When I took mine off 'Type A' was stamped on the inner part of the pad. It wasn't easy to make out but it was there. So, you could try that. They're easy to remove and replace. But if your HPs are Sonorous like mine rather than Pandora I'd better a few pounds you have the Type A which I believe are now stock for the iv and vi. The type B pads I mentioned in my last post are the ones from the original run of Pandoras and are the ones most folks prefer for SQ, if not comfort. But as I said, I can't promise they'll keep the sound anymore "in".
