Short answer: a tie on sound quality. Both are rated 3.6/5 (#703 and #728 of 1291 in-ear headphones) at nearly the same price ($129.99 vs $129.99), so choose on features and fit.
Why pick the Kinera Celest Phoenixcall: The median of 16 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.38 dB spread. The catch: A 6.1 dB peak near 1.5 kHz can make cymbals and sibilance sound sharp.
Why pick the TRN Jaws: An eight driver hybrid with three dynamic drivers, four balanced armatures and a planar. The tradeoff: A 2.37 dB spread from the target shows peaks and dips that better tuned sets avoid.
Buy the Kinera Celest Phoenixcall or the TRN Jaws on features: they are rated the same for sound quality at close to the same price.

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.
