I truly don’t understand the mechanics of this.

Active noise cancellation means that they use a microphone to monitor the ambient noise and actually play sound into your ears at the exact frequency to negate the noise around you.

When it’s turned off, it’s just not doing any of that.

Earbuds have tiny microphones in them that pick up the sounds around you. When you turn on noise cancelling, the earbuds use these microphones to listen to the sounds around you. They then create an “anti-noise” sound wave that is the exact opposite of the noise around you. This cancels out the noise, making it harder for you to hear it. When you turn off noise cancelling, the earbuds stop creating the anti-noise sound wave, so you can hear the sounds around you again.

It depends on the design of your earbuds.

It’s possible for them to be made so that they block your ear canal very tightly and only electronically allow you to hear certain sounds by piping them from their microphones to their speakers… or, they can be made so that you can normally hear what’s going on around you and they work some black magic to pump some special noise to block background noise out when you want it to.

Earbuds have special parts inside them that block out noise. To turn the noise cancelling on, you press the button that turns on the special parts. To turn off the noise cancelling, you press the same button again and the special parts stop blocking out noise.

Ear buds with noise-canceling technology use special microphones and other electronic parts to help block out background noise.

The microphones on the ear buds pick up the sounds around you, and then the electronic parts in the ear buds create a special sound that is the exact opposite of the background noise. This special sound is called an “anti-noise” sound.

When the anti-noise sound is played through the ear buds, it cancels out the background noise, so you can hear the music or other sounds that you want to listen to more clearly. This helps to make the music or other sounds sound more crisp and clear, even if there is a lot of background noise.
