Focused on the Minute Details of Sound

With the JVC HA-FD01, we focused on the minute details of sound. Our goal was to eliminate the fuzzy part of the sound and express its outline by reproducing the details to let the sound stand out.

Introducing the D3 Driver Unit

The most prominent part about this product was the development of a new driver unit called the D3 driver. D3 stands for "dignified, distinct, and delightful," and these words describe the conceptual direction of this driver unit.

DLC Dome Dual Carbon Diaphragm

To realize the three D's, the driver unit is embedded with a specially developed diaphragm called DLC Dome Dual Carbon. This diaphragm is composed by layering four different materials – two high molecular polymers and two amorphous carbons. At the center of the diaphragm is a dome area using polyethylene naphthalate (PEN), which is a material offering higher strength than PET. This dome area is coated with a diamond-like carbon (DLC) film for stability and strength.
