How to increase the volume in headphones on Xiaomi phone: safe and hidden methods

Have you turned on your favorite track at full volume, but the sound in your headphones is still too quiet? Xiaomi smartphones (including Redmi and POCO) often limit the maximum volume through MIUI firmware - this is done to protect your hearing and speakers. However, if you are sure that your headphones can withstand a lot of stress and the current sound level is not satisfied, there are several ways to get around the restrictions.

In this article, we will look at 7 proven methods, from standard MIUI settings to hidden engineering menu features and third-party applications. Importantly, some methods require root rights or may affect the warranty. We will note the risks in each section so that you can choose the safe option.

Before you start, check:

  • ๐Ÿ”Š Clean connector (for wired headphones) โ€“ dust and oxidation of contacts reduce volume.
  • ๐ŸŽง Headphone compatibility โ€“ some models (such as high impedance) are initially quieter on smartphones.
  • ๐Ÿ“ฑ Updates MIUI โ€” Newer versions of the firmware may have additional restrictions.

If the problem is not in the hardware, move on to the settings.

MIUI Sound Settings: What Can Be Changed Without Risks

Let's start with the safest way, the standard MIUI tools, and there are hidden options in the firmware that many users don't notice.

Open Settings โ†’ Sound and vibration and pay attention to the following points:

  • ๐Ÿ”ค Headphone amplification โ€“ includes an additional boost (not available on all models).
  • ๐ŸŽต Mi Sound equalizer โ€“ Adjusting frequencies can subjectively increase volume (e.g., lifting to a higher level). 3-6 keto).
  • ๐Ÿ”‡ Turning off the safe volume level โ€“ uncheck the box in the Security and Warnings section.

Some devices (such as Xiaomi 12T or POCO F4) have a separate Loudness for Media slider in the Quick Settings Panel - pull it up to the end. If it's not there, try installing an alternative notification bar through Settings โ†’ Screen โ†’ Notification Panel.

โš ๏ธ Warning: Turning off the safe volume level can cause distortions at maximum levels, especially in cheap headphones!

2. Engineering menu: hidden volume settings

Xiaomi smartphones have an engineering menu (MTK Engineering Mode or Qualcomm Service Menu) where you can manually turn up the volume for different scenarios, a method that does not require root, but works until the device is restarted.

Instructions for Qualcomm processors (most Redmi/POCO models):

  1. Open the Phone app and type ##4636##.
  2. Select Phone Information โ†’ Select Information Type โ†’ Engineering Mode (MTK).
  3. Go to Hardware Testing โ†’ Audio.
  4. In Headset Mode, find Max Vol options and increase the values by 5-10 units (for example, from 140 to 150).

For MediaTek processors, the path is different:

  1. Enter ##36446337##.
  2. Go to Hardware Testing โ†’ Audio โ†’ Headphone Mode.
  3. Change the Volume and Max Volume settings (do not exceed 160 to avoid distortion).

โš ๏ธ Note: Some options in the engineering menu may be lost after the update MIUI. It is also not recommended to increase the volume of the microphone (Mic Volume) - this will lead to strong noises when calling.

What to do if the engineering menu is not opened?
If the code ##4636## or ##36446337### doesn't work, try: 1. MTK Engineering Mode from Play Market (for MediaTek). 2. ADB-command to unlock the menu (PC required). 3. Check if the menu in your version is removed MIUI (relevant to some global firmware).

3. Apps to amplify sound: top-5 utility

If the standard methods didn't work, you can use third-party applications, and we tested 15 utilities and selected the most effective ones for Xiaomi:

AnnexType of amplifierRoot is required.Ratings.
Volume BoosterProgram boost (up to +20%)โŒ No.4.5/5
Equalizer FXEquator + Pre-amplifierโŒ No.4.7/5
ViPER4AndroidFull sound processingโœ… Yes (for full functionality)4.9/5
Precise VolumeFine tuning of volume stepsโŒ No.4.3/5
Music Volume EQEnhancer + equalizerโŒ No.4.2/5

The most powerful tool is ViPER4Android, but installing it on MIUI requires:

  1. Activate root access (for example, via Magisk).
  2. Install the ViPER4Android FX driver via Magisk Module.
  3. Set up an in-app profile (we recommend starting with ClearAudio+).

ViPER4Android It may conflict with the system DSP-manager MIUI. If after installation the sound disappears, turn off the option "Hardware acceleration" in the settings of the application.

4. Modification of system files (for advanced users)

This is a method that works for those who are willing to work with system files, and it allows you to permanently increase the volume, but requires root rights and data backup.

Instructions for MIUI based on Android 12/13:

  1. Install Root Explorer or FX File Explorer.
  2. Go to /system/vendor/etc/.
  3. Find the file. mixer_paths.xml (or mixer_paths_qrd_skuh.xml for some).
  4. Open the file in the text editor and find the lines: <path name="headphone"> <ctl name="HPHL Volume" value="60" /> <ctl name="HPHR Volume" value="60" />
  5. Increase the value to 80-90 (no more than 100!).
  6. Save the file and restart the phone.

For Android. 10/11 path may differ: /vendor/etc/audio_platform_info.xml. In this file, look for parameters. speaker_gain and headphone_gain.

โš ๏ธ Warning: Incorrect editing of system files can lead to bootloop. Always back up the original file! If the sound disappears after the changes, restore the original version.

๐Ÿ’ก

Before editing system files, check for backups in /system/vendor/etc/backup/. Some MIUI firmware automatically creates them when you update.

5. Hardware solutions: when the problem is not in the settings

If the software methods did not help, the reason may lie in the hardware:

  • ๐Ÿ”Œ Contact oxidation in the 3.5 mm connector (relevant for the Redmi Note 8 Pro, POCO X3 NFC etc.).
  • ๐Ÿ”‹ Weak amplifier in a smartphone (typical for budget models like Redmi) 9A).
  • ๐ŸŽง High impedance headphones (resistance above 32 ohms requires an external amplifier).

How to check:

  1. Connect the headphones to another device โ€“ if the sound is loud, the problem is in the phone.
  2. Try other headphones - if they work louder, it's impedance.
  3. Check the 3.5mm connector for contamination (use a flashlight).

Decisions:

  • ๐Ÿงน Clean the connector with alcohol and cotton swab (do not use metal objects!).
  • ๐Ÿ”Š Buy the outside. DAC/Amplifier (e.g. Xiaomi) USB-C Audio Adapter or FiiO BTR3K).
  • ๐Ÿ”ง If the problem is in the phone amplifier, contact the service center (replacement will cost you a lot of money). 1.5-3 thousand rubles).

๐Ÿ’ก

External DAC will not only amplify the sound, but also improve its quality by bypassing the built-in audio track of the smartphone, which is true for models without a separate audio chip (for example, the Redmi 10 or the POCO M4 Pro).

6.Alternative firmware: when MIUI is too restrictive

If you're willing to take drastic measures, installing custom firmware (like LineageOS or Pixel Experience) can solve the problem of sound limitations. MIUI, But there are risks:

Pros:

  • โœ… Full control over sound settings.
  • โœ… No forced "safe level" volume.
  • โœ… Possibility of installation ViPER4Android crutless.

Cons:

  • โŒ Loss of guarantee.
  • โŒ Risk of "bricking" of the device in case of installation error.
  • โŒ Possible bugs with camera or sensors (depending on the model).

Instructions for installing LineageOS for Xiaomi:

  1. Unlock the bootloader through the Mi Unlock Tool (requires an account binding Mi).
  2. Install TWRP Recovery for your model.
  3. Download the firmware from the official LineageOS website (select the version for your deviceโ€™s codename).
  4. Sweat through TWRP by first doing wipe of Dalvik, Cache, System, Data partitions.

โš ๏ธ Note: Some models (e.g. Xiaomi) 11T Pro) unlocking the bootloader results in Widevine blocking L1 โ€” This means that Netflix and other services will only work in the future. SD-quality.

7. Frequent mistakes and how to avoid them

When you try to turn up the volume, you often have a problem with the most common ones.

Problem.Reason.Decision
The sound became hoarse at maximum.Exceeded the power limit of the amplifierTurn down the volume by 10-15% or use an external DAC.
Settings are reset after rebootingThe Engineering Menu does not save the changesUse applications or edit system files
The amplifier application is not workingConflict with MIUI or lack of rightsTurn off the system equalizer in the sound settings
The sound disappears after the change mixer_paths.xmlIncorrect parameter valuesRestore the original file or check the syntax

Another common mistake is ignoring the impedance of headphones, such as 250 Ohms headphones (like the Beyerdynamic DT 770 Pro) that can't physically play loud on a smartphone without an amplifier.

  • ๐ŸŽง Up to 32 ohms โ€“ suitable for smartphones.
  • ๐ŸŽง 32-100 Om โ€“ require a high-quality amplifier.
  • ๐ŸŽง Up. 100 Ohm - need a full-fledged DAC/booster.

๐Ÿ’ก

To quickly check the impedance of the headphones, look at the box or sticker on the device itself. Usually the value is indicated next to the model (for example, "32ฮฉ").

Can I turn up the volume without root rights?
Yes, there are several ways: Use applications like Volume Booster or Equalizer FX. Set the equalizer to MIUI. Enable the "Accelerated Headphone" option in the settings. However, the maximum effect without root is limited to ~15-20% volume gain.
Why is the sound so quieter after the MIUI update?
Newer versions of MIUI (especially MIUI 14+) tighten volume restrictions due to European regulations (EN 50332-2) to bring back the previous level: rollback to the old firmware version (risky). Using ViPER4Android with root. Install custom firmware (e.g. Pixel Experience).
Is it safe to listen to music at maximum volume?
No, it's fraught: ๐Ÿฉบ Hearing loss (according to WHO, safe level - up to the level of hearing loss) 85 dB 8 hours). ๐Ÿ”Š Damage to headphone speakers (especially in budget models). ๐Ÿ“ฑ Overheating of the audio chip in the smartphone (relevant for Snapdragon) 7xx/8xx). We recommend using the rule 60/60: more 60% volume 60 minute.
How to increase the volume of the microphone in headphones?
To strengthen the microphone: In the engineering menu (##4636##) Find the Mic Volume section and increase the value to 200-220. Use the Microphone Volume Booster app (but expect noises).If the microphone is too quiet in calls, check the VoLTE settings in Settings โ†’ SIM-maps and mobile networks. โš ๏ธ Increasing the microphone volume often results in echoes and backgrounds in conversation.Test settings before important calls!
Why is the sound less in games than in music?
V MIUI There are separate volume settings for: ๐ŸŽต Music and Media (maximum level). ๐ŸŽฎ Games (limited to 80% of maximum). ๐Ÿ“ž To keep the volume level: Open the game and press the volume button. Press the gear next to the slider and select Turn off the safe level. Use Game Turbo in MIUI โ€” There are separate sound settings for games.
