ø8mm + ø6.8mm Dynamic Drivers

4.0/5.0

The premium-looking dual-driver KZ ZS1 are very good earphones to have, especially if you like decent bass. However, you'll most likely have a trouble fitting these into your ears properly.

Pros

  • Pretty clear sound quality overall.
  • The bass goes pretty deep, if you can push the earphones deep enough.
  • A very premium design and pretty solid build quality, even if plastic.

Cons

  • The bass gets slightly distorted at high volume or deep bass drops (like in Dubstep and Trap music).
  • It is very difficult to fit these oddly shaped earphones inside the ears and get a good seal.

Comfort & Fit

No matter how I placed it, no matter which tips I tried, they just don't stay all the way inside. I had to push them in as I listened to them to hear the sound properly.

Lows / Bass

The bass has impact and sound nice, but if your seal is too good it gets muddy. Either way, you need to get a perfect seal to hear the bass properly. When the bass gets deep, it's slightly distorted.

Mids / Vocals

The vocals sound nice, but sometimes overpowered by the bass. They are not so bright either, and have a dark-ish signature to them.

Highs / Treble

The highs are loud but not as bright as I would want them to be, which is probably the result of a bit too warm sound signature.
