It can probably be understood as the difference between automatic and manual adjustment of your phone's screen brightness. Adaptive noise reduction for Studio3 Wireless. As a big Bluetooth ear, battery life is an inevitable problem. The so-called adaptive is to evaluate the noise reduction level according to the surrounding environment. The noise reduction level in quiet environment and noisy environment is definitely not the same, and the relatively only noise reduction design can improve the battery life to a certain extent.

The difference between passive and active noise reduction:
< br >
1, noise reduction principle is different
< br >
Passive noise reduction is to fill the ear cup with sponge, and isolate the noise through the ear cup and sponge, which has certain requirements for the clamping force of the ear cup. If there is a gap between the ear cup and the ear with small clamping force, the noise reduction effect will be much worse.
< br >
Active noise reduction is to set an intelligent noise reduction chip in the ear cup. When the built-in pickup sensor of the headset senses the external noise, the intelligent circuit will generate a sound wave opposite to the external noise to offset the noise.

2. The price is different
< br >
Passive noise reduction production is simple, relatively cheap, generally tens of yuan to one or two hundred can be bought.
< br >
The technical requirements of active noise-cancelling headphones are high, and the price is generally more than 1,000 yuan.
< br >
3. Different applications
< br >
Passive noise-cancelling headphones can be used as labor protection headphones in factories, construction sites and other occasions. It is difficult to communicate with the person next to you when you wear noise-canceling headphones at work.
< br >
Active noise-cancelling headphones can also sense small sounds while shielding huge noises, without affecting communication, and are generally used in military, airport and other occasions.
Active noise reduction means that the noise reduction curve is fixed, and intelligent noise reduction means that the noise reduction algorithm is adjusted according to the wearing Angle position after wearing. Better user experience.
