More and more people are using bluetooth earphones. Meanwhile, some earphone problems will inevitably be complained by consumers. Among them, there is the problem of earphone echo.

One, mobile phone problem

Mobile phone use time is too long, some of the internal call components may be aging or failure, leading to the call in the process of echo. However, this can also happen if the new phone is of poor quality.

Solution: suggest the mobile phone to mobile phone repair point or mobile phone shop to repair.

Second, mobile phone Settings

The phone is set to record the call, in which case there may be an echo.

Solution: turn off the recording of the call so there is no response. Step: Settings - call Settings - extended Settings - whether incoming call is recorded - cancel.

Three, signal problem

During the call, signal interference may occur, which may affect the call quality of the earphone, thus causing the echo problem in the call. In addition, there may be sound reflection between buildings, weather and other factors to interfere with mobile phones or base stations, etc., will produce echoes.

Solution: if you encounter this situation, then please hang up the phone or choose the building is not dense place to make a phone call.

4. Bluetooth headsets

The main problem is the bluetooth headphone itself, especially the unreasonable design of the headphone cavity structure. Those who have studied physics know that in the process of sound transmission, if they encounter obstacles, they will inevitably produce echoes. If the structure is not designed properly, the echo will be too large, so that people can feel it clearly. If the microphone of bluetooth headset is close to the earpiece, it will be easier to produce echoes. If you disconnect the bluetooth headset to cancel the echo, and the bluetooth headset to connect the echo, then this is the problem with the headset itself.
