For example, if the headphones filter out important sounds around you, such as someone calling your name, siren or car horn, then it is not safe. And now a new Amazon patent can help us avoid these potential dangers.

The system can identify the wearer's name or special phrase through a special algorithm, and can also unblock the warning sounds such as the car whistle when crossing the road.
Although it is not known when Amazon's patent will be applied to actual products, if this function is really used in noise-reducing headphones, it will definitely improve the wearer's safety factor. It is very useful. Patented invention.
