The Eartec Slimline Double Inline PTT Headset for SC-1000 Radio Transceiver allows users to clip the radio to their belts and communicate through it. It is a mid-weight handset that combines comfort and durability. It features an internal spring steel headband that can be adjusted to provide the right amount of tension for each user. Extra soft padding ensures that the headset fits snugly and is very comfortable when used. This headset includes an inline Push-to-Talk button that is also worn on the belt or clipped to the user's clothing. This assembly acts as an intermediary between the headset and the transceiver, and affords the ease of Push-to-Talk transmission.
