B stock Sennheiser 600 and 650

I bought B-stock HD 580's way back in 2000.  As delivered, the headphones had a cutout in the left speaker.  It was caused by the cable not having a good connection.  I pulled the cables, carefully cleaned everything and reinstalled - no more problem.  I still have the phones and they still sound pretty good.
Make sure you are getting the factory warranty, but my experience with b-stock items has been good.
