Pros: very sturdy build, great bass (extra nice with an amp, but isn't required), very closed
Cons: can get uncomfortable with extended listening, heavy cable
These are great value headphones for their price. You can find a set for around $50 online. I have a pair of these and a Grado SR225i and I enjoy them equally. I find their sound quality to be around that of the same level; though very different sounding.
