Xiaomi Redmi 8 is still a popular budget smartphone, despite the release of newer models. One of the common tasks of users is to connect wireless headphones over Bluetooth. At first glance, the process seems simple, but many face problems: the phone does not see the device, the sound is interrupted or the headphones turn off after a few minutes. In this article, we will analyze all the ways of connecting, including hidden MIUI settings, and give recommendations for eliminating typical errors.
The Redmi 8 features Bluetooth 5.0 support, which provides a stable connection with most modern headphones, from the budget Xiaomi AirDots to the premium Sony WH-1000XM4. However, even with this version of the protocol, nuances can arise, for example, when connecting devices with the aptX codec or LDAC. We tested the instruction on various models of headphones and identified key points that guarantee successful pairing.
1. Preparation of headphones and phone for connection
