Those AKG phones look very similar to my K240's, which were very natural, and didn't have the 'smiley-face' EQ curve applied, to hype the sound as you might with home-hifi bass/treble controls. I did a lot of my recording in a home-studio apartment, so I definitely wanted flat response. The Audio Technica look like they would have the 'happy-face' curve. I'd go with the AKG's, myself. Though, for studio phones, the AT's might be a better choice, as they probably seal better, so less leakage thru the phones when you're doing vocals.
