When using the microphone on the first generation AirPods on a Mac, macOS automatically change the codec from AAC to SOC, which reduce the audio quality quite a bit and it is fairly noticeable. As I understand, this is primary due to the bandwidth limit of Bluetooth 4. Does AirPods 2 suffer from the same issue? In other words, when the mic on AirPods is used, does it switch to SOC codec and thus decrease audio quality consequently? AirPods 2 has "Hi Siri" so I suppose the mic is always active. Plus AirPods 2 has bluetooth 5.0. I am wondering if these solve the audio quality when using the mic.
