It's okay. It's a Chinese dynamic IEM, nothing special.

KZ Zenith delivers a smooth, balanced single-DD tuning with a clearly more capable driver than prior KZ sets. Imaging, detail and treble refinement hint at $100–$200 performance while keeping a $50 tag. Smooth, balanced tuning with unexpectedly strong technicalities for the price, cleaner imaging and microdetail, tasteful treble, and three sub-bass switches for fine adjustment. Fuller mid-bass can thicken on warm sources; slight initial 7–8 kHz glare for some ears and an odd 12 kHz measurement dip; basic stock cable unless the promo upgrade was included.
Youtube Video Summary

KZ Zenith arrives as the flagship single dynamic with a full-alloy shell and a semi-open mesh that vents into the chamber. Four switches provide fine control: 1–3 add roughly +1 dB each to sub-bass, while switch 4 raises overall SPL for low-power sources. The show, however, is the pairing of KZ’s refined 2024 “swoopy” curve with a more capable driver—cleaner note definition, stronger separation, and sharper imaging that blur the line with hybrids. Turned up a bit, staging opens and the presentation stays smooth, without the metallic edge older KZ tunings were known for.

Bass is the full type—real sub-bass and mid-bass carried cleanly into the mids—now with better texture and nuance; the three switches let genre-hoppers nudge it from tidy to fun. Mids benefit from improved attack-to-decay “note completion,” giving vocals and instruments extra focus and microdetail. Treble is about as neutral and transparent as KZ has done—seamless, extended, and non-fatiguing; some may notice a brief 7–8 kHz glare that settles with playtime, and there is a curious 12 kHz dip in measurements that is not a deal-breaker in listening. For the price, Zenith offers a clear window into the technical finesse usually associated with pricier single-DD sets.

It's a middie, but a good option.
