When I FINALLY was able to set these up, they seem to work well. The instruction sheet was awful!! Step one - establish necessary connections. OK, and those would be???? There should be a description and picture of each component - I'm clearly technically challenged, but it would have saved me some time to dig out the power supply for the transmitter had I known it was in the box! The charging cradle feature is great, had it been explained more clearly. Set up shows only to connect to audio out. I know there are several devices you can use these with, stereo, TV, PC, etc. Would it be too much to ask to show some set up options, say with a home theater system, or to mention that you may have to turn your TV audio down so you only hear through the headphones? My initial impression of sound, range etc is good, but honestly I'm too frazzled from the frustration of setting these up with useless instructions!
