Claim 11:
12. An earphone synchronization method adapted for a true wireless earphone system comprising a first wireless earphone, the method comprising:
transmitting a first packet to a second wireless earphone by the first wireless earphone during an ith period, wherein the first packet records a first packet transception time difference measured by the first wireless earphone during an i−1th period, where i is an index value;
receiving a second packet from the second wireless earphone by the first wireless earphone during the ith period, wherein the second packet records a second packet transception time difference measured by the second wireless earphone during the i−1th period;
obtaining a synchronization state between the first wireless earphone and the second wireless earphone by the first wireless earphone according to the first packet transception time difference and the second packet transception time difference; and
adaptively correcting, by the first wireless earphone, a play progress of playing a specific audio by the first wireless earphone or by the second wireless earphone according to the synchronization state between the first wireless earphone and the second wireless earphone.
