AAW Canary Pro Custom
The same fourteen drivers as Canary Pro, in shells cast from your ear impressions: a deeper seal, more isolation on stage and a fit you can wear through a whole set.
You design the shells and faceplates in the configurator, and it comes with our Lune cable.

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.

Electrostatic
Each of the four electrostatic super tweeters is a gold-plated membrane weighing six micrograms, held against a plate charged to as much as 400 volts. A miniature transformer built into the earpiece raises the signal up to a hundredfold, and the music itself draws and releases the membrane to make sound.
No energiser, no separate amplifier: plug Canary Pro into your player and it is ready.

Woofer
Two dynamic drivers work as an isobaric pair, doubling the effective diaphragm area without enlarging the shell, for low-end pressure with cleaner control of excursion. They have a 3D-printed acoustic chamber of their own, which reshapes their character.
AAW calls the whole the Extreme Multi-Driver Matrix: fourteen drivers, with a 5-way passive crossover keeping each in its own range, so the dynamic and armature drivers meet with as little phase shift and interference as possible.
Design
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.
In the box
Canary Pro Custom comes with our Lune 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.

Process
Fit
In Singapore, we take ear impressions at our studio for SGD 50, by appointment through WhatsApp +65 8731 5476 or sales@null-audio.com.
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
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.
If the fit isn’t right within 30 days of delivery, we refit them for free (overseas return shipping is charged separately).

Questions
The fit and the look. Drivers, the flat 7 Ω impedance 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 has a natural pearl faceplate, fits with ear tips and is in stock.
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.
Fourteen drivers per side in three kinds: two dynamic woofers in an isobaric pair, eight balanced armatures (two low-range, two midrange, four mid-high) and four electrostatic super tweeters, joined by a 5-way passive crossover.
Armature drivers usually make an earphone’s impedance rise and fall with frequency, so its sound depends on the output impedance of the source. Canary Pro changes the character of its armatures from inductive to resistive and holds a flat 7 Ω across the range, so it sounds the same from one source to the next. A clean source with low output impedance suits it best.
No. A miniature transformer inside each earpiece raises the signal for the electrostatic tweeters, so Canary Pro plugs straight into a portable player, a dongle, a DAP or a desktop amplifier.
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.
8 weeks from the day we receive your ear impressions or scan, plus shipping.
We refit it for free within 30 days of delivery. For overseas orders, return shipping is charged separately.
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.
