Short answer: the Moondrop Pudding. Both are rated 4.1/5 for sound quality (#315 and #327 of 1291 in-ear headphones), and the Moondrop Pudding costs $49.99 against $54.99 for the KBEAR KB03, with sound quality a draw, the lower price decides it.
What the KBEAR KB03 does well: The median of 6 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.77 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The tradeoff: A 4.6 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
What the Moondrop Pudding does well: The median of 16 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.50 dB spread. Watch for: Presence sits about 3.8 dB low with a 5.5 dB dip near 2.3 kHz, so vocals and instruments lose some bite.
Buy the Moondrop Pudding. Both are rated the same for sound quality, and it costs $5 less than the KBEAR KB03.

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.
