• As the noise pollution in the city becomes more and more serious, using ordinary earphone earplugs outdoors can only increase the volume to drown out the noise, thus not only can't enjoy the beautiful music, but also has a great impact on their hearing. The emergence of noise-cancelling earphones has solved this problem well.
• The development of headphone display is moving towards wireless and noise reduction. Wireless headphones are more free to use. With the development of science and technology, wireless transmission technology is gradually mature, ensuring the sound quality of wireless headphones .Another reason is the popularity of music on mobile phones and the birth of Bluetooth wireless transmission technology.
• The active noise cancelling headset has a noise cancelling device. The noise cancelling device USES the microphone to collect the sound from the outside world and emit the opposite sound wave to cancel the noise. Today, people are more and more concerned about their health. Noise-canceling earphones can better enjoy music outdoors and ensure the health of ears, which is the development direction of earphones in the future.
• With the development of earphones, the most important sound unit is the moving coil sound unit .After so many years of development, the moving-coil headphone technology has been very mature, but also encountered a bottleneck in the improvement of sound. In addition to static headphones, there are many derivative technologies for moving coil articulation units, among which the most widely used is the moving iron articulation unit.
• The ear muffs of the closed earphones adopt a completely closed structure, which can prevent the external sound from entering, so the pressure on the ears is greater, and the sound positioning is accurate and clear. This structure is often used in the field of professional monitoring .There are also some closed earphones with the sound field of open earphones, which can insulate the noise while still maintaining high quality sound.
• There is no strict regulation on the semi-open earphone, the sound can only go in or out, according to the use of the need to make design adjustments.
