I would just like to say that I find the bashing of Beats and Bose to be rather hilarious.
It's kind of in style to say that these products are terrible. The lion's share of people bashing the two brands have never even listened to a pair of either, they just know that saying disparaging things about Beats and Bose somehow qualifies you as an "audiophile".
I've got a pair of Beats Pro and I also have a pair of PSB M4U 2 (the PSB, IMO, is the best headphone available in this price range)...while the PSB definitely boasts a bigger soundstage than the Beats Pro, the Pro is very, very good and this cannot be disputed by anyone who has listened to the product.
I have not really auditioned the less expensive models in the Beats lineup, but I would have to assume that many of the opinions of Beats come from dissatisfaction with the Solo or Studio line. Anyone who says that the Beats Pro is junk simply doesn't know what they are talking about or they are trying to make it appear that they have an uncommon discerning ear.
FWIW, if you can pick up a pair of the PSB M4U 1 or 2, I think you would find this the most pleasing set of headphones available for under $400.
