AAW Black Malus Custom

Black Malus, made for your ears.

The same sixteen balanced armatures and 5-way crossover as Black Malus, 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 Epsilon cable.

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.

Drivers

Sixteen Armatures, Five Bands

Four of AAW’s own vented miniature armatures work as power woofers, giving the low end real extension and physical weight from a compact footprint, without clouding the midrange. Four more are given to the midrange alone, so voices keep their body when an arrangement fills up; two bridge the upper mids, and two shape the edges, the transients and the cues of space.

At the top, four super-high armatures sit in a 3D-printed manifold close to the eardrum, so their pressure is not lost down a long tube and the resonance of tubed designs falls away. A 5-way passive crossover holds each group to its band.

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.

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.

Questions

Good to know

How is Black Malus Custom different from Black Malus universal?

The fit and the look. The sixteen armatures, the 5-way crossover 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 stainless steel mid-case and a hand-poured opal faceplate, and fits with ear tips.

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?

Sixteen balanced armatures per side in five bands: four AAW vented power woofers for bass, four for the midrange, two for the upper mids, two for the highs and four super-high drivers, joined by a 5-way passive crossover.

Why are the super-high drivers close to the eardrum?

In a conventional design, the highest frequencies travel down a long tube and lose pressure on the way, picking up tube resonance. Black Malus places its four super-high armatures in a 3D-printed manifold near the eardrum, so the treble arrives without that loss.

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.
