Short answer: the TRN Conch. It ranks #96 of 450 in-ear headphones by sound quality, rated 4.4/5, at $29.99; the Moondrop Space Travel ranks #129, rated 4.3/5, at $29.99. The price gap is small enough that the sound-quality ranking should decide it.
What the TRN Conch does well: Fifteen hobbyist measurements on squig.link give the Conch a preference score of 79.0, a strong result for one of the cheapest in-ears around. The catch: Air above 10 kHz sits about 5.8 dB above target with a 6.7 dB peak near 8.1 kHz, so it can sound sharp and sibilant on bright recordings.
Buy the TRN Conch. It is rated higher for sound quality than the Moondrop Space Travel at the same price, which makes it the one to get unless you need something the other one does better.

TRN Conch: $29.99 Amazon eBay
Pros: Fifteen hobbyist measurements on squig.link give the Conch a preference score of 79.0, a strong result for one of the cheapest in-ears around. Bass runs 2.1 dB above target with sub-bass holding on target to 20 Hz, giving music warm weight for V-shaped tastes. Its 114 dB sensitivity and 30 ohm impedance make it simple to drive from a phone.
Cons: Air above 10 kHz sits about 5.8 dB above target with a 6.7 dB peak near 8.1 kHz, so it can sound sharp and sibilant on bright recordings. The presence band 2 dB below target recesses vocals a little, and the KBEAR KB01 earns a higher rating at a similar price.
