I don't particularly find the N4 lacking in the bass region for a fairly neutral and balanced iem. Definitely has better body and harder impact than leaner iems like er4s and b2.
Also, I have no issues with the fit - I think I have enough space left in my ear for a 10-driver universal iem.
(btw in the pic the N4 is sticking a bit more from my ear because I'm using it with tri-flanges)
Also, I was just messing with some tips and the small meelec S6 tri-flanges give me a pretty good deep fit and seal although I'm still undecided on the sound with them. Tip rolling is quite a tedious job for me and so it will probably be days or weeks before I finally settle on the tips I like the most sound and fit-wise
