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.

Design

Made Your Way

Choose the shell and faceplate colour for each side, wood, glitter, foil or Atelier faceplates or your own artwork, the nozzle tips, the AAW logo finish and engraving, and watch it come together in the configurator’s live 3D preview.

Choose a recessed or flat 2-pin socket. The photos show finishes from AAW custom IEMs.

Lune Cable Included

AXH CIEM

Good quality and affordable 5-driver hybrid custom made earphone. Recommended to people who want to try how CM feels like.

AXH great CIEM

Upgraded from my CIEM A3H Pro, I'm very satisfied with my AXH.
The fit is great and they seem to be robust
About the sound, I would say it's neutral, with a litlle warmish side, due to the bass rumble ans the impact of the dynamic driver. The highs are smooth and non agressives. The soudstage is also great.
According to me, this CIEM paire well with detailled and neutral DAPs.

Custom Earpieces

A while to get used to customs. Only one brand - AAW.

Sounds different from what I auditioned, but still great.

I believe I may have auditioned a pair which had the original treble focused signature (also noticed by another user on reddit). I actually liked the treble signature. The new signature is more neutral which isn’t a bad thing, but the Lune cable included does not follow in the same spirit.

With the Lune mk5 cable, lows and highs are elevated, making the mids and vocals sound slightly recessed. The weight of Lune cable also tugs at your ears while you walk which is annoying. With the Arete cable, it brings everything to a neutral position, making AXH a lot more listenable and enjoyable at all volume levels. I’m starting to enjoy the new AXH with Arete and I suggest all to try out the different cables to see which suits your preference. :)

Worksmanship of AAW is impeccable. My CIEMs came looking great, but suffered from a poor fit probably due to the impressions, but there is a good refit policy to support so that’s fine.

Colourful cables

I hope in the future, AAW allows the customers to even custom design their cables. So far in the market the cables are pretty boring (black, silver, bronze. ...)
I believe colourful cables will bring something fresh into these market.

Okay, but not great for the price.

I've had these AXH CIEM's for over a month now so I have a feel for them. Two of my band members bought CIEM's from the US and I thought I would follow suit; but I chose AAW because I thought their 'Dynamic Driver' technology was more advanced and better suited to my listening style (Website quote: "AXH is tuned with a balanced sound signature in mind, it offers controlled yet natural sub bass which you will never find in a full balanced armature setup"). and they were described as being 'tuned' flatter plus they came with the Lune Mk5 cable.
The build quality is very high and the Lune Mk5 cable is very good. Some have said it's heavy, but I personally don't think so. Separate to the product quality, the fit of my in-ears into my ears seems a touch loose. I suspect it's because AAW took so long (11 weeks all up) to use my in-ear moulds that they shrank (dehydrated, dried up).
I play bass in a band; don't buy these in-ear's if you want to use them professionally on stage as a bass player. They get a pass mark as being adequate, but not great! I also do long motorbike rides and I listen to primarily rock music during those rides. Clarity is excellent but they are harsh in the top frequencies. I also bought a Capri USB-C cable with an in-line Hi-Res DAC to plug into my HTC U12+. The volume is only adequately loud enough. When I ride, I plug the Lune Mk5 3.5mm cable into a FIIO BTR-3 Hi-Fi amp and bluetooth it to my HTC. This works very well with very high volume and excellent clarity, but the AXH's are always harsh at high volume.
I am able to compare the AXH directly with Shure SE535 and HTC's generic supplied ear buds. AXH is easily the clearest sound but overall I can't pick the winner when plugged into my HTC and they are not worth SGD$550 more than the HTC ear buds which understandably sound really good in an HTC phone. BTW, I'm only comparing sound quality here, nothing else.
AAW have a 30 day or sometimes 60 day refit policy. You need to read the fine pri...

Questions

Good to know

How is AXH Custom different from AXH universal?

The fit and the look. Drivers, crossover and the Lune cable are the same. The custom is made from your ear impressions, so it seals deeper and isolates more, and you design its shells and faceplates. The universal fits with ear tips and is in stock.

How do I order?

Choose your options in the configurator on this page, then get ear impressions made. In Singapore we take impressions at our Playfair Road studio for SGD 50, by appointment. From overseas, post physical impressions or send us 3D scans (STL files) of your ear impressions or ear canals.

How to order custom IEMs

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.

Which cable does it come with?

Our Lune cable, with the player plug you choose in the configurator. You can upgrade to a higher-tier Null Audio cable when you order; see the AAW cable guide.

How long does it take?

6–8 weeks from the day we receive your ear impressions or scan, plus shipping.

What if the fit isn’t right?

We refit it for free within 30 days of delivery. For overseas orders, return shipping is charged separately.

What warranty and returns apply?

One year against defects in materials and workmanship, on the monitors and the cable. Custom IEMs are made to your ears, so they can’t be returned for a change of mind; quality problems are covered by the warranty.
