100% disagree. And I like it in stock, excluding value for $. For me and with my gear, ZS5v1 sounds like open-back IT01, no joke!
Yes it has its tiny faults in SQ but they are almost non-existent when paired with right source gear and amped with lot of "juice"
I`m not going to repeat myself more than saying that ZS5v1 needs certain requirements to be filled to sound great. Lol, it reminds me myself long back when I had Havi B3Pro1 and didn`t understand hype around it (actually I still don`t but I haven`t heard them properly amped though).
From what I`ve read and discussed, to some ZS6 sounds awful while some like it like "TOTL". It`s all very subjective.
You can send me Your ZS5v1 if You hate it!
+1
To me they sound very close to open-back HP.
