I bought a pair of ATH-M50's this week in a pawn shop for $35 out the door. They are in excellent condition and I was very proud of my purchase until I realized after I got home they had a very pronounced tobacco smell to them that is horrible. I tried soap and water and Febreze without any noticeable difference. I can buy new ear pads on eBay for $7 but that leaves the rest of the headphones with the smell. They sound awesome but I can't stand the smell. Should I sell them? Or is there some magic cleaner? The smell acts like it is deeply embedded into them. Thanks for responses.
