Short answer: the Tin HiFi C2. It ranks #61 of 1291 in-ear headphones by sound quality, rated 4.6/5, at $59.99; the EPZ G20 Pro ranks #198, rated 4.3/5, at $59.99. The price gap is small enough that the sound-quality ranking should decide it.
What the Tin HiFi C2 does well: Across 15 squig.link measurements it reaches a preference score of 81.6 with a 1.42 dB deviation, close to neutral with a slight warm lean. The tradeoff: The 10 to 16 kHz air band runs about 5 dB above target with a 6.2 dB peak near 11.9 kHz, which can make cymbals and hi hats sound a bit sharp to treble sensitive ears.
Why pick the EPZ G20 Pro: The median of 3 hobbyist measurements gives it a very good Harman preference score of 78 with a 1.68 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The tradeoff: A 6.7 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the Tin HiFi C2. It is rated higher for sound quality than the EPZ G20 Pro 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.
