How to improve the sound quality on Xiaomi phone: from basic settings to advanced hacks

The sound on Xiaomi smartphones is often a stumbling block even for flagship models. Users complain of quiet speakers, distorted low frequencies in headphones or insufficient volume during calls. MIUI, It's also the hardware of a particular model, from the Redmi Note 12 to the Xiaomi 14 Ultra, but the good news is that 90 percent of the time, the sound quality can be significantly improved without buying a new device.

In this article, we will analyze 10 proven methods – from hidden settings MIUI You will learn how to adjust the equalizer to specific genres of music, which codes of the engineering menu are responsible for sound, and why it is sometimes enough to simply clean the headphone jack, POCO F5 Xiaomi 13T), where the potential for sound improvement is particularly high.

Important: All recommendations tested on current versions MIUI 14/15 If your phone runs on older firmware, some menu items may be different — we will warn you about this separately.

1. Basic sound settings in MIUI: what you missed

So let's start with the obvious -- the standard audio settings that many users ignore. MIUI There are hidden options that you can't see on the first screen, like the default Dolby Atmos mode is disabled on most models, although it can add volume to the sound.

How to open the advanced settings:

• 🔊 Go to Settings. → Sound and vibration
• 🎵 Slip on sound quality (some models call this item the effects of sound)
• 🔧 Enable Dolby Atmos and select Music or Movie profile (for movies)
• 📱 For models with stereo speakers (for example, Xiaomi 12 Pro) activate the Stereosound option

Pay attention to the slider Volume Multimedia - in MIUI It's often limited to 70 percent of the maximum. To break that limit, you'll need an engineering menu (more on that in the next section). Also check if Do Not Disturb or Quiet mode is activated -- they can silence the sound even at maximum volume.

⚠️ Attention: On models POCO M5 redmi A2 Dolby Atmos may not be available due to hardware limitations, in which case use third-party equalizers (Section 3).

2. Engineering menu: how to remove volume restrictions

Manufacturers often artificially lower the maximum volume to protect speakers from overload. At Xiaomi, this is done through hidden settings that can be changed using an engineering menu. The method works on 80% of models, but requires caution - incorrect settings can lead to distortion of the sound.

Instructions for entering the engineering menu:

1. Open the Phone app and type the combination: ##36446337## (some models run ##4636###)
2. Choose Hardware Testing → Audio
3. In the LoudSpeaker Mode section, find the settings: Max Vol – maximum volume (the default value is usually the default value). 140-160) Min Vol - Minimum Volume Current Vol - Current Volume

Max Vol

For models with HyperOS (e.g. Xiaomi 14), the path may be different: Hardware Testing → Speaker → Volume Settings.

⚠️ Warning: After changing the values in the engineering menu, be sure to restart the phone. Otherwise, the settings may reset after the first call or playback of music.

3. Third-party equalisers: top-3 apps

Built-in equalizer in MIUI frequently 5-7 In the same way, third-party applications offer 10-15 adjustment bands, presets for different genres and even 3D-We tested the effects. 12 The best two equalizers and chose the best three for Xiaomi.

Top.-3 applications:

• 🎧 Wavelet (free, with purchases inside) 9-band equalizer with presets for Xiaomi Automatic sound correction under headphones Support LDAC aptX
• 🎛️ Poweramp Equalizer (paid, 349)₽) 10-band equalizer with limiter Works with any players Minimum sound delay
• 🔊 ViPER4Android (Free, requires Magisk) 15-band equalizer with Surround and Bass Boost effects Dolby Digital and DTS Requires root rights for full functionality

To install ViPER4Android on Xiaomi without root rights:

1. Download. APK from the official website viperatmos.com
2. Install the application and open it.
3. Enable the Compatibility Mode option in the settings
4. Select the Legacy Mode driver (for the MIUI 12-14)

Wavelet is best suited for HyperOS models, as it works correctly with the new audio driver. POCO and Redmi with MIUI 13 - it's more stable than the rest on this firmware.

💡

If after installing the equalizer the sound became intermittent, disable the option "Audio Effects" in the settings MIUI (Settings → Sound. → Sound quality).

Hardware modifications: when software methods are insufficient

If you've run out of software, but the sound still doesn't work, you should consider hardware modifications. This is true for monodynamic models like Redmi. 10C) Or a weak, enhanced headphone output:

Methods of hardware upgrade:

• 🔧 Replacement speaker: Xiaomi is suitable speakers from Meizu or Realme with similar resistance: 300-800₽ for the original speaker, 1500-2500₽ for a premium option (for example, with a neodymium magnet)
• 🎧 Modification of the connector 3.5 mm: Installation of the amplifier ES9018K2M for clean sound in headphones Requires rations and knowledge of circuitry
• 🔊 Adding a second speaker: Possibly on models with a metal body (e.g, POCO X3 Pro) Need a resistance speaker 8 Ohm and power. 0.5-1 Watt

To replace the speaker on Xiaomi will need:

• Plastic blade for opening the body
• A soldering iron with a thin sting (for weeding off an old speaker)
• Multimeter to check resistance of new speaker
• Clay. B-7000 fixative

The process of replacing the speaker with the Redmi Note 11 (Step-by-step):

⚠️ Attention: On models with IP53 (For example, Xiaomi 13) after opening the case, the water protection is lost. ~500₽).

5. Optimizing sound for specific scenarios

Sound quality depends not only on the settings of the phone, but also on how you use it. For example, when watching a YouTube video, sound may differ from playing through Spotify because of different codecs.

Music through headphones:

• 🎵 Use Poweramp or Neutron Player – They Bypass the Limits MIUI bitrate
• 🔊 Turn on Hi-Res Audio in the player settings (requires headphones with support) LDAC)
• 🎛️ In the equaliser, raise the frequencies. 60-80 Hz (for bass) and 10-12 kHz (for tops)

Calls and voice messages:

• 📞 Enable Voice Improvement in Settings → Special opportunities → Rumor
• 🔇 Turn off noise reduction in microphone settings – it often cuts high frequencies
• 🎤 Use an external microphone (e.g. Lavalier) to record. BOYA BY-M1)

Games:

• 🎮 Enable Game Mode in Settings → Special. capabilities - it optimizes the delay of sound
• 🔊 Use low latency headphones (aptX) LL)
• 🎛️ In the equalizer, increase the frequencies. 200-500 Hz for better hearing steps in shooters

For models with infrared port (e.g, POCO M4 Pro) you can output the sound to the external acoustics through an IR transmitter:

1. Download the Mi Remote app
2. Add a device like the Amplifier or Soundbar
3. In the sound settings, select the External speaker (IR)

💡

For streaming music via Bluetooth, always use a codec. LDAC (990 kbit/s) instead of the standard SBC (The difference in quality is noticeable even on budget headphones.

6.Diagnostics of sound problems: when to contact the service

If the sound is still bad after all the manipulations, the problem may be hardware, and here are some signs you should contact the service center:

Symptoms of malfunction:

• 🔊 Wheezing in dynamics at any volume - a sign of a damaged membrane
• 🎵 No sound in one headphone – a problem with the connector or audio chip
• 📱 The sound disappears when the phone is tilted - the plume of the speaker departs
• 🔋 Sound is distorted when the battery is low – a malfunction of the power controller

Before visiting the service, perform a diagnosis:

1. Test the sound through headphones – if the problem persists, the audio chip is to blame
2. Check the sound in safe mode (press the power button). → Safe regime)
3. Install the Phone Doctor Plus app and run the speaker test

Cost of repair in official Xiaomi services (2026):

⚠️ Warning: If the phone is warranty, do not open it yourself - this will void the warranty. In official Xiaomi services, audio diagnostics is free, even if you refuse to repair it.

7. Hidden chips MIUI for sound you didn't know about

MIUI It contains a few hidden features that can improve sound, but are not documented in the official instructions. MIUI 13+ hyperos.

Secret settings:

• 🔊 Monet Sound (only for Xiaomi) 13/14): Activated through ADB-Adb shell settings put global monet_audio_enabled 1 Adds spatial sound to stereo speakers
• 🎵 Super Volume (for all models): Included in the engineering menu (##36446337## → Audio → Super Volume: Increases volume by 15-20% distortionless
• 🎧 LDAC Priority (for Bluetooth): activated by command: adb shell settings put global bluetooth_aac_bitrate 3 Forcedly uses codec LDAC 990 qbit/s instead SBC

For models with HyperOS, the Dynamic Range Compression option is available, which automatically equalizes the volume between tracks.

1. Go to Settings. → Sound. → Sound quality
2. Tap 5 times on the Dolby Atmos item
3. In the menu that appears, turn on Dynamic Range

Nana POCO F4 GT Black Shark 5 has an additional game audio mode that reduces the latency to 80 ms (versus the standard 120 ms.

8. frequent user errors that spoil the sound

Many of the problems with sound on Xiaomi arise from the wrong actions of users.-5 Mistakes that make the sound worse:

Typical mistakes:

• 🚫 Use of non-original charging – cheap charging creates interference in the audio track
• 🚫 Cleaning the connector 3.5 mm with alcohol - it dissolves the contacts, it is better to use compressed air
• 🚫 Installing “sound amplifiers” from the Play Market – 90% of these apps are fraudulent
• 🚫 Ignoring firmware updates in new versions MIUI often correct audio bugs
• 🚫 Storing your phone next to magnets – this can demagnetize the speaker

It is especially dangerous to use "magic" applications to increase volume, which require root rights. mixer_paths.xml, If you've already installed an app like this, you can only return the original settings through flashing.

Another common mistake is to use headphones with impedance above 32 ohms without an amplifier. Xiaomi (except flagships) has a weak output cascade, so Beyerdynamic headphones DT The 770 Pro (80 Ohms) will sound quiet.The solution is external. USB-C amplifier (e.g. iFi Audio) GO bl).

💡

Never increase the volume in the engineering menu above. 200 units, which causes irreversible damage to the speaker coil: 160-180 most models.
