Functions
Playing music
Hands-free conversation
Note:
- Turning on the game mode can drop latency to as low as 100ms and improve the gaming and watching video experience, but it will shorten the connection distance. We suggest you turn off the game mode when you use the earbuds for music.
- The normal mode provides a latency of about 200.
- Bluetooth technology can’t eliminate latency.
