How Noise-Cancelling Headphones Work
The gist
Noise-cancelling headphones use tiny microphones to pick up outside sounds and then create opposite sound waves to cancel them out, making the noise less noticeable.
Explain like I'm 5
It's like if someone is making a loud noise and you shout the exact opposite sound to cancel it so you can hear your music better, just like magic earplugs.

This technology helps people enjoy music or focus in noisy places by reducing distractions, improving comfort and audio experience in everyday life.
