Hello friends, I recently called a dance and had trouble with my Shure wireless headset system. I had feedback as I called from the floor/field. That indicates that the mic pattern is probably to wide, since the volume was not that loud. It also droped out as I walked around the field at the outdoor dance. Can anyone recommend a good quality headset system for a singing caller who is often on the floor as he calls? Rich Sbardella Stafford, CT
