Why Xiaomi Headphones Donβt Connect to Phones: The Main Reasons
Mi True Wireless Earphones (including Basic 2, 2S, 3 and AirDots Pro) are designed to pair with Xiaomi devices as quickly as possible thanks to MIUI FastConnect technology. However, even with optimization, users face problems: the phone does not see the headphones, the connection is interrupted or the sound is transmitted with a delay.
πΉ Outdated firmware headphones or phone (especially relevant for models older than 2021).
πΉ Bluetooth profile conflict, where data from previous connections of other devices is stored in the phoneβs memory.
πΉ Hardware restrictions: some Xiaomi budget smartphones (e.g. Redmi) 9A POCO C31) Bluetooth 4.2 only supports, which can cause problems with Mi True Wireless 3 (requires Bluetooth 5.2).
In this article, we'll look at all the current connectivity options, including the hidden MIUI settings that speed pairing, and if your headphones have been connected before but are no longer identified, at the end there's a fault diagnosis section.

- Confirm the pairing on the phone and in the case (if required).
