It’s easy to get confused about the Mi Home ecosystem, as there are dozens of models with similar designs and names on store shelves. Xiaomi’s wireless headphones are divided into several distinct lines, each tailored to a specific user’s task, whether it’s sports, travel or studio sound. The main difference lies not only in price, but also in the signal encoding technologies and active noise reduction systems used.
Understanding these differences will help you avoid overpaying for unnecessary features or being disappointed in the lack of expected sound quality. In this article, we will take a closer look at the sound architecture, connectivity features, and key technical parameters that separate the budget from the premium segment.
Brand Hierarchy: Xiaomi, Redmi and Poco Audio
The first thing a beginner needs to learn is to split the product portfolio: flagship models are released under the main Xiaomi brand and often carry the Mi True Wireless or simply Xiaomi Buds label, which are equipped with better drivers, support for high-resolution codecs and advanced noise cancellation.
Redmi Buds' lineup is mass-oriented. Here you'll find great models for everyday use, but with compromises in body materials or no wireless charging. Redmi often uses time-tested chipsets, which provides stability but limits maximum audio quality.
Another important feature to mention is the Poco sub-brand, which makes audio devices with a focus on low latency gamer mode, which distinguishes Poco models from aggressive design and prioritizing response speed over bass depth. It is important not to confuse these lines, since the software for them can vary.
When buying, always pay attention to the logo on your charging case, which is the first indicator of what price category the device falls into and what level of driver support you will get in the Xiaomi Earbuds app.
Noise reduction technologies: ANC vs ENC
One key factor in how the models differ from each other is the type of noise cancellation used, with top-end versions equipped with an Active Noise Cancellation (ANC) hybrid system that uses microphones both outside and inside the earphone to quench external noise.
More affordable models are often limited to ENC (Environmental Noise Cancellation) technology, which is not noise cancellation for the listener, but a voice-clearing system when talking. ENC sifts out background noise for the interlocutor, but you'll hear everything that's going on with headphones.
⚠️ Please do not be fooled by marketing tricks where ENC It's called smart noise cancellation. If you're planning to fly in an airplane or ride the subway, you need an active system. ANC, not ENC.
In flagship models such as the Xiaomi Buds 4 Pro, noise reduction depths can reach 48 dB, which is the industry standard, while public sector companies can only offer passive noise insulation through tight fitting of mounts, which is also effective, but less versatile.
How to check for ANC?
Also, it's worth considering that the effectiveness of ANC depends on the density of the earbud to the ear, and even the most powerful system can't cope if you use the wrong size of the insert.
Codecs and sound quality: AAC, SBC, LDAC and LHDC
The quality of music playback is directly dependent on the data protocol, or codec. The basic standard for all wireless headphones is SBC, which provides acceptable but compressed sound. The next level is AAC, which is the standard for Apple devices and most middle-class Android smartphones.
Xiaomi’s flagship models boast support for high-resolution codecs like Sony’s LDAC or LHDC (Hi-Res Audio Wireless) which transmit three times as much data as standard Bluetooth, allowing you to hear details that are usually lost when compressed.
However, to take advantage of LDAC or LHDC, your smartphone must also support these codecs.Otherwise, the headphones will automatically switch to AAC or SBC, and you won't hear the difference between the budget and top-end model.
💡
For maximum sound quality, activate the LHDC or LDAC codec in your smartphone’s Bluetooth settings. The path is usually: Settings → Bluetooth → Press the gear next to the headphones → Sound quality.
The differences in the sound scene are also due to the size of the speakers. Top models often use a scheme with two drivers: one for low frequencies and one for high frequencies, which allows for a cleaner separation of instruments.
Autonomy and charging speed
Runtime is another critical parameter that varies greatly depending on the series: Budget models typically offer about 4-5 hours of listening with ANC enabled, while flagships can run up to 9 hours in economical mode.
The charging case in Xiaomi’s lineup often supports Qi wireless charging, which is rare for the Redmi series.In addition, top-end devices can charge faster: 10 minutes on the base give up to 2 hours of music, while budget employees can charge for an hour for a similar result.
| Model | Working hours (ANC on) | Case time. | Fast charging. |
|---|---|---|---|
| Xiaomi Buds 4 Pro | 9:00 | 36 hours | 10 min = 3 hours |
| Redmi Buds 4 Pro | 6 hours | 30 | 10 min = 2 h |
| Xiaomi Buds 3 | 5-hour | 20 | 10 min = 1.5 h |
| Redmi Buds 3 Lite | 4 hours | 18 | No. |
In real-world conditions with the ANC enabled, these figures should be divided by 1.5.
💡
Wireless charging and fast charging are the preserve of older models, and in the budget segment, you will have to settle for a USB-C cable.
Protection from moisture and ergonomics
The degree of protection from external influences is something that is often overlooked when buying. Most modern models are labeled IPX4, which means protection from splashes and sweat, which makes them suitable for training in the gym or jogging in light rain.
However, there are higher-security models that can even be washed under a tap, although submerging them in water is still not recommended. Cheap options may not have any certification other than basic dust protection.
Ergonomics is also different: flagships often have a stem leg for easy touch control, while some sports models are made in the form of "plugs" without a leg for better fixation in the ear when active movement.
☑️ Checking before buying for sports
Pay attention to the weight of the device. Heavy headphones can cause discomfort when worn for longer than two hours, while lightweight plastic models are almost not felt, but may sound less detailed due to the small size of the speaker body.
Ecosystem and software
Integration with Xiaomi and Redmi smartphones provides instant pairing through a pop-up and access to advanced settings. Users of other Android or iOS brands can also use headphones, but the functionality of the Xiaomi Earbuds app may be limited.
The app has equalizer settings, firmware updates, gesture reassignment and headphone search. Without a firmware update, headphones can run unstable or have microphone issues, so regular checks for updates are mandatory.
⚠️ Note: When reselling headphones, be sure to reset to factory settings through the app or by clamping buttons on the case so that the new owner can connect them to his phone without any problems.
In addition, some features, such as spatial audio or adaptive noise cancellation, work only in conjunction with certain models of Xiaomi smartphones that use special sound processing algorithms.
