1) Check that Master Buds Open is selected as the audio output on the mobile/laptop.

2) Android: in Bluetooth settings, tap the gear icon next to Master Buds Open and make sure “Media audio” and “Phone calls” are turned on.

3) Check that the media volume on the mobile is not at zero, and increase the earbuds’ volume (single tap on the right earbud).

4) If dual pairing is in use, pause the media on the other connected device – only one device plays audio at a time.

5) Disconnect and reconnect the earbuds or restart the mobile.

6) If the issue continues, RESET the earbuds and pair again.
