How to add sound in Xiaomi headphones: from basic settings to hidden MIUI chips

You've turned on your favorite track, but the sound in Xiaomi's headphones seems too quiet? This problem is familiar to many owners of the brand's devices - especially on models with MIUI 12-14, where the manufacturer artificially limits the maximum volume "for safety." Fortunately, there are several ways to increase the volume without buying new headphones or risking damage to hearing.

In this article, we’ll look at all the current methods, from standard MIUI settings to hidden engineering menus and third-party applications that run on Redmi AirDots, Mi True Wireless, Mi Headphones and other models. Importantly, some solutions require unlocking the bootloader or root rights, but most of the methods are available without deep technical knowledge.

1. Check basic sound settings in MIUI

Before you dig deeper, make sure that the problem is not the trivial settings. On Xiaomi devices, three menus are responsible for sound — all of which can affect the final volume.

Open the Settings → Sound and vibration and check:

• 🔊 Media volume – the slider should be at maximum (sometimes reset after connecting new headphones).
• 🎧 Type of connected devices — MIUI It automatically detects the headphones, but sometimes it's wrong. ANC It is defined as “normal” and the sound is quieter.
• 🔕 Do Not Disturb – Even in Alarms Only mode, some notifications may mute music.

Pay special attention to the item Sound Quality (some firmware called Sound Effects).

• 🎛️ Equalizer – choose Preset Bass or Rock to amplify low frequencies (they subjectively make the sound “louder").
• 🔊 Volume amplifier - the option appears only when connected headphones.
• 🎵 Mi Sound Enhancer is Xiaomi’s proprietary technology that dynamically adjusts volume (does not work on all models).

Important! If you change your settings and you start to get distorted (wheezing, jamming), go back to the factory settings of the equalizer, which is a sign that the headphones are not working.

2. bypassing MIUI restrictions through the engineering menu

The manufacturer artificially limits the maximum volume in headphones to ~80% It's designed to protect the hearing, but the limitation can be circumvented through the Engineering Mode. Xiaomi/Redmi/Poco Qualcomm-powered.

Instructions:

1. Open the Phone app and type the combination: ##36446337## (or #4636### on older versions of MIUI).
2. Select Hardware Testing → Audio → Headset Mode.
3. In the Max Vol field, change the value from 144 (or 128) to 160 (maximum).
4. Save the settings and restart the device.

Make sure the headphones are connected

Write down the initial values of the parameters

Battery charge > 50%

Don’t interrupt the change process.-->

Warning: Increasing volume above factory limits can lead to:

• 🔇 Loss of sound quality (distortion at high frequencies).
• 🔋 Increased battery consumption.
• 🚨 Risk of damage to headphone speakers (especially on cheap models).

3.Use of third-party applications to amplify sound

If standard MIUI settings don't work, Google Play apps will come to the rescue, and we tested 10 popular utilities and selected the 3 most effective ones:

For installation:

1. Download the app from Google Play (links above).
2. Launch and give access to the sound settings.
3. Turn on the Volume Amplifier option (or similar).
4. Adjust the slider to a comfortable level (do not recommend maxing out!).

💡

If the sound becomes intermittent after installing the amplifier, try turning off Bluetooth HD Audio in the headphone settings.This feature consumes a lot of resources and can conflict with third-party applications.

Attention! Volume Booster applications run on top of the system mixer.

• 📱 They may conflict with corporate functions. MIUI (For example, Mi Sound Enhancer).
• 🔋 The battery consumption will increase by 5-15% active-use.
• 🔊 The sound quality at maximum will deteriorate (wheezing will appear).

4.Setting up Bluetooth codecs for wireless headphones

If you use Xiaomi wireless headphones (like the Redmi Buds 4 Pro or Mi True Wireless 3), the problem of quiet sound may be in the Bluetooth codec. By default, MIUI chooses SBC, the most versatile, but not the highest quality codec.

How to change the codec:

1. Put the headphones on the phone.
2. Open Settings → Connected devices → Settings gear next to the headphones.
3. Choose Sound Quality → Codec.
4. Try the following options in order of priority: 🎧 LDAC (Highest quality, but can be found on weak phones). 🎧 aptX Adaptive (optimal balance of quality and stability). 🎧 AAC (Good for music, but worse for video).

After changing the codec, check the volume on the same track. The difference can be as high as 30-40%! If the sound starts to break, go back to the SBC or AAC.

💡

On devices with Snapdragon 865/870/888 (e.g. Xiaomi 11T Pro, Poco F3), the LDAC codec may not work stable due to driver issues.

Redmi AirDots 3 Pro and Mi True Wireless 2: These models support the same model. LC3 (The new Bluetooth 5.2 standard, but MIUI It often doesn't recognize it correctly, to get the phone to use. LC3:

1. Turn off the headphones.
2. Go to Settings → System → Settings Reset → Reset Bluetooth settings.
3. Reconnect the headphones and select the LC3 manually.

5. Hardware methods: cleaning connectors and replacing nets

Sometimes the problem with quiet sound is not the software, but the physical condition of the headphones, especially for wired Xiaomi models, where the Type-C or 3.5 mm connector becomes contaminated over time.

Checklist for diagnosis:

• 🔍 Check the headphone jack for dust/mud (use a flashlight).
• 🔊 Try the same headphones on another device – if the sound is the same quiet, the problem is with them.
• 🎧 Check the speaker grids – they can get clogged with earwax (relevant for Mi In-Ear).
• 🔌 If you use a Type-C adapter → 3.5mm, try without it.

How to clean your headphones:

1. For speaker nets: Use a toothpick with cotton wool dipped in alcohol. Don't push hard - the membrane is thin!

3.5mm connector

1. Turn off the phone.


2. Gently blow the connector with compressed air (a canister for cleaning equipment).




3. If there is oxidation, wipe the contacts with a stripe.

💡

For Xiaomi Mi ANC headphones with active noise cancellation, a quiet sound can be a sign of a dead battery.Put them on charge for 30 minutes - sometimes this solves the problem.

Attention, if you cleaned it down, or you had wheezing, you could have damaged the speaker's membrane.

• 🛠️ Contact Xiaomi Service Center (Warranty covers defects in speakers).
• 🔊 Try rolling back the sound settings to factory (Settings) → System system → Resetting settings → Resetting the sound settings).

6 Advanced methods: ViPER4Android and Magisk modules

For users with unlocked bootloader and root rights, powerful fine-tuning tools are available, the most popular being ViPER4Android, which allows:

• 🎛️ Increase the volume above system limits.
• 🎧 Set up an equalizer for a specific headphone model.
• 🔊 Apply the effects of the environment (concert hall, studio, etc.).

Installation instructions:

1. Install Magisk (if not already installed).
2. Download the ViPER4Android module (version for Android 10+).
3. Install the module via Magisk Manager and restart the device.
4. Open the ViPER4Android app and activate: Master Limiter (increases maximum volume). Convolver (for environmental effects). Equalizer (configure to your headphones).

For Xiaomi models with Qualcomm processors, the JamesDSP module is also available, which works similarly to ViPER4Android, but with support for LDAC and aptX.

Warning: Using ViPER4Android with default settings can:

• 🔇 Lead to clipping (distortion of sound at high volume).
• 🔋 Increase battery consumption by 20-30% due to constant sound processing.
• 🚨 Cause errors in system applications (e.g. com.android.media).

7. Alternative solutions: from custom firmware to replacement headphones

If none of these methods worked, consider radical options:

1. Installation of custom firmware

Some firmware (such as Pixel Experience or LineageOS) don't have a hard volume limit.

• 🔧 The loader is required to be unlocked and TWRP.
• 📱 Possible problems with Xiaomi branded features (for example, Mi Sound Enhancer).
• 🔊 The guarantee will be lost.

2. Purchase of External DAC (DAC)

For audiophiles, an external digital-to-analog converter (such as the Xiaomi USB-C DAC or iBasso DC05) bypasses the phone's built-in sound chip, ensuring:

• 🎧 Clear sound without distortion.
• 🔊 Ability to increase volume without loss of quality.
• 🎛️ Support for high-omnipotence headphones (300 ohms and above).

3. Headphone replacement

If your Xiaomi model has been in service for more than 2 years, the speakers could degrade.

• 🔊 The sound is quiet even at maximum.
• 🎧 There were wheezing at high frequencies.
• 🔋 The battery (in wireless models) holds a charge for less than an hour.
