Noise-cancelling technology uses small microphones to detect external noise and then generates a sound wave that is 180 degrees out of phase with the incoming sound wave. This results in destructive interference, which cancels out the external noise. In noise-cancelling headphones, this technology is built into the headphones themselves. The headphones contain small microphones that […]

The main advantage of noise-cancelling headphones is that they can significantly reduce the amount of external noise that reaches your ears. This can be especially beneficial in environments with high levels of background noise, such as airplanes, trains, or noisy offices. By canceling out the external noise, noise-cancelling headphones can allow you to focus better […]
