Not bad, but two points that bother me: bass extension is extremely poor. Electronic beats are unbearable and the overall resolution is too low (not for the price, though).
The Z1000 will fix both points, I guess! Might be really sweet.
I also didn't know there's an iPhone version. I really want that instead! I have a girl who's in Japan right now. She could get the iPhone version for me. Hmm...
