A system and method is provided for monitoring a plurality of audio sources and switching from one to another of the audio sources in accordance with a stored program. An audio output device receives a signal from each of the portable electronic devices and selectively switches the contents of its output according to at least one preprogrammed user preference. The audio output device also automatically communicates with transceiver modules connected to local information systems, for example within a vehicle, office or shopping center. Based on programs stored in a storage device connected to the headset, the local information sources may be monitored and selected to interrupt other audio sources received by the headset when desired.
