AAW AXH 5-Driver Custom In-Ear Monitor is a custom-fit in-ear monitor from AAW (Advanced AcousticWerkes), shaped from your ear impressions or a 3D scan of your ears. We take impressions at our studio in Singapore, and every custom IEM comes with a Null Audio cable.
AAW is known for our exquisite hybrid drive technology, AXH is our latest effort in suchĀ ideology of combining the best traitsĀ out of dynamic and balanced armature drivers.Ā 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 TrueXrossTMĀ to solve the classic coherence issue in hybrid earphones.
The dynamic driver is individually tuned diaphragm wise and by further utilizingĀ 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 the new stainless steel acoustic boreĀ design, AAW is able to achieve improved coherence, minimized phase shift and optimized arrival timing of music signal.
AXH is tuned with a balanced soundĀ signature in mind, it offers controlled yet natural sub bass which you will never find in a full balanced armature setup. The dedicatedĀ super high balanced armature drivers offer crystal clear details in the vocal and treble range. TheĀ treble extension is well controlled to provide a non-fatiguing listening experience. The binaural sound-stage is reproduced as realistic as a pair of full sized headphone.
Suitable for band performances, emerging artists, worship events and anybody who appreciates fine listening experience.Ā
