Sennheiser HD 559 Ear Pads

I bought these for my HD569, I read somewhere that they would fit on these headphones, even though it doesn't mention that in the description, and they do indeed fit perfectly fine. The surface is made of what I believe to be some type of velour, which is very comfortable, and the foam inside of them is harder than the foam on the stock pads, which is nice, as previously the pads would compress so much the drivers were pushing up against my ears. The foam does get softer when you wear it for a while, I think this may be due to the warmt of your skin heating up the pads, which makes them even more comfortable to wear.
