Short answer: a tie on sound quality. Both are rated 3.3/5 (#968 and #941 of 1369 in-ear headphones) at nearly the same price ($9.99 vs $9.99), so choose on features and fit.
The case for the CVJ Kira: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: An uneven response, 2.5 dB standard deviation from target.
Why pick the Tangzu Xue Tao: A broadly balanced tuning with a preference score of 65 against the Harman target. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the CVJ Kira or the Tangzu Xue Tao 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.
