Short answer: the Sennheiser MOMENTUM True Wireless 4. It ranks #914 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $250.13; the LZ A4 Pro ranks #1002, rated 3.2/5, at $246.05. Close enough in price that the sound-quality gap is the deciding factor.
What the Sennheiser MOMENTUM True Wireless 4 does well: This true wireless set adds active noise cancelling, Bluetooth 5.4 and a codec list that runs from SBC and AAC up to aptX Lossless and LC3. Watch for: Presence from 3 to 6 kHz is about 6.9 dB under target, with an 8.2 dB dip near 5.7 kHz, so voices and guitars sound recessed.
Why pick 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. Watch for: Treble about 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Sennheiser MOMENTUM True Wireless 4. It is rated higher for sound quality, and saving $4.08 with the LZ A4 Pro does not make up for the sound-quality gap.

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 Sennheiser MOMENTUM True Wireless 4 from boizoff, dhrme, fernandagunsan and silicagel; the LZ A4 Pro from achoreviews, ankramutt and rg, all via squig.link.
