KZ S3
Ø6.8mm Dynamic Driver

KZ S3 is basically a special edition for the ED3 Youth Version. Both earphones sound the same and the differences are: the package, the housings' color and the cable (including the Y-split and the plug).

Pros
Cons
  • The sound is amazing. Bass is punchy just enough, mids are detailed and the highs are clear and sharp.
  • A robust and nice looking housing and a soft TPE cable.
  • The vocals tend to be slightly shrieky, similar to KZ ED10.

Comfort & Fit

I got a good seal with the pre-applied M-size tips. No problems at all. Still, the generic tips aren't the best at keeping the earphones inside.

Lows / Bass

A great bass quality and depth, just in the right amount, not too much sub-bass. Doesn't overwhelm higher frequencies, but also lacks significant impact.

Mids / Vocals

The vocals are very clear and precise. The great clarity and warm sound signature result in an enjoyable and exciting experience.

Highs / Treble

The highs are bright and crisp, but slightly cold and overemphasized, almost as bright as KZ ED9.
