Abstract

The invention provides an audio data transmission method between double wireless earphones, and the double wireless earphones. The method comprises the following steps: a first wireless earphone performs data link with a wireless communication module of an audio player through a first wireless communication module to receive audio data; when the first wireless communication module receives first frame of audio data, the first wireless communication module inserts a playing starting time in an audio data packet; the audio data packet carrying the playing starting time is decoded and is divided into two paths of sound channel data, wherein one path of sound channel data outputs audio, and the other path of sound channel data is encoded; a second wireless communication module of the second wireless earphone receives the encoded audio data packet; the second wireless communication module of the second wireless earphone controls a playing starting time point according to the playing starting time in the encoded audio data packet. According to the audio data transmission method, the sound of the two earphones in wireless communication link reduces the blockage and generates no drift with time by means of wireless communication protocol extension and delay control.
