Intro

Knowledge Zenith delights us in regular decency with new in-ears. The "Terminator", or ZSX, is one of the more interesting models. It is strongly based on the signature of the ZS10 Pro, which in my opinion is one of the best models the company has thrown onto the market lately. The ZSX comes with a BA driver more and also the dynamic driver has been replaced. In addition a new design is introduced, which reminds a bit of the ZSR in terms of fit and ergonomics.

Handling

The ZSX is astonishingly shining again in a new design and is not just a change of the front plates, as with many other models. At first glance, it looks a bit bulkier, but fits perfectly, making the ZSX even more comfortable than the ZS10 Pro. Unfortunately, the front panel doesn't sit 100% on the body, so there's no smooth transition, but that's a haptic flaw and doesn't change the wearing comfort! In other words, the ZSX looks more robust than the ZS10 Pro, but not as valuable.

When it comes to packaging, Knowledge Zenith goes back to the AS10, which gives us a nice black box to unfold, where the earphone is embedded in foam. Nevertheless, we don't get any other accessories than usual. Cable (with or without Mic) and three pairs of silicone tips.

The isolation to the inside is very good, but the external perception for others is only good average.

Sound

On paper, we get almost the same frequency response as the ZS10 Pro. However, this doesn't always mean that the sound is exactly the same. Admittedly, the difference is marginal, but I would still consider the ZSX a small upgrade.

The bass is a bit punchier and more powerful than the ZS10 Pro and therefore a bit more tuned for fun. On the other hand, it doesn't have the same depth, which isn't particularly noticeable due to the prominent, dry and clean midrange bass. As with the ZS10 Pro, we get a bass that you not only hear, but also feel! If the bass of the ZS10 Pro was sometimes a bit too obtrusive, or in rare cases booming, the bass of the ZSX seems even more controlled and more on point, but doesn't quite have the depth. These really aren't big jumps, but a slight fine-tuning.

The mids aren't on the same level as the bass and the treble, but also on a higher level in the price category. Here they don't take anything away from the ZS10 Pro, but they can shine a bit more because of the more controlled bass, because subjectively it doesn't push too much into the mids anymore. Lively and emotional is the stick word here. The upper mids are emphasized as so often, but this doesn't get too intrusive, gives voices a natural tonality and makes guitars crisp. Also voices don't jump directly into the face. It still stands in front of the instruments, but is more on one level.
Everything that makes the ZS10 Pro good here is also done by the ZSX.

In terms of treble, I'd say that the ZS10 Pro has a small advantage over the ZS10 Pro, as does the bass. Knowledge Zenit manages to work out details finely here and scores with a fine resolution and very good expansion. It feels like one of the best I've ever heard from the company in the high frequency range, in relation to the permanent audibility. In rare cases, the ZSX's treble can also be a bit demanding. But if you're already used to this from Knowledge Zenith, you won't have any problems, otherwise the old ZS10 would rather be the choice, with losses in the mid-range.

Where the ZSX doesn't turn out to be a terminator is the stage, but in this segment it is in the upscale range and above all the very good transparency and separation make up for a lot, also in the depth.

Outro

Anyone who already owns the ZS10 Pro can confidently skip the ZSX, because the sound benefit is too low for that. However, if you are looking for an audiophile all-rounder with a fun response, the ZSX is just the thing for you and in my opinion it is the best in-ear from Knowledge Zenith at the moment!

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
