All Music Series headphones have a vented diaphragm design that incorporates a large air chamber. This design lowers the frequency resonance (distortion) of the diaphragm and extends bass response. A unique process to de-stress the diaphragm results in enhanced inner detail. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth while avoiding breakup at lower frequencies.

The Music Series One, Two and Pro headphones all feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen free copper. Ultra-high conductivity copper yields the clearest transmission and lowest coloration possible. This combined with high power neodymium magnets provide maximum efficiency giving a smoother, cleaner and more dynamic sound and a larger perceived sound stage.
