The devices will be synchronized immediately without codes. You will hear a confirmation sound and the INDICATOR (5) will flash blue.

Auto power off

Your Headphones 7 Bluetooth ANC will automatically turn off in the following situations:

  • After 5 minutes in search mode, if they are not synchronized with another device.
  • After 30 minutes, if they are synchronized and music is paused.

Bluetooth playback control

Once your Headphones 7 Bluetooth ANC are syncronized, you will be able to control basic playback functions such as turning up and down the volume and switching to the next or previous song directly from your headphones.

Press the VOLUME + (1) and VOLUME - (3) buttons to turn up and down the volume respectively. You will hear a beep when reaching the maximum volume level.
