How recently did you get a v1 Grey from Gearbest? I only ask because I got a v2 a few weeks ago and I've seen a couple of other posts from people who also got v2 when ordering Grey no mic ZS5 from Gearbest.
first one: ordered 7 sep , shipped 10 sep, received 26 sep.
second one: ord 22 sep, shipped 29 sep, received 10 oct.
both gray no mic, both v1, 2nd one defective, got a refund without having to return them.
i've been listening to v1 for some hours, using the new ofc gray cable and stock starline tips and an ultra low output impedance source (no coupling caps).
maybe these zs5 and the cable needed some more burn-in (?), they sound good with same songs, but not so good with others.
after some hours, had to change to zs6 (foams + some minor eq).
zs5 v1 is very finicky about sources, and i could say even about cables, due to its extreme low impedance (i was listening to them using lower resistance cables -the 6 cores with metallic straight jack- days ago, and got the impression of more songs sounding better; maybe my mood was responsible). btw, they need quiet more power than zs6 to reach same volume; i suspect they have lower sensitivity than zs6 (shall measure sensitivity soon), together with higher phase, more current needed.. batteries run out faster.
resuming, i've decided to follow your suggestions, not trying to get a v2, which would be probably worse than zs6 (no "crossover", harsher upper mids and highs, and more finicky overall -output impedance tricks won't be effective to tame the highs-). got a black zs6 instead, using the v1 refund plus the new coupon, to combine with my green ones (liked the look of

if someone wants v2 to get measured, just send me them for a few days..
