HP Poly MS50 Commercial Aviation Headset (two-plug version 
This super lightweight, single-sided aviation headset features a solid-state amplifier with a mini-microphone, five foot cable, and two plugs - (PJ068 and PJ055). Wear it with the included headband or mount the MS50 on an after-market custom molded ear piece, that eliminates the need to wear the headband. This is the two-plug version of Plantronics popular MS50 Series boom-mike aviation headset. Recommended when you know that the single-plug model (MS50-T30-1) will not work in your aircraft.
