Huh, what's with the reviews... would be better to make a thread on those and paste the post URLs.

Also, I agree with those. Except that the bass quality of the Momentums leaves a slight bit to be desired, specifically subbass. These aren't planars. Sony's, even more thanks to the annoying midbass hump, but at least it has some air.

I haven't heard UE6000.

Momentum sound kinda like Hifiman RE-400 or RE-600 (IEMs) - without equalization, it's dark and boring, but very detailed.
