What's the difference between solo beats, studio beats and pro beats headphones?
Nothing, they're all just a gimmick to get you to beg your parents to buy you expensive headphones because of a celebrity endorsement.
solos are the smallest (thinnest). studio beats are just a little bigger ans pro beats are the biggest. the shapes are different too. but they are worth the money
saddly tony737 is right but i do have good news if u want studio quality headphones, skullcandy sells them, i have had other expensive brands this by far is the best even better than sony
