1. An audio data transmission method for a wireless earphone, wherein a play mode adopted by the wireless earphone comprises a first play mode and a second play mode, and the method comprises:
determining whether the first play mode currently adopted by the wireless earphone satisfies a transmission bandwidth required by to-be-played audio data at least based on parameter information of the to-be-played audio data; and
based on the first play mode not satisfying the transmission bandwidth required by the to-be-played audio data, transmitting the to-be-played audio data through a connection channel corresponding to the second play mode;
wherein said transmitting the to-be-played audio data through the connection channel corresponding to the second play mode comprises:
determining a play mode switching duration;
transmitting pre-cached audio data through a connection channel corresponding to the first play mode, so that the wireless earphone performs audio data precaching before switching, wherein a duration of the pre-cached audio data is determined based on the play mode switching duration; and
transmitting the to-be-played audio data through the connection channel corresponding to the second play mode from a termination position of the pre-cached audio data.
