Troubleshooting

1. Unable to turn on headphone: Ensure the battery is fully charged and the power button is pressed correctly.
2. Unable to connect headphone: Verify the indicator LED is blinking RED and BLUE alternately. If it blinks BLUE slowly, the headphone is already connected to another device; disconnect that device and try again.
3. Unable to reconnect headphone: Confirm that Bluetooth is enabled on your device.
4. Less transmission distance: Ensure your device's Bluetooth version is 4.0 or above, as older versions may result in a shorter transmission range.
