Abstract: A communication protocol provides improved bidirectional communication performance between a wireless stereo headset (12) and a host device (19). The communication protocol provides communication paths between the host device (19) and each ear piece (12a, 12b) of the wireless stereo headset (12), as well as a communication path (17) between the two ear pieces (12a, 12b). In addition to receiving audio information from the host device (19), each ear piece (12a, 12b) may request audio information from the other ear piece (12b, 12a), thus obtaining path diversity in the downlink. One ear piece (12a, 12b) may acknowledge the host device (10) for a correctly received packet, which the other ear piece (12a, 12b) missed, avoiding retransmissions. The ear pieces (12a, 12b) may exchange picked-up voice content to send to the host device (19), providing for path diversity in the uplink.
