Instructions for connecting to the iPhone:
- Open Settings β Bluetooth and turn it on.
- Remove the headphones from the case and hold the touchpad for 3 seconds (the indicator should flash white).
- In the list of devices, find Redmi Buds XXX and tap it.
- Confirm the connection (no code required).

- π Reboot iPhone and headphones (put in the case for 10 seconds).
- π± Forget the device in Bluetooth settings (if it was already there) and repeat pairing.
- π Connect the headphones to another device (Android), then try connecting to the iPhone again.
