How to connect Xiaomi’s AirDots to your smartphone: 4 working methods + error solving

Why Xiaomi Headphones Don’t Connect the First Time – and How to Fix It

Xiaomi AirDots wireless headphones (including Redmi AirDots>, Mi True Wireless Earbuds and Xiaomi Buds) must connect to the phone in seconds — but in practice, users face problems: one headphone does not work, the connection is constantly broken or the device is not detected at all in the Bluetooth list, the reasons lie in the wrong sequence of actions, outdated firmware or conflict with other Bluetooth devices.

In this article, we’ll break down all the current connectivity options (including hidden features for Qualcomm QCC3040 models), explain how to reset your headphones to factory settings, and warn against typical bugs. The instructions are universal for Android (including MIUI, ColorOS, EMUI) and iOS (iPhone/iPad). If your AirDots are already connected but the sound is interrupted or the stereo balance is lost, click through to the “Problems” section.

Method 1: Standard Bluetooth connection (for all models)

This method works for 90% Xiaomi devices including Redmi AirDots 2/3, Mi AirDots Pro and Xiaomi Buds 4. The main rule: headphones must be fully charged (the indicator on the case is lit white or green). 20%, They may not appear in the list of available devices.

Sequence of action:

• 📱 Open Bluetooth settings on your phone: Settings → Connections → Bluetooth (Android) or Settings → Bluetooth (iOS).
• 🎧 Take both earbuds out of the case, they'll automatically turn on. Wait for the red and white light to flash).
• 🔍 In the list of available devices, find the name of your model (for example, Mi True Wireless EBs). basic_R or Redmi AirDots_3_R). Press it.
• ✅ Confirm the connection. If you request access to contacts/microphone, allow (this is required for Hands-Free profile).

-->

⚠️ Note: If only one headphone is displayed in the Bluetooth list (e.g. Redmi) AirDots_3_L), This means that the right (R) earphone is discharged or out of pairing mode. 10 Then pull it out again, they sync automatically.

Method 2: Connect via Mi Home (for supported models)

Some Xiaomi AirDots models (such as Mi AirDots Pro 2 or Xiaomi Buds 3 Pro) support advanced settings through the proprietary app. This allows you to update the firmware, customize gestures and enable low latency (important for games).

Instructions:

1. Download the Mi Home (Android) or Mi Home (iOS) app.
2. Sign in or sign in through your Xiaomi/Mi Account.
3. Click Add Device (+) → Select Audio Category → Find your AirDots model.
4. Follow the instructions on the screen. The app will automatically find the headphones in pairing mode.

After connecting to Mi Home, you will be able to:

• 🔊 Adjustment of the equalizer (preset profiles: Bass, Voice, Balance).
• 🎮 Low latency mode (Game Mode) – reduces lag to 80 ms (relevant to the current system) PUBG Mobile, Call of Duty).
• 🔄 Update of firmware (if a new version is available).
• 📱 Checking the charge level of each headphone and case.

💡

If your AirDots model is not displayed in Mi Home, check your account region. Some devices (e.g. Xiaomi Buds 4) require you to select China in your profile settings.

Method 3: Manual pairing for older models (AirDots 1 generation, Redmi AirDots S)

Outdated models (released before 2020) may not support automatic connectivity, requiring a forced reset before first pairing, and this method will also help if the headphones have previously been connected to another device and have “forgot” it.

Reset algorithm:

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the back of the case for 15 seconds until the indicator starts flashing red and white alternately.
3. Take the headphones out of the case - they will go into pairing mode.
4. Connect via Bluetooth as described in Method 1.

⚠️ Note: After reset, Xiaomi AirDots headphones may temporarily lose sync with each other (for example, sound will be heard in only one earphone:

1. Place both headphones in the case. 2. Close the lid and wait 30 seconds. 3. Open the lid - the headphones automatically synchronize. If the problem remains → go to the "Problem Solving" section (paragraph 3).

Method 4: Connecting to multiple devices (multipoint)

Xiaomi AirDots models on the Qualcomm QCC3040 chip (e.g. Mi AirDots Pro 2, Xiaomi Buds 3T) support simultaneous connection to 2 devices (e.g. phone and laptop), however, by default this feature is disabled.

Steps to enable multipoint:

1. Connect the headphones to the first device (for example, a smartphone).
2. Open Mi Home → Select your AirDots → Go to Additional Settings.
3. Find the option Multipoint (Dual Connection) and turn it on.
4. Now connect the headphones to the second device through standard Bluetooth search.

Important: With active multipoint, battery life is reduced by 15-20% due to the additional energy consumption for maintaining two connections.

Problem Solving: Headphones are not connected, sound is interrupted, stereo balance is lost

If Xiaomi AirDots refuses to connect or fails, 80 percent of the time it is software conflicts or hardware limitations that are to blame.

1. Headphones don't appear in the Bluetooth list

Possible causes and ways of correction:

• 🔋 Headphones/case discharged → Charge 10-15 minutes (the indicator should burn red while charging).
• 📵 Conflict with other Bluetooth devices → Disable all other gadgets (fitness bracelets, smart watches, speakers).
• 🔄 Firmware failure → Reset your headphones (see Method 3) and update the software via Mi Home.
• 📱 Bluetooth problems on your phone → Restart your smartphone or reset your network settings (Settings) → System system → Reset → Resetting network settings).

2.The sound is interrupted or interference is occurring.

Most often it is due to overloading of the Bluetooth channel or physical obstacles.

• 📶 Distance to the phone → Maximum stable distance: 8-10 meters without obstacles, walls and furniture reduce the range of action.
• 🎵 Bluetooth codecs → In Bluetooth settings, select the codec SBC (most stable) or AAC (AptX codec can cause stuttering on some phones.
• 🔄 Processor overload → Close the background apps (especially games and video players).
• 🔋 Low-charge headphones → At a charge level below 15%, there may be a jump in sound.

💡

If interference only occurs in one earphone, try swapping it (put the left earphone in the right ear and vice versa). If the problem has moved, the hardware is defective (requires repair).

3. lost stereo balance (sound only in one headphone)

This is one of the most common problems with Xiaomi AirDots.

• 🔊 Synchronization software failure → Perform reset (see Method 3).
• 📱 Sound settings on the phone → Check the stereo balance in Settings → Sound. → Audio balance (should be in the center).
• 🔋 Different levels of headphone charge → Fully discharge and charge both earphones to 100%.

⚠️ Warning: If one of the headphones (L or R) still doesn't work after reset, it may indicate damage to the contacts in the case:

1. Clean contacts in the case and on headphones with a cotton swab dipped in alcohol. 2. See if the "legs" of contacts are bent (a common problem after falls). 3. Try to place the headphone in the case at a different angle - sometimes a shift of 1-2 mm helps. If the contacts are damaged → a soldering or replacement of the case is required.

4. Headphones plug in but immediately switch off

Guilty:

• 📵 Conflict with energy saving settings → On Android, turn off battery optimization for Bluetooth: Settings → Annexes → Bluetooth → Battery → No restrictions.
• 🔄 Outdated firmware → Update the software through Mi Home.
• 📱 Google Services Failure (Relevant for Android) → Clear the cache of Settings → Annexes → Google Play Services → Memory. → Clear the cache.

💡

If the headphones turn off after exactly 5-10 minutes of use, the problem is that the Bluetooth controller overheats. Let them cool for 15-20 minutes, then reconnect.

Additional settings: how to improve sound and autonomy

Once connected successfully, you can optimize AirDots for specific tasks, such as music, calls or games.

1. Sound optimization

In the Mi Home app (if supported by your model):

• 🎶 equalizer → Choose Basa's preset+ for hip-hop or Voice for podcasts.
• 🔊 ANC (Active noise cancellation) → Include for models with support (e.g. Xiaomi Buds 3 Pro). ANC reduces working hours by 2-3 hours.
• 🎤 Microphone reinforcement → Useful for calls in noisy places (Settings) → Microphone → Voice reinforcement).

Extension of the time of autonomy

To make the headphones work longer:

• 🔋 Turn it off. ANC Transparent treatment if not required.
• 📴 Reduce volume to 60-70% (at maximum volume, energy consumption increases by 30%).
• 🔄 Turn off automatic connection to the last device (in Mi Home) → Settings → Auto-connection).
• 🌡️ Avoid using at temperatures below 0°C or higher than 35°C - this reduces the battery capacity.

3. Customization of gestures

By default:

• 👆 Double touch. → Reproduction/pause.
• 👇 Triple touch. → Next track (right earphone) / Previous track (left earphone).
• 👈 Holding 2 seconds → Calling the voice assistant.

In Mi Home, you can reassign gestures (for example, assign a double touch to a call to Google Assistant or Siri).
