Hybrid IEM With TrueXross Technology

Advanced AcousticWerkes is well loved among the Massdrop community for its CIEM offerings, which include the A3H Pro. Now, the company continues its streak of top-notch hybrid in-ear monitors with the AXH: a universal-fit IEM that combines a 10-millimeter proprietary dynamic driver with four balanced-armature drivers. By using TrueXross technology, this model addresses the crossover problems of many multiple-driver IEMs, which lead to chaotic phase shift and scrambled arrival timing. The dynamic driver has an individually tuned diaphragm, and by utilizing a physical low-pass filter, it functions in a minimal overlapping frequency range as opposed to the balanced-armature driver. Pairing delicate positional arrangement and a new copper acoustic bore design, AAW achieves improved coherence, minimized phase shift, and optimized arrival timing of the music signal. 

Note: At checkout, choose the blue swirl or gold swirl shells. Both styles have blue buckeye faceplates. 

The Reviews Are In

One reviewer says, “Overall, it's a very coherent sound that excels in technicalities, especially in its price range. I think AAW has managed to improve vastly upon the original tuning and created an earphone that is able to hold its weight and some, and at its price versus specs, I feel it's really good value and would be a good neutral IEM that isn't sterile.”
