What does earphone noise reduction mean?

Earphone noise reduction refers to reducing or eliminating the interference of external noise on the audio output of headphones by technical means.

Noise canceling headphones, as the name implies, are headphones that can reduce external noise. It uses a special technology, which can reduce the external noise through electronic equipment or mechanical structure, so that you can still enjoy clear and pure music or phone calls in a noisy environment. There are two main types of noise-reducing headphones: one is active noise-reducing headphones, and the other is passive noise-reducing headphones.

Active noise reduction headphones need to use electronic equipment for noise reduction. This earphone has a built-in microphone and circuit board, which can detect external noise and generate sound waves opposite to the noise in reverse, thus achieving the effect of canceling the noise. Passive noise reduction headphones achieve noise reduction through sound insulation materials. This kind of earphone generally adopts closed earmuffs and special materials, which can isolate the interference of external noise and let you listen to music or talk in a quiet environment.

Headphone noise reduction application scenario

Travel: On airplanes, trains or cars, the environmental noise is often very high. Using noise-reducing headphones can reduce engine noise, vehicle noise and other passengers' noise, and provide a quieter travel experience.

Working environment: There are often noises in the office, such as keyboard tapping, printer noise, colleague conversation and so on. Earphone noise reduction can help you concentrate, reduce the interference of external noise and improve work efficiency.
