Short answer: the KZ EDCX. It ranks #839 of 1369 in-ear headphones by sound quality, rated 3.5/5, at $10; the Moondrop Droplet ranks #902, rated 3.4/5, at $9.99. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the KZ EDCX: An ultra cheap single dynamic IEM with full sub-bass to 20 Hz and a Harman preference score of 67 across five measurements. The tradeoff: Bass sits about 3.0 dB above target, a bass heavy balance.
The case for the Moondrop Droplet: A broadly balanced tuning with a preference score of 66 against the Harman target. The catch: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the KZ EDCX. It is rated higher for sound quality, and the $0.01 you would save on the Moondrop Droplet does not close the 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.
