Xiaomi: Pair a Bluetooth Device

Bluetooth accessories only connect automatically once your Xiaomi phone has stored their pairing information. The first time you use a headset, earbuds, or speaker, the device is not part of that list yet, so MIUI treats it as unknown hardware and will not link to it on its own.

Pairing tells MIUI to remember the accessory and exchange a security key with it. After that, the phone reconnects automatically whenever both devices are nearby and Bluetooth is switched on, without repeating the setup.

To pair a new device, open Tap on Settings ➔ Tap on Bluetooth, then wait for the accessory to appear in the list of available devices. Choose it with Choose an available device and confirm with Tap on Pair.

If the accessory does not show up in the list, it usually still needs to be switched into discoverable or pairing mode on its own side, separate from the phone settings. Once paired, connection problems later are rarely a pairing issue again; they are more often caused by the accessory being linked to another phone or by a stuck Bluetooth connection.
