Just what I expected, good noise reduction, good sound quality.
Now that I've got it in my hands, it's very pleasant when I'm out and about in town, the general hubbub disappears, or at least is greatly reduced. And the noise reduction also works in wired mode, which is perfect for when I'm working on my computer.
It does hold my head, and slips a little when my head is tilted down, but less than my old wireless headsets. The first few days I had a little pain where the headband pressed against my head, and when I moved it back a little, the pain disappeared.
