Troubleshooting
If you encounter issues with your headphones, refer to the following common solutions:
| Problem | Solution |
|---|---|
| Headphones do not power on. | Ensure the headphones are fully charged. Connect to a power source using the USB-C cable. |
| Cannot pair via Bluetooth. | Make sure the headphones are in pairing mode (flashing LED). Turn off and on Bluetooth on your device. Ensure no other devices are currently connected to the headphones. Try 'forgetting' the device on your phone and re-pairing. |
| No sound or choppy audio. | Check volume levels on both headphones and your device. Ensure Bluetooth connection is stable or try a wired AUX connection. If using an SD card, ensure it is properly inserted and the files are compatible. |
| Headphones are uncomfortable or too tight. | Adjust the headband for a better fit. The over-ear cushions are designed for comfort, but individual fit may vary. |
| Cannot connect to multiple devices simultaneously. | These headphones typically support connection to one device at a time. Disconnect from the current device before attempting to connect to another. |
