Subtle and realistic
Air Motion Transformer

With the accordion-shaped diaphragm, each of its pressing produces a powerful, surging high note that is not only quick and accurate in its performance, but contains in its rendering of voice a rich texture of grain and a scent of rosin.

Gentle and smooth
Planar Magnetic Driver

The extremely thin, soft and film-like diaphragm in the driver produces a light, broad and clear tone with its vacillating movements, thereby retaining the reality of every musical detail and conveying a live-experience sound quality.
