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. 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 . The closer the fit of the earbuds, the greater the noise cancellation effect. Smaller ear cavities allow the earbuds to achieve a greater noise cancellation effect than larger ear cavities. It is recommended to maintain a close fit when wearing the earbuds to maximize the noise cancellation effect.
The earbuds 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. Up to 40kHz frequency response for more immersive listening,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 enhance 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. It will be supported by OTA upgrade in the future.
When ANC is turned off, HUAWEI FreeBuds 4 offers 4 hours of continuous music playback.
Together with the charging case, it can achieve 22 hours of music playback. If the ANC is
turned on, it can offer 2.5 hours of continuous music playback. Moreover, the industry-leading
quick charge technology provides 2.5 hours of audio enjoyment from a 15-minute charge, so
users do not need to worry about the battery level when they are out and about or in a hurry.
