I happen to audition quite a lot of headphones during my stay in Singapore last year(actually end of the Dec 2012 xD). Out of all the headphones I tried(that includes HD800 with Beyerdynamic A1), I prefer AKG K550 the most. It's precious details & soundstage are excellent. Not to mention it's extreme clarity & I heard no sibilance/hisses/grains throughout my roughly 45minutes audition with it. The entire frequency sound fantastic to me. Right amount of bass (something very rare to me as I dislike too much bass or too less bass or lack of controls)
Everything, was ruined after seeing AH-D600 online. There's plenty of great reviews. Just wanted to see if the AH-D600 does everything better than AKG K550. If not, is there anything that sound better than K550 at most $500? Closed design.
