Short answer: the Pula PA02. It ranks #483 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $170.10; the DDHiFi E13P Memory ranks #601, rated 3.8/5, at $169.99. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the Pula PA02: The median of 17 hobbyist measurements gives it a solid Harman preference score of 73 with a 1.93 dB spread, and its mids sit within about 0.8 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.8 dB low with a 7.4 dB dip near 5.8 kHz, so vocals and instruments lose some bite.
The case for the DDHiFi E13P Memory: A semi in-ear 13mm planar earphone with a built-in USB-C DAC and inline remote. Watch for: Treble sits about 4.7 dB below target, a dark, relaxed balance.
Buy the Pula PA02. It is rated higher for sound quality, and the $0.11 you would save on the DDHiFi E13P Memory 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.
