Short answer: the CCA C12. Both are rated 3.8/5 for sound quality (#561 and #614 of 1291 in-ear headphones), and the CCA C12 costs $42.05 against $49.99 for the BQEYZ NI, so with nothing between them on sound quality, price settles it.
What the BQEYZ NI does well: A broadly balanced tuning with a preference score of 71 against the Harman target. Watch for: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the CCA C12: Sub-bass sits within 0.2 dB of target and holds up all the way to 20 Hz across hobbyist measurements on squig.link, and a 3.3 dB lift from 60 to 200 Hz adds warm punch to drums and bass lines. Watch for: The top octave runs 7.5 dB above target with an 8.8 dB peak near 11.9 kHz, which can add sizzle to cymbals and hiss to bright recordings.
Buy the CCA C12. Both are rated the same for sound quality, and it costs $7.94 less than the BQEYZ NI.

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 BQEYZ NI from aftersound, bassaudio, digaoreviews, eplv, jaytiss, soundcheck39 and tonedeafmonk; the CCA C12 from avishai, isaiahse and melatonin, all via squig.link.
