I purchased this new about 10 years ago. I am selling it because I haven't used it much in the last few years. There are no operational issues, and while there is some wear and tear on the main unit, I think it's generally in good condition. The ear pads and headband were severely deteriorated, so I replaced them with generic third-party ones. Please replace them if you are concerned. The cable had deteriorated badly due to hydrolysis, so I repaired it with heat shrink tubing. It can be used, but I recommend replacing it. The headphones, cable, outer box, inner box, and instruction manual are included. The outer box has some scratches. The inner box is in good condition. The inner box has a unique smell, but it has been there since I purchased it. Used in a non-smoking and pet-free environment.
