Firstly, get that woman to change her perfume. If you didn't like it there's a good chance others won't either,. this could be compared in comparison to a man with bad body odor, You need to confront her and explain what ever she's wearing is not working with some men. (think of it like helping her out) Then, after you've explained as nicely as possible tell her the truth, tell her you made a thread on a forum telling the whole world her perfume stinks! I'm sure by now she'll be thanking you x100. You'll be helping her out!
Ok the problem,
It's best to let the headphones air out, don't put anything unwanted on them, you could damage them. I recommend to speed up the process , get a warm damp (not wet) slightly damp cloth diluted in a tiny amount of dish washing detergent. (remember only a little bit) wiping them over lightly around the infected areas. Avoiding the actual speakers, proceed with caution! Then let them air out where there's a draft, it may take 24 hours to forbid the pong!
