In your opinion, what is the best earphone under $500?

JustBeats by Dr Dre sucks. The music quality is terible. The bass is way over-the-top and the mids and high are mediocre. Although the style is okay, the design is flimsy and breakable. I owned a pair of JustBeats and after 2 days of using it, the wires snapped and the earphone was even worse...
