Short answer: the Sony WH-1000XM6, though neither ranks well in its class. It ranks #435 of 481 over-ear headphones by sound quality, rated 2.3/5, at $458. The Sony INZONE H9 II ranks #440, rated 2.1/5, at $348, $110 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 481 over-ear headphones, and the HIFIMAN Ananda Nano, ranked #6 at $319, is a better place to start if sound quality matters.
The case for the Sony WH-1000XM6: Active noise cancelling, up to 30 hours of battery with ANC on (40 with it off) and LDAC, AAC and LC3 support cover most wireless needs, and a cable can be used too. It supports LDAC Bluetooth, which the Sony INZONE H9 II lacks. Watch for: An 11.5 dB dip near 8.1 kHz and treble about 3 dB under target leave cymbals and detail muted, so the sound is dark and heavy rather than balanced, with a preference score of only 43.
The case for the Sony INZONE H9 II: Active noise cancelling, 30 hours of battery (ANC off), a built-in microphone, LC3 support and a wired option make it a flexible gaming headset at 0.6 lbs (260 g). Watch for: A 9.2 dB peak near 7.2 kHz and treble about 5 dB over target make cymbals and sibilance edgy, while a dip near 3.9 kHz pushes voices back, for a preference score of 38.
Buy the Sony WH-1000XM6. It is rated higher for sound quality, and the $110 you would save on the Sony INZONE H9 II does not close the gap.
