The first packet records a first packet transception time difference. A second packet is received from the second wireless earphone. The second packet records a second packet transception time difference. A synchronization state between a first wireless earphone and the second wireless earphone is obtained according to the first packet transception time difference and the second packet transception time difference. A play progress of playing a specific audio by the first wireless earphone or by the second wireless earphone is adaptively corrected according to the synchronization state between the first wireless earphone and the second wireless earphone.
