Set up headphones in the phone Xiaomi Redmi: from wired to TWS

Modern Redmi and Poco smartphones have powerful audio processors that are often hidden behind standard Android settings. Many device owners are unaware that their headsets are capable of producing studio-quality sound if the software is properly configured. The basic configuration often limits dynamic range for the sake of saving charge or protecting hearing, which prevents the potential of acoustics from being unleashed.

Optimizing your MIUI or new HyperOS soundshell requires careful attention to hidden menus and engineering options. You don't need root rights, but knowing where the system utilities are will make it much easier. In this article, we'll look at how to turn mediocre sound into a rich and detailed audio experience.

Whether you use 3.5mm wired headphones or modern headphones TWS-With Bluetooth 5.0, the setup principles are similar, but there are nuances that are specific to the Xiaomi ecosystem, and understanding these features will avoid common errors when connecting external audio equipment.

Basic configuration of wired headsets

The setup should start with checking the physical connection and basic system parameters. Unlike many competitors, Xiaomi retains a separate menu for the wired peripheral, which is activated automatically when a jack is detected. However, automation does not always correctly determine the impedance of the connected device, which can cause the sound to be too quiet or distorted.

The first step is to go to Settings → Sound and Vibration, and there's a media volume slider that you can spin to the maximum and adjust with buttons on the case or the headset itself, so you can avoid digitally understating the signal level. If you're using a 3.5 mm USB Type-C adapter, make sure it supports analog signal transmission, because some budget cables only work with digital output.

The Mi Sound Enhancer is a software-based audio processing algorithm that tries to adapt the frequency response to the type of headphones connected. The system suggests choosing a profile: "Hearbursts," "Heardrops," or "Hearburst Headphones." Choosing the wrong profile can lead to loss of bass or unpleasant high frequencies.

💡

Use the original Xiaomi adapter or certified DAC-enabled cables to avoid cracking and playback interference.

Once you've chosen the type of device, the system will suggest calibration, and you'll be asked to listen to a few test signals and determine which one sounds cleaner, and you shouldn't rush to choose; if in doubt, you should skip this step and adjust the equalizer manually. Automatic calibration often gets it wrong in noisy environments.

Working with equalizer and audio effects

The built-in graphics equalizer is a powerful tool in the hands of Redmi users. Standard presets like Pop, Rock or Jazz are often over-enhanced and make the sound unnatural. To get a quality result, it is recommended to use manual frequency band tuning. The standard interface offers 5 or 10 bands, which is enough for a basic correction.

When manually tuning, it is important to understand the physics of sound. Low frequencies (30 to 250 Hz) are responsible for the bass and body of the track. Average frequencies (from 250 Hz to 4 kHz) carry basic information about vocals and most instruments. High frequencies (above 4 kHz) add air, detail and "sincereness" to the sound. Excessive lifting of any of the bands can lead to clipping - digital distortions when the signal exceeds the permissible level.

Newer versions of the HyperOS shell include an advanced audio manager that allows you to customize the sound separately for each application, which means you can create a high-frequency profile for podcasts to hear speech better, and a profile with powerful bass for games.

• 🎧 Low Frequency: Responsible for bass depth, gently raise for electronic music.
• 🎻 Mid Range: Critical for vocals, don't push higher +3 dB to avoid the “box” effect.
• 🎺 High Frequency: Adds brightness, but excess will cause whistling and fatigue of the ears.
• 🔊 Balance: Check the balance of left and right channels, especially if you use old headphones.

Setting up Bluetooth headsets and codecs

Wireless connectivity makes its own adjustments to sound quality. The main limiter here is the data codec used. Xiaomi smartphones support a wide range of codecs, from basic SBC to advanced aptX, aptX HD and LDAC. By default, the system often chooses a compatible, but not the highest quality codec to ensure the stability of the connection.

To activate the best codecs, you need to go to the developer menu. → The phone. → Press 7 times on "Version" MIUI». After the notification “You became a developer” appears, go back to the main settings menu, select Additional → For developers, in the list, find the Bluetooth audio codec section.

Choosing an LDAC or aptX HD codec gives you an increase in quality, but can increase battery consumption and reduce connection stability in places with a lot of radio interference. If the sound starts to interrupt, the system will automatically lower bitrate or switch to a simpler codec. Low latency is critical for games, so it is better to use aptX Low Latency or game mode in Bluetooth settings.

Also on the developer menu, you should pay attention to the "Absolute Volume" option, which synchronizes the volume slider of the phone and headphones. If you have problems with quiet sound even at maximum, try to switch this option. Sometimes, dissynchronizing the volume levels leads to the phone thinking that it is 100% twisted and the headphones 50%.

Game settings and reducing delay

For gamers, latency is a critical parameter. In competitive shooters or rhythm games, a fraction of a second can be worth winning. In games-sharp Redmi phones (K or Black Shark series), there is a separate Game Turbo mode that optimizes the audio subsystem.

Activation of the game mode occurs automatically when you start an application from the list of games, or manually through the sidebar. Inside the Game Turbo settings, you need to find the section "Enhance Sound" and activate the "Accelerate High Frequency" mode for steps or "Accelerate Low" for explosions. This is a software simulation, but it really helps to highlight important sound cues from the overall mix.

⚠️ Attention: Using maximum sound amplifiers in game mode can lead to rapid battery discharge and heating of the bottom of the smartphone, where the speaker and audio chip are located.

If you use a wired headset for gaming, make sure that the audio settings turn off any Virtual Surround effects, as they add an additional delay to the signal processing.

Resolving problems with quiet sound

One of the most common complaints users have is the low volume, especially when compared to other devices, often due to regional restrictions rather than hardware, and the EU firmware versions have strict hearing protection regulations that artificially lower the maximum output level.

There is a safe way to get around this restriction through the engineering menu, but it requires caution. In the Phone app, dial ##6484## to log in. CIT-You can check the speaker performance here, but for deep audio tuning, it’s better to use third-party but proven applications from Google Play that change the system volume values, such as Volume Control Plus.

It's also worth checking if Headphone Safety is enabled in your audio settings, which can dynamically lower the volume if you listen to music too long or too loud, and turning it off will give you full control of the signal level, but be aware of the risks to hearing from long-term high volume listening.

Cleaning dynamics and maintenance connector

Before you go into software settings, make sure that the physical paths of sound are not contaminated. In your jeans pocket, your smartphone collects pile and dust that clogs the grid of a conversational speaker and a multimedia emitter, a common reason for sound to become deaf and quiet.

Use a soft toothbrush or a special sticky tape (blu-tack) to clean your mouth, as moisture from your breath will settle inside and can cause corrosion of the membrane, and avoid using sharp metal objects that can pierce the safety net and damage the speaker.

The 3.5mm connector also requires maintenance. The oxidation of the contacts causes cod, noise, or complete loss of sound in one of the channels, which can be cleaned with a wooden toothpick, neatly removing visible dirt, and then blown with compressed air. If the oxidation is strong, you may need a special contact fluid, but this is a procedure for advanced users.

💡

Regular physical cleaning of audio compartments restores up to 30% of the lost volume without any software changes.
