The 880s are semi-open. When I'm wearing them, but not playing anything I can hear pretty well (a little muffled, and but when music is playing just about all surrounding sound disappears) I had a friend wear them next to me, and I couldn't hear more than a whisper of what was being played. More than a few feet away, no one would notice, unless you had them really cranked.

The 770s are completely closed, if that's the way you want to go.
