I got my pair of RX700 today. Couldn't find any foam, so I got a $3 sit-mat at the local store, and it works wonders as pad stuffing. I like them even better now! Did any of you find them sounding tinny at first? They sound metallic echo-ish in parts with 1-2 instruments (more instruments obfuscate the echo), compared to my Sennheiser HD202. They improve on the HD202 on other areas though, I just realised they have no sound stage, and I can hear bass guitars in parts I didn't know there were any. Comfort is nice too, although I certainly feel their weight on my head.
