I'm the second owner of these headphones. They've been very gently used and kept in excellent like-new condition. They come in their original box with all the original contents plus an extra cable that's shorter in length than the stock cable--better for portable use. I never used the extra cable, but it has the same style locking 2.5mm connectors that the stock cable has and is terminated in a 3.5mm plug threaded for a 6.3mm adapter.
Shipping is free to anywhere in the continental US. Thanks for looking!
