Got these in the mail today and I can't say I've got any use for them. I love the Sony's I've been using. These cans have never been opened and I took them out of the shipping box just to snap a photo. All the info on them can be viewed here. They're $100 everywhere on the internet. Asking $80 $70 $60 shipped. PayPal money send and ConUS shipping only. Link to my heat is in the signature.
