Question: Currently building earphones with great active-noise-cancellation is a secret kept within few companies. This means they're expensive($300 headphones from Bose etc). Do neural network make this simpler ? And do you think they can be applied cheaply enough,say for $99 headphones ? I assume this will sell really well, and justify creating a dedicated chip, with time.
