do airbuds noise cancellation work on Iphone 12?

Hey sawhite324,

Welcome to Apple Support Communities. AirPods Pro and AirPods Max includes Active Noise Cancellation. If you have AirPods (1st generation or 2nd generation) Active Noise Cancellation isn't an option.

In order to switch between the different modes which includes Active Noise Cancellation, Transparency mode, and Off, you must be wearing both AirPods. See the steps below on how to change the modes on the AirPods themselves, Control Center, and also the Settings app.

Switch between noise-control modes on your AirPods Max

When you're wearing your AirPods Max, press the noise control button to switch between Active Noise Cancellation and Transparency mode. You can customize which modes to switch between (Active Noise Cancellation, Transparency mode, and Off) in Bluetooth settings on your iPhone, iPad, or Mac.

Switch between noise-control modes on your AirPods Pro

Press and hold the force sensor on the stem of an AirPod until you hear a chime.

When you're wearing both AirPods, press and hold the force sensor on either AirPod to switch between Active Noise Cancellation and Transparency mode. You can customize which modes to switch between (Active Noise Cancellation, Transparency mode, and Off) in Bluetooth settings on your iPhone, iPad, or Mac.

To use Active Noise Cancellation with one AirPod only, use your iPhone or iPad to go to Settings > Accessibility > AirPods, and turn on Noise Cancellation with One AirPod. Then press and hold the force sensor to switch between Active Noise Cancellation, Transparency mode, and Off. 

Switch between noise-control modes on your iPhone or iPad

2. While wearing your AirPods Max or both AirPods, tap the More Info button  next to your AirPods in the list of devices.

3. To switch between noise-control modes, tap Noise Cancellation, Transparency, or Off. To select the noise-control modes that you want to use with the force sensor on your AirPods Pro or the noise control button on your AirPods Max, select two or three modes under Button Cycles Between.
