Love Your Pocket – Jade Audio EA3 IEMs Review

Jade EA3 is made by a sub-base company of FiiO named Jade Audio, and they are priced at 40 USD. They will get compared with FiiO F9 PRO, Shozy Hibiki, and with REVONEXT QT3. Given their price point, they will mostly be paired with less expensive sources, or ultraportable DAPs like M6 from FiiO, so the pairing part will be combined in the build quality section of the review.


If you haven’t heard by FiiO yet, I really invite you to read some of my reviews about their products, because they’re one of those really awesome companies who does everything they can for their customers and helped shape the current audio world that we know. They are a large-ish company now and it is recommended to get their products from their official channels rather than directly from FiiO, unless you live in China, as your local sellers can serve you a bit better than FiiO can directly from China (since shipping a package will include taxes, shipping costs and all).

That being said, it should be noted that I have absolutely no affiliation with FiiO, I am not receiving any incentive for this review or to sweeten things out. I’d like to thank FiiO for providing the sample for this review, with me being responsible for paying the custom taxes. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in Jade Audio EA3 IEMs find their next music companion.

About me


First things first, let’s get the packaging out of the way:

EA3 does not come with much, just the IEMs and extra tips. FiiO usually has better packages, and it feels like the Jade sub company will save you some bucks on the package but still offer the same quality we’re used to seeing from FiiO.

Build Quality/Aesthetics/Fit/Comfort

The build quality is great, pretty plastic but pretty comfy. The body is large enough to fill most ears, but still not big enough to be uncomfortable for those with smaller ears. The cable is detachable, and of an excellent quality for the price point, which is 40 USD. The large dynamic driver is visible from the outside.

Happily, there is no driver flex with the EA3, FiiO managed to cut it out, with a vent, and there is no cable microphonic either. The default tips are not great in quality, and if possible, I would recommend upgrading to better tips, but they are nowhere near as bad as the default tips that most entry-level chifi iems come with, so it should be good to go, especially for the new audiophile who isn’t looking for Final Tips or Spinfit Tips in particular.

The term Chifi basically comes from the idea of Head-Fi and other headphone / earphone -related ideas ending in -fi, and Chi-Fi comes from Chinese-Fi, which applies to most Entry-Level earphones coming from China.

The drive factor is good, EA3 is medium to drive, not particularly sensitive to hiss, so it will work with any portable or ultraportable DAP, like FiiO M5, Shanling M2x, Hiby R3PRO, and even with DAC/AMPs like Lotoo Paw S1, Earstudio HUD100 or FiiO Q5s.

All in all, EA3 feels like a nicely built IEM, and although it is fully made of plastic, the design is original, and better than the alternatives from KZ which are always ripoffs after bigger, better products.

Sound Quality

Speaking of an IEM with a warm, and beginner-friendly signature, you can absolutely go for EA3 if you’re a fan of warmer signatures with a large bass, holographic and wide presentation, and if you like having a lot of impact. They are not very relaxing, since the midrange is quite uplifting and the treble is too, EA3 is a touch forward in general, and if you want something to relax to, FiiO has the darker-sounding F5. Most of their other IEMs, like the F9PRO, FH7, and FA9 are quite energetic. FH5 is borderline between being relaxing and being quite uplifting and energetic.

The bass of the EA3 is the central element of their sound, with a nice amount of body and impact. IT is a natural to slow timed bass, but it reaches very low, down to the 25 Hz range, which is excellent. The bass warms up the midrange, and it bleeds a bit in the mids, creating a feeling of warmth for the entire sound. There’s a good amount of detail and clarity with the EA3, as they are able to outline two or three basslines in complex tracks, but they are not quick enough for death metal and aggressive music.

The midrange is also pretty natural in speed, so they never come through as analytical, rather being pretty natural, pretty sweet and pretty musical. Indeed, where FiiO as a brand is known for fairly analytical and clear / somewhat bright and cold IEMs, it looks like the Jade sub-brand is going for warmer signatures. The soundstage is pretty wide, and not very deep, and EA3 has a pretty holographic presentation.

The treble is somewhat uplifted overall, enough so that the signature never feels dark, but not enough for me to call it traditionally V-Shaped. The treble has a fairly natural presentation, not a lot of grain, and if I was to complain about anything, I would have wanted a bit more sparkle. All in all, the signature is very versatile, works for classical as well as it works for rock and meal, but also for EDM and Pop.


The main competitor list for the Jade EA3 includes a ton of IEMs, since the Chifi producer market releases a new Chifi IEM every week, and not every one of them dies in a few months. I tried to pick a few important competitors, so I will be comparing the EA3 with FiiO F9PRO, Shozy Hibiki and Revonext QT3.

Pairing the Ea3 with smartphones like the Huawei P20, or Xiaomi Redmi Note 9s is a great ideea too, although most of the competitors generally ask for better sources, so if you’re wondering about pairing, Ea3 is simply not picky, which is why I skipped the pairing part of the review.

Jade EA3 vs FiiO F9PRO ( USD vs USD) – FiiO F9 PRO is quite a bit more expensive, but this doesn’t stop the EA3 from having some advantages over FiiO’s previous ace. Starting with the warmer sound, the sound also has a wider soundstage, and Ea3 is easier to drive and pair with DAPs and even smartphones, so it is much simpler to recommend, especially if you’re a beginner in Audio and want to see how a high-quality IEM sounds like.

Jade EA3 vs Shozy Hibiki MK II ( USD vs USD) – Hibiki is pretty cool by itself, but it lacks the package, and the detachable cable to be as cool as the Jade Ea 3. The sound also has better bass, and better low reach on the Ea3, and better treble extension, air and sparkle on the Ea3. Hibiki is more forward and even warmer than EA3, to the point where the sound is a bit fuzzy. All in all, Ea3 is more recommended in general than the Hibiki MKII in ever aspect, except for the plastic that touches your ear, which had a more comfortable finish there.

Jade EA3 vs Revonext QT3 ( USD vs USD) – QT3 is an unique case, because it has a lower end package, but it has a more detailed sound. It is more V-Shaped, and has a brighter treble, which may sound appealing at first, but that treble is quite shrill and metallic, in comparison to the more natural and less fatiguing treble of the EA3. All in all, if you want a super V-Shaped sounding IEM, you can go for QT3, but if you want something that’s warm, impactful and more comfy to listen to long-term, then EA3 is a better option.

Value and Conclusion

The value of the Jade EA3 is better than that of most Chifi IEMs, because the sound is really good, and they have a good build quality, along with an excellent comfort.

This being said, it is no news for FiiO to get the ergonomics right, and so far they had excellent ergonomics and build for every one of their IEMs, from the days of F9 all the way to FH7 and FA9 which have been released recently. No driver flex, paired with a nice cable makes it really easy to recommend the Jade EA3 more than the other options out there in the sub 50 USD price range.

The sound is warm, pleasant, it provides the listener with an impactful and uplifting presentation, but it doesn’t miss out on the treble, like Xelento did, and the sound also has a pretty wide and holographic presentation, making it easy to listen to the Jade EA3 regardless whether you enjoy rock, pop or electronic music.

At the end of this review, if you want a great IEM for 40 USD, if you’re looking for fairly good comfort, and if you don’t mind the plastic, if you want a good cable, along with a nice dynamic, punchy sound with a warm tint, the Jade EA3 is an awesome option and the IEM I can easily recommend you, even now, a few months after I posted the original Youtube Video Review.

Full Playlist used for this review

While we listened to considerably more songs than those named in this playlist, those are excellent for identifying certain aspects of the sound, like PRaT, Texturization, Detail, Resolution, Dynamics, Impact, and overall tonality. We recommend trying most of the songs from this playlist, especially if you’re searching for new most, most of them being rather catchy.

500+ Head-Fier
The Jade Audio EA3 is an in-ear monitor (IEM) utilizing a 13.6 mm dynamic driver and a Knowles 33518 balanced armature. It currently retails for $40. Jade Audio provided me with the EA3 in exchange for a fair and objective review.
This review is also available on my blog:

I have evaluated the Jade Audio EA3 with my JDS Labs The Element using local FLAC and Spotify Premium. Visit my page to get an idea of what I listen to.

The review package I received is likely not representative of the Jade Audio EA3’s retail packaging, as a sticker on the box slim white box reads “The product will probably be upgraded; pictures are for your reference only.” Inside the box are the IEMs, a detachable .78 mm 2-pin cable, a zippered cloth carry purse, and 12 pairs of silicone eartips in two different colors (S, M, L). The tips with red cores are slightly more conical in shape than the tips with black cores, which are more rounded in shape.

The Jade Audio EA3 has a high-quality resin housing with a mesh-covered metal nozzle. The nozzle has a substantial lip to secure the eartips. The faceplate has a dark smoky pattern set under the surface upon which the Jade Audio logo is set in metallic script. “L/R” indicators are printed in white adjacent to the 2-pin ports. The 2-pin connectors use a standard flush-fitting design but the IEM-side ports are raised slightly from the housing body. This creates an unsightly gap between the housing and the 2-pin connectors. There is a single circular vent on the inner face of the earpieces.

The 2-pin cable included with the EA3 has strain-relief above the straight 3.5mm jack housing and below the Y-split. The 3.5 mm jack and Y-split hardware are metal. The cable uses preformed clear plastic earguides and has a chin-adjustment slider. The oversized 2-pin connectors have raised markings to indicate left and right. My biggest issue with the cable is that the section below the Y-split is coiled rather than braided, which reduces its visual appeal to me.

The Jade Audio EA3 is intended to be worn cable-up. It has a shallow to moderate insertion depth. I did not find them to be comfortable even for short periods of wear. The nozzle angle is odd and the ergonomics of the inner housing body are poor. It was difficult to get a good seal with the included eartips. Secureness of fit is average. I experienced mild driver flex on one side.

My measurements were conducted with a Dayton iMM-6 microphone using a vinyl tubing coupler and a calibrated USB sound interface. The headphones are driven using my Element, which has an output impedance of no more than 1 ohm. The measurements use a compensation file derived from relating my raw measurements to published measurements from Crinacle and Antdroid. The measurements are presented with 1/24th smoothing. The magnitude of the valley around 7k is a coupler artifact. There is a resonant peak around 8k. Measurements above 10k are not reliable.

The Jade Audio EA3 has a V-shaped tuning that is on the bright side.

The EA3 emphasizes sub-bass over mid-bass. Sub-bass extension is very good but not best in class. Slam is moderate. When listening to bass-oriented music I found myself wishing for slightly more impact and weight to percussion. Bass articulation and speed are surprisingly good but bass texture is lacking.

The midrange has a thin, bright tonality. The limited mid-bass recedes sharply across the transition into the lower midrange, which avoids congestion and muddiness but also warmth to a large extent. Intelligibility is very good for both male and female vocals, though female vocals are slightly forward of male vocals. Instruments in the lower midrange are well-separated from male vocals. There is a bit too much presence and timbre is dry and plasticky. Female vocals sound parched.

The treble, while not quite harsh to my ears, is overemphasized and uneven. Cymbal hits are splashy and diffuse. Detail retrieval is excellent but there is a fatiguing amount of sparkle. Soundstage is quite wide and instrument separation is good. Imaging is lackluster in comparison.

The Jade Audio EA3 is easy to drive.

The Jade Audio EA3 is not competitive with the majority of IEMs at or below its price point I have had the opportunity to review in the last year.


100+ Head-Fier
Pros: Very wide soundstage
Amazing sub-bass extension
10/10 Comfort
Build Quality
Easy to drive
Attractive design
Authentic (certificates and other aspects are legit)
Cons: "lack" of mid-bass due to the greater sub-bass extension
Artificial and unnatural mids, vocals in specific
Needs long burn-in
Harsh out of the box (after burn in it stops being harsh, but is still a brighter sound signature)

EA3 is an IEM from the brand Jade Audio (a sub-brand of Fiio). EA3 features a hybrid setup: 1BA (Knowles 33518) + 1DD (13.6mm with polymer diaphragm).


This item has been sent to me through Jade Audio’s EA3 Review Tour, free of charge. I was required to write an honest review and not overstate the advantages. Everything said in this review is my opinion and how I feel about the EA3, I had no external/outside influence on my opinion.


EA3 features a stunning design.
You have to give them credit for the beautiful shell and smooth shape.
I just can't get enough of the shine off my black version.

If you was to catwalk for a fashion show, you could easily bring the EA3 and I can assure you that they wouldn't disappoint. I have the black version, which I prefer over the Weathet (blue) color, but it's all about personal preference. They are very stealthy and not in your face.

The Jade Audio logo underneath the shell gives a very bold, classy and serious look to it, this is mainly due to the beautiful cursive typography of the Jade Audio logo. The design of the EA3 can be compared to that of luxury and classic cars from 40's and 50's. Strong and sexy. The black finish looks even better than in the digital photos.

I like what Jade Audio did with the celluloid plate (it sits underneath the shell, it’s the part where the Jade Audio logo is placed on the IEM’s) because it features subtle shimmery/satin spots which mainly react differently according to the lighting.

You can probably conclude by now that Jade Audio, from a design point of view, absolutely nailed it with the EA3. Also not to forget, both the shells themselves and the housing of the 2-pin connectors are labelled for left and right, this makes connecting them the easiest part.


Build quality:

I have to say that overall, I'm quite satisfied with Jade Audio's job here. I didn't find any flaws or issues which would make me say that they have a bad build quality or feel cheapish. Yes, not all the fields in terms of build quality are spot on, but it might be too much to ask for from a sub $50 set of IEM's. What I can say, is that it's a solid and well built product.

Can we talk about the shell for a moment? It's as smooth as a babies bum. I think that mentioning that there are no sharp edges is a bit too obvious.
What is worthy of mentioning, is that it doesn't have any parts and points where your fingernails get stuck on, even in the part where the two parts of the shells are connecting, my fingernail glides over it.
The nozzles are angled and made of aluminum, the grills are also metal (they aren't going anywhere). The nozzle has a nice lip which makes sure your ear tips don't go anywhere.
Jade Audio definitely took the overall shell's build quality seriously.

The cable. This is the aspect which has me divided.

The build quality itself is pretty good, it features a metal housing for the 3.5mm jack, both the housing of the Y-spliter and chin slider are metal as well. And the little guy which many forget to mention, the cable tie. It is also very well done, it is soft.. but it seems like it likes everything around it so much that it gets caught on everything.

Then there are the clear plastic housings of the two pin (0.78mm) connectors. It would've been nicer and better if they were also metal, but even in this case, the plastic used is actually of high quality, not one of those muddy and cheapish plastics used on some cables. Both of the plastic housings are labeled for Left and Right. Not only this, but they are color coded too.. I don’t know for you, but for me this is a very handy feature. When you need to pick them up, you immediately know that blue goes into your left ear, red into your right. Good job here Jade Audio!

A problem which I solved my way (do at your own risk) the ear guides. They weren't uncomfortable from the beginning, but they were too twisted inside of themselves. I did it with caution, and made sure to hold the part of the cable closest to the housing (clear plastic part) with two fingers, making sure that this part doesn’t get bent (this is because you don’t want to disconnect and damage the connection inside). After I did this, the ear guide took an ear-shape, you can see this in my video review too.

Nothing spectacular here. A soft carrying case which doesn't feature any branding, and spare ear-tips.
I didn't find the case too useful and functional due to the pure nature and shape of the IEM's (this case would work for something like any of those earphones you get with your smartphone). I found myself using my hard case which did its job.

I found myself leaning towards the medium red tips, the black tips just made them even more harsh. The tips fit pretty well, and you have 6 pairs to pick from (S/M/L)




Did someone mention cozy?
These are simply 10/10 in terms of comfort. You can wear the EA3 for days, they simply melt inside your ears. When I have the EA3 in my ears, I forget they are even in. If that doesn't tell you enough about its comfort, I don't know what will. The comfort aspect is simply spot on, and I truly haven't found them uncomfortable at any point. You know when you are tired after work and just melt in your sofa? Mhm that's exactly how feel about the comfort aspect.

Functionality and convenience:

The EA3 is very functional, it truly is a great replacement for your daily drivers such as those earphones which come with your smartphone.

What do you do with your phones stock earphones? You watch videos, movies, play games and of course- listen to music, you basically do everything with them. In the same way, the EA3 is a great all-purpose IEM's which do all of those jobs fine, I wouldn't say that they are focused on one specific listening element or task.

The carrying case itself isn't too functional, but is a handy case for storing other sensitive objects or earphones. Both the cable tie and the chin slider are functional.

The IEM's themselves are easy to drive, both my Samsung S8 and Macbook Pro were able to drive them with no problem. With my S8 I can push them to around 50-68% before they become too loud and unbearable. With my Mac it's a different story. I listen to them at 2 bars when I'm listening to people speaking (video courses), and at around 5-6 bars when I'm listening to music. When I'm watching movies I also can turn them up to 5-6 bars.

If you travel and use your smartphone as the main source for listening, you may want to pay attention to this part. I found that if you are keeping your phone in your pocket and taking it out often, it's not very convenient. What do I mean by this? Simply the cable gets caught on the inside of the pockets (even with sweatpants). This creates a risk to damage the cable itself. The short and slim metal housing of the 3.5mm plug might be the cause. HOWEVER: if you absolutely are not a daily traveler who needs to take their phone out of their pockets every 5 minutes, this is nothing to worry about.


Sounds isolation:

Fantastic. Another element which Jade Audio got spot on. When I put these on (without music), I can barely hear somebody talking to me, when music is playing.. not a single word. I haven't tried them out in a busy public transport, however I did use them on bus and didn't find any trouble, very pleased with their sound isolation.

Sound leakage:
Even though the EA3 has two vent holes, it has pretty minimal sound leakage, which I am pleasantly surprised with. While I cannot provide you with accurate measurements, I hope you got the basic idea. Sound leakage will not represent a problem in public transport if you keep the volumes below 50%, however if you push them louder you will get some sound leakage which might present a problem in some places, at the end of the day you have to keep in mind that this is a pair of vented IEM’s.


Lows- Let me start this off by saying that these are sub-bass monsters. The sub-bass digs deep and rumbles.
EVEN at low volume it hits, this leaves me very satisfied with it. The sub-bass has both weight and rumble at low volumes.
However the issue is that the sub-bass is stronger than mid-bass. This creates an imbalance, which leaves me with the impression that the mid-bass lacks both weight and punch compared to the monster sub-bass which completely eats it. Sub-bass is more dominant, making it over-dominate mid-bass. The mid-bass is like a little kid compared to the sub-bass. Some people may misunderstood what I wrote above, by no means is the EA3 bass-light, and mid bass is completely fine, however if you are a basshead you will probably be left wanting more.
I found Hanz Zimmer's "Why so serious?" at mark 3:30 to be a very good test for sub-bass, the EA3 has plenty of it, I recommend you to give this track a try (shout out to Generic over at the "The Headphones Community" from whom I discovered this track's sub-bass)

Mids- This is an aspect which can definitely be worked on in the future. Mids sound very weird and funny.
Vocals are very boxy, and completely lack depth. It truly feels like the vocals are fixed in the nozzle of the IEM's. The thing is that only vocals are fixed, so while the instruments and other aspects of music have great depth, imaging, and dynamics, the vocals are kind of in your face. I was really able to separate the music by vocals and instrumental part, by this I mean that the "two layers" can be separated and noticed with ease. This being said, vocals don't sound natural, they appear to be "on top" and trapped in that space (which is fixed and separated from the rest). When music can be separated in layers, music doesn't sound unified, which isn't a good thing. As I mentioned in my video, they simply cut through the mix.

Besides the vocals, I found the EA3 reveling great detail and having great resolution. I truly noticed and heard elements in music which I never heard before. Suddenly music has more elements and you hear things in songs which you have never heard before, the micro detail which EA3 reveals is very enjoyable and a true different experience

Highs- There's not much needed to be said here, they are bright. I am treble sensitive and for me even at average levels they are piercing and harsh, however this is exactly why I loved them. Treble lovers will seek for this kind of a quality, however for me, not something which MY ears appreciate(d). In all honesty, because I am treble sensitive, I kept my volumes extremely low. I actually loved these IEM's because of their (at first harsh) treble, yes you heard that right- a treble sensitive person said it. I explained why in my video review.

Update: Now after they have been with me for over a month, I can say they lean to the brighter sound, however they are not harsh anymore and the treble has tamed down. I still enjoy and prefer to use the at lower volumes as though I don’t find any reason to push the volume louder, the main reason is the bass response from the 13.6 mm DD. I used to listen to extreme volumes jut to get “enough” bass, that’s not the case with the EA3 which broke my bad habit of extreme volume listening.


I was pleasantly surprised with the soundstage that EA3 offers. Vocals aside, it has both good depth and imaging. The soundstage is definitely above average and the spotlight of the EA3. I enjoyed watching movies with them, and I am sure these would be pretty handy for gaming as well, especially for games where space is important (Counter Strike: Global Offensive, Rainbow Six Siege...). The soundstage goes beyond the IEM's themselves, an this is one of the biggest pro's of the EA3. The soundstage jumps outside of the earpieces, and you are guaranteed to enjoy this new dimension to music.
I mentioned in my video review that these break the usual virtual space which is limited to the earphones themselves, EA3’s soundstage extends outside of the nozzle of the IEM’s in the same way an open-back headphone would (of course the soundstage of the EA3 and an open-back headphone cannot be compared for obvious reasons)



Overall Jade Audio EA3 is a superb for low level listening, a great all-purpose IEM and an IEM which will give another dimension to your music with either it's soundstage, sub-bass extension or the micro-detail revealing. I wouldn't say that these wouldn’t meet the high standards of audiophiles, however for someone who is looking for a high quality daily driver which has authentic certifications, information, these are for you. Many are too skeptical to jump into Chi-Fi and you can start with these, you will find the great options which are available in the Chi-Fi world. I am enjoying them quite a lot, and am beyond satisfied. They are a noticeable upgrade from your phone’s stock earphones, and they are very comfortable.

I hope you enjoyed the read and the content. Critics and feedback are welcome. I had a lot of fun and time invested into this whole review, I hope you enjoy it as much as I did making it. I think I said all the details and things I wanted to say. I am aware of some areas for improvement, I will be working on making my content even better the next time.




My Burn in process:
I proceeded to burn my EA3 by playing two playlists, from the start to the end with no pause. The volume was around 6-7 bars on my Macbook Pro (Early 2015).
The two playlists on Spotify (~22 hours):

And then I proceeded to make a playlist out of most of my music on my phone (~20 hours)

After this, I jut used them daily for watching videos, listening to music of course, and other tasks.

I do want to recommend another playlist which I haven't used but is definitely useful (100h and it also has silence, so you don't have to worry about damaging your device):
