Immersive stereo sound and switch between primary / secondary earpiece
Once connected to a Bluetooth device, the earphones play stereo sound on both channels when you make voice calls or play music. It intelligently designates one earbud as primary and the other as secondary based on their status and battery level.

Pre-noise reduction for crystal clear sound
The forward-facing microphone is used to record background noise, and in order to filter noise, a backward sound wave is generated in real time, which results in convenient noise filtering. Maximum noise reduction depth in the core frequency band: 22 dB

Be aware of clean and natural ambient noises
Touch and hold either earbud to switch to Alertness mode, which lets you stay aware of the sounds around you without taking the earbud off.

Dual microphone for filtering ambient noise during calls
Each earbud comes with two Micro-Electro-Mechanical Order (MEMS) silicon microphones that support ambient noise reduction during calls, effectively reducing ambient noise for high-quality voice calls.

Fast charging and long battery life
With a large capacity battery and a compact body, the HUAWEI FreeBuds 4i earphones have a long battery life with a low power consumption solution.

With noise cancellation disabled and the volume set to 50%, a full charge of the earphones allows for 10 hours of music playback (in AAC format) or 6.5 hours of voice calls.

A full charge of the earphones and charging case allows for 22 hours of music playback or 14 hours of voice calls.

The earphones support fast charging, and a 10-minute charge allows for 4 hours of music playback.
