Short answer: a tie on sound quality. Both are rated 3.1/5 (#1039 and #1036 of 1369 in-ear headphones) at nearly the same price ($2.99 vs $2), so choose on features and fit.
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.
What the CCZ BC02 does well: 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, 2.7 dB standard deviation from target.
Buy the Blon A6 or the CCZ BC02 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.
Measurement data: the Blon A6 from audioamigo, soundcheck39 and tonedeafmonk; the CCZ BC02 from eplv, pw and tdl, all via squig.link.
