How to increase the bass on the Xiaomi phone: from standard settings to engineering menu

Music lovers and fans of powerful sound often face a problem: even at maximum volume, the bass on Xiaomi sounds weak or absent at all. The reasons lie in the factory limitations of the sound system, small speakers and the program limits of MIUI. But the good news is that low-frequency amplification is possible without buying external speakers or headphones with an amplifier.

In this article, we will discuss 7 proven methods for pumping bass on Xiaomi, Redmi and POCO smartphones, from basic equalizer settings to hidden engineering menu features. All methods are tested on current MIUI 14/15 firmware and work without losing warranty. Importantly, some methods require caution, so read the warnings carefully before changing system settings.

1. Set up the built-in MIUI equalizer

The easiest and safest way to do this is to use the standard equalizer in your audio settings, which is available on all Xiaomi models starting with the Redmi Note 7 and Mi 9. The interface may vary slightly depending on the version of MIUI, but the algorithm is the same.

To activate the bass boost:

1. Open the Music app (or any other place where sound is played).
2. Click on the icon. ⚙️ Settings in upper right corner.
3. Select the Equalizer → Customized.
4. Move the sliders for 60 Hz and 100 Hz frequencies to +3...+5 dB.
5. To smooth the sound, reduce the frequencies of 250 Hz and 500 Hz by -1...-2 dB.

⚠️ Attention: Excessive bass reinforcement (more) +6 dB can cause sound distortion at high volume on single-speaker models (Redmi) 9A, POCO M3) The effect will be minimal - it is better to use headphones for them.

Activation of the Mi Woofer mode

Starting with the Xiaomi Mi 10 and Redmi K30 Pro, the company has added Mi Woofer technology — hardware amplification of low frequencies through a vibration engine.The function works only when you connect headphones (wired or Bluetooth) and converts the vibration of the body into additional bass.

How to turn on:

• 🔊 Go to Settings. → Sound and vibration → Mi Woofer.
• 🎧 Connect the headphones (required!).
• 🔄 Activate the switch and adjust the vibration intensity.

📌 The Mi Woofer is only effective on linear vibratory motor (Z-axis) models on budget smartphones with a rotary motor (Redmi). 8A, POCO C31) The function is weak or absent at all.

💡

For better effect, place the phone on a hard surface (table, armrest) with a screen upwards, and the vibration will be transmitted through the body, reinforcing the bass.

3. Use of third-party equalizers

The standard MIUI equalizer is limited to 5-7 bands and maximum gain of +6 dB. Third-party applications offer more features: 10-band equalizers, preamps and custom presets.

🔹 Important: MIUI 14/15 Some equalizers may not work due to the limitations of the audio effects policy. ADB:

adb shell pm grant com.pittvandewitt.wavelet android.permission.WRITE_SECURE_SETTINGS

4.Configure via the engineering menu (MTK/Qualcomm)

The engineering menu allows you to change the parameters of the sound system at the hardware level, which is suitable for advanced users, since incorrect settings can lead to damage to the speakers.

📱 For Qualcomm processors (Snapdragon):

1. Open the Phone app and type ##36446337##.
2. Go to Hardware Testing → Audio → LoudSpeaker Mode.
3. Increase the Speaker Gain and Headphone Gain values by 2-4 points.

📱 For MediaTek processors (Helio/Dimensity):

1. Enter the code ##4636## → select Hardware Testing.
2. Press Audio → Normal Mode → Speaker.
3. Change the Max Vol (maximum volume) and Min Vol (minimum volume) settings.

⚠️ Note: Speaker Gain increase by more than 5 units on single-speaker models (Redmi) 9C, POCO M2) It can cause wheezing and overheating of the sound chip.

Increase Speaker Gain by no more than 3 units at a time|

Test the sound at 50% volume before saving |

Do not change the settings of Microphone Gain (may worsen the quality of calls)|

Reset your settings when wheezing appears|-->

5. Modification of the file mixer_paths.xml (advanced)

File. mixer_paths.xml It's an Android audio track configuration, and editing it allows you to remove software volume and bass restrictions, but requires root rights or a patched boot image (Magisk.

Step-by-step:

1. Install Root Explorer or any file manager with root access.
2. Cross the path. /vendor/etc/mixer_paths.xml (or /system/etc/ firmware).
3. Find the following lines: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" />
4. Increase the value to 90-95 (no more!).
5. Save the file and restart the phone.

🔧 Rootless alternative: Some custom firmware (e.g. PixelExperience or LineageOS) already contain modified firmware mixer_paths.xml They're louder, and you can set them up through TWRP, But it voids the guarantee.

💡

Editing mixer_paths.xml It gives you maximum bass amplification, but it requires you to back up the original file.

6. Hardware solutions: headphones and external amplifiers

If software methods don't work, hardware improvements are worth considering. Even budget headphones with 32 Ohm impedance and a frequency range of 20 Hz will sound better than built-in speakers.

🎧 Best Options for Xiaomi:

• 🔊 Xiaomi Hybrid Pro HD — Hybrid speakers with bass amplification up to 40 Hz.
• 🎵 SoundPEATS Air3 — Bluetooth headphones with support AAC and aptX for pure sound.
• 🔋 FiiO BTR3K — External Bluetooth amplifier with equalizer (connects to the phone by phone) USB-C).

💡 Advice: On models with 3.5 mm connector (Redmi Note 11, POCO X3 Pro) you can use a headphone amplifier (e.g. Xiaomi Headphone Amplifier 2). +3 dB at low frequencies and reduces noise.

7.Alternative firmware with improved sound

Custom firmware often optimizes the sound system better than standard MIUI, such as crDroid and Havoc-OS include:

• 🔊 ViPER4Android FX — Professional sound processor with support for surround and bass amplifier.
• 🎛️ JamesDSP – ViPER alternative with lower battery consumption.
• 📱 Dolby Atmos – Spatial sound (works on all models, including Redmi 9).

🔄 How to install:

1. Unlock the bootloader through the Mi Unlock Tool (requires a Mi Account binding).
2. Install TWRP Recovery for your model.
3. Flush the firmware and modules of ViPER4Android or JamesDSP through Magisk.

⚠️ Attention: On models with Dynamic RAM Expansion (Xiaomi 12, Redmi K50) Custom firmware may conflict with the virtual memory function. Before installing, disable it in Settings. → Additionally. → Memory.
