The Ultra Single Headset with Shell-Mount PTT & Motorola 2-Pin Connector from Eartec features a full earcup and comes with a unique heptagonal design that covers the ear naturally and completely. The deluxe ear cushions are not only wide and soft but slightly thicker near the bottom and rear. This headset includes a 2-pin connector (3.5mm, 2.5mm) that is compatible for use with Motorola radios. The headset allows users to wear their radios clipped to the belt and communicate through their headset. The industrial grade shell-mount Push-to-Talk (PTT) acts as the intermediary between the headset and the transceiver. The headset is widely used in football matches by coaches for communication and also in theatre and arts.
