How about ZS5v1 soundstage&airiness compared to ES4 ? What are You using as source gear (is ZS5v1 amped enough + are You using low output impedance source)?The ES4 is a really fantastic earphone, from what I'm hearing so far. Like, really really good. And I didn't really like much about the ZSR, and found treble overbearing on the ZS6. I do love the ZS5 (v1) and ZS3 however. I'm really impressed and it makes me want to give the ZSA and ZS10 a shot for sure.
Please more impressions ZS5v1 vs. ES4 !
