Like I said, I didn't really listen to them enough to form much of an opinion other than that they weren't my cup of tea. Its bass is solid as may be expected of the woofer but I don't hear the refinement that one may expect out of the other two drivers. My ears are hard to please though, there are few phones that I finish auditioning with a "bleh" these days if I don't have my full EQ suite at hand. The ones I've heard that won't make me go "bleh" without EQ can be counted on one hand: Etymotics line, Sony XBA-1 (and I've heard 1-4), Hifiman RE0, MH1C and now the Somic. The latter two could really use some bass reduction though and all but the MH1C could really use some more precision tuning in the treble.
I'm assuming you mean only midbass on the Somic? Because if it means it could use a reduction in subbass, then it just might be the perfect open can for me because that would mean it is close in sound to the mh1c, yes?
Also. Are you implying that that re0 was pretty darn close to perfection for you? If so, could you pm me a comparison of the re0 and mh1c?
I'm posting the graphs for all three here. You be the judge
Black: MH1C, Red: RE0, Green: SOMiC MH463
The Somic has the smoothest midrange to my ears while the MH1C has the smoothest highs. The RE0 has the best balance overall (but you'd probably call it anaemic bass). The SOMiC "measures" lower in the subbass but this can be boosted back up successfully with EQ unlike with every other pair of cans I tried. And because these are big circumaural cans the perceived bass impact is actually better than any IEM. When a subbass rumble SFX hits I wouldn't want to be wearing any earphones other than these
