This is an excellent, quality, well built microphone. What you come to expect from Motorola. The audio quality is crystal clear as well as the transmit side of it. According to signal reports I have received. I especially like being able to change channels from the mic and adjust volume as well. The man down feature on the mic is also a huge plus if your a first responder, very easy to manipulate. Very solid and positive click adjustments. Overall this mic is hands down the best shoulder mic I've ever owned, I should know, I have over 27 years in law enforcement and dispatch comm experience.
