"Fantastic Sound and Great Build Quality"5.0 starson by mikesgroove
Pros: The music is there exactly as it is meant to be. The bass plays so true to form you can distinctly hear (and feel) the interplay between the bass guitar and drums. Mids and highs are crisp and clear -- the sound is superb with no amp necessary.
Cons: The cord is a bit thin, but 100% replaceable and can even handle a thicker gauge if you are so inclined. 300 is a lot to spend on headphones.
Summary: They are comfortable to wear and listen to for extended periods of time. Nothing is forced, and they produce incredibly accurate sound.
