That's great! Koss is own of the better ones out there... But! I had the old loss mv1s (running from memory here don't quote me on the model) that broke within 2 years I believe. Koss gave me a new pair of a more recent model, no questions asked which was good. Never used them in much in all those years (5 or so), took them out a few weeks ago, the plastic became all tacky, horrible, and one pivot actually broke. It's great they honor their warranty but they should really build like it was before. Replacing is cool, building durable might be better. Wonder if Koss would honor their warranty another time :p
