I have the V-moda Vibes in the gunmetal color (which is really gold). They are definately meant to give you that fun bassy sound, but not to the point where it feels like it's going to blow your ears off with bass. They definately sound better than my E2Cs, in that the Vibes seem to (according to my untrained ear) reproduce highs and lows much better (not just louder) and are just more fun to listen to. The tradeoff is that they do not isolate nearly as well as the E2Cs.
I noticed, though, that the cords are breaking right below each of the earpieces on both sides, exposing the bare wire within. The left side was much quieter than the right for a while, but it is working fine somehow now. The same thing happened to my E2Cs, which don't work anymore, so I guess I need phones with really durable wires (I don't think I'm being particularly rough on them). Maybe I can send them in to Vmoda to get fixed.
Basically, I'm really happy with the Vibes, though I haven't heard anything more highend or the CX300. Hopefully this helps someone.
