technicality

Many people mistakenly think that Buds 3 is just Bluetooth ears, but in fact it involves adaptive noise cancellation with AI, dynamic titanium-coated drivers and even a special chip for synchronization with the Xiaomi ecosystem. If you want to understand how these headphones interact with a smartphone, why they sometimes “glutch” and how to squeeze the most out of them, read on. We tested them with different devices (from Redmi Note 12 to iPhone 15) and are ready to share honest conclusions.

We'll warn you right away: Buds 3 behave differently depending on the firmware of the smartphone. MIUI 14+ They're 100% open, but with iOS or older versions of Android, some of the features will be unavailable.

Architecture and technical characteristics: what is inside the headphones

At the heart of Xiaomi Buds 3 is a dual driver system: a 10mm titanium-coated dynamic emitter is responsible for medium and high frequencies, and a separate balance reinforcement driver is responsible for low frequencies, which allows you to achieve clear sound without distortion even at maximum volume, but this is only the tip of the iceberg.

The main “brain” of headphones is a chip Qualcomm QCC3071, It's optimized for real-time audio processing:

• 🎵 Codec AAC High-quality audio transmission (especially important for Apple devices)

Special attention should be paid to the active noise reduction system (ANC). Buds 3 uses a hybrid circuit with 3 microphones on each headphone:

• 🤖 AI algorithm – generates anti-noise in real time (up to 40 dB of suppression)

Fun fact: Buds 3 features Xiaomi TrueSound technology that analyzes the shape of your ear and adjusts the sound to your anatomy. This is not a marketing ploy - the headphones really "adapt" to the user in the first 5 minutes of use.

How to connect Xiaomi Buds 3 to a smartphone: step-by-step instructions

The process of pairing depends on the type of device. Xiaomi/Redmi/Poco s MIUI 12+ The headphones automatically connect when you first open the case cover -- just confirm the connection in the pop-up window -- but the owners of other Android devices or iPhones will have to do it manually.

Branded application Mi Earphones: hidden settings and chips

Without the Mi Earphones app (available only for Android), you only use Buds 3 at 50% of its capabilities.

• 🎛️ Set up an equalizer (5 preset profiles) + custom)
• 🔇 Regulate the level ANC (3 modes: light, balanced, maximum)
• 🎮 Enable game mode with a delay of 88 ms
• 🔋 View usage statistics and case/earphone charge level
• 🔄 Update the firmware (critical for stability!)

The most useful function is “adaptive”. ANC". The algorithm analyzes the surrounding noise and automatically switches between modes, for example, in the subway will turn on maximum suppression, and in a quiet room - light:

1. Open Mi Earphones.
2. Go to Settings. ANC → Adaptive regime.
3. Turn on the switch and confirm access to the microphone (need to analyze the noise).

Another hidden feature is Transparent 2.0, which, unlike the standard mode, uses a neural network to amplify voices in noisy environments, which is useful if you're talking in a cafe or outdoors, but you don't want to take your headphones off.

⚠️ Note: Mi Earphones app doesn't work on iOS, iPhone owners only have basic features available (ANC, It's transparent, gesture control, but without fine-tuning. You'll have to borrow an Android device to update the firmware.

Handling gestures and voice: a complete list of commands

Xiaomi Buds 3 supports 5 gesture types and voice control via Google Assistant or XiaoAI (for the Chinese version).

To reassign gestures:

1. Open Mi Earphones.
2. Go to Settings. → Gesture management.
3. Select the headphone (right/left) and action.

For voice control:

• On Android: Hold any headphone for 2 seconds to activate Google Assistant.
• On iOS: Voice Assistant only works through Siri (configure Settings) → Siri and search).

1. Clean touch panels (wipe with an alcohol napkin).

2. the density of the headphones to the ears (with weak contact, touches are not recorded).

3. firmware version (old versions had triple-touch recognition bugs).-->

Problems and solutions: why Xiaomi Buds 3 may not work

Even these advanced headphones have typical "diseases," and here are the most common problems and proven ways to solve them:

1. Headphones don't connect to the phone

• 🔌 Check that Bluetooth is on and the headphones are paired (the indicator flashes white-orange).
• 📱 Nana MIUI Try to disable Quick Connection in Settings → Connections → Bluetooth.
• 🔄 Reset the headphone settings (press the button on the case for 10 seconds).

2. The sound is interrupted or "breaks"

• 📶 Check the distance to the phone (maximum 10 meters without obstacles).
• 🎵 In Mi Earphones, turn off aptX Adaptive and switch to AAC (sometimes helps with interference).
• 🔋 Case charge below 20%? Connect it to charge - at low charge, communication stability drops.

3. ANC It does not work or slightly suppresses noise

• 🎧 Check the density of the adjoining ambushes (should completely close the ear canal).
• 🔇 In Mi Earphones, update the firmware - in older versions ANC worse.
• 🌪️ In windy weather ANC It can be "going crazy" - that's normal (microphones catch gusts of wind).

4. Quickly discharged

• 🔋 Turn off the game mode and aptX Adaptive – they put the battery down hard.
• 🎵 Turn down the volume (at maximum the headphones will discharge for the 3-4 hour).
• 🌡️ Avoid using at temperatures below 0°C – Lithium polymer batteries lose capacity in the cold.

💡

If the headphones are getting worse after the firmware update, you can't roll back, and the only way out is to wait for the next update or reset to the factory.

Comparison with competitors: which is better – Buds 3, AirPods or Galaxy Buds

• 🎛️ Do not install custom firmware - this deprives of warranty and can disable headphones.

💡

If the headphones have been unused for a long time (more than a month), charge the case to 100% before the first switch on, then discharge to 0% and recharge. This calibrates the battery controller and prolongs its life.

⚠️ Warning: If the headphones start to "wheez" or turn off after falling or getting moisture, do not try to disassemble them yourself. Buds 3 uses adhesive joints, and if you open the membranes of the drivers, you can damage them if you do not slouch. Contact the Xiaomi Service Center (the warranty is valid for 12 months from the date of purchase).
