7. Troubleshooting

• Headphones will not power on: Ensure the battery is charged. Connect the charging cable and allow it to charge for at least 10 minutes before attempting to power on again.
• Cannot pair with device: Make sure Bluetooth is enabled on your device and the headphones are in pairing mode (flashing indicator light). Move the headphones closer to your device and away from other wireless interference.
• No sound or low volume: Check the volume levels on both the headphones and your connected device. Ensure the headphones are properly connected via Bluetooth or AUX cable.
