I ordered a pair of Extreme Isolation Headphones from them that were S&D. Like $25 off, and the only difference I've noticed is they weren't in a bag inside the box and the sticker (like the one you'd put on a guitar case, because it serves no other purpose) was missing. Cable was still coiled and bread-tied like a brand new pair. I was pleased.
Yeah my guess is there might be a small nick somewhere, it was a floor model, or the original packaging was damaged. It has the full manufacture's warranty so I think it should be all good.
