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

You've connected your headphones to the Xiaomi Redmi, but is the sound too quiet? Even at maximum volume, music or video sounds muffled and nothing is heard in noisy environments? The problem is familiar to many smartphone owners in this series — especially on models with MIUI 13/14, where the manufacturer artificially limits the volume to protect hearing. But there are ways to get around these restrictions without harming technology.

In this article, we’ll break down 7 working methods, from basic MIUI settings to hidden engineering menu features and third-party apps. You’ll learn how to turn up the volume in wired and wireless headphones (including Redmi Buds), why the sound can be quiet initially, and how to avoid distortions when amplified. All instructions are tested on current models: Redmi Note 12 Pro+, Redmi A2+, Redmi 10C and others.

⚠️ Important: Before changing system settings, check if the quiet sound is due to contamination of the 3.5 mm connector (for wired headphones) or a malfunction of the Bluetooth module (for wireless.

1. Check basic volume settings in MIUI

Before you resort to radical methods, make sure you tune the sound in the system correctly. MIUI has separate regulators for media, calls and alarms - they are easy to confuse.

Open Settings → Sound and vibration and follow the following steps:

• 🔊 Turn off Safe Volume (if active) This feature automatically lowers volume after a long listening period.
• 🎧 Make sure your headphones are selected in the Output Devices section (not the phone speaker).
• 🔄 Check if Do Not Disturb or Vibration is activated in quick settings (swipe down from the top edge of the screen).
• 📱 Restart your smartphone – sometimes the audio settings are reset after the update MIUI.

If the volume has not changed after this, move to the next section. On Redmi models with a Snapdragon 4 Gen 1 processor (for example, the Note 11 Pro+), an additional volume limit at the chipset level can be triggered - it is bypassed through the engineering menu.

2.Use of uniform gain (EQ) in a standard player

The built-in Mi Music player (or Google Play Music if you use it) has a 10-band equalizer that allows you to artificially amplify the sound at certain frequencies, which does not increase the overall volume, but makes the sound more saturated.

How to set up:

1. Open the player and play any song.
2. Slap the icon. ⚙️ Settings → equalizer.
3. Choose a Bass or Rock preset (they amplify low frequencies, which subjectively makes the sound louder).
4. Manually lift sliders on 100 Hz, 200 Hz and 1 kHz on +3–+5 dB.

🔹 Tip: If your player does not have an equalizer, install Poweramp or VLC — They have advanced sound settings, including pre-amplification (Pre-Amp) to +10 dB.

💡

To make equalizer changes applicable to all apps (YouTube, games, social media), use the Wavelet app from Google Play, which works at the system level and adjusts sound globally.

3. Activation of the "For headphones" mode in MIUI

MIUI 12-14 has a hidden option called Headphone Mode that optimizes the sound for a specific device, a feature not available on all Redmi models, but it’s worth checking out.

Instructions:

1. Connect the headphones to your smartphone.
2. Go to Settings → Sound and vibration → Sound quality.
3. If there is a Mode for headphones - activate it and select the type of your headphones (Intrachannel, Overhead, etc.).
4. Reboot the phone.

📌 Note: Some firmware uses this mode as Dolby Atmos or Hi-Fi Audio, and if you don't have an option, your Redmi model doesn't support it at the software level.

4. Change of parameters in the engineering menu (MTK/Qualcomm)

If standard methods don't work, you can manually change the volume limits through the engineering menu, which works on all Redmis, but requires caution - incorrect settings can cause sound distortion or even damage to the earphone speakers.

🔧 Instructions for Qualcomm processors (Snapdragon):

1. Open the Phone app and enter the combination: ##36446337###
2. Go to Hardware Testing → Audio → Headset Mode.
3. Find the settings: Headset Max Vol – set 150-160 (by default 80-100); Headset Gain – increase to 5-7 (standard 0-3).

Save the settings and restart the phone.

🔧 Instructions for MediaTek processors (Helio, Dimensity):

1. Enter the phone app: ##4636##
2. Select Hardware Testing → Audio → Headset.
3. Change: Max Vol to 128 (maximum). Type to Class D (if available).

⚠️ Warning: Setting values above 160 for Max Vol or 7 for Gain can cause clipping (sound distortion) and damage your headphones (+10-20 units) and check the sound quality.

Make sure the headphones are connected|Record the initial values of the parameters|Not exceed Max Vol. >160|Reboot your phone after the changes-->

5.Apps for amplifying sound (without root)

If you don't want to go through the system settings, you can use third-party apps that run on top of MIUI and amplify the sound software.

• 🎵 Volume Booster GOODEV — louden +60% free of distortion, supports individual headphone profiles and speaker.
• 🔊 Precise Volume – allows you to set the volume to an accuracy of 1% (instead of the standard 15 steps in the volume). MIUI).
• 🎧 Wavelet - advanced equalizer with auto-tuning for headphones and bass amplifier.
• 📱 SoundAssistant (from Samsung, but runs on Xiaomi) – adds separate regulators for each type of sound.

🔹 How to install and configure:

1. Download one of the apps from Google Play.
2. Open and give access to the sound settings.
3. Activate the Volume Amplifier or Boost Volume option.
4. Adjust the gain level (start with +20% to avoid distortion).

⚠️ Note: Some applications (such as Volume Booster) may conflict with MIUI 14 and cause sound to freeze. If after installation, the headphones start to "wheeze" - delete the program and use an alternative.

6 Unlock hidden options via ADB (for advanced)

If the engineering menu did not give a result, you can unlock additional sound settings through the ADB-This method requires a computer, but it can get around the limitations. MIUI rootless.

🖥️ Step-by-step instruction:

1. Download and install ADB Tools on PC.
2. On the phone, activate Developer Mode (7 times tap the MIUI version in Settings → About the phone).
3. Enable USB debugging in Settings → Additional → For developers.
4. Connect Redmi to your computer and type in the command line: adb shell settings put global volume_steps 30 This command increases the number of volume control steps with 15 before 30, allowing you to adjust the level more accurately.
5. To unlock the maximum volume, use: adb shell settings put global volume_music_speaker_scale 1.5 adb shell settings put global volume_headset_scale 1.8 (significance 1.5 and 1.8 can be increased 2.0, higher!).
6. Reboot the phone.

📌 Note: After update MIUI These settings can reset. To return them, repeat the steps or use the app. ADB AppControl for Automatic Application of Commands.

💡

ADB-commands are the most effective way to turn up the volume without root, but it takes care. volume_scale higher 2.0, Otherwise, you risk damaging your phone’s headphones or speakers.

7. Checking hardware problems

If none of the software methods worked, it might be the hardware that's the problem.

• 🔌 3.5mm connector: Check it for contamination or mechanical damage. Try connecting the headphones to another device -- if the sound is as quiet, the problem is with them.
• 📶 Bluetooth module: On Redmi models with Snapdragon 4xx (Like Redmi. 9A) It could be a weak Bluetooth signal, see if you're losing communication with your headphones over 5 meters away.
• 🔋 Battery: With a discharge below 15%, some Xiaomi models automatically turn down the volume to save energy.
• 🛠️ Headphone speakers: If the sound is quiet in only one ear, maybe the speaker grid is clogged. Clean it with a soft brush or compressed air.

🔧 Diagnosis through a sound test:

1. Enter the phone app: ##4636##
2. Select Hardware Testing → Audio → Headset Test.
3. If Fail is displayed in the Result column, this indicates a malfunction of the connector or headphones.

⚠️ If all tests fail: Contact the service center. On Redmi models older than 2 years, the sound chip often fails (for example, Realtek). ALC5640), and its replacement costs 1,500-3,000 ₽.
