Amazon is developing noise-cancelling headphones that will automatically turn off when it senses certain ambient sounds like sirens, car horns, or someone shouting your own name. CNet reports that the company was recently granted a patent for the technology that was filed back in 2014, which means they’ve been working on the invention for a while.

As with most patent creations, there’s a good chance that the headphones won’t make it to the market for a long while, if at all, but it’s comforting to know that all those people who do use noise-cancelling headphones and are completely oblivious to their surroundings may be able to do so (relatively) safely some day in the future, when we’re all listening to Frank Ocean’s new album after it comes out in 2020.
