Xiaomi Buds 4 Pro experience: no longer rely on in-depth adaptation, noise reduction and battery life are improved

On August 11, Xiaomi officially launched a new generation of true wireless noise-cancelling headphones – Xiaomi Buds 4 Pro.

Judging from the description of the press conference, Xiaomi's headphone update this time is still longing for a comprehensive and all-round experience. Compared with the previous generation, Xiaomi Buds 4 Pro has a higher degree of completion in all aspects.

"Sexy" Design

Instead of the low-key matte matte black treatment featured on Xiaomi Buds 3 and Xiaomi Buds 3 Pro, Xiaomi Buds 4 Pro is replaced with a new color similar to champagne gold – "Xingyao Gold".

The outer cover of the charging box is mirror-finished, and the color is a lighter bright gold. The bottom of the charging box and the hinge are replaced with a matte champagne color. The matte treatment is very delicate, and the charging box feels very smooth.

It's just that the mirror surface will be a little impatient to wear and dirty, so it is better to bring a protective cover for daily use.

After opening the cover, it is found that the earphones are fixed on the groove through the internal magnetic structure, and the whole shape is like sitting on a curved bench in the form of an art installation. The earphones use the same bright and dumb staggered note-like design as the charging box, and with the color that fits the appearance of the charging box, the Xiaomi Buds 4 Pro will look a little less straight than the Xiaomi Buds 3 Pro.

When my colleagues around me saw the Xiaomi Buds 4 Pro unboxing, they suddenly said:

Xiaomi's new headphones? This design is kinda sexy.

Having said that, although Xiaomi has replaced the newly designed charging box, it still retains the physical buttons next to the charging port at the bottom. In this era when the pairing mode has become a lot of fun, it is still possible to maintain the most intuitive and traditional mode, which is worth encouraging for the Xiaomi Buds 4 Pro.

Back to the headset itself, the Xiaomi Buds 4 Pro headset continues to use the note-shaped ear handle design. The wearing feeling is similar to the Xiaomi Buds 3 Pro. The in-ear part can just fill the gap in the ear, and the pressure under the auricle will not be affected. Especially obvious.

Just like the previous generation, there is no way to achieve a wearing effect with a low sense of presence. If it is also compared with AirPods Pro, the foreign body sensation of Xiaomi Buds 4 Pro is still a little more obvious, and the fatigue refresh will still be faster.

For daily use, Xiaomi Buds 4 Pro will not have too obvious fatigue compared with the bean-shaped design that is completely fixed by the ear structure, and it is OK to wear it for a little longer.

The blocking filter of Xiaomi Buds 4 Pro earphones is transferred from the rubber plug to the mouthpiece to prevent earwax from easily falling into the earphones and difficult to clean.

The replacement silicone still has three sets of large, medium and small, and the medium size has been installed on the headset. As for the common memory foam cover for noise-cancelling headphones, Xiaomi does not come with it.

The silicone is treated with a similar skin-friendly treatment, and it is quite comfortable to wear. And the silicone part is thinner, so it can be easier to fit into the shape of the ear when wearing it. It's just the sound insulation of wearing it, and the Xiaomi Buds 4 Pro is not obvious.

Spatial audio that even works on the Switch

The functional updates of Xiaomi Buds 4 Pro mainly focus on noise reduction, battery life and fast charging, spatial audio, as well as adaptation and functional support.

  • noise reduction

Xiaomi said that the noise reduction depth of Xiaomi Buds 4 Pro can reach 48dB, which is a little more than 40dB of Xiaomi Buds 3 Pro.

In addition, Xiaomi officials also emphasized that the new noise reduction width and wind noise resistance have been updated. The new model uses a new anti-wind noise algorithm, which can reduce the impact of wind noise on use when users are cycling, running and other outdoor activities.

The Xiaomi Buds 3 Pro with a noise reduction depth of 42dB has no problem dealing with the daily office environment. This time, in the face of the Xiaomi Buds 4 Pro with an improved noise reduction depth, we deliberately moved the office to the construction site for testing.

In the environment with the highest level of noise reduction turned on, the Xiaomi Buds 4 Pro can handle most of the noise. The volume of music played in nearby cafes, as well as the conversations of people farther away, has been reduced. Conventional noise from the construction site, and noise from the ceiling when it rains, the presence of these sounds has also been greatly reduced.

Occasionally a loud noise or two can be suppressed by the Xiaomi Buds 4 Pro. Basically, if you have the music on and on, the people around you need to come and shoot you to hear it.

The sound insulation effect of the headphone cleaner is not too outstanding, but with noise reduction, there is no problem in concentrating in a noisy environment.

Xiaomi Buds 4 Pro is also equipped with Xiaomi's self-developed noise reduction algorithm, which has the function of adaptive adjustment and can adjust the noise reduction intensity by itself. The adjustment strength and change are relatively natural, and there will be no obvious instantaneous changes in ear pressure.

Users can adjust the noise reduction intensity through the headset settings menu and the "Xiaomi Headphones" app, and there are 6 levels to choose from.

Outdoor sports, the wind noise of Xiaomi Buds 4 Pro is not affected much, and there is no problem in general running and cycling environments. But considering safety, my priority of turning on ambient sound outdoors will be higher than wind noise processing. If this kind of position is not blowing directly against the air conditioner fan indoors, the Xiaomi Buds 4 Pro will have no problem.

  • Application and connection performance

In terms of connection performance, Xiaomi's emphasis in this update is on independence.

Xiaomi launched the "Xiaomi Headphones" application when the Xiaomi Buds 4 Pro was released. After the application is paired with headphones, full-featured adjustments can be made on it, including functions such as noise reduction depth, spatial audio switch, sound effect settings, etc., which can be completed on the application. .

The application can perform all operations, which means that Xiaomi Buds 4 Pro does not need to be restricted by deep adaptation, and Xiaomi and non-Xiaomi mobile phones can also be used. Compared with the Xiaomi Buds 3 Pro, which can only achieve full-featured adaptation on the Xiaomi Civic point, the new model is much more comfortable to use.

The connection performance of Xiaomi Buds 4 Pro has been enhanced. When the headset is connected to the A device, it can be switched by tapping the connection on the already paired B device. The response speed is the level of true wireless flagship positioning.

The touch response and delay are not a big problem. Although Xiaomi does not emphasize the minimum delay, the Xiaomi Buds 4 Pro basically does not feel the delay when playing games. Users who are still struggling with delays in 2022 should not need to worry.

  • spatial audio

Xiaomi Buds 4 Pro has updated support for spatial audio. The head tracking of the new spatial audio part supports 360° horizontal rotation of the head, which is larger than the horizontal 180° recognition range to cope with different types of devices and content.

Yes, Xiaomi Buds 4 Pro has been replaced with a new 12nm processor, which has stronger processing performance than the previous generation. It can achieve the spatial audio function independently of the connected device and realize the independence of the spatial audio function.

Now, Xiaomi has released the special app to release the limitation of function adaptation, and now non-Xiaomi mobile phones can also use the "Xiaomi Headphones" application to obtain all the functions of Xiaomi Buds 4 Pro. As long as the "spatial audio" function is turned on, the Xiaomi Buds 4 Pro can also use spatial audio when connected to other mobile phones.

Xiaomi also said that after the headset has the spatial audio function turned on, the spatial audio function can be used when connecting to other devices such as the Switch. Then if the user has other VR devices on hand, it is a simple spatial audio solution with Xiaomi Buds 4 Pro.

  • battery life

In terms of battery life, the Xiaomi Buds 4 Pro was tested at 50% volume with noise reduction turned off and AAC encoding turned off. Its stand-alone battery life is 9 hours, and with the charging box, it can achieve 38 hours of battery life, which is better than the Xiaomi Buds 3 Pro with noise reduction turned off. Still much higher. The battery life after deep noise reduction is turned on will be 20% longer than the previous generation.

The new model also supports 2W QI wireless charging. The headset can be charged from 0 to 100% in 30 minutes when the headset is put back into the charging box. The fast charge between the charging box and the headset is "charge for five minutes and play for 3 hours".

I didn't feel the pressure on battery life when I used it for three generations before, and I wore it for a long time during office hours. There is not much difference between switching to the new model now. It may be that the daily habit of charging once every two days cannot use the full battery life of the headset. It is not difficult to switch to charging once every three days.

Now the headset does not need to be deeply adapted, and the pop-up screen can appear on the Xiaomi mobile phone, so Xiaomi mobile phone users who like to charge it every day can pay more attention to the power.

Sound upgrades in the same direction

In terms of sound, the sound configuration upgrade of Xiaomi Buds 4 Pro focuses on the unit and algorithm, while the upgrade of the sense of hearing is mainly reflected in the details.

The Xiaomi Buds 4 Pro is replaced with a new 11mm custom dual magnetic moving coil unit. The unit uses an LCP liquid crystal polymer dome to enhance the low frequency element group. At the same time, Xiaomi optimized the design of the centering piece to reduce the effect of distortion.

The biggest change in the sense of hearing is the enhancement of the low frequency texture. The texture of the drum beat of the Xiaomi Buds 4 Pro is a little better than that of the Xiaomi Buds 3 Pro. The overall performance is solid and fuller, and the "digital sense" presented by the rebound will be weaker than that of the Xiaomi Buds 3 Pro. .

In terms of encoding support, Xiaomi Buds 4 Pro supports the latest LHDC 4.0 encoding, and the headset can support 96kHz Hi-Res music playback to cope with Tidal, MOOV and KKBOX, which also provide lossless streaming in wireless mode.

The details of the earphones are similar to those of the third generation, but the sharpening that the third generation deliberately highlights the details is missing, and the transition is much smoother than before. The vocals are handled properly, and the jerky feeling is not obvious. The position of the singer can be expressed by voice, and the distance from the background is not too close, and it will not stick together.

However, when dealing with some musical instruments, the Xiaomi Buds 4 Pro will still be a little vague, and the sound of the guitar is a little bit stiff. It would be better if it could be improved.

The head tracking effect of spatial audio is very responsive. When the sound moves, a transition is added in the middle, so that when you turn your head quickly, you will not feel like a singer or other sounding object suddenly flashes in front of you.

However, the initial firmware of the headset still has the problem of inaccurate sound positioning and occasional failure to return to the correct position. This should be solved by a software update later.

Comprehensive and all-rounder with a higher degree of completion

In general, the Xiaomi Buds 4 Pro is still an all-round and comprehensive headset. It's just that now the focus has shifted from "all-around" to "comprehensive".

The versatility of headphones is reflected in the richness of functions and experience.

Such as noise reduction, improved battery life, updated HRTF algorithm and the addition of new units, etc. The changes in configuration and performance are to make the headset perform better and become the basis for attracting users and satisfying experience needs.

The comprehensiveness of the headset, Xiaomi wants to reflect this time on the coverage of the device layer and the user layer.

The appearance of the control application "Xiaomi Headphones" allows more Android phones to experience the full functions of the Xiaomi Buds 4 Pro, avoiding the embarrassment that only the Xiaomi Civi can be fully used when the Xiaomi Buds 3 Pro is first released, and also increases the applicability of the headset. scope.

Not only Xiaomi mobile phone users can choose Xiaomi Buds 4 Pro, users of other mobile phones or smart devices can also become Xiaomi Buds 4 Pro users. This should be the change Xiaomi wants to see now.

Just as the original intention of technology inclusiveness is to never abandon anyone, the comprehensiveness of the product should also go in the direction of wide adaptation and lower adaptation threshold.

Now in addition to Xiaomi, many mobile phone manufacturers have launched true wireless earphone products with low adaptation threshold and full-featured presentation. Perhaps in the future, when we choose true wireless products, we can be less restricted by brands and return more focus to the function itself and experience.

"Buy it, it's not expensive."
