My Grey ZS5 v2 arrived today. I really liked the sound right away. I think it sounds better than the Black ZS6 v2. I believe it was Slater that said the ZS5 v2 is the ZS6 v1? With Sibilance and all? Is my hearing bad? I didn't notice any sibilance yet. As good as people say the ZS10 Pro is... I think I'm done buying KZ's for a while. I just bought the ZS5, ZS6 and ZS7 in the last couple months.
