How to increase the sound in headphones on Xiaomi smartphones: from standard settings to hidden functions

You've connected your headphones to the Xiaomi Redmi Note 12 or POCO X5 Pro, but the sound is too quiet despite the maximum volume level? The problem is familiar to many smartphone owners of this brand. It's not always a fault of the headphones or the jack - often the fault is the software limitations of MIUI, which artificially lower the volume to protect hearing.

In this article, we’ll look at 7 proven ways to increase headphone sound on Xiaomi, including standard settings, engineering menus, and customized apps. Importantly, some methods require root rights or may void warranty — we’ll mark them separately. Start with the safest options that work on all models from the Redmi 9A to the flagship Mi 14 Ultra.

1. Checking basic volume settings

Before digging deeper, make sure the problem isn't in the obvious. Xiaomi has separate volume controls for media, calls and alarms - they're easy to confuse.

How to check:

• 🔊 Press the physical volume button on the side of your smartphone. a slider will appear - make sure it is set to maximum and displays the headphone icon (not the dynamics).
• 🎧 Open any audio application (such as Mi Music or YouTube) and check the internal volume control inside the player – it can duplicate the system.
• 🔄 Reboot your smartphone with your headphones connected. MIUI Resets the sound settings after an update or crash.

If the sound is still quiet after this manipulation, move on to the next section. On models with Qualcomm Snapdragon (for example, POCO F5), it often helps to reset the sound settings through the engineering menu — more about this below.

2. the uniformity of sound (Equalizer)

MIUI has a built-in system equalizer that can inadvertently turn down the volume at certain frequencies, for example, if the Bass or Jazz preset is activated, the high frequencies are muted, making the overall sound seem quieter.

How to turn off or configure the equalizer:

1. Open Settings → Sound and vibration → Sound quality.
2. Choose the Equator and install the Preset Flat or No Preset Off.
3. If you want to experiment, try Rock or Pop presets, which usually amplify the average frequencies.
4. Activate the option Adaptive sound (if any) – it automatically adjusts the volume to the surrounding noise.

💡

On some models (like the Redmi K60), the equalizer is hidden, so to open it, plug your headphones in and launch any audio application, and then the sound quality item will become active.

If after resetting the equalizer, the volume increased, but still not enough, move to more radical methods.

3. Engineering menu: hidden volume settings

Xiaomi smartphones have a hidden engineering menu (Engineer Mode) where you can manually increase the maximum volume for headphones, a method that works on most models with Qualcomm and Mediatek processors, but requires caution - incorrect settings can damage the speakers.

Instructions for Qualcomm (Redmi Note 11, POCO X4 Pro, etc.):

1. Open the Phone app and enter the combination: ##36446337##Engineering Mode (MTK) menu will appear.
2. Go to Hardware Testing → Audio → Headset Mode.
3. In Max Vol, set the value to 150 or 160 (usually 128).
4. Save the settings and restart the smartphone.

For Mediatek (Redmi 10A, POCO C40, etc.):

• 📱 Enter the dialer: ##4636##
• 🔧 Choose Audio. → Volume and increase the Headset values by 20-30% from current.

⚠️ Warning: Changes to the engineering menu will not persist after resetting or updating MIUI. Some mobile operators also block access to these combinations.

4.Applicants for sound amplification

If standard methods didn't work, try third-party utilities that work on top of system settings and can increase volume by 20 to 50 percent. We tested 5 popular apps -- the results in the table below.

Recommendations for use:

• 🎵 For simple amplification of the sound, select Precise Volume – it does not require root and has minimal distortion.
• 🔊 ViPER4Android It gives you maximum volume gain, but it's complicated to set up. ViPER4Android Install Magisk and get root. 2. Download the latest version of ViPER from the official website. 3. Install drivers via Magisk Module. 4. In the application settings, activate Master Limiter and increase Pre-Amp to +3.0 dB.
• 🚫 Avoid apps like Super Volume Booster, which often contain malicious code.

⚠️ Attention: Apps to amplify sound increase the load on the audio chip. With prolonged use at maximum volume, the smartphone can overheat, and headphones can deteriorate.

5. Cleaning the connector and checking the headphones

If software methods fail, the problem may lie in the physical connection, and dust, contact oxidation, or a damaged headphone cable often causes a quiet sound.

How to check:

Connect your headphones to another device (PC, other smartphone)|Try other headphones in the same connector |Look at the 3.5mm connector for contamination |Check the headphone cable for bending and damage-->

To clean the connector:

1. Turn off your smartphone.
2. Take a wooden toothpick and carefully remove the dust from the connector.
3. Wet the cotton swab in alcohol and wipe the contacts inside the connector.
4. Let dry for 10-15 minutes before connecting the headphones.

If the sound is better after cleaning, but still quiet, the problem may be the audio chip on the smartphone, and that's where the service center will help.

6. Update firmware and reset settings

Sometimes the quiet sound in the headphones is a bug of a particular version of MIUI. For example, MIUI 14 for the Redmi Note 11 Pro had an issue with audio drivers that was solved by the update.

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version.
3. If the update didn’t help, try resetting the sound settings: Settings → System → Resetting → Reset network and sound settings

If the problem has occurred after the update, you can roll back to the previous version of MIUI via Fastboot.

⚠️ Warning: Resetting will delete all user data, including photos and apps. pre-backup through Settings → Additionally. → Backup and reset.

7. Alternative methods: Bluetooth and USB-C

If nothing has worked, consider alternative headphone connectivity options:

• 🎧 Bluetooth headphones: Modern models (for example, Xiaomi Buds 4 Pro) support codec LC3, which gives a cleaner and louder sound than wired headphones.
• 🔌 USB-C Adapter: If you use a 3.5mm connector, try connecting via an adapter USB-C → 3.5 mm on certain models (e.g, POCO F4) This gives you a 15-20 volume increase%.
• 🔊 External DAC: For audiophiles, an external digital-analog converter (for example, iBasso) is suitable. DC05). It bypasses the smartphone’s built-in audio chip, providing a more powerful signal.

If you still want to stay on wired headphones, try low-impedance (16-32 Ohm) models like the Xiaomi Hybrid Pro HD or the 1MORE Triple Driver – they are better compatible with Xiaomi audio chips.

💡

On smartphones without a 3.5mm connector (such as the Mi 11 Ultra), the sound via Bluetooth or USB-C adapter will be louder than through the adapter in the kit.
