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

You bought a Xiaomi Redmi headphone, but the sound is too quiet, even at maximum volume? The problem is familiar to many owners of budget and mid-budget models - from Redmi AirDots to Redmi Buds 4 Pro. The reasons can lie in both the software limitations of MIUI and the hardware features of the headphones themselves. In this article, we will discuss 8 working ways to increase the volume, including hidden settings, engineering menus and safe workarounds.

It's important to understand that quiet sound is not always a defect. Manufacturers specifically limit the maximum volume to protect users' hearing (European regulations EN 50332-2 limit the sound level to 85 dB). However, if you are sure that the headphones are working and the sound is objectively weak, our instructions will help to unlock their potential.

1. Check basic volume settings in MIUI

Before you dig deep, make sure that the problem is not the trivial settings. MIUI has separate volume controls for media, calls and notifications — they're easy to confuse.

• 🔊 Volume Controller: Press the physical volume button on your smartphone and make sure the Multimedia slider (not the Call) is set to maximum.
• 🎧 Individual volume for headphones: Connect the headphones and adjust the volume again - sometimes the system resets the settings the first time you connect.
• 🔇 Do Not Disturb Mode: Check if it is activated in the notification curtain or on schedule (Settings) → Sound and vibration → Don't disturb).
• 🔄 Reboot device: Banal, but often helps – especially if the headphones are connected over Bluetooth and the sound “hangs” at a low level.

If you keep the sound quiet after this manipulation, move on to the next section. Note that some Redmi models (like the Redmi Note 10 Pro) have a separate "Hearphone Amplifier" item in the audio settings, which can turn on +10-15% of the volume.

2. Equalizer and sound effects setup

MIUI has a built-in system equalizer that can artificially raise volume by amplifying certain frequencies, which doesn't increase the actual power of the sound, but subjectively makes it louder.

1. Open Settings → Sound and vibration → Equator.
2. Select the user profile (or bass if you want to amplify the low frequencies).
3. Lift the sliders 100 Hz and 300 Hz (this will add "volume" to the sound) and slightly increase 1 kHz (average frequencies responsible for vocals).
4. Save the preset under the name, for example, Max Volume.

For owners of Redmi Buds 4 Pro and other models with support for LDAC or AAC, additional codec settings are also available. Go to Bluetooth Settings → Headphones → Sound Quality and select "Best Quality" (if available).This can improve sound detail, but does not always affect volume.

💡

If the built-in equalizer seems weak, try third-party apps like Wavelet (with ViPER4Android support) or Poweramp Equalizer, which allow you to fine-tune the sound and even bypass some of the limitations of MIUI.

3. Engineering menu: hidden volume settings

Xiaomi smartphones have a hidden engineering menu (Engineer Mode) where you can manually increase the maximum volume for headphones, a method that works on most Redmi models, but requires caution - incorrect settings can lead to distortion of the sound.

Instructions for entering the engineering menu:

1. Open the Phone app and enter the combination: ##36446337###
2. Select Hardware Testing → Audio → Headset Mode.
3. In the Max Vol section, increase the value from 150 to 160 (do not put higher – risk of distortion!).
4. Save the settings and restart the smartphone.

⚠️ Note: After changing the settings in the engineering menu, test the sound on different tracks. If there are wheezing or distortions, return the Max Vol value back to 150.

4. circumvention of restrictions through ADB (for advanced)

If standard methods don't work, you can remove software volume limits through ADB (Android Debug Bridge), which requires connecting your smartphone to your computer and basic command line knowledge, but has the most noticeable effect.

Step-by-step:

1. Enable USB Debugging in the Developer Settings (Settings → About Phone → MIUI Version – Press 7 times, then return to Additional → For Developers).
2. Connect your smartphone to your PC, install it ADB-Drivers and open the command line in the folder with the platform-tools.
3. Enter the command to check the connection: Adb devices should appear the name of your device.
4. Execute the command to remove volume limit: adb shell settings put global volume_steps 30 This increases the number of volume control "steps" from standard 15 before 30, allowing you to adjust the level more accurately.
5. To fully remove restrictions (at your own risk!) use: adb shell settings put global absolute_volume_enabled 1 Warning: This command can cause sound distortion at maximum volume!

After you've done the commands, restart your smartphone, and you'll notice the effect immediately, the volume control will be smoother, and the maximum level will increase by 20-30%. If the sound starts to wheez, return the settings back with the command:

adb shell settings delete global absolute_volume_enabled

💡

ADB-It's the most effective method, but it's also the riskiest, and you should only use it if other methods haven't worked, and remember, long periods of listening to music at maximum volume can be bad for your hearing!

5. Problems with Bluetooth headphones: how to amplify the signal

If you have Xiaomi Redmi wireless headphones (like Redmi AirDots 3 or Redmi Buds 4 Active), the problem may not be the volume of the smartphone itself, but the quality of the Bluetooth connection. A weak signal leads to loss of data packets and, as a result, to a quiet or intermittent sound.

What can be done:

• 📶 Change the codec: In Bluetooth settings (Settings) → Connected devices → Headphones → Codec) select AAC instead. AAC Provides better sound quality with a stable connection.
• 🔄 Reconnect your headphones: Remove them from the list of associated devices and reconnect them. Sometimes it helps to reset the headphone settings (press the power button for 10 seconds).
• 📱 Turn off power saving for Bluetooth: Go to Settings → Battery → Energy saving applications and add "Bluetooth" to exceptions.
• 🛡️ Check for interference: Other wireless devices (Wi-Fi routers, microwaves) may cause interference. Try using headphones elsewhere.

For models with Bluetooth 5.2+ support (such as Redmi Buds 4 Pro), the dual connection feature is also available, and disable it if you don’t use it, which can improve connection stability and, as a result, volume.

6. Resetting headphones and smartphone settings

If all previous methods failed, the problem could be a software failure, either in the smartphone or in the headphones themselves, in which case the reset will help.

For the smartphone:

1. Go to Settings → System → Resetting settings.
2. Select Network Settings Reset (this will delete all stored Wi-Fi and Bluetooth devices, but will not affect personal data).
3. After resetting, restart your smartphone and connect the headphones again.

For wireless headphones:

• Put the headphones in the case and close the lid.
• Press and hold the button on the case (usually one) for 10-15 seconds until the indicator flashes red/white.
• Get the headphones out of the case - they will automatically reset and will be ready for a new pairing.

⚠️ Note: If after reset, the headphones stopped connecting or make strange sounds (squeaking, noise), this may indicate a hardware malfunction.In this case, contact the Xiaomi service center - self-repair can deprive you of warranty.

Are the earphones clean (no dirt in the speakers)?

Is the problem manifesting on multiple devices?

Is the cable (for wired models) not damaged?

Is the smartphone and headphones updated?

7. Third-party applications for sound amplification

If the built-in MIUI tools don't work, you can use third-party apps, and they work on two principles:

1. Software amplification – increase the volume due to sound processing algorithms (can lead to distortions).
2. Bypass system limitations – change the parameters of Android, as in the method with ADB, but through the graphical interface.

Top.-3 tested applications:

• 🎛️ Volume Booster is a simple booster with presets for different types of headphones.
• 🎧 ViPER4Android — It's an advanced sound processor with equalizer and effects, it requires manual tuning, but it gives you better results.
• 🔊 Precise Volume – allows you to adjust the volume more delicately (up to 100 steps instead of the standard 15 steps).

⚠️ Attention: Apps like Volume Booster can turn up the volume above safe limits. Prolonged listening to music above 85 dB leads to irreversible hearing loss! Use them carefully and only when necessary.

To install ViPER4Android, you will need:

1. Download the latest version from XDA Developers.
2. Install the ViPER4Android FX driver via Magisk (root rights required).
3. In the application settings, select the Headphones profile and activate Master Limiter (increases maximum volume).

8. Hardware causes of silent sound and their elimination

If the software methods didn't work, the problem could be hardware, and here are the most common reasons and ways to diagnose them:

To check for hardware problems:

1. Connect your headphones to another device (PC, other smartphone), and if the sound is still quiet, the problem is with the headphones.
2. Try other headphones with your smartphone, and if they play loud, the problem is your headphones.
3. Check the sound through the speakers on your smartphone. If it's quiet, it's possible that the sound chip is faulty.

If the diagnosis showed a hardware malfunction, and the warranty is still valid, contact the official Xiaomi service. Self-repair of headphones (especially wireless) is often unprofitable due to the complexity of their design.

💡

Before visiting the service, make a backup of your smartphone data - sometimes a full reset is required to diagnose the sound.
