Why Xiaomi Headphone Is Silent: How to Get Back Stereo Sound in 5 Minutes

You pulled both Xiaomi wireless headphones out of the case, but the sound comes from only one? Or does the right/left headphone connect separately and they refuse to work together? This problem is familiar to many owners of Redmi AirDots, Mi True Wireless Earbuds or Xiaomi Buds. Most often the reason lies in the failure of synchronization between the headphones — they “forget” that they should work as a pair.

In 90 percent of cases, the problem is solved without going to the service center, so you just reset the headphones and repair them. The algorithm differs from Xiaomi to model, and some actions (e.g. forced reset) can lead to loss of functions like anti-noise or touch control. TWS-headphone.

If you've tried reconnecting your headphones over Bluetooth, but the result is the same, don't be quick to blame the manufacturer. You may have missed a key step in the setup. We'll look at not only the standard methods, but also the "hidden" features of the I-firmware that are not written in the official instructions.

Why Xiaomi Headphones Stopped Playing Together: 5 Reasons

Before you start setting up, it’s important to understand what caused the synchronization break, and here are typical scenarios that make Xiaomi headphones work separately:

• 🔋 Battery discharge up to 0% in one of the headphones. If the battery is completely dead, the earphone can "fall out" of the pair and not connect automatically after charging.
• 📱 Failure of firmware after updating via Mi Home or Xiaomi Wear. Especially relevant for models with support ANC (noise-canceling).
• 🔄 Forced connection to another device, for example, if you manually selected a right or left earphone on the Bluetooth menu.
• 🛠️ Mechanical damage to contacts in the case: if the headphones are not charged at the same time, they can "lose" each other.
• 📡 Interference from other Bluetooth devices. Rarely, but it happens that headphones conflict with smart watches or speakers of the same brand.

The most insidious reason is a software reset of one of the headphones, which happens if you hold down the reset button for too long (for example, on the Redmi AirDots 3 Pro) or interrupt the process of updating the firmware, in which case the headphones stop “seeing” each other, and they need to pair again, as when you first connect.

⚠️ Note: If Xiaomi headphones started playing separately after falling or getting moisture, the problem may be damage to the antenna module.

Method 1: Quick Case Reset (for all Xiaomi models)

This is a universal method that works on 99% TWS-Headphones brand, including Mi True Wireless Earbuds Basic 2, Redmi Buds 4 and Xiaomi FlipBuds Pro. The point is to force the headphones back to mating mode.

You'll need:

• 🔌 Charged case (minimum 30% battery).
• 📱 Smartphone or PC with Bluetooth enabled.
• ⏳ 2-3 minutes of time.

Steps:

1. Place both earphones in the case and close the lid. Wait 10 seconds.
2. Open the case cover and hold the reset button (usually located on the back) for 15-20 seconds until the indicator starts flashing red and white alternately.
3. Close the case cover, wait 5 seconds and open again. The headphones should automatically sync (the indicators will flash in sync with white).
4. Connect the headphones to the device via Bluetooth, as when you first use it.

Both earphones flash white at the same time.

The Bluetooth menu displays one device (e.g., "Redmi Buds 4") rather than two separate devices.

The sound comes from both headphones when playing the test track.

If after this action, the headphones are still playing separately, move on to the next method, and you may need a deeper reset through the app.

Method 2: Reset via Xiaomi Wear app (for models with ANC)

Xiaomi’s active noise-canceling headphones (FlipBuds Pro, Buds 4 Pro) have advanced settings in the company’s app. Sometimes resetting through it is more effective than hardware rebooting.

Instructions:

1. Install the Xiaomi Wear app (for Android) or Mi Home (for iOS) from the official store.
2. Connect at least one headphone to your phone (even if the other one is silent).
3. Open the app, find your headphone model in the list of devices.
4. Go to Settings → Reset (or Reset in English version).
5. Confirm the reset and wait for the headphones to reboot (the indicators will go out and blink again).
6. Remove both headphones from the case – they should automatically sync.

⚠️ Note: After resetting through the application on models with ANC (FlipBuds Pro, Buds 4 Pro) may need to re-set the noise reduction level. If the function stopped working, update the headphone firmware in the Enterprise Application Software section.

Method 3: Manual pairing of headphones (if reset did not help)

If standard methods don’t work, try force-pairing the headphones together, which is suitable for models without a reset button (e.g. Redmi AirDots 2) or when one earphone is “not responding.”

Algorithm:

1. Remove both headphones from the case and hold the touchpads on both for 10 seconds until the indicators start flashing red.
2. Place the headphones back in the case, close the lid for 10 seconds, then open.
3. Wait until the indicators start flashing white in unison (this is a signal of successful synchronization).
4. Connect your headphones to your phone via Bluetooth. If the list of devices shows two separate headphones (Redmi) Buds_L redmi Buds_R), Remove both and search again.

Critical nuance: on models with a wear sensor (for example, Xiaomi Buds 3 Pro) before reset, you need to turn off the Autopause function when you shoot in the application settings.

Method 4: Update firmware (to fix software failures)

If the headphones started playing separately after updating the smartphone or the device itself, the problem may be incompatibility of the firmware versions, especially for the Xiaomi Buds 4 Pro and FlipBuds Pro, where the firmware is responsible for synchronizing channels.

How to update software:

1. Install the latest version of the Xiaomi Wear app.
2. Put the headphones on the phone.
3. Open the Corporate Software tab in the device settings.
4. If an update is available, click Update and wait until it is completed (don’t interrupt the process!).
5. After the update, reset the headphones (method 1 or 2).

If the update doesn't work, try rolling back the firmware to the previous version.

• 📥 Download the firmware archive for your model from the official Xiaomi website (support section).
• 🔧 Use the Mi Flash Tool for manual firmware (instructions are available on the forums) 4PDA).

⚠️ Warning: Manual firmware updates may result in loss of features such as transparent mode or gesture customization. Before the procedure, back up your settings in the Xiaomi Wear app (Section Backups).

Case problems: why headphones are not synchronized

If all software methods have been tried, but the headphones are still playing separately, the problem may lie in the charging case.

• 🔌 Oxidation of contacts – headphones do not charge at the same time, one of them is constantly discharged.
• 🔋 Case battery bloating - the cover closes poorly, the charge indicator flashes chaotically.
• 📡 Bluetooth antenna damage – headphones are synchronized only outside the case.

How to check the case:

1. Check the contact areas in the case and on the headphones. If there's a green coating, wipe them with alcohol.
2. Try charging the case with another cable. Sometimes the problem is the faulty one. USB-port.
3. Put the headphones in the case and press them a little, and if the charge indicator only lights up when you press it, the contacts need repair.

If the case is physically damaged and the headphones are still warranty, contact the Xiaomi service center. Otherwise, you can try to replace the battery of the case yourself (video instructions are available on YouTube).

💡

To extend the life of the case contacts, wipe them once a month with a cotton swab dipped in isopropyl alcohol, which will remove oxides and improve conductivity.

What to do if nothing helps: alternative solutions

If all of the above methods have not worked, consider the following options:

• 📱 Use the headphones separately. Some models (e.g. Redmi AirDots 3) support Mono mode, where you can listen to music only through one earpiece.
• 🔄 Try connecting to another device. Sometimes the conflict arises because of the features of the Bluetooth stack of the smartphone (especially on the iPhone).
• 🛠️ If the headphones are guaranteed, the repair will be free. The average cost of diagnosis is 300-500 rubles.
• 🆕 Buy a new kit. Xiaomi prices TWS-Headphones start from 1,500 rubles (for example, Redmi Buds 4 Lite).

Before buying new headphones, check if your smartphone supports aptX or AAC codecs. Some Xiaomi budget models (such as Redmi AirDots 2) work only with SBC, which affects the sound quality.

💡

If the headphones stop playing together after a fall or contact with water, self-repairing can make the problem worse.
