Patent abstract
A headset containing 2 earphones is described. The headset includes an anti-noise circuit, a radio system circuit, and a sound collection circuit for providing an anti-noise capability. One of the earphones defines a cavity having an external input terminal therein. An output terminal of a conventional MP3 player is coupled to the external input terminal when the player is disposed in the cavity. The output terminal is coupled to the radio system circuit so that music played by the MP3 player can be transmitted to the earphones. A keeper is provided to retain the MP3 player in the cavity.
