Excels in terms of high frequency harmonic overtone reproduction.
The flagship model SONOROUS X employs a driver unit integrated with the front plate, which results in resonance being suppressed and clear sound quality. With the same titanium diaphragm employed with SONOROUS X, this model excels in the generation of high frequency harmonic overtones, achieving high resolution sound.

Ear pads with an internal sound absorption section that contribute to clear sound quality
The ear pads play an important part in sound quality. When there is a space between the ear pad and the ear, low frequency acoustic pressure changes greatly, and this greatly influences sound quality. So as to achieve a superior fit where it is hard to create a space, we've employed synthetic leather, which has an equal amount of flexibility both horizontally and vertically, and have chosen a sponge with just the right amount of flexibility. Establishing apertures on the inside and the outside of the ear pads makes for clear sound quality
with sealed headphones.
