Headset Microphones

I'm the PA guy locally for football, basketball and track. I have been wanting a headset mic for years now to clear out that room on the desk while doing games. A table top mic is right in the middle of everything and a wireless hand held mic is always on. I bought this mic and paired it with a Shure push to talk button. It works fantastically giving me instant on and off plus my desk area is free of the table mic. I also used it for State Championship football and the University of Missouri and the sound personnel there assured me this is a professional quality mic. It is a 3 pin setup and the sound quality is crisp and clear. All you PA guys out there looking for a great tool to add to your bag get this and the Shure A120S switch and you are going to be a happy camper.
