Feature: 1. Remote microphones with button calls can be used anywhere. 2. The microphone is transmitted directly from the throat and is therefore insensitive to background noise. 3. It is difficult for those around you to find the best quality transparent tubes and protect your health from the effects of radio radiation. 4. This is very suitable for high ambient conditions such as driving, riding motorcycles and bicycles. 5. It is also well suited for crowd control at airports, casinos, public places and concerts and for surveillance purposes and security in other work environments that require careful communication. The throat microphone is also easy to hide under the collar.
