The modern wearables market is oversaturated with offerings, but Xiaomi wireless headphones remain the benchmark for price-performance. Users are often lost in acronyms: Redmi Buds, Mi True Wireless, AirDots β to understand this nomenclature from the first time is almost impossible. The brand has successfully captured the segment of affordable audio, offering technologies that were only recently the lot of the premium class.
When choosing a device, itβs important to consider not only the cost, but also the ecosystem youβre used to. Xiaomi and Redmi smartphones provide native integration by opening pop-ups and allowing you to fine-tune the equalizer through the system menu. However, iPhone or Samsung owners can also make full use of these gadgets, although the functionality of the Mi Music or Xiaomi Earbuds app may be limited.
In this article, we will discuss in detail what technical parameters to look for before buying, you will learn how active noise cancellation differs from passive insulation, why the AAC codec is more important than Bluetooth 5.0 and how to avoid overpaying for marketing tricks.
Design types and form factors: inserts against plugs
The first thing that customers face is the choice of body shape. Xiaomi produces two main types of devices: intrachannel (plugs) and open (inlays). Intrachannel models such as the Redmi Buds 4 Pro are equipped with silicone mounts that are inserted directly into the ear canal. This provides excellent passive noise insulation and deep bass, but can cause discomfort when worn for long periods of time for some users.
Open models, like the Xiaomi Buds 4 (not the Pro version) or the old AirDots, don't have rubber nozzles. They lie in the ear without creating pressure. They have a more airy sound, but less bass, and little extraneous noise is drowned out. If you plan to use gadgets in the subway or a noisy office, you definitely should make the choice in favor of "plugs."
β οΈ Warning: If you have sensitive ears or a tendency to otitis, avoid wearing long-term intrachannel models.
Landing comfort is a subjective parameter that can't be remotely verified. Everyone's ear has a unique geometry. Some users complain that even the expensive Mi True Wireless Earbuds fall out while running, while the cheap Redmi Buds 3 Lite sit like infused.
Noise reduction technologies: ANC vs ENC
Marketing departments often confuse customers with the acronyms ANC and ENC indiscriminately. ANC (Active Noise Cancellation) is an active noise cancellation that actually silences the external hum (engine, air conditioning noise) with the help of a counter sound wave, which boasts flagship models like Xiaomi Buds 4 Pro or Redmi Buds 5 Pro.
In the budget segment, ENC (Environmental Noise Cancellation) is more common, and it doesn't take away the noise for you, it just clears the voice of the person you're talking to by cutting off background sounds for the microphone. Many people buy cheap Redmi AirDots in the hope of staying quiet on the plane, but they're frustrated because ENC doesn't create a vacuum of silence.
How does the ANC work?
Transparency Mode is a useful feature that lets external sounds in, allowing you to hear announcements in transport without removing your headphones. In Xiaomi devices, the implementation of this mode varies: in top models it sounds natural, in budget models it can add a characteristic digital sound.
Codecs and sound quality: understand bitrates
The quality of the audio you transmit depends on the codec you use. The standard SBC protocol provides basic quality, but compresses the sound quite strongly, losing detail. For iPhone owners, this is not a problem, since iOS does not support aptX, but for Android users, the availability of advanced codecs is critical.
The AAC codec is the gold standard for Apple and most Android smartphones. It provides a good balance between quality and energy consumption. However, if you are an audiophile and use an Android smartphone, you should look for support for aptX Adaptive or LDAC. These codecs allow you to transmit high-resolution sound (Hi-Res Audio Wireless).
| Codec | Bitrate (kbit/s) | Compatibility | Quality. |
|---|---|---|---|
| SBC | 320 | Universal. | Basic |
| AAC | 256 | iOS, Android | Good. |
| aptX Adaptive | 420 | Android (Qualcomm) | High. |
| LDAC | 990 | Android (Sony/Xiaomi) | Hi-Res |
Itβs important to understand that even LDAC support doesnβt guarantee studio sound if the drivers in the headphones themselves are weak. Xiaomi often puts good codecs in the Buds 4 series and higher, whereas in the Redmi Buds lineup, AACs are more often limited to saving battery life.

For maximum sound quality, turn on the Android developer settings to βLDACβ or βaptX HDβ, but be prepared for the fact that the deviceβs autonomy will decrease by 15-20%.
Autonomy and charging case
Average working time of modern TWS-The headphones from Xiaomi are from 4 before 7 The case usually provides more than one charge. 2-3 But the real number depends on the functions that are on: active. ANC High volume reduces battery life by almost half.
Charging speed is another important parameter. Flagship models support fast charging, allowing you to get an hour of listening after 10 minutes in a case. Some top-end versions, such as the Xiaomi Buds 3T Pro, support wireless charging according to the Qi standard, which is convenient, but increases the cost of the device.
β οΈ Attention: Lithium polymer batteries degrade over time. Do not keep the headphones completely discharged for a long time - this can lead to a deep discharge, after which the device will stop charging.
Wet protection is marked IPX. For sports and jogging in the rain, a minimum of IPX4 is required. Models without protection (or with IPX2) can fail from profuse sweating, so it is better to choose protected versions of Redmi Buds for the gym.
App and setting up the equalizer
Without installing the Xiaomi Earbuds app (or Mi Music on older devices), the headphone functionality is stripped down. It is through the software that the firmware updates occur, which often fix connection bugs and improve the performance of microphones. The touch controllers are also set up only there.
The equalizer allows you to adapt the sound to the genre of music. Presets "Bas", "Vocal", "Jazz" change the frequency characteristics. In advanced models, there is a graphic equalizer where you can manually raise high frequencies or remove the buzzing bottoms, which turns a budget device into a personalized audio player.
βοΈ Pre-purchase check
The app's "Hearbuds Search" feature can save you a day if you lose one of your earbuds. It causes your device to make a loud squeak. It also often hides the noise control feature in the settings, which allows you to switch modes (ANC On/Off/Transparency) by touching the leg.
The series is called Redmi Buds vs Mi Buds.
Redmi Buds is mass-market, where you get basic functionality, plastic body and good sound for a minimum of money. Materials are simpler, there's no wireless charging, and microphones can do worse with the wind. It's the perfect choice for your first TWS experience or as a spare pair.
The Mi True Wireless Earbuds series (or simply Xiaomi Buds) are flagships, using premium materials, the best electronics, support for LDAC, spatial audio and multipoint connectivity (to both devices simultaneously), the difference in price can be double, but the difference in experience from use is noticeable.
β οΈ Attention: Beware of fakes! the brand's popularity has spawned many copies. check the serial number on Xiaomi's official website and the print quality on the box. the original packaging always has clear barcodes and holograms.
When choosing between generations (for example, Buds 3 and Buds 4), it is worth looking at improvements in autonomy and the emergence of new features like adaptive ANC. Often the previous generation immediately after the release of a new one becomes cheaper by 30%, becoming a bargain.

The main rule of choice: do not overpay for the ANC, unless you plan to use headphones in noisy places. For a quiet room and office, a good passive insulation of a budget model is enough.
