Design And Build Quality

Charging Case

Overall, Xiaodu adopts a simple and elegant design that is heavily inspired by the AirPods 3 design. As for the charging case, it features a design in the shape of a square oval, rounded at the corners, very compact, small, and lightweight only 40g, made of matte white plastic with the brand logo of Xiaodu is embossed in grey on the front of the charger case.


There is also a long slot in the center of the front to open the case, which is surrounded by a built-in magnet for easy opening and closing with one hand. Once opened, there is a place for the earbuds with an automatic charging start.

Unfortunately, the bottom of the charging case is round so you won’t be able to put it standing. The most important thing is the presence of the Type-C charging port, which would have been better if it had been placed elsewhere, especially on non-wireless charging cases, And next to it is a LED that indicates the case’s battery status.


Xiaodu Du Earbuds

We are now moving on to the elegant, Xiaodu Du wireless earphone has a semi-in ear format with a small design, short stem, and matte white color, and most importantly, the shape is light about 3.7g only to be comfortable on the ear and with stability during movement. the strange thing here is these ear tips are not made of soft silicone, they are made of a single material similar to AirPods 2.


Also, the “L” and “R” are printed on the bottom of the headphone grip to differentiate the left and right ears. Next to the magnetic charging contact, there is a microphone pickup hole with good and clear sound reception during a call with the help of the noise reduction hole on the outside of the earphone, which cooperates with the microphone to accurately distinguish between human voice and noise. The upper side of the earphones comes contains a touch control sensor.

Touch Control Panel

To control the Du Smart Buds, there is a high-precision touch control panel on the top of the earphone which can achieve precise control with highly responsive touch sensitivity. The control consists of answering/rejecting a call, playing/pausing music, or you can assign a custom operation via the “xiaodu” application.


Xiaodu Du Smart Buds Waterproof

These Du Smart Buds have IPX4 waterproof, so they are protected from rain and sweat but shouldn’t be submerged completely in the water to avoid damage, to stay with you in the long run, and give you the freedom to effectively use the earbuds in any sports environment or otherwise.

How To Pair Xiaodu Du With Smartphone

Xiaodu Du Smart Buds offers strong compatibility with both IOS and Android devices and adopts Bluetooth 5.0 technology for stable and powerful transmission, lower delay, and smoother connection for high sound quality. And you can enjoy music up to 10 meters long even with thin walls between you and your device.

However, pairing in Xiaodu Du is the same as any wireless earbuds, all you have to do is open the charging case and they will automatically turn on and enter the pairing state.

Immediately after that, open the Bluetooth interface of the smartphone, the device name “Du smart buds” will be automatically recognized, click it, and the pairing is completed successfully. The pairing is done manually once, after that it is automatic and fast provided Bluetooth is enabled, just remove it from the box and use it.

The Xiaodu App For Xiaodu Du Smart Buds

The good thing is that there is an app for Xiaodu Du Smart Buds, which means that these Bluetooth headphones support personalization. The application here is available for Android and IOS, works smoothly with a simple interface.

Xiaodu Du Smart Buds Audio Quality

The Xiaodu Du Smart Buds has a great stereo effect, with high volume, perfect bass, and has well-defined tones, to deliver perfect full-range performance with a better sound stage, thanks to the driver with a 13mm dynamic unit and high woofer to deliver smooth, natural sounds of pop, rock, and other strong rhythms. The armature driver delivers powerful, more accurate bass to provide more detail and excels in soothing genres such as acoustic and classical. This is done via the high-definition AAC and SBC audio codec to deliver the best HIFI stereo for all music styles in this price range.


Call Quality

For calls, there’s nothing to complain about, you can listen with better clarity than other headphones. Xiaodu Du Smart Buds is budget earbuds that adopt ANC technology. The internal and external bidirectional microphones respectively pick up the internal and external ambient noise of the ear in order to generate a reverse sound wave to cancel out the noise. This creates a new depth noise reduction with good volume and little hiss, but a little muffled. It’s not a perfect microphone, but it’s quite audible for games and calls.

Noise Cancelation Technology

One of the strengths of the Xiaodu Du is the noise reduction technology, here comes the noise reduction aperture responsible for capturing environmental noise while using the Noise Cancellation (ANC) that uses an algorithm to process internal digital signals and reduce background noise when making calls to achieve clear voice. Even in a noisy environment, both sides of the call can be heard clearly.

So the sound here is satisfactory because it’s not too muffled and doesn’t make a whistling sound, but that doesn’t mean there is no noise at all. Overall, it works well enough for earphones of this size and price.


Delay In Earphone

The Xiaodu Du Smart Buds feature ultra-low latency technology of just 200ms, so you can watch videos or play online games on both iPhone and Android without noticeable audio delay, even in YouTube or Netflix app which is always a challenge on iPhone. However, it did well.
Unfortunately, there is a slight delay in audio when playing games, which is almost normal, and you can find it on most wireless headphones in this price range.

Recording Voice Notes

The voice feedback function is offered as an additional service to familiarize yourself with the capabilities of the headphones. It records voice messages and later converts them into text notes without much hassle through the system Equipped with a powerful voice recognition machine learning package made by Baidu, notes that this feature is currently only available for English, Chinese and Japanese.

To record audio, it is not enough just to have headphones, you have to resort to the application to activate the recording, after which you can remove the phone. The phone should not be removed away, because the conversation is written on it, for example, you can write down your conclusions and translate them into text, record interviews, of course, there are transcription defects, but it is acceptable. And for the correct perception of the sound by the assistant in the headphones, you need to speak clearly and not quickly.

However, you have to be aware that the headphones are used either as a headphone or as a voice recorder. Just as you cannot download the audio directly from the program, only the text can be copied.

Du Smart Buds Battery And Charging Time

In terms of battery, the Xiaodu Du Smart Buds charging case is equipped with a built-in 500mAh Li-Polymer battery. When you put the earphone into the charging case, the earphone will automatically enter into the charging state. The storage box itself can be recharged for 2 hours, then the earbuds can be recharged 3 times, which can be used for 3-4 hours with noise canceling off and 0-100% charging takes 1 to 2 hours, The case is recharged via USB Type-C at the bottom of the case.


If you are looking for a pair of wireless earbuds that look great and are reasonably priced, then the Xiaodu Du Smart Buds is a great option, and a good investment in this price category, not only is the design good or the compatibility, the quality sound is one of the main factors for choosing these headphones from great stereo effect and good specific tones. In addition to noise-canceling technology and a good battery lasts for a long time.
