Neighbors’ decoration noises are distracting, various noises in commuting subways ruin the mood, and noisy people in the office reduce office efficiency… Long-term exposure to a noisy environment will bring many negative effects on life, study, and work. A true wireless headphone with active noise reduction, it can give everyone a quiet and private space. Therefore, both consumers and headphone manufacturers are pursuing the depth of noise reduction to achieve the ultimate quiet effect.
In order to meet the needs of consumers, manufacturers have resorted to their best efforts, combining active noise reduction + passive noise reduction, and have been involved in the “involution” of the competition parameters. All consumer electronics products go through such a process: the emergence of a new blue ocean, the entry of many manufacturers, the rapid advancement of technology, the decline of average prices, and the upgrade of consumer demand, the next stage of product iteration begins. After the competition in the depth of noise reduction has become saturated, more and more consumers are beginning to pay attention to the wearing comfort of headphones, hoping to achieve the best of both worlds of “noise reduction + comfort”.
People gradually realized the importance of wearing comfort for true wireless earphones, and began to further put forward the requirements for comfortable wearing based on the depth of noise reduction. But it is not easy to achieve both, which requires a strong accumulation of noise reduction technology and excellent industrial design capabilities. On May 19th, Huawei released the latest active noise reduction true wireless headphone——FreeBuds 4, with a fully upgraded semi-open active noise reduction 2.0 technology and a universal headphone appearance based on massive data, completing the noise reduction performance and comfort Wear the perfect fusion between the two.
| Comprehensively improved noise reduction experience
Comfortable noise reduction, noise reduction is of course the key. Semi-open active noise reduction technology has a high threshold, so few products are launched in the industry. In 2019, Huawei launched the world’s first semi-open active noise reduction true wireless headphone Huawei FreeBuds 3. After two years of continuous R&D investment and technology accumulation, Huawei FreeBuds 4 wireless headphones have brought an upgraded semi-open active noise reduction 2.0 technology, and for the first time in semi-in-ear headphones, Huawei’s self-developed human ear adaptive noise reduction, The dual microphone mixes two noise reduction technologies.
Through the human ear adaptive noise reduction technology, the headphone will automatically detect the user’s ear type and wearing conditions, and provide the best noise reduction plan from more than 10 noise reduction parameters. To put it simply, the Huawei FreeBuds 4 wireless headphone can tailor the most suitable noise reduction solution to the user’s auricle shape and wearing conditions. The dual-microphone hybrid noise reduction technology can effectively improve the sensitivity of residual noise pickup, allowing the microphone to more accurately pick up ambient noise, so that the headphone can generate noise reduction waves more accurately, which greatly improves the active noise reduction of this headphone performance.
| Air feel comfortable to wear
The comfort design of the headphone is a test of the manufacturer’s industrial design capabilities. For this reason, Huawei has established an ergonomic simulation platform, through more scientific and objective ergonomic simulation experiments, to make a more credible comprehensive evaluation of the comfort of the headphone. Huawei collected tens of thousands of real user ear canal data from all over the world, established a 3D model, and analyzed the stress of the headphone and the human ear in 8 regions, and based on ergonomic optimization to carry out the appearance design of the Huawei FreeBuds 4 wireless headphone , Make micron-level adjustments to the body of the headphone to meet the comfortable wearing needs of most users.
At the same time, the weight of a single headphone of Huawei FreeBuds 4 wireless headphone is only 4.1g, which is almost the lightest ANC headphone at present. It not only makes the wearing lighter and firmer, but also decodes the “optimal solution” for more consumers to wear comfortably. When wearing it, it really feels as light as a feather, without any discomfort or burden.
| High-quality listening experience
The “initial heart” of headphones is used to listen to music. Having high resolution capability and restoring good sound quality is also an important performance of headphone comfort. Huawei FreeBuds 4 wireless earphones use a 14.3mm large-size sounding unit. Under the action of the LCP liquid crystal composite diaphragm, the high frequency is richer and more delicate; with the new low frequency enhancement engine, the low frequency sound quality is more surging.
I chose “渡口” (Cai qin) and “Opera2” (Dimash) for listening tests. The drum beat in “渡口” is powerful and powerful, and the human voice is also penetrating, bringing a pure listening experience. When playing “Opera2”, Huawei’s FreeBuds 4 wireless earphones are also very clear in the high-pitched performance, the dolphin sound is straight through the soul, there is no sound break, and the layers of various instruments are clear.
Huawei FreeBuds 4 wireless earphones solve the pain points of consumers through the semi-open active noise reduction 2.0 technology, comfortable wearing experience of air and high-resolution sound quality, and open up a new track for true wireless earphone noise reduction with “comfortable noise reduction” . At 16:08 on May 19th, Huawei FreeBuds 4 has been pre-sale on Huawei Mall, Tmall, JD and other platforms, priced at 999 RMB, and officially launched at 00:00 on June 1.
