Excessive noise has a great influence on the reproduction of music details. This is due to the masking effect of the sound: although all sounds will enter our ears, if there is a stronger sound and a weaker sound at the same time, We will feel the stronger sound is clearer and the weaker sound will be masked. To put it simply, although both the stronger sound and the weaker sound exist, and the weaker sound does not disappear in the presence of the stronger sound, but is covered up, making us "hearing" unable to hear.

Over-ear headphones were used to block noise by surrounding the ears, while in-ear headphones were made of silicone and other materials. Fill the ear canal to achieve the effect of sound insulation. In order to achieve a better noise reduction effect, manufacturers have built an electronic noise reduction system (active noise reduction) in the headset to achieve a better noise reduction effect.
