Sound is one essential element that
completes the overall experience. Every day, we are surrounded by sound coming
from all directions and while it is something we are often used to, it
sometimes cuts us from what we actually want to hear.
Check out the HUAWEI FreeBuds 4,
Huawei’s latest True Wireless Stereo (TWS) Bluetooth earbuds that continues the
legacy of the open-fit earbuds with Active Noise Cancelation (ANC) technology
that started with the HUAWEI FreeBuds 3.
Offering studio-quality sound as well as
open-fit ANC and unmatched air-like comfort, the HUAWEI FreeBuds 4
doesn’t just work with Huawei products, but also with devices running Android
and iOS. Through the HUAWEI AI Life app, users are able to adjust settings or
perform various controls such as wear detection, quick control, status query,
noise cancelation and device management.
Immersive
high-resolution audio with studio-quality sound
While speakers can handle all frequencies
created by sound, the same is not the case with earbuds or headphones, which is
why there is a need to innovate on how sound can be perfectly replicated
despite the narrow frequency range.
With the HUAWEI FreeBuds 4, it uses a
classic 14.3mm dynamic driver with a lightweight yet durable diaphragm that
brings improved dynamic response to help avoid split vibrations that cause
distortions in audio output. The earbuds use a Liquid Crystal Polymer (LCP)
composite diaphragm made of polymer for greater durability that brings improved
middle and treble sounds. In various test, dynamic drivers that use an LCP
composite diaphragm can support a frequency range of up to 40 kHz which can
deliver professional-grade sound quality with richer and fuller trebles.
Using this dynamic driver isn’t enough,
and Huawei has implemented a bass tube on the earbuds to create a more
pulse-pounding bass. This tube connects to the rear chamber of the audible unit
with the external air holes and is part of a newly upgraded bass enhancement
engine, bass tube and motherboard that form an independent sealed sound cavity.
This results in an enhanced airtightness and acoustic pressure and increased
bass performance that is wasn’t possible before on a small earbud.
More than just the impressively rich bass,
clear vocals and rich details, the HUAWEI FreeBuds 4 also uses Adaptive Ear
Matching (AEM) technology for the first time in open-fit earbuds. Using this
technology, it can intelligently optimise the audio effect and output, allowing
users to have a consistent and high resolution audio quality no matter how
they’re wearing the earbuds.
Aside
from the hardware enhancements to bring rich treble and powerful bass
performance, 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.
Leading the industry with
open-fit noise cancelation
Earbuds that feature ANC usually come with
an in-ear design, but despite the technical challenges Huawei managed to bring
ANC to open-fit earbuds: the open-fit earbuds offer a more pleasant and super
comfortable wearing experience as the user is less likely to feel a build-up of
air pressure within.
Challenges like how the earbuds should fit
in user’s ears for absolute comfort as well as a proper noise cancelling
algorithm brought about the adoption of dual microphones used on the HUAWEI
FreeBuds 4. Together with AEM technology, it helps address the issue by
automatically adjusting the music depending on the user’s ears. When users turn
on noise cancellation, the earbuds automatically detects the ear canal shape
and wearing conditions and then assigns the best suited noise cancellation
parameters for the best listening experience.
Additionally, HUAWEI FreeBuds 4 has a
staggered wind-proof structure that prevents wind noise from being generated at
the source. This design effectively blocks strong winds from blowing directly
into the microphone, allowing for better wind-proof effects.
Ergonomic
design for an air-like comfort
More than just the performance, earbuds
should also offer comfort levels that will allow it to be worn for long
periods. In the case of the HUAWEI FreeBuds 4, Huawei created a 3D evaluation
system that mainly looks at the wearing comfort of earbuds from three elements
that include suction pressure, stability and stuffiness. Stress tests are then
done to simulate how the earbuds are worn. Using 10,000+ human ear models, the
HUAWEI FreeBuds 4 was created factoring in the comfort assessment on these tests
to guarantee an optimal wearing air-like comfort for all users.
An
audio assistant for a better lifestyle
The HUAWEI FreeBuds 4 can also work as an
external microphone when shooting videos. Thanks to the high-sensitivity
microphone, it is able record high-fidelity sound using a sample rate of 48 kHz
that help retain much if the detail on the audio being recorded. Low Latency
Mode is also supported on the HUAWEI FreeBuds 4 which is perfect for users who
love playing fast-paced games.
Most of the time users want to control
playback or answer calls without the need to take out their smartphones, which
is why the HUAWEI FreeBuds 4 feature intuitive controls built right on the
earbud. Tapping twice on the stem allows users to answer/reject a call,
play/pause music, play previous/next song and enable voice assistant while
swiping up and down will control the volume. Additionally, long pressing on the
steam of the earbuds can enable/disable noise cancelation.
In this current digital age, many users
typically own more than one device and it could be a hassle if they want to
connect the earbuds to multiple devices that would require to be set up every
time it is being used. HUAWEI FreeBuds 4 supports dual device connections
whether if it’s a Huawei smartphone, tablet, PC, smartwatch or even devices from
other brands.
In one scenario, when the user is watching
on the tablet and there is an incoming call on the smartphone, the tablet will
automatically pause the episode and the earphones will switch to the smartphone
for the user to pick up the call.
In staying true to its technological
innovations, the HUAWEI FreeBuds 4 joins Huawei’s line up of products that have
transformed the way users interact with devices. This is a true testament to
Huawei’s capabilities in delivering what the user wants and in turn taking audio
experience to the next level.
Meta Description: Take
your audio experience to next level with the HUAWEI FreeBuds 4 featuring Studio-quality
sound, open-fit Active Noise Cancellation and air-like comfort.
