HUAWEI has launched its latest True Wireless Stereo (TWS) Bluetooth earbuds, the HUAWEI FreeBuds 4.This new addition to HUAWEI’s numeric series of TWS earbuds inherits the world’s first open-fit active noise cancellation (ANC) technology from the previous generation. With open-fit ANC 2.0 technology, lightweight comfort, high-resolution sound quality and intelligent audio connectivity, HUAWEI FreeBuds 4 delivers not only on audio quality but takes the open-fit ANC listening experience to a whole new level.
In 2019, HUAWEI introduced the world’s first open-fit ANC TWS earbuds, the HUAWEI FreeBuds 3, finally allowing consumers to enjoy the comfort of an open-fit wearing style while also benefitting from the immersive ANC sound quality. After nearly two years of continuous R&D investment and accumulation of technical expertise, HUAWEI FreeBuds 4 has been launched, equipped with newly upgraded Open-fit ANC 2.0 technology which has improved noise cancellation at the hardware and software level, taking open-fit, comfortable noise cancellation to new levels.
The new HUAWEI FreeBuds 4 features dual-microphone noise cancellation technology to deliver upgraded noise cancellation performance. It is the industry’s first set of open-fit earbuds to use dual-microphone noise cancellation technology, which ensures that the microphones pick up ambient noise with far greater accuracy, reaching industry-leading levels. To enhance noise cancellation effectively across different wearing scenarios, HUAWEI FreeBuds 4 uses Adaptive Ear Matching (AEM) noise cancellation technology and are the first open-fit earbuds in the industry to do so. When noise cancellation is switched on, the earbuds automatically detect the user’s ear shape and determine the optimum noise cancellation setup for each user, resulting in the most comfortable noise cancellation experience. The HUAWEI FreeBuds 4 use a Liquid Crystal Polymer (LCP) composite diaphragm, which is support a frequency range of up to 40kHz, delivering high resolution sound quality. With no major quality loss, the treble part sounds richer and fuller.
What’s more, the HUAWEI FreeBuds 4 is equipped with a 14.3mm dynamic driver, producing greater and more impressive bass sounds. In terms of bass performance, the HUAWEI FreeBuds 4 adopt a newly upgraded bass enhancement engine, bass tube and motherboard to form an independently sealed sound cavity. Compared to FreeBuds 3, the HUAWEI FreeBuds 4 dramatically enhances the airtightness and acoustic pressure.
