2. Bluetooth audio device's output is not set as the headphones?
1) Using with Window PC please refer --

3. Headphone volume is too low.
There is a minor chance that your headphone volume is really low and that's why you cannot hear anything. Pls try to tap click the + button to increase the volume.
4. Headphone is defective
Normally, when you plug a USB power cord into the headphone, you can see the LED light turns red. If no LED lights at all when you try to charge, and when you press and hold the MFB for 5s and no LED light at all, then the headphone might be defective.
We also suggest you to try with another USB cable because there is a higher chance the USB cord is broken than the headphone itself.
