This is the best companion for outdoor communications with your HAM friends in war game, paintball, training, hunting, motorcycles. Perfect for security/surveillence purposes too. With this 2-wire throat mic, you could get rid of the background noise when communicating with your partner. Different from the traditional microphone which transmits sound wave in the air, the throat mic absorbs vibrations from the throat and transmits them to the ham radio. The magic comes like this: Mechanical vibration from throat => electric signal => transmitted to radio transceiver Since the microphone transmits directly from your throat, it is not sensitive to your background noise. This is exceptionally ideal for usage in high ambient environment such as driving, riding motorcycles and bicycles. With the best-quality transparent acoustic tube that could hardly be detected by people around you, this is also perfect for surveillance purposes and security at airports, casinos, crowd control at conventions and concerts, and any working environments requiring discreet communications. The throat mic could be easily hidden under the collars too.

Snug Fit Transparent Earbud: The earbud is designed in a way that fits your ear canal and it is hardly detected by people around you. Fine Transparent Acoustic Tube: Connecting directly from the throat receiver, it is perfect for discreet & clear communications.
