Z Review - AKG K7XX
If you can't afford the Austrian Made K702 65th anniversary cans [http://amzn.to/1NG8vIx] Then you can get the Chinese equivalent of them on massdrop [http://goo.gl/Vio6Qi]. Sold in batches and usually for a limited time these are some of the best open headphones I have tried. Most comfortable and just silky good sound.
