How does it compare to en120? I hear en120 is also very bright

It's brighter than the EN120, though foams tips bring them more in line. 2J is much more detailed and with greater upper end extension. 120 has more low end, mid-bass in particular. 2J has a larger stage with more accurate imaging and layering. 120 is more of an all-rounder. 2J is a detail monster.

NIce review, so how do these sound with Crimson and Supertramp? Like to hear as I listen to mostly Progressive stuff which can get congested with some IEM's.

Comparisons to the JVC FXH-30 please

@mrmoto050 I like to use the final couple minutes of "Starless and Bible Black" to test congestion as that jazz explosion can be a mess with the wrong earphone. 2J handles it just fine. They're good overall, but imo too cold and lean. I personally prefer something a bit warmer and analogue sounding for prog and classic rock. I enjoy them with metal, thoughI prefer brighter earphones for that genre anyway.
