Short answer: the ND Nice. It ranks #616 of 1291 in-ear headphones by sound quality, rated 3.8/5, at $15.99; the KZ EDC Pro ranks #637, rated 3.7/5, at $15.99. The price gap is small enough that the sound-quality ranking should decide it.
The case for the ND Nice: A broadly balanced tuning with a preference score of 71 against the Harman target. The catch: An uneven response, 2.4 dB standard deviation from target.
What the KZ EDC Pro does well: Exceptional value: the median of 22 measurements scores 70 on the Harman preference scale with a 2.0 dB spread, unusually even for a budget IEM. The catch: The bass lift makes it fun rather than neutral, and a 5.6 dB peak near 12 kHz can add sparkle that edges toward sharp on bright recordings.
Buy the ND Nice. It is rated higher for sound quality than the KZ EDC Pro at the same price, so only choose the other one for a particular feature it does better.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
