Maybe like many people who bought the Beats Studio, I was amazed by the very stylish look of it. My first pair of headphone was the old Beats Studio, and at that time and still now, it's one of the most stylish headphones on the market!
That's been said. As for the sound quality, my first impression of the old and new beats is the same: They do NOT worth the money for the sound. The lows are very impressive, but the mids and highs are not very good.
This new beats has definitely improved over the old ones. It can pick out all the major details (NOT ALL) as it claims but then boost the sound of every detail up so you can hear it "clearly". The result is a big chaos in music, no layers, no depth, unnatural and harsh on the eardrums.
So, I would say, Beats Studios are for those who like heavy bass music and influenced by its heavy marketing. Otherwise I would highly recommend the Sennheiser Momentum which has a far better sound quality but lacks of bass (By the way, it's German!).
