Cheap Beats By Dre Studio Blue Limited Edition Headphones are great headphones, love the quality of the sound, they fit snuggly elimating all sound other than what you're listening to. 

Beats By Dr Dre Studio really deliver the beats. Great highs and lows and gives you renewed love for music.

They tend to leak more than expected and the noise cancellation is almost non-existant, so that makes them not the most ideal headphones for someone who listens on max volume all the time.
To cut it short, these are great headphones if you want to stand out and jam out. Noise cancellation and the sound leaking would be the only flaws, but if you don't mind,Dr Dre Beats are definitely for you.
