  • Publication number: 20140148101
    Abstract: A wireless microphone and wireless earpiece each may exchange radio frequency (RF) signals with a base unit and render content contained within the exchanged RF signals to a user. This wireless earpiece further includes a wireless interface, a processor, a speaker, a user interface, and an authentication module. The wireless interface allows the earpiece to wirelessly communicate with the base unit. The processor recovers communications exchanged with the base unit that the speaker then renders audible. A user interface coupled to the processor may alert the user to any additional incoming audio communications. Having received the alert, the user may select between the communications. The authentication module allows the wireless earpiece and microphone to pair and register with the base unit.
