Mmm, according to the description of the iOS Bose Hear app:
Companion app for Bose® Hearphones™ conversation-enhancing headphones to let you hear the world on your terms. This app is not compatible with Bose QC30 Headphones.
Now I'm curious if the Hearphones have the same ANC capabilities as the QC30s + the extra stuff. That would be interesting.
The Bose QC series don't have that. Nor does the PocketTalker product mentioned in another comment here.
My guess is that the new buds will allow the iPhone as a 3rd microphone, with Apple's "Live Listen"
I missed the reply from Bose: "We apologize for the information you received from our support team as it is not accurate. The Quietcontrol 30 headphones should offer a comparable level of noise cancellation to the previous QC20 model. Although the level of noise cancellation is adjustable on the QC30, they should perform just as well as the QC20."
