Quick start guide
The Huawei Freebuds 4i can be connected with any device through Bluetooth and act as standard wireless earphones. However, to get all the extra features, you need the Huawei AI Life app. Pro tip – download it from the AppGallery or the QR code on the box because, as the company confirmed with us; the Google Play version might have issues with some non-Huawei smartphones.
The app allows you to check the battery charge levels and customize the buds’ controls – default is double-tap for play/pause, touch & hold is noise control modes. There are three of those modes – Noise cancellation, Off, and Awareness. While long press cycles through all of them, you can disable some of them through the app.
