I am probably the forum's reigning expert on the sound of the V700. Or, should I say, sounds, since they go through quite a transformation when the plastic used in the swiveling hinges inevitably breaks, resulting in a poor seal. They do have a push through the upper midrange and initially they're quite dark sounding, but even in pristine form they have mediocre bass extension and grainy, unremarkable treble. They also have a tiny soundstage. As they age and the seal loosens, the bass drops off, leaving a mid-centric headphone with poor detail retrieval and obvious upper midrange coloration.
No headphone should ever attempt to imitate the sound of the V700 in any stage of its "sonic evolution." My greatest shame shall not be uttered here, since it doesn't concern headphones, but my second greatest shame is that I bought the V700 twice before I finally learned.
A "studio" type Sony headphone would be something like the V6/7506. They're not bad, though I found them a bit bright and a tad grainy, and there's a bit of upper midrange glare that's vaguely reminiscent of the V700. They have decent bass extension--surprising, in fact, for a design of their vintage. Definitely not basshead material, though. I mention it merely for the sake of reference, since it's a typical "studio monitor" sounding headphone. It's certainly much flatter than a DJ headphone of any description.
