On May 19, Huawei released the latest active noise-reducing true wireless headset FreeBuds 4, which not only continuously improved the sound quality analysis ability, but also greatly improved the active noise reduction performance of the headset, further improving the wearing comfort. Experiencing "comfortable noise reduction" has opened up a new track for real wireless earphone noise reduction and become a "decompression earphone" for people with sensitive ear canal.
What are the highlights and improvements of this headset? Next, we will answer through the freshly baked experience evaluation.
Huawei FreeBuds 4 wireless headset inherits the well-received design of the previous generation, and is further slimmed down through detail optimization: the headset box weighs only 38g, which is 20.8% lighter and 6.3% smaller than the previous generation. The complete round earphone box is not only beautiful and durable, but also round and light in texture. As for the opening and closing resistance of the earphone box, it is just right.
In addition to the ceramic white color scheme we evaluated, Huawei FreeBuds 4 wireless headphones also provide frost silver and honey red color schemes, among which frost silver is a new color scheme, and the earphone box and two earphones are very textured silver.
When pairing with Huawei, it is the first time to use your mobile phone and tablet device. When the system adopts EMUI 10 version 10 or above, Huawei FreeBuds 4 wireless headset will automatically enter the Bluetooth pairing state after opening the charging box for the first time. At this time, the surrounding Huawei mobile phones will automatically pop up a window to ask if they are connected, and the pairing connection can be completed with one click. It will be convenient to open the earphone box next time.
In addition, the newly released Huawei MateBook 16 notebook computer has also realized the quot shutdown connection quot to the PC, and can also display the remaining power of the current earphone box and earphone synchronously, which is convenient and intimate. If Huawei devices connect Huawei FreeBuds 4 wireless headset to log in to Huawei account, it supports the synchronization of pairing information on other Huawei devices logging in to the same account, which means that other Huawei devices can be seamlessly connected with one button without re-initial pairing.
If paired with a non-Huawei device, press and hold the button on the right side of Huawei FreeBuds 4 wireless headset box for a few seconds to enter the pairing mode, and Bluetooth can search for the headset and connect it. Because Huawei FreeBuds 4 wireless headset has rich enhancement functions, users are advised to download Huawei QuotSmart Life QuotaApp, through which more settings can be made, including firmware upgrade, quick control customization, noise reduction and sound quality.
After briefly introducing the design and control of Huawei FreeBuds 4 wireless headset, the main process is given, and the noise reduction and sound quality performance of this headset are introduced in detail. As you already know from the above appearance, Huawei FreeBuds 4 wireless headphones are not the in-ear design adopted by most active noise-reducing wireless headphones, but the semi-in-ear design, and the wearing experience is naturally more comfortable. The weight of a single earphone is only 4.1g. Compared with in-ear wireless headphones, Huawei Free Buds4 wireless headphones will be more comfortable to wear, especially after wearing for a long time, which can realize the comfortable wearing experience of quot Airyquot.
In order to enrich the functions of Huawei FreeBuds 4 wireless headset, in the research and development stage, Huawei scientifically analyzed the stress of headset and ear in eight areas through tens of thousands of ergonomic simulation experiments of global 3D ear model. Based on ergonomics, Huawei FreeBuds 4 wireless headset has been polished and optimized in radian, which makes the headset more stable and comfortable, fits the ear shape of most people, and is comfortable and stable to wear.
While improving the wearing comfort, in order to add active noise reduction function to the semi-in-ear design, Huawei has accumulated a large number of related self-developed technologies. In 20 19, Huawei became FreeBuds 3, and the world # 039 introduced the first semi-open wireless headset with active noise reduction. Huawei FreeBuds 4 wireless headset upgrade is equipped with semi-open active noise reduction 2.0 technology, including dual microphone hybrid noise reduction and Huawei's self-developed AEM ear adaptive noise reduction, which comprehensively improves the noise reduction performance of headphones in various scenarios.
Compared with Huawei FreeBuds 3 # 039' s single microphone noise reduction scheme, Huawei FreeBuds 4 # 039' s dual microphone mixed noise reduction scheme has revolutionized the structural design of the microphone, especially by adding a pickup tube structure next to the in-ear microphone, so that the noise in the ear can be better converged to the microphone along the pipeline, thus improving the sensitivity of pickup and significantly improving the noise reduction ability of headphones. AEM ear adaptive noise reduction technology supports matching the most suitable noise reduction scheme and wearing conditions according to more than ten noise reduction parameters of the wearer, and tailoring the best comfortable noise reduction experience for users.
During the actual measurement, we listened to music in office, street, subway and other common environments wearing Huawei FreeBuds 4 wireless headphones, and compared the sound effects before and after noise reduction. Before noise reduction is enabled, Huawei FreeBuds 4 wireless headphones, like other semi-in-ear headphones, need to turn up the volume to hear clearly in a noisy environment, and the external noise is still obvious.
The noise in the office is mainly human voice, and the decibel value of the volume is relatively low. After noise reduction is turned on, most of the nearby sounds are preserved, and the sense of space and depth of listening to songs is enhanced. After testing and enabling the noise reduction function in larger streets and subway cars, the low-frequency noise is obviously reduced, and the immersion of listening to music is obviously enhanced. As for high-frequency broadcast voice and car horn, it can still be heard after noise reduction, so users don't have to worry about missing important reminders because of noise reduction.
After many tests, Huawei FreeBuds 4 wireless headset has good noise reduction performance in both mild and moderate noise environments, and has obvious advantages for people who are concerned about long-term noise reduction comfort, especially those with sensitive ear canal. There is a specialization in the industry. If we pursue more extreme noise reduction effect in various scenes, it is more suitable to have in-ear wireless headphones at this stage.
Good noise reduction performance makes Huawei FreeBuds 4 wireless headphones more meaningful for improving sound quality. Although Huawei is not an acoustic debut, the progress of Huawei acoustics in recent years is obvious to all. Huawei FreeBuds 4 wireless headset adopts a more rigid LCP liquid crystal composite diaphragm, with a frequency response range of up to 40kHz and delicate high-frequency performance. 14.3 mm super-large diameter moving coil unit, with "low frequency booster engine", ensures that the low frequency is also at a high level.
As far as the actual listening sense is concerned, Huawei FreeBuds 4 wireless headphones can control all kinds of music calmly, comfortably and naturally. For ordinary users, it has reached the level of good voice.
In addition to the three core functions of wearing, noise reduction and sound quality, other performances of Huawei FreeBuds 4 wireless headphones are also remarkable. Equipped with a high-sensitivity microphone, it can record high-fidelity sound at a sampling rate of 48 kHz, and can be easily converted into a "high-definition studio" or a "mobile live studio". It is very practical for users who like to shoot Vlog or live broadcast. Thanks to the brand-new game audio coding technology, when used with EMUI system, the time delay of Huawei FreeBuds 4 wireless headset can be as low as 150ms, which ensures the integration of sound and picture in the game, and you can enjoy the most vivid game experience.
To sum up, I experienced the feeling of Huawei FreeBuds 4 wireless headset for a few days. The appearance with high face value and good texture can first leave a good impression. As a rare semi-in-ear active noise reduction earphone on the market, Huawei FreeBuds 4 wireless earphone has significantly improved its noise reduction ability compared with T.
