Want to clear up a misconception here on headfi. I just spoke with Pete Carini, Beyerdynamics USA, about warranty repair on headphones purchased here on headfi. My pair was purchased used from another headfier....even though the repair is withing the two year warranty, the warranty is void for the second owner and beyond, even with the original receipt. Warranty is only valid to the original owner/buyer, so buyer beware. This applies to purchases from Amazon Warehouse as well, if these were sold to original buyer, then returned to Amazon, and Amazon sells them at a reduced cost as, like new, the warranty is invalid. Sennheiser, Beyerdynamic, AKG, etc, the same policy applies.
Thank you for posting this. I really appreciate it. I am actually testing out my DT880s TONIGHT. Finally! I bought them over a month ago from a fellow head-fier but I had them sent to my parents place.
