Huawei FreeBuds 4 Introduction
In today’s Huawei full-scene intelligent life conference showcased Huawei’s full-scene ecological strategy development and unveiled several new products. Among them, a much-anticipated new member of the Huawei FreeBuds family – the Huawei FreeBuds 4 wireless headphones make the debut.
According to the introduction, Huawei FreeBuds 4 this time pay more attention to wearing comfort, using ergonomic simulation design solutions, based on simulation platform, a large number of user research and other ways to optimize the new semi-in-ear design, and through 10000 + 3D real human ear model analysis, to bring the top wearing comfort.

In addition to the main body of the headphones, Huawei FreeBuds 4’s headphone box has also been carefully designed, using the same pure round design language as its predecessor, with exquisite detailing, also reducing the volume of the headphones by 6.3% and weight by 20.8%, making them more portable, while also supporting fast charging, with 30 minutes of charging to play music for 14 hours.
Functionality, Huawei FreeBuds 4 equipped with the new upgraded semi-open active noise cancellation 2.0 technology, semi-in-the-ear design, also brings more comfortable wearing comfort, will not cause a strong sense of pressure or swelling of the ear because of the deep ear canal, but also naturally brings a lower amplitude of noise reduction effect, listening more transparent, will not be too much noise reduction amplitude and the sense of ear pressure.
At the same time, Huawei FreeBuds 4 also uses a dual-microphone hybrid noise cancellation, noise reduction depth of up to 25dB, which allows the microphone to more accurately pick up the surrounding environmental noise, so that the headset generates more accurate noise reduction sound waves, thereby enhancing the active noise reduction performance, and by more sensitive pickup of residual noise in the ear, to achieve more accurate elimination of reverse acoustic noise, which is also in the current industry-leading open noise cancellation capability.
In addition, Huawei FreeBuds 4 is also equipped with Adaptive Noise Cancellation for the Human Ear (AEM), adaptive matching algorithm, when users turn on noise cancellation, the headset will automatically detect the user’s ear shape and wearing conditions to match the best noise cancellation parameters, which can automatically select the current best noise cancellation parameters according to different human ears or wearing conditions to achieve the best noise cancellation experience, which is equivalent to exclusive customization for each user.
In terms of sound quality, Huawei FreeBuds 4 is equipped with a low-frequency enhancement engine and a 14.3mm diameter large dynamic unit that enables a frequency response range of up to 40kHz, bringing high-resolution sound quality and making the music experience more “sonic”. High-fidelity sound, preserving the rich details of the sound.

In terms of connectivity, Huawei FreeBuds 4 also continues the advantages of dual connectivity for all-scene devices, pairing information sharing, etc. The connection pop-up function can be implemented on multiple devices such as Huawei phones and PCs, and the audio connection center can even display the last 10 connected devices, which can be switched by clicking on them, making the connection and switching more convenient than ever.
In terms of price, Huawei FreeBuds 4 is available in three body colors, namely Frost Silver, Ceramic White, and Honey Red, all priced at 999 yuan, and will be available for pre-order at 16:08 on May 19 and officially open for sale at 0:00 on June 1.
