I have a headset with it's own volume control, and I can also control the volume of the music through the android's volume control keys.
But which way of controlling is more battery efficient?
- Have my android device on full volume and control it with my headset's control.
- Have my headset on full volume and control it with my android device.
- None of the answers above. (if so, then which?)
EDIT: I'm not talking about an electronic controlled headset, I'm talking about a headset controlled by a dial resistance.
