One Xiaomi headphone does not work: reasons and 10 proven ways to fix

You've turned on your favorite playlist, but the sound comes from only one Xiaomi headphone? This problem is familiar to many owners of both wired and wireless models, from the budget Redmi AirDots to the flagship Xiaomi Buds 4 Pro. The reasons can be very different from the banal clogging of the speaker to serious hardware malfunctions. But in 80% of cases, the earphone manages to "resuscitate" yourself without the help of a service center.

In this article, we’ll look at all the possible reasons why a single Xiaomi headphone might be silent or make distorted sounds, and give step-by-step diagnostic and repair instructions. You'll learn how to tell a software failure from a physical failure, what settings to check first, and when to actually carry the device to the workshop. ANC (Active noise cancellation – they are more likely to suffer from problems with sound due to design features.

Before you start repairing, answer two key questions: 1. Did the problem appear suddenly or after a specific event (fall, firmware updates, contact with water)? 2. Does the earpiece completely remain silent, make quiet sounds or work with distortions?

The answers will help narrow down the possible causes and save time.

1. Checking the basic settings: why the headphone can "muffle" software

Most often, the problem isn't with the hardware, but with the wrong settings on your smartphone or the headphones themselves, and start with these steps, which take less than a minute, but 30 percent of the time, they solve the problem right away.

The first thing you need to do is make sure that the sound is not turned off at the system level, and on Android, this is a Mono Sound function (sometimes called Sound Balance), which can be activated by accident when you plug in your headphones.

• 📱 On your smartphone: go to Settings → Special facilities → Rumor → Mono Sound and Turn Off the Option if it is Active.
• 🎧 In the headphone app: for Xiaomi models Buds/Redmi Open Mi Earphones (or Xiaomi Earbuds) and check your sound balance settings.
• 🔊 On sound sources: If you connect to a PC or laptop, check the sound settings in the control panel (sometimes one channel can be manually disabled).

Another common reason is the failure of synchronization between left and right headphones (relevant to the TWS-- Try the models:

1. Return both headphones to the case and close the lid for 10 seconds.
2. Get them out and wait for the automatic connection.
3. If the sound is not restored, manually turn off the headphones in Bluetooth Settings and connect again.

Diagnosis of physical damage: when iron is to blame

If the software settings are fine, but one earbud still doesn't work, it's time to check the hardware.

• 🔍 Wire models: Check the cable for fractures (especially at the base of the plug and near the earpiece), bruises or bare wires. Often the cliff occurs inside the strap - try to bend the cable carefully in different places, listening to if there is a sound.
• 💧 Moisture traces: If the earphone has been in contact with water, look for contact oxidation (green coating) or corrosion on the connectors. Even after the moisture has dried, it can cause a short circuit.
• 🔊 Speaker and grid: point a flashlight into the speaker's grille - if you see a buildup of dirt or earwax, this can block the sound.

For wireless models (Xiaomi AirDots, Buds) pay special attention to:

• 🔋 Charging contacts: dirt or oxidation on the "legs" of the headphone and in the case can disrupt power and synchronization.
• 📶 Bluetooth antenna: If the headphone fell, the internal communication module could be damaged.

Critical: If Xiaomi’s headphone stopped working after a fall from a height or a heavy impact, there is a 90% probability that the speaker or circuit board is damaged, in which case self-repair is impossible – you need to replace components in the service center.

3.Brushing headphones: how earwax and dirt kill sound

One of the most underappreciated causes of a broken earphone is a clogging speaker, and earwax, dust, and even fibers from clothing can accumulate under the grid, blocking sound waves, while the earphone can work at low frequencies (basses are heard), but high sounds (voice, guitar) disappear.

How to clean Xiaomi headphones without the risk of damaging them:

Remove large debris with a soft brush (for example, for makeup)|

Use a plastic toothpick wrapped with a wet napkin to clean the grille|

For persistent contaminants, apply 1 drop of hydrogen peroxide (3%) to a cotton swab and gently wipe the mesh|

Don’t blow into the speaker with your mouth – it can damage the membrane |

After cleaning, allow the headphones to dry for 10-15 minutes.-->

For wireless models (AirDots, Buds), cleaning is especially important, as their compact design contributes to the accumulation of dirt. If the sound does not recover after cleaning, try blowing the speaker with compressed air (for example, a can of keyboard cleaning), holding it at a distance of 5-7 cm.

⚠️ Warning: Never use sharp metal objects (needles, knives) to clean, as they can pierce the speaker membrane, and avoid aggressive solvents (acetone, high-concentration alcohol) that destroy plastic and rubber seals.

4.Reset and flash: When Xiaomi headphones "glutch"

If one Xiaomi earphone is plugged in but doesn’t make sound, the problem could be firmware or sync failure, especially for models with ANC (Xiaomi Buds 3 Pro, FlipBuds Pro), where firmware controls microphones and speakers.

How to perform reset and update:

1. Hard reset: For Redmi AirDots: press and hold the touchpad on both headphones for 15 seconds until the indicators flash red. For Xiaomi Buds: put the headphones in the case, then hold the button on the case for 10 seconds (the indicator turns white).

Firmware update:

Mi Earphones

Headphone settings → Software update

Reconnect:

Bluetooth devices

If the sound is completely gone after the update, it's possible that the firmware is not installed correctly.

• Try rolling back the firmware through the app (if there is an option).
• Contact Xiaomi support – they can provide the original firmware file for manual installation.

💡

If Xiaomi headphones after the update began to quickly discharge or spontaneously disconnect, try to reset them and not update the firmware for a week - sometimes come out "raw" versions of the software, which are later fixed.

5. Bluetooth problems: why one earphone is turned off

Xiaomi wireless headphones often suffer from unstable Bluetooth connections, especially if used with non-original devices (such as an iPhone or laptop).

• One earphone is connected, but after a few seconds it turns off.
• The sound is interrupted or delayed.
• The headphone is defined by the phone, but does not reproduce sound.

How to fix it:

If the problem persists, try connecting your headphones to another device (tablet, PC) if they work normally, the problem is in your smartphone's Bluetooth module, which will help:

• 📱 Reset network settings on the phone (Settings) → System system → Reset → Reset Wi-Fi, mobile network and Bluetooth).
• 🔄 Updating the firmware of the smartphone to the latest version.

6. Repair in the service vs. self-replacement: when it is worth carrying to the workshop

If all the previous methods didn't work, it's probably a hardware problem, and here are some signs you should contact a service center:

• 🔊 The speaker emits wheezing or crackling even after cleaning - this indicates damage to the membrane.
• 🔋 The headphone does not charge (the indicator does not burn, despite clean contacts).
• 💥 After a fall or impact, the sound disappeared abruptly - it is possible to peel off the wire or crack on the board.
• 📡 Bluetooth module is not defined by any device.

The cost of repairs in official Xiaomi services (for 2026):

For models older than 2 years, repairs can be unprofitable - it is cheaper to buy new headphones. Exception: flagship models (Xiaomi Buds 4 Pro, FlipBuds Pro), where replacing the speaker or board costs 30-50% of the cost of the device.

⚠️ Note: If Xiaomi headphones are warranty, do not open them yourself - this will void warranty obligations. Official service centers are in all major cities (list on the website). mi.com/ru/service).

💡

Before visiting the service, make a backup copy of the headphone settings (if they are saved in the application) and check the checks / warranty card - without them, repairs can be paid even during the warranty period.

7. Alternative ways of using: what to do if you can not fix

If repair is not possible or feasible, but the second headphone is in good condition, you can adapt it for later use.

• 🎧 As a mono-earphone: many Xiaomi models (like Redmi AirDots 3) support mono-mode work. Just put a non-working earpiece in your case and use a serviceable one.
• 🔊 As a microphone: if the speaker is silent but the microphone is working, the headphone can be connected to a PC for calls (in Windows Sound Settings, select it as an input device).
• 🔋 Spare parts donor: If both earbuds are broken, but each has a different part (for example, one has a speaker, the other has a battery), you can try combining them into one working unit.

For creative tasks, a working headphone can be turned into:

• 🎤 Portable microphone for recording podcasts (using Bluetooth adapter) → 3.5 mm).
• 📻 Remote speaker for notifications (e.g., connect to Xiaomi Smart Home for motion alerts).

If you decide to buy new headphones, pay attention to models with moisture protection (for example, Xiaomi Buds 4 Pro with IP54) and a 2+ year warranty - this will reduce the risk of re-breaking.
