The 63 mm planar drivers use neodymium magnets and ultra-thin diaphragms for deep sound extending below 20 Hz. Alongside clear sub-bass, the headphones offer a layered soundstage with smooth, clean treble, detailed midrange and vocals placed deeper in the scene.

The strong next-generation frame is CNC-machined, with aircraft-grade aluminium, a polymer-ceramic coating and Corning Gorilla Glass inlays. Sheepskin earpads and a high-quality flexible leather headband provide comfort. Magnetic size adjustment and a low-clamp Ultrasuede suspension follow different head shapes gently.
