Xiaomi Mi Air 2 wireless headphones (also known as Mi True Wireless Earphones 2) remain a popular choice among users of the Xiaomi ecosystem due to the balance of price, sound quality and battery life. However, even experienced smartphone owners sometimes have difficulties with first connecting or re-pairing devices. This article will help you understand everything from basic settings to solving rare bugs.
The Mi Air 2 features Bluetooth 5.0 and Qualcommβs QCC3020 chip, which provides a stable connection to Xiaomi phones (especially on MIUI 12+). But even with modern protocols, users face challenges from missing headphones in the list of available devices to interrupting sound. We will detail each step, including hidden MIUI settings that can improve connection quality.
