Yesterday, after 6 hours of continuous use, I "got used to" their sound signature and didn't find them as "empty"/thin (i.e. I was actually starting to hear bass guitar passages, and a more full-bodied sound). Still, a bit unnatural to my ears...
I will leave them running this weekend at home and test them with my home amp. (and also take some pics ;-))
Today I brought their PowerForce at work... Very nice little headphones! (cheap too!)
