Abstract:
An audio data transmission method and device for a wireless headphone, and a storage medium and a terminal. Playback modes used by the wireless headphone comprise a first playback mode and a second playback mode. The method comprises: determining, at least according to parameter information of audio data to be played, whether the first playback mode currently used by the wireless headphone satisfies a transmission bandwidth required by said audio data; and when a determination result indicates that the first playback mode does not satisfy the transmission bandwidth required by said audio data, transmitting said audio data by means of a connection channel corresponding to the second playback mode. According to the solution provided by the present invention, different playback modes can be switched according to the quality requirements of music to be played, both tone quality and power consumption are taken into account by combining the characteristics of the different playback modes, and therefore, the implementation of a wireless true high-definition lossless headphone solution becomes possible.
