Hello! Krisp is actually a noise-canceling app that mutes background noise during calls. It is a software application that you can download and install on your computer or mobile device. You can find Krisp on their official website or in the app store of your device. It is not a physical product that is sold by vendors or sellers. If you are looking for a cost-effective solution, you can check out the pricing options on the Krisp website to see if they have any promotions or discounts available. Let me know if you have any other questions about Krisp!
