So. I got these as a gift this Xmas, my old TB cans were a bit worn out.
After a bit of faffing around with the wireless setup I got them going, make sure its very light as the buttons are really hard to see, and have a rubber feel so its not really clear if its actually been pressed properly.
I found them to be a bit too tight a fit for me, and the adjustment isn't great.
Onto the sound , now the quality is far better then the old ones, but...the wifi link drops constantly, and their solution to this is to move away from the router be in direct line of sight of the console and numerous other things which men you may as well be wired.
I also noticed an odd thing happening to the sound , it was like a warped record ?...others have noted this but there doesn't seem to be a solution.
To update the firmware you have to download an App, connect via USB etc etc...all in all a proper mess about.
Verdict - They are going back.
