Expert’s pick: HUAWEI FreeBuds 4 offer studio-quality sound, all-day comfort, and open-fit active noise cancellation

Most True Wireless Stereo (TWS) earphones on the market feature in-ear design, providing better physical noise cancellation with a better seal. They are also more stable as they fit better inside a user’s ear canal, so when we compare them to an open-fit design it shows this type still has its edge. One of the major reasons for choosing open-fit earphones is the comfortable feel – compared to in-ear earphones, open-fit earphones can provide a more comfortable experience. Moreover, open-fit earphones are now catching up in the active noise cancellation (ANC) technologies as some of them are already providing ANC features that usually only exist in high-end in-ear earphones.

Looking at the open-fit earphones on the market right now, the newly launched HUAWEI FreeBuds 4 rank right at the top, alongside the Apple AirPods 2 and Samsung Galaxy Buds Live. Here, we look at the HUAWEI FreeBuds 4 and see why they might be the right choice for consumers.

HUAWEI FreeBuds 4

Studio-quality sound

Sound quality is possibly the most important factor for most consumers when selecting their earphones. The HUAWEI FreeBuds 4 are equipped with a 14.3mm dynamic driver to produce greater and more impressive bass sounds. In terms of bass performance, these TWS earbuds adopt a newly upgraded bass enhancement engine, bass tube, and motherboard to form an independently sealed sound cavity. Using the HUAWEI AI Life app, users can record surrounding sound with ease, while the Voice Mode enhances voice pick and reduces environmental noise.

Open-fit Active Noise Cancellation

Aside from the dynamic driver, ANC technology also plays an important role. The earphones use an ergonomic simulation platform to objectively evaluate the comfort level. The HUAWEI FreeBuds 4 curvature and size are optimised and polished at the micro level to ensure they fit the ears better, providing better comfort and noise cancellation thanks to an airtight seal. They also adopt a dual-microphone hybrid de-noising technology that helps improve noise cancellation. These microphones, featuring a new internal structure, can help accurately pick up ambient noise. This can help avoid wind noise interference as well as improving sound pickup sensitivity for the internal microphone.

To enhance noise cancellation effectively across different wearing scenarios, HUAWEI FreeBuds 4 are the first open-fit earbuds in the industry to use Adaptive Ear Matching (AEM) noise cancellation technology. When noise cancellation is switched on, the earbuds automatically detect the users’ ear shape and determine the optimum noise cancellation setup for each user, resulting in the most comfortable noise cancellation experience. These TWS earbuds can achieve up to 25 dB, which is one of the deepest available in open-fit ANC TWS earphones.

Air-like comfort

Wearing comfort is key to ensuring an optimal user experience. The HUAWEI FreeBuds 4 have been revamped with 13 size optimisations that further reduced its body size. The earbuds also bring three enhancements to the overall curvature for a better fit. These optimisations not only enable a more pleasant wearing experience for long periods but also allow for strengthened ANC performance on the earbuds.

All-new interactions

Leveraging Huawei’s all-scenario device ecosystem and accumulated expertise in wireless connectivity, the HUAWEI FreeBuds 4 bring various connection features.

Dual-device connectivity: HUAWEI FreeBuds 4 supports dual device connection with various kinds of devices such as smartphones, tablets, PCs, smartwatches, and smart TVs under HUAWEI’s all-scenario devices. It also supports dual device connection with smart devices running on different operating systems such as Android, iOS, and Windows systems, achieving simultaneous connection with smart devices of different operating systems and brands.

Smart and personalised controls: The HUAWEI FreeBuds 4 comes with a smart interactive experience. You can effortlessly enable active noise cancellation, adjust the volume, answer calls, press play, and switch songs right from the earphone stems, with simple swipe/ double-tap/ long-press touch controls.

Huawei’s new open-fit ANC earphones, the HUAWEI FreeBuds 4, have been praised by many users for features such as studio-quality sound, enhanced open-fit ANC 2.0, comfortable wearing experience, and immersive audio quality, making them one of the most sought after open-fit earphones of 2021.
