The 580s have the old sennheiser house sound.. NOT the newer colored one. The 580 and 600s are pretty much dead flat, and the 650 just a bit colored on the low end. I really like all three cans quite a bit.
Stumbled on your profile due to mutual friends and your profile picture. Nice cans dude, I'm rocking the ever-classic HD580 right now. I really dig it, coming from modified grados and magnums and fostex.
Hey! I love "Take Me To Your Leader" and Doom's other stuff. Be sure to check out Madvillain and Viktor Vaughn for sure. Doom's got some really great stuff.
Nice listening variety btw
