Used this wireless system during a wedding ceremony. It was a clear day, mildly windy, and we were about 50 feet from the Pastor who had the transmitter. We pinned the lapel to the inside of his jacket (to shield the wind) and placed the transmitter in his back pocket. We had a direct line of sight from transmitter to receiver. This unit has great features and is built to last. Unfortunately, the audio quality sounded like a tin can. The audio was crystal clear, but acoustically speaking, it seems to be missing the low end frequency and sounds as if the person speaking is in a tunnel made of aluminum. Other than the sound not being to my taste, this is a quality unit. If it sounded better, I would have kept it. The ClearScan function, A/B antenna switching, and transmitter sync work great! The only reason why I cannot recommend this unit is because of the audio....other than that, range, construction, features are truly impressive.
