Claim 5:
6. TWS earphones, comprising a main earphone and a secondary earphone,
wherein the main earphone and the secondary earphone use one or more residual slots for data interaction as follows:
1) When the main earphone and the secondary earphone receive a data packet sent by an audio source, the main earphone and the secondary earphone use a first residual slot of a data transmission slot, wherein the first residual slot is remaining of the data transmission slot after the data packet is transmitted;
2) When a data packet is received and the main earphone sends acknowledgment information to the audio source, the main earphone and the secondary earphone use a second residual slot of a first next data transmission slot, wherein the second residual slot is a remaining of the first next data transmission slot after the acknowledgment information is sent;
3) When a data packet is received and the main earphone sends acknowledgment information and extra information to the audio source, the main earphone and the secondary earphone use a third residual slot of a second next data transmission slot, wherein the third residual slot is a remaining of the second next data transmission slot after the acknowledgment information and the extra information is sent; and
4) When the main earphone does not receive audio data sent by the audio source correctly, the main earphone and the secondary earphone use a fourth residual slot which is a remaining of a third data transmission slot;
wherein based on durations of the residual slots, and timing and period of the interactive data transmitted between the main earphone and the secondary earphone, the interactive data is determined to be of a certain type.
