Thus, they will be more snug than other studio monitors, high-end electrostatics from Stax or Sennheiser. Something else worth noting is that the ear cups are rather large. Not really a design flaw since all big studio monitors are this way, but a minor pain nonetheless. This is cool if your music lends itself to bass-heaviness. The mids and highs are acceptably clear, but not stunning.
Vocals come out fairly clean and tight.
I wouldn't recommend them for classical, jazz vocals or other genres with lots of delicate passages with detail, I think there are other headphones that're more suitable for you. While I think the tonal balance is skewed a bit too much to the bass, these are still a decent set of headphones. They're designed to take to lots of abuse from the DJ's they're meant for and will probably be just fine for me. The headphones look cool, with a silver-colored finish. Two words come to mind after I demoed the headphones at Tweeter, etc.
