Short answer: a tie on sound quality. Both are rated 3.4/5 (#907 and #900 of 1369 in-ear headphones) at nearly the same price ($7.99 vs $6.99), so choose on features and fit.
The case for the BGVP Melody: A broadly balanced tuning with a preference score of 66 against the Harman target. The catch: An uneven response, 2.5 dB standard deviation from target.
What the Tanchjim Ola II does well: A broadly balanced tuning with a preference score of 66 against the Harman target. The tradeoff: An uneven response, 2.6 dB standard deviation from target.

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.
