Selecting the sound quality mode of
music playback
The sound quality is set to the “Standard” mode (SBC high quality
mode) as the default setting.
When using an AAC or aptX compatible device, select the “Priority
on sound quality” mode.
If the connection is unstable, such as when producing only
intermittent sound, select the “Priority on stable connection” mode.
Sound quality and the indicator (blue) of each mode
When the sound quality mode is switched, the headset indicates the
remaining battery capacity by flashing the indicator in red first, and
then in blue to indicate the sound quality mode. You can check the
current sound quality mode by the number of flashes of the indicator
(blue).
