AKG 712 pro is made in Austria, 100%, and they wrote it on the headphone...I think, looking at 7XX cost, that it is made in PRC....otherwise they would have been very proud to state on that headphone "made in Austria" as well....but does it realy matter...if the sound is good...who's care about.
I own the 712, and will be happy when i will get the 7XX
