Short answer: the BLON Shu. It ranks #899 of 1369 in-ear headphones by sound quality, rated 3.4/5, at $2.49; the Blon A6 ranks #1039, rated 3.1/5, and costs $2.99, so there is little reason to consider the other one.
What the BLON Shu does well: A broadly balanced tuning with a preference score of 66 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the Blon A6: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The tradeoff: About 4 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music.
Buy the BLON Shu. It is rated higher for sound quality than the Blon A6 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.
