Intro

With the C10 I was already allowed to review a branch of KZ's subsidiary and was positively surprised. They had a lot to offer and could also satisfy audiophile demands. The C04, on the other hand, has probably the most common hybrid configuration in the budget range (1*DD & 1*BA), but in the tuning it relies on the fun factor, which is reflected in a potent bass and clear V-signature.

Handling

The housing has an independent design and is not copied from KZ this time. It's a bit bulky, because it's very round and big, which doesn't give me any problems in wearing comfort, but could be problematic with smaller ears.

It is made of plastic with a metal plate inside. You could say that the size is a bit exaggerated, because the two drivers are located very far in front and there is just too much space, which wouldn't have been necessary, because it shouldn't play a big role in the sound.

The isolation is very good in both directions. You hear practically nothing. The supplied cable is the same as for the C10 and therefore very solid (4 cores, reinforced earhook, good microphone). In addition, there are the classic KZ-Star-Tips in three sizes and that's it.

Sound

As already mentioned, the C04 should rather find its fans in the bass lover scene.

This one is really potent, clear and with a lot of pressure. This means that you don't get a bulging bass, which makes a lot of noise, but doesn't have any texture, or puts everything else in the shade, but in spite of the big bass part, a bass that goes deep, sometimes becomes a bit muddy, but basically remains very clean and a lot of fun.

Of course, this also influences the mids. These are reduced and already get to feel some of the bass. The warmth makes them more pleasant to hear, but they don't always seem natural, especially with female voices. If the songs aren't very bass intensive, be it acoustics or a lot of singer-songwriter songs, you notice that the mids are very clear and detailed, only the bass doesn't leave enough space for them. Voices are quite clear and have enough body and crisp, but they are also a bit distant compared to the rest.

The trebles are a bit lifted again, but without challenging us. Sibilants are very limited, and they have a great three-dimensionality. This is a tuning like you get it in many other KZ models and typical for the 30095-BA driver of the KZ. This means that you should have a certain affinity for high frequencies, but will be rewarded with airiness, good details and good expansion without being too exhausting.

Outro

While the C10 was still rather balanced in its sound, the C04 focuses on the bass. However, this is very well done and is simply fun. It interprets its role very generously, so that sometimes there is too much bass where there shouldn't be, or not to this level. Electro, hip-hop, but also rock is perfectly covered with the C04. Everything else also works, but you should also like a lot of bass.

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.
