How to improve the sound on Xiaomi: from settings to upgrade equipment

Sound on Xiaomi devices is one of the most talked-about topics among users, even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro.+ Sometimes disappointing with bass frequencies or loud speakers, both hardware limitations (small speakers, lack of stereo sound on budget models) and software default settings that are rarely optimized for individual preferences.

In this article, we’ll break down 12 proven ways to improve sound – from hidden features MIUI You will learn how to adjust the equalizer for the genres of music, activate Dolby Atmos (even if it is not on the menu), choose the right Bluetooth codecs for headphones and when it makes sense to buy external accessories. TV Mi Soundbar, where the algorithms improve sound work differently than on smartphones.

Important: not all methods are universal. F5 supportive LDAC, Redmi 12 doesn't. We're going to put some nuances in each section so you don't waste time on useless manipulation.

1. Activation of Dolby Atmos and other sound effects

Many users are unaware that their Xiaomi supports Dolby Atmos or similar technologies – simply because the feature is hidden or disabled by default. MIUI 12, the algorithm is integrated into the firmware of most mid- and premium-segment models (e.g., Xiaomi). 13T, Poco X5 Pro).

To turn on Dolby:

1. Go to Settings → Sound and vibration → Sound effects.
2. Select Dolby Atmos (or Mi Sound Enhancer on older versions).
3. Activate Music, Movie or Game mode depending on the content.
4. The intensity of the effect is the optimal value for music: 60-70%.

On budget models (e.g. Redmi) A2) Dolby may not be there. In this case, try an alternative:

• 🎵 Mi Sound Enhancer – a simplified version with presets for bass and vocals.
• 🔊 Google equalizer (set separately from Play Market).
• 🎧 Wavelet (application with support) LDAC aptX).

An important caveat: Dolby Atmos consumes additional CPU resources. On weak chipsets (like the Snapdragon 4 Gen 1), this can cause audio delay when playing video, and if you notice lags, turn off the effect or reduce the intensity.

2. Set up the built-in MIUI equalizer

V MIUI There's a hidden 5-band equalizer that allows you to dot the frequencies, but by default it's hidden behind a non-obvious menu:

For smartphones:

1. Open the standard Music (or Mi Music) app.
2. During playback, tap the icon ⚙️ Settings in the upper right corner.
3. Select the Equalizer → Customized.
4. Set up sliders: 60Hz: +3 dB for bass (but not higher, otherwise there will be wheezing). 230 Hz: +1 dB for the "body" of sound. 910 Hz: 0 dB (leave neutral). 3.6 kHz: +2 dB for vocal clarity. 14 kHz: +1 dB for air (do not overdo it, otherwise there will be a hissing).

For Xiaomi. TV path:

1. Hold the Menu on the remote. → Settings → Sound.
2. Select Sound Mode. → Customized.
3. Activate Dynamic Bass (if any) and adjust the equalizer.

Bass (+3 dB at 60 Hz)|Clear vocals (+2 dB at 3.6 kHz)|Neutral average frequencies (0 dB by 910 Hz)|Minimization of hissing (not higher) +1 dB at 14 kHz)-->

The critical mistake of most users: they amplify the bass above +4 dB, which leads to distortion and overload of speakers. on Xiaomi with a single speaker (e.g. Redmi) 10A) This can cause physical damage to the membrane.

3. Optimization of Bluetooth codecs for headphones

If you listen to music through Bluetooth headphones, the sound quality depends not only on the headphones themselves, but also on the codec used. By default, Xiaomi often chooses to choose between the two. SBC — The simplest and worst codec in quality. Here's how to switch to the best:

Instructions for Android 12+ (MIUI 13/14):

1. Activate Developer Mode: Go to Settings → About Phone and tap the MIUI version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the Bluetooth Codec and select: 🎧 aptX Adaptive (the best for Sony) WH-1000XM5, Bose QC45). 🎧 LDAC (Maximum quality but high battery consumption). 🎧 AAC (Optimal for AirPods).

Reconnect the headphones.

⚠️ Note: Xiaomi with MediaTek Helio G chipset (e.g. Redmi) 12C) codec LDAC It can be unstable, the sound will be interrupted, and then you can choose aptX or AAC.

If there is no codec selection option in the developer menu, try the Developer Options Shortcut app (available on the Play Market) which will reveal hidden Bluetooth settings.
