If someone asks you，What are the "not bad" noise reduction products in the current real wireless noise reduction headphone market?，Everyone should be able to tell one or two；But if you want to recommend a product that can experience the "most comfortable"，There are probably not many people who can answer it。
When most consumers buy headphones，It's easy to get stuck in functional comparison、In the confusion about parameter PK or what brand to choose，But the "comfort" of wearing is easily overlooked。I don't know how many people are not comfortable wearing it，The headphones I bought for several days，In the end, I threw it at home to eat ashes。
Speaking of comfort，Currently, the mainstream true wireless earphones are nothing more than in-ear and semi-in-ear styles，Half-in-ear headphones have a natural and comfortable wearing feeling，But the loss is that the sound insulation and noise reduction effect is poor；In-ear headphones are good to cancel noise，But it is not very friendly to users who are sensitive to ear canals，Many times consumers have to make a choice between "comfort" and "noise reduction"。
Lighter design，Bring a more comfortable wearing experience
Huawei launched FreeBuds 4 wireless headphones at Huawei's full-scene smart life new product launch conference on May 19, 2021，On the basis of providing comfortable wearing in the semi-ear shape，Semi-open active noise reduction 2.0 technology is adopted，Especially Huawei's self-developed human ear adaptive noise reduction technology，Able to use different ear types and wear conditions，Match more suitable noise reduction parameters，This will better ensure the noise reduction effect as a semi-in-ear headset。next，I will talk in detail about the trial experience of Huawei FreeBuds 4 wireless headphones in the past few days。
First of all, from the appearance，Huawei FreeBuds 4 wireless headphones are not much different from the previous generation product FreeBuds 3，But the charging case has shrunk by 6.3% in size、20.8% reduction in weight。Get started with this headphone，It is obvious that one-handed holding feels more comfortable，Also lighter and more portable，Especially for summer use，It won't feel like falling into your shorts pocket。
Next is about "comfort"，I'm personally sensitive to the ear canal，So half-in-ear headphones have always been my first choice。Huawei FreeBuds 4 wireless headphones The weight of a single headphone is 4.1g，Almost the lightest true wireless noise-cancelling headphones on the market。
To achieve more universal wear comfort，Huawei conducted tens of thousands of global ergonomic simulation experiments on 3D human ear models，And scientific analysis of the stress conditions of the headphones and the human ears，Design of headphone body based on ergonomic optimization，Thus, a wider range of human ear types，This proves the basic wear comfort of the headphones。
In terms of actual experience，The first feeling of wearing the headphones is light，So light I often forget its existence；Compared with the previous generation of FreeBuds 3，Huawei FreeBuds 4 wireless earphones have optimized the size of the headphone cavity and ear handle in arc，More even weight distribution，It fits the ears more closely when worn，For a day of commute、office、For leisure and entertainment，It can bring me a longer lasting and comfortable wearing experience。
Adaptive noise reduction technology for human ears，It can also comfortably reduce noise when you are half-in-ear
In general，Huawei FreeBuds 4 wireless headphones do a good job in comfort，But as a half-in-ear noise-cancelling headphone，What level of noise reduction effect can it reach? Don't say much nonsense，We first use the professional head recording device 3Dio dual-ear microphone on the subway、Real recordings in different scenes such as streets，Let's experience the noise reduction effect of this headset (to intuitively experience the noise reduction effect，Please be sure to wear your headphones to watch the video)。
Passed the scene test just now，You may feel that the noise reduction effect of Huawei FreeBuds 4 wireless headphones is not as large as that of in-ear headphones.，My daily experience is the same；This is because the semi-in-ear active noise cancellation mainly eliminates low-frequency noise，And for human voice、Broadcast information、Medium and high frequency sounds such as car whistle，Will be retained，Let users miss important information。
Huawei FreeBuds 4 wireless headphones adopt dual microphone noise reduction solution with better noise reduction effect，This is also the industry's first half-in-ear headphones that use dual-microphone hybrid noise reduction technology，Design of structural design in headphones through innovative microphone，Effectively improves the sensitivity of the microphone in the ear to residual noise pickup。
On the noise reduction algorithm，Huawei FreeBuds 4 wireless earphones are equipped with Huawei's self-developed AEM human ear adaptive noise reduction technology。After the headset is turned on, the noise reduction，It will automatically detect the user's ear shape and wear environment，And match the best noise reduction parameters from more than 10 kinds of noise reduction parameters，Save the user to manually adjust the operation。in my opinion，Let users make fewer choices，The best choice。
Sound quality balanced，More suitable for comfortable listening
Next, let's talk about sound quality，On the selection of sound unit，Huawei FreeBuds 4 wireless headphones use 14.3mm ultra-large diameter dynamic ring，and LCP liquid crystal composite diaphragm，While improving low frequency dynamics，middle、High frequency can also bring more details。This part of sound quality，Let's just use AirPods Pro to make a simple comparison，The effect will be more intuitive。Please continue to wear headphones，Listen to compare the sound quality of the two headphones。
In terms of listening，It should be said that the three-bands of both earphones are relatively balanced，There is no excessive sound dye，All are quite pleasant types。But in the details，The low frequency of Huawei FreeBuds 4 wireless headphones is still fuller and more flexible than AirPods Pro，Especially the expressiveness of pop music will be more abundant。
In a relatively quiet listening environment，Huawei FreeBuds 4 wireless headphones match moderate noise reduction depth，It adds some transparency to the sound in terms of listening。
Convenient connection、Operation experience
Currently，For the ecological products of major mobile phone manufacturers，The function of opening the cover pop-up window has basically become the standard，Huawei FreeBuds 4 wireless headphones are not out of the box；The headset is close to Huawei device，Support pop-up window function，Click to match easily。
also，Huawei FreeBuds 4 also supports dual connections to all scenario devices with different devices，Avoid the trouble of frequent disconnection of headphones between different devices。
Someone will definitely ask when you see this，"What if I use another Android phone or Apple phone?" Don't worry，Huawei FreeBuds 4 wireless headphones start from the underlying connection technology，Supports both Android、Smart devices on iOS and Windows systems remain dual-connected，Break different brands、Connection restrictions between systems，Let users say goodbye to the trouble of switching back and forth between multiple devices，Improve connection efficiency。
And in the [Audio Connection Center] of [Smart Life App]，Users can also see the 10 devices recently connected to the headset，Want to switch devices，Simply click on the target device to complete the switch，Help users achieve seamless connection experience in all scenarios。
In operation，Full touch control experience of Huawei FreeBuds 4 wireless headphones，It's very convenient for daily use，For example, touching the ear handle with a single finger can control music playback、Answer the call；Long press to control noise reduction on/off；Stroke the ear handle up and down to adjust the volume, etc.，All operations are at your fingertips。Here we need to emphasize the function of adjusting the volume，Really very convenient，No need to take out your phone to adjust the volume again。Although it's just a small feature，But it makes you feel that this is the experience that smart operation should have。
Looking at the current true wireless headphone market，Almost all products equipped with active noise reduction are in-ear headphones，However, semi-in-ear active noise reduction products have technical difficulties that are difficult to overcome in acoustically.，There are not many manufacturers who dare to get involved and launch products。This time, Huawei FreeBuds 4 wireless headphones have broken through the industry bottleneck in technology，Solve the pain points of the current real wireless noise reduction headsets that are difficult to achieve both [comfortable] and [noise reduction]，Meet the diversified needs of consumers under the demand for consumption upgrade，It also fills the market gap in semi-in-ear true wireless noise-cancelling headphones。It is predictable that，Wear more comfortable half-in-ear noise-cancelling headphones，It will undoubtedly become the focus of industry attention in the second half of this year。
