Whats funny is that the K612 pro and K702 are probably the closest of all the AKG headphones in terms of frequency response. I could swear I read somewhere that they are basically the same internally.

If I could make a suggestion for the K702s, go to crinacles website and find the graph tool. Select the K702, click the Equilizer tab and hit AutoEQ. Then hit export and load that text file into Peace using the import button. This takes away all the tinnyness.
