I really took my time hearing the ZS6, mostly because this model was and still is surrounded by audiophile hype just like its predecessor the ZS5. Don’t get me wrong, the first generation ZS5 was amazing for the price, even if a reviewer did made a drama around it.
I was not really impressed when I tried these for the first time because they sounded just like the ZS5 v1.
After playing a lot of my favorite albums, even I must admit the ZS6 sounds better than the ZS5, not by a lot but enough for me to recommend the ZS6 over their predecessor.
The built quality of the shells is pretty amazing for a sub 50€ in-ear, sure it only brings the basics in terms of accessories and the stock cable is rather uncomfortable. The shells are made of metal, not sure if its aluminum but by the wear on the paint after some weeks it sure looks like it.
In terms of comfort, this model feels the same as the ZS5, if you are lucky enough for it to fit nicely on the ear, then great for you, if not be prepared for some adjustments.
The sound of these IEMs doesn’t feel V-shaped, even if the treble can be a tiny bit too much on some songs, they are not bass canons, having a very controlled bass and great mid range.
Probably due to the metal shell design they have a greater soundstage than the ZS5s on some songs. I could ramble on about the sound quality but I’ll just say they sound like little Beyerdynamic DT880s minus some detail and instrument separation. Yea, that good and they are not 200€.
Glad KZ doesn’t yet go the route of a certain audiophile brand and make headphones expensive “Because it sounds good!“, If not these would sell for 300€ or something.
Sure the outside design is borrowed but the sound feels very KZ and I should know because I got most of their “flagships”.
Without much hype these are the best KZ earphones you can buy until the end of 2017, not sure how KZ will improve on this design but my advice would be improving the nozzle end with a little notch so the tips can’t move around so easily and maybe improve the cable which feels cheap and very hard around the ear.
Also, change the design for something truly KZ, I think the brand doesn’t really need to be borrowing designs from other niche brands but that’s me.
The KZ AS10 is a superior in-ear.
