Troubleshooting
- Headphones won't power on: Ensure the headphones are fully charged. Connect them to the Type-C charging cable and a power source for at least 1.5 hours.
- No sound: Check the volume level on both the headphones and the connected device. If using Bluetooth, ensure the headphones are properly paired and connected. If wired, ensure the 3.5mm audio cable is securely plugged into both devices.
