I saw two cracks on my Sennheiser HD800 Headphones cable today. I really didn't do anything to cause that. after looking closely I saw many small cracks on the cable. cable sleeve is cracking and making the cable naked. some parts of the cable is without cable sleeve now! I'm not against HD800 and I love its sound quality. I know I can buy another cable but that black sleeve shouldn't crack and tear down like that without any reason.
