I'm wondering which of those is best for dubstep and pop music? I'm also wondering which of those has a better build quality/materials. (Preferably more metal and less plastic) I know the M50s are pretty good as they are the limited edtion and come in a metal build. Sound isolation and comfort are also small factors. They are all from $150-$200. This will be my first pair of audiophile headphones, I currently use Shure Se215 IEMs with a sansa clip+. Btw, I heard that the m50s had a previous version that came in a different colour box and apparently it was much better. Can you guys let me know more about that? Thanks for your input.
