Such a great discussion with so many great tips. Thank you all for the posts! @onevstheworld My friend actually works in national archive, where they disinfect old books in chambers with Ethylene oxide. I will ask him if he can do this for me. This is brilliant idea, thank you! And yes, I will...

I have had an ear infection and unfortunately, used my IEMs during that time. Now I keep getting recurring ear infections and I suspect that it might have something to do with my headphones. I'm affraid baby wipes won't cut that. Thank you for your response, I have studied some chemical sheets...

I have Sony NWZ-X1050 portable player and I want to buy new headphones. I really like 250 ohm Beyerdynamic DT990. Does the Sony NWZ-X1050 have enough power to play good with 250 ohm headphones? Is that good combination? I have no amp and I don't want to buy it.
