I am the original owner of these Denon AH-D2000 headphones which are 5 years old but look almost new. The only visible wear is a some flaking of the bead surrounding the bottom of the ear pads. The ear pads themselves are perfectly fine but if you ever replace the pads, that will fix the flakes. All parts are 100% original including the box and the plug adapter.
I will pay for shipping within the continental USA. Money order preferable or PayPal for additional charge.
