Short answer: the TANGZU YuXuanJi. Both are rated 4.0/5 for sound quality (#393 and #387 of 1291 in-ear headphones), and the TANGZU YuXuanJi costs $52 against $59.99 for the Moondrop Lan 2, so with nothing between them on sound quality, price settles it.
What the Moondrop Lan 2 does well: The median of 6 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.82 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The catch: Its 1.82 dB spread is less even than the best measured sets.
Why pick the TANGZU YuXuanJi: The median of 14 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.14 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.2 dB low with a 5.2 dB dip near 5.3 kHz, so vocals and instruments lose some bite.
Buy the TANGZU YuXuanJi. Both are rated the same for sound quality, and it costs $7.99 less than the Moondrop Lan 2.

Frequency Response Compared
