To each his/her own, I don't know, a lot of people seem to like it a lot. I personally find the resolution to be good, but the bass rolls off (at least in my pair) which makes it sound odd, and there's something in the upper register that sounds artificial to me.
But then again, they might just really really conflict with my preferences, or manage to tick my negative boxes. Or there's a QC problem or whatever. As always, YMMV.

On another note - my Tingo FL800 still isn't sounding as good as my last pair. Channel imbalance/bad driver matching, I don't know, they sound slightly off in placement anyway. From memory, the bass doesn't hit as deep as my old pair, but that's more uncertain since I can't do a direct comparison. However - that soundstage, that transparency! Holy cow.
I have other IEMs that do a lot of things better than at least this pair, but that soundstage is just captivating, I have nothing else that comes close, at least not IEM..
At the moment I feel myself reaching for my Sendiy M2 (with ED9 brass nozzles with plugged in holes + "Sennheiser style" dual flange tips) more often, though. Still, that soundstage...
