The Ultra Single Headset with Shell-Mounted PTT from Eartec features a full ear-cup 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 ergonomically designed headset can be used with existing wired intercoms as well as all Eartec transceivers and wired systems. It is compatible with Kenwood, Motorola and 2-way radios from most manufacturers. The headset allows users to wear their radios clipped to the belt and communicate through their headset. The industrial grade shell-mounted 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.
