What is a noise-canceling headset? What is the difference with ordinary headphones?

Noise-cancelling headphones refer to a kind of headphones that can achieve noise-cancelling effects by using a certain method. At present, noise reduction headphones are divided into active noise reduction headphones and passive noise reduction headphones

Active noise reduction: the noise reduction system produces opposite sound waves from outside noise to cancel noise reduction

Passive noise reduction: Noise reduction is carried out by physical means, the earphone is protected into a closed space to achieve the noise effect, or the external noise is blocked by materials such as silicone earplugs.

The effect of active noise reduction is better than passive noise reduction, so active noise reduction headphones are more expensive. Many mid-to-high-end noise reduction headphones on the market still have a lot of playability, transparent mode, noise reduction mode, etc., which can meet many of our different needs.

The audio decoding, sounding unit, and tri-band effects of noise-canceling headphones are introduced below.

Audio decoding: The audio decoding used by mid-to-high end headphones is generally AAC, AAC+SBC, APTX. APTX is currently the most advanced audio decoding, but there are many noise-reducing headphones that do not achieve the effect of APTX. They are just exaggerated. And audio decoding is "dead", while human ears are "live". Different people have different requirements for sound quality. There is no need to grasp the most advanced audio decoding. AAC+SBC, AAC is already very good!
