The Ultra Double Headset with 2-Pin Shell Mount PTT Connector for Kenwood 2-Way Radios from Eartec features a full ear-cup and has 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 is compatible with Kenwood 2-way radios. The headset allows the user to wear his radio clipped to the belt and communicate through the headset. The industrial-grade shell mounted push-to-talk (PTT) is also worn on the belt or clipped to the user's clothing. This assembly acts as the intermediary between the headset and the transceiver.
