Aweek® Throat Microphone Throat Vibration Earphone Headset For Two Way Radio BaoFeng UV-5R UV-B5 UV-B6 BF-888S TG-UV2 KG-UVD1P TH-UVF8D TK-3107
You can hear well with this unit but the VOX doesn't work correctly. If you switch from PTT to VOX the radio starts transmitting continuously and never stops. PPT does work though.. However this was advertised as VOX and what I bought it for.. if it will not turn on and off on its own based on input volume it is worthless. I tested two separate units on two different Baofeng  UV-5R radios
