AAW AXH

Even-handed, from the bass up.

AXH is AAW’s five-driver hybrid: a 10 mm dynamic woofer for the low end and four balanced armatures above it, joined by the same 4-way TrueXross crossover as ASH.

Where ASH leans into the bass, AXH keeps the balance. Its sub-bass is controlled and natural, the voice and treble are clear, and the top is smooth enough to listen for hours.

Drivers

Five Drivers, Evenly Weighed

A 10 mm dynamic driver takes the low end, and four balanced armatures sit above it: two for the mid-highs and two dedicated super-high armatures for clear detail in the voice and treble.

The tuning is balanced. Sub-bass is controlled yet natural, of a kind no all-armature design can give, and the treble extension is held in check so the top stays easy over long sessions.

Crossover

Four Ways, One Arrival

AAW’s TrueXross joins the drivers without a high-order RC network, which can shift phase and scramble arrival times. The dynamic driver’s diaphragm is individually tuned, and a physical low-pass filter keeps it to its own band, with minimal overlap with the armatures.

Careful driver placement and a stainless steel acoustic bore do the rest, for better coherence, less phase shift and the four ways reaching the ear together.

Lune Cable Included

AXH comes with our Lune cable, 1.2 m long with 0.78 mm 2-pin connectors. Choose the player plug when you order: 2.5 mm or 4.4 mm balanced, or 3.5 mm single-ended.

The sockets are standard 2-pin, so AXH also takes any of our 2-pin upgrade cables.

Great sound

Great Workmanship & Nice Sound

Treble：clear and comfortable, better than my last UE TF10
Mid：I think it's AXH's selling point. Leaning forward and smooth. TF10 hid the mid and now they spring out beautifully.
Bass：A little thin and doesn't go deep, but still has its quality. Perhaps it would be better after changing the cable to a UPOCC.

Overall：5 STARS for pops, jazz, classic and ACG, but 4 STARS for rocks, heavy metal.The separation is excellent and sound stage is 3D-like (with 4.4 balanced FOB&my WM1Z). This is a gorgeous IEM with high cost-performance ratio and workmanship.If you like crystal treble and mid then it won't let you down~

Great earphones!

These are the best earphones I have tried in the last ten years. Sound is crispy clear, lots of detail. Bass is fine but could be improved.

AAW AXH and Null Cable Lune Series 4.4 balance

First time I bought from this company and it was a very good experience! The products are top of the line and exceeded my expectations! Always using my AXH and Lume series combination everywhere I go. I will recommend this company to my co audiophile people as well as my Friends. Keep up the good work and looking forward to make business with you again folks!
Happy Holidays!

Great sound !!!

Neutral and comfortable hybrid iem

For me AAW AXH is a good implementation of hybrid iem which plays very relaxed and neutral sound: in 2019 version I didn't hear any mid-hi peaks other users were writing about, at least this is true for my Yulong Aquila and Chord Mojo, although this neutrality, silky mids and deep, layered but rather soft bass may not appeal to some (sometimes - even myself included), so if you want more aggressive sound then I suggest to check other AAW models as well before you buy (e.g. ASH sounded a much more detailed to me). Isolation of universal model is good - of course it's worse than custom, but it blocks most of the external noises when music is playing, so this is a good choice for commuting.

AXH + lune/ tiburon

Quite enjoyable earphones, dynamic driver knows its place and don’t even try to crawl on mid frequencies. Sometimes axh is a little bit sparkle cus of the peak on 5kHz. In my opinion dat peak is the only one drawback :(
Thats why I bought Tiburon copper cable which makes them much more warmer.

Best midrange

I revice the iem two week ago first I break in for two days the sound very smooth but need more bass if use the phone amp more better sound field really 3D
Suggestion this iem if your iem use phone amp the result will increase 15-20%

AXH UEM

Very lively sound not warm like normal BA types.

Great sound stage comparable to Westone W60 but at half the price

CHEATERS - Poor product, poor service, didnot come with all accessories

I ordered B-stock ASH & AXH IEMs at 30% discount, which has an MSRP of USD 799 & USD 449 respectively.

1.) While switching the ear tips on the very first day, the stainless mesh on ASH came out. Instead of replacing the IEM piece, they initially offered sending a few stainless meshes, which never arrived.
2.) During A-B comparison, I was astonished to find that there was "absolutely no difference" in the soundstage of ASH (13mm Graphene Driver + 6 x Balanced Armature Driver with Symphonym Tiburon Cable) and AXH (10mm Dynamic Driver + 4 x Balanced Armature Driver with Null Audio Lune Series Detachable Cable).
3.) I then compared with my 20 years old $100 Sony MDR-7506. Apart from lower volume due to higher (63) impedance, again there was no difference.
4.) To be completely unbiased & rule out issues with my hearings, I did blind test with my two daughters. They both have undergone over a decade of Classical Vocal training, play flute, keyboard, and listen to various genre of music like Jazz, Hip hop, K-Pop, Pop, Blues, Rock, Symphonies, etc. Even they couldn't find any significant difference among the 3 IEMs/ headphones.
5.) When I requested to return one of the IEMs, they refused to accept returns inspite of their 14 days return policy.
6.) The 2 IEMs did not come with the Flight or 1/4" adapter, as it is mentioned on their site. When I asked for it, they politely agreed but never fulfilled their promise inspite of 4-5 reminders.

I definitely Do Not recommend their product or their service. Just a bunch of liars & sweet talkers.

It is explicitly stated on the B stock sales page All sales are final, no return or exchange is accepted.
We are sorry to hear that you could not hear any difference between the multiple IEM and headphones, however, that is not our problem.

Genuine sound guality

These earphones are best choice in 300-500$ price range. Outstanding sound quality, emotional and with its own signature. Definitely worth its price!👏🏻🤞🏻👍🏻

Poor isolation

The canal section is very short and doesn't go in deep enough. Even with large comply foam tips it tends to slide out, is not a snug fit, and isolation is poor. (My usual tip size is medium if the earphones fit well.)

Wonderful product with very reasonable price

It is a naturally sounded IEM with nice emphasised bass. The bass performance is both qualitative and quantitative. For the mids, the voice of the signers are well situated, not too close to the ear, but very clear. With the stock cable, the overall resolving power of this IEM is very high, however, the sound is a bit thin, but I think this could be improved by changing the stock cable with occ cables.

Natural but abit thin sound

Overall, it is a satisfactory IEM, the sound signature is quite natural with nice bass reproduction. The mids and highs are quite resolving, but with the stock cable or occ based cables, the sound is abit thin comparing to other competitors. But I need to point out that at its price range, it is a very satisfying IEM.

Good sound!

Superb sound for value. I'm very happy!

Order was easy and delivery no frills!

心地よい高音域

4BAドライバーの音の繋がりが非常に良くできていて、高音域の心地よさが素晴らしいです。
これだけだとカリカリなモニターサウンドみたいな音になってしまうんでしょうが、ここに一発搭載されているDドライバーが絶妙にマッチしています

AXH Universal

I ordered the AXH Universal Fit IEMs, and after a few weeks of listening can say that I am happy with my purchase. As this is my first pair of hybrid IEMs it is difficult for me to compare them with others. However, I can tell that even though there is a V shape tuning, it is subtle enough to allow for listening to a variety of audio/music (ie. adequate bass without sacrificing clarity in vocals, etc). The largest tips even fit my cavernous ear canals better than I expected. I wish that they would have come with a more compact but study carrying case. The one it shipped in is good for storage or touring, but too large for very portable use. Overall, I am very happy with these!

AXH Universal In-Ear Monitor

Thank you and well received.

Another excellent product

These earphones have a punchy base like I was need. Breaking not permitted but up to now the match with Astell Kann is satisfying for my need.

Very musical and neutral sounding.

Got these during the CNY year deal. Great quality!

AAW AXH UIEM - Excellent Product

High quality product for a reasonable price when compared to other IEMs. Packaging is very classy. The sound quality is well balanced and natural from the bass to the highs. The only downside is that the supplied audio cable is a tad short. You would need an extension if you're a musician and require the IEM to be connected to a wired sound monitoring system.

Good sound!

Questions

Good to know

What is the driver configuration?

Five drivers: a 10 mm dynamic driver for the bass, two mid-high balanced armatures and two super-high balanced armatures, joined by AAW’s 4-way TrueXross crossover.

What is TrueXross?

AAW’s crossover for hybrid monitors. Instead of a high-order RC network, which can shift phase and scramble arrival times, a physical low-pass filter keeps the dynamic driver to its own band, with minimal overlap with the armatures. With careful driver placement and the acoustic bore design, the result is better coherence and timing between the drivers.

How does AXH sound?

Balanced: controlled yet natural sub-bass, clear detail in the voice and treble, and a controlled top end that stays easy over long sessions, with a stage AAW likens to a pair of full-size headphones. The graph above shows its response.

Who is AXH for?

Musicians in a band, emerging artists and worship teams, and anyone who wants a balanced hybrid with a natural low end and clear detail in the voice and treble.

Which cable fits AXH?

AXH has 0.78 mm 2-pin sockets. Choose Standard 2-pin (0.78 mm) on any of our cables; see the AAW cable guide.

Is there a custom version of AXH?

Yes. AXH Custom has the same five drivers in shells made from your ear impressions; see how to order custom IEMs.

What warranty and returns apply?

AXH has a 1-year warranty on the monitors and the cable. Unused universal IEMs in their original packaging can be returned within 14 days of confirmed delivery, with a 30% restocking fee. See shipping and returns.

Do you ship worldwide?

Yes. Most countries get free shipping by EPAC, and FedEx Priority is free on orders of USD 250 or more. In Singapore you can also pick up from our studio at 76 Playfair Road.
