D8000 are planar magnetic headphones that incorporate newly-developed AFDS (Air Film Damping System) technology.
Development began on this project in 2014 under the concept “A product with the kind of overwhelming sound quality understood by everyone”. AFDS was developed on the back of a variety of physical analyses. AFDS is a braking mechanism whereby the diaphragm is sandwiched between perforated metal with extremely precise openings and the friction of the thin layer of air (air film) between the diaphragm and the perforated metal is controlled. Conventional planar magnetic models excel in terms of medium and high frequency sensitivity, but with low frequencies where amplitude increases, the diaphragm comes into contact with the magnets; as a result, there is an insufficiency in terms of bass tone reproduction. With AFDS, this problem is solved, with no impact on high frequency characteristics. We’ve achieved sound quality unheard of until now, quality that has both the sensitive high ranges of planar magnetic models and the volume and open feel bass tones of dynamic models.
With these, you can enjoy a new sound that is a step ahead of other planar magnetic models.
