I think the answer is a yes.
Well, pulled out both earphones, and did some a/b'ing, source Cowin Z2 (no effects):
Dylan's - Duquesne Whistle - (folk)
40's - sound natural, no obnoxious thumping or other sign of bass bump, Dylan's nasal sound is perfect, folksy guitar picking is clear. Mids sound clear and obvious. Thump/thump of old style bass is part of the background as expected.
30's - sound natural as well, funny, bass is more upfront on the 30's. 30's do seem to have the better sound stage with this song. They just handle it slightly better.
Grimes - Infinite Love Without Fulfillment / Oblivion (club sound- female vocal)
40's - you want to get up and dance, really! Solid bass, pounding away, but Grimes vocals are clear and certainly nothing is lost. No sibilance on Oblivion.
30's - sound has less thump to it, but just as clear. Bass is still there, but takes a bit more of a back seat. This sounds remarkably good on the 30's. Again no sibilance that I can detect.
Tame Impala -
It's not meant to be (alternative rock/mid period Beatles type sound)
Sound starts off nice with the bass right up front, male vocals/guitars come in and are clear with nice sound stage as needed for this type of sound.
Guitars sound slightly better, vocals a bit more forward.
With the Samsung Galaxy 3 (Poweramp):
Assemblage 23 - Vinyl Sessions (club/techno/IDM):
40's - Again they show their straight with this type of music - bass and bottom end are hard hitting, yet highs are crisp and quick. Vocals are buried in the mix (as what artist intended, from this sort of music)
30's - bottom end is not quite as hard hitting, but there. Vocals a bit more forward in the mix, mids more forward in general.
Frankie Rose - Intersteller (Sythpop/club - female vocal)
40s - Again, they just grab you with this sound, clean bass that goes deep and even rumbles when needed.
30's- Funny, the bass sounds just a bit on the sloppy side, but still, the 30's handle this quite exceptionally. Mids cleaner and more upfront. Have to wonder if the 30's have a slight mid-bass bump.
The sound on the 40's is slightly darker than the 30's (as was true with the 3's and 4's), both seem to have the same detail. The 40's seem to suffer from microphonics more, perhaps because of the bigger housing (switched out the eartips to a smaller pair, and that helped some). Achieving a seal on the 30's was also easier because of the smaller earphone body.
Device comparison: The 40's sounded better on the Samsung. Output is defiantly different on the two devices, with the Samsung having a fairly strong output, especially for a smartphone.
The 30's sounded good on both devices, so to me anyway, not as source dependent as the 40's.
My recommendation, after my a/b'ing of the two, for most people go with the 30's. If you are into club/dance/techno/trance then go for the 40's, they will give you that extra kick.
Indie/rock/classical/jazz fans really should stick to the 30's.
The above are just my humble observations, take them all with a grain of salt.
I do have to say, both are excellent earphones and compare quite well with earphones in my collection that cost me two to three times the amount I paid for them on Amazon japan.
Hope this helps.
