Why there is no sound in Xiaomi wireless headphones: the complete troubleshooting guide

You've turned on your favorite playlist, but you can't hear a sound from Xiaomi AirDots, Redmi Buds or Mi True Wireless? The problem of not having sound in your wireless headphones is one of the most common problems with Xiaomi users. It can be caused by both the usual settings of your smartphone and hardware breakdowns. In this article, we'll look at all possible scenarios, from software failures to physical damage, and give step-by-step instructions for restoring sound.

It's important to understand that if the headphones don't make sound on any of the ways you connect (Bluetooth, AUX, USB-C), it almost always indicates a hardware malfunction, but when the sound disappears periodically or only in certain applications, it's the software that's to blame. Let's start with the simplest checks and gradually move on to the difficult cases.

1. Checking basic settings: why the headphones are connected but no sound

The first thing to do is make sure that the problem is not with the device you're connected to, and often people forget about the trivial things like the sound on their smartphone being turned off or the incorrect output source.

Open the Quick Settings Panel on your phone (swipe down from the top edge of the screen) and check:

• 🔊 Volume level – it may be set to a minimum or turned off completely.
• 📵 Do Not Disturb Mode – If it is active, the sound may be blocked.
• 🔄 Source of sound output – sometimes the smartphone automatically switches to the speaker or other device.
• 🎧 Bluetooth Profile – In the headphone settings, a profile should be selected A2DP (for music, not HFP (call-in).

On Android, go to Settings → Sound → Output and make sure your headphones are selected. On your iPhone, open Control Point (up/down swipe depending on the model) and click on the audio output icon in the upper right corner.

⚠️ Note: If you use headphones with Xiaomi TV Or Mi Box, check the audio settings in the TV menu, and there's often a limit to Bluetooth audio output to save energy.

2.Resetting headphone settings: when a "hard" reboot helps

If the basic settings are fine but still no sound, try resetting your headphones to factory settings, which helps in 60% of cases when the problem is due to a software firmware failure or Bluetooth connection conflict.

Instructions for most Xiaomi models (including AirDots Pro 2, Redmi Buds 3 Pro, Mi True Wireless 2):

1. Put both headphones in the case and close the lid.
2. Pull them out and hold the touch buttons on both headphones for 10-15 seconds until the lights start flashing red and white.
3. After resetting, the headphones will automatically go into pairing mode (the indicator will flash white).
4. Remove the headphones from the list of conjugate devices on the phone and connect again.

For models with mechanical buttons (e.g. Redmi AirDots S), the reset is performed as follows:

1. Turn off the headphones (hold the power button for 3 seconds).


2 Press and hold the button on the right earpiece for 10 seconds until the red light flashes.




3. Repeat for the left earpiece.




4. Reconnect.

Make sure the headphones are charged (indicator green)

Check that they are not connected to other devices

Remove from the case and place at a distance of 10 cm from each other

Prepare the phone for a new pairing-->

If you've had a sound after the reset, but it's gone again, the problem might be the headphone firmware, and we'll talk about that in the next section.

3. firmware update: why older versions of software "muffle" sound

Xiaomi regularly releases updates for its wireless headphones that fix bugs with sound, connectivity and autonomy. If your headphones haven’t been updated for more than 3-6 months, there’s a high probability that the problem lies in outdated software.

You can check and update the firmware through the official Mi Home app (for AirDots, Mi True Wireless) or Xiaomi Wear (for Redmi Buds):

1. Open the app and find your headphones in the list of devices.
2. Go to the Settings section → Update the firmware.
3. If a new version is available, click Update and wait until it is completed (the headphones should be in the case and connected to charging!).

Important nuances:

• 🔋 Do not interrupt the update – this can lead to a complete loss of headphone performance.
• 📱 Update is possible only from Android phones (on iPhone this feature is not available).
• 🔄 After the update, reset the headphones (see previous section).

⚠️ Note: Headphones Xiaomi AirDots 3 Pro and later require to update the firmware connection to Mi Account. if you are not authorized, the update will not be available.

4.Bluetooth problems: conflicts, interference and limitations

Often, the sound is lost due to an unstable Bluetooth connection, which can be caused by:

• 📱 Conflict with other devices (earphones connected to both phone and laptop at the same time).
• 📡 Interference from other wireless devices (routers, microwaves, wireless mice).
• 🔄 An outdated version of Bluetooth on your phone (e.g. Bluetooth 4.0 instead of 5.0).
• 🚫 OS limitations (on iOS, some Xiaomi headphone functions work incorrectly).

How to diagnose and eliminate:

If the problem persists, try changing the Bluetooth codec in the developer settings (on Android):

1. Activate Developer Mode (7 times click on Build Number in your phone settings).
2. Go to Settings → System → For developers → Bluetooth settings.
3. Choose SBC (the most stable) or AAC (the best quality).

Settings → Applications → Show all apps → Bluetooth → Storage → Clear cache

5. Hardware malfunctions: when without repairs can not do

If all software methods have been tried, but there is still no sound, the problem is probably hardware.

1.Damage to the speakers

• 🔊 The sound is completely absent or severely distorted (wheezing, crackling).
• 🎧 One earpiece is working, the other isn't.
• 💧 Signs of moisture (condensation inside, corrosion on contacts).

In this case, you need to replace the speaker. In Xiaomi service centers, the cost of repair is 800-1500. ₽ Self-replacement is possible, but requires soldering and precision.

2. Bluetooth module malfunction

• 📶 The headphones do not connect to any device.
• 🔄 The indicator flashes blue, but pairing does not occur.
• 🔋 Fast battery discharge (module operates in enhanced mode).

Place them in a silica gel bag (from a shoe box) for drying. Trying to turn them on before drying completely will lead to a short circuit! 💡If the headphones don't turn on and react to charging, check battery integrity. Bloated batteries (seen by the deformation of the case) require immediate replacement - they can ignite! 6. Problems with specific models: Some Xiaomi headphone models have unique bugs that are worth knowing about: Xiaomi AirDots (all generations): 🔊 Problem: sound disappears when the charge level is low (10–15%). 🔧 Solution: Update your firmware to 1.4.0.8 or higher.
