The microphone on Xiaomi headphones is a frequent headache for users, especially when the interlocutor complains of a quiet voice, noise or complete absence of sound. The problem can be either hardware malfunctions or incorrect settings of the smartphone. In this article, we will analyze all possible ways to set up the microphone, from basic MIUI parameters to hidden Android functions that the manufacturer does not advertise.
It's important to understand that the algorithm of actions depends on the type of headphones (wireless/wireless), the phone model (Redmi Note 12, POCO X5, Xiaomi 13T, etc.) and the firmware version. For example, in MIUI 14, the audio menu has changed dramatically compared to MIUI 12, and we have taken these nuances into account and prepared universal solutions that work on 90% of the brand's devices.
If after all the manipulations the microphone did not work, at the end of the article you will find a checklist for diagnosing hardware problems and a list of Xiaomi service centers with official warranty conditions.
