Pros: Well-built, relatively cheap, comfortable, good isolation
Cons: Sound is only so-so
I got these phones used with a broken plug which I had to fix myself, so I have no idea what kind of life they had before they came to me. That said...
You can do better than these phones. The sound is good, there isn't any particular strength or weakness upon which I will extol. To my ears, these are jack-of-all-trades-but-master-of-none. There isn't any particular facet of the sound which is outstanding but none which is awful either, they're just sort of...meh. Unexciting, but fine if you just want a quick listen and aren't going to be paying much attention.
