Its Time to upgrade!

I have the superlux HD668b they sound well , but the clamping force is unbearable. Im packing up and going back to sennheiser. (I had the hd 419 prior). I saw the HD 518 and they seem pretty nice they also have the velour pads which are AMAZING! Does any one have these headphones ? For 79 buck they seem like a good purchase.
