I am sure I look quite paranoid, now. :) This is bad and potentially dangerous. Mount the headphones in front of your ears such that is augments the outside world instead of replacing it. The Nortel unit Nitin uses (see the Nomadic Radio paper on http://wearables.www.media.mit.edu/projects/wearables/) uses speakers on the shoulders for this purpose. MoBic and other blind navigation aids use headphones designed to sit in front of the ears and deflect sound backward. Thad Starner MIT Media Laboratory Wearable Computing Project
