Knowledge Zenith ZS7 Review




The ZS7 has been out for a while now, but I haven’t had a chance to take a listen to it until more recently, thanks to Head-Fier, HiFlight, sending me his review sample, which was provided to him by YooAudio.com.

The ZS7 is the newest version from their line of Campfire clones, starting with the plastic ZS5, the metal ZS6, and now this. I never had the opportunity to listen to the original ZS5, but both the ZS5 v2 and ZS6 had very wide soundstage, impactful bass, but incredibly sharp, harsh, and sibilant treble.

From listening to the ZS7 now, it looks like Knowledge Zenith (KZ) has taken some of the feedback and toned down the ZS7’s treble range and made it a much more enjoyable listen, which is nice to see. The ZS7 still features a big bass boost that can occasionally bleed over and become muddy in busy sections, and struggles a bit with busy sections of songs.




The toned-down bass does also make the soundstage narrower than the ZS6, but that’s an acceptable trade-off since the ZS6 treble was piercing bright and I could not use it for more than just a few minutes.

Anyway, this is going to be a rather short review, but I believe the ZS7 is a decent purchase, but for the same price range of $50 or under, I would strongly recommend the following IEMs:

KZ ZS10 Pro – More balanced sound, slight V-shape, warmer, good extension.

Tin Audio T2 – Neutral Diffuse Field sound. Good mids. Slightly harsh, but cleaner and more detailed than ZS7
