I don't know what people's problem with Beats is, I own a pair of the Solo HD's and they are brilliant, very durable and the sound is great. Yea they are bass heavy but they also work great with other types of music, I listen to all different types of music and I love Beats.
People haven't actually used Beats they are just pilling on because subconsciously its a way for them to hate minorities without being direct about it. If Dr. Dre had no involvement with these head phones people would be talking about how great they are because of all the bass.
The tech world has become more overt in it's racist undertones. That's largely because black people have not been involved in the tech revolution as much as other minorities have.
