Short answer: the Truthear x Crinacle Zero RED. Both are rated 4.9/5 for sound quality (#11 and #19 of 1291 in-ear headphones), and the Truthear x Crinacle Zero RED costs $64.99 against $73.09 for the EPZ Q5 Pro, so with nothing between them on sound quality, price settles it.
The case for the EPZ Q5 Pro: The median of 17 hobbyist measurements gives it an excellent Harman preference score of 85 with a 0.95 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Its 0.95 dB spread is less even than the best measured sets.
The case for the Truthear x Crinacle Zero RED: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. The tradeoff: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed.
Buy the Truthear x Crinacle Zero RED. Both are rated the same for sound quality, and it costs $8.10 less than the EPZ Q5 Pro.

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.
