Short answer: the Bowers & Wilkins Px7 S3, though neither ranks well in its class. It ranks #453 of 481 over-ear headphones by sound quality, rated 1.7/5, at $429; the Dan Clark Audio Aeon Flow Open ranks #469, rated 1.2/5, and costs $799.99, which makes this an easy call rather than a real tradeoff. 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 Bowers & Wilkins Px7 S3 is the better-sounding pick. 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. 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.
What the Dan Clark Audio Aeon Flow Open does well: It uses 1 x planar magnetic with an easy 13 ohm load. The tradeoff: A tonal tilt of -2.39 makes it sound dark, with bass well ahead of the treble.
Buy the Bowers & Wilkins Px7 S3. It is rated higher for sound quality than the Dan Clark Audio Aeon Flow Open and costs less, so only choose the other one for a particular feature it does better.
