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

You turned on your favorite track at full volume, but the sound in Xiaomi headphones is still too quiet? This problem is familiar to many owners of Redmi, Poco and Mi-series smartphones. The reasons can lie in both the software limitations of MIUI and the hardware features of a particular model. In this article, we will discuss 7 working ways to increase the volume, from basic settings to hidden functions of the engineering menu.

It's important to understand that not all methods are equally safe. Some can cause sound distortion or even damage to speakers over long periods of time. We've identified the risks in each section so you can choose the best option. Let's start with the simplest solutions -- you may not even have to dig through system files!

1. Checking basic volume settings

Before you resort to radical measures, make sure that the problem is not the banal settings. MIUI has separate volume controls for multimedia, calls and alarms, often users confuse them or accidentally reset settings.

How to check:

• 🔊 Open the Quick Settings Panel (swipe down from the top edge of the screen) and make sure the volume slider is set to maximum.
• 🎵 Run any audio app (such as Mi Music or YouTube) and click on the speaker icon in the notification bar – there may be a separate headphone regulator.
• 🔧 Go to Settings. → Sound and vibration → Volume and check all sliders (especially Multimedia").

In 80% of cases, the quiet sound in Xiaomi headphones is due to the wrong volume settings in MIUI, not hardware problems. If the volume has not changed after these manipulations, move to the next section.

2. disabling volume limitation in EU-firmware

Many Xiaomi smartphones officially sold in Europe have a software limit to 85 dB, a requirement of local regulators to protect hearing, which applies even if you bought a phone in another region, but it is on EU-ROM.

How to remove the constraint:

1. Open the Settings app.
2. Go to Sound and Vibration → Additional settings.
3. Find the Safe Volume or Headphone Volume Limit and turn it off.
4. Confirm the action by taking a warning about possible harm to hearing.

Check the current version of MIUI in Settings → About the phone

Make a backup copy of important data

Charge your phone at least 50%

Turn off Bluetooth headphones (if you use them)

-->

⚠️ Warning: Once the limit is turned off, the volume can become uncomfortablely high, especially in cheap headphones. 70-80% level and gradually increase to avoid damaging hearing or dynamics.

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

If standard settings don’t work, you can turn to the engineering menu, the hidden Android section where advanced audio options are available.The method works on most Xiaomi models, but the menu interface may differ depending on the processor (MediaTek or Qualcomm).

Instructions for MediaTek (Redmi 9/10/Note 11, etc.):

1. Open the Phone app.
2. Enter the combination: ##36446337## (code may not work on newer versions of MIUI).
3. Go to the Hardware Testing → Audio section.
4. Select Headset Mode and increase the Max Vol values for left and right channels (standard values: 150-160, you can raise to 180-200).

For Qualcomm (Poco X3/X4, Mi 11, etc.):

1. Enter the phone app: ##4636###.
2. Select Audio → Headset.
3. Increase the Volume and Max Volume settings (do not exceed 200 units!).

⚠️ Warning: Changes to the engineering menu are not reset after restarting! If distortions appear after volume increase, return the values to the standard (usually 150-160) Or reset your settings through Settings. → System system → Resetting settings.

4.Applicants for sound amplification

If you don't want to go through the system settings, you can use third-party apps that work like software amplifiers, increasing volume through sound processing algorithms, and the downside is the possible deterioration of quality (noise, distortion).

Top.-3 tested applications:

• 🎧 Volume Booster GOODEV — A simple booster with presets for different types of headphones. Supports Xiaomi on Qualcomm and MediaTek chips.
• 🔊 Equalizer FX — Not only does it amplify the sound, it also allows you to tune the equalizer.
• 📱 Precision Audio – Advanced Tool with Support ViPER4Android (Requires root rights for full functionality).

How to set up Volume Booster GOODEV:

1. Install the app from Google Play.
2. Launch it and give access to the sound settings.
3. Activate the Boost Volume switch.
4. Move the slider 120-130% (above is the risk of distortion).
5. Turn on the Safe Mode option to avoid damaging the speakers.

💡

Before using the sound booster, check the headphones at maximum volume without the application. Even so, the sound is clean, you can safely increase the volume in the Volume Booster to 130-140%.

5. Equalizer setting in MIUI

The built-in equalizer in MIUI is often ignored, but it can significantly improve sound perception. The right settings will make music louder by adjusting frequencies, rather than simply increasing the amplitude, and this is especially true for headphones with poor sound insulation (for example, Xiaomi Basic or Redmi Buds).

How to set up:

1. Open any audio app (such as Mi Music).
2. During playback, tap on the icon. ⚙️ Settings → equalizer.
3. Choose Rock or Pop presets – they amplify the medium and high frequencies, which subjectively makes the sound louder.
4. Manually lift the sliders at 100-300 Hz (bass) and 3-6 kHz (medium frequencies) on 2-3 divisions.
5. Turn off the Auto option if it is active – it resets settings.

For models with Qualcomm Snapdragon (for example, Poco X3 Pro or Mi 11), an extended equalizer Mi Sound Enhancer is available:

• Go to Settings → Sound and vibration → Sound quality.
• Activate Mi Sound Enhancer and select Dynamic profile.
• Turn on the bass amplifier option and set the level to 50-70%.

💡

Tweaking the equalizer doesn't increase the physical volume, but by adjusting the frequencies, the music is perceived as more saturated and "louder," which is the safest way to improve the sound without risking headphones.

6.Cleaning the connector and checking the headphones

If all the software methods didn't work, the problem could be hardware, and most of the time, it's the fault of:

• 🧹 Contaminated connector 3.5 mm (dust, contact oxidation).
• 🔌 Damaged headphone cable (especially on cheap Xiaomi models).
• 🔋 Weak contact in wireless headphones (e.g. Redmi AirDots).

How to clean the connector:

1. Turn off the phone.
2. Take a wooden toothpick and carefully remove visible dirt from the connector.
3. Wet the cotton swab in isopropyl alcohol (at least 70%) and wipe the contacts.
4. Allow the connector to dry for 10-15 minutes before use.

To check the headphones:

• Connect them to another device (laptop, other smartphone).
• Try other headphones in your Xiaomi.
• If the sound is quiet everywhere, the problem is with the headphones, unless on Xiaomi it is on the phone.

⚠️ Warning: If the headphones are no longer recognizable after cleaning, check if the contacts inside are bent, in which case you will need to replace the connector in the service center (cost for Xiaomi is from 800 to 1500 rubles).

7. Alternative solutions for wireless headphones

If you have Redmi AirDots, Xiaomi Buds or other wireless headphones, the quiet sound problem may be related to:

• 📶 Weak Bluetooth signal (especially at a distance of more than 5 meters).
• 🔋 Low headphone charge (at a level below 20%, the volume automatically decreases).
• 🎛️ Bluetooth codecs (for example, SBC sounds quieter than AAC or).

How to improve sound:

1. Go to Settings → Connected Devices → Bluetooth Settings.
2. Find your headphones in the list and tap on ⚙️ near.
3. Choose Sound Quality → High (if available).
4. Turn off the option Absolute Volume (it synchronizes the volume level between the phone and headphones, which sometimes leads to restrictions).

For models with LDAC support (e.g. Xiaomi Buds 3 Pro):

• Install the Developer Options app (if not, activate the Developer Mode via Settings → About Phone → MIUI version – tap 7 times).
• In Settings → System → Advanced settings → Developer options find the Bluetooth Codec.
• Select LDAC and set the bitrate to 660 kbps (maximum quality).
