The Eartec Monarch Inline PTT Headset for SC-1000 Radio Transceiver allows you to wear the radio clipped to your belt and communicate through the headset. This headset features a slender black band that offers a unisex fit. This headset is equally at home on the floor of a TV studio or inside the cab of a tower crane. The headset includes an inline Push-to-Talk button that acts as an intermediary between the headset and the transceiver.
