Abstract
A wireless audio client device such as a headset worn by a user allows the user to talk with multiple other devices using different communication protocols. In one approach, the wireless audio client device is a slave device which pairs with multiple master devices such as a game console and cell phone. The wireless audio client device uses a common set of peripherals such as a speaker, microphone, RF antenna, battery, status lights and control buttons. Processing circuitry is provided in one or more chips, to handle the different communication protocols. The wireless audio client device can automatically interrupt a game chat to allow the user to accept an incoming phone call, or can prompt the user to accept the call. Or, the wireless audio client device can play audio from the cell phone while the game chat continues.
