Short answer: the LZ A4 Pro. It ranks #1002 of 1369 in-ear headphones by sound quality, rated 3.2/5, at $246.05. The Sony INZONE Buds ranks #1022, rated 3.1/5, at $238, $8.05 cheaper, not enough of a saving to outweigh the sound-quality gap.
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. The tradeoff: Treble about 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Sony INZONE Buds does well: Active noise cancelling, an IPX4 rating and a USB transceiver connection with up to 11 hours of battery (longer over Bluetooth LE Audio) make it a convenient gaming earbud. The catch: Bluetooth is LE Audio only with the LC3 codec, so many older phones and laptops cannot use it without the dongle.
Buy the LZ A4 Pro. It is rated higher for sound quality, and saving $8.05 with the Sony INZONE Buds 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 LZ A4 Pro from achoreviews, ankramutt and rg; the Sony INZONE Buds from gadgetrytech, melatonin and silicagel, all via squig.link.
