Connecting a wireless headset to Xiaomi Redmi: instruction + error solving

Wireless headphones have become an integral part of everyday life – they are convenient for listening to music, calling and even watching videos. Owners of Xiaomi Redmi smartphones (Note 12 series, POCO X5, Redmi A2 and others) often face questions: how to connect the headset correctly over Bluetooth, why the device does not find headphones or the sound is interrupted? In this article, we will analyze not only the basic steps of pairing, but also the nuances of working with different models of headsets (AirDots, Sony WH-1000XM5, JBL Tune), as well as typical errors that interfere with stable communication.

It is important to understand that the connection process may vary depending on the version of MIUI (e.g. MIUI 14 vs MIUI 12.5) and the type of headset. For example, headphones with support for LE Audio (like Xiaomi Buds 4 Pro) require a special approach, and older models may need to reset before the first connection. We will also touch on the issues of Bluetooth codecs (AAC, aptX, LDAC) and their impact on sound quality – this is relevant for music fans who want to get the most from their headset.

1. Preparation of the smartphone and headset for connection

Before you start pairing, make sure both devices are ready to go. Let's start with your smartphone.

• 📱 Update: Go to Settings → The phone. → Update the system and install the latest patches, which is important because newer versions MIUI Bluetooth errors are corrected.
• 🔋 Charging: Make sure the headset has a charge level of at least 30%.Some models (e.g. Xiaomi AirDots 3 Pro) refuse to turn on when the charge is low.
• 🔄 Reset: If the headset has already been connected to another device, reset (usually by pressing the power button for 10-15 seconds before the indicator flashes).

Pay special attention to the power saving mode. In Xiaomi Redmi, it can restrict Bluetooth, which leads to communication interruptions, to turn off the restrictions:

1. Open Settings → Battery and Performance.
2. Select Power Saving Mode → Settings.
3. Find Bluetooth and remove the restrictions.

💡

If your headset supports a companion app (such as Xiaomi Earbuds or JBL Headphones), install it ASAP. This will help you set up the equalizer and update the headphone firmware.

2. Step-by-step connection instruction

Now, let’s get to the interface process itself, and consider the universal algorithm that is suitable for most Redmi models (including the Redmi Note 11 Pro+, POCO F4, and others):

1. Activate Bluetooth on your smartphone: Swipe down from the top edge of the screen to open the notification bar. Press and hold the Bluetooth icon (or go to Settings → Connections → Bluetooth). Turn the switch on to the "On" position.
2. Put the headset in pairing mode: For most models: press the power button for 3-5 seconds until the indicator starts flashing blue and red (AirDots) or white (Sony). For Xiaomi Buds 4 Pro: open the case cover and press the button on the back for 10 seconds.

Find the device in the list

• On the smartphone in the Bluetooth menu will appear the name of your headset (for example, LE_Buds4Pro_R or WH-1000XM5).
• Then, click on it and confirm the link (if necessary).

The headset appears in the list of "Connected devices"|The indicator on the headphones is lit with even light (does not flash)|The sound is played through headphones (check in the player)|The microphone is working (record the voice message)-->

If the headset doesn’t appear on the list, try the following:

• 🔄 Reboot Bluetooth Module: Disconnect and Re-enable Bluetooth on Smartphone.
• 📴 Reboot your smartphone: Sometimes a basic reboot helps, especially if there have been crashes before.
• 🔌 Check codec compatibility: In Bluetooth Settings → Additionally. → Select audio codec AAC (Universal) or aptX (for high quality).

3. Customization of sound and microphone after connection

Once paired successfully, it is important to adjust the sound settings correctly to avoid problems with the playback quality or microphone.

• 🎧 Selecting Output Device: While playing music or video, swipe down the notification panel and make sure your headphones are chosen as the output device, not the smartphone speaker.
• 🎚️ Equator: Go to Settings → Sound. → Equalizer and select the appropriate preset (e.g. Bass or Rock). MIUI 14 Dolby Atmos Mode available - turn it on for surround sound.
• 🎤 Microphone: If the interlocutor does not hear you during calls, check the microphone settings in Settings → Annexes → Phone. → Permits (Micphone use should be allowed).

For headsets with noise reduction (ANC) or transparent mode (for example, Xiaomi Buds 4 Pro or Sony WH-1000XM5), additional options are available:

4. Solving common problems

Even after a successful connection, Xiaomi Redmi users may face typical problems, including the most common ones and ways to fix them:

⚠️ Note: If the headset is connected, but the sound is interrupted every 5-10 seconds, the problem may be in conflict with Wi-Fi. Bluetooth and Wi-Fi in Xiaomi smartphones work on the same frequency (2.4 GHz.

4.1 Headset plugs in, but no sound

Causes and solutions:

• 🔈 Incorrect output device: Check that the notification panel selected headphones, not the speaker.
• 🔊 Disabled sound in headphones: On some models (for example, JBL Tune 510BT) There is a separate volume button – make sure the sound is not at a minimum.
• 🔄 Reset Bluetooth settings: Go to Settings → System system → Resetting settings → Reset network settings (this will delete all saved devices).

Permanent communication interruptions

If communication is interrupted while driving or at a distance of more than 5 meters:

• 📶 Interference: Make sure there are no running microwaves, Wi-Fi routers, or other sources of interference.
• 🔋 Low headset charge: Some models start to "glutch" when charged below 20%.
• 🛠️ Firmware Update: Check for headset updates through a proprietary app (e.g. Xiaomi Earbuds).

💡

If the problem with communication breaks occurs only in the subway or elevator, it is not the smartphone that is to blame, but the shielding of the signal with metal surfaces, in which case only changing the headset to a model that supports Bluetooth 5.2+ and LE Audio will help.

5. Features of connection to different models of Redmi

The pairing process may vary slightly depending on the smartphone model and the version of MIUI. Let’s consider the key nuances:

5.1. Redmi Note 12/13 and POCO X5 (MIUI 14)

These models feature “Fast Pair” which makes it easier to pair with supported devices (e.g. Xiaomi Buds 4 Pro):

1. Open the case cover with headphones.
2. On the screen of the smartphone will appear a pop-up window with a suggestion to connect.
3. Click Connect and follow the instructions.

MIUI 14 also adds LE Audio support to improve sound quality and reduce energy consumption.

Settings → Connections → Bluetooth → Settings (cogs) → Enable LE Audio

Redmi A2 and budget models

Budget smartphones (such as the Redmi A2) may not support modern codecs (aptX, LDAC).

• Use the AAC or SBC codec.
• Turn off noise reduction functions if they cause delays.
• Update your firmware to the latest version – new MIUI builds sometimes add support for additional codecs.

6. Safety and optimization of work

Connecting wireless devices is always fraught with security risks, and here are some tips on how to protect your data:

• 🔒 Turn off Bluetooth when not in use: This will prevent unauthorized intruders from connecting.
• 📱 Use Invisibility Mode: In Bluetooth settings (Settings) → Connections → Bluetooth → Additionally) enable the option to Hide the device.
• 🔄 Regularly update the software: in new versions MIUI Bluetooth-related vulnerabilities are closed.

To optimize the work of the headset:

• 🔋 Turn off automatic Wi-Fi connection in subway/transport: This will reduce the load on the Bluetooth module.
• 🎵 Close background apps that use a microphone (like voice assistants) if they are not needed.
• 📴 Reboot your smartphone every 2-3 days: This clears the cache of the Bluetooth module.

⚠️ Note: If you connect a headset to Xiaomi Redmi in a public place (cafe, airport), disable the Auto Connection feature in Bluetooth settings. This will prevent accidental connection to other devices with the same name.

7. Alternative ways of connecting

If standard Bluetooth connection does not work, you can use alternative methods:

Connection through a companion application

Some headsets (such as Sony WH-1000XM5 or JBL Live 660NC) require the installation of a proprietary application to work properly.

1. Download the app from Google Play (like Sony Headphones Connect or JBL Headphones).
2. Follow the instructions in the pairing app.
3. Configure additional functions (equalizer, noise reduction) through the application interface.

Use of Bluetooth adapter (for older models)

If your Redmi does not support modern Bluetooth protocols (for example, you have Redmi 4X with Bluetooth 4.2), you can use an external Bluetooth 5.0 adapter with a USB-C connector.

1. Buy an adapter with aptX LL support (for low latency).
2. Connect it to your smartphone through OTG-cable.
3. Turn the headset into pairing mode and connect to the adapter.

💡

For multipoint headsets (connecting to 2 devices at the same time), connect them to a Redmi first, and then to a second device (like a laptop), which allows you to quickly switch between sound sources.
