With the planar magnetic drivers, the headphones offer a frequency response of 8 Hz to 65 kHz with an impedance of 35 Ohms. The comfortable headband is designed to accommodate a wide range of head sizes, while the asymmetrical ear cups follow the natural shape of the human ear for a proper seal that's comfortable for long listening sessions. The outer enclosure is CNC milled and hand-polished for a striking appearance. The headphones ship with a standard 3.5mm cable and an updated 4.4mm balanced cable, as well as a 3.5mm to 1/4" adapter.
