Ambient noise cancellation is not the same thing. Most headphones do it passively by having a closed-back design. It blocks noise from reaching your ears, not the microphone.

Active noise cancellation is not the same thing either. See https://krisp.ai/ for what you really need, and this is not something best done at the physical device level.

Pretty sure they're referring to ambient noise cancellation using the microphones to make it so the background noise doesn't come through your microphone to the other participants while on a call.
