All the lights on the base work. It has been stored for a year and when I took them out the headphones just didn't turn on anymore even after charging for days, and trying brand new batteries. I'm thinking about openint them, or shipping them back to sennheiser but I don't know if that would be worth the money. Thanks for your help

I opened them and nothing seemed wrong inside. I think the problem is in the switch which is stored in a small metal casing. I shipped the headphones back to sennheiser yesterday without giving my credit card info so they give me a quote first...
