By the looks of it, it's supposed to be the big brother of the great KZ HDS1. How do they compare? KZ ED3 Youth Version wins in all accounts - sound clarity, bass quality, loudness, and even reacts better to amplified sources.

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.
