I personally haven't tried the 550 Pro, but from what I've read is the 550 is a more versatile headphone with a wider soundstage while the 580's have richer, deeper bass response. I have the ATH-M50 and the 580's are very similar, but the bass is much cleaner and deeper, where the ATH tend to get muddy.. I'm not an audiophile and I've used this setup with my Cowon D2 and have loved it.
