W900 Custom In-Ear Monitor & Capri Balanced Lightning Audio Cable

 W900: World's First 9 Driver Hybrid CIEM

Developed and enhanced based on our acclaimed hybrid system, W900 is at the summit of our ideology of fusing the best traits out of dynamic and balanced armature drivers. Instead of creating high order RC crossover network, which usually causes chaotic phase shift and scrambled arrival timing, AAW uses a complete new approach called TrueXross to solve the classic coherence issue in hybrid earphones. The dynamic driver is proprietary tuned diaphragm wise and by further utilizing a physical low pass filter, it is to only function in minimal overlapping frequency range as opposed to the balanced armature driver. Coupled with delicate positional arrangement and front acoustic chamber design, AAW is able to achieve improved coherence, minimized phase shift and optimized arrival timing of music signal.

W900 is designed to be true reference equipment, it offers powerful yet natural sub bass which you will never find in a full balanced armature CIEM. The 4 way crossover network configures dedicated woofer, mid, treble and super tweeters. Inherited AAW's highly praised musical imaging, instrument separation and realistic sound stage, W900 steps up the game by offering extended treble and superior detail retrieval. The end result being a high-end speaker like performance condensed in a tiny footprint of CIEM.

AAW worked with the best balanced armature maker in the world to develop the bespoke super tweeter drivers used in W900. It ensures non-compromising sound pressure all the way up to 20kHz and further extends to 40kHz. 

Suitable for stage performers, recording studio, audio engineers and the most critical audiophiles. Every AAW custom is customised to fill exact cavity of your ears. The CIEM experience is started with a trip to audiologist to have ear impressions taken and AAW will carefully craft the monitor shells mirroring their shapes. Delicately tuned and matched transducers are then mounted into the shells to create a one of a kind earpiece for you and you only. Universal shape for W900 is also available.

 Meet Capri

Piling on the success of the Accessport, Capri is AAW's latest offering for iPhone music application. Designed to achieve Hi-Res music on-the-go and stay uncompromised on sound quality and mobility. We prefer to avoid the bulk of carrying amp stack or navigating through some awkwardly designed UI and laggy OS on digital audio players.

Without internal battery, storage, screen, complex operating system software, Capri uses your iPhone for these non-audio related functions and really focus on the sound design while lowering the overall cost. Therefore we can deliver sound quality which usually costs a few hundred dollars at a fraction of the price tag. Here comes Capri, barely bigger than the footprint of a traditional analog IEM cable, it brings an entirely new breed of portable audio experience on the table!

Capri can be ordered as complete earphone package with Capri In-Ear Monitor or standalone cable with MMCX/2Pin male connectors.

Both the analog and digital cables on Capri are constructed with 99.9997% purity OCC copper wires, supplied by our long time partner, cable specialist Null Audio. It is of excellent conductivity property and offer very low impedance to ensure obstruction free transportation of both the analog and digital signals. The digital cable connecting the Lightning connector and the control capsule is additionally shielded for maximum protection and to repel EMI interference. Leading into the IEM connector, Capri offers formable memory wire with over-the-ear configuration to keep a secure fit.

 Remote Control & Phone Call

Capri’s control capsule is equipped with a tri-button array, it mirrors the operation of a typical inline remote control with support of volume adjustment, next/previous tracks, answer/end phone call, call up Siri. Capri has high sensitivity microphone and 24bit/48kHz ADC circuitry built-in the control capsule and supports normal/conference phone calls, Siri or any iOS apps which utilise microphone functions.
