After some time of use and comparison, these have a strange sound that is tiring, and it is obvious that they fall quite short. On the surface they seem to have a lot of mids, and the best description is in a review I found: "Timbre and tonality is off". I couldn't get them to sound good no matter how much I worked with the equalizer. Sound-wise, it's better to choose something else; the appearance is nice, the packaging is careful, but the sound for music is a bit disappointing and not worth the money (21.7+3.5). Maybe in some applications they sound good, but they are definitely not an all-rounder IEM. I have no opinion on the microphone; the in-line remote is convenient, but also something that may cause a problem in the future.

I would recommend the KZ EDX Lite, which are a SHAME to be sold at such a price (around €5) considering the sound they offer. The ZSN Pro 2 are slightly cleaner than the EDX, have slightly more clarity, lose a tiny bit in bass, and are quite a bit more expensive at around €19.

They fit anatomically perfect, they don't bother during long use, they are quite light, the sound quality is excellent, the bass is rich, the highs are just right, clarity in the sound. In the packaging, there are replacement covers for the headphones. The cables connect to the headphones with connectors, so they can be disconnected and replaced in case of damage either to the cable or the headphones with similar ones or from the same company. The best I've ever had. The price is a bit steep.
