AirPods sampleRate with audio session playAndRecord too low?

Hi,

I am testing our app, that is processing audio using low level Core Audio functions (Audio Unit - RemoteIO and Audio Graph).

When observing audio route changes, I realised, that when AirPods are connected, the audioSession.sampleRate is 16000 only. When normal wired pods are connected or when buildin speaker is used, the standard 48000 is used.

The quality of sounds seems to be too low - it is really so low sample rate, when AirPods are used in playAndRecord?
