Xiaomiβs True Wireless Stereo (TWS) wireless headphones allow you to use both headphones simultaneously for stereo sound or connect them separately in mono mode. However, many users face the problem: after buying or resetting the settings, the headphones stop syncing with each other, working only one. In this article, we will discuss all the working ways to properly connect two Xiaomi wireless headphones between themselves, including the Redmi Buds models, Mi True Wireless, Xiaomi FlipBuds and others.
The problem is most often caused by a firmware failure, improper connection order, or mechanical disconnection (for example, if one earphone was lying unused for a long time). It is important to understand that the synchronization process is different from the usual connection to a phone - here you need to make the headphones "see" each other. We tested all methods on current models in 2026 and collected checklists for each case.
Why Xiaomi headphones do not connect with each other: the main reasons
Before we get to the instructions, let's figure out what exactly prevents the headphones from syncing, and 80 percent of the time, one of the following factors is the problem:
- π Battery discharge β if one of the headphones is under 10%, they wonβt be able to establish a connection.
- π± Firmware error β after updating the software via Mi Fit or Xiaomi Wear, the configuration may be lost TWS.
- π Incorrect order of inclusion β headphones need to be activated in strict sequence (first right, then left or vice versa β depends on the model).
- π οΈ Mechanical damage to contacts β if the headphones fell or got wet, the connection between the boards could be disrupted.
- π‘ Interference from other devices β a nearby router running at 2.4 GHz or other wireless gadgets can block the signal.
Especially often, the problem occurs after resetting settings through a long push of a button (for example, on the Redmi Buds 3 Pro or Xiaomi Buds 4). In this case, the headphones βforgetβ each other and require re-tethering, and synchronization can be disrupted if you tried to connect the headphones to two different phones at the same time.
β οΈ Note: If Xiaomi headphones do not respond to buttons at all and do not charge, the problem may be a malfunction of the battery or controller.
Method 1: Standard button synchronization (for most models)
This method works for Redmi Buds 3/4, Mi True Wireless 2, Xiaomi Buds 3/4 and other models with a physical or touch button. The main rule is that all manipulations are performed with the headphones turned off (they should not flash white or blue).
Algorithm of action:
- Put both headphones in the case and close it for 10 seconds to reset the current settings.
- Take out only the right earphone (it is usually the lead) and hold the switch on 5-7 seconds until the indicator starts flashing red and white (pairing mode).
- Put the right earphone back in the case and get the left one. Hold the button until it flashes blue.
- Wait 10-15 seconds β if the synchronization is successful, both earbuds will flash white at the same time.
- Connect them to your phone as usual (via Bluetooth).
If the lights flash red or go out, repeat the process by changing the order (left first, then right). On some models (for example, Xiaomi Buds 4 Pro) to reset, you need to hold the button for 10 seconds until the beep sounds.

Method 2: Long press reset (for models without a button)
New Xiaomi models, such as the FlipBuds Pro or Buds 4 Lite, often lack physical buttons. Instead, touch controls or automatic synchronization are used. If the headphones stop connecting, try a hardware reset:
Instructions:
- Put both headphones in the case and connect it to the charger.
- Open the case cover and hold the touchpad on both headphones simultaneously for 20 seconds. On FlipBuds Pro, you need to touch the area next to the microphone with your finger.
- The indicators on the headphones should go out, and then blink with purple (recovery mode).
- Close the case for 30 seconds, then take out the headphones - they should automatically sync.
If the headphones donβt connect after reset, check the firmware version through the Xiaomi Wear app. Some models (such as the Redmi Buds 4 Active) require a software update to fix TWS errors.

Method 3: Forced synchronization through the Xiaomi Wear app
If manual methods donβt work, use the official Xiaomi Wear app (formerly Mi Fit), which is suitable for all models that support firmware via a smartphone. Importantly, the app should be the latest version (check the updates in Google Play or App Store).
Step-by-step:
- Install Xiaomi Wear and sign up (or sign in via your Mi Account).
- Connect only one headphone (any one) to your phone, and it will appear as "Incomplete pair" in the app.
- Go to Settings of the device β Additional β Synchronization of headphones.
- Click Find the second headphone and follow the instructions on the screen.
- After successfully binding, restart both headphones (put in the case for 10 seconds).
If the application does not contain the item "Syncion of headphones", update the firmware of the headphones:
- π² Go to the Device Profile β Update of the PO.
- π Wait for the download and installation to be completed (donβt interrupt the process!).
- π Make sure that the case charge is at least 50%, otherwise the update may end with an error.
β οΈ Note: Some firmware (e.g. Redmi Buds 3 Lite) resets the uniformity settings after the update (EQ). You will have to re-configure them in the Sound section.

If the Xiaomi Wear app doesnβt see headphones, try clearing the appβs cache in your phoneβs settings (Settings β Apps β Xiaomi Wear β Memory β Clear the cache).
Table: Synchronization features for popular Xiaomi models
Each Xiaomi headphone model has its own nuances when connecting, and in the table below we have collected the key differences for the most common gadgets:
| Model | Lead earpiece | Color of indicator during synchronization | Receipt time of reset button | Is firmware required? |
|---|---|---|---|---|
| Redmi Buds 3/3 Pro | Right. | White + Red β White | 5 seconds | No (if the software version is β₯ 1.4.0) |
| Xiaomi Buds 3/3 Pro | Left | Blue β purple | 7 seconds | Yes (update via Xiaomi Wear) |
| FlipBuds Pro | Automatic choice | Green β white | 20 sec (sensor) | Yes (critical for versions below 1.7.2) |
| Redmi Buds 4 Active | Right. | Red. β white-coloured | 10 seconds. | No. |
| Mi True Wireless 2 | Anybody. | Orange β white | 3 seconds (short press) | Yes (unless synchronized after reset) |
If your model is not in the table, try the universal method: hold the buttons on both headphones simultaneously for 15 seconds, then put them in the case for 1 minute.
Method 4: Alternative methods for complex cases
If the standard methods didn't work, try one of these options, which helps in 90% of the "hopeless" cases where the headphones refuse to connect despite all the manipulation.
The cold start method
Suitable for models with removable batteries (for example, old Redmi AirDots):
- Take the case apart (take the lid with a screwdriver carefully).
- Disconnect the battery case for 1 minute, then connect back.
- Close the case and connect to the charger for 10 minutes.
- Get your headphones out β they should automatically sync.
Use of the second telephone
Sometimes the headphones stick on one device to reset the band.
- Connect both earphones separately to another phone (not the one they were previously tied to).
- In the Bluetooth settings of the new phone, delete them ("Forget the device").
- Return the headphones to the case, then take out and try to sync again.
Update via PC (for advanced users)
If the firmware through Xiaomi Wear does not help, you can try to update the software manually:
- Download the latest firmware for your model from the official website en.miui.com (section "Support").
- Rename the file to fw_update.bin Put it in the root of the phoneβs memory.
- Connect the headphones to your phone and in Xiaomi Wear, select Manual Update.
β οΈ Warning: Wrong firmware can turn headphones into a brick. Use only files designed for your model (check the version number on the sticker inside the case).

If the headphones after all the manipulations and did not sync, the problem may be a hardware malfunction of the Bluetooth module. In this case, contact the Xiaomi service center with a check about the purchase (the warranty on the headphones is usually 12 months).
Frequent Mistakes and How to Avoid Them
Many users make the same mistakes when trying to connect Xiaomi headphones, and here are the most common mistakes and ways to correct them:
- β Use of non-original cables - cheap cables may not provide enough current to charge the headphones. Use only a kit cable or a certified one. USB-C Quick Charge Supported.
- β Interrupting the synchronization process β if you put your headphones in the case or turn off Bluetooth while the lights blink, the connection will reset.
- β Ignoring firmware updates β bugs are often fixed in new versions of the software TWS. Check out updates in Xiaomi Wear once a month.
- β Connect to multiple devices at once β Xiaomi headphones do not support multipoint (simultaneous connection to your phone and laptop.
Another common mistake is trying to sync your headphones when one of them is discharged to 0%. Even if the indicator is 1-2%, this may not be enough to set up a connection. Charge both earphones to 100% before the procedure.
