Abstract: A hands-free system for communicating over a cellular phone connection without handling the cellular phone is provided including a powered hands-free kit to which a cellular phone is connected. The hands-free kit has an electrical circuit and connector for exchanging audio information with the cellular phone. The hands-free kit also includes a condenser microphone for receiving audio data from the user and transmitting it through the user's cellular phone handset to a person with whom he is communicating by cellular connection. The hands-free kit may transmit through a cassette device or a FM transmitter audio information to a car stereo system such that audio information may be reproduced through the speakers of the car stereo system for excellent sound quality and versatility. Thus, one or more users may participate in a conference call utilizing the condenser microphone and stereo speakers of the car within which they are riding.
