Short answer: the OnePlus Buds Pro 3, though neither ranks well in its class. Both are rated 2.8/5 for sound quality (#1053 and #1037 of 1291 in-ear headphones), and the OnePlus Buds Pro 3 costs $167 against $189 for the Kefine Arnar, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
What the Kefine Arnar does well: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. The catch: Presence sits about 7.8 dB low with a 10.8 dB dip near 6.5 kHz, so vocals and instruments lose some bite.
The case for the OnePlus Buds Pro 3: These true wireless earbuds offer active noise cancelling, Bluetooth 5.4 with LHDC 5.0 and AAC support, and an IP55 rating for sweat and dust. The catch: In two hobbyist measurements on squig.link it scores 58.9 for Harman preference, with sub-bass about 5 dB and bass about 4.2 dB above target, enough to make bass heavy and slightly boomy.
Buy the OnePlus Buds Pro 3. Both are rated the same for sound quality, and it costs $22 less than the Kefine Arnar.
