I got this headphones on December 18,2004.As of March 23,2004,today,the headphones keep shutting down after a few minutes,the system just doesn't stay on.When I do get them to work(just for a few minutes) and turn my head the sound cuts out.There is a two year warranty,parts and labor but according to Amazon's customer service you have to address the manafacturer to honor the 2 year warranty ,and guess what?THE MANUFACTURER IS IN GERMANY.
