Pros: Sound quality, comfort, best headphones south of five hundred dollars. Seriously.
Cons: Design kind of bland, lacking the tank-like build quality of the HD25s, requires full burn-in to appreciate
LFF said it best, I just wanted to post a rating. They will take any genre you throw at them with ease, injecting fun while retaining absolute accuracy. After burn in the FA-003s surpassed every other headphone I have tried unamped, becoming the pair I reach for for almost all situations. A must buy!
