Even if you’re not a fan of wireless headphones and still have good wired headphones, you’re sure to use them for a long time to talk on the street when you make or receive calls . So when they stop working without there being an apparent reason, it’s like to get mad enough.
Something like this has happened to a good number of owners of a Xiaomi Mi 9 , who have reported in the forums of the Chinese community itself a problem that afflicts them and that has to do with the terminal not recognizing the microphone of their headphones. They hear without problems, allows them to raise and lower the volume on demand but at the time of making a call it is impossible for them to listen to them.
There is no response from the company
At this time, and when the forum continues to accumulate enough user contributions, some Xiaomi Mi 9 fail to recognize those microphones with brands of certain quality – as is the case of the AKGs – that some claim to have. Others, without specifying the manufacturer, report the same error so they imply that they are not using the officers that are delivered with the smartphone .
In normal conditions we could recommend that you update your terminal to MIUI 11, but seeing the string of errors that collects in this Xiaomi Mi 9 better leave it for later. So, what can we do to recover the microphone from the headphones?

Well look, we have bad news because the problem does not seem to be a hardware error of the phone and an incompatibility that does not affect all owners of this device equally, but a portion of them. That comes to indicate that those who are not reporting these problems are operating the microphone of their headphones. Maybe because the brand affects?
If a user of a Xiaomi Mi 9 uses the helmets that come with the terminal it is very possible that they do not suffer this problem, but if it is not the case and you have an especially good model of another brand, which has been giving you exceptional results for a long time , then that’s when the error can occur.
That is why in those same forums the simplest solution they have found until Xiaomi says something (or publishes a patch) is to buy compatible helmets , preferably from the Chinese brand (of those of just 4 euros) so that, when the In case, you use them only to talk and make calls. The moment you hang up and want to listen to music again, then yes, connect the good ones and enjoy their quality.
