Huawei launches FreeBuds 4

Huawei has launched its latest addition to its line of True Wireless Stereo Bluetooth earbuds, the FreeBuds 4. Starting tomorrow (August 5), they will be available for pre-order with free gifts from Huawei website and stores for QR569. Huawei FreeBuds 4 has the open-fit active noise cancellation (ANC) 2.0 technology and delivers studio-quality sound as well as all-day comfort. They are also compatible with different operating systems including Android and iOS. Users can download the Huawei AI Life app to adjust settings or perform various controls such as wear detection, quick control, status query, noise cancellation and device management.
The Liquid Crystal Polymer composite diaphragm supports a frequency range of up to 40kHz to deliver high-resolution sound resulting in no major quality loss and trebles that sounds richer and fuller. The 14.3mm dynamic driver helps produce more impressive bass sounds.
A newly upgraded bass enhancement engine, bass tube and motherboard form an independently sealed sound cavity. Huawei FreeBuds 4 feature Adaptive Ear Matching (AEM) technology in open-fit earbuds for the first time. Utilising a high-sensitivity microphone, high-fidelity sound can be recorded supporting a sample rate of up to 48kHz to retain rich audio details. Using the Huawei AI Life app, users can record surrounding sound with ease as well as Voice Mode to enhance voice pick and reduce environmental noise.
The dual-microphone hybrid denoising technology helps improve noise cancellation. These microphones also features a new internal structure that can help avoid wind noise interference as well as improving sound pickup sensitivity for the internal microphone. This innovation alone can allow the earbuds to cancel out up to 25dB of noise when noise cancellation is turned on.
Huawei has also designed multiple parameters to help FreeBuds 4 achieve optimal noise-cancellation suitable on any condition. When users turn on the noise cancellation feature, AEM allows the earbuds to automatically detect the ear canal shape and wearing conditions and then assigns the best noise cancellation parameters from several data sets.
The Huawei FreeBuds 4 also supports dual device connections on any Huawei smartphone, tablet, PC, smartwatch or smart display, or any other smart devices running Android, iOS or Windows.
