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.
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.

Key Features
The comfort of the earphones is also very important, the use of the earphones as well as other activities to take into account the durability is very important in portable audio and professional areas,
Portable audio headphones are relatively small, easy to be damaged;Professional earphones are frequently used and moved, and the cables are easily trampled and pulled.
The headphones are made to be very strong, and the parts are easy to repair and replace.
The sound quality of the earphone is more important than its technical performance. Since the shape of the head and the ears are different, a pair of earphones will have different hearing sensation to different people.
However, the hearing sense of earphones is different from that of speakers. The sound waves emitted by the earphones are attenuated and interfered in the air. They interact with the human head and ears.
