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

Why Xiaomi Redmi Headphones Have a Quiet Sound and How to Fix It

You plugged your headphones into a Xiaomi Redmi, turned on your favorite track, and the sound is barely discernible even at maximum volume? The problem is familiar to many smartphone owners of this line. The reasons may lie in the software limitations of MIUI, and in the hardware features of a particular model, from the Redmi Note 10 to the Redmi 12.

In this article, we will look at 8 proven ways to amplify sound, from basic settings to hidden engineering menu features and third-party utilities. It is important to understand that some methods require caution: exceeding the safe volume level can damage headphone speakers or hearing. So before experimenting, check whether the quiet sound is due to a polluted 3.5 mm connector (if any) or a malfunction of the headphones themselves.

Let’s start with the simplest solutions that do not require superuser rights or install additional software.

1. Check basic volume settings in MIUI

Often the problem is with the wrong set of sound parameters, and MIUI has separate regulators for media, notifications and alarms, which are easily confused.

• 🔊 Open the Quick Settings Panel (swipe down from the top edge of the screen) and make sure the volume slider is set to maximum. ⚙️ next to the slider to go to the advanced settings.
• 🎵 Go to Settings. → Sound and vibration → Loudness. Check here that Multimedia (for music and video) is at least 80%.
• 🎧 If you use Bluetooth headphones, make sure that the Settings menu is in place. → Connected devices selected profile A2DP (for high-quality sound, not for HFP (call-in).

In Redmi models with a 3.5 mm connector (for example, Redmi Note 8 Pro or Redmi 9A), check whether the Safe Sound mode is activated in the headphone settings - it automatically lowers the volume during prolonged listening.

⚠️ Warning: If the sound is completely gone after the headphones are connected, try cleaning the jack of dust with a wooden toothpick (not metal!). In 30% of cases, the problem is solved by mechanical cleaning.

2. Disable volume restrictions in the developer settings

By default, MIUI limits the maximum volume to protect hearing, and you can remove these limits through the developer menu.

1. Activate Developer Mode: Go to Settings → About Phone and 7 times click on the MIUI Version. a notification will appear "You became a developer".
2. Go back to the basic settings and open a new Developer section (usually at the bottom of the list).
3. Find the option Disable absolute volume and activate it, which will allow you to separately adjust the volume on your smartphone and headphones.
4. Below, find the volume limit for headphones and turn it off.

After this, the maximum volume will increase by 15-20%, but be careful: prolonged listening at high volume can lead to distortion of the sound or damage to the speakers.

Check the current version of MIUI (Settings → About Phone)

Activate the Developer Mode

Back up your audio settings (Settings → System → Backup)

Charge your phone at least 50%-->

3.Using an engineering menu to fine-tune the sound

The Engineering Mode allows you to change the parameters of the sound system at a low level, which is suitable for advanced users, since incorrect settings can lead to failures.

Instructions for Xiaomi Redmi:

1. Open the Phone app and enter the code: ##36446337## This will open the engineering menu (some firmware may require code ##4636##).
2. Go to the Hardware Testing → Audio section.
3. Select Headset Mode (for wired headphones) or Headset Bluetooth.
4. In the Value field for Max Vol or Media Volume, increase the value from 100 to 120-140 (not higher!).
5. Save the settings and restart the phone.

⚠️ Attention: Setting a value above 140 can overload the amplifier and cause the headphone speakers to fail. On the Redmi Note 11 and later, the maximum safe value is 130.

4. Installation of third-party equalizers and sound amplifiers

If standard methods don't work, try specialized applications that not only amplify the sound, but also improve the sound quality with an equalizer.

To install ViPER4Android (the most powerful tool) follow the following steps:

1. Download the latest version from the official website or XDA Developers.
2. Install. APK-file and reload the phone.
3. Open the app, go to Driver Status and activate the driver.
4. In the Master Limiter section, increase the value to +3-5 dB (not higher!).

5. Adjust audio via ADB (no root)

If you don't have superuser rights, but you have a computer, you can use ADB (Android Debug Bridge) to change the system settings of the sound, which works on all Xiaomi Redmis running MIUI 12-14.

Instructions:

1. Install ADB Tools on your PC.
2. Turn on the phone debugging over USB (Settings → For developers).
3. Connect your phone to your PC and type in the command line: adb shell settings put global volume_steps 30 This increases the number of volume control steps with 15 before 30, allowing you to adjust the level more accurately.
4. To increase the volume, use the command: adb shell settings put global volume_music_speaker_scale 1.5 (significance 1.5 louden 50%; maximum-safety — 2.0).

⚠️ Attention: Teams ADB Temporary - after restarting the phone, the settings will reset. To make the changes permanent, use the task in Automate or Tasker to automatically execute commands when the device is turned on.

💡

ADB-commands are the safest way to amplify sound without root, but they don’t work on some custom firmware (e.g. Pixel Experience).

6. Hardware solutions: cleaning the connector and replacing headphones

If the software methods didn't work, the problem might be the physical connection.

• 🔌 Connector. 3.5 mm: Blow it with compressed air (a tank for cleaning equipment) or gently brush it with a toothpick. 9/10 Often dust accumulates, which worsens contact.
• 🔋 Bluetooth headphones: Check the charge level – at a discharge below 20%, many models automatically turn the volume down.
• 🎧 Headphone quality: Cheap models with impedance above 32 ohms can sound quiet on smartphones. For Redmi, headphones with impedance 16-32 ohms are optimal.

If you use USB-C headphones, try connecting them via a USB-C → 3.5 mm adapter. On some Redmi models (for example, the Redmi Note 11 Pro+), the sound through the adapter is louder than when you connect directly.

7. Update firmware and reset sound settings

Sometimes a quiet sound is a result of software errors, and updating MIUI to the latest version can solve the problem:

1. Go to Settings → About the phone → System update.
2. If you have an update, download it and install it, especially for Redmi on MIUI 12.5 and below, as newer versions have sound bugs fixed.
3. After the update, reset the sound settings: Settings → Applications → Application Management → Three dots (menu) → Reset the application settings.

If the problem has occurred after the update, try to roll back to the previous version of MIUI via Fastboot or Recovery.Instructions for a specific model can be found on the Xiaomi EU forum.
