Will my experience be compromised using AirPods Pro with Bluetooth 4 only hardware? I have a MacBook Air 2014 with Bluetooth 4.0 and I’m considering to buy AirPods Pro. I assume that it makes sense to promote an accessory with the lowest standard they're compatible with, and AirPods Pro are promoted with Bluetooth 5.I can’t find answers to things like does Stereo sound or Spatial Audio require 5.0. The Wikipedia article  only mentions iOS devices.
Will a macOS 4.0 device compromise AirPods features in any direct way?
Yes, AirPods Pro will work with a MacBook Air 2014 and provide stereo sound. You will not, however, enjoy Spatial Audio, that is reserved for iOS devices only. See this support document for specific requirements regarding spatial audio.
