Pros: Affordable price, indestructible, comfy, and fun
Cons: Cable is a steel cable. Not perfect.
Very Grado-y sound signature, but closed. An amazing portable headphone. Very easy to "personalize" with other colored pads and also very easy to disassemble. HD650 cable fits when flipped over. Amazing phone for the price and portability.
Unfortunately, comfort is an issue for some (myself included). I've had to return them because they clamp my head like a vice.
