When Xiaomi's wireless or wired headphones suddenly stop playing sound, they can be taken by surprise at any moment. Whether it's an important call, a favorite music on the road or watching a movie, the lack of audio is annoying and panicking. Often the problem is not the device itself, but a software failure, a wrong connection, or a banal battery discharge.
Before you bring your device to the service center, you need to conduct a thorough diagnosis. Owners of Redmi Note, Poco and Mi flagships face such problems regularly, and in 90% of cases they can be eliminated independently. It is important to understand that the Android system and the shell MIUI or HyperOS have their own features of managing audio devices.
In this article, we'll look at all the possible reasons why headphones might not work and suggest step-by-step solutions. We'll look at both software settings and physical factors that affect communication quality. Resetting Bluetooth module settings often solves a problem when other methods are powerless. Let's start with the simplest and most obvious steps.
Basic diagnostics and charge check
The first thing to do when the headphones are silent is to check their charge. Even if the lights are on, the energy level can be critically low for a stable audio stream. Some Xiaomi Earbuds models can connect to the phone at low charge, but not produce sound.
Put the headset in a charging case and make sure the contacts are clean.Oxidation or dust on the contacts can interfere with charging, creating the illusion of working.Wash the contacts with dry soft cloth and try charging the device for 15-20 minutes.
☑️ Diagnostics of headphone nutrition
It's also worth checking if the power saving mode on the smartphone itself is activated, which can limit the operation of Bluetooth background processes. Turn off the "Energy Saving" mode and try to play the track again. Sometimes it helps to simply turn off and turn on Bluetooth on the phone.
Problems with Bluetooth-connection
The most common reason Xiaomi headphones don’t work is because of pairing errors. A smartphone can “remember” a device, but the connection between them is already broken or unstable, in which case you need to remove the device from the list and pair again.
To do this, go to Bluetooth settings, find your headphones in the list, and click "Forget the device" or "Unpair the pairing." After that, place the headphones in the case, close the lid and open it again by holding the reset button (if any) or simply delivering them for pairing mode.
⚠️ Attention: If you have TWS-headphones, make sure both headphones are synchronized with each other. Often, the phone sees only one headphone (for example, only the left one) and the right one is silent.
How to perform a complete reset of TWS headphones
Remember that the distance between the phone and the headphones should be minimal when paired, and walls, metal structures and working microwave ovens can interfere with the connection process.
Sound and multimedia settings in MIUI and HyperOS
Xiaomi shells have advanced audio settings that can conflict with connected devices. If the headphones are connected but there's no sound, check the media settings. The volume may be twisted to a maximum on the phone, but zero in the headphones themselves.
Go to Settings → Sound and Vibration. Make sure your headphones are chosen as the output device, not the phone speaker. It is also worth checking the settings of Dolby Atmos or Hi-Res Audio - sometimes their inclusion causes incompatibility with the headphone codecs.
- 🎧 Check if the Mono-Audio mode is installed in special features, it can distort the sound.
- 🔊 Make sure the media volume slider is raised, not just the volume of the call.
- 📱 Turn off Absolute Volume in the Developer Menu if the sound is too quiet or intermittent.
Some versions of the firmware have a bug where the system doesn't automatically switch the audio stream, so try playing music and then putting on your headphones, and that force you to switch the output to your Bluetooth device.
Application conflicts and system failures
Sometimes the problem is not the hardware, but the application, for example, YouTube may not be producing sound while everything works in Telegram or the player, which indicates that the app cache is malfunctioning or incompatible with the current version of the OS.
Try clearing the cache of a problem app through Settings → Applications → Application Management. It’s also worth checking if there are third-party equalizers or amplifiers that can intercept the audio stream and block it from being transmitted to external devices.
Android system failures can also cause Bluetooth drivers to stop responding correctly, in which case a simple smartphone reboot often works wonders, resetting all temporary errors and restarting communication services.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Headphones are on the list, but no sound. | Failure of audio stream | Switch audio output manually |
| The phone doesn't see the device. | Headphones are not in pairing mode | Reset your headphones and turn them on again |
| The sound is interrupted. | Interference or low charge | Get closer, charge the device |
| Only one headphone works. | TWS desynchronization | Complete reset (Reset) |
Physical damage and hardware problems
And if the headphones fall, fall in the rain, or experience extreme temperature changes, the problem may be inside. In wired models, the cable often breaks at the plug or at the entrance to the earphone bowl.
Check the 3.5mm or USB-C plug for contaminants. Clothing pockets often accumulate pile that clogs the phone connector. Clean the connector carefully with a toothpick or compressed air, but act carefully to avoid damaging the contacts.
💡
To check the integrity of the wired headphone cable, slightly curve it in different places during music playback, and if the sound appears and disappears, a fracture inside, you need to change the cable or soldering.
In the case of wireless models, a sign of hardware failure is the lack of response of the indicators even after a long charge. If none of the software methods helped, probably the battery or Bluetooth module inside the headset failed.
Resetting network settings and flashing
If nothing works, you can try a radical method, resetting the network settings, which will delete all stored Wi-Fi passwords and Bluetooth pairings, returning the phone's network modules to factory status.
Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action and restart the phone. After that, try connecting the headphones as a new device.
⚠️ Note: Before resetting your network settings, make sure you remember passwords from your Wi-Fi networks, as they will have to be re-entered.
It’s also worth checking for updates for the headphones themselves through the Xiaomi Earbuds or Mi Wear app. Manufacturers often release patches that fix connection bugs and improve stability.
💡
The integrated approach: first charge and reboot, then reconnect, and only at the end - reset the network settings. Don't start with complicated methods.
