Short answer: the Moondrop Space Travel. It ranks #145 of 657 in-ear headphones by sound quality, rated 4.3/5, at $29.99; the Moondrop Space Travel 2 ranks #457, rated 3.6/5, at $29.99. With prices this close, go by the sound-quality ranking rather than the cost.
The Moondrop Space Travel is the better-sounding option. The median of 23 hobbyist measurements gives it a very good Harman preference score of 78 with a 1.56 dB spread, and its mids sit within about 1 dB of target, so vocals and instruments sound natural. The tradeoff: Sub-bass is 2.6 dB short at 30 Hz, so deep bass lacks rumble.
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. The tradeoff: Presence sits about 4.5 dB low with a 10.9 dB dip near 10.9 kHz, so vocals and instruments lose some bite.
