music with a headset?
1.
Press the volume up button to increase the volume.
2.
Check whether the earpieces of your headset are blocked by foreign bodies. Clean them
periodically.

Play a loud ringtone to check whether the low volume problem is caused by bad audio
sources. If so, replace the music file and try again.

your phone's voltage output limit.
