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

You turned on your favorite music at full volume, but the sound in Xiaomi Redmi headphones is still too quiet? This problem is familiar to many owners of the brand’s smartphones – especially when using budget models of the Redmi Note, Redmi A or POCO series. The reasons can lie in both the software limitations of the MIUI and the hardware features of the audio chip.

In this article, we will look at 7 proven ways to turn up the volume in headphones, from basic Android settings to hidden options in the engineering menu. Importantly, some methods require caution, as improper actions can damage the earphone speakers or distort the sound, we will explain the risks in detail and give recommendations on how to avoid them.

1. Check basic volume settings on Xiaomi Redmi

Before you resort to radical measures, make sure that the problem is not in the trivial settings. Xiaomi smartphones have separate volume controls for multimedia, calls and alarms – they are easy to confuse.

How to check:

• 🔊 Press the physical volume button on the side panel of the smartphone → Make sure the slider is at maximum.
• 🎵 Open the player (for example, Mi Music or YouTube Music) → Swipe down from the top edge of the screen → Check if Do Not Disturb or Quiet mode is activated.
• 🔧 Go to Settings. → Sound and vibration → Loudness → Set maximum values for all categories.

If the sound is still quiet after this manipulation, the problem goes deeper, and it's possible that your Redmi has activated security restrictions, which we'll look at in the next section.

2. Turning off volume restrictions in MIUI

MIUI blocks the safe volume level (usually 80-85% of maximum) by default to protect the user's hearing, which can be removed, but remember: long-term listening to music at high volume can lead to irreversible hearing loss.

Instructions for deactivating the limit:

1. Open the Settings. → Sound and vibration.
2. Slip on Safe Volume (or Volume Limitation in older versions of MIUI).
3. Select Disable or move the slider to the right.
4. Confirm the action by pressing OK in the warning window.

Then check the volume in the headphones. If the changes are minor, proceed to the next method.

💡

On some Xiaomi Redmi models (such as the Redmi Note 10 Pro), the volume limit is reset after rebooting. To avoid this, turn off automatic settings updates in Settings → About Phone → System Update

3.Use of the Engineering Menu (MTK/Qualcomm)

If standard settings do not help, you can turn to the engineering menu - the hidden section of Android, where advanced audio system options are available.The method works on Xiaomi Redmi smartphones with MediaTek chips (Redmi 9/10/Note 11 series) and Qualcomm Snapdragon (POCO X3/Redmi Note 12 series).

For MediaTek:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #4636## for older versions).
3. Go to the Hardware Testing → Audio section.
4. Select Headset Mode and increase the Max Vol value (e.g., from 140 to 160).

For Qualcomm Snapdragon:

1. Enter the phone: #8999##.
2. Select Headset → increase the Volume and Gain settings by 10-15 units.

Check the processor model in Settings → About the phone

Warning: Incorrect changes to the engineering menu can damage the audio chip or completely lose sound.If you're not sure what you're doing, skip this method.

4. Apps to amplify sound: top-3 decision

If you don't want to go through the settings, you can use third-party apps, and we tested dozens of utilities and selected the 3 most effective for Xiaomi Redmi:

How to use:

1. Install the selected application from Google Play.
2. Open it and give access to the sound settings.
3. Activate amplification mode (for example, in Volume Booster, click Boost).
4. Connect the headphones and check the result.

Importantly, apps can't overcome the hardware limitations of a smartphone. If the sound is still quiet, the problem could be with the headphones themselves or the audio jack.

5. Checking headphones and audio jack

Low volume isn't always about settings on the phone, often because of a dirty connector or a faulty headphone.

• 🔍 Inspect the 3.5mm connector (or USB-C) If necessary, clean it with a dry toothbrush or compressed air.
• 🎧 Connect your headphones to another device (like a laptop or other smartphone) If the sound is the same quiet, the headphones are a problem.
• 🔄 Try other headphones with your Xiaomi Redmi.If the volume goes up - old headphones are out of order.

If the jack or headphones are damaged, contact the service center. Self-repair can exacerbate the problem.

6. Update firmware and reset settings

Sometimes the low volume in the headphones is associated with software bugs in the current version of MIUI. The solution is to update the firmware or reset the sound settings to factory.

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download it and install it.

How to reset the sound settings:

1. Open the Settings. → Sound and vibration.
2. Slip on three points in the upper right corner → Reset settings.
3. Confirm the action.

After resetting, all custom audio settings (including equalizer) will be deleted, but this can solve the quiet sound problem.

💡

If the sound is gone after the firmware update, reset to factory settings via Settings → About Phone → Reset. Pre-reverse the data!

7 Radical methods: root access and modification of system files

If none of the above methods worked, the last option is to get root rights and edit the system files that control volume, which is only suitable for advanced users, because:

• 🚨 Cancellation of warranty on Xiaomi Redmi.
• 🛠️ May lead to a blink (complete inoperability) of the device.
• 🔒 Requires unlocking the bootloader through the Mi Unlock Tool.

If you are willing to take a risk, follow the instructions:

1. Unlock the bootloader through the official Xiaomi tool (link).
2. Install a custom recovery (TWRP) for your model.
3. Please use Magisk to obtain root rights.
4. With a root-access file manager (such as Root Explorer) open the file. /system/etc/mixer_paths.xml.
5. Find the rows with the headphone parameters and increase the rxX digital volume (where X is the channel number).
6. Save the changes and restart the smartphone.

Warning: Incorrect editing of system files can lead to loss of sound forever.We recommend you to create a full firmware backup through TWRP beforehand.

💡

Before you get root rights, check if your Xiaomi Redmi model has modified firmware with amplified sound (such as Pixel Experience or LineageOS) ready-made, which is safer than manual file editing.
