You’ve always been able to use your iPhone as a recording device to log down voice memos with unwitting subjects — the legality of that recording varies from territory to territory, but for legal codes that permit one-party consent, it’s a thing.

But an iOS 12 feature called “Live Listen,” which works with AirPods, has been brought to the public’s attention.

If u have AirPods ?, u can press “Live Listen” to “On” and leave your phone in the room with someone and u can hear what they saying, thank me later? pic.twitter.com/fC6KYmqpB4

While you may not necessarily be recording communications, this feature may still subject you to any wiretapping laws in your jurisdiction. It may be best practice to notify those around you that you will be using Live Listen before using it.
