I like the idea of wireless, and checked out some Sennheiser wireless phones, but my issue is since I'm going to have a cable running from my head already with the TrackIR, wth is the point in having wireless phones, and spending the extra $ that they cost, and deal with the negatives like charging/batteries, and interference and such. If they ever make a wireless TrackIR, I'll be going wireless headphones then as well.
