Thanks I live in the US and I got them from some Amazon retailer, I emailed Ultrasone on their website about if I had a warranty, but should I email the Amazon retailer I got them from also?

So I'm new, just made this to ask this question. I've had Ultrasone 2500's for about 10 months, since last Christmas when my dad tried to buy me off with them, and like an hour ago I was listening to Nine Inch Nails new album, the last song on it, which was super bass-heavy, not too much though...
