Short answer: the Kinera Celest Plutus Beast. It ranks #648 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $89; the Tangzu x Divinus Fudu ranks #767, rated 3.6/5, at $89. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the Kinera Celest Plutus Beast: The median of 11 hobbyist measurements gives it a solid Harman preference score of 70 with a 2.31 dB spread. The catch: A 4.6 dB peak near 2.0 kHz can make cymbals and sibilance sound sharp.
What the Tangzu x Divinus Fudu does well: A hybrid collaboration between Tangzu and Divinus with one dynamic driver and two balanced armatures. The catch: Treble sits about 3.5 dB below target, a dark, relaxed balance.
Buy the Kinera Celest Plutus Beast. It is rated higher for sound quality than the Tangzu x Divinus Fudu at the same price, which makes it the one to get unless you need something the other one does better.

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.
