The disclosure provides a synchronization method, a synchronization device, and a transceiver device for multi-channel data transmission. The synchronization method transmits test data to N receiving devices, obtains a transmission cycle and N delayed playback timestamps based on the information fed back by the receiving devices, the data packet preparation time, a first time, and a predetermined error tolerance time; transmits audio data packets to the N receiving devices, obtains an existing data playback duration and a time difference based on the acknowledgment packets fed back by the receiving devices; adjusts the predetermined error tolerance time to a target error tolerance time according to the comparison result between the time difference and a predetermined time difference threshold. This achieves real-time and timely adjustment of the delayed playback time of audio data packets according to the actual situation of data transmission, thereby achieving the purpose of audio synchronization in multi-channel wireless transmission.
