Why Xiaomi doesn’t see Bluetooth headphones: A complete guide to diagnostics and repair

You're trying to connect wireless headphones to a Xiaomi smartphone, but the device stubbornly "can't see" them? The problem is found on both the budget Redmi and the flagship Mi 13 Ultra — and there can be a dozen reasons, from a banal Bluetooth module failure to hardware malfunctions. In this article, we will analyze all possible scenarios why Xiaomi does not detect headphones, and give step-by-step instructions for each case, from reboot to reflash.

Important: if your headphones previously worked with another device, but suddenly ceased to be determined by Xiaomi, the problem with 90% probability lies in the settings of the smartphone. If the headphones are new and did not mate with anything, check their compatibility with Bluetooth protocols (more about this in the section on hardware limitations).

We won’t offer “magic” solutions like “reset your phone” without explanation — each paragraph of the article contains a technical rationale and alternative methods if the main one didn’t work. At the end, you will find an FAQ with answers to the most common questions, including problems with specific headphone models (AirDots, Sony WH-1000XM5, JBL, etc.).

1. Check basic Bluetooth settings on Xiaomi

So, start with the obvious: maybe the problem isn't with the headphones, but with the smartphone settings that aren't right, and even if you're sure it's all on, go through this checklist, and sometimes the settings get lost after the MIUI update.

Make sure Bluetooth is turned on in the notification curtain

Check that Invisible to Other Devices mode is disabled in the settings

Turn off the power saving mode (it can block device search)

Remove headphones from the list of paired devices (if there are any)

Reboot your smartphone (hold the power button for 10 seconds to completely shut down)-->

Pay special attention to the energy saving mode item: in MIUI 14+, it defaults to limit the operation of the Bluetooth module to save charge.

  1. Go to Settings → Battery and performance → Energy saving mode.
  2. Select “No Limits” or add the Bluetooth app to exceptions.
  3. Also check the settings of a particular app (such as Mi Music or Spotify) if the headphones connect through it.

If after these manipulations, the headphones are still not detected, move to the next section - the problem may be deeper.

Reset Bluetooth settings: when and how to do

If the basic settings didn't work, the next step is to completely reset the Bluetooth module, which will remove all the paired devices and return the settings to the factory settings, and the procedure is safe and does not affect other data on the smartphone.

How to reset Bluetooth to Xiaomi:

  1. Open Settings → Connections and Sharing → Bluetooth.
  2. Tap the three-point menu (⋮) in the upper right corner and select Reset settings».
  3. Confirm action. The smartphone will reboot automatically.

After you restart, try reconnecting your headphones. If they still don't show up, check:

  • 🔍 Headphone visibility: Many models (e.g. Xiaomi AirDots Pro 2) require holding the 5 button+ seconds to switch to mating mode.
  • 📱 Protocol compatibility: Old Bluetooth 4.0 headphones may not work with new Bluetooth 5.2 smartphones+.
  • 🔄 Firmware update: in MIUI Patches are often released to fix Bluetooth problems (more on this in Section 5).

💡

If your Bluetooth headphones are connected after resetting, but the sound is interrupted, turn off the Absolute Volume option in your audio settings, which can cause conflicts with some headphone models.

3. Hardware problems: when the smartphone itself is to blame

If the software methods don’t work, the problem may lie in the physical malfunction of the Bluetooth module or antenna.

  • 💥 Falling from a height (especially to the corner where the module is located).
  • 🌊 Contacted with moisture (even if the phone is waterproof - contact corrosion is possible).
  • 🔧 Disassembled for repair (insecure connection of the antenna plume).

How to check the hardware serviceability:

  1. Connect another Bluetooth device (like a smartwatch or a speaker) to your smartphone, and if it's not detected, it's the phone.
  2. Try connecting your headphones to another phone, and if they work, it's your Xiaomi fault.
  3. Check if the top of the smartphone is overheating (the Bluetooth module is usually located there), and overheating may indicate a short circuit.

If the suspicion of hardware malfunction was confirmed, there are two options:

  1. Contact the service center (especially if the phone is warranty) and repair of the Bluetooth module will cost 1,500-4000 ₽ model-wise.
  2. Using an external Bluetooth adapter (via USB-C or 3.5mm connector if you have one) is a temporary solution, but will allow you to use headphones.
What does a damaged Bluetooth module look like?
The photos below show typical module damage after a drop or moisture hit: 1. Antenna detachment – thin tracks on the board can move away from the contacts. 2. Corrosion – green plaque on the legs of the chip (even if the phone did not sink, moisture could penetrate through the microphone or speaker). 3. Cracks on the board – often invisible to the naked eye, but cause interruptions to the signal. Note: Self-repair without a solder station and experience can completely break the phone.

4.Firmware and MIUI conflicts: how an update can break Bluetooth

One of the most common reasons Xiaomi stops seeing headphones is because of bugs in the firmware, especially for:

  • 📱 Smartphones on MIUI 13/14 Global firmware (often updated later than the Chinese version, and bugs remain unfixed longer).
  • 🔄 Devices after manual downgrading (downgrading version) MIUI).
  • 🛠 Phones with custom firmware (for example, LineageOS or Pixel Experience).

How to check if the firmware is to blame:

Symptoms.Probable causeDecision
Bluetooth is turned on but does not find devicesFailure in the Bluetooth HAL stackUpdate MIUI or roll back to a stable version
The headphones are connected, but the sound is interrupted.Bug in the audio codec driver (often after an update)Reset the sound settings or disable LDAC/aptX
Bluetooth shuts down on its ownConflict with the MIUI energy saving modeAdd Bluetooth to Optimization Exceptions
The headphones are only connected after restarting.Memory leak in the service bluetoothdClear the cache of system applications

If you suspect that the problem is in the firmware, follow the following steps:

  1. Check out the current version of MIUI in Settings → About Phone. Compare it to the latest stable builds on en.miui.com.
  2. If an update is available, install it. If the problem has occurred after the update, try rolling back to the previous version via Fastboot.
  3. For experienced users: install EU-Firmware (unofficial European assembly) MIUI). It is often devoid of global version bugs.

💡

After the update MIUI Bluetooth stopped working at all (it does not even turn on in the settings), this is a sign of the “flying” driver. EDL-Mode (requires an authorized Xiaomi account).

5.Earphone problems: why they can be 'invisible'

It's not always the smartphone that's to blame -- the headphones themselves can be the source of the problem, too.

  • 🔋 Battery discharged: many models (for example, Xiaomi Air 2) SE) They do not signal mating if the charge is below 5%.
  • 🔄 Failure of the firmware of headphones: especially important for cheap clones of AirPods or headphones with AliExpress.
  • 🎧 Hardware malfunction: damage to the antenna or Bluetooth chip inside the headphones.
  • 📦 Protocol incompatibility: for example, headphones with Bluetooth 4.1 may not work with Xiaomi 13 Pro on Bluetooth 5.3.

How to diagnose the problem:

  1. Try connecting your headphones to another device (laptop, tablet, second phone) if they aren't detected anywhere, the problem is with them.
  2. Check the headphone indicators: 🔴 Red flashing - discharged or in mating mode. 🔵 Blue flashing - ready to connect. 🟢 Green Permanent – already connected to another device.

For Xiaomi/AirDots headphones, reset them to factory settings. To do this, hold both touch panels for 15 seconds until the red light flashes twice.

If the headphones are new and never connected, check their compatibility with the codec. For example, the Sony WH-1000XM5 defaults to LDAC, which can conflict with older Xiaomi smartphones.

  1. In Bluetooth settings on your smartphone, turn off LDAC/aptX and select SBC or AAC.
  2. Update the firmware of the headphones through the official manufacturer’s app (for example, Sony Headphones Connect).

How to reduce the impact of interference:

  1. Move to another location (e.g. kitchen to room if microwave is nearby).
  2. Turn off Wi-Fi on your smartphone and try to connect headphones - sometimes channels conflict.
  3. If you use Xiaomi in your car, try connecting your headphones before starting the engine – some car systems cause interference.
  4. For routers: Change the Wi-Fi channel in settings (e.g., from 6 to 11).

Also check if your smartphone is running Bluetooth enabled, which in some versions of MIUI blocks new device searches despite Bluetooth enabled.

How do you check the load of the air?
Download the WiFi Analyzer app (available on Google Play) to show which 2.4GHz channels are busy in your environment. If the channel your headphones are running is overloaded (e.g., using 5+ devices), try connecting elsewhere or wait for a lesser load (evening/night).

7. Radical methods: factory reset and flashing

If none of the previous methods worked, the following are the extreme measures:

  1. This will delete all data from the phone, but often solves Bluetooth problems caused by conflicts in system files.
  2. Fastboot flashing. It's relevant if the crash happened after the MIUI update.
  3. Replacement of Bluetooth module. Last option if confirmed hardware malfunction.

How to reset Xiaomi to factory settings:

  1. Make a backup of the data through Settings → About Phone → Backup.
  2. Go to Settings → Additional → Recovery and Reset → Resetting.
  3. Select "Erase Everything" and confirm the action. The phone will reboot.

If the reset didn't work, try to reflash your phone through Fastboot.

  1. Download the official firmware for your model from en.miui.com.
  2. Install the Mi Flash Tool on your PC and connect your phone in Fastboot mode (clip Volume Down + Power when your phone is off).
  3. Follow the instructions in the firmware program.

⚠️ Note: Fastboot flashing erases all data, including photos and apps. If the phone is warranted, this method can cancel it. 12T, Redmi Note 12 and later will require unlocking via Mi Unlock Tool, which will take 7-30 days to wait.
