Advanced AcousticWerkes W300AR Hybrid Custom In-Ear Monitor

AAW is known for our exquisite hybrid drive technology, W300AR is another classic representation of suchideology of combining 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 TM to solve the classic coherence issue in hybrid earphones. The dynamic driver is individually 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 bore design, AAW is able to achieve improved coherence, minimized phase shift and optimized arrival timing of music signal. W300AR is designed to be a true reference equipment, it offers controlled yet natural sub bass which you will never find in a full balanced armature setup. The dedicated mid/treble balanced armature drivers with individual sound bore offer crystal clear details in the vocal range, extremely smooth yet extended treble. The high resolution music reproduction enables you to hear every nuance in your music. The 3D binaural sound-stage is imaged as realistic as a pair of high end headphone.

Suitable for vocalists, 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 an one of a kind earpiece for you and you only.
