Does the WH-1000XM4 work with calling apps like Skype or FaceTime?
No, the unit supports normal incoming calls only and calling apps for smartphones and computers are not supported. Keep this limitation in mind when planning to use the headset for voice or video calls through third-party applications. (Page 1)
