In this embodiment, no matter what kind of device the bluetooth headset is paired with and wirelessly connected, for example, what the bluetooth headset is paired is the terminal that charges for the bluetooth headset, the bluetooth headset still sends bluetooth information to the terminal through the wired Type C connector. The bluetooth information is used for the terminal to determine whether the currently paired bluetooth headset of the terminal is the currently charging bluetooth headset, and the bluetooth information includes, but is not limited to, a bluetooth Name, a bluetooth Mac address, bluetooth status information, and the like.
