I see you use the AKG-712 Pro!\nOff the top of your head, do you know what is the difference between it and the 702?\nWell, first of all, mine is made in Austria, anything under $300 is made in China. Second, 712 Pro is very similar to 702 but prior has a minor mid-bass bump - trust me, it's not a major one, while 702 is a bit more neutral.\nOne thing I have to say about my 712 is these are BY FAR the most comfortable headphones for long-term listening I got or ever tried. \nDo they have 100% absolute reference sound? Not really, but it's damn close. I'd say 9\/10. Never listening fatigue or any hint of lack of comfort. \nBetween these and Sennheiser HD600 it would be close call IMHO.
