That's because the ones mentioned are all audiophile headphones focused only on sound quality. There are plenty of headphones, notably the Sony wh1000xm3 for $230, which have bluetooth, noise canceling, and a built-in microphone plus they work with non-ios devices

AirPods, including AirPods Max, support Bluetooth 5.0 and do work with non-Apple devices.

I must've misinterpreted > AirPods Max require Apple devices running iOS 14.3 or later, iPadOS 14.3 or later, macOS Big Sur 11.1 or later, watchOS 7.2 or later, or tvOS 14.3 or later.

It also says: "AirPods Max can be used as Bluetooth headphones with Apple devices using earlier software and with non-Apple devices, but functionality is limited."
