Here is the ProComm PSM4NC amplified noise canceling microphone. There is not to many amplified noise canceling microphones on the market except for the well known Astatic Road Devil RD104E. It is built and designed fairly well. The cord is light and flexable. It has a cool blue key up light. The gain control is tucked away at the top and the battery compartment is easy to use. The performance was fair on my equipment. I would say it was slightly on the muffled side with my voice. As with any microphone it's a matching game. Some many variables with the radio to colorize your voice along with the microphone, Bulldog.
