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.

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.
