Connecting Huawei headphones to Xiaomi smartphone: a complete guide to problem solving

Compatibility across brands is a frequent headache for users, especially when it comes to connecting Huawei wireless headphones to Xiaomi smartphones, where manufacturers use their own protocols and branded chips, while in practice, 90% of problems are solved with the right sequence of actions and knowledge of several technical nuances.

In this article, you will find not only basic pairing instructions, but also a breakdown of typical errors (for example, when the headphones are not detected or are connected with a delay), as well as hidden MIUI settings that will improve the sound. We tested the process on models from Huawei FreeBuds 3/4/5 to FreeBuds Pro 2 and Xiaomi 11/12/13 series, Redmi Note 10-12, POCO F4/F5 – all solutions are universal.

Why Huawei and Xiaomi may be at odds with connectivity

The main reason for the difficulties lies in different ecosystems: Huawei is actively promoting its Huawei Share protocol and proprietary LHDC codec, and Xiaomi optimizes devices for Mi Sound Enhancer and AAC/aptX.

• 🔹 Headphones can be connected in low quality mode (SBC instead LHDC/aptX)
• 🔹 The latency (sound delay) is achieved. 200-300 ms instead of standard 80-120 miss
• 🔹 Noise reduction functions (ANC) or the transparent system is not working properly
• 🔹 Automatic reconnection after switching off the headphones does not always work

Fortunately, most of these problems are solved manually, as detailed in the following sections, and in the meantime, we'll go through the basic pairing algorithm.

Preparing for connection: 5 mandatory steps

Before you click “Connect”, do these steps – they will save you 20-30 minutes to fix typical errors:

Update the headphone firmware through Huawei AI Life|Turn off headphones from all previous devices|Turn on Bluetooth on your smartphone and activate detection mode|Check the charge of the headphones (minimum 30%)|Reboot your smartphone if you’ve had Bluetooth failures before-->

Critically, if your FreeBuds were previously connected to a device on Huawei’s EMUI, they may “remember” the profile and refuse to work with MIUI.

1. Place the headphones in the case and close the lid.
2. Press and hold the button on the case for 10-15 seconds until the indicator starts flashing red and white (reset mode).
3. After reset, try again to connect to Xiaomi.

On Xiaomi smartphones with MIUI 13/14, it is also recommended to disable the dual Bluetooth connection function (Settings → Bluetooth → Additional), as it can cause conflicts with Huawei headphones.

Step-by-step: how to connect Huawei FreeBuds to Xiaomi

Follow this algorithm – it works for all FreeBuds models (except FreeBuds Lipstick, they need a separate method):

1. Activate the pairing mode on the headphones: 🎧 For FreeBuds 3/4/5: open the case cover, press and hold the button on the back panel 3 seconds until the indicator starts flashing white. 🎧 For FreeBuds Pro/Pro 2: open the case, press the touch panel on both headphones at the same time on the 5 seconds.
2. On a Xiaomi smartphone: 📱 Go to Settings. → Bluetooth. 📱 Turn on Bluetooth and tap Add the device. 📱 In the list, find your FreeBuds (the name will contain the model, for example). HUAWEI FreeBuds 5). 📱 Then click on them and confirm the link.

Confirm the connection.

• ✅ The headphones should sound the voice signal "Connected" (or similar in Chinese for older models).
• ✅ In the list of Bluetooth devices will appear status "Connected".

Important for FreeBuds Pro 2: if no noise reduction is working after you connect, go to Bluetooth Settings → Device Settings → Sound Quality and manually select the AAC codec over SBC.

💡

If the headphones aren't being identified, try connecting them to another device (like a laptop) and then back to Xiaomi.This often resets "hangy" Bluetooth profiles.

Problem Solving: Headphones are connected but not working

The situation where FreeBuds are displayed as connected, but the sound is through the speaker of the smartphone or not at all, is typical for MIUI.

For FreeBuds Pro 2 and later, also check the settings in the Huawei AI Life app (if installed), which sometimes resets the noise reduction settings after connecting to MIUI.

⚠️ Note: If after the update MIUI The headphones stopped connecting, try rolling back the Bluetooth stack version. → About the phone tap 5 times on the version MIUI, Then select Additional settings. → Bluetooth rollback (not available on all models).

Optimizing Sound: How to Improve Quality on Xiaomi

Even after a successful connection, the sound can be frustrating - especially if you're used to Huawei's "native" ecosystem.

• 🎛️ Enable Mi Sound Enhancer: Go to Settings → Sound. → Sound quality. Activate Sound Improvement slider and select Bassy preset.+ or Jazz (for vocals).
• 🔊 Set up the equalizer: In the same menu, select the equalizer and create a custom profile with a rise to the top. 60-100 Hz (for bass) and 3-6 kHz (for vocals).
• 📶 Turn off Absolute Volume: In Settings → Bluetooth → Deactivate the option Absolute Volume – this will remove the volume restrictions.

FreeBuds Pro 2 and FreeBuds 5 also have an LDAC setting (if the smartphone supports it) to activate:

Settings → Bluetooth → Device settings → Sound quality → LDAC (990 kbps)

Warning: LDAC It can cause stuttering on weak processors (such as the Redmi Note 10). AAC.

Model Compatibility: Which Huawei FreeBuds Works Best With Xiaomi

Not all Huawei headphones work equally well with MIUI, and we tested 8 models and ranked them for connectivity and sound quality.

If you’re just planning a purchase, look for FreeBuds Pro 2 or FreeBuds 5 — they support AAC and aptX, which is critical for compatibility with Xiaomi. Models older than 2020 (FreeBuds 3, FreeBuds Lite) often only work via SBC, which noticeably degrades the sound.

⚠️ Huawei FreeBuds Lipstick headphones require mandatory installation of the Huawei app AI Life is working with MIUI. Without it, they will connect, but will not correctly display the charge level and control gestures.

Alternative ways to connect (if Bluetooth is not working)

If standard pairing fails, try these methods:

• 🔌 Through the Huawei app AI Life: Download the app from AppGallery or APKPure. Register (you can use Huawei) ID In the Devices section, select Add Add → Headphones and follow instructions.

Resetting the network on Xiaomi

1. Go to Settings. → SIM-maps and networks → Resetting the network.
2. Select Reset Wi-Fi, Mobile Network and Bluetooth settings.
3. After restarting, reconnect.

For advanced users, the way is also available via ADB (requires an unlocked bootloader on Xiaomi):

adb shell settings put global bluetooth_audio_codec aac


adb shell settings put global bluetooth_audio_sample_rate 44100




adb shell settings put global bluetooth_audio_bits_per_sample 16

These commands force the AAC codec to be installed at 256 kbps, which improves sound for most FreeBuds models.

💡

If the headphones are plugged in but permanently shut down, the problem is MIUI power saving. Turn off Bluetooth battery optimization in Settings → Applications → Battery Management → Battery Optimization (find Bluetooth in the list and select Without Limits).
