EDIT:
Just a quick heads up. There is now a seller I found on ebay that has replacement velour-type pads for these. It says 681 but pretty sure the things would fit the 662's also. Measurements are the same and can housing is the same from what i can tell. Now you don't have to spend a fortune buying akg ones to find out they aren't going to work for your sound signature preferences, you can do that later
. That wouldn't make sense as It had been stated to spend half or more of the initial can cost again on the other replacements available. I may try them eventually.
