If they are the same price I would go for the HD650 as it has a more refined and detailed sound over the HD600.  If the HD600 is much cheaper go with it and save some cash.

What do you mean by versatile? I've tried the HD 650 and have really like the tight bass but I have not tried the HD 600 so even though it's timbre from wat ppl say should suit my taste better I can't really risk it before trying it out myself. I did not really like the T90 even though they said it was bright and all, but I still love my HD 558.

I meant it plays more genres well. The added bass on HD650 sometimes got in the way for me. I walked away respecting it, and I recommended it to a guy who enjoys it --my dad. But the greater neutrality of HD600 is more versatile for me. It can be hard to separate versatility from sound preferences.

hmm interesting... I am rally tempted to get the HD 650 because of it's cheap price

While I do think the HE500 has better sound for most music, the HD650s do somethings better. I liked female vocals like Feist better with the HD650s. Very natural and stirring. But if you want to pick out individual instruments and index your way through a complicated song, the HE500s are better.
 
That said, do think carefully on comfort.
 
My HE500s are heavy and comfortable, but only for a limited amount of time. After a while, they start too feel too heavy, too tight and too hot.
 
The HD650s are not physically fatiguing like this.
 
If I was buying again, I would weigh comfort more heavily... =]
