Just a quick post to put what i wrote into pespective : I did want to refrain from posting impressions so early, and now I have to temper some of the things I've said : with a better source than Fuze or SOny s639 HPO (FUze+film caps LOD+E5 or uDAC, and FLAC files), the midbass hump on HJE is not nearly as distracting, bass is tighter and more controlled. Aso it does seem that higher mids and treble on HJE are a tiny bit more refined than on VBs, and that is with foam mods on, without foams the difference is most probably substancially bigger. Sounstage also feel more spacious with those sources but still less so compared to VBs which feel more "out of the head" and 3 dimensional. Dynamics in the mids seem a little better in HJE vs VBs with better sources too. It did sound spectacular with those better sources and FLAC files. But even when HJE very slightly beats VBs in certain areas, VBs beats it in other ones, so they still dont feel better to me.
I wouldnt say that Vbs are "clearer" (only so with lesser sources where the HJEs midbass hump can be distracting on complex musics), as the opposite can be said in other cases, but the VBs are definitely more spacious.
In the end, the differences in build quality and price make them represent the same very good value to my eyes.
JxK : i have the smallest ears a regular man can have and I have no problems fitting the VBs.... They are very comfortable, only the cable is springy, tangly, microphonic and rubbery (in short it SUCKS), HJE have a much better and thicker cable and also dont stick as much out of the ear so they wont bother you like VB can when lying your head sideways on a pillow.
Also, I wouldnt say that HJE are warmer than VBs. When you look at the mids only, VBs can feel like they are warmer than HJE's, because they put just slightly more weight in the lower mids and less in the upper mids.
When looking at the whole sonic range, HJE can feel warmer than VBs because of the accentuated midbass.
"Warmth" seems to be a very subjective and relative piece of audiophile jargon anyway....
Also, I beleive that VBs need even more burn in than HJE before being appreciated, so you have to be warned that you will need patience with these IEMs or you will likely feel a lot of frustration in the beginning.
After more focused and relaxed bedtime listening with a quality source (Fuze+flim caps LOD+E5, which, beleive it or not, is uncomparably better sounding than fuze HPO), I have to give the definite edge in SQ to HJE900..... Without even trying hard or A/Bing with extra focused efforts, HJE sound very noticeably better (with a better source) across the whole spectrum compared to VBs, only getting beaten by VBs in bass extension and soundstage spaciousness.
Actually HJE mids sound a little less laid back in the mix compared to VBs, they're more dynamic, fuller, more detailed with better separation, while also more "liquid" and smoother. HJE bass has also more texture and body, and VBs treble/higher mids are noticeably more sibilant.
Those are still "unmatured" impressions but now VBs edge on soundstage and bass extension doesnt seem enough to compensate for the other areas where it gets handily beaten by HJE. The midbass hump that bothered me on HJE from the fuze HPO is not distracting at all from E5+LOD but much tightened and sometimes a welcome enhancement in the mix.
