Abstract: A headset for voice communication is provided comprising an earphone unit having a speaker, a microphone boom comprising one or more microphones wherein the microphone boom is rotatably interconnected with the earphone unit to allow for 360 degrees rotation. The microphone signals are transmitted from the microphone boom to the earphone unit via an optical transceiving unit having a transmitter and a receiver, wherein the microphone boom comprises the transmitter and the earphone unit comprises the receiver.

Abstract: An apparatus (301) for communication according to a Universal Serial Bus, USB, specification, comprising: a first USB device (301) and a second USB device (306) for connecting operatively to a first USB host and a second USB host, respectively; an audio interface stage (320) configured to interface with an audio component such as a headset; and audio controller (316). The audio controller (316) is configured with: a first channel (327), channeling audio signals between the first USB device and the audio interface stage (320), and a second channel (328), channeling audio signals between the second USB device and the audio interface stage (320); wherein the audio controller (316) automatically switches between the first channel (327) and the second channel (328) while giving priority to audio signals on the first channel over audio signals on the second channel.
