MDR-V900HD - circumaural
- Circum-Aural Earcup Design in the natural shape of the human ear places the driver unit at a correct distance from the ear canal and creates a sealed resonance chamber over the earlobe itself, reducing pressure on the ear for a more comfortable fit.
- Aura-Nomic Designed Driver Unit is positioned within the earcup at an angle which directly corresponds to the angle of the opening of the ear canal for the most natural listening experience possible.
- Neodymium magnet is small, yet five times more powerful than a ferrite magnet of comparable size, to provide a better headphone without increasing the overall size and weight of the driver unit.
- Newly developed High Definition Driver Unit helps clearer and richer sound with wider frequency reproduction up to 80k Hz.
