Short answer: the KBEAR Storm. It ranks #978 of 1369 in-ear headphones by sound quality, rated 3.2/5, at $18.04; the KZ ZNA ranks #1049, rated 3.1/5, and costs $22, so there is not much of a tradeoff to weigh.
The case for the KBEAR Storm: Bass is lifted about 5.1 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: An 8.2 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
The case for the KZ ZNA: About 4 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. Watch for: An uneven response, 2.6 dB standard deviation from target.
Buy the KBEAR Storm. It is rated higher for sound quality than the KZ ZNA and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
