Semi in-ear earphones also reduce noise, Huawei uses technological innovation to lead industry upgrades

In an era where life has been heavily polluted by noise, seeking peace has become a bit extravagant; you may think I am a bit exaggerated, but every day when I see people wearing headphones in silence and meditating on the subway to and from get off work, I just I will feel: inner peace is so important to busy and anxious us.

Under this demand, active noise-canceling headphones began to appear in the market. But have you discovered that most of the current active noise reduction headphones are head-mounted or in-ear design. Such a design can improve the effect of active noise reduction in a more airtight way, but the shortcomings are also obvious, such as head-mounted headphones Stuffy, heavy, and not easy to carry; in-ear earphones are easy to make the ears feel “closed”. Most of these headphones sacrifice the user’s comfortable wearing experience in pursuit of noise reduction.

So can semi in-ear earphones that are more comfortable to wear also achieve good active noise reduction effects? In fact, many earphone manufacturers have also conducted research on active noise reduction of semi in-ear earphones in the past few years. However, due to the poor airtight design of semi in-ear earphones and the difficulty of semi in-ear noise reduction technology, many Brands have abandoned the research and development of semi in-ear earphones.

Huawei FreeBuds 4However, these brands do not include Huawei. In 2019, Huawei released the world’s first semi-open active noise reduction headhones——Huawei FreeBuds 3. In the following two years, Huawei continued to innovate and develop, and now finally found a new noise reduction solution more suitable for semi in-ear earphones, that is, the semi-open active noise reduction 2.0 technology carried in Huawei FreeBuds 4 wireless earphones, which includes With Huawei’s self-developed AEM human ear adaptive noise reduction technology and dual-microphone hybrid noise reduction technology, Huawei FreeBuds 4 wireless headphones finally achieve a balance between wearing comfort and active noise reduction, leading the industry upgrade with technological innovation.

The AEM human ear adaptive noise reduction technology mentioned here is a set of technologies developed by Huawei in order to allow different consumers to obtain a relatively good noise reduction effect under different wearing conditions. When the user turns on noise reduction, the headhones will automatically detect the user’s ear type and wearing conditions, and match the best noise reduction parameters from more than 10 noise reduction parameters, which is equivalent to customizing a dedicated earphone for the user’s ears Noise reduction parameters, so that different users can get the best noise reduction experience.

During the actual experience, the effect is obvious in the office environment, and the background noise can be significantly reduced. Moreover, while eliminating noise, what colleagues say to you and the broadcast in the office can be heard clearly, and important information is not missed while reducing noise.

Comfortable to wear + active noise reduction, Huawei FreeBuds 4 experience is more perfect

Compared with traditional head-mounted/in-ear noise-reducing headphones, Huawei FreeBuds 4 wireless headphones have the biggest difference in that they are more comfortable to wear. Compared with in-ear noise reduction headphones, although the design of in-ear earphones is also very light, long-term wearing will cause a sense of occlusion in the ears.

This is not the case with Huawei FreeBuds 4 wireless headphones. Not only does it have a 4.1g lightweight body, but it also introduces an ergonomic simulation design, and has undergone tens of thousands of repeated tests of 3D ear molds during the development process. , Which can meet the requirements of most users for wearing experience. The care in the design of these products ultimately made Huawei FreeBuds 4 light and insensitive in the actual wearing process, and it fits perfectly with the contour of the ears.

Among head-mounted, in-ear and semi in-ear active noise reduction headphones, some people may “blindly” believe in the first two designs and pursue the ultimate noise reduction. However, in addition to noise reduction, other users also pursue a sense of “balance”. Huawei FreeBuds 4 is the best example.

High-resolution sound quality + convenient connection, almost no shortcomings

While focusing on wearing comfort and active noise reduction, Huawei FreeBuds 4 wireless headphones also have great advantages in other aspects. For example, the 14.3mm dynamic driver, combined with the LCP liquid crystal composite diaphragm, has a frequency response range of up to 40kHz, making the high-frequency sound more delicate; the newly upgraded low-frequency enhancement engine makes the low-frequency sound more surging.

The connection between Huawei FreeBuds 4 and other devices is also very convenient. It can realize close and instant connection, instant sharing of pairing information, dual connection of smart devices, audio connection center and other functions, which can bring seamless switching and intelligent experience, and listen freely anytime, anywhere. music.

In addition, Huawei FreeBuds 4 wireless headphones also support high-definition recording function, which can achieve high-fidelity recording at a sampling rate of 48 kHz. For users who usually like to shoot short videos, Huawei FreeBuds 4 wireless headphones are still a very good radio equipment.


After a period of experience, I believe that many people will fall in love with the Huawei FreeBuds 4 wireless headhones, and it will become a must-have when going out every day. At the same time, Huawei FreeBuds 4 combines semi in-ear and active noise reduction into one design, which also solves the pain points of consumers and strengthens Huawei’s position in the field of TWS headhones.
