Knowledge Zenith (KZ) impressions thread

  1. Aparker2005
    Loving the ZS10 as I listen more. The not overwhelming highs are a welcome for me. Dave matthews band albums sound amazing on these.

    I asked about my ES4 and they just replied shipping soon.

    So they're basically saying it's an IT01?

    Which model is $5. Those look like the one with dual DD in a side by side configuration and those are like $15 on Ali. To keep on topic somewhat, didn't KZ make a dual DD side by side configuration model? What was it and how did it sound?

    I purchased the ZhiYin Z5000 because of similar reasons. I was curious how much the technology had to do with the good quality sound of the iBasso IT01 and how much tuning and design choices made a difference. The Z5000 are not as good as the IT01 in my opinion but there most certainly are sonic characteristics in common between them. I'd be hesitant to try the QKZ though. I've always thought of them as an OEM for numerous brands that would then take the bodies and general design, type and number of drivers type stuff, and make their own inexpensive IEM that was in no way equal to the product they produced for whatever company it was.

    Are you thinking of the QKZ KD4 (a poorer sounding clone of the UiiSii T8)?

    Otherwise, KZ has never made a 2 x Dynamic where both were identical in size. All of their 2 x Dynamics have had slightly different sized drivers - ZS1, ZS2, ZN1, ZN1 Mini, ZSE, etc

    Close. Not an OEM, but more of a private labeler (for the most part). So if I had excess stock of some IEM (usually a mediocre sounding, low end ChiFi), QKZ would be willing to repackage them for sale as "QKZs". Usually, they don't even bother to change the logos (for example, numerous Plextones) - just the packaging. They have very few (if any) of their own designs.

    I think Pod and B9 also have the DT5's.

    The DT5 was released in 2015.

    I always thought the DT5 was a 1 x co-axial (aka 'dual') dynamic driver, vs 2 x single dynamic drivers (arranged in a push-pull)?

    Co-axial 'dual' drivers like these examples:

    Anyone know for sure?

    KZ's broken english promotional material didn't give much more detail than what I have posted. Yours is an interesting theory, though.

    I have only one pair of DT5's so pulling them apart isn't an option. Perhaps someone who knows a bit of Chinese could lend a hand and do the research.

    In the mean time...

    ...you may be right because the driver housings are on the small side.

    *** EDIT ***

    In the words of the inimitable DocHolliday, "I beg to differ".

    Having given this matter further consideration perhaps the DT5 is equipped with something more akin to Audio Technica's "dual phase push-pull driver system".
    612j3GAjhOL._AC_SL1500_.jpg 81G+XGEIkML._AC_SL1500_.jpg

    Consider the following:
    1) Most Coaxial drivers are fashioned with one larger driver and one smaller driver.

    2) Audio Technica's "dual phase push-pull driver system" are two drivers of the same size.
    KZ's information specifies one size (8.5mm) for both drivers.

    This description is pulled from Audio Technica's website on their CKR SonicPro series IEMs.


    This information was pulled from NewAtlas.com
    3) KZ's origins (engineer that defected from Audio Technica)

    4) Timing of the DT5 release (2015) vs ATH-CKR SonicPro series (mid to late 2014)..
    https://www.audio-technica.com/cms/news/9ed464e7dcb8921c/index.html

    If the DT5 does indeed have two 8.5mm drivers in a "dual phase push-pull driver" configuration then it will likely be the first and only KZ with said technology.

    Whichever turns out to be the case I'm glad I have them.

    ES4 has shipped!

    further listening with the zsr reinforces my initial impressions--they're an "exuberant" listen in the sense of throwing out a big, expansive sound. driver coherence isn't very good--the low end, in particular, tends to sound like a separate subwoofer rather than an integrated part of the whole--but they have a ton of prat and have a surprising amount of microdetail; they're excellent for prog, fusion and other densely recorded tunes and less well suited to acoustic fare. where they conspicuously trail the expensive models they're consciously aping is in accuracy and absence of coloration--these do not purport to reproduce the source precisely, but rather present a juiced-up, adrenalized version of the music. which, depending on my mood, suits me fine.

    I must apologize as the V1 was around $15 at the time I bought them but my favorite AliEx seller let me have mine for $5.77 during the 11/11 sale back in 2015. As Slater says all the early double DD KZ iem's were mixed ie: 6mm & 10mm etc.

    You are correct @DocHoliday , plus it would not have mattered how the DT5 sounded as I was in it for their cool looks and gold banding with the Chinese writing on them:yum:

    Are any of the KZ dual, but different sized :), side by side designs worth having? The collector (or is that hoarder) in me wants a pair but only if it isn't a waste of the $10-$15 I'd guess they'd cost
     
  14. Podster
    For less than $10 I don't think the ZSE is a bad spend with it's 6.8mm and 8mm side by side:wink: My favorite dual KZ is the same drivers as the ZSE and of course that's the ZN1 Mini as they are big, light and powerful. Plus who does not love a big bronze garden hose:hushed: LOL

    I have always liked my ZSE. The design is interesting, they fit me well, and the sound is quite good...nice and airy. These are definitely underrated. I paid $8 that was money very well spent.

    The big difference to their image is smaller than that of KZ's multi-driver hybrids, but it is robust and coherent.

    I'll pull them out for a spin.

    I just remember: I like the ZSE so much that I made my own tongue-in-cheek youtube review - Watched by almost 2000 people. And it got praise from Tyll Hertsens from innerfidelity.com.
