Short answer: the KZ ZSX. It ranks #917 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $49.99; the Meaoes Eagle ranks #996, rated 3.2/5, at $49.90. Close enough in price that the sound-quality gap is the deciding factor.
What the KZ ZSX does well: A one dynamic plus five balanced armature hybrid at a budget price, with sub-bass within 1 dB of target and midbass about 2.4 dB above it, so electronic and hip hop tracks get punchy, full lows. Watch for: Across eight hobbyist measurements on squig.link a 10 dB peak near 11.9 kHz stands out, which can make cymbals and hi hats sound splashy and tizzy, while a 6.8 dB dip near 6.5 kHz leaves the treble uneven.
The case for the Meaoes Eagle: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: Treble about 4 dB above target from 3 to 10 kHz, which can sound sharp or tiring at higher volume.
Buy the KZ ZSX. It is rated higher for sound quality, and saving $0.09 with the Meaoes Eagle does not make up for the sound-quality gap.

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.
