There might not be I might just be a little paranoid over it. By original box I meant the black carry box it came with it, there was no outer shell that was included.

I picked up a used pair of HD 600 and I was wondering if I got fakes. I'm 95% sure they're genuine but some inconsistencies lead me to believe that they aren't. (came in original box with instructions) They're the marble finish version they don't have a "made in Ireland" on the inner headband...
