I use mine every flight. perfect? no. happy with the purchase? absolutely. anr = good. wireless = good. if they aren't seated perfectly over your ears you can get some wobbly, but I understand this goes with most ANR headsets (the tangos were my first ANR). you do have to develop a 'routine' that you wouldn't use with other headsets, mostly around charging them, otherwise I think they are solid and I love the wirelessness of them. I'd be surprised if they didn't have a setup at the 'kosh.
I will say that I also tried the zulu2's and those are also awesome.
