How to increase the sound on Xiaomi 11T: from basic settings to hidden features

The weak sound on the Xiaomi 11T is a common problem, especially after MIUI updates or when using high-impedance headphones. Many users complain that even at maximum volume, the speakers sound quieter than competitors like the Samsung Galaxy S21 or iPhone 13.

In this article, we will look at all possible ways to increase volume, from standard settings to hidden functions of the engineering menu and third-party utilities. Importantly, some methods require caution, as they can damage speakers with prolonged use at high levels. We will also tell you how to check whether quiet sound is the result of a hardware malfunction (for example, a clogged speaker or a damaged plume).

If you hear distortions or wheezing as the volume goes up, it's a signal that the speakers are working at their limits, and then you'd better go to a service center than risk permanently disabling them.

1. Basic volume settings in MIUI

Before you resort to radical measures, check the standard sound settings. Xiaomi 11T has several regulators that are often overlooked:

Path to settings: Settings → Sound and vibration → Volume

Here you will see sliders for:

• 🔔 Media – volume of music, video, games;
• 📞 Calls – the signal level of the incoming call;
• 🔔 Notifications – the sounds of messages and alerts;
• 🔊 Alarm clock – a separate regulator for the alarm clock signal.

Note that MIUI 13/14 has an Adaptive Sound feature that automatically adjusts the volume to the noise level in the room, and if it's on, try turning it off, because sometimes the algorithm lowers the sound unnecessarily.

Activation of "Mi Display" mode to amplify sound

Mi Sound Enhancer is Xiaomi’s proprietary technology that improves the sound of speakers by optimizing frequencies. In Xiaomi 11T, it works especially well thanks to Harman Kardon’s stereo speakers.

How to turn on:

1. Open the Settings. → Sound and vibration.
2. Choose Sound Quality.
3. Activate the Mi Display switch.
4. In the section Sound Effects, select a profile: 🎵 Music - to listen to tracks; 🎮 Games to strengthen bass; 🎬 Movies to improve speech.

If the sound is louder after turning on, but there are distortions, try adjusting the equalizer manually, for example, reduce the low frequencies (bass) to avoid overloading the speakers.

💡

Me Display uses 5 to 10 percent more power, and if you notice a fast battery drain, turn it off after listening to music.

3. Engineering menu: hidden volume settings

Xiaomi 11T has a hidden engineering menu where you can manually increase the maximum volume level.Warning: incorrect settings can cause damage to the speakers!

Instructions for entry:

1. Open the Phone app.
2. Enter the combination: ##3644633## (or #4636## for the alternative menu).
3. Choose Hardware Testing → Audio.
4. In LoudSpeaker Mode, find the following options: Max Vol – maximum volume; Type – speaker type (select Loud Speaker); Value – current value (usually 144 or 160 by default).

Value

160

180

Set

Important: When you change the parameters in the engineering menu, check the sound at different frequencies. If you have wheezing, return the values to the factory.

4. Apps to amplify sound: top-5 utility

If the standard methods didn’t work, you can use third-party applications, we tested 15 programs and selected the 5 most effective for Xiaomi 11T:

Recommendation: Try Equalizer FX or Precise Volume first, they don’t require root rights and give a noticeable volume boost without risk to speakers.

Make sure the app is compatible with MIUI 13/14|

Start with minimum gain (+3-5 dB) and gradually increase |

Monitor the temperature of the phone (overheating speakers is dangerous)-->

5. Checking for hardware malfunctions

If the sound stays quiet even after all the settings, the problem could be a physical breakdown.

Signs of hardware malfunction:

• 🔊 The sound is distorted even at medium volume;
• 📵 One of the speakers (top or bottom) is not working;
• 💦 The sound becomes quieter after getting moisture;
• 🔧 Crunch or crack when changing volume.

How to check:

1. Connect headphones – if the sound is loud, the problem is with the phone’s speakers.
2. Call your phone from another device and turn on speakerphone, and if you hear you quietly, the microphone or the top speaker is faulty.
3. Light a flashlight into the speaker – if dust or debris is visible, clean it gently with a soft brush (do not use needles or toothpicks!).

⚠️ Warning: If the speaker doesn't recover after cleaning, don't try to disassemble the phone yourself. 11T speakers soldered to the motherboard, and their replacement requires soldering and special equipment.

6. Alternative methods: Bluetooth amplifiers and external speakers

If software methods do not give results, consider hardware solutions:

Sound amplification options:

• 🎧 Bluetooth amplifier (e.g. FiiO) BTR5) — connects to the phone and enhances the signal for headphones;
• 🔊 Portable Bluetooth speaker (e.g. Xiaomi Mi Portable Speaker) – the sound will be louder and better;
• 📱 FM-transmitter – transmits sound to a car tape recorder or stationary acoustics;
• 🎵 USB-C → 3.5mm adapter with amplifier (e.g. Apple) USB-C to 3.5 mm) – improves sound in wired headphones.

Advantages of external devices:

There is no risk of damaging the phone’s speakers.

- The sound quality is higher than that of the built-in speakers;

It can be used in different rooms (for example, a column on the street).

Disadvantages:

- Additional expenses (1,000 to 10,000) ₽);

- Need to carry another device.

💡

External amplifiers and speakers are the safest way to get a loud sound without risking the phone.

7. Resetting the sound settings to factory

If after experiments with sound there are problems (for example, the sound in the headphones is lost or the speakers work out of synchrony), reset the settings:

Instructions:

1. Go to Settings → System and device → Resetting.
2. Select Reset Network, Sound and Display settings.
3. Confirm the action (password or pattern lock may be required).
4. After the reboot, check the sound – it will return to factory parameters.

⚠️ Warning: This reset will also reset Wi-Fi, Bluetooth and screen brightness settings. save passwords from networks in advance!

If the reset didn’t help, try a full reset to factory settings (but pre-data backup).
