How to increase the sound in Xiaomi headphones: from standard settings to hidden features

You've connected your headphones to a Xiaomi smartphone, but the sound is too quiet, even at maximum volume? This problem is familiar to many owners of devices on MIUI - especially after system updates or when using budget models. In 80% of cases, the quiet sound is not due to a breakdown, but to software restrictions that can be avoided.

In this article, we will look at 7 proven ways to increase volume, from basic settings to hidden engineering menu features. Importantly, some methods require caution, as excessive amplification of sound can damage headphone speakers or hearing. We will highlight safe and risky options so that you can choose the best one.

Instructions are suitable for all modern Xiaomi, Redmi and POCO smartphones (including Xiaomi 13/14, Redmi Note 12/13, POCO F5/X5). If your model is older than 2018, check the section about updating the firmware - this can solve the problem without additional manipulation.

1. Check the basic settings of MIUI

Before resorting to sophisticated techniques, make sure the problem isn't with standard settings.MIUI often resets audio settings after updates or new devices are connected.

Open Settings → Sound and vibration and do the following:

• 🔊 Check the volume slider, sometimes it's down to Media instead of Headphones.
• 🎧 Turn off Safe Sound: In the Sound Quality section, deactivate Volume Limitation (if any).
• 🔄 Reset the sound settings: at the bottom of the page, click Reset the sound settings - this will return factory settings.
• 📱 Check the sound profile: in the notification curtain, make sure that the "Sound" or "Vibration" mode is selected. + sound, not soundless".

If the volume hasn't changed after this, move on to the next method. On some models (like the Redmi Note 10 Pro), the Sound and Vibration menu has a hidden item called Headphone Amplifier - turn it on if it's available.

2.Use of uniform equalizer (EQ)

MIUI has an equalizer built in that can artificially amplify sound at certain frequencies, which doesn't increase the overall volume, but makes it clearer and louder by correcting it.

How to set up:

1. Open Settings → Sound and vibration → Sound quality → Equalizer.
2. Choose a Bass or Rock preset – they amplify low and medium frequencies, which subjectively increases the volume.
3. Manually lift sliders on 100 Hz, 200 Hz and 1 kHz on +3... +5 dB.
4. Save the settings as a new profile (e.g., “Augmented”).

For more flexibility, use third-party apps like Wavelet or Poweramp Equalizer, which allow you to use the equalizer globally (including YouTube and games), not just in a music player.

💡

If your MIUI version doesn’t have a built-in equalizer, install the Poweramp player – it has its own 10-band EQ with presets.

3. Activation of hidden sound amplifier in the engineering menu

Xiaomi smartphones have a hidden engineering menu where you can turn on the hardware audio amplifier for headphones, which works on most models, but requires caution – incorrect settings can lead to distortion.

Instructions:

1. Open the Phone app and enter the code ##36446337## (some models run ##4636## → Audio information).
2. Go to the Headset section (or Headphones).
3. Find the Headset Gain or Headset Volume setting and set the High or Max value.
4. Save the settings and restart the phone.

If the sound becomes distorted or background noise appears after the change, return the value to Normal. On Qualcomm Snapdragon models (e.g., POCO X3), this method gives a volume increase of up to 30%.

4. Installation of third-party applications to amplify sound

If standard methods don't work, use specialized utilities that work at the system level and can bypass the limitations of MIUI.

Top.-3 tested applications:

To install ViPER4Android on MIUI 13/14, you will need:

1. Install Magisk and ViPER4Android FX module.
2. In the application settings, select the Legacy Mode driver.
3. Activate Master Limiter and raise Pre-Amp to +3...+5 dB.

💡

Apps like Volume Booster can damage headphone dynamics when used at maximum length. Use them only for temporary amplification.

5. Update firmware and reset settings

If the quiet sound appeared after the MIUI update, the problem may be a software bug. Xiaomi regularly releases patches that fix audio problems, so check the relevance of the firmware:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version (if available).
3. After the update, reset the sound settings (Settings → Sound and vibration → Reset).

If the update didn’t work, try resetting all your phone settings to factory:

• 🔄 Settings → The phone. → Resetting settings → Resetting all settings.
• ⚠️ Don’t confuse it with “Reset to factory” – it will delete all data!

On some models (for example, Xiaomi Mi A3) helps flashing to custom software (for example, Pixel Experience), where there are no restrictions MIUI. However, this requires unlocking the bootloader and may deprive you of warranty.

1. Save important files to Google Drive or PC

2. remember logins/passwords from accounts

3. Untie the device from Mi Account (Settings → Xiaomi Account)

4. Charge your phone at least 50%-->

6. Checking hardware problems

If the software methods didn't work, it could be a physical malfunction.

• 🎧 Headphones: test them on another device. If the sound is quiet everywhere, the problem is in the headphones (contaminated connector, cable torn).
• 🔌 3.5mm connector: inspect it for oxidation or damage. Clean with alcohol and cotton wool.
• 📶 Bluetooth headphones: turn them off and reconnect them. In Bluetooth settings, select High audio quality (if any).
• 🔊 Phone speaker: if the sound is quiet and without headphones, it may be clogged with speaker grid (clean with a toothpick).

On Type-C models (such as the Xiaomi 12T), the problem may be with the headphone adapter.

⚠️ Warning: If after connecting the headphones the phone gives an error "Accessories are not supported", do not use them - this can damage the audio chip.

7. Alternative methods (for advanced users)

If you are ready for experiments, try these methods:

• 🛠️ File editing mixer_paths.xml: This file is responsible for volume limits. To change it, you need root rights and a file manager (like Root Explorer: /system/vendor/etc/mixer_paths.xml. Look for lines with headphone and increase the max value by 10–20%.
• 🤖 ADB-commands to unlock volume: Connect your phone to your PC, turn on Debugging USB Adb shell settings put global settings volume_steps 30 This will increase the number of volume steps with 15 before 30, This will allow you to regulate the sound more accurately.
• 🔧 Custom core installation: Cores like FrancoKernel or Kirisakura optimize audio chip performance, requires unlocked bootloader and experience with audio chips. TWRP.

⚠️ Note: Editing system files or using ADB This can lead to a device break (completely inoperable!
