The Ultra Single Inline PTT Headset for SC-1000 Radio Transceiver is a versatile headset accessory for two-way radio use. It features Push-to-Talk activation. This headset allows users to wear their radios clipped to their belts and communicate through it. The comfortable full-ear-cup features a unique heptagonal design that covers the ears naturally and completely. Deluxe ear cushions are not only wide and soft but are also slightly thicker at the bottom and rear. Together, these ergo-formed shapers are the reasons that make this headset comfortable to wear. It also includes an inline Push-to-Talk button that is worn on the belt or clipped to the user's clothing. This assembly acts as an intermediary between the headset and the receiver.
