So just to be clear...have you burned this in, or just received them? I just got them, and it has been pretty well documented that they need to be worked-in properly. So far mine sound pretty awesome, but I foresee them evening out a bit. Bass could tighten up, and treble is slightly recessed. I have read a few reviews now that this headphone needs some decent current, and that the treble becomes more prominent as volume is increased a bit more than average headphones. Thanks for sharing your impressions!
