Short answer: the Sennheiser MOMENTUM True Wireless 4. Both are rated 3.3/5 for sound quality (#898 and #919 of 1291 in-ear headphones), and the Sennheiser MOMENTUM True Wireless 4 costs $250.13 against $279 for the ZiiGaat x Fresh Reviews Arete II, and with sound quality even, the cheaper one is the better buy.
The case for the Sennheiser MOMENTUM True Wireless 4: 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.
What the ZiiGaat x Fresh Reviews Arete II does well: Bass through the low mids stays within 1 dB of target and extends flat to 20 Hz, so bass is deep and controlled rather than bloated. The catch: The 3 to 10 kHz range sits about 5 to 6 dB below target with a 9.7 dB dip near 6.5 kHz, so vocals lose clarity, guitars and snares lack bite, and the sound can feel veiled; hobbyist measurements give it a Harman preference score of 65.3.
Buy the Sennheiser MOMENTUM True Wireless 4. Both are rated the same for sound quality, and it costs $28.87 less than the ZiiGaat x Fresh Reviews Arete II.
