How to Sync Volume on Android
- 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.
