Short answer: a tie on sound quality. Both are rated 3.1/5 (#1036 and #1038 of 1369 in-ear headphones) at nearly the same price ($2 vs $1.90), so choose on features and fit.
The case for the CCZ BC02: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: An uneven response, 2.7 dB standard deviation from target.
Why pick the Twistura D-MINOR: 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: An uneven response, 2.8 dB standard deviation from target.
Buy the CCZ BC02 or the Twistura D-MINOR 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.
