With AFDS (Air Film Damping System), the planar magnetic model was reinvented. Leaving the merits of the planar magnetic model – a lightweight vibration system and superior reproduction of high frequencies – as is, the employment of AFDS expands the reproduction frequency band with a bass bias, and makes the use of breatheable earpads possible. Compared to the conventional planar magnetic model, with which tightly sealed earpads had to be used to suplement bass frequencies, the natural, open sound achieved is of a quality worthy of being termed a reinvention.
