I've been asked some version of this question at least fifty times. People read that the AirPods Pro 3 and Sony WH-1000XM6 are both 'the best' and get confused, because both can't be best. Here's the actual answer.

The Core Trade-Off

The AirPods Pro 3 are earbuds. The Sony WH-1000XM6 are over-ear headphones. That distinction matters more than almost anything else in audio. Over-ear headphones create a physical seal around your ear that passive isolation before any electronics are involved. Earbuds sit in your ear canal with a much smaller seal. All else being equal — and it's not — over-ear wins on ANC every time, purely due to physics.

ANC Performance

The Sony XM6 wins. The difference is most noticeable on airplanes and in loud cafes — environments with sustained broadband noise. In those situations, the Sony headphones make the world noticeably quieter than the AirPods Pro. In quiet offices, the difference is smaller and some people prefer the AirPods' slightly more natural feel.

Convenience

The AirPods Pro 3 win, and it's not particularly close for iPhone users. The H3 chip's automatic device switching actually works reliably. The case has a satisfying click. The Transparency mode is uncanny. They weigh almost nothing in your ears. You can have a conversation without taking them out. The XM6's companion app is good but requires more deliberate interaction.

The Decision Framework

iPhone user who switches contexts often (office to gym to commute)? AirPods Pro 3. Frequent flyer or open-plan office worker who needs maximum ANC and doesn't mind wearing full headphones? Sony XM6. Android user? Sony, unless you're in the Google/Samsung ecosystem and prefer earbuds.
