Due to some phone's operating systems, you may find your volume is too low.
To resolve this, enable Media Volume Sync settings in your phone's Bluetooth settings, to ensure that the phone system volume will sync with the headphones volume.
For Samsung devices running Android 8 and above:
- Open Settings.
- Tap Connections.
- Tap Bluetooth.
- Tap the three-dot menu icon in the top right corner of the screen.
- Tap Media Volume Sync.
- Tap the toggle switch in the top right corner of the screen to turn Media Volume Sync on.
For Huawei devices:
- Enable developer mode by going into Settings and tapping on ‘Build Information' 7 times. This will enable a developer settings menu where you will see Developer Options.
- Tap the toggle switch for Bluetooth Absolute Volume, turning the toggle on.
Please note: Do not do this while wearing the headphones, as this may cause a sudden large increase in volume.
