How to Make Both Headphones Active Xiaomi: The Complete Guide

The situation when the wireless headset sounds music from only one ear, and the second is silent, is familiar to many owners of budget and flagship products. TWS-Often users perceive this as a breakdown of the speaker or battery, but in 90% of cases the problem lies in software dissynchronization of channels or activated mono-audio mode. Proper diagnosis begins with the understanding that the left and right headphones should work as a single system, exchanging data between themselves and the smartphone.

Recovering full stereo requires a series of actions, ranging from simply restarting the device to deeply resetting the settings. Don't panic if you notice that Xiaomi Redmi Buds or Mi True Wireless Earbuds have stopped working in pairs. Current Bluetooth communication protocols allow temporary failures that are easily fixed manually. It is important not to miss a single step, since a violation of the sequence can lead to the devices remaining in independent mode.

In this article, we will discuss in detail all possible causes of sound imbalance and offer proven methods for eliminating them. You will learn how to correctly perform a hard reset, adjust the channel balance in the Android system and use specialized utilities for managing the headset. Following the instructions will help return the device to factory parameters and ensure synchronous operation of both speakers.

Diagnosis of the problem: why is one headphone silent

Before we take any drastic measures, we need to rule out the trivial causes of malfunction. Often, one headphone simply discharged faster than the other because of the loose fit of the contacts in the charging case. Oxidation of contacts or dust can prevent the battery from charging normally, which causes the device to automatically turn off after a few minutes of operation. Check if the indicator burns when you install the headphone in the case.

The second common cause is a Bluetooth protocol software conflict: A smartphone may “think” that only one device is connected, ignoring the second one even when it is turned on, which often happens after updating the phone’s operating system or changing the playback device, in which cases a full reconnection is required, not just turning off Bluetooth.

⚠️ Attention: If one of the headphones is cracking or wheezing at maximum volume, the problem may be physical (damage to the speaker membrane.

It's also worth checking the availability settings in the smartphone itself. On Android, there's a Mono-audio feature that combines stereo channels into one and outputs sound through one speaker. Random activation of this option creates the illusion of a headset breakdown. To check this, go to the settings and make sure the balance slider isn't shifted completely to one side.

Basic setup and Bluetooth reconnection

The first and most effective step is to remove the device from the list of saved profiles. The smartphone could remember a configuration in which only one channel is active, and now automatically restores this error link every time you connect, you need to go to the Bluetooth menu, find your model (for example, Xiaomi Mi AirDots) and select "Forget device" or "Disable".

After removing the profile, place both earbuds in the charging case and close the lid for 10-15 seconds.This will completely break the connection and reboot the internal controllers of the headset. Then open the case, but do not press the pairing button for now. Make sure the indicators on both headphones are on or flashing, signaling readiness to work.

Now, search for new devices on your phone. When your model name appears on the list, click on it to pair. If it's successful, both earbuds should issue a distinctive audible signal about the connection. If only one sound appears, repeat the procedure by turning off Bluetooth on the phone.

It's important to understand that the synchronization process takes a while, and after extracting from the case, it takes the headphones a few seconds to find each other (TWS-You can only connect to the phone, and if you try to play music right away, it can only go to the host device.

Instructions for complete reset (Hard Reset) of the headset

If standard reconnecting didn’t help activate both channels, you need to perform a full factory reset, which cleans the internal memory of Bluetooth modules and eliminates software errors that block the second speaker. Different Xiaomi and Redmi models may have slightly different reset method, but the general principle remains the same.

Place both earbuds in a charge case. Make sure they sit tightly in the sockets and contact the charging pins. Press the touch pads on both headphones at the same time. In some models, such as the Redmi AirDots 2, you need to hold the sensors for about 5-7 seconds until the indicators light up red and then white.

Reset sequence for most models:


1. Put it in the case.




2. Hold the sensors for 15-20 seconds.




3. wait for the indicator to flash 3 times.




4 Remove and reconnect.

For models with a physical button on the case (such as Mi True Wireless Earphones 2), the algorithm is different: Open the lid without removing the headphones, and press the button on the case case case case. Hold it for about 10 seconds until the indicator on the front panel flashes quickly in white, which is a signal that the reset is successful.

After a successful reset, the headphones go into pairing mode. Remember to remove the old profile from the phone's settings again before reconnecting, otherwise the old settings may conflict with the new ones.

Setting up balance and mono mode in Android

Often the problem lies not in the headset itself, but in the settings of the smartphone operating system. Android has built-in features for people with hearing impairments that can be activated by accident. To check this, go to the Settings section, then select Accessibility and find the "Hearing" or "Audio" subsection.

So here you're looking at the "Mono-audio" item. If the switch is active, the system will bring the stereo to one channel. Turn off this option. Below should be the left/right balance slider. Make sure it's set straight in the center. Shifting the slider in either direction will cause one earbud to play louder or quieter than the other.

It’s also worth checking Xiaomi’s equalizer and sound effects settings (Mi Sound Enhancer).Sometimes activating certain profiles, such as Headphones or In-car, can misallocate frequencies between channels. Try disabling all audio enhancements and checking the headset as standard.

💡

System balance settings take priority over the settings of the headset itself, so check always need to start with the menu of special. Android features.

Use of the Xiaomi Earbuds app

For owners of original products Xiaomi and Redmi excellent diagnostic tool is the proprietary application Xiaomi Earbuds (formerly Mi True Wireless), which allows you not only to track battery power, but also to control the modes of operation of the headphones.

Once you have the headset on, open the app and go to your device settings, and you can find Mode of Use here. Make sure you select Use Both or Stereo. If left-only or right-only mode is activated, the second headphone will be silent even if it is technically sound.

The app also allows you to update the firmware of the headphones. Manufacturers often release updates that correct synchronization errors and improve connection stability. If the Firmware version is outdated, there may be periodic breaks in communication between the left and right modules.

• 🔋 Check the charge level of each headphone separately.
• 🎛️ Setting up sensor control (taps).
• 🔊 Choice of noise reduction mode (ANC).
• 🔄 Update of the built-in headset software.

You can also reset your settings if the physical buttons don't respond. The utility interface is intuitive, and all changes are instantaneous. This is especially useful for Redmi Buds 3 Pro and later models, where the management is completely software-based.

Removal of hardware faults and cleaning

If the software methods don't work, you should look at the physical condition of the device, and the sulfur and dust that accumulates on the speaker grid can create a traffic jam that makes the sound very quiet or disappears completely, and visually it can be invisible, but acoustic resistance increases dramatically.

To clean, use a soft toothbrush or cotton swab lightly soaked in alcohol (you need to squeeze well). Carefully walk along the speaker grid to remove impurities. Do not use sharp objects, as you can damage the membrane. Also wipe the charging contacts on the headphones themselves and inside the case with dry cloth.

⚠️ Warning: Do not immerse the headphones in water or pour liquid directly onto the speaker grid.

Check the battery integrity. If one earphone discharges much faster than the other (for example, 15 minutes vs. 3 hours), it may have degraded the battery, in which case the software reset will not help - you will need to replace the battery in the service center.

💡

To prevent contact oxidation, wipe the charging pins in the case and on headphones with a dry lilaless napkin once a week, especially after training or use in humid conditions.
