i12 TWS Troubleshooting

Please make sure both ends of the USB cable are securely connected. If you use a power outlet, ensure that the power supply is connected securely and the outlet works. If you use a computer, make sure it is connected and the USB port is powered. Try to turn on the headset and then turn them off. Disconnect and reconnect the USB charging cable.
1. Please check whether your headphone is in pairing mode or reconnect mode and check whether your mobile phone Bluetooth search function is opened;
2. Check your mobile device's Bluetooth menu and delete / forget the headphones, then reconnect the headphones following the instructions in the user manual.
Please check if there is metal or any other material within a relatively close range that may interfere with the Bluetooth connection. Bluetooth is a radio technology that is sensitive to objects positioned between the headphone and the connected device.
Check if the head phones are turned off and the headphone is paired. If necessary, pair the headphones with the audio source again. Check the connection of your audio source. If the volume is too low, turn up the volume.
App Software settings may vary according to some functions of the App itself not depending on the phone.
