It's for shalow people who care about what other people think of them and what they are wearing which phone they are using etc etc
There are a lot of materialistic people these days and Dre just cashed in on that he turned a headphone in to a fashion accessory via getting famous people to wear them and the sheep lapped it up.
Well, in my opinion, I think that Dre is only yet another of Beats' army of endorsers, because I don't think he has any power in the production of the headphones other than haveing his name on them; other than that, it's probbaly it. Why? Because knowing the manipulative army of lawyers in the corporate side of the business, I don't think Dre has much of a say in it.
