Troubleshooting
If you encounter any issues, please refer to the following common solutions:
| Problem | Possible Solution |
|---|---|
| Headphones do not power on | Ensure the headphones are charged. Connect to a power source using the USB Type-C cable. |
| Cannot pair via Bluetooth | Ensure headphones are in pairing mode (LED flashing red/blue). Turn off and on Bluetooth on your device. Move closer to the device (within 33 feet). Forget the device in your Bluetooth settings and try pairing again. |
| No sound or low volume | Check volume levels on both headphones and your connected device. Ensure headphones are properly paired or the 3.5mm cable is fully inserted. Try another audio source. |
