Short answer: the QKZ Khan. It ranks #194 of 1291 in-ear headphones by sound quality, rated 4.3/5, at $69; the KZ PR3 ranks #298, rated 4.2/5, and costs $71.99, so there is not much of a tradeoff to weigh.
Why pick the QKZ Khan: In squig.link hobbyist measurements the Khan earns a preference score of 77.5 with a smooth 1.67 dB deviation, so its warm, gently V-shaped tuning stays close to what most listeners prefer. The tradeoff: A 5.3 dB peak near 8.7 kHz plus about 3.3 dB of extra air can make cymbals and sibilance sound splashy on bright recordings.
What the KZ PR3 does well: The median of 11 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.93 dB spread. Watch for: A 10.4 dB peak near 10.3 kHz can make cymbals and sibilance sound sharp.
Buy the QKZ Khan. It is rated higher for sound quality than the KZ PR3 and costs less, 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.
