Bowers & Wilkins makes speakers and headphones that audiophiles respect. The Px8 is their premium wireless ANC headphone — $449, wrapped in real leather, with B&W's signature sound. Sony's XM6 is cheaper, has better ANC, and beats the Px8 on most features. This is a sound quality versus value argument.
Sony WH-1000XM6
The Sony XM6 is the better value and the better ANC performer; the B&W Px8 is worth the premium only if you prioritize sound quality and premium materials.

Sound Quality: B&W's Advantage
B&W's 40mm carbon cone drivers in the Px8 deliver a more refined, detailed sound than the Sony XM6. The midrange is cleaner, treble more extended and natural, and the stereo imaging more precise.
For classical, jazz, and acoustic music, the Px8 sounds like a higher-tier product. The instruments feel more separated and the soundstage is wider.
Sony's XM6 has a more consumer-friendly V-shaped tune that sounds exciting. The Px8 is more balanced and more accurate. Whether 'accurate' means 'better' depends on what you listen to.
ANC: Sony's Clear Win
Sony's QN3 processor is simply more capable than B&W's ANC implementation. The Px8 has good noise cancellation — adequate for commuting and office use — but it doesn't match the XM6 in mid-frequency attenuation.
B&W designed the Px8 for audio fidelity first. ANC is a feature rather than a core competency. For buyers who need the absolute best noise cancellation, the XM6 is the right choice.
The gap in ANC performance is meaningful. In a loud environment — airplane, train, busy coffee shop — the XM6 provides noticeably more isolation.
Materials and Design
The Px8 uses real leather earpads and headband, anodized aluminum ear cups, and soft-touch finishing. It feels like a premium product in a way that few headphones at any price achieve.
Sony's XM6 is premium plastic — well-made and polished, but clearly not in the same material tier. The Px8 is the more beautiful physical object.
Both fold flat. The Px8 comes with a nicer case. At $449, the premium construction is part of what you're paying for.
The Object vs Tool Question
The Px8 is the rare headphone that rewards close inspection — the leather, the aluminum, the craftsmanship. It's a beautiful object. If you care about the physical quality of the things you own, that beauty has real value.
The XM6 is a tool. An excellent tool with superb noise cancellation and a feature set designed to make your life easier. Sony is very good at making excellent tools.
If you're going to keep these headphones for five years and look at them every day, the Px8's aesthetic quality is worth something. If you just need great ANC headphones, buy the XM6.
