We know that apps are constantly listening for audio beacons ( ultrasonic cross-device tracking) which are used to link different devices to the same person (your phone and your laptop for example) so that they can associate data collected on either device to you and that they use them to log when/where you watch certain content (such as TV ads). Mics are active and listening. I think it would take a large security breech to see what companies are actually doing with what they collect vs what they'll publicly admit they are doing.
