Comments about Nady UHF-4 Headset Wireless System:

Outstanding product performance compare to our other current wireless include our expensive lavalier style that our pastor uses and also compare to our 4 wireless hand heald that our singers use. My only complaint is the small screw and related parts for adjustment of size for the wireless headset. That part should be redesign/improve. Otherwise, no other brand can beat this product for the price.
