I'm surprised someone doesn't try and build after-market improved pads for the HD800 given the number of these phones out there.
The pads are pretty good, but I think there is some room for improvement,
such as some extra padding on the lower portion that rests on one's cheekbone.
It's funny you suggest improved pads because I thought they feel extremely comfortable already. I have the HD650 and tried the HD800. The HD800 feel lighter and wrap my ears better. If only they didn't look so funny, I might consider a pair.
