Short answer: a tie on sound quality. Both are rated 3.3/5 (#895 and #924 of 1291 in-ear headphones) at nearly the same price ($9.99 vs $5), so choose on features and fit.

Why pick the FiiO x JadeAudio JH5: A broadly balanced tuning with a preference score of 66 against the Harman target. The tradeoff: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Why pick the Kinera x Elise Audio Dark Phoenix: A broadly balanced tuning with a preference score of 65 against the Harman target. Watch for: An uneven response, 2.3 dB standard deviation from target.
Buy the FiiO x JadeAudio JH5 or the Kinera x Elise Audio Dark Phoenix 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.
