HD-668 B : Excellent speakers but uncomfortable headband

Ok, so first of all, they sound pretty good, and I dont get the sweaty ears with these like I do with the closed speaker models... If only the headband was more confortable, I could wear these all the day...

But I can't. The headband design is utter crap, I guess I just have too big head, because those "self-adjusting" pads will completely move out of the way and those plastic bands will leave deep grooves into the scalp. I'd have to switch their position all the time to get rid of that.

If the headband was better, I'd give them 5 stars for comfort.

First I thought that the semi-open design would eat away the deep bass, but it won't. I've just had some bad experiences with some other cheap open headphones. What the semi-open design actually does, is that after few hours of use, my ears are not sweaty at all!. And they won't block outside sounds, and I can hear stuff like the doorbell, phone ringing and even my tv, when I have the headphones on.

What I really like, is that the cable is detachable, there is the headphone plug right in the headphones... So I can use my own cable with volume control. Also it makes the cable easy to replace, if I accidentally destroy it by running over it with my chair.
