I bit on these. It shows OOS online but I went into a store today and they had a couple of left, so anyone looking to get these should check their local store. My store had one in matte black and one in shadow, I got the matte black one.
I'm not an audiophile by any means. In fact, these are my first "real" cans. The only headphones I've used before were "gaming" headphones from Logitech and Corsair. I'm enjoying these a lot so far (only been about an hour). My three sources are my PC w/ a Creative Titanium Fatal1ty card, my iPhone 6 and a late 2013 model Macbook Pro Retina. Going to give them a few days to burn in but I think I may pick up a DAC for them somewhere down the line.
