Just a quick question, I'm wondering about the bass impact of the KRK 8400s compared to other headphones that are commonly labeled as "neutral" such as the Shure 840s, Sony MDR-V6, and FA-003/clones. I ask this because I've heard that the KRK's are "bass light" and having little to compare them to I'm not sure if what I'm hearing is what one would consider bass light or neutral. I just know that they're much, much lighter in bass than my m50s, which I know are known to have an emphasized bass. So if I did decide to eventually pick any of these up, I'd like to know how they compare.
Before Beats and the like came into prominence, bass, mids and treble were all measured by how close they could come to reproducing the sound put down on a quality music track--or a group of them. Using this old and (mostly) objective standard the bass on the the 8400 is neutral or just less than neutral.
The Shure has a mid bass hump. So it is enhanced above neutral within that range.
The Brainwavz HM5 (one of the clones) is neutral--but its overall sound is not as clear and detailed as the other two.
The M50 has a "V" shaped EQ with emphasized bass and treble, but has recessed mids. I hear it as a basshead lite can. It has a similar EQ--although different sound--to the Beyer DT 770.
