Lightly used Sennheiser HD-800 Headphones which include Cardas Audio - Clear HD 800 Headphone Cable (3.0M) Upgrade.  (Original cables and box included.)

There is a small indentation in the cone *see picture" so I'm listing as 8/10.  Not sure how it got there and suspect they may have come with it.  However it does not affect playback at all.  I approximate only about 20 hours of usage.  (I moved out of an apartment and into a house so I no longer use or have a need for them.)
