That would have required more work :P However I have my doubts about that but I don't have another one to test it out on and don't think I have the patience to try it again. However it does seem that there is foam on there as well so not sure how much different it would really make. Maybe someone with two T50RP can try that out :p I'm pretty happy with this configuration right now.
As for stock and O2 pads the comfort is on another level with the O2 esp since it is much thicker. I do recall sound stage being better on O2 but I'll try it when I get home.
