When the earphone and the base station are in a communication range, the base station broadcasts control information and state information through a third channel, namely a full slot, and sends first audio information through a first channel. When the earphone to be communicated is a specific earphone, the information is sent to the corresponding earphone through a first channel, namely 3 long-time-slot sending channels; when the earphone needing to be communicated is an idle earphone, according to the response state of each idle earphone, the idle earphone is sent to the corresponding earphone or earphones through the first channel, namely 3 long-time transmission channels.
Specifically, the base station uses 3 Long slots as a transmission channel and 1 Full Slot as a reception channel. Each earphone uses 7 Full slots in total, wherein 6 Full slots are occupied for transmitting high sound quality, and 1 Full slot is used as a broadcast channel instant channel shared by all earphones. Each base station supports at most 3 earphone connections, 22 full slots are used, and the rest 2 full slots can be reserved for expansion, such as replacement when the channel is occupied or damaged.

Specifically, whether communication registration is needed or not is determined in time by judging whether the headset needing communication is in communication connection with the base station for the first time. And when the earphone needing communication is not in communication connection with the base station before, finishing communication registration on the base station according to the base station information of the base station and the earphone information of the earphone, and establishing communication connection with the base station through an air protocol.
