Jade Audio JD3


100+ Head-Fier
FiiO JD3 - My first bullet experience
Pros: Very affordable price
Nice build
Good tone and timbre
Cons: Poor detail retrieval
Below average technicalities
Muddy lows
Veiled trebles (subjective)
Non detachable cables (subjective)

This is my second FiiO unit for review. Again I would like to thank my co-reviewer Adrian Yambao for lending these units. After 5 days of casual and critical listening, this is my impression. Pls do read on.



My opinions here are completely my own. I am NOT in any way influenced by any form of incentive. This is purely my honest, subjective impressions and experience with the gear on hand. I cannot stress more that you should take this as a grain of salt for we have different perception to sound and what we hear. I always try my best to stick with the stock accessories that come with the gear by default. You are free to try other methods such as tip rolling or cable rolling. Below are worth noting before concluding on what I say here:

1. DAP (digital audio player, be it phone, laptop, mobile, or stationary setup)
2. DAC or dongle or any external amp
3. Ear Tips
4. Cables
5. Source of audio file be it offline FLACS or streaming services like Deezer, Apple music, Tidal, Qobuz, Spotify and the likes..
6. Your playlist. It matters and is worth to be considered when reading from a reviewer's perspective. It is apparent that you get to know your favorite reviewer and what they are listening to leisurely and critically.

My reviews are more on how music sounds in my ears. The technical stuff like frequency graphs and the physics behind the tech and drivers used, I leave to other reviewers.


Configuration: 1DD 9.2mm
Impedance: 16ohms
Sensitivity: 107db
Freq response: 10hz - 40khz



Packaging comes with basic inclusions. As expected from a set at this price range.

1. Nice plastic transparent box
2. 3 pairs of silicon tips
3. JD3 itself, with attached cable.

Now let us dive into how JD3 sounds..


The lows, have good tone presentation, but let me tell you early on, it has a strong tendency to be muddy. I know this because I know my jazz tracks too well. The acoustic bass just sounds mushy and soft. And lacks details retrieval like string vibrations and fingerpicking. Sub bass is more prominent than the mid bass. Lows have good impact and weight but it is a bit too colored and elevated to my liking.

Conclusively, the lows turned me off with its muddiness. Lacks speed. Yet, tone and timbre is still commendable.


The mids lack energy and openness. Again details here are compromised. Somewhat veiled and more of this when we come in terms of the trebles later on. Again, tone and timbre is acceptable and organic. Mids have a bit of recessed nature but not too much to put a frown on my face. Vocals are good on both male and female.

Conclusively, tone and timbre is very desirable but lacks openness and details.


The first time I plugged this in my ears, I noticed the lack of air, openness of the trebles. Brass sections of my Earth wind and Fire lack that shoutiness and impact. This might suit treble sensitives but with the cost of details and energy on top. Cymbal strikes lack grit and bite. And a lot of micro details are compromised as well. This is the weak point of this set by far.

Conclusively, trebles here is my main complaints on how the sound is presented. The only thing that I can think of is this might suit treble sensitive individuals. Other than that, the treble did not appeal to me and I am quite disappointed.


Fit is very comfortable. Very lightweight given that the shells are made of metallic material. This is the first bullet type IEM that I reviewed and honestly it is a breath of fresh air for me. Ofcourse, the absence of ear hooks has its cons, but I find the fitting very stable and won't fall off your ears easily. Isolation is very nice too, surprisingly. Shuts off outside noise quite effectively. In terms of comfortability, JD3 is very comfortable. I once left it on my ears while napping for an hour, and it did not leave any physical pain.


Sound stage is somewhat narrow to my hearing. It did not give me a sense of good head space. There is nothing wrong with intimate staging. And honestly I enjoy both worlds, be it wide or intimate. Imaging is on the shady side of things. It seems that everything is pushed forward towards the center. Speed has a relaxed nature. Well I think it is because we are talking 20$ range here. In terms of technicalities, I did not expect too much from this price range.

And many more… I always listen to High resolution format, being the least quality 16bit/44khz FLACS be it offline or online.


For a 20$ priced gear, the JD3 is a decent set with a good tone. It just did not fall into my preference. Bass is too much for my taste, and has a tendency to be muddy because of its too relaxed nature. The mids were compromised due to the very noticeable veiled character of the trebles, which sacrificed a lot of details on top. The key points that will save this set are, the lack of energy on top will be suited to treble sensitives, and its comfortability of wear. Sadly, I don't think that I will recommend this. But yet, nice try FiiO for giving a very very affordable set that has a nice tone and timbre. Catch you on the next one! Cheers!!

Solid build quality
Cons: Bloated midbass
Blurry imaging

FiiO is a well-known brand from China that was established in 2007. The "Fi" in the brand name was derived from fidelity (as in Hi-Fi), and "iO" from 1 and 0 (digital signals). FiiO is one of the most versatile brands in the industry, offering a wide range of products including digital audio players, amplifiers, digital to analog converters, in-ear monitors and many more. The JD3 is one of their newest and most affordable offering, that currently retails for 20 USD. The Philippine circle of reviewers was provided by FiiO a unit of the JD3 for review purposes.

Unboxing and Accessories:
The JD3 comes in a rather simple but unique packaging. The box is made of clear, hard plastic with paper inlays for the brand logo, product name and other information. Upon opening, there is the earphone inserted in a thin molded black plastic sheet. Right below it is the instruction manual and four sizes of silicone eartips. The cable also comes with a velcro strap.

The shells are made of metal. The uniquely designed faceplates also act as a vent, and color coded to distinguish the left and right sides easily. The stem is made of rubber that also acts as a strain relief. On the left stem, there are three small bumps that can be used to know which side is which when in the dark. The nozzles are medium in length, and includes a fine metal mesh filter and a lip to lock eartips in position.

The cable is a very basic oxygen-free copper. Some minor microphonics is there but the cable is very light and the flexibility is great. It does come with a microphone module in a metal housing with three buttons for volume and play/pause. Also worth noting that FiiO does not offer a variant of the JD3 without a microphone. The splitter and gold plated 3.5 mm plug are also made of metal.

Now let's get to the sound.

The lows have moderate quickness but packs a heavy punch. Subbass is forward with sufficient depth, accompanied by an average length of decay. Midbass is also prominent. It is slightly bloated and can sometimes feel out of control; smearing nearby frequencies from time to time.

Overall, the JD3 has just adequate decay in the lows but the boominess is what really cements this as a basshead type of earphone. The midbass does get a little too excited sometimes though.

The mids take a small step back and have decent clarity. Upper and lower mids are equal in terms of position and both have thicker than average note weight. Instruments have fairly good definition, but vocals, on the other hand, have a tendency to sound a bit veiled or nasal.

Overall, I guess it's only fair to say that this section is the weakest point of the JD3. It can be good for laid back type of genres but whenever the vocals need to shine in a track, it does not receive the push and energy that it needs.

The highs are tight laid back just like the mids. Treble reach is below average that dissipates quite fast. Upper region has very little presence, resulting in some instruments to sound grainy. Lower treble also has a tendency to sound thin, causing some details to be easily lost.

Overall, with the current tuning, the highs get easily drowned out by the other frequencies. FiiO could have elevated the highs the compensate for the strong presence of the lows.

Soundstage and Imaging:
As expected, the stage does not have that much expansion. There is equal space in both the height and width. Imaging has acceptable transparency but can definitely feel lacking in genres like rock or metal. Layering and separation of instruments are just average, and congestion is definitely felt especially in complex tracks.

FiiO JD3 (1 DD, 20 USD) vs. Astrotec Vesna (1 DD, 20 USD)
The Vesna can reach deeper vibrations in the subbass and with a smoother texture, but the JD3 has a bit more rumble quantity. Decay is pretty much equal. Midbass definitely sounds heavier and more forward in the JD3. The Vesna has the clearer, cleaner mids. Vocals sound more airy and more upfront in the Vesna, instruments also have better definition in this section. The Vesna also has a lot more details in the highs. The Vesna also has better treble reach and has a slightly longer decay. Not much difference in the soundstage, only that it is slightly wider in the JH3. The clarity in the imaging is also better in the Vesna, by a mile. The Vesna also presents better layering and instrument separation.

Budget gears have been slowly but steadily improving over the years, with some of them not even sounding "budget" anymore. With the JD3, FiiO wanted to appeal to the masses by giving this gear powerful bass that may be good for some genres, but made the mistake of reducing the treble a bit too much that it gets easily lost in the background.

The best for the price
Pros: price quality difficult to Best.
Construction quality.
Sound in general, sound that is noticeable with a certain freedom is due to the semi-open design.
Good microphone.
Cons: For the price none, but already getting critical, it has a very annoying suction in the ear canal, the truth is that I prefer a ventilated design a thousand times, because I think it is quite harmful.

I believe that a review as such is not necessary for the following reasons in an extremely cheap product and there are plenty of reviews everywhere.If the pressure in the ear canal doesn't bother you, I highly recommend it. Thanks for reading and blessings to you and your family.

About Jade Audio

Jade Audio is a subsidiary brand of FiiO that was established in order to focus on the budget line so the parent company could use all their human resources in developing the main catalogue of their products.
The company is built around a team of core members who are subject experts with empirical knowledge in acoustics, focusing on the ultimate exploration of sound quality, with a commitment to independent research and development.
Jade Audio brand aims to create products with core functions and select accessories to provide audio enthusiasts with products of high quality at a competitive price.
The beginning was a little awkward with the release of a couple of discontinued FiiO products that got just rebranded.
It didn't take long to understand that this practice was leading to a dead end so they decided to get back to the drawing board and start designing from scratch.
Now Jade Audio has released three new products, two earphones and a DAC/amp dongle, the KA3 which strangely is also sold under the FiiO brand name.


The JD3 single dynamic driver iem

The JD3 has a 9.2mm dual-cavity driver that makes for excellent bass transient performance.
In addition there is a specially designed sound reflection-absorbing setup for the JD3, which helps to greatly reduce unwanted sound waves occurring inside the cavity with extremely minimal distortion.
It also features FiiO's patented system of balanced pressure relief between the front and rear cavities. The result is more natural sound, and more comfortable listening in longer sessions due to greatly minimized pressure on your eardrums when listening.
The JD3's driver employs a neodymium magnet with high
magnetic flux for ample energy reserves while the voice coil is
made of CCAW, which is lightweight and easy to drive.


Build quality and cable

Build quality is excellent and certainly much better than the humble price would suggest.
The compact, unibody shell is made from stainless steel with very good finish and a beautifully contemporary design.
The left and right earpieces are easily distinguishable thanks to the differently colored blue and red venting patterns.

The JD3 features a cable with line controls, allowing to place calls, control the playback of the music and adjust the volume.
The cable is of good quality with strain reliefs at all critical points and aluminum alloy plugs, it doesn't get tangled and has just a slight microphonic noise.


Wearing comfort

The JD3 is very compact and lightweight featuring the old classic, "bullet" like shape that is a rarity these days.
As expected the fit is snug, highly discreet and ultra comfortable, the JD3 disappears into the ear and after a while you forget that it is there, an excellent all day companion.
Due to the semi open design the noise isolation is good but not top notch nonetheless it gets the job done in a sufficient way and can be successfully used in noisy environments.



The JD3 comes bundled with four different sizes of silicone eartips and a small carrying pouch.


Listening impressions

With an impedance of 16Ω and a sensitivity of 107dB, the JD3 can be used straight out from your mobile phone jack but it is susceptible to noise.
Noise aside, don't let the humble price fool you as the JD3 can do a lot better and an entry level DAC/amp, like the ddHiFi TC35B or the Periodic Audio Rhodium that I mostly used for the evaluation, is highly recommended.
As per usual practice I left the JD3 playing music for 70-80 hours prior to listening tests.


The sound performance of the JD3 is phenomenal and punches well above the low asking price, in fact you are not going to believe your ears.
The tuning is very balanced, almost reference type, something very rare and unusual at this price point where almost everything sounds like a messed up mix of undefined sounds with generous amounts of boosted bass and treble.
The JD3 is playing some seriously good music, instead of just making a loud fuss to mask the environmental noise.
We are talking about an earphone that is not only suitable for the usual contemporary tunes but it can also be used for listening to more demanding genres like classical music.
Bass is mildly boosted starting from the lower end and gently downsloping to the mids.
Mid - bass is definitely colored but in a very gentle way resulting in a pleasant and warm tuning that is not too focused in this region nor clouds the rest of the frequencies.
Technicalities are held on a good level with quite tight and controlled response where bass sounds clear, textured and well defined.
Mids are a touch recessed when contrasted with the slightly accentuated treble but they don't lack in presence nor suffocate behind the lines.
On the contrary they sound spacious, clean and well defined with some fine texture and timbre.
Voices might sound a little under - projected but the clarity is exceptional for the price point and there isn't a single note missing from the mix.
As said above, the treble gets some extra highlight in order to compensate for the warmish tuning and add the necessary sparkle and the needed energy.
The JD3 is fast, not sluggish, with satisfying detail retrieval and while it might struggle a little when it comes to the higher frequencies timbre, which do sound somewhat metallic, it never ends in being too bright or harsh.
Interestingly enough the whole frequency band is presented with the same intensity and equal decaying characteristics, so the JD3 is perceived as coherent and homogeneous.
The soundstage is flat without any significant depth but on the other side it is quite spacious and open with precise imaging, a remarkable job at this price point.


In the end

The Jade Audio JD3 is a fun sounding but technically accomplished earphone.
With great sound, nice looks and excellent build quality it is a hell of an achievement that sets the new standards on price to performance ratio giving it a hard edge against the competition.
Honestly, for $20 this is a must have and every music enthusiast should own one.

Yes but my smartphone 3.5mm output is crappy so I always use at least an entry level USB dongle.
The JD3 might be cheap but it scales pretty good.
What smartphone of yours ? What about crappy recordings ?
Xiaomi Redmi Note 9 Pro very mediocre headphone output, I never use it.
The JD3 is forgiving and suitable for lesser material, it will not make your ears bleed.
If you can afford get yourself a ddhifii TC35.
