Sound quality excellant, you can whisper and still be heard
None so far
I originally bought a Fire Fox Throat Mic which did not work at all, poor quality, so I recently purchased the U.S Special Forces Throat Mic what a difference night and day. I can whisper and still be heard on the other end. It fits very comfortably and the sound quality is great
RAP4 is AWSOME!!!!!!!
Highly reccomend this product don't waste you money on Firefox
