The new product price is 40,480 yen. I purchased this product, which has a good reputation for AI noise filtering, to participate in a full on-site project. However, as the project participation was canceled, and it is not necessary for my usual work-from-home setup, I am selling it to someone who needs it. *Please feel free to ask any questions. *Price negotiations are not accepted.
