Short answer: the Kefine Klanar. Both are rated 3.6/5 for sound quality (#701 and #722 of 1291 in-ear headphones), and the Kefine Klanar costs $114 against $119.99 for the Hidizs MS3, so with nothing between them on sound quality, price settles it.
What the Hidizs MS3 does well: Eight hobbyist measurements give it a preference score of 69 with a lively V-shaped tuning that suits fans of punchy bass and crisp detail. Watch for: A 10.1 dB peak near 8 kHz and air about 5 dB above target make cymbals, hi hats and sibilance hot, which can tire the ears at higher volume.
What the Kefine Klanar does well: The median of 20 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.14 dB spread. The catch: Presence sits about 3.4 dB low with a 4.7 dB dip near 3.6 kHz, so vocals and instruments lose some bite.
Buy the Kefine Klanar. Both are rated the same for sound quality, and it costs $5.99 less than the Hidizs MS3.

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.
