Excellent sound quality, but they just don't fit over my head! :( Otherwise I'd get one right away. I think it's best for people with less than size 7-3/4 head, not my 8....
Whatever happened to Ctrl-Click? I find the one oversized left mouse button to be a wonder, and pressing Ctrl and clicking at the same time to get a right click is really not a difficult thing to do, more intuitive even.
