This is a brand new TWS headphone, officially announced on August 11. Compared to its predecessors, the Xiaomi Buds 4 Pro has many innovations and improvements. It’s naïve to think about it as an Apple AirPods rival, but this is one of the best alternatives.

The charging box adopts a new design with more rounded lines. The upper cover is treated with a high-gloss nano-NCVM coating process. However, the rest of the body has a matte surface.

The space capsule design is trendy nowadays.

The “space capsule” uses an open magnetic suction design. In simple words, there are multiple magnets built into the storage compartment. They help the lid to return to its place when you put it away.


The earbuds have a familiar appearance, identical to many other models available on the market. The headphone handle still supports the pressure-sensitive operation. Plus, it has a unique headphone air duct structure design on both sides to improve wind noise resistance.

Inside the earphone, we can see that there is a pressure relief hole in the sound cavity. There is also the charging contact.

Performance and functions

The Xiaomi Buds 4 Pro supports MIUI open-and-connect function. Simply put, once taken out from the charging box, the compatible Xiaomi smartphones will automatically detect and pair it with the headphones. When pairing, open the charging box near the device, the connection and pairing interface will pop up, and click to pair. At the same time, you can check the battery level in the pop-up interface.

In the mobile app, you can set custom gestures and adjust settings for functions such as intelligent hands-off and dual-device connection for wearing detection.

Active noise reduction is one of the functional upgrades of Xiaomi Buds 4 Pro. The maximum noise reduction depth of the headset can reach 48dB. This is sufficient to reduce the background noise by up to 99.6%. Also, the noise reduction bandwidth can reach up to 4000Hz. It supports 3-speed automatic noise reduction and 6-speed manual noise reduction. Plus, our protagonist supports three transparency modes: standard transparency, vocal enhancement, and ambient enhancement. At the same time, it comes with a 3-mic + bone voiceprint sensor to achieve efficient call noise reduction.

Here, we should focus on two points. First, after wearing headphones and turning on the noise reduction function, you can feel that the ambient noise is quickly and greatly compressed. Indoor headphones will almost completely reduce the noise generated by computers, conditioners, etc.

In the outdoor test, we can see that the 4000Hz ultra-wideband noise reduction advantage of the Xiaomi Buds 4 Pro has an important role. It not only filters out noise pollution but also avoids the hearing damage caused by listening to music at high volume.

Second, the Xiaomi Buds 4 Pro has wind noise reduction support. Here, this product performs outstandingly. The design of the air ducts on both sides of the earphone handle has indeed greatly improved the wind noise resistance of the earphones.

Powerful hardware matters.

Inside, the headphones host high-performance flagship chips with a 12nm process. They enable the headset to have the sufficient independent computing power and support innovative independent spatial audio functions. So the calculation of spatial audio listening sense no longer relies on smartphones. Thus, users can already freely implement multiple devices for cross-platform spatial surround sound.

At the same time, the headset has a built-in six-axis sensor, which can intelligently identify and dynamically track the direction of the head. It supports horizontal 360° rotation positioning, which helps the product to bring a 3D surround sound immersive experience.
