Despite cute's malicious and insensitive harassment, I will fulfill this request. xD
So, when I do comparisons, I like to listen to take notes on both sets.
My Notes: For People who are Interested in That Sort of Thing (Click to show)
Bitch Bad- Lupe Fiasco
JVC HA-S500:
Low Eb (40Hz?) not present
Middle synth hidden
Hi-hats super-obvious, but not sibilant
Especially great with snare/hi-hat rolls
Somic EFi-82 MT
Low Eb present, but faint.
Middle synth still hidden, but louder.
Vocal layering in chorus jumps out in a pleasant way.
Background snare rolls obvious, but not "sparkly".
Levels- Avicii
JVC-HAS500:
Kick drum at :34 dominating
Hi-hats inside of synth obviousLead synth gets nasally
Loud reverbs until 22 seconds.
Kick Drum has very heavy sub-bass presence.
EFi-82 MT
Lead at forefront in intro.
Hi-hat inside of synth hidden.
Lead synth gets slightly nasally.
Reverbs sound more atmospheric.
Kick not sub-bassy at all, bass is at head of low-end.
Adorn- Miguel
JVC HA-S500
Kick drum has no mid/treble presence.
Bass about 40 degrees. (use the top line of numbers on a protractor to find the positioning)

Here's the relative soundstage of the two sets. I thought that this would be a decent way to show it. This is all subjective, mind you. I didn't actually measure it with anything but my fingers and a protractor on the screen.

To my ears, the JVC was more of a fun, consumer signature, while the Somic was, while definitely engaging, more of a neutral set. The JVC has deep bass and a bright treble, but often fails to represent vocals well for this reason. Also, with the overtone series being a thing (TL;DR: the timbre/tone of voices and instruments is created by very quiet frequencies, usually in the mids and treble.), a lot of instruments just sound..off. Basses get bloaty, drums get sparkly. Still, for electronic music and a fist-pumping portable (at $70, nonetheless), it's a great deal.
The Somic EFi-82 MT, on the other hand, is much more balanced and mellow. Instruments are right where they should be, tone wise, due to a fairly neutral (if slightly dark) frequency response. Soundstage, like the diagram mentions, is superb. Additionally, the Somic's excel with vocals and have a certain "airiness", for lack of a better term, on well mastered tracks. The treble is very utilitarian. It gets in, gets out, doesn't sparkle, shine or do too much. The upper mids, however, get a bit bright, but are never fatiguing.
The EFi-82 MT has a longer cable (without extensions), but the JVC-HAS500 has a very nice L-jack. At this point, it's just nit-picking, but the JVC HA-S500 does feel a bit better. I dropped my Somic once and it made a very nerve-wracking sound. Fortunately, it's OK, but I will definitely baby them in the future.
Feel free to ask questions.
Thanks,
Will.
