Why Xiaomi Headphones Are Separating: 7 Main Reasons

Before we get to the synchronization instructions, it's worth looking at why the headphones stop working together, and most often, the problem is software failures or misuse.

• 🔋 A discharged battery in one of the headphones (even if the indicator shows charge, contact may be disrupted).
• 📱 Failure of firmware after updating or incorrect disconnection from the smartphone.
• 🔄 Automatic pair reset when connected to a new device (especially relevant for Redmi AirDots 3 Pro).
• 🎧 Mechanical damage to contacts in the case or on the headphones themselves.
• 📶 Interference from other Bluetooth devices (for example, if wireless speakers or headphones are working nearby).
• 🔧 Incorrect removal from the case (if you take out the headphones at the same time, they may not synchronize).
• 🛠️ Hardware defect (less often, but possible when falling or moisture is ingested).

If the headphones disconnected after the firmware update, the problem may lie in the incompatibility of the new version of the software with your model, in which case a rollback to the previous version or forced flashing through the PC will help.

⚠️ Note: If Xiaomi headphones disconnect after contact with water or falling, do not try to sync them yourself. This can lead to a short circuit.

Method 1: Standard case synchronization (for most models)

It's the simplest and most versatile method that works for Redmi AirDots, Mi True Wireless and other models with a charging case.

1. Place both headphones in the case and close the lid.
2. Wait 10-15 seconds – during this time, the headphones should automatically sync.
3. Get your headphones out of the case at the same time (this is important!).
4. Wait for the audible signal of the connection (usually a voice message or a melody).

If the headphones still don’t work together after that, try forcibly restarting them:

• 🔄 Press and hold the touchpad on both headphones for 10-15 seconds.
• 🔴 Wait until the indicators start flashing red (meaning the headphones have reset the connection).
• 🟢 Place the headphones back in the case and repeat the synchronization procedure.

Method 2: Resetting Xiaomi headphones to factory

If standard synchronization doesn't work, the next step is to completely reset the settings, which will remove all the saved connections and return the headphones to their original state. The instructions are suitable for most models, but for some (for example, Xiaomi Buds 4 Pro) there may be nuances.

How to reset your settings:

1. Place both headphones in the case and close the lid.
2. Open the cover and hold the button on the case (if any) for 10-20 seconds until the indicator flashes red and white.
3. For models without a button on the case (e.g. Redmi AirDots 3): 1. Pull the headphones out of the case. 2. Press and hold the touchpads on both headphones for 15 seconds. 3. Wait for the double beep (or flash red).
4. After reset, place the headphones back in the case for 30 seconds, then take out and try to connect again.

⚠️ Attention: Resetting removes all saved connection profiles if you have used multi-device headphones (e.g., a smartphone) + laptop, after resetting you will have to connect them again to each gadget.

If the second headphone never connects, try repeating the procedure starting with another headphone (for example, first left, then right).

Method 4: Update the firmware through the Mi Home app

If Xiaomi headphones are not synced due to outdated firmware, the solution is simple – to update the software through the official application. OTA-Updates (for example, Mi True Wireless) 2, Xiaomi Buds 3/4).

How to update firmware:

1. Install the Mi Home app (available for Android and iOS).
2. Connect the headphones to the smartphone via Bluetooth.
3. Open Mi Home, find your headphones in the list of devices and go to their settings.
4. Select the Firmware Update (if available).
5. Follow the instructions on the screen. Don't turn off your headphones during the update!

💡

Before updating the firmware, make sure that the headphones are at least 50% charged. If they run out during the process, this can lead to breakage.

If there is no upgrade option in Mi Home, check if your model supports it. OTA-For example, the budget Redmi AirDots 1 does not have this feature, and Xiaomi Buds 4 Pro updates automatically when connected to the Internet.

Method 5: Check and clean contacts (if the headphones are not charging)

If Xiaomi headphones don’t sync and don’t charge in the case, the problem may be contaminated or oxidized contacts, especially if you often carry headphones in your pockets or use them during training (sweat and dust can disrupt contact).

How to clean contacts:

• 🧴 Use a cotton swab dipped in alcohol (at least 70%) to gently wipe the contacts on the headphones and inside the case.
• 🔍 Check contacts for darkening or green plaque (a sign of oxidation).
• 🧲 If the contacts are magnetic (as in Xiaomi Buds 3), check if they are well attracted to the case.
• ⚡ After cleaning, place the headphones in a case for 1-2 hours for a full charge.

If the headphones are still not charging after cleaning, the problem may be a faulty case. Try charging the case from another cable or power supply. If the indicator on the case is not burning, it is likely that it will need to be replaced.

What to do if nothing helps: Diagnostics and service center

If you've tried all the ways, but Xiaomi's headphones still don't sync, maybe the problem is a hardware malfunction.

• 🔧 Check the headphones on another device (like a tablet or laptop) if they work normally, your smartphone is a problem.
• 📱 Update your smartphone firmware to the latest version (sometimes Bluetooth bugs are fixed in new versions of the software).
• 🛠️ Contact Xiaomi Service Center (especially if headphones are warranty).A list of official SC can be found on the website mi.com.
• 💰 If headphones are not warranty, evaluate the feasibility of repair.Sometimes it is cheaper to buy new than repair old (for example, repairing Redmi AirDots 2 can cost almost as much as new headphones).

Important: If the headphones detached after a fall into the water or a heavy impact, do not try to turn them on. This can lead to short circuit and final failure, in which case, immediately bring the device to the service.

Before visiting the service center, save a check or warranty card (if any), and write down the headphone serial number (usually listed on the case or in the Mi Home app), which will speed up the diagnosis process.
