Setting up your AirPods Pro opens up new features for you. You can activate Siri with your AirPods just by saying “ Hey Siri ” out loud, followed by your request. So if you want to know the weather, for example, say “Hey Siri, what's the weather like today?” You can also set Siri to automatically read out any message you receive while your AirPods Pro is on, according to business insider.
1. Open the Settings app on your iPhone.
2. Tap on Notifications.
3. Tap on the Notifications ad.
4. For Siri to read your messages, swipe the Notifications toggle switch to the right to turn it on.
Also, once you've turned it on and your AirPods are connected, Siri will read any text message you receive, along with messages from a variety of third-party chat apps.
When Siri finishes reading the message, your AirPods will listen for a few seconds so you can reply. Just tell Siri you want to reply, then say what you want to reply with.
