Very strange. It seems that the 558's have completely changed and repaired themselves over the time they were in storage. They went from producing no sound to being the best quality phones I've heard, ever, over three days. Now they're pretty much audio nirvana.
Thanks guys. Sorry I wasted your time. I was certain they were broken, I had tested them with pretty much every device capable of producing audio that I have.
All's good now! 
Hmm.. Suspicious. Was there something wrong with the plug or something? Can you exchange them for a new pair to be safe?
