Pros: Very neutral sound. Great build quality.
Cons: Ears get hot after a while.The only thing not built well on this headphone is the earpads. When mine gave out, I bought the Beyerdynamic velour ones.
This headphone was my first high quality one. It sounds extremely neutral with good bass that is in proportion to the other frequenciencies. The midrange and treble also sound natural. What this headphone lacks and what you get by stepping up to the Sony V900HD(aka 7509HD) is a higher level of midrange detail. For the price though, this is an excellent value, however this is not on the level of the 7509HD or CD1000.
