Few things are more annoying than when Siri hijacks your AirPods to read aloud a string of text messages while you're listening to a hilarious podcast episode or a great song. The feature allows Siri to announce notifications for iMessage, Reminders, and third-party apps (like Slack, Snapchat, Twitter, WhatsApp, and more) through your AirPods, Beats, and CarPlay. You can also reply to alerts hands-free. In theory, it sounds super useful, but for those who tend to receive a lot of notifications at once (from things like busy group chats or Twitter replies), it can be irritating. While it's not enabled by default, you might've accidentally turned it on via a pop-up while pairing new AirPods (or Beats) or when upgrading to iOS 15.
