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).
