Pros - I personally feel the overall sound quality is rich. The low frequency is superb
Cons - The cable is very thick and not pliable enough. As with all in-ear phone, these MUST have a perfect seal within your ear canal or they sound like a $10 pair. The volume controls are too high up the cable, I am constantly searching for it as they are out of my visibility.
Note: These are far better than my Bose ME2i; however, my Klipsch S4i are still among the best sound I've heard.
