This is a completely unspectatcular product, in the best possible way. Unpack it, put the batteries in the receiver and off you go. Perfectly good sound and will easily drive any set of hed phones you chose, not just those included in the package.
Also included is a perfectly usable rack mounting kit, complete with the provisions for attaching the antenna to the front.
I haven't tried it in a live setting, but for use in the home studio to not have to trip over wires while moving about. I really like that the power switch is like an old TV on the far left of the volume control. That way it's easy to locate and you don't risk excessive sound levels as you switch it on.
My only complaints are concerning connectivity. The XLR / jack connectors don't feel really secure for jack connections, and the option to use a 3.5 mm plug and / or phono connectors would have been a nice touch.
