Ear return means that you can hear your own voice and specific sound in the headset. It is composed of wired headset, wireless receiver and transmitter. It uses the signal frequency band other than Bluetooth to transmit audio, so as to achieve the return listening effect of 0 delay and 0 distortion. It also belongs to monitoring headset.
The difference between earphone and ear return is that earphone is also a part of ear return. Ear return is a function. The purpose of using ear return is to clearly hear your voice in a noisy environment and correct the slip of mouth and sound when hosting the performance. It is most commonly used in program hosting, stage performance, karaoke and other scenes.
Ear return is usually used with wired headset and wireless band receiver, and Bluetooth will not be used. When a singer sings, there will be a great delay due to the noisy environment and the sound field. If the singer doesn't return with his ears, he may sing by mistake and out of tune. He can't hear how he sings and can't keep up with the beat of the accompaniment. The singer's ear is actually playing the accompaniment, the pickup of his own microphone and the pickup of stage instruments, so that the singer can hear more clearly.
Many people will have questions, Bluetooth headset is so convenient, why not use Bluetooth? The reason is very simple. Now Bluetooth 4 2 and 5.0 Bluetooth transmission can not achieve 0 delay and 0 distortion, and can not better achieve real-time listening back. Moreover, the battery of Bluetooth headset will run out of power. If there is equipment interference signal on site, the Bluetooth headset may have intermittent sound, which will greatly affect the singer's performance on the stage. If you have used some karaoke microphones at ordinary times, you will know that the band also has the function of listening back, but there will still be a big gap with professional equipment.
With the continuous development of science and technology in recent years, ear return is widely used in the market, which also involves the fields of e-sports, education and so on. Shenzhen Tianyun Electronic Technology Co., Ltd. already has game earphones and ear back earphones for education. You can hear your voice in real time and real-time voice in game E-sports to ensure that your call is correct. The listening and speaking test in the education industry also adopts real-time listening back, which is very helpful for language and music learning.
