They're my #3 DJ headphone, and one of my first 'decent' headphones.
They weigh quite a bit which may turn some people off, but they've got rockin' sound. Haven't heard them in quite some time but their strong point is certainly their bass. Removeable cable, great bass, great build quality. Their weight and size may turn some off though.
I wish I had them now to describe them in a more 'head-fi friendly' way (ie. warm, cold, flat, bloated, etc), but I can only speak from experience when I was DJing more frequently.
