Short answer: the ARTTI T10 Pro. Both are rated 3.3/5 for sound quality (#907 and #897 of 1291 in-ear headphones), and the ARTTI T10 Pro costs $109 against $119.99 for the FiiO FH3, with sound quality a draw, the lower price decides it.
What the ARTTI T10 Pro does well: Bass is lifted about 3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 4 dB low with a 4.9 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
The case for 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.
Buy the ARTTI T10 Pro. Both are rated the same for sound quality, and it costs $10.99 less than the FiiO FH3.

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.
