Short answer: the Hidizs MK12 Turris. It ranks #894 of 1291 in-ear headphones by sound quality, rated 3.3/5, at $79. The KZ AS16 Pro ranks #968, rated 3.1/5, at $73, $6 cheaper, which does not close the gap in sound quality.
What the Hidizs MK12 Turris does well: A broadly balanced tuning with a preference score of 66 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the KZ AS16 Pro: Bass is lifted about 2.2 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The catch: Presence sits about 3.8 dB low with an 8.6 dB dip near 5.9 kHz, so vocals and instruments lose some bite.
Buy the Hidizs MK12 Turris. It is rated higher for sound quality, and the $6 you would save on the KZ AS16 Pro does not close the gap.

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.
