I actually found this really well done tutorial and used a similar method to fix them. I did the left side while I was at it. :)http://www.head-fi.org/t/665349/sennheiser-hd25-fixing-slipping-slidersNow I just need some new pads, the sound does not appear effected from the slightly missing foam padding. I will replace them though regardless eventually.
