Memory architecture methods to boost processor speed/ 2021
The search for the perfect pair of earphones can be quite confusing due to the abundance of options in the market. To make it even more difficult for us, earphones come in a number of styles and fits that affect the listening experience and comfort.
This is why it is important to first decide the kind of design one is looking for- whether it is in-ear or open-fit. Most True Wireless Stereo earphones in the market come with an in-ear design, providing better physical noise cancellation with a better seal. They are also more stable as they fit better into the ear so when we compare them to an open-fit design, this type still has an edge.
However, one aspect where open-fit earphones score better is on the comfort front. Compared to in-ear earphones, open-fit earphones provide a more comfortable experience and are now catching up in the active noise cancellation (ANC) technologies. Some of these earphones are now equipped with ANC features that usually only exist in high-end in-ear earphones.
A quick look at the best open-fit earphones in the market reveals that the current hot favourite is the HUAWEI FreeBuds 4. It has been loaded with some of the best features in the earphone market and easily scores higher than most other open-fit earphones by competitors within the same price bucket. Let’s take a look at the product and find out why HUAWEI FreeBuds 4 tops the chart for consumers in the UAE.
Studio-Quality Sound
Sound quality is possibly the most important factor for most consumers when it comes to selecting their earphones. 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. Using the HUAWEI AI Life app, users can record surrounding sounds with ease. It is also equipped with Voice Mode to enhance voice pick and reduce environmental noise.
Open-Fit Active Noise Cancellation
Apart from the dynamic driver, ANC technology is also one of the biggest highlights in this product. The earphones use an ergonomic simulation platform to objectively evaluate the comfort of the earphones. The HUAWEI FreeBuds 4 curvature and size are optimised and polished at the micro-level, which fits 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 can help accurately pick up ambient noise and also feature a new internal structure. This can help avoid wind noise interference, while also 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. HUAWEI FreeBuds 4 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 has been revamped with 13 size optimisations that further reduce its body size. It also brings three enhancements to its 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 brings various connection features. Some of them are:
i) 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 like Android, iOS, and Windows systems, achieving simultaneous connection with smart devices of different operating systems and brands.
ii)Smart and personalized controls: The HUAWEI FreeBuds 4 come 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 a 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. If you are planning to upgrade your earphones, it is one of the top options to consider.
