What to do if wireless headphones work separately Xiaomi

The situation when Xiaomi or Redmi wireless headphones stop working in pairs and start playing sound from only one side or broadcasting different tracks is one of the most common problems owners have. TWS-Users often find that after extraction from the case, devices do not find each other, turning into two independent mono-gadgets. This can happen after upgrading the smartphone, discharging the battery of one of the headphones to zero or a software failure in the Bluetooth module.

The main reason is that the internal logic of the left and right modules is out of sync. In normal mode, one headphone (master) connects to the smartphone and transmits sound to the second (slack), but when the communication protocol fails, they lose communication with each other. Fortunately, in most cases the hardware part is functional, and the problem can be solved by software methods without resorting to complex repairs or replacement of the device.

In this guide, we will take you through all the effective ways to restore sync, from simple reboots to complete resets. You will learn how to calibrate correctly, why it is important to clean up connection history, and what hidden features can help diagnose a malfunction. It is important to act consistently to eliminate software errors and return the gadget to the factory logic of operation.

Diagnostics of the problem and primary actions

Before you start taking drastic measures, you need to accurately determine the nature of the malfunction. Often users confuse desynchronization with battery discharge or contamination of contacts. If one earphone is silent completely, check if it is on the indicator when placed in the case. Perhaps the contact pads have oxidized, and the device simply does not charge, remaining off.

If both headphones are on, light up, but the sound is coming from one or both, but different (left channel in left, right channel in right, instead of stereo), then the connection between them is lost, in which case the smartphone sees them as two different devices or as one, but without the right stereo pair. The first step should always be a complete cleanup of the history of the pairing.

To do this, perform the following actions:

• 📱 Go to your smartphone’s Bluetooth settings and find your headphones in the list.
• 🗑️ Click on Forget the Device or Cancel the pairing for both headphones if they are displayed separately.
• 📴 Turn off Bluetooth on your phone completely, then turn it back on in 10 seconds.
• 🔌 Place both headphones in the charging case and close the lid on 10-15 seconds.

Once you've done this, try reconnecting them, and if the problem hasn't gone away, you'll need to take a deeper step into your device settings, and don't ignore this step, because old connection profiles may conflict with new mating attempts.

Complete Reset (Hard Reset)

The most effective way to solve the problem of desynchronization is to completely reset the headphones to the factory, which causes devices to forget all previous connections and forcibly initiates the search for a partner to create a stereo pair. The algorithm of actions may vary slightly depending on the model (AirDots, Earbuds Basic, Redmi Buds), but the general principle is the same.

First, make sure that both earbuds are in the case and charged at least 20-30%. If the charge is critically low, the reset process may be interrupted, which will lead to even more instability. Open the case cover, but do not remove the headphones.

Now you need to find touch pads or physical buttons. Most Xiaomi and Redmi models need to simultaneously press and hold the touch zones on both headphones for 20-30 seconds. In some models, such as the Mi True Wireless Earbuds Basic 2, the buttons can be on the case itself or require five times pressing. Watch for the indicator: it should light up red or start flashing white, which signals the beginning of the reset process.

⚠️ Warning: Do not remove the headphones from the case or close the lid during the reset, or the process will interrupt and you will have to start over.

After the lights flash (usually 3 times or flash red quickly), release the buttons. The headphones turn off. Put them back in the case, close the lid and wait 5-10 seconds. Then open the case - the headphones should automatically go into pairing mode, and one of them will flash quickly, waiting for a connection to the phone.

Manual synchronization of left and right earphone

If automatic reset didn’t work, you can try forced manual synchronization, a technique that often works for AirDots and Earbuds models, which tend to “lose” each other after upgrading the smartphone firmware, and the method is to get one headphone to become a master, and the second to join it without the phone.

First, remove the Bluetooth device on your phone and turn off the Bluetooth itself. Take both of the headphones out of the case. Now you need to turn them off quickly. To do this, press the touchpads on both of the headphones for 5-7 seconds until they turn off (the indicators go out). Then tap the touchpads three times quickly on each headphone. This action puts them in reconnection mode.

Now leave the headphones lying next to each other on 10-15 And then they're going to look for each other, and you're going to notice that on one of the headphones, the light will stop flashing a lot and start lighting up less often (once every few seconds), while the other one might go out or blink differently, which means that the stereo is restored.

Now you can turn on Bluetooth on your smartphone and search for devices. Only one gadget (like the Mi True Wireless EB Basic R) should appear on the list, not two separate devices. If you see two devices with the same name, then the synchronization failed, and the procedure should be repeated, perhaps with longer retention of buttons.

Working with Xiaomi Earbuds app and updates

Modern Xiaomi headphones, such as the Redmi Buds 3 Pro or Mi True Wireless Earphones 2, are closely integrated with the Mi Home ecosystem or the special Xiaomi Earbuds app. Often the problem of desynchronization is solved by updating the internal firmware of headphones, which fixes the bugs of the communication protocol.

Connect your headphones to your smartphone, open the app, and check the status of each headphone. If the app sees them as separate devices, try updating the firmware for each one in turn. Sometimes the process of updating on one earphone wakes up the other and restores communication.

The app also often has a "Hearphone Search" or audio calibration feature, which can force Bluetooth modules inside the headset to restart, and make sure the headphone control app version is also updated to the latest one available on Google Play or Mi GetApps.

💡

If you have an iPhone, use the Mi True Wireless Earbuds Basic 2 app (or the equivalent for your model) from the App Store, which allows you to reflash your headphones even on iOS, which often solves compatibility problems.

Clearing contacts and hardware nuances

Physical reasons should not be discounted: Dirt, earwax or oxidation can interfere with normal charge and communication. Carefully examine the contact points on the headphones themselves and inside the case. Even the thinnest film of fat can increase resistance and prevent the earpiece from charging or turning on.

To clean, use a cotton swab slightly soaked in alcohol or a special electronics cleaner. Gently wipe the contacts, trying not to damage the speaker mesh. After cleaning, let the alcohol completely evaporate (2-3 minutes) before placing the headphones in the case.

Also check the density of the headphones in the case. If one of them is not tight (for example, due to a deformation of a rubber mount or a pile), it may not charge, so when you take out the headset, one headphone is battery-operated and the other is already off, which creates the illusion of failure.

⚠️ Warning: Never use metal objects (needles, pins) to clean contacts inside the case, which can short-circuit and permanently damage the electronics of the charging case.

If after cleaning and all the software manipulations, one earphone still does not charge (the indicator in the case does not light up when the headphone is placed), the battery or charging controller inside the earphone may have failed, in which case the power supply or the entire module must be replaced.

Frequent questions and additional solutions

Sometimes the problem isn't with the headphones themselves, but with smartphone settings or third-party apps. For example, some Android battery optimizers may aggressively shut down Bluetooth services as energy-intensive. Try turning off power savings for Bluetooth and system services.

It's also worth checking if the headphones are connected to another nearby device.If you have a tablet, laptop, or smartwatch of the same ecosystem, they could automatically intercept the connection, leaving the phone without sound or creating a channel conflict.

💡

The main reason for the desynchronization is the mismatch between the left and right earbud firmware versions, and the complete reset causes them to update internal listings and align software versions.

In rare cases, reconnecting to another smartphone helps. If the headphones on the other phone are working correctly, then the problem is in the Bluetooth module of your main phone or its software. Try resetting the network settings on your smartphone (Settings → Connections → Network Reset).
