Pros: Amazing sound. For such small headphones they have great bass.
Cons: To get that sound, you have to somehow trick them into staying put. The buds, no matter which dampers are used, just don't sit right in the ear, leaving you hearing background noise and losing all the bass. After extended wear (2-3 hours), they are very uncomfortable. The stiff cord makes a lot of noise against clothing and also tends to not allow much motion without losing the buds again. Love the sound, hate the design.
