Troubleshooting Guide
| Problem | Solution |
|---|---|
| Headphones do not power on. | Ensure the headphones are fully charged. Press and hold the Power/Multi-function button for a sufficient duration. |
| Cannot pair via Bluetooth. | Ensure headphones are in pairing mode (LED flashing red/blue). Turn off and on Bluetooth on your device. Move headphones closer to your device. Clear previous Bluetooth connections on your device. |
| 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 securely connected. Try playing different audio sources. |
| ANC is not working. | Ensure the ANC switch is in the 'ON' position and the ANC LED is illuminated. ANC is most effective against low-frequency, constant noise. |
