Hi Liono! You know what's funny? Your comment in the same thread describing the H1 as "very upfront, brash and bass heavy" was actually one of the reasons I got them...

They
might just be very suited to my tastes (or lack thereof).
I still have no idea what to excpect though.. I find the XBA-4 to be completely unfit for music with even the slightest hint of distortion, making them effectively useless for about 95% of my collection (for the remaining 5% they're absolutely brilliant). On the other hand, I have been VERY happy with my MDR-EX500 (dynamic) and the way they rendered everything I threw at them. After four years of constant use they finally fell apart and I'm still looking for a worthy replacement. Only one way to find out if the H1 is it...
