Short answer: the KZ Axas. It ranks #329 of 1291 in-ear headphones by sound quality, rated 4.1/5, at $32.99; the HZSound White Snow ranks #428, rated 4.0/5, at $32.99. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the KZ Axas: The median of 3 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.66 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. Watch for: An 8.2 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Why pick the HZSound White Snow: An inexpensive single dynamic IEM that measures well (score 74 across seven measurements) and comes with tuning filters. The catch: The current Amazon listing pairs it with a USB-C cable, so check for a 3.5mm cable if your source needs one.
Buy the KZ Axas. It is rated higher for sound quality than the HZSound White Snow at the same price, which makes it the one to get unless you need something the other one 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.
