Check whether your Bluetooth headset supports music playback. Generally, monaural
Bluetooth headsets in the market don't support music playback over Bluetooth.
Go to Settings > Bluetooth, in the available devices list, check whether the Bluetooth
headset has been connected to your phone. If no, reconnect your phone to the Bluetooth
headset.
Check the model of the Bluetooth headset.
Check whether the Bluetooth device can be properly connected to other phones for
phone calls. If yes, contact the relevant technical engineer to solve the problem.
Make phone calls when signals are stable and make sure there is no building between
your phone and the Bluetooth headset.
