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[1], 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.
A new benchmark for comfortable open-fit ANC and tranquil audio experience
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.
Up to 40kHz frequency response for more immersive listening
The HUAWEI FreeBuds 4 use a Liquid Crystal Polymer (LCP) composite diaphragm, which supports 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 adopts 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, and the volume of the bass tube is increased by 15%, which provides intensified resonance effect from the air and diaphragm.
HUAWEI FreeBuds 4, feature Adaptive Ear Matching (AEM) technology in open-fit earphones for the first time. By automatically detecting user’s ear shape and wearing condition, HUAWEI FreeBuds 4 can intelligently optimise the audio effect, allowing users to have consistent and high resolution audio quality, regardless of the wearing situation.
“Breathable” build: Ultimate wearing comfort packed in a sophisticated, lightweight design
Wearing comfort is the key to ensuring an optimal user experience. Compared with its predecessor HUAWEI FreeBuds 3, the HUAWEI FreeBuds 4 is revamped with 13 size optimisations, further reducing its body size for less weight – 4.1g per earbud. The HUAWEI FreeBuds 4 also brings three enhancements to its overall curvature for a better fit. The string of optimisations not only enables a more pleasant wearing experience and increased rigidity, but it also allows for strengthened ANC performance of the HUAWEI FreeBuds 4.
Smart audio connectivity
Leveraging Huawei’s all-scenario device ecosystem and accumulated expertise in wireless connectivity, the HUAWEI FreeBuds 4, bring various connection features, including proximity pairing, pairing via cloud information sharing, dual device connection and Audio Connectivity Centre. The earbuds can be connected to any EMUI based devices, from Huawei smartphones to tablets and Huawei PCs, delivering a truly seamless audio connectivity experience to consumers and ushering in an interconnection era.
