The second wire goes to a small microphone with a clothing pin which is pinned to the shirt near the lapel. The third wire goes to a PTT / Microphone. Sound quality and the clarity are exceptional.
This Motorola Tetra earpiece is suitable for down sleeve, under clothing operation or can be clipped near the lapel or to the vest. This fit system works very well for security officers and door supervisors.
