I have a T50RP that I modded by adding plasticine, some cotton and removed the covering on the ear side of the drive. Even with these mods the T50RP was anemic and thin sounding, I much preferred my modded Grado SR60i but the wife always complained that my music was disturbing her so back to the T50RP I went. I decided to get a pair of the ZMF lambskin oval pads with I installed today. All I can say is wow! These pads made a much bigger change than I expected, the phones are no longer anemic, now there is plenty bass and I am hearing low end details that I never heard before in familiar music. I have some wire and xlr connectors on order so that I can go balanced.
