HUAWEI FreeBuds 4i

Quick View

Feedforward noise cancellation for crystal clear audio

A feedforward microphone is used to pick up background noise, and a reverse sound wave is generated in real time to eliminate the noise, bringing comfortable noise canceling.

Be aware of clear and natural ambient sound

You can switch to Awareness mode by touching and holding either earbud, which enables you to be aware of the surrounding sound without taking off your earbuds.

Fast Charging & Long Battery Life

With a large-capacity battery in a compact body, the HUAWEI FreeBuds 4i earbuds feature a long battery life with a low-power solution. With noise canceling disabled and the volume set to 50%, a full charge of the earbuds allows for 10 hours of music playback (in AAC format), or 6.5 hours of voice calls. A full charge of the earbuds and charging case allows for 22 hours of music playback, or 14 hours of voice calls.*
The earbuds support fast charging, and a 10-minute charge allows for 4 hours of music playback.**

Customized Speaker for Astonishing Sound

The HUAWEI FreeBuds 4i earbuds feature a 10 mm-diameter dynamic driver and an in-ear design for maximum comfort and stability.

Dual-microphone environmental noise cancellation during calls

Each earbud has two Micro-Electro-Mechanical System (MEMS) silicon microphones that support environmental noise cancellation during calls, effectively reducing ambient noise for high-quality voice calls.

Pop-up & Connect

The earbuds support Bluetooth Nearby Connection. When you pair your phone with a new device for the first time, a pop-up will appear and you can pair your device by one tap. Once your device is paired, it will be automatically connected and display the battery level on each use.
