Short answer: the EPZ Q5. It ranks #8 of 1291 in-ear headphones by sound quality, rated 4.9/5, at $99; the Truthear Hexa ranks #43, rated 4.7/5, and costs $100.02, so there is little reason to consider the other one.
The case for the EPZ Q5: The median of 28 hobbyist measurements gives it a preference score of 87 with only about 0.85 dB average deviation, so tonal balance is very close to what most listeners prefer. The catch: The 10 to 16 kHz air region sits about 4 dB above target, so bright recordings and hi hats can sound slightly sharp.
Why pick the Truthear Hexa: A preference score of 82 in oratory1990’s measurement and a 1.58 dB deviation put this hybrid of one dynamic driver and three balanced armatures very close to the Harman target. Watch for: The presence region from 3 to 6 kHz sits 2.6 dB under target with a 4 dB dip near 4.5 kHz, which pushes vocals and guitars slightly back.
Buy the EPZ Q5. It is rated higher for sound quality than the Truthear Hexa and costs less, so only choose the other one for a particular feature it 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.
