This is just demonstrably not true. Bluetooth Hands-Free mangles the sample rate to 16 / 24 kHz. See this video for a collection of pretty much all common devices from "this decade". https://www.youtube.com/watch?v=ifmGS_WWk7o
Especially if you consider the inherent issues with Bluetooth call quality. No matter how good their microphones in them are, they will mangle the audio back to the 90s.
$549 seems entirely detached and I am baffled, even as an ANC enthusiast.
