Pros: Good mids, long battery life, and they are comfortable.
Cons: Lacking bass, poor response, sibilance in the treble.
If you are looking for a portable bluetooth headphone willing to compromise some sound quality for it then look no further, they are not too pricy, but i really expect more for sony in terms of sound quality. If you are serious about audio you probably won't like them. But audio is a subjective topic, so you might strongly disagree and end up loving them, that's just my opinion.
