Abstract

An audio accessory for a headset. The accessory includes a first circuit for wirelessly receiving audio signals from a first external source of audio signals, a second circuit for mechanically coupling to a second external source of audio signals for receiving the audio signals from the second external source of audio signals, controlling circuitry for controlling the relative amplitude of audio signals from the first external source and the second external source transmitted to a playback device, a connector for detachably coupling to the playback device to transmit audio signals from the controlling circuitry to the playback device, and circuitry communicatingly coupling the controlling circuitry and the connector for transmitting audio signals from the controlling circuitry to the connector.
