The fake ones since i'm guessing you're getting them for the "looks" and brand since beats have nasty audio quality. But if you want good looking headphones with better audio quality for a lower price I would go with the fanny wang 2001 series (its 2001 or 2002 i forgot)
Personally, I prefer the real studios. They portray the real thing happening and helps you to learn the methods being used. The real studios are also nice to listen to since they produce high quality sound without any exaggerations.
