What to do if Xiaomi headphones have a very quiet sound: the complete guide

You've turned on your favorite track, but instead of a powerful bass, you hear a barely discernible whisper? The problem of quiet sound in Xiaomi headphones is more common than you think, and it can be caused by both software limitations of MIUI and hardware problems, from a contaminated connector to worn-out speakers. In this article, we will examine all possible causes and ways to eliminate them, from simple smartphone settings to diagnosing the headphones themselves.

Xiaomi devices have built-in volume limiters that work when you plug in uncertified accessories, for example, if you use Sony or Samsung headphones, the system can automatically turn down the volume for fear of damaging the speakers, but that's just one of the reasons. Next, Step-by-step, with illustrations, comparison tables and expert advice to help bring the sound back to its former volume.

1. Check basic volume settings on a smartphone

Before you take apart your headphones or search for hidden menus, make sure the problem isn't the obvious. Let's start by checking the standard volume controllers in MIUI:

• 🔊 Physical buttons: Press the volume button on the sidebar of the smartphone. Sometimes users accidentally reduce the sound without noticing it.
• 📱 Notification Panel: Swipe your finger from top to bottom and make sure the volume slider for multimedia doesn’t move to left.
• 🔇 Do Not Disturb: Check in the same notification panel to see if the mode is activated DND (cross-bell icon).

If the sound is still quiet after this manipulation, move on to the next step. Note: some Xiaomi models (such as the Redmi Note 10 Pro or POCO X3 Pro) have a separate volume controller for the headphones. To find it, plug the headphones and open the notification panel again - an additional slider should appear.

2.Resetting volume restrictions in MIUI

MIUI by default limits the maximum volume to protect hearing, and this restriction can be removed through hidden settings:

1. Open the Settings app.
2. Go to the section Sound and vibration.
3. Slip on Volume (or Media Volume on new versions).
4. In the upper right corner, press three dots (⋮) and select Turn off the safe volume level.

If this is not the case, try an alternative method:

1. Enable Developer Mode: Go to Settings → About Phone → MIUI Version and tap it 7 times.


2. Return to Settings → Additional → For developers.




3. Find the option to turn off absolute volume and activate it.




4. Reboot the smartphone.

These actions will relieve software limitations, but be careful: long-term listening to music at maximum volume can damage your headphones or hearing.

💡

If the sound is still quiet after resetting the restrictions, try connecting the headphones to another device (laptop or tablet), if the problem persists, the headphones themselves are defective.

3. Clean the 3.5mm connector or USB-C

One of the most common causes of silent sound is contamination of the audio jack, and dust, pile, or contact oxidation can impair signal transmission.

• 🕯️ Use a toothpick: gently, without pressing, walk through the inner contacts of the connector. Do not use metal objects!
• 💨 Compressed air: A spray of compressed air (such as cleaning keyboards) will help blow dust out of deep areas.
• 🔌 Alcohol wipes: to remove oxidation, wipe the contacts with a napkin dipped in isopropyl alcohol (at least 70%).

For USB-C devices (such as Xiaomi 11T or POCO F4), the cleaning process is similar, but be especially careful: it is easier to damage the contacts in this connector. If the sound does not improve after cleaning, try connecting the headphones via Bluetooth - this will help to localize the problem.

4. Checking headphones for hardware malfunctions

If all the software settings are correct and the connector is clean, the problem may lie in the headphones themselves.

Use a multimeter to diagnose headphone resistance. Connect its probes to the plug contacts (Tip is left, Ring is right, Sleeve is general). Normal values for most Xiaomi models (for example, Mi Basic or Mi Dual Driver) are 16-32 Ohms. If readings are above 100 Ohms, the speakers are faulty.

💡

If Xiaomi headphones are guaranteed, do not disassemble them yourself! Contact an authorized service center - repair under warranty is possible only if the seals are saved.

5. Equalizer and sound effects setup

MIUI has an integrated equalizer that can inadvertently turn down the volume at certain frequencies to adjust it:

1. Open Settings → Sound and vibration → Equator.
2. Choose a preset (like Bass or Rock) or create your profile.
3. Increase the sliders at 60Hz (bass) and 1-3kHz (medium frequencies), which most affect the perceived volume.

Also check the sound effects settings:

• 🎧 Mi Sound Enhancer: In the same audio settings, turn off the option if it's active - sometimes it distorts the sound.
• 🔊 Dolby Atmos: If your model supports this technology (e.g. Xiaomi 12 Pro), try incorporating it into Settings → Display and sound → Dolby Atmos.

If you use third-party players (like Poweramp or VLC), check their equalizer settings – they can overlap the system.

6. Problems with Bluetooth headphones (TWS)

For Xiaomi wireless headphones (such as the Redmi Buds 3 Pro or Xiaomi Air 2 SE), the quiet sound can be attributed to:

• 📶 Weak signal: if there are many obstacles between the smartphone and headphones (walls, furniture), the communication deteriorates, and the sound becomes quieter.
• 🔋 Low charge: At a charge level below 20%, some models automatically turn down the volume.
• 🔄 Bluetooth Codecs: Codecs can be selected by default SBC, It's a compressor. Try switching to a sound. AAC or.

To change the codec:

1. Put the headphones on.
2. Open the Settings. → Connected devices → Settings (⚙️) near your headphones.
3. Choose the Audio Codec and try other options.

Critical: on some Xiaomi models, the aptX codec is only supported when connected to devices with Android 10+ and Qualcomm chipset (for example, the Snapdragon 732G in the Redmi Note 10 Pro).If your smartphone is on MediaTek (for example, POCO M3), this codec may not be available.

Check the charge level of the headphones.

Make sure the distance to the smartphone is no more than 10 meters

Reconnect the headphones (forget the device and pair again)

Update the headphone firmware through the Mi Home app (if supported)

7. Update firmware and reset settings

Sometimes, a quiet sound is a consequence of software bugs in MIUI.

1. Update the system: Settings → About the phone → System update.
2. If there are no updates, reset the audio settings: 1. Open Settings → Applications → Application Management. 2. Find Media Storage and press Storage → Clear Data. 3. Reboot your smartphone.

If the problem has occurred after the update, try to roll back to the previous version of MIUI via Fastboot (the instructions are available on the XDA Developers forum).

💡

Before resetting settings, back up important data through Settings → Additional → Backup and Reset.

8.When to contact the service center

If all of these methods fail, the problem may be hardware.

• 🔧 Silent sound is observed on all devices (smartphone, PC, other phone).
• 🎛️ In headphones, extraneous noises (squeaking, crackling) can be heard, even when the music is turned off.
• 🔌 3.5 mm connector or USB-C shattered and the contacts blackened (oxidized).
• 📱 On the smartphone after falling or getting moisture, the sound in the speaker disappeared (this may indicate damage to the audio chip).

The cost of repairs in authorized centers Xiaomi:

Before visiting the service, check if the warranty period has expired (usually 12 months for smartphones and 6 months for accessories).If Xiaomi headphones are officially purchased, the warranty is valid if you have a check or purchase data in the Mi Account.

💡

Don’t trust repairs to unofficial workshops if your device is warranty! Xiaomi will void the warranty if traces of autopsy are found.
