Pros: interesting sound signature, good highs, interesting design
Cons: lacking of bass, not for all genres
Very interesting headphones from famous HiSound audio, makers of RoCoo and Studio players.
This earbuds features big dynamic driver, optimised for great mids and highs, making this earphones interesting sollution for classical music, jazz and other "non-heavy" genres. Lots of air in sounding can bring you a pleasure, especially when paired with good amp/PMP.
From other side, this earphones definitely bad solution for metal and other "heavy" and bass-rich genres.
