Unmatchable open-fit noise cancelation
The HUAWEI FreeBuds 4 has adopted the dual-microphone hybrid denoising technology that helps improve noise cancelation. These microphones can help accurately pick up ambient noise and 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 25 dB of noise when noise cancellation is turned on.
