Troubleshooting

- Unable to pair via Bluetooth: Make sure the headset is in pairing mode (indicator light flashing). Turn off and on Bluetooth on your device, then try searching again. Ensure no other devices are currently connected to the headset.
- No sound: Check the volume level on both the headset and your connected device. Ensure the correct playback mode (Bluetooth, TF card, AUX) is selected or automatically activated.
- Poor sound quality: Move closer to your Bluetooth device to reduce interference. Check for obstructions between the headset and the device.
- Active Noise-Cancellation (ANC) effectiveness: While the W35 Air features ANC, its performance can vary depending on the type and intensity of ambient noise. For optimal results, ensure a snug fit of the earcups.
