These are terrible, terrible headphones. The bass is far too loud, bloated, and inaccurate. The mids aren't great. The highs are absent, and when EQ'd in they're still quite terrible. Comfort is sub par. Durability: my pair broke after 2 years of light use, and they'd been cared for well. I'm told the new version fixes this, but check that before you buy - if you're stupid enough to buy them.

The only things these things have going for them is the Sony label (which some people equate with quality), and that they look pretty good.

Avoid these headphones at all costs - there are much better headphones around for the same or less money.

being a basshead and a turntablist, i bought these industry standard headphones 7 years ago and have used them at every gig, for every mixing project, and on every flight i have taken since.

they are very portable, and can be folded a variety of ways in their provided bag, but not nearly robust enough. the swivel joint above each cup started giving out a long time ago. they have been held together with various things; twist ties, every kind of tape, super glue, gorilla glue...

the swivel joint finally busted irreparably, so i had to move on... it's a shame, because the drivers are still very loud and clear.

as far as sound, the bass is really pretty great for DJing, extending into frequencies rarely covered by $100 headphones. the highs are also very loud making it easy to hear the high hat and snare while beat-matching. that being said, 2-4k can be very harsh and semblant. there is very little soundstage, but provide a very close and loud presence. the highs don't extend enough to provide any spacial relativity.

these cans are easily driven from mobile devices, and offer nice portable listening for hip hop and electronic music.

i mix and travel much less now, so i switched to a less portable, higher fidelity headphone that offers the same deep bass; the Beyerdynamic dt770 80ohm

I'd owned the V300's for quite a while using them for musicians in my studio, but they break easily from reckless musician use, so suddenly I was without an intact pair of headphones, so I bought the V700's, since they are the best Sony headphones available in Sweden. I tried everything from Sennheiser to Beyer to AKG before deciding on these.

I especially liked the bass response, which is way better than anything I've heard before. The mids are very clear and detailed, and the highs are really good. I use them for everything from leisure listening to professional studio work.

I've just ordered a pair of MDR-7509, though, so these are probably going in the drawer for a while.
