Short answer: the NF Audio RA05. It ranks #372 of 1291 in-ear headphones by sound quality, rated 4.1/5, at $31.99; the HZSound White Snow ranks #428, rated 4.0/5, and costs $32.99, so there is little reason to consider the other one.
What the NF Audio RA05 does well: The median of 12 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.89 dB spread. The catch: A 6.9 dB peak near 8.6 kHz can make cymbals and sibilance sound sharp.
What the HZSound White Snow does well: 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 NF Audio RA05. It is rated higher for sound quality than the HZSound White Snow 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.
