AAW Kingfisher
Kingfisher is AAW’s tri-hybrid for gaming: the same three drivers as ACH, a dynamic woofer, a NOVA open-vented armature and AAW’s ceramic super tweeter, on a cable with a detachable boom microphone.
It follows the acclaimed Canary in its three-tier design, with a ceramic tweeter where Canary has an electrostatic one.

Ceramic super tweeter · detachable boom microphone · Ethos gaming cable
Microphone
Kingfisher’s cable carries a boom microphone on a detachable MMCX joint, with a sensitive 11 mm condenser capsule: a clear voice in every call, and good enough for recording and mixing.
Unclip the boom and it is an in-ear monitor for music like any other.

Tweeter
The treble comes from AAW’s own ceramic super tweeter: a piezoelectric membrane built up in seven layers, the first of its kind. It is laser-welded directly onto the dynamic woofer’s housing, so the two form a single coaxial unit, rigid and free of stray vibration.
Beside it, AAW’s NOVA open-vented armature sits deep in the stainless steel nozzle, close to your eardrum, which removes the pressure loss and tube resonance of a conventional tubed armature.

Faceplates
The faceplates are held by hex screws and can be swapped by hand. Other faceplate designs are available, and so are faceplates made to your own design.
In the box
The cable is our Ethos gaming cable: multi-stranded UPOCC copper with silver plating, quad-braided, ultra-flexible and light, so it stays out of mind when the focus is on the game. It plugs into detachable 0.78 mm 2-pin sockets.

Three drivers in three tiers: a 10 mm dynamic woofer for the bass, a NOVA open-vented armature in the nozzle for the mids and highs, and AAW’s 7-layer ceramic super tweeter, laser-welded onto the woofer’s housing as one coaxial unit. A 3-way passive crossover joins them.
A piezoelectric tweeter: a thin ceramic membrane, here in seven layers, that flexes when the signal is applied to it. AAW uses it in ACH and Kingfisher as a more affordable relative of the electrostatic tweeter in Canary.
Yes. The boom attaches to the cable with an MMCX joint and comes off, leaving an in-ear monitor for music.
