Xiaomi Redmi wireless headphones are a popular solution for music lovers and active users, but sometimes owners face a problem: one of the headphones stops working or does not connect to the phone, most often due to a loss of synchronization between the left and right modules. Unlike wired analogues, TWS-Headphones (True Wireless Stereo) require pre-patching with each other before they can connect to a smartphone or other device.
In this article, weβll look at all the ways two Redmi headphones can pair, from standard procedure to forced reset and manual reconnect. Youβll learn why the headphones can βunconnect,β how to check their current status, and what to do if one of the modules doesnβt respond to presses at all. The instructions are relevant for all popular models: Redmi Buds 3/4, AirDots, Earbuds S and other Xiaomi lines.
Important: the pairing procedure may differ depending on the version of the headphone firmware and the smartphone model. If you use the device on iOS, some steps will require additional actions (we will discuss this below).
Why Xiaomi Redmi headphones are βdecouplingβ?
Before you start setting up, you need to understand the cause of the problem. Redmi headphones lose sync with each other for several key reasons:
- π One module's battery discharge, and if one earphone is completely depleted and the other is not, they can forget each other.
- π± Misaligned disconnection from your smartphone, such as if you pulled your earbuds out of your ears without turning them off via the Bluetooth menu.
- π Firmware failure. Rarely, but it happens after an update or abrupt power outage.
- π§ Mechanical damage: Falling or getting moisture can disrupt the Bluetooth chip in one of the headphones.
- π Connecting to multiple devices. If the headphones were trying to connect to two smartphones at the same time, it could have knocked the settings.
In 80 percent of cases, the problem is solved software-based, you just reset the settings and re-arrange the modules, but if one of the headphones does not turn on or emit audio signals, this may indicate a hardware malfunction of the Bluetooth controller, which cannot be fixed on its own.
β οΈ Note: If one of the headphones flashes red after reset and does not respond to pressing, do not try to disassemble it yourself. In Redmi Buds 4 Pro and later, glue is used to seal the body - unprofessional repairs will lead to loss of water protection.
Method 1: Standard pairing (if the headphones are new or reset)
If youβve just bought headphones or have reset your headphones, use this method.Itβs suitable for most Xiaomi Redmi models, including AirDots, Buds 3 Lite, Earbuds S, and more.
Sequence of action:
- Put both earphones in the charger case and close the lid. Wait 10 seconds.
- Open the case cover. The headphones must automatically turn on (the indicator blinks).
- Press and hold the touchpad on both headphones simultaneously for 10-15 seconds until the indicators start flashing alternately red and white.
- Wait until both earbuds emit a beep (usually a short double squeak) which means they are paired with each other.
- Now connect them to your smartphone via Bluetooth as usual.
If the indicators flash only white or red in step 3, but not alternately, the pairing failed. Try repeating the procedure by holding the buttons longer (up to 20 seconds).
Make sure both earphones are charged (the indicator on the case is green)
Use the original charging cable (not all cables support data transmission)
Check that the headphones are clean (dust in the case contacts can block charging)
Turn off Bluetooth on other devices nearby (may interfere with search)-->
Method 2: Forced resetting (if the standard method does not work)
If the headphones were previously paired with another device or the connection was βhungβ, a complete reset may be required, which removes all stored pairs of Bluetooth and returns the headphones to the factory settings.
Instructions for Redmi Buds 3/4, AirDots 2/3:
- Press and hold the touchpad on both headphones for 25 to 30 seconds until the indicators start flashing red (3 times in a row).
For the Redmi Earbuds S and Buds 3 Lite models, the reset process is slightly different:
1. Get the headphones out of the case.
2.Push and hold the touchpad on the left earphone for 10 seconds until red flashes.
3. Repeat the same for the right earpiece.
4. Place both headphones back in the case and close the lid for 10 seconds.β οΈ Note: After reset, Xiaomi Redmi headphones can be temporarily identified in the list of Bluetooth devices as LE-... Mi True Wireless... Itβs OK to just connect to them as a new device.
Method 3: Manual pairing via Mi Home app (old models) Some Xiaomi Redmi models (e.g. AirDots Youth Edition) support pairing via the branded Mi Home app. This method is useful if the headphones don't want to connect in the standard way. Install the Mi Home app from Google Play or the App Store. Open the app and sign up (or log in to Xiaomi account (+) β Choose the Audio category β Headphones. Follow the instructions on the screen. The app will suggest that the headphones be paired (usually a long press on the touchpad), and once successfully connected, the app will have a headphone control panel where you can update the firmware or reset the settings. If the app doesn't find headphones, try it: π± Reboot your smartphone. π Remove the headphones from the case and put them back again. πΆ Turn off mobile internet (sometimes Mi Home conflicts with background updates). What to do if Mi Home can't see the headphones? If the app doesn't detect the device, try: 1. Delete the app cache (Settings) β Annexes β Mi Home β Memory. β Clear the cache. 2 Connect to the headphones via standard Bluetooth and then open the Mi Home - sometimes the device is determined automatically. 3. Use another smartphone (on some firmware) MIUI There are bugs with the detection of accessories).
Table: Comparison of pairing methods for different Redmi models
| Model headphones | Standard pairing | Forced discharge | Support for Mi Home | Features |
|---|---|---|---|---|
| Redmi Buds 4 Pro | β (hold on) | β (hold on) | β | Supports LC3 codecs, requires MIUI 13+ for full compatibility |
| Redmi AirDots 3 | β (hold on) | β (hold on) | β | Frequent synchronization problems after firmware update |
| Redmi Earbuds S | β (hold out) | β (resetting each headphone separately) | β (just basic settings) | No AAC support, only SBC |
| Redmi Buds 3 Lite | β (hold on) | β (hold on) | β | The most budget model, often loses communication at low charge |
If your model isn't in the table, try a universal method: hold the touchpads on both headphones until the indicators start flashing red and white alternately. 90% model Xiaomi/Redmi.
Method 4: Checking and calibrating sound after pairing
Even if the headphones are successfully paired, sometimes there are problems with the sound: one earphone is quieter, or you hear a stereo imbalance.
- π Incorrectly adjusting the balance in the smartphone.
- ποΈ Failure in the firmware of headphones.
- π Different levels of charge in the left and right modules.
How to eliminate the imbalance:
- On Android: Go to Settings β Special Features β Sound settings. Check the Balance stereo slider - it should be in the middle.
- On iOS: Open Settings β Universal Access β Audiovisual Content. Make sure that the stereo balance setting is set to 0.
- Charge your headphones to 100% (the difference in charge level can affect the volume).
- Reset the headphone settings (see Method 2) and pair them again.

If one earpiece is quieter, try swapping them (change left and right in your ears) and if the problem persists, the specific module is faulty, not the settings.
Frequent Mistakes and How to Avoid Them
Many users make common mistakes when pairing Xiaomi Redmi headphones, which leads to repeated crashes.
- π« Use a non-original charging cable, and cheap cables may not provide stable power, which causes the headphones to be out of sync.
- π« Interrupt the reset process. If you release the buttons ahead of time, the headphones can "hang" in intermediate mode.
- π« Connect headphones to multiple devices at the same time. Multithreaded mode (for example, to the phone and laptop) often confuses settings.
- π« Keep the headphones out of the case. A long time outside the charge case drains the battery to zero, which leads to a reset of the connection.
Also pay attention to the indicators of the state:
- π’ Green is full charge.
- π΄ Red: Low charge or error.
- βͺ White flashing - readiness to pair.
- π’π΄ Alternate blinking β successful pairing between headphones.

If the headphones are still out of sync after all the manipulations, check them on another smartphone. If the problem persists, it is a hardware malfunction that needs repair.
