Abstract: A communication protocol provides improved 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 between the two ear pieces (12a, 12b) of the wireless stereo headset (12). 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. Using special control messages on connection between the ear pieces (12a, 12b), the ear pieces (12a, 12b) inform each other which audio information has been received successfully from the host device (19).

Abstract: A dual-microphone arrangement (300) provides improve voice performance in a wireless headset (12). A vibration sensor (1130) is used for voice pickup and will add low-frequency voice audio content in windy conditions. An equalizer (810) is used to restore low-frequency voice audio content in wind-free conditions. Depending on the measured wind power, the output will derive more signal from the equalizer (810) or more signal from the vibration sensor (1130).
