This is KZ ZSN a hybrid IEM, with 1 balanced armature and 1 dynamic driver. Let’s have a look! KZ ZSN is based on hybrid technology, which means besides the traditional dynamic driver, we get an additional armature driver as well.
- 104dB sensitivity
- 25Ω impedance
- anti-corrosion cable
The main purpose to have a better overall soundstage, especially in the mids and highs. With that vocals and instruments in the high-frequency range get more details.
No cracking, no movement, which is critical. Thumbs up for that.
What is inside the box?
Inside the box, we get the usual KZ stuff. The IEM itself, a braided anti-corrosion cable, some extra ear tips and paperwork. Standard KZ package. Build quality of the IEM is pretty neat. It has a mixture of plastic and metal. The binding of the 2 materials is gapless and well made. No cracking, no movement, which is critical. Thumbs up for that.
The housing is smooth to the touch, well made, got a good comfort and fits well. However the housing is a bit big, so for those with small ears, can be tricky to get a good grip and fit.
The structure of the cable is also good, especially at this price range. The braided cable is massive, also it is anti-corrosion which is also welcome. Both ending of the cable is gold plated, but the 2 pin connector has been changed, so no previous cable will fit, that is kind of a bummer.
Sound quality is acceptable, but I have a feeling that the dynamic driver is a bit more in the focus
Ok, so we covered the build quality and accessories, now let’s talk about the sound quality. First, let’s make some things clear. This is an entry-level model, but with a really good finish. The main character of the sound quality is acceptable, but I have a feeling that the dynamic driver is a bit more in the focus, and the balanced armature is left a little bit behind. This can be clearly seen in the frequency chart. For me who loves OST type of music this is kind of a bummer. Anyway, if you are into bass heavy songs and looking for a good built IEM, this can be a good budget version of it.
