Short answer: the OnePlus Buds Pro 3, though neither ranks well in its class. It ranks #1053 of 1291 in-ear headphones by sound quality, rated 2.8/5, at $167. The 7Hz x Crinacle Diablo ranks #1092, rated 2.6/5, at $159, $8 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
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. Watch for: 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.
The case for the 7Hz x Crinacle Diablo: The single 14.5mm planar driver holds its output down to 20 Hz, sitting about 1 dB above target at 30 Hz, so deep synth lines and kick drums keep their weight. The tradeoff: Across 16 hobbyist measurements it earns a preference score of only 56, with a 7 dB dip near 6.3 kHz and presence about 3 dB shy of target that dull vocals, guitars and cymbal attack.
Buy the OnePlus Buds Pro 3. It is rated higher for sound quality, and saving $8 with the 7Hz x Crinacle Diablo does not make up for the sound-quality gap.
