Short answer: the JBL Tour Pro 2. Both are rated 4.4/5 for sound quality (#145 and #152 of 1291 in-ear headphones), and the JBL Tour Pro 2 costs $169.95 against $175 for the Whizzer Kylin HE10, so with nothing between them on sound quality, price settles it.
What the JBL Tour Pro 2 does well: In hobbyist measurements it tracks the preferred target closely, with a preference score of 79.2 and a very smooth 1.77 dB deviation, so music sounds balanced from bass to treble. The tradeoff: The presence region near 3 to 6 kHz sits about 3 dB low, which slightly softens vocal edge and instrument detail.
The case for 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 JBL Tour Pro 2. Both are rated the same for sound quality, and it costs $5.05 less than the Whizzer Kylin HE10.
