(1) Better noise reduction effect

Passive noise-canceling headphones only have a partial isolation effect in the high-frequency noise range. Active noise-canceling headphones have a better denoising effect on low- and medium-frequency noises that people often encounter, such as "buzzing" air-conditioning noise, bus engine noise, and subway Engine friction sound will have obvious noise cancellation strength, which can reduce environmental noise of up to 25dB-35dB. At the same time, active noise-canceling headphones only makes appropriate noise cancellation effect for environmental noise, which is different from shielding all sounds. In terms of passive noise reduction, the effect of noise-canceling headphones is more prominent and even better.
