Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Headset won't turn on | Low battery | Charge the headset for at least 2 hours. |
| Cannot pair with device | Headset not in pairing mode; Bluetooth off on device; device too far | Ensure headset is in pairing mode (flashing red/blue). Turn on Bluetooth on your device. Keep devices within 1 meter during pairing. |
| No sound or low volume | Volume too low; headset not connected; media audio not selected | Increase volume on both headset and connected device. Reconnect the headset. Check device's Bluetooth settings to ensure media audio is enabled for the headset. |
