These headphones are designed to faithfully reproduce sound from an audio source. The signals are processed digitally and transformed without compression to conventional amplifiers. The specialised wires required for this are embedded inside a rigid metal arm, which is both functional and visually appealing. Through its curvature, the earpads fit firmly to the ears, which is important for both sound quality and wearing comfort. The flat diaphragm adapting to the slant of the ears also contributes to a good fit.
