I bought these to help coaching a semi pro team. They worked great very easy to use and easy to carry in the carry bag.

Got this for the media team at my church of 300~400. Only ever need the five that I can tell. Work like professional headsets, very clear wireless audio through multiple walls and in a multistory building (through thick concrete and steel floors). Only ever use them in relative close proximity though, and just for a couple of hours so I'm not pushing them to the limit in any aspect. Only trade-off for the lower price range is a cheapish plasticy feel, and the battery door is a little tough to open and close.

Bought this for our middle school auditorium, as our ancient wired headsets finally punked out. These are awesome! The signal and volume were excellent, the battery charging was easy and quick, the batteries lasted long, and having the freedom to move about the space was so great for the kids. We are planning to purchase a HUB and add more units for more of the crew to be connected.

Bought these for use in church A/V production. Audio quality quite good - very acceptable. However, after two Sunday uses the mic boom on the Master unit wouldn't stay in the up position which turns off the mic. I fixed that at the manufacturer's suggestion. However, the micro-switch that actually turns off the mic when the mic boom is in the up position now works only intermittently. I have returned the unit for repair. With the Master out for servicing, the other three remote units are useless.I will update this review when I receive the repaired/replaced Master unit.
