Ordinary earphones and active noise reduction earphones have obvious differences in positioning. Ordinary earphones are mainly to meet the daily needs of listening to music, watching movies, and chatting.Active Noise Cancelling Headphones， It's more like meeting everyone's basic listening needs, but often because of environmental reasons. Noise can interfere with the effect of listening to songs; and noise-canceling headphones are mainly to satisfy everyone in a noisy environment to better shield the external noise, so as to experience a better listening effect, such as in some noisy public places, actively reduce the noise during business trips. Noise headphones can isolate most of the external noise from vehicle noise. Listening to songs will not be disturbed by too much external noise, and you can enjoy high-quality music.
Active noise reduction: Active noise reduction headphones are much more complicated than ordinary headphones. Headphones need a built-in noise reduction module. It contains a microphone to receive external noise, and then through internal circuit calculations, play music on the headset. At the same time, the sound waves "inverted" from the external noise are added to cancel the noise, so that your ears can only hear the music itself, thereby achieving the effect of noise reduction.
Passive noise reduction, through the sound insulation material or special structure on the earphone, isolate the noise as much as possible. Passive noise-cancelling headphones mainly form a closed space by surrounding the ear, or use sound-insulating materials such as silicone earplugs to block external noise. The most common earphones designed with in-ear earplugs and large earmuffs can be classified as passive noise-cancelling earphones. If you compare the noise reduction effects of the two, in general, the effect of active noise reduction headphones is more obvious than that of passive noise reduction headphones, and it is also praised by more users who pursue ideal noise reduction effects.
As more and more consumers realize the advantages of noise-canceling headphones, the sound quality of noise-canceling headphones is getting better and better. Active noise-canceling headphones have also begun to become the ranks of people's daily use of headphones, not just for travel or office work. Noise reduction, active noise reduction headsets are also more like upgrade options for ordinary headset consumption.
