Short answer: the Kinera Celest Wyvern. It ranks #680 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $29.99; the Moondrop Space Travel 2 ranks #705, rated 3.6/5, at $29.99. With prices this close, go by the sound-quality ranking rather than the cost.
What the Kinera Celest Wyvern does well: A broadly balanced tuning with a preference score of 70 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Moondrop Space Travel 2 does well: The median of 15 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.45 dB spread, and its mids sit within about 1.3 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.5 dB low with a 10.9 dB dip near 10.9 kHz, so vocals and instruments lose some bite.
Buy the Kinera Celest Wyvern. It is rated higher for sound quality than the Moondrop Space Travel 2 at the same price, 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.
