I recently scored a pair of used Sennheiser 579’s for only $20. The current drawback of these right now would be the constant smell of cigarettes since the last owner was a smoker. The smell is particularly bad with the earpads and headband. While I was able to get aftermarket earpad replacements, I am not too sure how to get the smell out of the headband.

The head band is not replaceable. Its made out of fake leather with a plush/foam interior. Any ideas on how to get rid of the smell so I can really enjoy these things?
