear the EA1000 for many hours straight with no discomfort or hotspot. Isolation is really good with very little sound leakage.

Sound impression:

*Test gear:
- Source: Poco F3, Dell laptop
- DAC/amp: Chord Mojo + Cypherlabs Duet, Ibasso DC04 Pro, E1DA 9038D
- Eartips: Spinfit W1, Divinus Velvet
- Cable: Stock

Tonality: Harman-ish, neutral bright

During my test, i find the EA1000 to be very to drive. Even using only the DC04 Pro has brought me a very satisfied result with the EA1000. The E1DA 9038D on the other hand is too bright, too analytical which makes it the worst pairing with the EA1000. Chord Mojo was like a match made in heaven with the EA1000, since its slight warm, colored tonality is very suitable for the neutral bright, slightly analytical tune of the EA1000. The DC04 Pro and Mojo is what i mainly used during my review.

In this sound impression, i’ll be mainly using the red nozzle as i don’t like the foam inside the black nozzle, which affects the bass texture compared to the red. The black nozzle also sounds a bit brighter. The yellow nozzle on the other hand, it sounds a bit... rougher in its presentation. It also sounds a touch shoutier, more vocal forward and not as wide, which i dont like as much compared to the red.

Bass: 8.5/10

Subbass is gently roll-off, shifting the focus more towards the midbass. The EA1000 overall has a really fast, punchy and tight bass texture. You can actually feel the quality of the driver themselves, judging from their attack, release, sustain and decay. It’s near planar level of speed if i dare say so myself. Together with the PR, the bass just have this very addicting sense of body and layering, but it’s not at the level of real life speaker with a “real” PR yet. EA1000 can easily keep up with those fast pace drum and guitar session without feeling it’s dragging behind or feeling blurry between each notes/hits.

Mids: 8/10

The midrange of the EA1000 is also really good. Lush...is not the word i’d use to describe it. I mean yes, it does have a hint of warm since there are very light bass bleed, but because the bass quality was done so well, it doesn’t feel muddy or bloated. Instead, i’d say the midrange here is clean, clear, bright, hint shouty (very lightly) and definitely not sibilant nor harsh. However, it’s not the smoothest midrange out there.

Simgot really rides on the borderline of making this really shouty with the usual pinna boost like many other Harman-ish iem out there. The EA1000 does lean more towards the upper frequency, where they focus on that vibrancy or high notes one may associate with female vocal. Male vocal sounds fine, more than fine, but it doesn’t have that wow factor or the usual weight of some singer like Frank Sinatra or Michael Bubble

Instruments like violin, flute sounds emotional and lively; piano has a very clear, well definite notes that lean more towards the bright, cleaner side.

Treble: 8/10

Treble is also done well. It’s highly refined, well extended, not overly boosted nor too airy. The being said, they are on brighter side. Cymbal strikes and hihats have good shimmering to it without being too forward and take the spotlight from the bass and midrange. The boosted upper mids and presence region make these instruments sounds sharper, almost metallic but not sounding too harsh. This part here is what affects the most to the overall balance of the EA1000, preventing many high volume listener to fully enjoy the iem without it modded.

Out of all iems in my everyday-carry collection (not that i have many to begin with), it’s sufficient to say the EA1000 is top3 in terms of treble extension and the pure detail it brings.

The treble maybe fatiguing at times, which is why i said i prefered the neutral DC04 Pro or the colored, warmer Chord Mojo over the brighter E1DA 9038D most of the time.

Tech: 8.5/10

While the EA1000 didn’t exactly wow me with its soundstage size (All 3 planes are above average), it does impress me with the imaging, crisp layering capability as well as its resolution.

The highly controlled bass together with the good extended treble, as well as the well layered mids just seemingly contribute to this high level of technicalities.

Timbre is also good, although the EA1000 leaning more towards the analytical, monitor-like timbre instead of a more warm, velvety timbre on a more relaxed sets.

Using “Bubbles” and “Swashers” from Yosi Horikawa, the EA1000 does showcase a very capable dynamic rendering as well as stage reproduction.


Comparison:

Vs Simgot EA500

It’s been quite a while since i last listening to the EA500, but from my memory, the EA1000 has solved the two things that’s bugging me the most with the EA500: Its metallic timbre and the tonal balance. The EA500 sounds brighter and way brighter in its stock form compared to the EA1000. The EA1000, along with its passive radiator, has higher bass quantity which overall makes it sounds way more balance and enjoyable compared to the EA500. Heck, i’d argue that just solving that metallic timbre alone has made this EA1000 a worth-while upgrade from the EA500. Technicality wise, the EA1000 is better than the EA500 in almost every way, in terms of resolution, bass texture, treble sparkliness, the soundstage,...


Vs Tanchjim Oxygen

The Oxygen has a special place in my heart. It was the God Father to the Olina SE - the iem that truly brought me into the audiophile world. I’ve been using this iem the longest in my collection.

Compared to the EA1000, the Oxygen has an overall warmer, less V, more U type of tuning, vocals sound a bit thinner and sounds technically inferior compared to EA1000 in detail retrieval and imaging. Soundstage wise, the Oxygen has a more intimate staging with inferior separation. Bass texture on the Oxygen sounds notably looser, whereas the EA1000 sounds tighter with faster, snappier attacks and transients. The uppermids and treble of Oxygen sounds noticibly less “hot” compared to the EA1000.

That being said, the overall balance of the tuning of the Oxygen along with its more natural timbre still makes it a notable iem in 2024, even if it was released almost 6 years ago. The EA1000 did not completely replace the Oxygen from my rotation, as the Oxygen is still my preferable option when i want to laid back and just enjoy some good ol’ music. The small housing of the Oxygen just make it seems like it’s floating in my ears.

The Oxygen is also harder to drive compared to the EA1000.

Since my version is the old, 2018 version that hasn’t gone through with the driver change, there’s no need to beat yourself and just get the EA1000 instead. If you’re a detail and technical chaser, EA1000 is a worthy upgrade. You’d be more than satisfied with it.


Vs BQEYZ Wind

On the graph, both of these may look similar especially the bass and lower mids, but in real life listening, these two sounds very different.

The Wind has an overall warm tonality with a hint of darker treble. While the EA1000 has a tighter, faster bass texture; the Wind has a bit slower, more mellow texture bass. The Wind just feel like it’s dragging the end of its bass notes, more bass extension if you will, which makes the layering a bit blurry. Both of these iems have a very clear and forward midrange, but i’d say male vocals have more weight to it on the Wind. Treble wise, the EA1000 sounds brighter, airier, more refined compared to the Wind.

Micro details and imaging, the EA1000 takes the win; whereas macro details, the Wind wins just slightly. Soundstage wise, The Winds has a more 3d soundstage with the help of the open faceplate and the BC.

The EA1000 takes the win to my taste, purely because of the bass. The EA1000 just sounds more effortless compared to the Wind. Not to mention, it’s highly depend on your fit in order to feel that BC.

I’m pretty sure my impression regarding the BQEYZ Wind is legit as i’ve use my shortest, widest bore for the Wind in order for it to contact my ears, so which i can “feel” the bone conduction. Even if i press the Wind into my ears, my impression did not change, so there’s that.

Vs Hidiz MP145


The MP145 maybe a planar, but since it’s one of the best planar in the market at the moment in the 200$ bracket, as well as the fact that its timbre is very DD like, i think this is a worthy comparison. Many people also ask me which one they should pick between the 2, so here’s what i think.

Right of the bat, if you have smaller ears, skip the MP145. The MP145 shell is huge, along with its changable screws on the nozzle which increase its width to be around 7mm! That would affect the fit of quite many people.

Tonality wise, the MP145 has a bassier and warmer type of tuning

Both of these iem has a very fast bass, but the MP145 sounds a bit deeper and more rumbly. Together with the less emphasised uppermids, the bass sounds way more apparent and hits you harder. This also let you listen to the MP145 to a higher volume.

Vocal aren’t exactly the strongest point of the MP145, especially when it goes against the clearer and more vocal-focused EA1000. The bass of the MP145 just adds that additional lushness and weight into the midrange. It’s also standout the most in the spectrum of MP145. The MP145 sounds smooth, lusher, non-shouty and definitely less agressive than the EA1000

Treble wise, both iems are very airy, but they have a slight different in presentation. With the song “Silhouette” by Kana-Boon, on the MP145 has more “zing” to the cymbal strikes and hihats, where as the EA1000 sounds sharper, more rough around the edges. Both of these sound natural though.

Soundstage wise, the MP145 sounds a bit wider with just as impressive depth and height. Imaging wise, both of these are on a similar level to my ears. The EA1000 beats the MP145 in overall detail retrieval.

Depending on the preference, one may like more than another. EA1000 may sounds shoutier and too forward for their taste. Where as the MP145 may sounds too bass heavy with not enough uppermids bite. Personally, i like both. I enjoy EA1000 in a more clinical listening session whereas i would enjoy MP145 in a more relaxing session. You will win with either of this iem

The MP145 is also harder to drive.

Conclusion:

Simgot has set a new benchmark on what iem in the 200$-300$ price range should bring. Not just the sound itself, but the overall package and especially its changable nozzles that allow the users to fine tune the iem to their liking. They really knock it out of the park with the EA1000. I’m looking forward to see what they have to offer in the future.

I highly recommend this iem.

When i got the chance to review these IEM, first thougth was: they were made with care in mind. The packaging is beautiful and has some neat folding, showing that SIMGOT wanted tohighlight the care they put in creating them.
There's multi kilobuck IEMs that have worse packaging than this, thus it's a really good starting point. Since it has multiple eartips AND metal filters, it's all arranged so you can keep your eartips in neat storage and your metal filters all safely screwed in a metal support. Might have saved them some money putting it all in plastic bags and call it a day, but instead this approach shows they want to respect the customer that purchases the EA1000 and they themselves think that this product deserve a nice packaging.

Enough with the aesthetics, that ARE commendable, but instead let's talk sound.

Fair warning: i'm using them together with the LC7High Balanced Cable, that i will review separately, because i always think going balanced is the best way to enjoy audio gear.

The instantanenous, immediate impact, before all the reasoning about the FR and technicalities, was soundstage. Using chesky records music, that is quite famous for their realistic positioning, i felt the most sourround experience with an IEM i have ever experienced. Blessing 2, Audeze Euclid....and then out of the blue the EA1000 surpassed them all in soundstage. That itself is a big surprise!

This IEM has 3 swappable pairs of metal filters that can be screwed in. Unscrewing them lets you access the inner parts of the resonance chamber. On this point, i am going to tell something that i feel is fundamental: I NEED TO BE ABLE TO GIVE MAINTENANCE TO HIGH END GEAR. What does it mean? That while with other IEM you need to be careful not to dirty them and if anything gets inside the metal filter and you have any dirt pushed in, good luck taking it out. You need something with powerful suction to HOPE to clean them. WIth this pair of IEM just unscrew them, access them from the inside, and you can clean it to your heart's content.
The fact that a IEM at this price range manages to be able to do this while kilobuck IEM are just condemned if get dirty is reason enough to praise simgot and shame other brands for not thinking such a simple solution was almost mandatory for high end gear. Even more so if you ever plan on selling kilobuck gear. While this is non-sound related, i feel like we need to keep repairability and serviceability of audio gear in high priority, almost on par with sound quality, otherwise we'll have useless throwaway multikilobuck gear and that's unacceptable.

To make it an interesting review, i'll pit it against my Euclid because, of the other IEM i have, it would be almost "too easy" to just declare them the winners. This to me should already be a testament to how good these IEM are.

Black Filter:
Welcome to the jungle: Powerful and controlled bass, pleasant voice, highs are kept under control.
Body Company: Bass are plentyful, mixed in with the highs it turns in a very enveloping sound, detailed and musical. It mixes very well the whole FR. Instrument separation could be improved, but that would push it into kilobuck territory (more than it already does). Compared to the Euclid, they are a step under them in instrument separation and raw detail. But the tonality is great!
It's only a paper Moon: Great soundstage, it seems the low end of properly mastered songs enjoy an incredible wide soundstage compared to its price range, going to rival the euclid. The overall raw detail is lesser but soundstage and musicality make them shine!
Beethoven 5th Simphony Op.67: Karajan sure knows how to bring in the thunder, and i'm happy to say that the EA1000 make for GREAT listening. Again tonality is top notch, instrument separation is good and oen of the best thing is soundstage.

If i were to sum up the technhicality of these IEM is like you can precisely focus on the sound, with a great soundstage, but probably some small limitations in the drives don't let you "see" perfectly the demarcation line between the sources. It might be considered both a flaw AND actual skill. That might sound confusing but bear with me: 100% definition of sound is...not really paramount. Don't think i don't enjoy that, hell i bought the LCD5 for their uber-detail. To have a hint of merging between the various sources isn't outright bad, just that it's not some kind of magical IEM that can outdo kilobucks...yet.
But IF they improve on this, kilobuck territory would be fair game for simgot. Meaning they could make lots of "top fi" IEM become suddenly price-mogged by simgot.

Red Filter:
A little less bass, increased highs. I don't think it's better this way.

Gold Filter:
Feels a little more visceral bass-wise than standard nozzle. I think it contends for the best tuning together with the standard one. I will update the review if i feel to be more in depth about them, but rule of thumb i use them more than the standard one.

Conclusions:

Having had the chance to try them, side by side by my only higher end IEMs, i would say that the EA1000 are simgot continuos rise toward the ranks of top-fi gear. Being able to do so on a budged while NOT skimping on packaging and serviceability makes me VERY hopeful of the brand's future. If the pattern holds we might end up seeing a 1k IEM from them that would make the top-fi and summit-fi market VERY nervous.
It's well extended in FR, basses are impactful and detailed, highs are kept under control without sounding shrilly or screechy, mids are kept clear and defined.
Also, do yourself a favour and use a balanced cable on them, they will thank you and you'll enjoy them better.

The New SIMGOT EA1000 Flagship IEM



Introduction:
You’ll have to excuse this review, that while informative, it is incredibly long. It’s just when IEMs are this good for the money and so groundbreaking in what they offer, there is no choice but to talk a lot about them. In fact even if the EA1000 was 1/4 less as good it would still get the full 5 stars from me. Yep.

SIMGOT as a company is on a roll. The two prior major releases which have amazed the community have been the EA500 and the EW200. I will get into both of them in a few.

https://www.head-fi.org/showcase/simgot-em2r-roltion.26084/reviews#review-29526

Even though SIMGOT has been around for a while, they have never gained the popularity they have now, and it seems they are going from strength to more strength? Back in early November of 2022 I reviewed my first SIMGOT, the Roltion EM2R and I only gave it 3 stars. The issue for me was that it didn’t have enough note-weight. But more than that, the IEMs SIMGOT puts out now almost don’t even seem like they are from the same company? Improved ergonomics in fit is one reason….still with the EA1000 being 11 grams each, the sheer weight makes you wonder? The past EM2R was almost too small and too low weight. But this EA1000 is really perfect, though maybe getting better ergonomics with the supplied cable, due to the included ear-hooks?

Meaning as far as fit and comfort goes, the correct cable ergonomic movements, the weight and just how they sit inside your ear.......plus the nozzle length……it is actually surprising to a jaded reviewer like myself just how well these fit and stay in place? If you look there are a series of air-vents which inhabit the rear (ear-facing) area? Three vents and one giant one, something about this device being a passive radiator? There is a gold screen for it, yet all three vents never get blocked.........somehow?

The EA1000 Technology:

1) SDPGD technology
This added process uses Sputter Deposition to create a more rigid and lightweight diaphragm. In terminology, the SD stands for Sputter Deposition, and the PGD stands for Purple Gold Diaphragm.

2) DMDC Dynamic Driver
This is a dual chamber created for the driver.

3) 1DD + 1PR
This is a combination of an active 10mm driver with a 6mm passive radiator

4) The EA1000 changeable nozzle technology
Here three nozzles are included as a way to generate three specific tuning curve directions, using both stainless steel and brass materials.

SIMGOT EA1000 first impressions:
For me the addition of DD and Passive Radiator seems most important, as there really is this natural ambiance to the bass which stands out different than any IEM in this price category? There are truly added dimensions of texture and ambiance to the bass quality? They say this is the direct result of increased air-flow and that is really what it sounds like, you can hear this technology in action? For me I listened first then read about the technology later, and this was part of my first impressions, noticing how the bass was effortless and agile? But obviously there needs to be special attention to the mids and highs, yet on first listening both the mids offered a nice smooth midrange and treble offered great itemization of imaging outwards into the stage. Though prior to burn-in I noted a slight lack of low-end punch that kept the EA1000 as a recommendation to a rock or EDM listener. Though the most rewarding sentence in this introduction is the EA1000 completely changed upon 130 hours of burn-in. While it basically still had its personality, except added smoothness took place, and added bass authority which allowed for a fantastic IEM inclusion with rock and EDM. To try and put this into perspective, the EA1000 was so good right-off-the-bat........that I was still fully enamored with its abilities, and continued to find stuff it played well. But after 130 hours of burn-in really it was way more well rounded and played all genres.


The filter system:
It’s best that I briefly go over what SIMGOT is attempting to do with this new filter system. Graphic representation of what each filter does is represented on the box.

1) The new Golden SIMGOT target (brass filter system)
2) The way they came with the red rubber rings. The 2019 Harman Target, my favorite no doubt.
3) The black ring filter, SIMGOT Classic target.



I listened first to try and get a handle as to what they are up-to with the filter system. You can’t help but note the black foam on the underside of both the black and red ring filters, with the Golden brass nozzle having only a white sticker with a small hole in the center? The Golden curve is slightly more clean, less thick.

Comparisons:
These comparisons are a way to understand an IEM due to contrasts of abilities and tone. Of the eight comparisons provided here four of them are previous SIMGOT products. I added the four SIMGOT products as a gateway to help in understanding the EA1000, especially if you already had made a SIMGOT purchase in the past. Also I added them to try and document just how far SIMGOT has progressed with the new EA1000 too. The other four products are used to kind of delineate the differences and abilities by direct side-by-side comparisons. All tests with Sony WM1A with MrWalkman’s firmware, my typical wide-bore silicone ear-tips and White Whale Cable in 4.4mm. I in no way want to be-little the included cable because it’s really nice, except it comes only as 3.5mm, yet I often referred back to the included cable, if not only to make sure I was not missing anything in 3.5mm.



Test 1:
I simply chose the IMR BC 2023 and 7Hz Legato test subjects as I thought the contrasting bass (to the EA1000) would be fun? Both the IMR BC 2023 and 7Hz Legato are considered bass cannons, and while that is true there is still a wonderful balance that the IMR BC 2023 is renowned for. Such a forward IMR midrange that has many simply smitten with the produced frequency outcome, including myself.

IMR BC 2023: $369.00
One 6mm ADLC (amorphous diamond like carbon) driver and one (size undocumented) ADLC driver:
Here we are reminded that the IMR BC 2023 isn’t really that much of a Bass Cannon after all? Its name is maybe a marketing tool? And while yes, it does designate the BC 2023 into a curiosity of listening, I can’t help but wonder if true Bass Cannon listeners will not be let down? After taking some time off from the BC 2023 what really hits me first is the warm midrange it holds, that and the a wonderful separation contained. Such imaging of elements out into the stage really, maybe due to it being 2 DDs, come across even more technical than the EA1000 hoped for. Way more money than our EA1000 and rightly so, as this style of replay has its own charm, yet probably when it comes down to it the EA1000 has a more (maybe) together timbre in the end, not as separated of imaging. The EA1000 has a slightly cohesive and natural tone, despite being overall brighter and more juiced-out up-top. Still in our testing today there is only one Bass Canon and that’s the 7Hz Legato! Still what seems like a less dampened IMR response goes ahead to provide slightly more volume at the same level, inside that volume we are gifted with a bigger stage and further-out larger imaging of elements, better crafted inside that stage. Where the EA1000 is more straightforward, the IMR is kind-of a character, in holding a darker wider positioning which promotes less brightness up-top, but creates a smoother treble all its own.

7Hz Legato: $109.00
Large 12mm Dynamic Driver with Multi-Layer Composite Diaphragm and 6mm Micro Dynamic Driver With Composite Diaphragm:

Bass focused is really the word on the street here. Even with my mid-centric WM1A and wide-bore silicone ear-tips, I can’t help but realize that this is some of the most bass I’ve ever heard from an IEM. Though if you note closely you can still hear the top-end treble balance, as they had to do something to make this style of replay digestible. In essence this treble is the magic that helps this very unorthodox tune seem to work out. Still for this replay to be enjoyed there needs to be a subtle acclimation period as typically the L shape tone will come as a surprise from any style of playback you’re accustomed to. Where here if there was any proof as to the deep bass emphasis contained deep down into the song structure, it is truly there……..all of it! Though in contrast to the EA1000 we also get some extra baggage in the form of bass bleed into the midrange. Yet to top the Legato off, or yet to bottom the Legato off……….there is added bass emphasis to somehow add pace on-top of what would be considered a deep and thoroughly displayed rendition of bass. If anything at all, it shows how our EA1000 can arrive at better well roundedness in daily use. Also we come to realize that some music simply doesn’t go so low in range, that there are albums and even whole genres of music that don’t have a need for such extremes in Hz playback. Yet there is a time and a place for what the 7Hz Legato does. It actually may end up complementary (to the EA1000) for many listeners, being the Legato playback is special and one-of-a-kind. But in contrast......the EA1000 is way, way more mid forward offering a faster yet still authoritative bass response……added to that due to the bass balance differences from the Legato, a treble that’s there as well as the boost that’s offered with the EA1000 at 14kHz.......which ends up taking the whole signature into more clarity and imaging expansion.



Test 2:
The Kiwi ears Orchestra Lite: $249.00
8 Custom BAs:
The Kiwi ears offer lean and faster itemization of sonic elements. Bass is way less visceral and slightly set back in comparison to the EA1000. Even though tuned slightly the same, the Lite’s midrange here shows a more metallic tone. Where our money here is in more EA1000 note density, more note weight from the EA1000. In fact it’s the overall weight of the signature which goes to make the EA1000 special, more special than I thought after this test was complete?

The Kiwi ears Quintet: $219.00
1 Diamond-Like Carbon 10mm (DLC) dynamic driver
2 balanced armature (BA) drivers
1 planar magnetic driver
1 piezoelectric (PZT) bone conduction driver

Bigger separation into the stage, as this is our first Hybrid today. Yep, all those different driver methodologies doing something. Just amazingly separated imaging here with the Quintet. Also the low-end is kicking its rightfully so authority! The Quintet replay today is simply amazing here? The way each element is in its own area of the stage, like each element is free to act how it wants? The EA1000 has slightly better bass, and interestingly enough bigger imaging into the stage, with more weight and size than the Quintet? This was one amazing side-by-side, as the EA1000 can keep-up in its own way with the Hybrid of the Quintet. Bigger size of midrange out into the sides, where the Quintet is grand, but lacking in note density and girth? There is a slightly faster attack and decay that comes with the Quintets top-end, yet the EA1000 has better note decay.



Test 3:
SIMGOT EA500: $79.00
10mm Dynamic Driver:
The moment of truth. While at this early point in time it’s safe to say the EA500 is more popular, as it has had more of a chance to become popular. Where the issues for some were they just didn’t find the signature as accessible as others. That once again just proves how subjective this whole business is. Where I found the bass fine, graph readers saw issues, and some simply found the midrange to be on the hot side. Where probably much of that came from (again) the lack of lows for some listeners to balance out the highs? Still in my book the EA500 can do no wrong, in fact I hear bass detail in the bass department. Also I feel the EA500 is one of the single best imaging IEMs for the money, just the technicalities it does on a regular basis. Though-out this year that fact has been confirmed and reconfirmed as the SIMGOT EA500 has been re-introduced into side-by-side tests, over and over again. Such is life when a major value is tried again and again to see if it still holds value in relation to other competitors. The first thing you notice is how the bass of the EA1000 has its own area of life, there is more of it, but also better quality as it’s defined and tailored to be dressed more for success. Combine that with a more filled out midrange of better imaging and detail, and finally the treble gets imaged further out into resolution. Hands down across the board the EA1000 is better at everything…..and even more so when they are tested back-to-back.


SIMGOT EA500 with filter nozzle system:



SIMGOT EW200: $39.99
10mm Dynamic Driver:
For many the EW200 was a success over the EA500. SIMGOT shifted gears from a EA500 2016 Harman Target to the 2019 EW200 Harman Target. For many the EW200 showcased just what 2023 was about as far as IEM value. And I have to agree, that single handedly the EW200 showed the world how much IEM was obtainable for under $40.00. For those wanting the extra low-end SIMGOT went ahead and added the goods, making many happy in the end. And that’s not to say the EW200 is any kind of Basshead IEM, because it’s not, it is well balanced, yet with more satisfying bass (for some) than the EA500. But that is also combined with a slight dip at 3.5kHz which helped to smooth things out even farther. And guess where else that 3.5kHz dip is? In fact the graph at 3.5kHz all the way to 5kHz is very similar in nature between the EA1000 and EW200. And if anyone knows that area of the Pinna Gain is very much a place where our hearing is most sensitive, meaning combine that Pinna Gain with a low-end that is similar and we have two IEMs that sound very close to the same. Though where the two IEMs start to differ is the EA1000 has about 4Hz less bass, That, and they are complete opposites at 14kHz. Where the EW200 peaks at 12kHz then again at 16kHz. Though again due to close proximity in the Pinna Gain area and similar in bass, they both offer FR signatures that are very close. The differences come with the quality of EA1000 bass technicalities that really separates the two to my ears, and the imaging in the midrange, which is noticeable better with the EA1000. Still if you were to listen to them back-to-back, they are birds of a feather.



Test 4:
SIMGOT EM6L: $109.99
1DD + 4BA Hybrid Drivers:
Laughably SIMGOT went hog wild with their Hybrid ideas here. Yep, you can study the graph here, except no way will the graph truly explain what is going on with bass extension. Sure the graph represents it, but you also have to take into account what the 4 BAs are doing to balance out what is all going on up-top. Laughably this is a Hybrid and the total opposite of what we have with the EA1000. One zigs where the other zags. But one look at that EM6L bass extension would have you believe the bass is maybe out of control, or sloppy……and that is just not the case here. The bass goes low, but it is clean and in control.

The BAs are more (slightly) metallic and not holding the density/girth (note-weight) of the EA1000’s treble or midrange, the EA1000’s bass is more refined and over-all this single DD means that while stage is nice, it doesn’t quite have the total (side-to-side) positioning of the EM6L. What we get are the (plain and simple) regularly understood methodology differences here, where the EA1000 is more cohesive and together and the EM6L more dislocated and fragmented in response. Does it make one better than the other, hmmmm I guess it would depend on what you are after? Normally I like Hybrids the best, but the way they did the EA1000 it almost doesn’t sound like a DD, it almost sounds like a Hybrid? I know I sound like I just contradicted myself, only if you're wondering what the best part of the EA1000 is, it doesn’t really sound like a single full-range DD?

https://www.head-fi.org/showcase/simgot-em6-l.26639/reviews#review-31512

In the EM6L review I go into more about the graphs and the various targets SIMGOT has focused on. And while it’s safe to say the EA500 (red nozzles filters), and EW100P were more are less focused on the 2016 Harman and the EW200 and EM6L were more in line with the 2019 Harman, still these summaries could be considered over generalizations. Still whatever Harman (2016/2019) your direction is, it does give an overall characteristic to the sound, as such these generalizations are applicable.

SIMGOT EW100P: $19.99
10mm Dynamic Driver:

This IEM didn’t get the best review from me. It’s not because of price, as I gave the 7Hz Salnotes Zero a great score, I just thought the missing low-end combined with the forward midrange was just not a good combination, plus the overall sound was boring and had no personality?

Cables:
Once again there is absolutely nothing wrong with the included cable, only using these aftermarket cables enabled the use of 4.4mm balanced amplifiers which at times are better suited for playback.


ISN G4 Cable:
To tell you the truth, this is one of my absolute favorites with the EA1000 IEM. Why? Added is note-weight……..even bigger than is found naturally with the EA1000. So much of this could in-fact be partially due to favoritism, which I’m not immune to. I use this cable all this time. But what it gets you in the case of the EA1000 is separation, and a tone-down of treble. There is a resulting smoother 14kHz peak, and a more sculpted low-end, like from a blacker background. So it totally makes the sound slightly smoother yet with an added stage expansion that is totally different from the HiSenior White Whale. Where there is a lower midrange added thickness to the White Whale, where the G4 makes the lower midrange cleaner and clearer. What this gives you in the end is increased imaging into the stage, all the while a slight overall smoothness that is rarely found together with the expanded mids into the stage. I would suggest this to those that want to access 4.4mm balanced.....simply get the G4 for the EA1000!


Penon ASOS Cable:
A more natural idea of a cable response, not to say that the G4 colors the sound, except the G4 is maximizing the Graphene tone and character to the fullest extent. Where here we are enjoying a bigger more straight forward size of stage increase and evenness of demeanor. None of that drop in low-end through sculpuring and added thickness or (better yet) contrasts as found with Graphene. Big imaging size, grander stage……….of course there is no way of truly knowing as we have switched over from 3.5mm to 4.4mm.....thus a totally different amplifier in the WM1A player. Offering faster note attacks and note fall-offs into which the EA1000 has the room for, while still maintaining the overall sound signature and over-all EA1000 personality. Maybe slightly the most energetic of cable tests today?



HiSenior White Whale Cable:
Thicker, meatier than the regular cable, how much of that is the different amplifier in the Sony WM1A is debatable. A fuller lower bass than the ASOS and slightly more forward than the G4. Part of what the ISN G4 is doing is setting some lower frequencies back, into the backseat, to enhance the feeling of a darker yet more forward midrange, with more note-weight and a wider girth of expansion. Here we are more like the ASOS, except slightly thicker in the lower midrange. The ear-hooks make the White Whale a joy to use.

Included Cable:
The silver plated Litz Structure is amazing. Having all metal hardware it includes the perfect ear-hooks which are not too aggressive or weak in daily use. The way the EA1000 sits with the included cable is something to behold. Even the sound with the included cable was something that I couldn’t get enough of, always going back to check on it. Pre-burn-in the sound was great with every genre except rock and EDM, though after about 130 hours of burn-in the supplied cable with the EA1000 had a certain sound that went with all music and all file types? I was especially taken with how the included cable acted in that it could be coiled into a small form and always laid where it was told. Also there were very little microphonic properties in daily use, which I found surprisingly good. A nice touch was the all chrome hardware and gold chin-cinch.




With regular phone use:
Due to the enhanced note-weight of the EA1000 it was totally enjoyable in regular phone use. While definition and stage were not quite as dramatic as with a dedicated Audiophile DAP, the differences were small, and may not be a big deal to some. There was better perceived darkness of background with a DAP also often the phone use was 75-80% of full volume. So the AE1000 are not hard to drive but does scale up with better equipment.

Out-and-about:
Normally I would not advise jogging with such an IEM, I mean most will have TWS for sports, except fitment here is incredibly special, at least I would have no worries with these ever coming loose in public? Even the solid metal design adds to the noise occlusion, meaning you see all these vents on the back and think they would be open sounding to let outside noise in, when in fact they offer really good sound occlusion. I would even suggest jogging if you so wished, as they simply fit that good and never move out of place with the supplied cable.

Packaging:

Build:
Coming in at 11 grams a piece, the EA1000 is one of the heavier IEMs on the market, though lucky the form factor is also on the medium size. This accomplishes a really important aspect to ergonomics, in that most of the actual IEM weight sits inside your ears. There are no sharp edges so they simply glide into place and stay put. The outer surface is glass but somehow they fail to ever show fingerprints? So counting the glass you have four basic pieces in that the nozzles are removable for sound design. The cable plugs are ever so slightly recessed and the actual nozzle length seems just right? The passive radiator really adds to the feeling of openness and bass texture? At least this was my very first impression of how the EA1000 was different in its IEM price category. My regular go to ear-tips were fine as well as the included SIMGOT tips worked well. This is always a good thing when you can get fitment with a wide range of ear-tips, and the fact that the IEMs themselves never seem to move to where you lose the air-tight fit? Surprisingly the bare metal shell of the EA500 was a fingerprint magnet, yet here even the sides don't show smudges, and I don’t have an answer as to why? This is an IEM I never polish-up or feel the need to?



Music:
Here I will take a few albums to help describe what the SIMGOT AE1000 does.

Arrival
44.1 kHz - 24 bit
Here we are met with an electronic soundscape. Often music like this can be scathing or unlistenable on the wrong set-up. Here I’m using a MacBook Air hooked-up to the Shanling UA3 and have met with an enjoyable soundscape. Here even though the signal in the bass frequency department seems uneventful or even with-out consequence, in fact it is the essence that is showcasing our beautiful bass transients. That even though small in changes........the bass texture is enveloping and unique…….at 02:16 a single drum beat introduces us to the rhythm. At 02:43 a symphony of electronic effects and additives takes place. Yet at 04:00 all is back to normal again, yet there is a background of white noise that is fascinating. I chose this song because the themes it introduces are subtle and provocative. Being it would be the immersion taking place which is at the price of everything else. Just this big towering bass drone, not really going anywhere and helping us find the moment in which we are spellbound by the minimalism of it all. In fact there was a dog barking and I had to check if it was in the song, of course it was not, but it went with this style of tune! There is the use of only a single drum beat, only a one hit………yet it is complete, yet still sounding like more of a sketch than a song…..but that’s OK as I have found complete entertainment, possibly due to the transducers used?

Now the previous first song makes total sense here, as it had to exist as a gateway to where we were going. Any ideas of sketches were then fully formed into life in the next song, which is really a continuation of the first song. Now instead of dogs barking I hear what sounds like water dropping? And……I’m sure this time it is in the music. This is the kind of music that will remain at the absolute minimal process and border on boring for a moment until that one part hits to make it all make sense, even to the prior song section. These are very light and inconsequential forms of sound design, yet enchanting when you can enjoy simply the tones they are reaching for. There is nothing more or nothing less, as this experience is captivating yet it is what it is.

HA, this is all starting to make more sense as the prior songs are the perfect set-up to what’s going on now. And yes, it was all totally worth it (to be) here, to be dragged along up to this point in time. And in-fact I am hearing the greatest synth-bass here even at the start……….at 00:13 hahah. This is where we were going all along. At 01:35 there is a climax of sorts, where we have entered the message of the album. At 02:34 the bass drones are provocative and entertaining to say the least. At even the 03:30 you can tell there is going to be 01:40 more minutes of this minimalism, and that’s OK, it is like the end of a day as the sun has just set over the ocean and the beginning of night approaches.

Gdanian Induction conclusion:
This was an interesting first three songs. Many times I will use instinct to try and discover how new music goes with a new IEM. I mean you normally know right off if something is working out, that there is value to be found. And the crazy part was I really didn’t become blown-away until the third song, yet it all seemed to work. The fact that this recording is absolute in the minimalism it used to drive at success. That in many ways the music had you lusting for slightly more (especially) bass and provided only just the amount needed to move the songs along, up till the third song which provided the sonics in ample amounts. Such a trick is the very opposite of too much, that they are stingy to give you what you want, which in-turn makes you want it that much more, when it all finally hits home. That in-fact the EA1000 was along for the ride, simply relying what it had (to work with) in the best of form, that when the third song hit those layers of bass and effects made for a profound and emotionally moving experience. That this minimalism has brought me back to my original audiophile roots, that it is with-in sound design that we can take a form of realization inside the beauty of an individual series of tones. Just hearing these tones come across can show us the complete imagination of creation and poised positioning to only include what is needed at the very basic level to make it work out.

Intermission:
The remaining 4 songs were all played using the included cable and my regular wide-bore tips with the Sony WM1A with MrWalkmans software. No EQ was used.

Here I must admit was my favorite song upon first getting the EA1000 in my ears. And now hearing it once more allows me to partake of such a musical experience in full form. At a full length of only 02:47 this number packs a punch. Even at the very start right at 00:16 the deepness of the reverb found surrounding the drums and the fall-off into the stage makes the song fun. Though it’s the deep layered violin samples which exist at the 00:30 mark that once again begin to move the emotions. Such violin stabs are found to be transfixing in their attainment in the stage? Does listening even get any better with any other IEM? Those are the style of questions we are forced to ask ourselves. At 00:43 the sampled chorus is all I need to become enamored with this song, and it doesn’t matter how many times I hear it played back. For here the layers and the intrinsic relationship between each and every facet of this song makes my day….I’m moved? At 01:21 there are added rhythm accents which seem to show us the distance of our stage size, and inside their display I have all the stage I wish for, seemingly coming to life, these samples from the very farthest reaches of the stage. At 01:40 there is a syncopated sequence of lower bass throbs that while not the lowest I’ve ever heard, are still clean and fast……making the song for myself at this single point in time.

44.1 kHz - 24 bit
Ahh the lows at the start? Now we are getting somewhere? HAHA? What? Even at 00:14 the depth and airiness achieved is with-out competition. This, this is why we are here, and the very reason we have ear-monitors in our ears. All the work SIMGOT has accomplished to get us here at this exact place in time, the transients held with-in how the bass notes are attacking……..pure gold. If you end-up purchasing the EA1000 definitely try this music out as it’s a perfect example of just how good this IEM can be. At 00:23 just the way the lows are imaged into the stage, taking form into an element all itself. The shape, the size, the timbre……it’s all so very good, need I say perfect? Part of this comes from the layers of bass, that it is created as a layer upon layer of bass tone, and the EA1000 takes such tones apart. Such a display of texture is not able to be shown with the 7Hz Legato, it’s just not this clean and precise in the bass department for this level of extraction. At 01:01 the strings show-up to add to the instrumentation, seemingly going along and just another additive to our musical involvement. At 01:17 the chorus comes in and again I have basic chills……here. Yep, cheap thrills over at Redcarmoose Labs…………….What can I say? At 01:27 there is a threshold to how the bass interacts with the rest of the song, seemingly dropping out of frequency range, and that lowness, that extreme point of playback, we are here right in the moment with the EA1000, going places, places never thought of being a part of? Laughingly at 02:22 there doesn’t seem like there are any more sounds to throw at us, but they take this whole affair to the next level? Where in many ways the next game soundtrack (Forza Motorsport) in this series of tests is not at this epic level. Where Forza Motorsport almost doesn't have enough to exist on its own as an involving piece of music. Yet this Grand Turismo goes to the farthest place to let you know it can exist as music all by itself, becoming entertaining and moving just by sheer amount of information overload. This song ends as my favorite in testing, showing the extreme abilities of the EA1000 to go the extra mile when the music calls for it.

Such a song promotes this wildly enchanting low end, which seems to go even lower in areas. Added to that big synth embellishments which are totally fun and enveloping the ear-stage. Ahh what else do you really want that this song doesn’t provide? Huh? Even though the song is on the shorter side of songs, there is a lot to chew on, as a sound example there is nothing wrong with playing it over and over again, as so much is going on here. The warmth of the song writing, the full-on execution of recording it……perfect really.

Head Down
44.1 kHz - 24 bit
Taking us home on our investigation of music today is a dramatic digital soundscape offering a straight up and forward, simple display of characteristics. A simple yet complex display of theme music offering clear and precise tones which when done correctly fully show how the EA1000 acts. At 00:18 a keyboard harmony is yet simplistic and effective showing us just how the EA1000 displays tone. Here we can also judge the bass line in that it’s tight and controlled in perfect focus, yet we don’t need anything more, we don’t need anything else here. The sound is fresh, exhilarating and complete. Probably the best feature here are the layers, that while our stage is not the very biggest in the IEM world, we are gifted with incredibly precise layers which are in perfect contrast to one another. That in fact each element here has correct relationships to how the song was performed and arranged. Such display of performance focuses on the areas of contrast and the correct mix within itself. Just the fact that the reverbs are natural and vivid for how they are utilized. At 01:21 the keys again take precedence, in that this is the song’s highlight, being this is an instrumental theme song. But more than that, the keys have a specific reverberation into the mix, a fall-off that is very specific and heard for how it’s done here. It’s the balance of bass emphasis and the fact that we can hear everything in order, the way the producers want us to, I hope? In a way this music is cheesy except it serves a purpose in that it is supposed to be background music while the video game is played, so in hearing the OST, it’s really only part of the total experience. Still the style of music holds enough interest that there is a lot going on here, with the fact that new elements are continually added in. At the 02:20 mark there is a style of breakdown as to where there is both drum and bass accents. All of a sudden we can notice every part of the song structure being laid-out and layered in place. At 02:43 there is literally just bass for a moment and yet the EA1000 is showcasing just how well this section is done. At this single place the sub-bass exists all by itself for a moment and we are at one with it. But of course nothing stays the same and the song enters into full-effect once more at the 02:44 mark. This style of music performs a kind of guilty pleasure in that it’s nothing more than background music for a video game, yet so well done and so complete that it makes for a memorable listening experience when played back well.




Conclusion:
To me, SIMGOT is one of the most successful manufacturers of the year. Why? They simply make good IEMs. And of the six different SIMGOT IEMs I’ve heard I like the EA1000 the very best. Sure it’s the most expensive model I have heard, but I also feel they have introduced new technology which has moved the sound forward into a new dimension, at least that’s my opinion when I put them in my ears. Quite simply a quality of tightness and evenness that I feel SIMGOT was going for and achieved remarkably well. Yet what is the most remarkable is the fact that anyone can purchase and obtain this sound for $219.99. The fact that there is a basic build that is exceptional, that they fit with-out moving anywhere else, and stay in one place. The fact that while slightly heavy they fit inside your ear, so the weight may be part of the key to the sound, absorbing any unwanted vibration? The fact that the extra box accessories are usable and nice at this price-bracket. The cable is truly gorgeous and was used though-out the music testing process to achieve great results. The extra nozzles are there if you choose to use them, where if anything they do actually work to dial-in the sound to various target curves. The box opening experience is very different and shows how SIMGOT is trying their very best to guarantee your satisfaction in the box opening experience. But to me most of all the important thing is the realization of a specific tone. That SIMGOT has a style of playback that is both clear and balanced, the playback asks for personal involvement. The playback draws you in possibly due to the layers and note-weight? The fact that the bass is truly unique here, really unique at any price. Offering exceptional texture and a style of airy-agileness that just won’t quit. The way the bass forms into a place in the stage simply warms my heart, and adds a thrill in my daily use. All this is slightly different sounding than out of the box, I mean the SIMGOT EA1000 changed after 130 hours of burn-in, I can’t leave that part out? To where at first they were amazing, but became so much better IEMs at playing all genres and file types after burn-in. The fact that the mids are full and accessible exists to showcase layers of detail, all coming across seemingly totally correct and never too hot. The treble is also nice being it has a charm in that there is enough sparkle and pizzaz, yet still total cohesiveness that is the hallmark of single full range playback. With-in this cohesiveness exists a fully natural and correct timbre, that again is the very reason full-range dynamic drivers are even a thing nowadays to begin with. That this level of quality is offered at $219.99 is by far one of the best audio deals of the year. That finally we are not really at a place of subjectivity here, that anyone and their Mom couldn’t help but find value here. That even if the SIMGOT EA1000 was 1/4 less as great (in sound reproduction) it would still gain my full five stars review, and that simply goes to show how over-the-top SIMGOT have taken things for 2023……….to a place previously unforeseen, into the realm of science fiction. It’s this science fiction realm made into reality that has made this review so much fun to write, that in 2023 there is a product that simply outshines the competition on every level……..that is what Head-Fi is about!

Build Quality:
Build is exceptional, all metal shell, refined and classy look.

Tuning Nozzles:
Red: Bassiest, with a slight reduction of the mids and treble.
Black: Felt the most balanced, in the lows, mids and highs.
Gold: More elevated upper mids and treble.

Sub Bass:
The sub bass extension is really good on the EA1000, it gets pretty deep, has a natural texture and rumble, hits just right, with good weight and a natural decay, and gives depth to the sound stage.
I don't think I've personally heard another single dynamic IEM, that has the sub bass extension of the EA1000.
The bass is also pretty clean and well textured, pretty natural too.
The amount of perceived sub bass also depends on the nozzles you choose, the red nozzles felt like they gave the most bass, with the reduced treble and mids, while the black nozzles has the most balance between the sub bass, mids and treble, while the gold had a bit more of the upper mids and treble extension.
The sub bass doesn't really seem to bleed too much into the mids, maybe slightly, but it's well controlled, the lower mids are warm and lush too.

Mids:
Mids are fairly natural, good texture, warm and inviting, not too forward and not pushed back either, also not harsh at all in the mids, and depending on which nozzles you choose, will effect the mids and treble a bit.
I personally preferred the gold nozzles myself, for the bit of extra extension in the upper treble, and gave vocals a great natural tone, with a little bit extra micro details.
Male and female vocals sound great, they have plenty of warmth and great texture, very natural.
Guitars, base, electric and acoustic, as well as pianos all sound really natural, with great resolution.

Treble:
The treble is quite detailed natural and has good micro details too, and there's good extension in the upper treble, with a good sense of air.
Especially with the gold nozzles, the treble had the most clarity and micro details with the gold nozzles, but it could be a little bright for some, who are more treble sensitive.

EA1000 Vs EA500:
The EA1000 has a more detailed, more pronounced sound, with better micro details, better resolution, fuller, deeper sub bass, a more holographic sound stage, with more micro details.
The sound stage of the EA1000 also naturally has more depth than the EA500 too.
Vocals and instruments are more resolved, clearer, more natural on the EA1000.
I believe it's a step up in the same kind of way the EA500, is a step up from the Simgot EW200, where it has a more mature sound, with a more resolving character, such is the case with the EA1000, you go up again in resolution, micro details and stage depth.
I think the EA1000 offers a great value for money in its price range.
It's a more superior upgrade to the EA500, with a more premium built and accessories package.
Well that's about all I can say on the Simgot EA1000.
It's been an absolute pleasure to listen to.
Thanks again to Simgot for sending out the EA1000 for review.

Introduction

Are SIMGOT the IEM brand of the year? It's hard to argue with an incredible run of releases throughout 2023 that has culminated in, quite possibly their piece de resistance, the EA1000.

Fermat's Last Theorem, stated in 1637, perplexed mathematicians for over three centuries. It proposed: no three positive integers a, b, and c satisfy the equation an + bn = cn for any integer value of n greater than 2. Many brilliant minds failed to prove this elusive theorem over the years until finally, in 1995, Andrew Wiles presented his (corrected proof). I was in senior school back in 1993 when he had his first stab at it, and I remember at the time my school making a seriously big deal about it - if you saw the alumni from where I went to school, you'll probably understand why, but put it this way - I doubt any of them are furiously trying to recount the details to help them review their latest set of IEM's now thirty years later!!

The EA1000 pays homage to this mathematical mystery, as SIMGOT's journey to master their own house sound (finally with a deviation away from Harman!) echoes the unwavering persistence required to prove Fermat's theorem...ish! After honing their craft with previous models like the EM2R, EA500 and EW200, SIMGOT have rounded off the year presenting the EA1000 as an encapsulation of their learnings - a beautifully crafted IEM that might just resolve the equation of <$200 = supreme audio fidelity! Wiles was knighted for his travails, and even earned the 2016 Abel Prize - I'm pretty sure SIMGOT would be happy with IEM of the year in the New Year's Honours List, and at least as far as I'm concerned, they're looking pretty damn good for it!

The EA1000 includes some pretty impressive tech. It isn't cheap - $219.99 - and you would be forgiven for being slightly taken aback at what is, on paper, a single DD arrangement. However, this is where cutting through marketing bullsh*t is essential - firstly, they've used 'SPGD Technology', a special diaphragm manufacturing process which results in a high rigidity, lightweight diaphragm coloured in purple-gold. As you'll see later, the macros bear testament to its existence at least! Secondly, DMDC, or dual-magnetic and dual-chamber driver technology is geared up to provide exceptional dynamic range and precision high-frequency performance. Finally, the 1DD plus 1PR architecture means the pairing of a single, 10mm full-range dynamic driver and a passive radiator for a more responsive full range with improved stability and driveability.

They've also chucked in replaceable nozzles, giving you three target curves:

Gold Nozzle, Gold Curve: SIMGOT-Golden 2023 Curve
Red and Steel Nozzle, Red Curve: Harman 2019 Curve (pre-fitted)
Black and Steel Nozzle, Blue Curve: SIMGOT-Classic Curve

So essentially, you've got a single DD which breaks away from the usual production process and materials. You've got a passive radiator to get more from the lower frequencies, and you've got an overall arrangement that is designed to enhance clarity and imaging, giving you a fuller, more precise sound. And to top it off, you've got three different sound profiles in the box based on your personal preference.

The EA1000, or at least the tech they've included, is over three years in the making. Was it worth the wait? Let's find out....

Unboxing



To unveil the true beauty of the EA1000, I suggest watching my YouTube review, because still images really don't do it justice. The shiny, 'milk tray' purple and gold outer exterior mirrors the purple-gold diaphragm technology I waxed lyrical about in the intro, and the focus on the front is very much the theme SIMGOT have applied to the release - Fermat's Last Theorem.



This theming continues as you peel back the layers of the box to reveal the array of accessories, which include six pairs of eartips, a stunning, shimmery high purity silver-plated OFC Litz-structure cable, the three detachable nozzles I mentioned in the intro and some coloured rings to denote and identify the nozzle.



The carry-case has a magnetic, flip-open lid. It's leather-look, with the SIMGOT branding on the top.



The back continues the theming with the expression 'Salute to Art and Science'. The case is a decent size, measuring 97 x 71 x 38mm.



There's plenty of space inside the case to fit the IEM, the cable, the spare tips and the spare nozzles, which come fitted into a screw plate so they won't be easily damaged if stored inside. Here you see the shimmering properties of the cable in the sunlight.



The theming continues, with the warranty card not able to escape a brush with Fermat!

Build Quality and Design



In my review of the EM6L, one of my minor quibbles was the resin design, which lacked a little curvature on the inside. With the EA1000, SIMGOT remedied both of those issues effortlessly. Despite weighing just under 11g per IEM, the EA1000 is a delicate, lightweight, beautifully designed IEM that combines a fingerprint-magnet-high polished steel body and patterned crystal glass faceplate with an elegant profile that looks as good in the ear as it does resting precariously on a railway bridge above!



On the inside, note the improved curvature, which we also saw in the EA500. This gives the EA1000 better fit and improved isolation. Here you also get your first glimpse of the passive radiator, and what the IEM looks like with the nozzle removed.



While we have the IEM open, here you see the Puple-Gold SDPGD driver in all it's glory.



Move to the outside and you'll find a slightly recessed 2-pin connection terminal and the 'Fermat' insignia. Whilst testing the sound with each of the nozzles, I got a few snaps - here is the EA1000 with the gold nozzles fitted. I enjoyed all of the sound signatures, as I'll come onto in the Audio & SS section, but whilst the gold nozzle looked the best, it wasn't my favourite of the three sound signatures sadly.

Removing and replacing the nozzles is a simple and pain-free process. The stock and black options have some black foam at the base of the filter, whereas the gold has a thin membrane with a hole in the middle. Removable nozzle mounts and filters allow endless sound fine-tuning without compromising comfort. Each earpiece contains threaded nozzle sockets, letting users swap between included targets with ease. The nozzles themselves integrate securely while permitting adjustment.



Here you get a glimpse of the fit of the EA1000. There's no pressure on the tragus at all - the line you see here is from me pulling the ear hook back. It's an extremely subtle design which doesn't protrude regardless of side or front profile. The ear hooks are quite loose - this makes them super comfy, but it impresses on you to get the fit right from your tip selection. I've tried a few different tips and so far none fit better than the stock.

The IEM measures 22mm (height) x 17mm (width) x 20.7mm (max depth) - it's noticeably leaner looking than the EM6L, but very similar in dimensions to the EA500.

Looking closely at the construction, it's very evident that no corners were cut. The metallic shells exude precision craftsmanship with their lustrous chamfered edges, and their robust but streamlined profile strikes an ideal balance between aesthetics and durability. Both the EM6L and EA1000 rank among my most comfortable IEM's, making them both ideal for long listening sessions, with the EA1000 edging it thanks to that more tailored inside profile. They aren't as bulky as many of their competitors, and the nozzle length and depth seems to be optimal for a non-invasive, fully-immersive experience.

Audio & Sound Signature



As per the intro, SIMGOT claim to have leveraged innovative driver technologies to deliver pristine audio reproduction. At the heart sits its new purple-gold sputtered diaphragm, crafted through a complex multi-layer deposition process for optimal rigidity and low mass. This enables the 10mm dynamic driver to resolve the finest details and dynamics with minimal distortion.

The diaphragm pairs with a dual-magnet motor system for enhanced control across frequencies. This dual-magnetic circuitry widens the dynamic range and transient response compared to traditional single-magnet designs. Treble reproduction sees particular improvements, providing crispness without harshness.

A rear 6mm passive radiator adds tactile bass texture and natural ambience. It resonates symbiotically with the front dynamic driver to augment low-frequency presence and dimensional realism through its added airflow interaction. The effect is addictive, highly detailed bass that is palpable yet controlled. There are no coherence issues due to the unorthodox but highly effective driver arrangement.

The three filters provide three different sound signatures, as shown here in the FR measurements above. Regardless of which filter is used, the EA1000 has a natural, accurate tone, even moreso than the EM6L, and the beauty of not using a BA. Natural tone has characterised all of SIMGOT's releases this year - even the low cost EW200 - but it hits new levels here due in no small part to the magnificent lower frequencies, masterfully facilitated by the passive rad.

The Red curve is the stock curve, based on the Harman 2019 target. Out of the box, the thing that hits you with the EA1000 is the vast, expansive soundstage that immediately places you at the centre of a disparately-assembled orchestra. The midrange on the EA1000 particularly impresses, with clarity and naturalism. Vocals dazzle with their intimacy and nuance, marrying richness with airy transparency in the upper registers. Instruments similarly feel lifelike with striking realism.

In Paul Wasabii's review I noticed he used Madonna's 'Holiday' as a reference track, and using that as an example, the cowbell, tams, shakers and other percussive elements in the intro expand before your horizon, with wah wah guitars entering from a distant point to the right with precision positioning. The wasp-style synth and bassline are lightweight but controlled and full of texture, and Madonna's vocals sound as sweet as they ever did, with her gasps perfectly evident.

Move over to 'All of Me' by John Legend and you get another glimpse of how well the midrange is handled on the EA1000. The piano intro sounds articulate - full but crisp at the same time, whilst John Legend's vocals dissipate around you with an engaging resonance at the centre. The midrange timbre is very natural - regardless of male or female vocals are clear and open with great depth. The midbass depth is dense but the bass is well controlled - there's no bleed or blur, everything is immaculately controlled.

Putting the bass through its paces with Hans Zimmer's Time showcases the impact of the passive radiator. The EA1000 isn't a bass canon, but the lower frequencies have magnificent depth and resonance. It is a thick and fast bass response that is tightly controlled - layers and layers are knitted together very smoothly and naturally. The boosted bass leaves a visceral impact without bloat or muddiness. Its outstanding texture and detail are rare among even pricier competitors.

The treble captivates with its smooth, effortless extension. Cymbals shimmer brightly without aggression. The added airiness provides a pristine top-end complement to the resonant bass, avoiding harshness or sibilance. The tightness, control and accurate decay and reverb are illustrated nicely in 'Good Times' by Chic, where you can even hear 'fingers' in the claps. Yusef Lateef's 'Bishop School' brings tambourines, horns and sweet-sounding flutes to life around you as the stage sweeps out before your very ears separating very clearly. Really incredible stuff.

The EA1000 are better served with jazz, classical, opera, and generally orchestrally-complex tracks than more energetic genres, where they can feel a little too immersive, leaving you to catch your breath a little.

Micro-details and technicalities, as you probably guessed, are top tier - especially so with the 'Red curve' filter. It's a transparent and analytical sound that still offers great dynamics. The 'Gold curve' nozzle expands the soundstage even further, but detracts a little from the depth. The sound is a bit too bright for my liking, with a cleaner, leaner and more analytical sound to it that dulls the bite of the trebles and boosts vocals. The black ring nozzle is a bit more sparkly with more energy - I can't quite decide which curve I prefer so I reserve the right to circle back to this review and edit in the future!

Summary

Once again, hats off to SIMGOT for a remarkable release that well and truly stamps their authority on the IEM market. They got pretty much everything right here, from the overall experience and accessories to the build and design, and most of all the sound signature. It's easily a five star review that remedies man of the 'areas of improvement' noted in their previous releases.

The soundstage and dynamic performance are so moreish that I haven't used anything else since I got them. They aren't for pure-bassheads and the presence of the upper mids may be a little much with the stock nozzles, but the three filter options means there's probably something for everyone here.

In the sub $200 category, there's quite a bit of competition for your hard earned dough, but the EA1000 convinces with a super-textured, airy bass, lush mids and sparkly-enough, natural trebles. Its expansive soundstage, natural timbre and excellent resolving capabilities all constitute top-tier performance, and the straightforward driveability and coherence put the icing on the cake for a well-presented, great looking, high performing IEM that cements SIMGOT's seat at the top table.

Is it my IEM of the year? So far, I think that's a resounding yes.

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!

These iems have a sonic signature and a quality to them that reminds me very, very closely of my beloved Sennheiser HD800S. I would dare say that these are a sort of iem version of them. No, they are not a sort of "cheaper version", but the sonically "equivalent version", in the sense that the audio quality leaves nothing to be desired compared to the HD800s (except for soundstage -but that is normal, given that they are full size headphones-). I am not saying that the HD800s are bad. In fact, I love them. I am just saying these Simgot EA1000 are THAT good. Happy listening to all!

Introduction!
Hello friends!
Today we’ll talk about new hybrid headphones from SIMGOT, the model is called EA1000 and their cost is $219!
And they come in a very attractive, well-designed medium-sized box, and on the front here in the frame there is the inscription the last theorem of Fermat!

Well, here at the back there are three frequency response graphs of headphones with different replaceable complete nozzles, the first is Target Simgot 2023 with a gold nozzle, the second red is the already familiar Target Harman 2019 with a silver nozzle and a red silicone rubber band, and the third blue is a classic Simgot Target using a silver nozzle with a black silicone rubber band, and as always, the technical characteristics are immediately indicated and 1 dynamic driver 1 and a passive radiator are responsible for the sound, and the sensitivity of the headphones is 127dB and they received 16ohm impedance!

Let's take a look at what's included!


The headphones themselves are very securely fixed here, and they look very good. Let's look at them in more detail.
They have a metal body that still collects prints, of course, but nevertheless literally attracts the eye to itself, because they really look very elegant and tasteful, and as you probably noticed there is a logo of the company Simgot on the front part, and the hidden inscription Fermat here below.

And of course they got a good and time-tested 2pin connector that is slightly recessed into the case, and on the inside of the earphone there is a marking of the right and left channels, and a metal mesh is visible, and there are also two acoustic holes, one of which is quite close to this nozzle, which can be unscrewed and changed to either of the other two.
Ergonomics and convenience!
The fit of these headphones is excellent, quite tight and they fit well to the ear, so there are no problems with sound insulation!
Accessories!

In the smallest box there are replaceable nozzles, one of them is gold and has a transparent elastic band, and the other is silver and has a black elastic band and spongy material inside, personally I used a complete nozzle with a red elastic band, but I pasted an additional black filter on top of it, and I'll explain later why I did it.

In the box with the inscription storage box is of course, here is a really very good and strong case inside which there is an excellent cable that received a 3.5 jack connector and 2pins for connecting to headphones,i really liked it very much.


And in the last slightly larger box, there is a very good set of ear pads that can be used without problems, and additional elastic bands for use with nozzles, and here are such large instructions.

How do these headphones sound?
Well, now friends, let's talk about the most important thing, namely the sound of this model!
And this is what their frequency response graph looks like: there is a moderate amount of bass with a good entry into the mid-range, and a smooth transition to the upper mid-range with high frequencies that received a little emphasis, and upon first listening you immediately notice detail, attacks, transients, a lot of air, and a very transparent and ultra-analytical presentation that I have not seen for a long time, and these headphones literally pull out all the nuances in the music.

Low Frequencies:
Well, let's start with an analysis of the low frequencies, where the headphones demonstrate a very precise and accurate and correct rise with a slight emphasis on the sub-bass, which has excellent weight and volume filling the space, and I was very pleased with the smooth and clearly controlled transition to mid-bass, due to which the bass is perfectly controlled and literally allows the mid frequencies to breathe and open up without interfering with them at all.
The midbass here is presented as quite dense and collected and with a very clearly defined attack and good textural elaboration, and it’s worth saying that despite the fact that this is not a basshead model, I was very pleased to listen to electronic music and hip-hop genres, where first of all you need a good and pumping low end, of course, without obvious dominance over other frequencies, as this is especially happens in basshead models.
Mid Frequencies:
Well, the mids in these headphones are literally what you need, they are very transparent and clearly focused in space, but they feel a little light, but nevertheless I would say that this is literally their calling card, there is a great airiness here that makes everything sound clear separate and detailed on overtones, there is no box effect or closed dark space,and this entire range literally breathes, and despite the fact that it is quite smooth, it did not get excessive obvious monitoring and dryness because of this, but on the contrary, everything sounds quite emotional and exciting.
But the vocal part, both male and female vocals, is presented to us as very clean and incredibly transparent and clear, and of course it’s worth saying that it’s immediately noticeable that the vocals focus attention on themselves and are brought forward along with the drum part and everything sounds literally next to you and this gives very nice immersive effect but what I have to tell you is that the upper middle area is quite bright for me out of the box, so I used an additional filter that weakened this excessive emphasis, but for example, I can’t know exactly how it will be in your case since perhaps someone will not even have to glue a filter here and will be satisfied with such a brighter presentation, since I know for sure that there are many such fans.
High Frequencies:
Well, as for high frequencies, they have a very good and correct approach to tuning, there is also a very pronounced technicality and there is an insane bias towards analytics due to which we have excellent separation of cymbals and percussion in this range, and of course it’s worth to say that the headphones are perfect for heavy and high-speed genres that require a good dedicated attack and a small but pleasant-to-hear underscore of the cymbals and I’m glad that they don’t merge the sound into a single whole, but on the contrary, all the cymbals at the top and each long aftersound sounds very detailed and separate, that is, the images are not lost in the mix and are drawn very accurately and legibly, the analytics here are really at their best, fans of this kind of presentation they will definitely be pleased.
Stage and stereo panorama:
In Simgot Ea1000 everything is in perfect order here, the stage itself is quite wide and optimal, it does not have artificial stretch, it is exactly correct and at the same time has an excellent slope in depth, that is, the space and instruments do not feel flat, but on the contrary, they have good weight and volume , and all the images are drawn in great detail and separately from each other.
My conclusion on these headphones:
SIMGOT EA1000 turned out to be excellent attacking, detailed and incredibly technical headphones that you will definitely remember for a long time, that truly amazing new product.

Review OF The Simgot EA1000​

Introduction​

SIMGOT has never launched an IEM that was not highly accepted or commended sufficiently for their sound quality for the price they're being offered, whether it be the EA500, EM6L, or any other of their high end or budget IEMs. One of the earliest businesses in the audiophile sector is reputed to be this Chinese enterprise. They were formerly well-known for their EN series, but they have recently resurfaced and launched a few IEMs that audiophiles like me have found to be rather pleasing. I have been interested in this company ever since I heard about their EN series, and since then, I have grown to love their products and the technology they actually uncover with perseverance, hard work, and dedication. Other than SIMGOT, I don't believe I have ever seen a company that is as open about the creation and application of their technology in their goods, which makes sense. It has taken some time, but I was fortunate enough to obtain their most recent model, the EA1000, which is a younger sibling of the EA2000 that has the same technology. I would like to make a few clarifications before sharing my actual findings.

Disclaimer​

*Since this unit tour was organised by the generous people at SIMGOT, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “EA1000.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the EA1000 based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

The dynamic driver of the EA1000 is a 10mm driver with a multilayer sputter-deposition purple-gold diaphragm and a 6mm passive radiator. This configuration is unique to the EA1000. Using the previously mentioned SDPGD technology, the dynamic driver is essentially a second generation dual magnet and dual cavity driver. Its older brother, the EA2000, has the same configuration. Compared to comparable metal-made IEMs, the shells made of premium alloy metal that has been CNC etched feel more robustly constructed. The SIMGOT brand emblem is centered over a white background in a stunning pattern on the faceplate. The eartips allow for an isolated fit, thus the shells' comfort and fit let you to listen for hours on end without experiencing any pain or weariness. The included cable has a higher texture quality and feel than the one that comes with the EA500. The cable contains a 3.5mm straight termination plug on one end and a two pin connection on the other. Three different tuning nozzles, a carrying case, six pairs of eartips in varying sizes, and a variety of red and black rings for tuning nozzles are among the additional accessories that come with the IEM. Regarding the technical details, the sensitivity is 127dB and the impedance is 16 Ohms. There is a 20Hz–20kHz effective frequency response.

Sound​

The EA1000 exhibits a common sound profile with vibrant, well-detailed, and resolved notes presented with the most precise note presentation I have ever heard from a single DD, yet it leans toward three distinct tunings. Although I am aware that there are passive radiators that help with the notes' natural reproduction and dynamic quality, I still think the dynamic driver is the most amazing. As I indicated, there are three distinct tunings that may be accomplished with three distinct tuning nozzles, enabling the tuning of two in-house targets as well as a 2019 harman target. For my part, I don't see any appreciable differences between the harman and their golden 2023 target—discussed later. Coming to the sound, I am using the standard tuning nozzles (black ringed nozzle) which they came with for more intricate findings. Regarding the sound, for more complex discoveries, I am utilizing the standard tuning nozzles (black ringed nozzles) that were included.The vocals and instruments from the lower mid range to the upper frequencies have a very vibrant and clear response that comes across as joyful and detailed, while the treble sounds pleasantly expansive, airy, and non-fatiguing.The bass feels accurate, slamming, and banging because to the excellent PR that was employed.Even though this is my first IEM to use a dynamic driver and a decent passive radiator, the tuning and sound quality really amazed me. It still amazes me that a single DD can produce a presentation with such forward-thinking, natural sounding quality and exceptional technical ability. Let's examine the sound presentation in more detail.

Treble​

I believe the frequency graph is not accurately depicting the situation because my perception of the response is different from what the graph indicates. If this is not the case, I will trust my instincts first. The problem is that I hear no issues at all. By this I mean that the reaction is deliberate, thorough, and astonishingly brilliant, and I don't have any problems with peak sound or sibilance.I think the singers and instruments sound richer and fuller because of the high treble's wonderful airy extension.Please bear in mind that I am discussing an IEM that costs less than $250 USD. The notes are precise and accurate, but they don't sound piercing in my opinion—rather sophisticated. The singers and instruments are more prominent in the lower treble, which adds additional energy without pushing forward too much to cause a peaky or shouty reaction. The lower treble sounds just as clear and detailed as the upper treble. The instruments and vocals are more prominent but still under control, preventing any metallic tones from being heard. Even when I compare the treble response of the SIMGOT to other IEMs around the EA1000, such as the quintet or Falcon Ultra, I believe that generally, the SIMGOT did the best job of finding the ideal balance between sounding as natural as possible and without being offensive.The quintet, in contrast to the Falcon Ultra, sounds more forward-thinking and aggressively detailed, whilst the latter lacks sharpness. The HYPE2, which likewise generates a smooth response with details that are similar to the EA1000, is the only IEM that I have seen that comes close. As a result, the treble area is presented in an expansive, intricate, and airy manner overall.

Mid Range​

In terms of tone and timbre, the mid range is where the response sounds the greatest; in my opinion, these are the best IEMs under $500–$800. Though I do believe that the placement of the vocals and instruments plays a significant role, I still think it is a great achievement that SIMGOT brought this IEM to produce such a lively response that makes the natural and forward response sound fuller, richer, and detailed at the same time. Many brands haven't come close to this level of performance. My observations stem from the singers' remarkable dynamic leaping throughout the response, which sounds multifaceted and simultaneously detailed, richer, fuller, and unique. When compared to the lower treble, the upper mid range adds more energy to the mix and permits greater clarity. The vocal and instrument tones sound well-balanced, with the instruments complementing the vocals while adding a charming presence when necessary to be more prominent in the mix without overpowering the vocals. The vocals are quite enjoyable to listen to, keeping you on the edge of your seat as they spread out far and wide. makes the temperamental shifts in the mix sound more full.To put it simply, I think the vocals sound the best of all of them. Yet, it doesn't sound as rich or velvety at the same time. When vocally prominent tracks are heard, the vocals occasionally bring out a little "ss." This doesn't bother me too much, but I still feel like I should mention it because the vocals sound more open and lighter. In addition to sounding clean, the lower mid range has good note weight and depth. Similar to how the vocals end on a clear and distinct note, the guitar's bass notes seem slightly thick but not overly dense. I would try the quintet or HYPE2 if I were looking for a more composed answer with fewer inflamed vocals. In my opinion, the Ultra has less open-sounding vocals than the EA1000 and sounds more weighted and real. Overall, the mid range is presented in a more rich, vibrant, and melodic manner.

Bass​

Getting to the bass The passive radiator, in my opinion, aids in achieving the bass's detailed and organic response, which also permits a quick attack and natural note decay, providing a realistic response. The bass is one that doesn't allow for additional prominence in the mix. The quality is sufficient to give the entire response a more sophisticated and grown-up tone. The emphasis is on the sub bass area, which extends nicely enough to provide punches and a deep rumble that aids in delivering notes with impact. Despite this, the rumble seems to be modest and constricted within the ear canal. The well-controlled mid bass produces a meatier presence, enabling both gentle hitting slams and clean, pounding bass. The response reproduces the notes' naturalness, hitting with just the appropriate amount of intensity and weight and resolving at a speed that feels authentic while still taking into account the higher frequency areas. Although the bass is not the highlight of the entire response, it is nonetheless underappreciated since it nails the live stage presentation rather than the concert one. In my opinion, the HYPE2 has a more powerful and thunderous sound than the other model, which sounds more organic and natural overall and amplifies the sound of the bass notes on a large stage. The bass on the EA1000 sounds more textured and sophisticated, even though the quintet sounds smoother and warmer in this aspect than the EA1000. The bass is similar to the Falcon Ultras, however less detailed and textured than the EA1000, in my opinion. In the end, I think there is enough bass response to make the reaction seem lively and enjoyable. As a result, the bass area is presented in a compelling, realistic, and fulfilling way overall.

Technical Performance​

In technical terms, IEMs in this price range sound better on average. Quintet, for instance, has a nicely detailed response with good separation and resolution, but it still lacks sharp imaging. I suppose this is because it introduced sibilance or shouty response. However, after hearing about so many IEMs that were unable to achieve what I believed, all of my concerns were allayed by the EA1000, which exceeded my expectations. Let's get specific.

Soundstage, Sound Imaging & Separation​

The stage is rather large and spread out, which contributes to the surround sound rather than a stereo sound. The depth and height feel significantly better than any other IEMs, though they are similar to HYPE2. The imaging is where the EA1000 excels, as I find it to produce a sharper and clearer response than any other IEM I have mentioned. The notes' separation helps me identify the source of the music because it sounds distinct and far away without being overly dispersed.

Speed & Resolution​

Although the resolution is superb, I think the quintet to be somewhat superior in that aspect. However, the EA1000 sounds extremely expressive in terms of both micro and macro aspects. The notes have a quick attack and fade, and the resolvability seems to time as closely to sounding pleasant and natural as possible.

Sound Impressions​

Tuning Nozzles​

Red Ringed Nozzle - As opposed to the black nozzles, the only complaint I had with the EA1000 was that the "ss" sound was muted, which resulted in a more balanced sound with more male vocal presence and less intensity from the female vocals.Apart from this, I don't see any discernible changes.

Gold Nozzle - The response sounded a little more weighted and the notes sounded denser when compared to the other two tuning nozzles. This helped the vocals sound a little more grounded and beautifully presented, especially the female vocals, but the spark that usually gave the vocals an exciting touch that kept me on edge was gone. However, nothing seems updated or different—only the note weight and density are highlighted. However, I do occasionally think the treble seems a little muted.

Sources​

Sony WM1A - The response sounded larger and more expansive with a more dynamic response when listening to the EA1000 with WM1A. The vocals, especially the female vocals, seemed a little shouty, even if the notes were more rounded. This was probably around the 2-4k range. However, the bass was louder and more thumping. The calmed energy overall, particularly in the treble region, was the only other discernible difference aside from this.

Tempotec V6 - The response was smoother and cleaner while listening to the EA1000 through the V6, but it also sounded more intimate and lively. The energy was regulated because it prevented any focus from being heard in the mix. The details were as they were, but because they weren't as obvious, they were less noticeable. While the voices sounded less open and separated, allowing the response to sound more relaxed, the bass felt more in control and linear.

Conclusion​

To sum up this review, the EA1000 far exceeded my expectations and lived up to the fanfare that audiophiles had for it. Nothing stands out as being particularly incorrect or distinctive from what any audiophile would find pleasing at first hearing. Its opulent feel and sound profile make it the ideal IEM for around $500. Vocal aficionados would adore the EA1000 for its deep and satisfying response that captivates your listening style. I wholeheartedly suggest it because of the response, which sounds as close to a faithful response as possible. Investing $1,000 USD is not necessary to experience TOTL level sound quality; the EA1000 will do the trick.

Simgot EA1000 - $219


Pictured above with the Simgot LC7 cable, sold separately and features modular jacks with 3.5mm and 4.4mm

Introduction & Caveats etc…

Any of you that know me will know I have quite a thing for single dynamic drivers, usually my preference in this hobby and I’ve explored a large number at this point. I’ve typically gone for mid to higher end sets and most recently reviewed the wonderful DITA Perpetua which is certainly at that higher end considering the $3K price tag.

Simgot have had a lot of praise in the community over the last number of months, they appear to have really caught the attention of audiophiles with a selection of products from their range that have garnered huge praise for the price to performance ratio - most notably it would seem the EA1000, the subject of this review.

When Simgot reached out to ask if I would like to try the EA1000 I was very happy to accept, and would like to thank Fia from Simgot for the opportunity - as always, all words are my own without any influence, payments, etc etc etc…

The EA1000 retails for $219 and available from many different sellers to include Amazon, Linsoul, Elise Audio to name a few.

A bit about me...

I worked in the consumer electronics industry for a large part of my career, and have been passionate about music and technology from as far back as I remember - even as a small child asking my Mum to put records on the turntable (Abba, Supertramp and Planxty if anyone is curious )

My music preferences are very varied - anything from classical to techno, indie rock to jazz and all in between. In my early teens I was a big fan of bands like The Cure and The Smiths (still am all these years later), and I was bitten by the dance music bug that arrived in the early 90s where I became hugely passionate about genres like techno, house, trance and IDM - I amassed a huge collection of records and CDs, DJing with the former at various parties and occasional pirate radio station slots - a hobby at the time that I never took further, but still own 1000s of records and my trusty Technics 1210 turntables are still going strong 30 years later, a testament to the Japanese engineering!

I am not a professional reviewer or anything remotely like it. I love music, and I love the methods by which we can listen to music - over the last few years, that has become an obsession with IEMs and related gear. I've bought and sold many, and held on to a select few - these have been anything from a $20 set like the Moondrop Chu, all the way up to kilobuck sets such as Aroma Jewel, the infamous 'Traillii' from Oriolus, UM Mentor, and a whole selection of my beloved single DDs. As part of this exploration, I like to share my thoughts on the various sets in my journey with the Head-Fi community, in the hope it might be useful to others. The massive caveat, is of course that 'your mileage may vary' - this is a highly subjective hobby.



EA1000 Specifications

• Drivers: 10mm dual-magnetic-circuit & dual-cavity structure dynamic
• Cable: High Purity Silver-Plated OFC Litz Structure
• Connector Type: Detachable 0.78mm 2Pin
• Jack: 3.5mm

Simgot it seems have some interesting technology at play here in the EA1000, with the use of their patented ‘SDPGD’ driver - that being a sputtered purple gold diaphragm & ‘DMDC' dual- magnetic dual-cavity dynamic. This driver is described by Simgot as “powerful effective magnetic flux makes the sound driver have more amazing performance, which not only greatly improves the dynamic range and transient capability of the earphones, but also provides a wider bandwidth range” - they expand on this to say “the “Fermat” EA1000 also enhances the control of high frequency, which gives the “Fermat” EA1000 a stunning dynamic shock and presence. As well as the high frequency characteristics of rich abundance and smoothness, rich air sense and ductility, the exploration of the upper limit of the dynamic is a step closer.” - in addition to this driver performance, there is a 6mm passive radiator which enhances the low-frequency, something I experienced previously with the much more expensive MA Eclipse ($1,199 or so...) which likewise had very distinct sub bass in particular, quite like that of a sub-woofer in a 2.1 setup. Anyway, leaving all the tech aside, the EA1000 does sound like more than a single driver.



Unboxing

I’m going to keep this pretty brief as there are numerous reviews out there already, but I still like to show a selection of shots as to what you get.











The accessories are somewhat basic but you get what you need:

• Storage case
• Selection of tips
• Interchangeable nozzle filters

Stock Cable

Unfortunately only a 3.5mm stock cable which I think is a shame even at the relatively low price, it has become almost the norm now to have 4.4mm and ideally options in the box to switch to your preference. It is however a nice lookling and well made cable.



Case

The case is a fairly typical style, which is practical for storage and has a nice extra feature of slots to store modular plugs should you purchase the likes of the LC7 from Simgot which has both 3.5mm and 4.4mm (and is the cable I've been using since the EA1000 arrived in early January).





I like also the net at the bottom, handy for storing spare tips or the tray with the various tuning adaptors.



Design & Fit



Long before these ever landed, I had always thought they looked eye-catching from pictures I had seen - they certainly didn’t disappoint when they arrived, looking and feeling every bit as good or even better. The shells are of a robust metal construction and while there is a bit of weight to them, this is not to the detriment of fit in my experience, i.e. they do not fall out of my ears when moving about which can be a risk with shells that have a bit more weight to them. I expect some micro scratches to appear on the inner sides of the shells due to the metal finish over time but nothing to report as yet - the outer shells have a nice patterned finish and as such I assume these should allow for a reasonable level of protection from scratches.

I find the shells sit comfortably in my ears, and provide a reasonable level of isolation - this will of course depend also on your choice of tips, in my case I’ve been using the Acoustune AEX07 in XL, now a go-to set of tips for a lot of my IEMs. I have used frequently out walking and around traffic and while they don’t block everything, it is pretty decent.

They are vented, so no issues with any pressure build.

Overall I find them very comfortable and could easily listen for extended sessions.

Listening Impressions

I’ve tried the EA1000 with a selection of DAPs to include the Hiby RS8, LPGT Ti, and the Sony ZX300 out and about. Just to note also, Simgot sent me the LC7 4.4mm cable and all of my listening has been with this rather than the supplied 3.5mm cable - the LC7 is sold separately for $79 (I do think the stock cable should have a modular option too).

The EA1000 to my ears is an IEM that is easy to enjoy or even love, I can’t imagine anyone actually disliking - a nicely balanced signature that is sufficiently resolving to produce good details from micro to macro, with a smooth and musical tonality - I haven’t experienced any nasty peaks in upper mids, nor any sibilance or harsh treble. Important to note, the vast majority of my listening has been so far with the the silver tube/red ring which I guess is the ‘standard’ or default option as the EA1000 ships with these attached - a harman 2019 tuning target which is quite universally pleasing. I hope to test the others soon and either include or update this review accordingly.



Lows

I can certainly hear and feel sub bass, the passive radiator doing a wonderful job of providing a tactile, visceral low-end presentation to these deeper levels. While the quantity isn’t massive, it is certainly more than adequate and of high-quality, plus nicely balanced in my opinion with the rest of the FR through mids to highs - nothing overpowering, nor I am left wanting with tracks that require good presence here. As noted earlier, it reminds me somewhat but to a lesser degree of how the passive radiator in the Melodic Artification ‘Eclipse’ presented sub bass with a feeling of being like a separate sub-woofer like in a 2.1 speaker setup. Mid bass has good solid impact for kick drums with a realistic sensation of vibration, likewise bass guitars have nice timbre and a good sense of reverberation.

Mids

Really excellent balance between clarity and warmth here, with ample space for vocals and instruments - the resolution providing plenty of detail, well defined and a great sense of instrument positioning in a wide field. The note weight is slightly on the thinner side, but has sufficient body for the lower mid registers regardless and portrays both male and female vocals very well. The all important ‘emotive’ connection is certainly present, and I find synths, strings, brass etc all highly engaging, realistic and captivating. Upper mids might creep into an area of sensitivity for some, I’ve found at times as instruments step up to this area that they just stay within my personal comfort zone - I think this is probably an area where tuning can be tricky to balance, as it seems this part of the FR needs a bit of a lift to provide an accurate account of vocals and instruments in this zone, and indeed what is then portrayed in a sufficiently captivating way. The

Highs

Treble is balanced seamlessly with the the mid and low frequency ranges, extending smoothly from the upper mid-range and offering well-defined clarity and detail, without being too bright, harsh or sibilant. The airy extension creates a sense of additional space in terms of soundstage size. It’s easy to zone in on intricate nuances of detail with hi-hats, the furthest extremities of violin strings, cymbal crashes etc - and indeed with more layered and detailed examples of say ambient music, where there is a lot of focus on field recordings and the more minute level of detail.

Technical

As noted, the EA1000 is a nicely resolving set and produces admirable levels of detail retrieval across a very respectable sized stage, especially for the asking price. Imaging is portrayed within a stereo field, with good centrally located position for vocals or instruments in this region, which sound accurately represented. There is a good sense of space between instruments, without any sense of congestion for busier or more complex music. While not clinical, it is very easy to perceive individual elements of the music in the mix, yet of course still coherent. There is a good sense of depth in the stage, with layering creating a sense of proximity to various elements of the music being closer or further away, cymbals and hi-hats for example often reach out beyond my head left and right.



Test Tracks

Vince Clarke - Red Planet

A highlight album of 2023 for me, and one I have listened to many times over the last few months. This track actually a great example of one that sounds like it’s title, it has an otherworldly feel to it where it builds to a dramatic climax, creating a sense of wandering the red planet’s vast landscape - it is very emotionally captivating and the EA1000 does an excellent job of providing that sense of the vastness of that distant world of Mars, synths extend out to great distance and the more climatic moments sound dramatic but not harsh or congested, also demonstrating the dynamic capability of the set with fast transition from quiet to busier and ultimately louder moments.



Omni Trio - Sleeper

And now for something completely different - jumping straight to one of my favourite test genres for any IEM, some quality D&B (Drum & Bass) from the legendary Omni Trio - a huge favourite for me when out walking, I love the pace and complexity of the music, along with typically sweeping and emotive synths, deep cavernous sub bass, and fast-paced percussion. This sounds wonderful - the intermittent bass line that emerges every so often really drawing attention to the passive radiator at work, where it has that sub-woofer sensation. As the track progresses, and the drumming becomes even more complex, the EA1000 has no difficulty keeping up with the pace and driving every bit of detail - likewise ensuring the big sweeping synths swirl out to the furthest reaches of the stage, creating a highly immersive listening experience.

Side note: I really wish Omni Trio would reissue all back catalogue albiums to Bandcamp, I have their albums on CD but could do with better digital remasters!



Portico Quartet - Beyond Dialogue

A really beautiful blend of jazz and electronics from the excellent Portico Quartet, from the excellent album ‘Art in the Age of Automation’. I’m again immediately captivated by the sense of space, and overall clarity, positioning and dynamic range from the loudest to quietest moments. Instruments sound accurately portrayed, and again highly emotive and engaging. I have to point out again as I keep perceiving this - I love how the EA1000 presents the likes of hi-hats in a smooth, coherent way that pushes them out in a visceral way to the furthest edge of the stage - creating a wide stereo sound field. Bass doesn’t dig as deep as the previous track, but still has a sense of a sub-woofer presentation, albeit more subdued by the nature of the track.



Violeta Vicci - Autovia

The self-titled track to the brilliant ‘Autoviva’ from 2019. This again does an excellent job of demonstrating how the EA1000 copes with a ‘large’ sounding piece of music, one that needs to have the space to allows the synths, strings, and other electronic elements to flourish - again handling the dynamic range, the multiple layers, and balance across the FR to accurately represent what is ultimately a complex, subdued, yet dramatic and beautiful piece of music.



Abfahrt Hinwil - Radiowellen

This tracks features on the classic 'Links Berge Rechts Seen' album which was originally released on the legendary Toytronic label in 2002, but lovingly reissued by the also arguably now legendary Lapsus Records from Spain, they've been doing a sublime job of unearthing IDM classics from the past few decades and presenting them to the world again on vinyl. While not overly complex, there are multiple layers and a lot of intricate detail - the percussion has more of a mid bass focus with an offbeat kick-drum which presents wonderfully in the centre of the mix - the many layers of synths present with a beautiful melodic captivating tonality. This is another track I've heard countless times over the years since I originally picked up this album on CD in the early 00s, EA1000 doing a mighty fine job playing it to me again.



Autechre - VLetrmx

I'm probably being a bit indulgent here as I've started to think of tracks I've known and loved for many years that fit in the IDM theme, Autechre of course for those of you who know them are unquestionable legends of the genre, and on the scene now since the early 90s. This track is actually more ambient in reality as it is completely beatless, but instead builds on layers and layers of brooding, captivating synths up to an incredibly emotional climatic waves - this build in my experience requires that the set can maintain a composure as the 'drama' continues to unfold, taking care not to sound harsh or congested. Yet again, EA1000 does not disappoint, and I have an overwhelming desire to kick back and completely immerse myself in this utterly spectacular piece of music.



Still Corners - The Trip

Another album I've loved for many years, and this opening track a real favourite. It has a wonderful sense of melancholy, and I adore both the vocals and instrumental arrangement - the opening guitar has such a distinct and gripping intensity. Vocals sound accurate with good body and higher registers are free of sibilance - positioned perfectly centre and a touch forward, with guitars positioned to the left and right, percussion a touch behind and with good positioning with cymbals stretching out giving a great sense of space. A busy enough song, beautifully rendered on EA1000.



Comparisons

OD200 - more of a relaxed presentation and less resolving with a smaller stage, yet I’d class this as all part of the charm of the OD200, it’s the type of set that you can listen to for hours without fatigue. While they both have a nice emotive warmth, EA1000 sounds immediately more spacious with musical nuances far more apparent. OD200 focuses more on mid bass than sub, EA1000 extends deeper with that sub-woofer like experience, where the overall smooth tuning of the OD200 with that mid bass focus tends to result in an overall more intimate presentation.

Project M - at $329, this latest from Dita has created a lot of noise in the community in terms of what it offers from an overall package perspective for a relatively low price - having owned and recently reviewed a set, I can fully agree with the general community feedback so far. What you are getting here is a more neutral sounding set that focuses on clarity which when I switch from one to the other is immediately apparent, EA1000 strikes me as more emotive but steps back on clarity and detail. These offer different flavours really and I could easily see a case for owning both where you might want a more neutral reference style tuning. While EA1000 is a comfortable set to wear, Project M takes the prize here as possibly the most comfortable IEM I’ve ever worn, likewise the wonderfully ergonomic cable is a massive feat in itself. In addition to the more neutral tonality, Project M is also brighter up top, presumably due to the BAs handling the highest frequencies.

TS316 - a step up here in terms of resolution, with an immediately noticeable increase to details and soundstage, the depth of sub bass extension apparent too, and overall sounds more energetic due to a brighter tonality. The TS316 is an easy recommendation at $499, but no more so as the EA1000 at $219, both offering significant value in terms of their performance vs higher priced sets. While EA1000 sounds instantly enjoyable and captivating, TS316 jumps up to being instantly impressive and arguably one of the most competent single dynamic drivers in the sub $1K category.

Conclusion

It’s genuinely hard to say anything negative about this set - as noted in my sound impressions earlier, it’s an IEM that is just very easy to enjoy and in my experience works with any genre I care to reach for. Of course some will want more resolution, or a more exciting music portrayal - we all have our specific requirements in this hobby, but I do think safe to say an easy recommendation for anyone looking for a musical set which has admirable technical capability and offers an all-round ‘safe’ tuning. There are of course 'improvements' in various elements as you step up to sets at far higher price tags, but I would expect that, while at the same time taking the very real notion of diminishing returns into consideration. This is my first from Simgot and definitely exceeded expectations, I can fully understand why these have been so highly praised in the community for many months now, certainly not a 'fly by night' set with fleeting hype, these are in my opinion a real benchmark set in the price segement and above.

+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

Summary:
To summarize the review EA1000 Fermat from Simgot is a single dynamic driver IEM with a passive radiator, priced at $220. Considering the price packaging is nice and it comes with high quality accessories. Build is solid and the design is fantastic. With a bright mild V-shaped sound signature, the EA1000 provides quality bass, clear midrange, and refined treble. Despite minor drawbacks such as sub-bass quantity and a bit thin upper mids, the overall sound quality is quite enjoyable. Technical performance of this set is quite good as well.



Disclaimer: this unit was purchased with my own money and this review is my honest and unbiased opinion, thanks.

Intro
This is EA1000 Fermat from Simgot, this is a single dynamic driver iem with a passive radiator. This comes in at $220.
Talking about Simgot, they are a well reputed chifi brand. They gained quite a bit of popularity from their EA500. I have previously checked out their EW200, which is the best balanced sounding single DD iem under 50$ in my opinion. I am planning to check out their EA500lm soon. Anyways Getting back to the EA1000, these have been getting quite a bit of hype recently, and I must say these deserve the hype.

Build and Design
Let’s start with EA1000’s build, very solid
The shells are made of solid metal, aluminum I am guessing. The shells have nice weight to them, feels quite substantial in the hands. The shells are average sized. The face plate design is immaculate, it looks way more gorgeous in real life than any of its picture. The Simgot logo in on top of a patterned surface and it seems to be covered by glass giving it a 3d-ish look. Fingerprints or scratches can be an issue due to the polished finish, but its fine in my case. The 2 pin connector is recessed type. The nozzle is standard sized and also lipped thus it holds eartips quite securely. The shells are vented, so there is no pressure build up.



Fit and Comfort
Moving on to the fit and comfort section, it is good. The shells sit nice and flush in my regular sized ears. Breathability is good because of the vented design. Stability is ok, I did notice the iems slipping out sometimes but rarely, I am guessing because of its weight. I did not find any issues with long term listening, it was comfortable.

Cable
The EA1000 comes with a very nicely built stock cable considering the price. This is a 2 core silver plated copper (OFC) cable in litz structure. It uses a 0.78mm 2pin connector and terminates in 3.5mm. I wish the cable came with modular terminations. Connectors and the Y split are made of metal. There is no audible microphonics. Cable memory is basic, but a bit more softer cable would have been nice. The preformed earhooks are ok, they blend in with the color of the cable and did not cause any irritation. Cable weight and thickness is standard. In terms of looks this goes nicely with the white and silver theme.



Nozzles
The EA1000 comes with three sets of tuning nozzles. The difference between each nozzle is not very massive. Personally I used the silver with red silicone band one, I find this one most compatible with my taste.

Sound tonality
The EA1000s provides fantastic cohesion with a unique, clear tonal quality that highlights remarkable transparency. Despite their neutral sound signature, they stand out from many 'reference' tuned IEMs by avoiding any sense of dullness.

Bass
Let's delve into the bass performance of the EA1000, which is nearly flawless. Handled by a single dynamic driver along with a passive radiator, Simgot's choice of drivers deserves praise; you can truly sense the quality of the dynamic driver with every beat, delivering that classic dynamic punch. In terms of positioning, the sub-bass is subtly rolled off compared to the mid-bass. The sub-bass, thanks to the passive radiator, feels tactile, but a bit more quantity would be better. Mid-bass is more forward and it provides ample punch. Overall, the EA1000 has a fast and precise bass response, somewhat like planar bass. The body and layering are executed well, with instruments like the bass guitar and kick drums sounding accurate. Decay and reverberation are satisfactory, and bass note separation is solid. Personally, I did not find it to be bloated or muddy in any way. The only drawback I can think of is the sub-bass quantity.

Mids
Moving on to the midrange, the EA1000 prioritizes clarity and transparency. The transition from bass to lower mids is relatively linear, with minor and well-controlled bass bleed. Thus there's a hint of warmth in the lower mids, which contributes to the smoother male vocals. However, I've noticed that female vocals and the upper mids, in general, can sound a bit shouty and thin. While this doesn't get sibilant or harsh, it might be fatiguing for treble sensitive listeners. Nonetheless, I quite enjoyed the energy and intimacy present in the midrange. Note weight and separation are satisfactory. Instruments sound clean but is also slightly affected by the upper mid boost.



Treble
Transitioning to the treble section, Simgot has opted for a bright tuning for the EA1000, and I must say it's executed quite well. In short the EA1000's treble is refined, well-extended, and it flows nicely with the entire frequency range. Details are crisp without being too in your face. It is easy to spot intricate nuances. Occasionally, instruments sound metallic due to the boosted upper mids. While there is no significant harshness or sibilance issues, treble sensitive listeners may find it bothersome. The speed is normal to fast type. Personally, I find this tuning wuitw enjoyable with rock, metal, and electronic tracks. The airy presentation enhances the sense of space in the soundstage. This has good resolving capabilities.

Technical Sound:
Soundstage of the EA1000 is good, nothing extra ordinary. All three plains are above average, this has good width but the height is lacking. Stage depth is not bad.
Imaging is quite impressive. EA1000’s imaging is very accurate and its very easy to pin point instruments.
Sound separation and layering is surprisingly good
Resolution is solid considering its price and driver count.
Dynamics are good
Timbre is good



Conclusion
I have quite enjoyed my time with the EA1000 and I think this is worth the $220 price tag. Other reviewers are saying the new EA500lm is much better value, and I can’t say until I try that. But so far I can say for sure this is the best Simgot has to offer. If you like bright-ish mild v tuning definitely give this a try. Props to Simgot they did a awesome job with this one.
