Background

With the rapid development of scientific technology and the demand of people for life, earphones have been widely used, such as telephone communication and music transmission. Among them, a TWS (True Wireless Stereo) bluetooth headset has been widely used because it has a feature of enabling two channels to be separated wirelessly, thereby ensuring the cleanness and the experience of sound.

The working principle of the TWS is that the main earphone is connected with the main earphone through a mobile phone, and then the main earphone is quickly connected with the auxiliary earphone through a wireless connection mode, so that the real wireless separation use of the left sound channel and the right sound channel is realized, namely the left earphone and the right earphone of the TWS Bluetooth earphone can independently work without cable connection, and the use is convenient.

However, when the current TWS bluetooth headset is used for listening to music or making a call, some background noise or sharp noise can be generated in the headset, and too strong background noise or sharp noise can not only make people particularly irritate, but also submerge weak detail parts in normal sound of the headset, reduce the signal-to-noise ratio and dynamic range of sound, cause the quality of the heard normal sound to be damaged, and give users poor experience and use feeling. Where background noise refers to the total noise in the sound system of the headset, excluding the desired sound signal.

In view of the above problems, there is a need for an earphone to solve the above problems.
