A popular general purpose D-Shape PTT earpiece suitable for a wide range of applications. Great for anyone that finds the ear buds on covert acoustic tube earpieces irritating to wear. A coiled wire leaves the radio and goes to a large push to talk and microphone which is designed to perform well in the loudest atmospheres. The second wire goes from the microphone/PTT unit to a D-Shape shall. The microphone/PTT housing clips securely to your vest and lies flat so it is not easily displaced and can be pressed from the front without having to grab hold of the unit.
