M50 is under $100? Normally its in the $100-150 range. Out of the ones you have listed, the M50 is probably the best all around.
I would also recommend the Sony MDR-V6. It's in the same price range as the Creative Aurvana Live. Compared to the CAL it's much better built, more neutral, more analytical (thus less forgiving).
The SR60i's, I would recommend not considering them unless you can listen to them first. They have a quite strong coloring to them that some people love and some people hate.
Actually, I would say the most important thing when buying headphones is to actually listen to them. We can't tell you if you are going to like a headphone's sound or not definitely, only you can do that.
Also, any other requirements other than sound?
