Honestly, these headphones will never be as good as ones where you DONT pay for the endoresement.
I had a run in with those Dr.Beatz headphones at bestbuy. I tried them on and listened to couple of songs on the sample station. Well I had not looked at the price of them, and before i did I took a stab at guessing it. I looked at the headphones and decided the plastic was cheap, the overall construction did not give them impression of durability, and the drivers/speakers themselves sounded like some idiot put a subwoofer in each ear without any attention paid to the ACTUAL MUSIC. I guessed 30-55 bucks. I was shocked to see a 200+ tag on them.
If they are endorsed by a rapper, there will be bass. And hey, more bass.
Who needs mids and highs in the music these days? Certainly not me, the listener.....
/end sarcasm.
