Notes:
Turn on the video mode can drop latency to about 150ms and improve video watching
experience, but it will shorten the connection distance. We suggest you turn off the
video mode when you use the speaker for playing music.
Video mode does not support the True Wireless Stereo connection mode.
The normal mode provides latency about 250ms.
Bluetooth technology can not fully eliminate the latency of Bluetooth audio.
