Pros: price, sound quality, build quality
Cons: ok design, the 558 and 598 look much better
Sound stage is average, but separation is awesome. Some people clam that bass is lacking, however, I think the sound signature is absolutely great.
Sounds good even when driven by laptop and phones, full potential easily achieved by using $300-500 all-in-ones. This headphone uses the same driver as 558 and 598 but the outer shell and ear pads aren’t as good, that is the only down side. But you can't expect too much for $80.
