It works out of the box. Audio level is fine. No distortion, very clear. Audio response is flat. It is not filled with high or low frequencies. No motor boating. (RF getting into mic circuit) Well worth the money.
This mic is solid and sturdy, and has a small PTT button. It has good audio out and good mic pickup. Adjusted the mic gain a touch lower on the radio to avoid overdriving the audio signal. No lights or bells and whistles but appears to be waterproof as well as rugged.

Used on my Tytera MD-380 radio in DMR mode on DMR Simplex frequency 79 and no issues at all. Very loud and clear. Plugged into a Baofeng UV-82HP and there is a noise that you hear thru the mike when you release the PTT. Not sure what it is, but I will be keeping this mike with my MD-380.
I needed a Mic for my MD-380 and heard that this was the best way to go. It is indeed an excellent mic as well as a better speaker than what is in the radio. The value is excellent. On top of all that their service and response was an added treat. I would do business again with Connect Systems.
