Quiet sound on Xiaomi is one of the most common problems faced by smartphone owners of the brand. Even on flagship models like Xiaomi 14 Ultra or Redmi Note 13 Pro+, users complain about low volume speakers or headphones. The reasons can be different from the software limitations of MIUI to the physical wear of speakers, but in 90% of cases, the situation can be corrected without going to the service center.
In this article, weβll look at all the possible ways to increase volume, from basic audio settings to working with engineering menus and third-party utilities, and focus on hidden MIUI features that arenβt mentioned in the official documentation, but can increase volume by 20-30%, and learn how to avoid distortion at maximum volume and what to do if the Suddenly speaker is quieter after updating the firmware.
Important: the methods are suitable for all current models Xiaomi, Redmi and POCO based on MIUI 12-14 and HyperOS. If your smartphone is older than 2018, some items may be missing - check the availability of options in the menu.
Basic sound settings in MIUI: what can be changed without root
Before digging through the engineering menu or installing third-party apps, check the standard settings. MIUI has a few hidden settings that affect volume, but they are often overlooked.
Open Settings β Sound and vibration. The following options are available here:
- π Media volume regulates sound in games, videos and music, see if the slider is at a minimum.
- π Call volume - separately configured for calls and notifications, sometimes reset after updates.
- π§ Headphone volume β appears only when wired or Bluetooth headphones are connected.
- π Don't disturb -- if it's on, it can drown out all sounds. Check schedules and exceptions.
Note the optional settings (some firmwares call it More) that hide:
- ποΈ Equalizer β allows you to increase low or high frequencies, which subjectively increases the volume (especially noticeable in headphones).
- π Adaptive sound β automatically adjusts the volume to the surrounding noise. Sometimes it doesn't work properly, it's better to turn it off.
- π± Sound separation β if Bluetooth headphones are connected, check if the sound is duplicated on the phone speaker (this lowers the overall volume).
β οΈ Note: If after the update MIUI You've lost your menu items, reset your audio settings to the factory. β Annexes β Application management β Three dots (menu) β Reset your app settings. It won't delete your data, but it will return all audio settings to default.
2. Engineering menu: how to unlock hidden volume settings
Xiaomi smartphones have a hidden engineering menu where you can manually adjust the settings of speakers, microphones and even volume limits. This method does not require root rights, but requires caution β incorrect settings can lead to distortion of the sound.
To open the engineering menu:
- Open the Phone app.
- Enter the combination: ##36446337## (or #4636## on older models).
- Select the Hardware Testing option β Audio.
In the Audio menu, you are interested in the following sections:
| Section | What can be customized | Recommended values |
|---|---|---|
| LoudSpeaker Mode | Loudness of the main dynamics | Set Level 5 or Level 6 (maximum Level 7, but there may be distortions) |
| Headset Mode | Loudness in wired headphones | Level 4-5 (above - risk of damage to headphones) |
| Earphone Mode | Loudness in conversation | Level 3-4 (above β the interlocutor will hear the echo) |
| Mic Volume | Microphone sensitivity | Level 2-3 (above β will catch background noise) |
After you change the settings, press Set and restart your smartphone. If the sound gets worse (wheezing, crackling), return the settings to Level 0 or Default.
β οΈ Note: On some models (Redmi) 9A, POCO M3) The engineering menu may be missing or blocked, in which case try the alternative code: ##6484## or ##64663##.
Record the current parameters |Do not increase the volume above Level 6|Check the sound after each change |Reboot the phone after settings-->
3. Apps to increase volume: top-5 utility
If standard methods didn't work, you can use third-party applications, and they work in different ways: some just amplify the sound programmatically, others change the system settings (require root), and we selected 5 proven utilities that are virus-free and compatible with MIUI.
List of the best apps:
- π΅ Volume Booster GOODEV β louden 20-40% There are separate regulators for speakers, headphones and Bluetooth.
- π Precise Volume β allows you to fine-tune the volume in 1% increments, not the standard 15%. Useful for fine-tuning. Plus: runs on HyperOS.

How to install and configure:
- Download APK from the official website or APKMirror (donβt use unknown sources!).
- Before installation, enable Installation from unknown sources in Settings β Appendices β Special Rights.
- Launch the app and follow the instructions. ViPER4Android will require additional configuration through Magisk.
β οΈ Note: Apps like Volume Booster can increase volume by distorting sound. Prolonged listening to music at maximum volume through such utilities leads to accelerated wear of speakers (especially on single-speaker models like Redmi). 10A).

4. Bluetooth headphone problems: why the sound is quiet and how to fix it
If the volume drops only when you connect Bluetooth headphones, the problem may be codecs, MIUI restrictions, or the headphones themselves.
First, check:
- π Headphone charge β at a low charge level, many models automatically reduce the volume.
- πΆ Distance to smartphone β if you move further than 5 meters, communication weakens and the sound becomes quieter.
- π Bluetooth codec - in MIUI default is often used SBC, It's a volume limiter. Try switching to the volume limit. AAC or.

- Reset the sound settings: Settings β Applications β Application management β Three dots β Reset the application settings.
- If the problem has occurred after upgrading from MIUI 12 to MIUI 14, try rolling back via Fastboot (instruction below).
How to Reverse the Previous MIUI Version:
1. Download stable firmware for your model from https://new.c.mi.com/global/miuidownload/index
2. Rename the file to update.zip and place it in the root of the phone's memory.
3. Go to Settings β About Phone β System Update β Three Dots β Select a firmware file.
