Do Dr. Dre Beats Studio leak as much as they say? Is it noticeable on a plane or in a car?

I am wondering, a 1 on 1 fight.

Are they really cheap at the outlets in LA and Vegas? Want some, probably Studios or Solo HDs.

Use two descriptions to describe both Genres.

I saw a few videos, and heard a couple songs, such as a track on the "King of Kingz" mixtape, with Justin Bieber doing rap. I don’t think this is a bad thing necessarily, but can you take that seriously? When he first started out, he was singing country love songs and playing the acoustic guitar (not to mention he’s from a rich area) and he’s on this rapper persona now. Being a huge fan of hip-hop, I don’t really like it, but what do you think?
