Okay, I thought it's been established by many already that the V-Moda Crossfades leak like hell. Anyways, I own the Aviators, and I DO care about SQ. I can say a few things about my headphones for sure: A) the build quality is great, I think, and anyways it doesn't really matter since Skullcandy has free lifetime warranty; your headphones ever break, free replacement, no questions asked. B) They WILL leak sound when you're not wearing them. However, once they're actually on your head, little to no sound will leak so long as your volume isn't ridiculously high (I listen at exactly mid-volume, with no problems). And C) they're really great headphones when you consider the value inside of them. Great styling, free lifetime warranty, and sound comparable (and maybe better than, just ask some of the Aviator owners on Head-Fi) to the M50's -- which, by the way, are some of Jude's favorite 'budget' audiophile headphones, and cost about the same as the Aviators. So I would recommend the Aviators in a heartbeat.
