Technology and Features

2 patents are still in process, so we cannot explain with too many details.

​

Natural bass performance.  ( Although the natural bass signal frequency is lower than the resonant frequency of the bass driver )

​

We can build TWS and Bluetooth earphone in the future. 

​

360-degree earphone converts the digital signal into the analogue signal.

​

Enhancement of bass performance would not hurt your ears because the bass sound does not go through human eardrum.
