I'd hate to bump an old thread but, after reading this persons comment on a lot of bass heavy headphones, I'm now unsure again.

After some listening, I feel my monitors acutally have enough bass, it was just that I usually listen at a bit lower than normal listening levels. I listened to a particularly bassy Drum and Bass track "Break - Mason", and took in a thought from the members quote about the fact that if you have really bassy source material and really bassy headphones, it can be a bit overpowering. My speakers have have a level of bass, that sounds fill in, and you can notice for sure when bass comes in. But it's not to the extent where it makes it hard to concentrate on other frequencys.
I guess after this I've found out, I'm not particularily a basshead as I've only figured I have enough bass with my studio monitors. I'm not needing a headphone that has subwoofer bass levels, because my source material has excessive bass anyway; I just need the bass extension and clarity. Is this correct logic? I definitely want to hear it, but I don't want subwoofer bass.
To clear things up, I thought the HD 515 even had too much bass (albeit sloppy bass) playing some mainstream techno. I never hear of these phones being bass monsters, I'm not sure how my speakers compare.
But, in a nutshell. I feel I don't need massive bass quantity, but I'd like good extension and clarity. I once tried a AKG K601, and found that all of the highs, mids, vocals etc were outstanding and exciting, although the demo was playing Snow Patrol, they just didn't have enough bass, a bit more bass weight and it would have been great, seeming as Snow Patrol isn't particularly the first thing a basshead will listen to. I then tried a pair of Shure SRH-840's, and while they had the bass, they just were no where near as fun to listen to, and I found them very boring.
I think Sennheiser is the middle point here, but I heard they are darker and etc than AKG's.
