I like how you called these (functional) or (defective), rather than the (good) pair
As usual, driver matching is all over the place on this Ultrasone. No wonder the imaging on Ultrasones are so weird.
@extrabigmehdi -- depends what you find enjoyable. These definitely aren't audiophile caliber. These are for people who put 15" subs in their car and EQ the bass all the way up, or people who go to techno nightclubs wearing Versace shirts with the first four buttons-undone.
The tonality is weird, that ringing at 6.5K (and the 12.5dB peak there too) is VERY noticeable.
I have a pair, that i keep around to listen to EDM. The bass is overblown as hell, but oddly satisfying in a sadistic sort of way.
