Cons: Needs to "burn in" for bass and quality
The one thing that caught me by surprise is just how out of balance these headphones were during the first hour. Cymbols and vocals were overpowering everything and bass was nonexistent. Now after about 60 hours things began to settle (I figure maybe another 40 for them to finish) and these headphones really have shown their worth. A lot of people said bass wasn't there on these but I'm guessing they only gave an impression on the first couple of hours or they have some desire for bass that is basically beating the crap out of you.
So in short...these probably aren't the best out there but at the 50USD range they were just perfect.
