FIELD: physics, acoustics.
SUBSTANCE: invention relates to means of synchronising wireless headphones. In one embodiment, one speaker operates as the main speaker and other speaker operates as a secondary speaker. The main speaker receives digital audio data from a source and, in addition to reproducing digital audio received from the source, relays the digital audio to the secondary speaker. The main speaker additionally sends synchronisation data to the secondary speaker, such as data indicating the buffer status or the reproduction position of the main speaker. The secondary speaker uses the synchronisation data from the main speaker to control, for example, the status of its buffer or reproduction position so that the two speakers reproduce audio synchronously (for example, within 30 ms). In one embodiment, the main speaker uses a connection-based protocol, such as TCP/IP, in order to transmit buffered audio data to the secondary speaker, and uses a connectionless protocol, such as UDP or ICMP, for synchronisation data. Furthermore, the speakers can change the main and secondary speaker roles.
EFFECT: reducing Haas effect.
