Connecting Bluetooth speakers to Xiaomi phone: from pairing to fine-tuning the sound

Why your Xiaomi might not see the column – and how to fix it

Wireless speakers have become an integral part of everyday life, from listening to music in the shower to organizing mini-party in nature. However, owners of Xiaomi smartphones (including sub-brands Redmi and POCO) often face unexpected problems when trying to connect an audio device via Bluetooth. The phone does not find the speaker, the connection is constantly breaking, the sound is interrupted every 10 seconds. In this article, we will examine not only the basic pairing, but also the hidden settings of MIUI that affect the stability of the Bluetooth connection – they are ignored even in official instructions.

It’s important to understand that the connection algorithm may differ depending on the version of MIUI (12, 13, 14 or HyperOS) and the speaker model. For example, the JBL Charge 5 requires a separate reset procedure before first pairing, and the Xiaomi Mi Portable Speaker automatically goes into search mode when turned on. We’ll look at universal steps as well as nuances for popular brands – from budget Tronsmart to premium Bose.

Preparation: What to check before connecting

Before you click on the Device Search button, make sure your smartphone and speaker are paired, and neglecting these steps leads to 70% of connectivity issues (Xiaomi service centers data for 2023).

• 🔋 Battery charge: The column must be charged at least 30%.Some models (e.g. Sony) SRS-XB43) Turn off the Bluetooth module at low charge.
• 📱 Version. MIUI: Update the firmware through Settings → The phone. → Update of the system in older versions (below) MIUI 12.5) no codec support LC3 and AAC, scalp.
• 🔄 Network Reset: If you have previously had problems with Bluetooth, reset to Settings → Connections and sharing → Resetting network settings.
• 🎵 Column Mode: Make sure the device is in pairing mode (usually flashing blue/red indicator).For Xiaomi Mi Smart Speaker, hold the power button for 5 seconds.

Xiaomi smartphones with Snapdragon 8 Gen 2 processors (such as Xiaomi 13 Pro) support aptX Adaptive and LDAC, which significantly improves sound quality. To check the available codecs:

1. Activate Developer Mode (7 times click on the MIUI version in your phone settings).
2. Go to Settings → Additional → Developer Settings → Bluetooth Settings.
3. Select the priority codec (recommend AAC for balance of quality and stability).

Step-by-step: how to connect the column to Xiaomi via Bluetooth

Now, to the interface process itself, follow the instructions carefully, and skipping even one step can lead to the "I couldn't connect" error.

1. Turn on Bluetooth on your phone: Swipe down the screen to open the notification bar, and click on the Bluetooth icon. Or go to Settings → Connections and Sharing → Bluetooth.
2. Activate Column Search Mode: For JBL: Hold the Bluetooth button for 3 seconds until the light flashes. For Xiaomi Mi Portable Speaker, turn the device on and it will automatically pair. For Sony, press and hold the power button until you hear the beep.

Find the column in the list of devices

"JBL Flip 6"

"Mi Smart Speaker"

Confirm the conjugation

If the column doesn’t appear in the list, try the following:

Make sure that the column is in pairing mode (blinking indicator)

Reboot Bluetooth on your phone (turn off/on)

Remove the column from the list of associated devices (if previously connected)

Update the column firmware (for models with support) OTA-update)-->

After a successful connection, check the sound quality. If you hear interference or delays, go to Bluetooth Settings → Sound settings and select the AAC or SBC codec (for stability).

💡

If the speaker is connected but the sound is coming through the phone speaker, check the media device settings in the notification panel. Sometimes MIUI automatically switches the audio output to the phone after the call.

Common mistakes and their solutions

Even after successful pairing, users face typical problems, and we’ve compiled the most common bugs and fixes based on Xiaomi technical support data and feedback from 4PDA forums.

Note the features of MIUI 14 and HyperOS: these firmware versions add Bluetooth Auto Switch, which automatically switches audio devices depending on scenarios. For example, if you listen to music through a speaker and start a conversation on the phone, the sound can switch to the smartphone speaker to turn off this feature:

1. Go to Settings → Connections and Sharing → Bluetooth.
2. Click on the icon. ⚙️ next to the connected column.
3. Turn off the option "Automatic switching of audio devices".

Sound Optimization: How to Improve the Quality of Playback

Connecting a speaker is only half the battle, and to get really good sound, you have to adjust a few settings on the phone and on the speaker itself, especially for models that support aptX or LDAC, where the wrong settings can negate all the benefits of high-quality codecs.

Let’s start with the uniformity settings (EQ) in MIUI:

1. Open the Music app (or any other player, such as Poweramp).
2. During playback, click on the icon. ⚙️ or "Effects".
3. Select a preset profile (Bas, Rock, Jazz) or set up your EQ manually.

For speakers with LDAC support (for example, Sony WH-1000XM5 or Xiaomi FlipBuds Pro) we recommend:

• 🎛️ Set the bitrate of 990 kbit / s (maximum quality) in the Bluetooth codec settings.
• 📶 Turn off Wi-Fi during listening to avoid interference.
• 🔋 Keep track of the column charge at a level below 20% MIUI Automatically reduces bitrate to save energy.

If you use a movie speaker, turn on Low Latency in your Bluetooth settings. This will reduce the lag between video and sound, which is critical for dynamic scenes. On some Xiaomi models (such as the Redmi Note 12 Pro+), this mode is activated automatically when you start the video player.

💡

For better sound, turn off the MIUI audio processing: go to Settings → Sound and Vibration → Sound Effects and deactivate the Sound Improvement option. This feature often distorts high frequencies.

Connecting two speakers at the same time (Dual Audio)

One of the hidden features of MIUI is the ability to connect two Bluetooth speakers simultaneously to create a stereo effect or increase volume, but this feature does not work on all models and requires certain conditions:

• 📱 Supported devices: Xiaomi 11/12/13 series, Redmi K50 Pro, POCO F4 GT newer.
• 🔊 Compatible columns: both must support the protocol A2DP 1.3 (Most modern models).
• 🔋 Battery charge: Both columns must be charged at least 50 times%.

To activate Dual Audio:

1. Connect the first column in the standard way.
2. Insert the second column in the pairing mode.
3. Go to Settings → Connections and Sharing → Bluetooth.
4. Click on the icon. ⚙️ next to the first column and select "Add a second device".
5. Select the second column from the list.

Once connected, you can adjust the balance between the speakers or create a stereo effect (left/right).

1. Open the notification bar and hold the Bluetooth icon.
2. Press "Sound settings" → "Dual Audio".
3. Select the mode: "Stereo" or "Duplicate sound".

Problems with specific column models

Some Bluetooth speakers have unique features of pairing with Xiaomi, and we have collected the most problematic models and solutions for them:

For Xiaomi speakers (such as Mi Portable Bluetooth Speaker or Mi Smart Speaker), the branded “Mi Home” app is available, which allows you to update the device’s firmware and configure additional settings, such as:

• 🎚️ Equator with presets for different genres of music.
• 🔄 Automatic shutdown in case of inactivity (timer) 5-60 minute).
• 🔋 Energy saving mode, which extends the operating time to 20 hours.

If you use a speaker for calls (e.g. JBL Live 660NC), make sure that the Bluetooth settings activate the "Use for calls" option, otherwise the speaker microphone will not work and the person will not hear you.

💡

For speakers with support for aptX Low Latency (for example, Audio-Technica ATH-SR30BT) in MIUI 14+, a special mode is available "Game Sound", which reduces latency to 40 ms.
