i don't c any noise cancellation icon using iphone 11pro max latest update

Hello cooooodes,

Thanks for choosing the Apple Support Communities. If we understand correctly, you are unable to use Active Noise Cancellation on your Beats Studio Buds. We can understand why you'd reach out for a solution.

Here is how to find those settings according to Beats Studio Buds and Beats Fit Pro Active Noise Cancellation and Transparency mode - Apple Support

"Switch modes on your iOS or iPadOS device

1. Open Control Center on your iOS or iPadOS device.
2. While wearing your Beats Studio Buds or Beats Fit Pro, touch and hold the volume slider until you see the additional controls.
3. Tap the Noise Control button  in the lower-left corner.
4. Tap Noise Cancellation, Transparency, or Off.

You can also switch between listening modes in Settings:

1. On your iOS or iPadOS device, go to Settings > Bluetooth. 
2. Tap the More Info button  next to your Beats Studio Buds or Beats Fit Pro in the list of devices.
3. Under Noise Control, tap Noise Cancellation, Transparency, or Off."

Cheers!
