I've had my DT 990's for about two days now but I'm a little concerned about the head adjustment.
There is no tactile feed back and it doesn't stay at the right spot if you take them off. Also when they pivot left to right there is a clicking noise. They're also really hard to move down once the adjustment is at the biggest spot.

Their headband adjustment isn't the smoothest in the world and it surely doesn't stay in place a lot of times.  Also, the cups do tend to give a loud popping sound every once in a while as well, but that's all normal for a Beyer can.

dt990 pro?

Premium. The clicking noise is constant; almost every time I go to put them on my head.
