What to do if Xiaomi phone does not connect to headphones via Bluetooth: the full guide

Are you trying to connect wireless headphones to a Xiaomi smartphone, but the devices are persistently unable to see each other? Or is the connection constantly breaking after a few seconds? Bluetooth problems on Redmi, POCO or Mi phones are one of the most common complaints of users. The reasons can be rooted in software failures and hardware malfunctions. In this article, we will analyze all possible scenarios, from basic checks to hidden MIUI settings that will help restore communication.

It’s important to understand that the solution algorithm depends on the headphone model and the firmware version. For example, Xiaomi Buds 4 Pro can conflict with MIUI 14 due to driver errors, and old Redmi AirDots sometimes require manual reset. We have collected current methods for devices in 2020-2026, including Redmi Note 12, POCO X5 and Mi 11. If after all the manipulations the problem remains, at the end of the article you will find a checklist for hardware malfunctions.

Basic diagnostics: check headphones and phone

Before digging into MIUI settings, make sure the problem isn't in the trivial stuff. Start by checking the headphone charge: most Xiaomi models (like the Buds 3T Pro or Air 2SE) turn off the Bluetooth module when it's below 5%. Connect them to the charging case for 10-15 minutes and try again.

Next, check the physical condition of the devices:

• 🔋 Headphones: check if the indicator on the case is on (should flash white/blue when searching). If the indication is missing, the case battery may have gone down or the contact has gone off.
• 📱 Phone: Make sure Bluetooth is enabled not only in the notification curtain, but also in settings (Settings) → Connections → Bluetooth. Sometimes crashes MIUI Reset the module to "off" after rebooting.
• 🔄 Reboot: Turn off and re-enable both devices. This will reset temporary connection errors.

Critical: If the headphones have previously connected to another phone (like an iPhone), they can stay in the memory of that device and ignore new requests, in which case you need to reset the headphones — more about this in the next section.

2. Resetting headphones and cleaning the list of associated devices

If Xiaomi headphones have previously connected to other gadgets, they may "forget" your phone or conflict with it.

After resetting the headphones, be sure to clean the list of conjugated devices on the phone:

1. Open Settings → Connections → Bluetooth.
2. Find your headphones in the list and click on the gear. ⚙️ near-name.
3. Choose to Remove this device (or Forget it).
4. Reboot the phone.

Bluetooth settings in MIUI: hidden settings

MIUI hides a number of useful features for Bluetooth diagnostics, such as new firmware versions (starting with MIUI 13) adding a compatibility mode that helps connect devices with outdated protocols to activate it:

1. Go to Settings. → The phone.
2. Click 7 times on the MIUI version to enable the developer mode.
3. Back to Settings → Additionally. → For developers.
4. Find the option to Enable Bluetooth compatibility and activate it.

If the headphones are plugged in but the sound is interrupted or distorted, try changing the Bluetooth codec:

• 🎧 B Settings → Sound. → Bluetooth Sound Quality Select SBC (most compatible codec).
• 🔊 If the sound is too quiet, activate Absolute Volume in the developer settings.

On some models (Redmi Note 11, POCO X3 Pro) it helps to disable the dual Bluetooth connection function (located in Settings → Connections → Bluetooth → Additional).

4. Update of firmware and Bluetooth drivers

Connection errors are often caused by outdated Bluetooth module drivers. Xiaomi regularly releases patches to fix such bugs, so the first thing to do is update the firmware:

1. Open Settings → About the phone → System update.
2. Click Check Updates and install the latest version of MIUI.
3. After the update, restart the phone.

If there are no updates but the problem remains, try manually reinstalling the Bluetooth driver:

1. Download the Mi Bluetooth app from AppGallery (it contains current profiles for Xiaomi headphones).
2. Install the app and start scanning the devices.
3. Follow the instructions on the screen to re-pair.

💡

If after the MIUI update, the headphones stopped connecting, try rolling back to the previous firmware version via Settings → About Phone → System Update → Three dots (menu) → Select an update package. Download the old firmware from the official Xiaomi website and install it manually.

For Android 12+ devices (such as Xiaomi 12T or Redmi K50), resetting your network settings can help:

1. Go to Settings → Connections → Additional → Reset network settings.
2. Confirm the action (this will remove all stored Wi-Fi and Bluetooth devices).
3. Restart your phone and try to connect again.

5. Conflicts with other devices and applications

Sometimes Bluetooth on Xiaomi refuses to work due to background processes or conflicts with other gadgets.

• 📱 Other connected devices: If your phone already has a smartwatch (Mi Band), speaker, or car radio, turn them off. MIUI Limits the number of simultaneous Bluetooth connections (usually up to 2-3 devices).
• 🔒 VPN Firewalls: Some applications (e.g. NordVPN or Avast) block Bluetooth traffic.
• 🎵 Music apps: Spotify, YouTube Music or MIUI Music can take over an audio channel. Close them through recent apps.

Pay special attention to the power saving mode. MIUI has a Background Limitation feature that can turn off the Bluetooth module to save charge:

1. Open the settings → Battery → Power saving mode.
2. Select No Limits or add Bluetooth to the exclusion list.

💡

If the headphones are connected, but the sound goes through the speaker of the phone – check the audio output settings in the application that plays the audio (for example, in YouTube, click on the speaker icon and select headphones).

6. Hardware malfunctions: when to contact the service

If none of the software methods worked, the problem could be in the hardware.

• 🔌 Bluetooth does not turn on at all: the icon in the notification curtain is inactive, and an error appears in the settings.
• 🔍 The phone doesn’t see any device: even other smartphones or speakers aren’t identified when searching.
• 🔥 Overheating of the case: If the area near the camera or the top of the phone gets very hot when trying to turn on Bluetooth, it may indicate chip damage.

In such cases, you will need a diagnosis in the service center: the average cost of repairing a Bluetooth module on Xiaomi (2026):

⚠️ WARNING: If the phone fell or got wet before the problem appeared, don't try to disassemble it yourself! Xiaomi uses glue to fix the plumes, and careless intervention can damage other components. The service will check the integrity of the contacts and, if necessary, will conduct ultrasonic cleaning of the board from corrosion.

7. Alternative ways to connect headphones

If Bluetooth never worked, but the headphones support other protocols, you can try workarounds:

• 🎧 Wired Connection Mode: Some models (Xiaomi Buds 3 Pro) support connectivity via USB-C-cable (needs adapter) USB-C → The sound will be transmitted over the wire and the microphone will continue to work on Bluetooth.
• 📡 Bluetooth Transmitter: Buy an external adapter (e.g. Baseus) B07) and connect it to the phone through USB-C. This will bypass the faulty built-in module.
• 🔊 Using a single headphone: if the problem is only with mono connectivity, try connecting the headphones separately (for example, only the right one).

For owners of POCO F3 or Xiaomi 11 Lite, there is another life hack: activate developer mode and enable Bluetooth Debugging, which sometimes helps bypass MIUI restrictions on connecting uncertified devices.
