The box is a charging device, and the headset can be used without the box, as long as there is a Bluetooth headset and a mobile phone.
First of all, turn on the switch of the Bluetooth headset, and then turn on the Bluetooth of the mobile phone, and then find the Bluetooth name of the Bluetooth headset on the mobile phone Bluetooth page (the name is generally on the instruction manual), and then press Connect, the headset will automatically connect to the mobile phone. If you don't know the name of the Bluetooth headset, try it one by one in the list of Bluetooth on your phone, and it will have a prompt \"Bluetooth connected!\"
