Summary: Initial impressions of these was a bit ho hum, but in reflection that is where these headphones really shine. No matter what you throw at them they will retain an air of dignity and restraint, and they would never do anything so vulgar as to shout in ones ear.
Summary: These are my favorite "Grados". With flats the bass is incredible. The midrange is so lifelike you are taken to the front stage of a concert. I've tried a lot of headphones and these are what I always go to and the price is reasonable. Mine are the i (latest improved) version.
Summary: The woodies have a near neutral presentation, just add a bit warmth to the sound.
Bass: Accurate and fast, the quality is superb.
Mids: A little bit on the warm side, neither too forward nor too distant, but can be a bit bright when not properly amped.
Pros: Near natural and fast presentation, musicality, wooden sound texture.
Cons: Require a decent amp, treble have too much decay.
