These look like a promising set of cans, bringing the Tesla technology at a lower price-point.
I wonder how they compare to DT770/880/990's & T1 in terms of frequency, soundstage, 3d positioning (for gaming), bass impact, and so forth; and of course if it would be worth the premium over the other Beyerdynamics.
I'm aware of this review, but doesn't go as in-depth as I would've wanted:
