Huawei conducted tests with a prototype of the Huawei FreeBuds 4i earbuds and the accompanying software using the Huawei P40 phone.
Music playback test: The earbuds were connected to the phone over Bluetooth for music playback in the AAC format with the volume set to 50%. The battery was completely discharged until the music stopped playing from one of the earbuds.
Voice call test: The earbuds were connected to the phone over Bluetooth with the volume set to 50%. A voice call was then conducted until the voice could not be heard from one of the earbuds.
The battery life will vary depending on the device settings, usage, and other factors.
Standby time
Standby time with the earbuds fully charged, connected with a device, and outside the charging case: 2 days.

Features

Immersive stereo sound and switching between primary/secondary earbuds
After connecting to a Bluetooth device, the earbuds will play stereo sound through both channels when making voice calls or playing music. They intelligently designate one earbud as primary and the other as secondary based on their condition and battery level.
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 cancelling.
Maximum noise cancelling depth in the core frequency band: 22 dB
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.
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.
Fast charging and 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 cancelling 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.
(Conditions: The charging case has sufficient battery, the earbuds are fast-charged at room temperature, and the earbuds are used to play music in AAC format with a 50% volume level.)
Proximity pairing prompt upon opening the case
On phones running EMUI 10.0/Magic UI 3.0 or later, a proximity pairing prompt will be displayed each time you open the charging case for a rapid pairing or connection. The battery level of the earbuds and charging case will be displayed on the prompts.
In-ear design and surging bass
The Huawei FreeBuds 4i earbuds feature a 10 mm-diameter dynamic driver and an in-ear design for maximum comfort and stability.

Switch the audio output device (requires EMUI 10.1/Magic UI 3.1 or later)
Broadcast audio prompts (requires EMUI 10.0/Magic UI 3.0 or later)

Easy touch controls
Both earbuds use built-in capacitive sensors to achieve the double-tap and touch-and-hold shortcuts. You can change the shortcut settings in the AI Life app on a phone running EMUI 11.0/Magic UI 4.0 or later.

Convenient settings and updates in the AI Life app
The Huawei FreeBuds 4i earbuds work in conjunction with the Huawei AI Life app for you to switch between different noise control modes, customize noise-canceling settings, set shortcut operations, and perform OTA updates.
