Still missing sub-bass for my taste though. Plus the firmware was updated to 2.2.1 (at launch it was 2.0.6) which potentially brought some improvements to the sound. No creaking when moving my head on this unit. One of my original knocks against them was that they would not stay on my head.
My new unit actually has clamping force which means I get bass, stability, and isolation.
Ok, I have a confession: call me crazy or stupid, but I actually impulsively bought Studio3 again when I saw Shadow Gray was on sale for $249.99 a week ago after trying it out in the store and noticing I was able to get a better fit than I had previously.
