Beats by Dr.Dre is far too overpriced.
Skullcandy breaks very easily.
Beats has pretty much standard audio quality and the Solos are craps.
There are other cheaper and/or better headphones like Sennheiser, Sony, Vestax, Phillips, Sol Republic, Superlux, AKG, Bose, etc.
It really depends what you are using it for. (Listening in the bedroom/public/producing/DJ/etc.)
If you're buying it to listen to music while in public, try searching the headphones with noise cancellation. It reduces/removes unwanted ambient noises.
Or buy earbuds ffs.
