Short answer: the BQEYZ Cloud. It ranks #106 of 1291 in-ear headphones by sound quality, rated 4.5/5, at $172.25; the Whizzer Kylin HE10 ranks #152, rated 4.4/5, and costs $175, which makes this an easy call rather than a real tradeoff.
What the BQEYZ Cloud does well: The median of seven hobbyist measurements on squig.link gives the Cloud a preference score of 79.6 with only 1.46 dB of deviation, so it tracks the Harman target closely from deep bass through the upper mids. Watch for: Air above 10 kHz runs about 4.3 dB hot, with a 5.4 dB peak near 8.1 kHz, so cymbals and sibilant vocals can sound edgy on bright recordings.
Why pick the Whizzer Kylin HE10: A broadly balanced tuning with a preference score of 79 against the Harman target. The catch: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
Buy the BQEYZ Cloud. It is rated higher for sound quality than the Whizzer Kylin HE10 and costs less, 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.
