After receiving the package, you will not be able to use the headset. It may be powered off. The first thing to do is to charge the headset box for 60 minutes. Very important. Thanks! If only one side of the headset is working, please disconnect the Bluetooth link, delete the Bluetooth link record of the mobile phone, and re-link it again.
