Short answer: the IvipQ IE-01. It ranks #1048 of 1369 in-ear headphones by sound quality, rated 3.1/5, at $35; the Kinera Celest Pandamon 2.0 ranks #1073, rated 3.0/5, and costs $39.99, so there is little reason to consider the other one.
The case for the IvipQ IE-01: About 4 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. The catch: An uneven response, 2.4 dB standard deviation from target.
Why pick the Kinera Celest Pandamon 2.0: A 10mm planar driver is unusual at this low price, and the 9 ohm, 108 dB design plays loud from any phone or laptop. Watch for: Hobbyist measurements put its preference score at 62, with a 10.3 dB dip near 6 kHz and treble about 5 dB short of target, so cymbals, consonants and room ambience sound muted.
Buy the IvipQ IE-01. It is rated higher for sound quality than the Kinera Celest Pandamon 2.0 and costs less, so only choose the other one for a particular feature it does better.

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.
