Monkey, you should press the sides of the pads into the tape every so often. Mine lifted up like that for a while, but I was able to coax it into staying.
The foam behind the earpads? Just get new pads anyway, they're so nice and comfy, and they now come with a non-disintegrating cloth driver cover. The thing said it was to protect the stator from dust.
Oh man, after 3 weeks of nothing but dynamics, the Lambda has re-wowed me. There really is no other way to go, how could I have ever even begun to think otherwise.
Smeggy, ever think of selling modded orthos? You could probably charge a hefty sum since it's wood and you're the first in the world to make a woody T50RP
