Short answer: the BQEYZ Winter. It ranks #926 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $239; the LZ A4 Pro ranks #1002, rated 3.2/5, and costs $246.05, so there is not much of a tradeoff to weigh.
The case for the BQEYZ Winter: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The catch: Presence sits about 4.6 dB low with an 8 dB dip near 10.0 kHz, so vocals and instruments lose some bite.
The case for the LZ A4 Pro: 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: Treble about 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the BQEYZ Winter. It is rated higher for sound quality than the LZ A4 Pro 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.
