Short answer: the Arisyn BAI YONG. It ranks #1005 of 1369 in-ear headphones by sound quality, rated 3.2/5, at $118; the AFUL Explorer ranks #1023, rated 3.1/5, and costs $119.99, so there is not much of a tradeoff to weigh.
Why pick the Arisyn BAI YONG: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: About 3 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music.
What the AFUL Explorer does well: Bass extends flat to 20 Hz and sits on target across 38 measurements, giving full, even low end without boom. Watch for: The presence region is about 7 dB low with an 8.6 dB dip near 4.1 kHz, the deepest in this group, so vocals sound distant and instruments lose definition.
Buy the Arisyn BAI YONG. It is rated higher for sound quality than the AFUL Explorer and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
