AirPods Pro have three noise control modes: Active Noise Cancellation, Transparency mode, and Off. By default, when you press and hold the force sensor on the stem of your left or right AirPod, your AirPods Pro switch between Active Noise Cancellation and Transparency mode.* You can change which noise control modes the press-and-hold action uses:

Go to the settings screen for your AirPods Pro. Under Press and Hold AirPods, tap Left or Right, then make sure that Noise Control is selected. Select the two or three noise control modes that you want to use with press and hold. If both AirPods are set to change noise control modes, a change to the press-and-hold action settings on one AirPod applies to both.

You can also set the press-and-hold action to allow you to use Siri. In the AirPods Pro settings screen, tap Left or Right, then select Siri. You can have one AirPod set for Siri and the other set to change noise control modes.

* You can switch among all three noise control modes in Control Center or Settings.
