An MP3 style earpiece for covert use. This looks like the earpieces you would use on your mobile phone or MP3 player, so it looks like you are listening to music. Comes with in line microphone and PTT. Suitable for use with Motorola walkie talkies that have a two pin socket such as the GP300, XTNi, CP040 to mention a few. Light weight so comfortable for low periods of use.
