The HD Series Design Concept
Fascinating High Resolution
The design concept is Fascinating High Resolution. The MLF diaphragm uses a remarkable material. When it‘s placed on a white plate, there’s no change, but when it‘s placed on a black plate, it has an iridescent effect. In order to take advantage of the beauty of the MLF material, we made it visible through the headphone housing, and made other audio parts black.
A Simple Design to Accentuate the
Iridescent Diaphragm
To express the high resolution in the headphones and head band, we examined many prototypes, but we ended up with a simple diaphragm-based design, and a unified black theme that emphasises the diaphragm.

Pursuit of the Ultimate Fit
Horizontal Slide Adjustment
We wanted users to barely feel the headphones. Based on ergonomics, we optimised the angle, shape, size and head dimensions for the head band, housing, and driver. Maintaining air tightness, the head band can be adjusted back and forth for a comfortable fit and an excellent, high-res sound.
3D Ergonomics Ear Pad (HD10)
We increased the air tightness of the ear pads by matching the shape to the indented part behind the ears and the part where the head begins to narrow at the top of the ears. Only a few companies can achieve this design.
HD10 and HD5 Design Differences
The HD5 concept is just like the HD10: Fascinating High Resolution and Pursuit of the Ultimate Fit. Similar materials are used, and the same HS Adjustment function is provided. However, the HD5 are designed for outdoor use, so they have a closer fit, and are lighter and more compact.
A Comment to the Readers
