How to sync Xiaomi Redmi wireless headphones

Modern. TWS-Xiaomi’s headphones, including the popular Redmi AirDots and Mi True Wireless lineups, have become the benchmark for affordable sound, but owners often face a situation where the right or left channel stops working at the same time, or the smartphone sees the device as two different gadgets. This is a classic sign of desynchronization, requiring manual intervention.

The process of reconnecting between the headset modules is not complicated, but requires precise adherence to the sequence of actions. Unlike conventional Bluetooth accessories, it is important not just to pair with the phone, but first to “friend” the headphones themselves with each other. Bluetooth protocol in budget models sometimes fails when switching between signal sources.

In this guide, we will take a look at all the nuances of how to properly sync your Xiaomi Redmi wireless headphones. We will look at the standard connection methods, the procedure for completely resetting the settings for different generations, and how to solve common connection errors.

Primary connection and basic setting

The first step to successful synchronization is to pair correctly. Many users make the mistake of removing both earbuds from the case at the same time, which can trigger the network search process in the wrong order. It is important to give devices time to self-identify to work smoothly for a Bluetooth connection.

First, remove one headphone (usually the right one) and wait for the indicator to flash. Only then pull out the second one. The smartphone should detect the device under a single name, such as Redmi AirDots, not as two separate Left and Right channels. If the list of devices displays two identical entries, the sync between them has not yet gone.

Make sure your smartphone has a wireless module activated and geolocation enabled. In modern versions of Android, location permission is often required to detect Bluetooth gadgets. Click on the device name in the list of available pairs.

💡

When you first connect, keep your headphones closer to your phone (no further than 10-15 cm) to avoid losing data packets during handshake.

Once the connection is successful, the system will issue a notification and the voice assent will confirm the status of "Connected". Now you can check the sound. If the audio comes from only one channel or sounds monophonic, you will need the reconnection procedure described below.

Resetting algorithm for Redmi AirDots and Redmi Buds models

If standard connectivity fails, you need to perform a full reset (Hard Reset), which clears the internal memory of the headphones from old pairing profiles. For the Redmi AirDots 1, 2, Essential and early versions of Redmi Buds, the process is performed mechanically through touch panels.

Put both earbuds in the charge case, but don't close the lid. Make sure they're fixed with the contacts and the lights are on. You'll need to pinch the touch areas on both earbuds at the same time. Hold them for 20 seconds. The indicators will flash red several times, then flash white (or red and white) three times.

• 🔄 Remove the headphones from the case completely.
• 📱 Open Bluetooth settings on your phone and select Forget Device for all Redmi-related records.
• 🔌 Put the headset back in the case on 5-10 seconds to reset the controller.
• 👆 Press the sensors for 20 seconds until the indicator flashes triple.

And after you do this, the headphones go into standby mode, and they have to automatically find each other, and the indicator of one of them will flash slowly, and the second will flash quickly or not burn, which means successful synchronization with each other, and now you can connect them to the smartphone as a new device.

Synchronization of Redmi AirDots 3 and Pro versions

Newer models, such as the Redmi AirDots 3, AirDots 3 Pro and Buds 3 Pro, have a different reset mechanism due to the lack of physical buttons and the presence of additional software.

For models with a function button on the case (usually a round button on the end or back of the case), the procedure is simplified. Open the case lid without removing the headphones. Press and hold the function button for 10 seconds. The indicator on the front of the case should light up in orange, which signals entry into reset mode.

In the case-free models (such as some versions of AirDots 3), the touch method is used. Remove the headphones, put them on a flat surface. At the same time, touch the touch zones on both headphones and hold for 5 seconds before turning off, then repeat the action and hold for 20 seconds before reset. The exact sequence can vary, so it's important to monitor the color of the indicator.

⚠️ Attention: When resetting headphones Pro-versions with active noise cancellation (ANC) Make sure they are not in active use mode to avoid driver conflict.

Once reset, search the device again via Settings → Bluetooth. New models may require an update via the Mi Home or Xiaomi Earbuds app to work correctly for all functions, including synchronizing high-quality codecs.

Use of Mi Home and Xiaomi Earbuds

For deep customization and diagnosis of the state of the headset, Xiaomi has developed specialized software. The Xiaomi Earbuds application (or the section in the Mi Home) allows you not only to update the firmware, but also to force the devices to synchronize if standard methods do not work.

Once you connect your headphones to your smartphone, open the app. If the device is compatible, it will show up on the home screen showing the charge of each channel separately. Here you can check the firmware version. Often desynchronization is caused by bugs in the old version of the software that are patched by the update.

In the settings menu inside the app, you can find a dual-channel mode or similar feature that forcibly checks the connection between the left and right modules, and the app allows you to reset your headphones in a software way, which is sometimes more effective than mechanically clamping buttons.

• 📲 Download the official app from Google Play or App Store.
• 🔗 Connect the headphones and open the application for automatic detection.
• 🔄 Check for updates in the "About the device" section".
• ⚙️ Use the reset function inside the app if available.

The use of official software is especially important for models with support for aptX Adaptive or LDAC, as improper configuration of codecs can lead to desynchronization of the audio and video stream.

Table of indicators and their value in synchronization

Understanding light is key to successful diagnosis: different colors and blinking frequencies tell the user about the current status of the device, and the table below is a summary for most Redmi and Mi TWS models.

Note that some variations may vary in color gamut, such as the absence of a white LED can be replaced by a green one. Always check the specific model's instructions if the indicator's behavior seems odd.

Solving problems with sound desynchronization

Even after a successful connection, users may find themselves in a situation where there is sound but it is not stereo, or one channel is behind in time, which can be caused by signal interference or a software failure in the smartphone operating system.

Try to turn off Bluetooth on all other devices within range. Sometimes headphones try to automatically reconnect to a previously familiar tablet or laptop, creating a priority conflict.

To do this, go to Settings → Applications → Show system processes → Bluetooth → Memory → Clear cache. After that, restart your smartphone. This procedure resets the connection stacks and often solves problems with “snagging” sound or channel desynchronization.

⚠️ Warning: Do not try to sync your headphones if the case charge is critically low.Unstable voltage can interrupt the firmware or reset process, leading to a malfunction of the controller.

If nothing works, there may be a hardware malfunction in one of the modules, in which case warranty repairs will be the only correct solution, but in 90% of cases, the methods described above bring the headphones back to life.

💡

The key to success is that sequence is more important than speed, so pause between retrieving your headphones and pressing the buttons so that the controller can process the commands.
