Tuning

Four Voicings, One Switch

A small switch on the shell changes how the crossover loads the woofer and armature paths, so the whole voicing moves. No app, no cable to swap, no EQ.

Vocal brings the midrange forward for speech, worship and vocal monitors. Normal is the balanced reference. Vocal+ adds presence and articulation without sharpness. Bass gives the woofer more weight.

Drivers

NOVA Up Front, Graphene Down Low

Each driver has its own band. AAW’s NOVA open-vented armature sits deep in the nozzle, close to your eardrum, which removes the pressure loss and tube resonance of a conventional tubed armature. It carries the voice and the treble.

A precision armature fills the upper mids, and the 10 mm graphene woofer, thin and rigid, is filtered to the low band for natural sub-bass and punch. A 3-way passive and acoustic crossover keeps the handoffs in time and in phase.

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.

Epsilon Cable Included

A3H+ LUX Custom comes with our Epsilon cable with 2-pin connectors. Choose the player plug in the configurator: 2.5 mm or 4.4 mm balanced, or 3.5 mm single-ended.

You can also upgrade to a higher-tier Null Audio cable when you order.

A3H+ Lux CIEM

I had a chance to demo the unit along with some of their other offerings at their office, and the A3H+ Lux was the best sound quality to price for me.
I got my impressions done in their office, which was very quick and easy.
They took about 9 weeks from purchase date to when I got them at my doorstep in the US. (~8 weeks to make, then 5 days to ship to my doorstep)
I use them in a live stage setting, and the fit and seal of a custom mold made it a much better experience compared to my universals in ear monitors.
Having the ability to change sound signatures with the small switches on the IEM was a big positive.
I got the carbon fiber faceplates and they look great!
Overall, these are great CIEMs for those who are just getting into custom in ears monitors, and can't set aside the budget for the larger name brands or the higher end models from AAW.

Hidden Gems

A3H+ Lux CIEM was an excellent choice in that price range. These are hidden gems, and can out perform some of the well know brands. The custom shell and fit took approximately 8 weeks to complete, and around 4 days to receive in the USA.
The A3H+ Lux sound can bounce between 'neutral/cold' and 'neutral/warm' depending on the media you are listening to. It has an impressive low end, crisp vocals/mids and highs. All detailed and articulate.
The bass is punchy with emphasis on the mid bass as opposed to Sub Bass/Deep Bass (IMO). The bass hits nicely and powerful. it's crisp and accentuates the track without mudding the mids or vocals.
The soundstage is airy and a bit narrow, which for me is perfect. I find that too much air can result in a hollow sounding experience with some distortion. The vocals are clear and detailed. I would say that the
A3H+ Lux has a V shaped sound signature, balanced and accurate.
These have a spectacular three-dimensional sense of separation. Meaning... you can hear every instrument being played as it moves all around you while separate from the mids/vocals.
The A3H+ Lux also comes with 4 signature sound settings that you can adjust to your liking. (Vocal, Normal, Vocal +, and Bass)
*This IEM does not do well with bass boosted tracks. If you prefer majority of bass boosted music, these aren't the ears for you.
The A3H+ Lux is a versatile IEM.. meaning - (depending on your DAPs power/ and settings) you can tweak the vocals by moving them to the front of the soundstage or bring the vocals to the middle of the soundstage and let the music encase the vocals.
*CONS -
SubBass /Mid Bass is great, but I wish they would hit a little harder in the deep bass range. I have yet to find an IEM that can successfully pull it off.
A side note to AAW- please make an IEM that can render rumbling Deep bass while maintaining that wonderful upper/mids/vocal clarity.

Amazing designs and sound quality

There are a lot of designs to choose from and it makes it so easy to customize to one that you like. On top of that, there are 4 different eq settings for your perusal. Sound quality is amazing. Fitting is perfect.

A3H+ ciem

Perfect fit, with a clear shell.
It's look great.

Everything I was looking for

Affordable pricing, amazing fit and great sound. I chose the wooden face plates and they look beautiful. Thank you so much!

Very pleased

Great craftsmanship, I own other IEMs and AAWs are at the top as far as precision and build is concerned. Middle and high frequencies are slightly more pronounced, so EQ needs to be applied for my taste other people may prefer it the way they are. All in all great value for money.

A3H Pro

Just got mine yesterday. Perfect fit and really PRO sound. Seems that I got a free update to the ETHOS 5N cable as well. Don't know if the A3H Pro comes with this cable all the time or I was just lucky. Anyway, good product, worth the price and the wait.

AAW A3H+ Triple Driver Hybrid Custom In-Ear Monitor

Ordered it and did my ear impressions at the store. Item was slightly delayed due to CNY holiday but it came in a nice package with accessories.
Had to send one side of the IEM for a refit and retuning, hopeful everything will turn out well when I get it back.

Best of both worlds

A3H offers the best balance in terms of frequency response , awesome clarity without being harsh. It's very musical and engaging. It's finely tuned as a very resolving stage monitor. Would highly recommend it to any professional looking for the best sound and texture. I've compared it to much more expensive and fancy IEM and A3H scores higher for it's perfectly balanced sound that's not artificial or metallic like most BA based models, at any price range. Solid 5 stars for this outstanding monitor!

prompt

Nice workmanship

Awesome IEMs

Used it for the last 3 years; wonderful for both on stage monitoring and off stage casual listening. Love them!

Well built

Good soun but lacks a little bass

Review A3H ciem

The customs are fantastic. Superb sound quality with not much to complain about. However, customer service needs work. I've messaged a few times about sound unbalance issue and requested for alternatives if I cannot make it down to the store after work. No response on that.

AAW A3H

Great CS support and fit! First pair of CIEMs, and it was definitely a smooth transition into the world of CIEMs

Helpful and responsive

The staff are helpful and responsive towards our queries.

Fantastic product

Thanks for the quality products! This is the first pair of IEM’s I have used, but the sound quality is amazing and they fit perfect. You all did a great job both in making them and keeping me updated with the order progress. Have a great new year! Best Regards, Adam.

value for money

good CIEM, fitting and value for money. highly recommend for entry level user.

A3h CIEM

In all its a pretty well balanced sound, good clarity, although the high mids are slightly coloured and not "sterile".
Good fit, the customer service is smooth and all in all a great product

AAW A3H CIEM

Overall sound is good, much better than the IEM I was using before (shure se215). Noise isolation and fit of the CIEM is good. Recommended for starting CIEM

AH3 Triple Driver Hybrid CIEM

It perfectly fits in my ear loop. Noise cancel was perfect. The sound was great. Worth waiting.

A3H

Purchased for Massdrop Plus IEM The cable itself is great. Good build quality and it makes my IEM??s sound even better than the stock cable. My only complaint is that i wish the volume buttons were a bit bigger for me to tell the difference between them and the pause button.

AH3

Superb fit for the custom in-ear. It feels do comfortable. Sound quality is damn good.

Excellent service

Staff was willing to refit for me. They are very friendly and professional.

Purchase of A3H V2 Pro

Took awhile for the CIEM to be ready. Stock cable that comes along does not seem to be able to bring out the max potential of this CIEM. Will be getting an upgrade cable with Null Audio!

Questions

Good to know

How is A3H+ LUX Custom different from A3H+ LUX universal?

The fit and the look. Drivers, the four-mode switch and the Epsilon 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 has a CNC aluminium shell, 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 does the tuning switch do?

It changes how the crossover loads the woofer and armature paths, giving four voicings on one monitor: Vocal for speech, worship and vocal monitoring; Normal as the balanced reference; Vocal+ for more presence and articulation; Bass for a fuller low end. The graph above shows all four.

Which cable does it come with?

Our Epsilon 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.
