Active-noise cancellation is a fairly intuitive process. It works by utilizing a series of external microphones on the headphones to be listening in to the external sounds of your surrounding. The headphones are then able to produce the opposite soundwaves to play alongside whatever song, podcast, or audiobook you have queued up. This cancels out the sounds from your environment so you only hear what’s being played. It can work wonders to block out the sound from a chatty office or engine of a plane when flying.

The Nothing headphones have four separate customizable levels for ANC, including a high, medium, and low settings as well as a smart adaptive mode which can seamlessly adjust based on your surroundings. When it comes time that you need to be made aware of your environment once more, you can switch over to transparency mode which allows for background noises to filter through.
Battery life with these headphones is remarkably long. Without using ANC, you can achieve a listening time of up to 135 hours on a single charge. If you are using ANC, you can expect up to 75 hours of playtime which is still a crazy long time before needing to charge it again. If you find yourself ever having forgotten to charge them, but you need them right now, no need to worry. A quick five-minute charge is enough to get these headphones working for up to eight hours (with ANC off).
