Unlike my memory of the Bose headsets, these B&Os have a power switch that is active, meaning you can be plugged into aircraft power and still deactivate the active noise cancelling. Headsets may be in either mode when you open the case, so best to push the button to try.
I also loathe shared headsets, and often wipe them down with a Purell wipe, or something. The Bose were fine with this... the B&Os rub black debris onto the wipe. Yuck.
