Short answer: the FiiO FH3. It ranks #913 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $119.99; the Harmonic Empire GuoJia ranks #1000, rated 3.2/5, at $119. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the FiiO FH3: Bass and sub-bass sit within about 1 dB above the Harman target, giving kick drums and bass guitar a full, warm foundation without bloat. The catch: The 3 to 6 kHz presence region sits about 5.7 dB below target, with a dip of 7.4 dB near 6.5 kHz, so vocals and cymbals lose bite and detail.
The case for the Harmonic Empire GuoJia: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The tradeoff: Treble about 6 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the FiiO FH3. It is rated higher for sound quality, and the $0.99 saving on the Harmonic Empire GuoJia is not enough to make up the difference.

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.
