ANC

This video explains ams’ highly optimized ANC technology, a noise cancellation solution for headphones and headsets. ANC reduces unwanted noise from the ambiance while improving the listening experience of mobile communications and multimedia applications. Beside all functional qualities, ams’ ANC offers much more: a monolithic design that has the smallest footprint on the market. ANC solutions are highly cost effective and consume the lowest power of any other equivalent solution. In short, ANC helps to significantly reduce noise induced stress and enhance the listening experience in everyday life.
