Abstract

An apparatus and method for an audio channel switching headset are described. The method includes detection of a plurality of audio sources within communication range of a wireless headset device. Once the plurality of audio sources are detected, an audio link may be established with a pre-determined number of the selected audio sources. Finally, a user of the headset device is provided, via a plurality of headset audio channels, access to each audio source within an established audio link. Accordingly, a user of such a headset device may listen to audio sources simultaneously or may toggle between various audio sources using a mechanical switch or voice-activated toggling of audio sources. Furthermore, a user may request additional audio channels, which are enabled by a host device, which multiplexes multiple audio sources with a single device audio link.
