Short answer: the Moondrop Chu 2 DSP. It ranks #54 of 450 in-ear headphones by sound quality, rated 4.6/5, at $27.99; the KBEAR KB01 ranks #78, rated 4.5/5, and costs $29.99, so there is little reason to consider the other one.
Why pick the Moondrop Chu 2 DSP: In the median of 6 squig.link measurements it scores 80.6 for preference with a smooth 1.27 dB deviation, excellent for an entry level earphone. The tradeoff: Presence from 3 to 6 kHz is about 3.1 dB under target with a 4.7 dB dip near 5.8 kHz, followed by a 4.2 dB peak near 8.1 kHz, so vocals lose some edge while sibilants can stand out.
What the KBEAR KB01 does well: Nine hobbyist measurements on squig.link put its preference score at 79.6 with a smooth 1.36 dB deviation from target. Watch for: A 4.9 dB dip near 6.2 kHz softens attack on snares and guitars, then a 4.2 dB peak near 11.9 kHz can make some cymbals sound slightly splashy.
Buy the Moondrop Chu 2 DSP. It is rated higher for sound quality than the KBEAR KB01 and costs less, which makes it the one to get unless you need something the other one does better.

KBEAR KB01: $29.99 Amazon eBay
Pros: Nine hobbyist measurements on squig.link put its preference score at 79.6 with a smooth 1.36 dB deviation from target. Sub-bass lands right on target and the 60 to 200 Hz bass is lifted about 1.3 dB, giving a warm, full sound that suits bass lovers. It costs less than the Moondrop Lan, which shares its rating.
Cons: A 4.9 dB dip near 6.2 kHz softens attack on snares and guitars, then a 4.2 dB peak near 11.9 kHz can make some cymbals sound slightly splashy. The KZ Merga has the same rating for even less money.
