Short answer: the Sony INZONE H9 II, though neither ranks well in its class. It ranks #440 of 481 over-ear headphones by sound quality, rated 2.1/5, at $348; the Bowers & Wilkins Px7 S3 ranks #453, rated 1.7/5, and costs $429, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 481 over-ear headphones; for better sound, the HIFIMAN Ananda Nano ranks #6 at $319.
The Sony INZONE H9 II is the better-sounding choice. 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.
Why pick the Bowers & Wilkins Px7 S3: It brings active noise cancelling, a claimed 30 hours of battery life and Bluetooth 5.3 with an unusually wide codec list, including aptX Adaptive, aptX HD and aptX Lossless alongside AAC. It supports aptX HD Bluetooth, which the Sony INZONE H9 II lacks. The tradeoff: In two hobbyist measurements on squig.link it scores only 30.7 for Harman preference with a 4.23 dB deviation, one of the least accurate responses in its class.
Buy the Sony INZONE H9 II. It is rated higher for sound quality than the Bowers & Wilkins Px7 S3 and costs less, so only choose the other one for a particular feature it does better.
