How to Improve Sound on Xiaomi Phone: A Complete Guide

Xiaomi’s modern smartphones are famous for their impressive performance, but audio capabilities are often underrated by users. Many device owners do not even realize that the built-in speaker or headphone access can produce much better and louder sound when properly configured. Standard factory settings are often conservative to prevent possible distortions, but they can be easily adapted to personal preferences.

If you notice that the music sounds flat and the video files barely distinguishable dialogue, do not rush to blame the hardware. MIUI operating system and its modern shell HyperOS hides a powerful toolkit for fine-tuning the audio stream, and the competent use of these tools allows you to turn a regular smartphone into a portable media center with rich sound.

In this article, we will look at all the available ways to improve the acoustic performance of your device, we will look at both built-in features and third-party solutions that will help you to get the most out of your existing equipment.

Basic setting of the system equalizer

The first step to quality sound is to work with a built-in equalizer. In Xiaomi smartphones, it is integrated directly into the system settings of the sound, which ensures stable operation without the need to install additional software. To access it, you need to go to the Settings menu → Sound and vibration → Sound effects.

You'll find preset profiles like Pop, Rock, Jazz or Classic, but blindly following these patterns doesn't always get the best result. Manually adjusting the frequency sliders allows you to tailor the sound to a particular song or genre you're listening to right now. Experiment with high frequencies to add air and low frequencies to enhance bass.

Note the Mi Sound Enhancer switch, which is designed to improve the detail of the sound, especially when using wired headphones, and activating this feature can significantly change the frequency response to make the sound more vivid and detailed, but on some models it can add digital distortion at maximum volume.

⚠️ Attention: When manually adjusting the equalizer, avoid over-raising the sliders to the top position. This can lead to wheezing and clipping, which not only worsens perception, but can theoretically damage the speaker when working at the limit for long periods of time.

For the best results, try this algorithm: reset the equalizer settings to zero, turn on your favorite track, and start smoothly raising frequencies while listening to changes, which allows you to find the middle ground for your hearing and the acoustics you use.

Use of Dolby Atmos and DTS technologies

Xiaomi and Redmi’s flagship and many mid-range models feature licensed surround sound technology, most commonly Dolby Atmos, which creates a three-dimensional sound space effect, a feature that is particularly useful when watching movies and TV shows, as it clearly separates voices and background noise.

Unlike a simple equalizer, Dolby Atmos processes sound in real time, analyzing content and distributing frequencies to create an environmental effect. In the sound effects settings, you can choose the profile "Auto", "Video", "Music" or "Voice". For everyday use, the "Auto" mode is the most optimal, since the system itself determines the type of content.

• 🎧 Video Mode – expands stereo and enhances dialogue, making watching movies more immersive.
• 🎵 Music Mode – Optimizes dynamic range, keeping details in quiet and loud sections of the track.
• 🗣️ Voice mode – maximizes the average frequencies, which is ideal for listening to podcasts and audiobooks.

It's worth noting that activating Dolby Atmos can consume additional CPU resources, which in rare cases affects battery life. However, on modern Snapdragon and MediaTek chipsets, this effect is almost imperceptible. If you use the phone as the main music box, this feature is mandatory.

Setting up Bluetooth codecs for wireless headphones

Wireless speakers often face a situation where the sound through Bluetooth seems to be less quality than through a wire. The problem lies in compression codecs. By default, the system can choose a low-bitrate codec to save energy, but the user can force this setting to change through the developer menu.

To activate hidden settings, you need to click seven times on the build number in the About Phone section to appear in the Developer Menu. Inside this section, look for Bluetooth Audio Codec. Here you will see a list of the formats supported by your smartphone and headphones: SBC, AAC, aptX, aptX HD, LDAC.

The choice of codec directly affects the quality of data transmission:

• 📉 SBC — basic codec, provides compatibility, but compresses sound quite strongly, cutting high frequencies.
• 📈 LDAC aptX HD — High-resolution codecs that transmit three times more data than standard Bluetooth, delivering sound close to Hi-Res.
• ⚡ aptX Low Latency is a specialized codec for games that minimizes sound latency, which is critical for synchronizing shots and steps.

Keep in mind that for advanced codecs (LDAC, aptX) to work, your headphones must also support them. If you choose LDAC and the headset only supports SBC, the connection will either not install, or the system will be forced to roll back to the basic protocol.

Also on the developer menu, you can find the option "Relative volume Bluetooth." If you have problems with dissynchronizing the volume of your phone and headphones (when the phone is 100% and the ears are quiet), try switching this switch.

Third-party applications for sound amplification

When built-in tools are scarce, Google Play apps come to the rescue, bypassing system volume limits and adding extra equalizer bands, and one of the most popular and effective solutions is the Volume Booster GOODEV app.

This application works like a software amplifier, raising the signal level above the standard 100%. The interface is extremely simple: one slider for general volume and several presets. However, using such programs requires caution, since they can put a load on the dynamic head.

Another powerful tool is Precise Volume, which allows you to create detailed volume profiles for different scenarios: separately for the headphones, separately for the speaker, separately for each application, you can set it to 80% sound on YouTube and 100% on the navigator.

⚠️ Note: Do not install amplification in third-party boosters above 20-30%. Exceeding this threshold leads to irreversible distortion of the sound wave (clipping), which sounds like a crack and can physically tear the speaker membrane in a short time.

Removing hardware problems and cleaning

Often, the silent sound is not caused by the simple physics, the speaker grids on Xiaomi smartphones get clogged with dust, earwax and pocket pile over time, creating a mechanical barrier to the sound wave, drowning out high frequencies and general volume.

Use a soft toothbrush or a special sticky strip to clean your equipment, strictly forbidden to use sharp objects (needles, pins) or blow with your mouth (humid air condenses inside), neat sweeping movements will help remove the bulk of the contaminants.

There is also a software method of "pushing" water or dust with a sound of a certain frequency. On the Internet you can find special tracks with a low-frequency humming (about 165 Hz), which cause the speaker membrane to vibrate with a large amplitude, blowing the excess out.

If the sound is better after cleaning, but the metal sound is coming, maybe the membrane has been damaged earlier or the contamination has gotten deeper, and then only disassembly and professional cleaning in the service will help.

Influence of covers and accessories

Don't discount the impact of accessories on sound quality. Many protective cases, especially those that aren't original or specific to a particular model, can cover speaker outputs. This often happens with thick silicone or leather cases.

Check if the cutouts in the case match the location of the speaker and multimedia on your Xiaomi. Even partial overlap can reduce the volume by 30-40% and change the timbre, making the sound deaf. Take off the case and compare the sound - the difference may surprise you.

Also, pay attention to the location of the smartphone during playback, if the main speaker is on the bottom (which is typical for most models), then holding the phone horizontally in landscape mode can block the sound with the palm, in such situations, using a stand or changing the grip helps.

💡

When watching video in horizontal mode, try not to close the lower face of the smartphone, where the main speaker is located, this will create a barrel effect and drown out the sound.
