Troubleshooting
Common Issues
| Issue | Solution |
|---|---|
| No sound from headphones. | Ensure the USB-C connector is fully inserted into your device. Check your device's volume settings and the headphone remote's volume. Confirm the correct audio output device is selected on your computer or mobile device. |
| Poor sound quality or distortion. | Verify the audio source is of good quality. Adjust the EQ presets on the remote. Ensure the earcups are properly positioned on your ears. Try connecting to a different device to rule out source issues. |
