The function of the wireless Bluetooth headset base is the same as that of the current solid-state wireless Bluetooth headset bin. Its base is connected to the power supply, which can charge the earphone. Because the battery of the earphone is relatively small, the stored electricity is not too much. When not in use, Urban usually puts it in the socket to charge. Because he has no wires, he can only charge his headphones by a base with two metal points. Now it is designed as an earphone compartment.
