V-MODA still makes the Crossfade LP, and that's definitely a bass-heavy headphone. The M-80/V-80 has some bass emphasis, however milder, and mostly (to my ears) in the lower bass range--significantly more resolving/refined than the Crossfade LP I have here, and with minimal (if any) effect on the mids. So, in a much more audiophile-friendly way than the Crossfade LP, the M-80/V-80 has some bass emphasis.
So, please tell me, how will the sound of the V-80/M-80 compare with the sound from the (I'll use the word "original" here, to appease the masses) VIBES?
Also, on a slightly different note, do you consider the Vibe Duo to be essentially the same thing as the (later generation) VIBE, but just with a mic and remote added to it? In other words, is the sound signature basically the same on them?
