How to Make Two Xiaomi Wireless Headphones Work at the Same Time: The Complete Guide

You bought Xiaomi wireless headphones, but you've got a problem: Is there only one headphone running and the other one is silent or connected as a separate device? This is a situation that many owners of Redmi AirDots, Mi True Wireless, Haylou and other models of the brand know. The reasons can be different — from synchronization failure to hardware malfunctions, but in 90% of cases the problem can be solved independently.

In this article, we’ll take a look at all the working ways to connect two Xiaomi headphones at once, from basic actions (reboot, reset) to hidden functions in proprietary applications. You’ll also learn how to tell a software failure from a breakdown and when to contact the service. If you tried to connect headphones via Settings → Bluetooth and it didn’t work, don’t rush to throw the device away. There is a solution!

For convenience, we have divided instructions on firmware models and versions. If your headphones are released after 2021, look at the sections about Dual Mode and updates through Mi Home – these features appeared relatively recently and often solve the problem of “one working earphone”.

1.Why two Xiaomi headphones don't work at the same time: the main reasons

Before we get to the settings, it's important to understand what exactly went wrong.-5 Reasons why one of the headphones may not connect or disconnect after a few seconds:

• 🔋 The battery is discharged in one of the headphones (even if the indicator is on, the battery can be critically low).
• 📱 Synchronization failure between right and left earphone (frequent issue after phone firmware update).
• 🔄 Incorrect connection order – many Xiaomi models require first to connect the right earphone, and then the left.
• 🛠️ Damage to contacts in the charging case (unless the headphones charge the same way).
• 📲 Conflict with the firmware of the phone or headphones (relevant for devices on the MIUI 12+ Android 11+).

The critical nuance is that if the headphones were previously paired and then stopped, 70 percent of the time the sync failure is to blame, not the hardware failure, which means that the problem can be solved software-based, without repair, except for physical damage (falls, moisture) that require diagnosis.

How do you check what's going on? Try connecting the silent earphone to another phone or tablet, if it works, it's a problem with your device settings, and if it doesn't, it's probably the headphones themselves (discharge, firmware failure, damage).

2. Basic actions: reboot and reset headphones

Start with simple steps – they help in 50% of cases and do not require special knowledge.If Xiaomi headphones do not connect at the same time, follow the following steps in exact order:

1. Remove the headphones from the case and place them next to each other (no more than 10 cm apart).
2. Press the buttons on both headphones for 10-15 seconds until the indicators start flashing red and white (this is a reset signal). For models without buttons (for example, Mi True Wireless 2), use touch panels - touch and hold for 10 seconds.
3. Place the headphones back in the case for 30 seconds, then pull out - they should automatically synchronize (indicators blink synchronously).
4. Connect to your phone via Bluetooth by selecting your model name (e.g. Redmi) from your device list. AirDots_R — The right earphone will connect first, then the left will automatically join).

If the headphones don’t work together after reset, check:

• 🔋 Case and headphone charge level (indicators on the case should be green or white).
• 📱 Compatibility with your phone: Some Xiaomi models don’t work well with iPhones or older Android versions (below 8.0).
• 🔄 Availability of firmware updates for headphones (about this in the next section).

3. firmware update via Mi Home (for 2020 and newer models)

Many users are unaware that Xiaomi headphones can be upgraded through the company’s Mi Home app.This solves sync problems, adds new features (like Dual Mode mode for connecting to two devices at once) and fixes bugs.

How to update firmware:

1. Install the Mi Home app from Google Play or the App Store.
2. Sign up or sign in to your Xiaomi account (required! no account update is available).
3. Connect the headphones to the phone via Bluetooth.
4. Open Mi Home, press + → Add Device → Headphones and select your model.
5. After you connect, go to Device Settings → Firmware Update. If a new version is available, click Update.

Important: during the upgrade, do not remove the headphones from the case and do not turn off Bluetooth. Interrupting the process can lead to the "bricking" of the device.

If your model doesn’t support an update via Mi Home, try alternative sync methods from the following section.

💡

After updating the firmware, reset the headphones (press the buttons for 10 seconds) – this will help to avoid conflicts with previous settings.

4. Manual pairing of headphones (if automatic synchronization does not work)

If the headphones are still connected separately after resetting and upgrading, try forcefully synchronizing them manually, which works for most Xiaomi models, except for the newest ones (for example, the Earbuds 4, where synchronization is automatic).

Redmi AirDots / Mi True Wireless 1/2

1. Take both headphones out of the case and put them next to you.
2. On the right earphone, press the button for 5 seconds until the indicator starts flashing red and white (pairing mode).
3. On the left earpiece, do the same, but hold the 10 seconds button until you hear the beep (this means the left earpiece is looking for the right one).
4. Wait 10 to 20 seconds, the lights on both headphones should flash in synchronous white, and then connect to the phone.

For touch-controlled models (e.g. Mi True Wireless 2 SE):

• Touch and hold the touchpad on the right earphone for 5 seconds.
• Repeat the same on the left, but hold on for 15 seconds until you hear a double beep.
• Wait for synchronization (indicators should be green).

If the headphones are still not synced, check:

• 🔌 Contacts in the case - clean them with a cotton swab dipped in alcohol (oxidation can interfere with charging and synchronization).
• 📵 Interference from other devices – disable nearby Bluetooth speakers, smart watches or other headphones.
• 📱 Bluetooth settings on your phone - in Settings → Bluetooth → Additionally, disable the "Automatic Connection" option and try to connect again.

5. Specific Model Problems: Redmi AirDots, Mi True Wireless, Haylou

Each Xiaomi model has its own "diseases" and let's look at the most common and ways to solve them.

Redmi AirDots (All Generations)

A common problem: after upgrading to MIUI 13/14, the headphones stop connecting at the same time.

• Remove the headphones from the list of Bluetooth devices.
• Turn on the developer mode on the phone (click 7 times on the MIUI version in the phone settings).
• Go to Settings → Additional → Developers → Debugging Bluetooth and enable the option “Enable A2DP”.
• Reconnect the headphones.

Mi True Wireless 2 / 2S / 2SE

Problem: The left earphone plugs in, but it shuts down immediately.

1. Open the Mi Home app and go to the headphone settings.
2. Turn off the "Dual Mode" option (if enabled).
3. Reset the headphones (press the touch panels for 15 seconds).
4. Connect to the phone and check the work.

Haylou GT1 / GT2 / GT6

Problem: The headphones are connected separately, but they don't work in pairs. Solution: Use Haylou Fun's proprietary app:

• Download Haylou Fun from Google Play.
• Connect your headphones through the app (not via Bluetooth phone!).
• Go to Settings → Reset and perform reset.
• After restarting, the headphones should sync automatically.

💡

For Haylou models, be sure to use a proprietary app – standard Bluetooth connection often works incorrectly.

6. Hardware problems: when to carry in the service

If none of the software methods worked, there may be a problem with the hardware, and here are the signs that the headphones need to be diagnosed at the service center:

• 🔋 One of the headphones does not charge in the case (the indicator does not burn or flashes red).
• 🎧 The sound in one headphone is distorted (wheezing, crackling, quiet sound).
• 🔌 The headphone is not defined by any device (phone, tablet, PC).
• 💧 Visible damage: traces of oxidation on the contacts, bloated battery, cracks on the body.

The most frequent hardware breakdowns:

Official Xiaomi service centers in Russia:

• 📍 List of CC on the Xiaomi website (select with the mark "Authorized").
• 🛠️ Unofficial workshops are cheaper, but the risk of running into poor-quality repairs (check reviews).

⚠️ Note: if the headphones are warranty (usually 12 months), do not open them yourself - this will void the warranty.

7. Alternative methods of use (if the synchronization is not restored)

If you have not managed to make both headphones work at the same time, but each of them works separately, you can use them alternately or in non-standard scenarios:

• 🎵 Music on a single headphone: connect the right or left earphone as a separate device (in some models, for example, Redmi AirDots 3, this works stably).
• 📞 Many Xiaomi models support Mono mode for calls – sound will only go to one headphone, but the microphone will work.
• 🎮 For PC or TV: Connect your headphones to your computer or Smart TV — Sometimes synchronization works better than with a smartphone.
• 🔄 Role sharing: In some models, you can assign the left earphone to the main (via Mi Home), if the right one does not work.

If you use headphones for sports or walking, you can buy a strap for one earpiece (costs 100-300). ₽) — You won’t lose it and you can listen to music in mono mode.

⚠️ Note: If you decide to sell a faulty headphone, be sure to mention in the description that they work only separately.
