Equipped with a twin plug to fit Motorola radios this Earpiece and Microphone is an essential piece of kit. With great sound quality the earpiece fits over the ear and remains comfortable for long periods of time. Also very hardwearing and unlike some other headsets is unlikely to snap or break with moderate use. The microhphone was very responsive and voice transmissions can be clearly heard in a range of different environments. A very good useable earpiece and microphone for most major twin jack PMR walkie talkie radios.
