Pros: amazing SQ, tight bass, very detailed
Cons: seems to get rather confused at the top end. lack of bass impact
i got these for Christmas 2011, they where excelent out of the box. even compared to my Senns they are amazing, they sounded incredibly detailed next to my PortaPros and even my Senns. the soundstage isn't quite as good as i would like, but this is before burn-in. i'll give an update after burn-in in a post later.
