Intro

Almost 8 months after the release of the ZSN, KZ delights us with a Pro version of the In-Ears.
What has changed? The metal front panel was changed and the dynamic driver was replaced with a double magnet driver to get more precision and depth. What this "upgrade" brings is now to be clarified.

Handling

The case is basically the same as the ZSN, but the metal front panel has been reworked, which means that the design elements (stripes) are no longer engraved, but turned over to the outside. In addition, the metal has become darker and instead of 3 screws, one is enough for the Pro version. Personally, I find the new design more appealing.

As with the ZSN, KZ relies on a PVC ear reinforcement for the cable, which makes it much more comfortable to use than the fiddly metal-reinforced cables, which now seem to be a thing of the past, as for example the new ZS10 Pro relies on the new cable, as well as many models from the subsidiary CCA.

Otherwise, the package content is similar to that of the ZSN, which means 3 pairs of silicone tips, as well as the mentioned cable. Thus, in KZ manner, it is very spartan. No matter, as long as the sound suits!

The isolation is inwards, as well as outwards, as with almost all KZ models, in a good range and can be still improved with Foamtips. As with the ZSN, the wearing comfort is excellent!

Sound

While the ZSN was more neutral, the ZSN Pro sounds more fun to tune.

This is largely due to the bass, which has more punch due to the double magnet and also adds a little extra in the sub range. For those who found the bass of the ZSN too much, the Pro will certainly not be any happier. All others get a crisp bass that rarely tends to exaggerate and, compared to the ZSN, has a stronger influence on the mids. This is where the opinions will certainly differ and the personal taste will remain.
Since I like to have a little more bass, I appreciate the tight and direct nature of the ZSN Pro in the bass range. I also take the disadvantages as a compromise in the price range.

The mids are, as with the ZSN, quite clear and detailed, but they are more prominent, especially in the upper mids. This makes the ZSN Pro more midrange-heavy and more "In Your Face". The bass pushes into the mids from below, which makes them warmer than the ZSN and makes them slightly less natural. Again, I have to admit that I prefer more direct mids than when they're too pale or thin. Here, too, the overall signature is always important to me, but in a V-signature, I find preceding mids more pleasant than when they are drowned or appear too dull. This was not the case with the ZSN, but the mids were smoother. Again, this is the notorious question of taste.

Knowledge Zenith has one trademark and that is certainly the mostly bright highs, which tend to emphasize sibilants and often show the odd unpleasant peak. For people who are sensitive to highs, this is always a challenge, especially when it comes to the long-term audibility of the models. Even the Pro version is not immune to this! Just as typical for concentration camps is the level of detail and the spatiality, as well as the separation, which is usually well above average in the price category. Here the ZSN Pro also plays its trump cards compared to its predecessor, since the individual points were once again particularly examined under the magnifying glass and here a further step forward was made, also concerning the resolution.

Outro

I find the term "Pro" somewhat misleading here, as I personally would expect a finer tuning and more neutrality under it. But that is not the case with the ZSN Pro. It turns out to be a very fun IEM, but you don't have to sacrifice details and space. In addition, we get the slightly better highs, which don't seem quite as sharp as on the ZSN, and a punchier bass with more depth. Basically, the ZSN Pro is an upgrade for me because I like the signature more and also get more bass impact. For purists who have become friends with the ZSN, the Pro version is certainly not a worthwhile investment. But I'll stick with it: personal preferences clearly decide here.
The Pro version is not a 180° turned in-ear, as is often the case with "PRO" versions of the company, but still a very decent IEM with fun factor.

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.
