Thanks - this is all super helpful.  My headphones sound outstanding, I sure can't detect anything wrong with them.  I'm just gonna assume it was the minor glue issue and enjoy rocking out to these moving forward!

Thanks for sharing, that's super helpful.     Well as feared, mine is a Gibson.  I pulled the earpads off and I do have some glue residue.  BUT - as far as I can tell the headphones sound great.  Would it be clearly obvious if something were wrong with them?  I assume that's the case, but...

Cool - I'll grab the box again.  Specifically where should I be looking?

I'd be looking for one as well. Any leads?

I just received my set from Amazon Warehouse Deals today.  Is there a quick way of determining if these were manufactured by WOOX or Gibson?  I believe the Gibson ones were the ones with the issues, correct?

Sweet, that's good to know.  So there should be *nothing* wrong with the actual headphones as far as sound quality?   I'm really looking forward to these!  After a ton of research and comparisons I feel like these are the right ones for me!

Oh wonderful, I literally just purchased a "Used-Very Good" set from Amazon Warehouse today. What sorts of issues do I need to be on the lookout for? Should I ditch the whole order?
