Noise-cancelling headphones refer to a type of headphones that use some method to reduce noise. There are two types of noise-cancelling headphones: active noise-cancelling headphones and passive noise-cancelling headphones. The active noise reduction function uses the noise reduction system to generate reverse sound waves that are equal to the external noise, neutralizing the noise, thereby achieving the noise reduction effect.
