ThujanYou are right about the msrp ($649.99) being a joke . The AKG702 are $240 on Amazon and the AKG USA site has them for $279. That AKG USA site lists the AKG712 Pro for $499, but these 7XX are clearly based upon the 702. There are no AKG over the ear headphones on the official website even near $650.
