Intro

Some time ago KZ caused some confusion with the ED16, because it was marketed as ED16, but ZS7 was written big on the In-Ears. Now KZ has solved the mystery by releasing the right ZS7. This has 5 drivers (1*DD & 4*BA) which are the dynamic drivers of the ZS10 and the BA drivers of the AS10. This is KZ's reaction to the split criticism that the bass of the AS10 is too analytical, dry and does not offer enough sub-bass. So, it's very obvious to take the old dynamic driver and combine it with the rest of the otherwise highly praised AS10. They use the proven design of the ZS6. More internal theft is not possible. Whether the fusion of the individual elements to a new flagship will be enough we will now have a look.

Handling

The design of the Campfire Andromeda has often been copied by other companies and has often been very popular. Even if it is not the own design, the ZS6 is one of the most beautiful designs and with the most valuable haptics of the company. Since the ZS5 the design is already available in the series and so it seems only consistent to continue this.
The openings on the back have become a little more sloping compared to the ZS6. Otherwise, we are holding the same in-ear in our hands on the outside. That means we get a full metal body despite the somewhat bulky construction a comfortable fit, as well as detachable cables.
The latter is no longer a big criterion, but KZ has to explain to me why, after the introduction of the new cables, they fall back on this damn cable with the metal reinforcement. That's outdated and makes the insertion fiddly. For that you get the new packaging, which doesn't have more content to offer like all other models, but it's a bit nicer.

The isolation to the outside is not the best due to the open construction (air shafts) but has positive sound characteristics. The outside world is very well shielded as soon as the music starts.

Sound

The ZS7 is really a positive surprise in terms of sound. KZ didn't have to go to much trouble either, as they simply combined three existing, very good in-ears. However, they didn't put anything together, but combined the positive features of the AS10 and ZS10, as well as the outer features of the ZS6.

The bass doesn't necessarily have more impact than the AS10, as it was already more than decent in terms of midrange, but it plays deeper and is much more dynamic. The correct increase is at just under 20 Hz, but it only develops the right amount of pressure at 30 Hz. But this should be enough for many genres. With Joachim Pastor's "Millenium" it rattles more than sufficiently in the positive sense, because the bass stays under control. At the lowest notes of Trettmann's "Billy Holiday" it decreases a bit, but they are still clearly audible.
It gives the ZS7 a nice warmth and stays away from the midrange as far as possible.

The mids are basically the same as those of the AS10. I would call them a bit more reserved in the lower frequencies, because the bass doesn't push too much upwards, but the mids also lose some body. Instrumental pieces by Hans Zimmer have a wonderful separation and above all a stage. For me, this is also an improvement compared to the AS10, which is probably due to the large openings on the back, which gives the sound some room to breathe.
The higher mids unfortunately share the small deficiency of the AS10. They are a bit too prominent at higher volume, which becomes a bit unpleasant in the long run. This is noticeable, for example, in the Xylophone of the movie theme "You're So Cool".
Voice reproduction has also been successful, both for women and men. They lie well in the room and fit in well with the overall sound.

The treble has everything you could wish for. They are clear, detailed with good extension. However, as is usual with the AS10, they do not tend to any strenuous peaks. Fine micro details can be noticed in the songs when they are hidden inside. The sibilants are not emphasized, which I prefer to check with Iggy Azalea's "Impossible Is Nothing", because they are strongly pronounced in the song. Also "Fire" by Ayo is bearable, but that's to be rated as good, because I found only a few in-ears so far who can do this, like the Tin AUDIO T2. The highs aren't particularly wide, or brimming with brilliance, but they are simply pleasant and offer a lot at the same time.

Outro

For about 40€ you get everything you can wish for. Dynamic, detailed sound, deep, clean bass and clear, pleasant treble measured against the KZ universe. In addition, a wide stage and great 3D-location. Although they are a bit warm, which might deter purists, they climb to the top of the KZ rankings for me and are also cheaper than the pure BA models (BA10 & AS10). Knowledge Zenith can be mainstream!

With the code: CHI-FIEAR you can get the ZS7 on Ali-Express for 33€. To do this, go to other payment options when paying and then cancel the payment. The seller then adjusts the price.

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.
