FYI, warranty is 3 years.
Do you have a source for that? I believe you're talking about the Minelab warranty, not the Koss warranty.
I talked to the factory a year ago and was told every headphone made after July 1989 had a lifetime warranty. I'm not looking for an argument. I just want accurate information for everyone.
Here's the email I received from the factory on 2/16/16.
"Thank you for contacting Koss Stereophones!
