I should not give a final verdict yet. I feel the signature is still adjusting. This is a weird feeling for me. I hardly ever notice a burn in factor on other gear. But in this case it is significant.
Only from yesterday I sense a big improvement in the micro detail, and right now I get a feeling that I listen to the music in a cathedral with thick stone walls.
With depth I mean 3D sound stage. I'm still using VE thin foams and running them on high gain at 10 o'clock on the FiiO X3ii/K5 combo from my HTPC. I also used them on the XDuoo X3 at -27 level and that was pleasant as well.
The bass is not overly impactful, but quite precise and distinct. I guess I will get a much more bassy signature if I change to donuts. I will try with the included full foams again when I decide the burn in is done. I did not like the included foams out of the box, but perhaps they will best in the end...
In some weird way I get a feeling the percussion vibrate inside of the buds, not in a disturbing way. Rather that percussion instruments sound very much engaging and present without stealing the show.
The cable quality is not top notch, but not bad. Somewhere in the region of Boarseman MX98s and MusicMaker Ting. Only problem is the slight microphonics.
This Blox experience is the most exiting path I've taken since I started buying buds.
