To protect users from potential hearing damage, Android's limit
on max volume is quite low for Bluetooth audio devices.
If you feel the volume is too low, please access developer options
and enable absolute volume, so you'll be able to max
the volume at your own volition and to the full
capabilities of your Bluetooth earphones.
