Abstract: A multi-purpose telephone accessory unit for persons who use a telephone for extended periods of time. It is connected to a conventional telephone by removing the telephone cord from the normal handset and plugging it into the accessory unit. The unit wears a headset equipped with two independently controlled ear piece receivers and a mouth piece transmitter. An external wall plug type A.C./D.C. transformer is used to provide power for the unit. The unit has separate volume controls and separate equalizers for the respective ear piece receivers. A mute switch is connected into the voice transmission circuit to allow the user to speak with other persons in their area without the person on the other end of the telephone line hearing the conversation. An internal microphone is also provided that can be connected through the mute switch that allows the user to pick up voices and sounds in their immediate vicinity of the unit without the user having to remove the ear receiver unit.
