I wouldn't be surprised if the counterfeit headphones sounded better. That's how bad beats is.
No they're not. About the only bad Beats headset was Solo (1st edition). It just sounded too harsh and V-shaped. Solo2 is one of the best headsets out there and it's also one of the most popular ones.
But don't take my word for it, read what Tyll over at Inner Fidelity says [1]. He trashed Solo but loves Solo2.
I have around 15 different cans of various manufacture and I do enjoy Beats especially for energetic music. When I listen to classical, I still prefer my AKGs or Sennheiser HD 800.
