This is using a pair of any old commercial microphones that you can attach to your headphones, without looking like you're from the CIA and pointing a spy microphone at people
With a parabolic microphone you have to keep it aimed at the person you want to listen to. If they or you are moving (other than directly toward or away from each other) you will need to keep moving the microphone.
With this you look at someone, signal that you want to keep listening to them, and the AI learns their voice. It then lets that voice through the noise cancelling system even as you or they move around the room or you look elsewhere.
