How long do you think before pads need replacing? MY HD650s aren't that old, but get lots of mileage as I wear them 5-6 hours per day when working from home. Looking at them, I think they're looking a little flatter than when they were new, but not sure if I'm just being (mildly) paranoid.
EDIT: I guess I could just measure them and compare with the figures shown above.... duh!
I was just trying to reiterate what other posts on Purrin's site were saying that the pad design (material) got changed sometime along the lines and old/new drivers saga is just old/new style pads as it seems. I have no idea how long the new pads with stiffer foam will last.
