This is a two-plug version of our popular boom-mike set. Recommended when you know that the single-plug model (MS50/T30-1) will not work for you. This can be the case in light planes and some very old air carrier aircraft. Many pilots use this set at work on the jets, then take it home to use in a light plane. Plantronics Part Number: 90101-01
