Knowledge Zenith (KZ) impressions thread

    2019 was really different than 2018.

    In 2018, they released earphones every 3-4 weeks.

    In 2019, there were (I think) 4 total?

    I’m glad they slowed down though. Look at how much better the 2019 releases were - ZS10 Pro, ZSX, C12, etc.

    I’d much rather have quality than quantity.

    We should be getting the C18 at some point soon (or whatever they’re going to call it). I am honestly surprised they didn’t have it out for 11.11. They teased it over a year ago (maybe even 18 months ago).

    Myself, I would love to see a follow up to the ZS7. The ZS8 ohhh yeaaahhh (said in a Macho Man Randy Savage voice lol)

    Man, I was just enjoying the original ZS1 v1 (brass ring) last night. How far things have come!! It still holds up though, like good vinyl on a vintage hifi setup. I’ve been wanting to do an mmcx conversion on it, but I’m very hesitant. It’s too rare and too good to risk screwing up.

    Listening largely to C16 an C12, I sadly miss C18 all this time :frowning2:
    Ordered NX7 pro out of the sadness, no high expectations though.

    I got a friend who has a multi-meter to attach MMCX connectors to the KZ Type-C DAC cable (Para-A). The cable was cut to attach the MMCX connectors btw. He faced some problems like : the inner (metal) core of the cable seemed to be covered with some kind of nylon (?) sheath so it was difficult to solder (he then actually burned off the sheath). Also the live cable seemed to be different from the ground : live was golden/brass while the ground was silver.

    I was wondering if you could please write a small guide / provide tips for such projects. Especially for soldering such tiny components.


    I used the original DT6 MMCX cable (I have a better MMCX cable). If I like the DT6 + KZ Type-C combo I'll buy MMCX connectors and attach them to the Type-C cable.

    I have KZ ES4, ZSN and ZSN pro

    KZ ES4 reacts to Harman eq curve (auto-eq github) the best.

    And KZ ES4 sounds technically better than ZSN and ZSN pro(yes...the ZSN pro is the worst sounding to my ear)

    ES4 doesnt hiss, keeps a stable image and is not over the top loud.

    ZSN bass decay collapses the whole stage for weird letterbox type of sound stage

    And this becomes too extreme on ZSN pro.

    Since ZSN and ES4 measured the same...I tried the EQ(Harman curve)
    And ZSN sounded nice...but bass decays a lot more and the decay feels artificial

    Made the ZSN pro curve myself by taking a comparison between ZS10pro and ZSN pro and then editing the ZS10pro Harman target file to ZSN pro

    ZSN pro improved a lot...

    But that bad hissing is still there... And I have tried 4 pairs of ZSN pro (friends got it) to confirm the hiss...and the hiss exist.

    Ok review

    ZSN pro volume down > ZSN > ES4

    After EQ

    ES4>>>>> ZSN > ZSN pro

    Happily reporting:
    KZ AS12 - the insight of Master @Slater for a possibility in removing treble filters.

    Worked really well for AS12 for me!
    Previously I did it for CCA C16, which resulted in definite positive changes - bringing more life to the treble.

    For AS12 it was more startling.
    I almost put AS12 aside, for me the timbre felt quite a bit distorted. Muffled treble, some unnaturalness, especially in orchestral brass.

    With the filters removed, AS12 are so much more enjoyable for me! So much more natural! The treble got hotter, but I feel it is much closer approximation for me how I hear the live music that can often get a bit harsh, but more lively.

    AS12 saved for me, thank you!

    Now, I am looking forward to compare AS12, C12 and C16 with NX7 pro for the king of budget ChiFi to my ears :)

    Were green ZS6 discontinued 2017-2018? Lurking around, it seems like there's a ZS6v2 now. If a green is for sale, is it a v1? Need to re-up on my favorite IEM

    the black line doesnt follow the proper response...
    because the dip in 3kHz cannot be compensated properly, so i modified the response

    i have added the eq file

    I bought a green ZS6 a few months back and it sounded like the treble was toned way down, I don't think all greens are v1 or if there are any v1s for sale now unfortunately
  10. Slater
    All the colors have been toned down.

    Unfortunately, that’s what all of the complaining got us. KZ quietly retuned the ZS6, and they sucked all of the life out of it in the process. It’s boring and generic sounding, with very little treble presence. The result sounds dark and distant, but I understand why they did it.

    I much prefer the ZS6 v1, just like I prefer the ZS5 v1 (which everyone also complained about at the time, but eventually came to regret it after KZ retuned it).

    Did you investigate whether dampening filters were used or BAs were retuned?
  12. Slater
    No filters that I could see.

    My guess is they used different BA drivers in place of the 30095. And possibly they tweaked the crossover to dampen the upper treble frequencies.

    What's up with KZ? They haven't released anything new in ages(for them). :)

    they've released the KZ ZSN Pro "Commemorative Edition" or what its name is with the nice looking blue backplate

    but that's all "new" going on for them it seems.

    Wondering what they're brooding over ...

    RIP to the ZS6v1 then :/ The 2-pin connector on my left IEM is loose, so I was hoping to get a back up. So difficult to find them after-market, tho.

    Time to look into a new IEM 8)
