Newly designed driver

f-Core DU driver unit  

Speed is one of the most important components of diaphragm design. final increased the speed of the custom-built f-Core DU driver unit by using an ultra-thin CCAW voice coil. In addition, they used brass for the driver housing, which is resistant to magnetism and contributes to an overall better driver.

Ear hooks that eliminate cable touch noise

The A4000 uses an ergonomically designed ear hook that accommodates a vast range of ear shapes and sizes. The design also alleviates cable touch noise, the rustling sound that occurs when the cable rubs against your body.

Silicon carrying case
