AAW ASH Custom

ASH, made for your ears.

The same seven-driver hybrid as ASH, in shells cast from your ear impressions: a deeper seal, more isolation and a fit you can wear through a whole set.

You design the shells and faceplates in the configurator, and it comes with our Tiburon cable.

Frequency response

Compare with other models

Measured by AAW on universal shells with one test setup. Custom shells carry the same tuning, though fit, tips and seal shift the result, above 8 kHz most of all.

Woofer

Thirteen Millimetres of Graphene

At the heart of ASH sits a 13 mm dynamic driver with a graphene diaphragm, which AAW calls an industry first: generous in size, yet thin on a nanometre scale. Its midrange is full, rich and textured, so AAW lets it carry the lower mids as well as the bass.

Beneath them lies a sub-bass that is powerful yet natural, of a kind no all-armature design can give.

Crossover

Four Ways, One Arrival

Six balanced armatures take over from the upper midrange: two for the mid-highs, four for the highest frequencies, for clear detail in the voice and treble. The treble extension is held in check, so the top stays easy over long sessions.

AAW’s TrueXross joins them without a high-order RC network, which can shift phase and scramble arrival times. A physical low-pass filter keeps the woofer to its own band, with minimal overlap with the armatures, and careful driver placement and a stainless steel acoustic bore bring the four ways to 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.

Tiburon Cable Included

ASH Custom comes with our Tiburon 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.

Elsewhere, post physical impressions from a local audiologist to Null Audio, #01-03, LHK2 Building, 76 Playfair Road, Singapore 367996, or email a 3D scan (STL) of your impressions or ear canals to support@null-audio.com. How to order custom IEMs explains what a good impression or scan needs.

Care

Caring for Custom IEMs

Clear the nozzles with the brush after use and wipe the shells with the dry cloth. Keep them in the case, away from heat and moisture, and avoid alcohol-based cleaners on the faceplates.

Pleasantly surprised

I have three sets of in-ear monitors none of which have deicent amount of bass response. I took a chance on the AAW ASH. I used them this Sunday in a live setting for bass monitoring. I couldn't believe the balanced response. From the highs, mids and lows. I could hear it all... finally.

AAW ASH

Very good.

Are these custom molded IEM and do you have my impressions on file?

Null Audio

Yes, it is ASH in custom version. Please send your order number (NAS7XXXX) to support@null-audio.com to check ear impression condition. Usually ear impressions are good to re-use within 6-8 months.

Questions

Good to know

How is ASH Custom different from ASH universal?

The fit and the look. Drivers, crossover and the Tiburon 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?

Seven drivers: a 13 mm graphene dynamic driver for the bass and lower midrange, two mid-high balanced armatures and four 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 ASH sound?

Tuned for listeners who love bass: powerful 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 Tiburon 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.
