How to set up headphones on Xiaomi Redmi 8 Pro

Xiaomi Redmi 8 Pro is equipped with a high-quality audio track that allows you to enjoy music and movies in high resolution. However, standard settings often do not reveal the full potential of your equipment, whether it is expensive wired headsets or modern wireless models. The correct configuration of audio output can dramatically change the perception of sound, adding depth to bass and clarity to high frequencies.

Device owners often face a situation where, after updating the firmware or connecting a new accessory, the sound becomes quieter or there are extraneous noises. This does not always indicate a breakdown. Most often, the problem lies in software conflicts or incorrectly selected equalizer profiles. It takes only a few minutes to properly adjust the audio interface, but the result will be happy for you all the time.

In this article, we will take a closer look at all the steps of audio optimization, including the 3.5mm wired connection and the Bluetooth device setup, and how to activate hidden MIUI features that are not normally available to the average user.

Basic setup of wired headphones

When you connect a wired headset to a 3.5 mm connector, the system automatically determines the type of device. However, to achieve the best sound quality, you need to manually check the output parameters. Go to the Settings menu and select the Sound and Vibration section. This is where the main volume sliders are, but we're interested in a deeper setup.

It's important to consider that the resistance of the coils varies from one headphone to another. If you use professional audio equipment with high impedance, standard amplification may not be enough, in which case the sound will be quiet and devoid of dynamics. For conventional consumer models, the default settings are often excessive, which leads to wheezing at maximum volume.

⚠️ Note: Using third-party amplifiers or adapters with unsupported resistance can overheat your smartphone audio chip.

To fine tune the frequencies, you need to use a built-in equalizer. The standard set of presets suits most users, but manually adjusting gives you the best result. Try raising the frequencies slightly in the 60-250 Hz range for volume bass and adding clarity in the 4 kHz area for vocals.

💡

Use high-quality Type-C to 3.5mm adapters with built-in DAC (DAC) if your smartphone model does not have a separate audio chip.

Optimizing Bluetooth Connection

Wireless technology transmits sound differently than cable. When setting up Bluetooth headphones on Redmi 8 Pro, it becomes critical to choose a codec. The system supports various compression protocols, from basic SBC to advanced aptX and LDAC. The sound quality depends on which codec is chosen for the pair.

To check and change the codec settings, you need to activate the developer menu. Go to About Phone and quickly click on the MIUI build number seven times. Once the notification appears, go back to the main settings, select Additional and go to Developer. Find the Bluetooth section and select the desired codec from the list.

• 🎧 SBC — Basic codec that allows compatibility with all devices, but with loss of quality.
• 🎵 aptX is a standard from Qualcomm that offers a balance between quality and stability of the connection.
• 🎼 LDAC — Sony technology transmits three times more data than standard Bluetooth for Hi-Res audio.
• 🔋 AAC — Optimized for Apple devices, but works well on Android, saving battery life.

Remember, codec support is not just dependent on the smartphone, but also on the headphones themselves. If your headphones don't support LDAC, choosing this item in your phone's settings won't improve sound, or even cause audio and video to become out of sync. Experiment with settings by listening to your favorite tracks.

Use of Dolby Atmos and Sound Effects

Redmi smartphones often feature Dolby Atmos surround sound technology, which creates virtual sound space to make sound more immersive, activate it through a menu of sound effects, analyzes the content being played and adapts the frequencies in real time.

The audio effects menu also has the option "Mi Sound Enhancer" available, which is designed to improve the quality of compressed audio files. When activated, the processor further processes the signal, recovering lost parts during compression. However, on some tracks this can lead to artificial sound, so it is recommended to test the on and off options.

The overlay of Dolby Atmos, equalizer and Mi Sound Enhancer can create a porridge of sounds where detail is lost. The optimal scenario is to use one main effect (for example, Dolby) and easy equalizer adjustment.

Solving problems with quiet sound

One of the most common complaints users have is the low volume. If the sound seems quiet after you plug in the headphones, the first thing you do is check if you have "Hearing Safety" or volume limits on third-party apps, and sometimes the system artificially lowers the signal level to protect your ears.

Also, the problem may be contamination of the speaker grid or connector. Dust and pile can physically block the output of sound or disrupt the contact of the plug. Carefully clean the 3.5 mm connector with a dry soft brush. Do not use metal objects so as not to damage the contacts.

If the software methods don't help, you can try resetting your Bluetooth settings. To do this, delete all saved devices and restart your smartphone. In some cases, resetting your network settings helps, but remember that this will also delete stored Wi-Fi passwords.

⚠️ Warning: Do not try to disassemble the headphone jack yourself.This is a complex procedure that requires soldering equipment, and it can lead to the complete failure of the audio module.

Customization of the microphone in headphones

The quality of voice transmission when speaking depends not only on the speaker, but also on the microphone of the headset. MIUI has a noise reduction function that sifts out background noise, and you can find it in the audio settings or in a special security application, activating this feature is especially useful when talking on the street or in transport.

For voice recording or voice recording, it is important to position the microphone correctly. Microphones built into wired headphones are usually located on a wire. Make sure they are not covered by clothing. For Bluetooth headsets, it is important that the device is pressed tightly against the ear for better bone vibration (if such technology is used) or clear voice capture.

• 🎙️ Check the permissions for applications in the Privacy section.
• 🔇 Make sure that during the conversation, the "Do Not Disturb" mode is not turned on".
• 📶 If you have poor communication, switch from VoLTE to standard voice call for stability.

If someone complains of echoes or interruptions, try turning off the voice enhancement function, and sometimes the noise-cancellation algorithms don't work properly and start cutting the beginning of a phrase or creating a robot effect.
