How to Choose and Customize Xiaomi Headphones for Better Sound: The Complete Guide

The sound quality of Xiaomi headphones depends not only on the model, but also on the right setup. Even budget Mi Earbuds can sound much better after adjusting the equalizer and choosing the right profile. However, many users face problems: too quiet bass, distorted high frequencies or imbalance between the left and right channels. In this article, we will discuss how to choose the best model of headphones for your tasks (music, games, calls) and customize the sound through built-in MIUI tools or third-party applications.

We will focus on hidden Bluetooth codec settings (AAC, aptX, LDAC), which directly affect the quality of audio transmission, but are often ignored by users. Also compare popular Xiaomi headphone models in key parameters: resistance, frequency range and noise reduction support. If you want to get the most sound from your Redmi Buds or Xiaomi FlipBuds, this guide will help you avoid typical errors and unlock the potential of the device.

Why Xiaomi Headphones May Sound Bad: The Main Reasons

Most often, the problem with sound is not due to a defect in the headphones, but to the wrong settings of the smartphone or the accessories themselves.

• 🔊 Non-optimal Bluetooth codec: By default, many Xiaomi smartphones use SBC — It's the simplest codec with low bitrate, and it causes quality losses, especially at high frequencies.
• 🎛️ Standard equalizer: B MIUI By default, a flat profile is enabled without amplifying bass or medium frequencies, making the sound "empty".
• 📱 Energy saving limitations: Ultra-economic battery mode automatically reduces Bluetooth stream quality to reduce charge consumption.
• 🔋 Low headphone charge: At less than 20%, many Xiaomi models artificially turn down the volume to save energy.

Another common mistake is using high-resistance headphones (such as the Xiaomi Hybrid Pro HD with 32 ohms) without an amplifier, in which case the smartphone can not provide enough voltage, and the sound becomes quiet and distorted. Check the specifications of your model before buying!

⚠️ Warning: If you hear wheezing or interrupting sound at high volume, this may indicate membrane overload.Lower volume or turn on the limiter in the sound settings (Settings) → Sound. → Additionally. → Volume limitation).

How to choose Xiaomi headphones for your tasks: comparison of models

Xiaomi’s line of headphones includes more than 20 models, from the budget Redmi Buds 3 Lite to the flagship Xiaomi Buds 4 Pro with active noise cancellation. To avoid making a mistake with the choice, focus on the main use cases:

For games, it is better to choose low-latency models (aptX LL or LC3), for example, Xiaomi Buds 4 Pro (latency ~55 ms). If you want noise reduction, pay attention to FlipBuds Pro with a hybrid ANC system. For wired headphones, impedance is critical: models with 16-32 ohms will be suitable for smartphones, and 100+ ohms will require an amplifier.

Setting up Bluetooth codecs for better sound

By default, Xiaomi smartphones (starting with MIUI 12) support multiple Bluetooth codecs, but don't always choose the optimal one automatically.

1. Open the settings → Connected devices.
2. Click on the gear icon next to the connected headphones.
3. Choose Sound Quality → Codec.
4. Set priority in order: LDAC → aptX Adaptive → AAC → SBC.

Let’s see what codec is suitable for:

• 🎵 LDAC: Maximum quality (up to 990 kbps), but high battery consumption. FLAC or WAV.
• 🎮 aptX Adaptive: Optimal for games (low latency) and video. Automatically adjusts to the communication conditions.
• 📞 AAC: Good for calls and podcasts. Energy efficient, but yields LDAC detailing.
• ⚠️ SBC: Outdated codec with low bitrate. Use only if others are not supported.

⚠️ Attention: Codec LDAC It can cause a sound interruption in a weak Bluetooth signal (for example, if the smartphone is in your pocket and you move), in which case switch to aptX or AAC.

💡

If there is no LDAC or aptX in the list of available codecs, update your headphone firmware through the Mi Home or Xiaomi Earbuds app. New versions of the software often add support for modern codecs.

Optimization of the equalizer: ready presets for different genres

The built-in equalizer in MIUI allows you to fine-tune the sound, but many users do not know where to start. Here are ready-made presets for popular music genres (values for a 10-band equalizer, where 0 dB is a neutral position):

To apply the preset:

1. Go to Settings → Sound → Equalizer.
2. Select User-Selected.
3. Manually set the values for each band (see table).
4. Keep your profile under a convenient name (such as Hip Hop).

For games, it is recommended to turn off the equalizer altogether or use minimal corrections, since audio processing adds a delay. If you play through Xiaomi Buds 4 Pro, turn on Low Latency mode in the headphone settings.

Hidden sound settings in MIUI: what can be enabled

MIUI hides a few useful options that are not visible in the main menu, so you can activate them:

1. Turn on Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the Network → Quality Bluetooth audio section.

Options are available here:

• 🔄 Bitrate Priority: Set Quality for Music or Balance for Calls.
• 🎧 Monoconnection: Allows you to use only one headphone (useful for saving charge).
• 📊 Show bitrate: Displays the current data rate to the notification panel.
• 🔇 Absolute volume: Synchronizes volume level between phone and headphones.

Another hidden feature is flashing headphones through Mi Home. For example, Redmi Buds 4 Pro has alternative firmware with improved ANC or modified audio profile. Official firmware can only be downloaded through Xiaomi's Chinese servers, so use a VPN with China region when upgrading.

Sound problems and their solutions

Even after setting up, you can have typical problems, and here's how to fix them:

If Xiaomi headphones are not defined by a smartphone:

1. Remove them from the list of associated devices (Settings → Connected devices).
2. Reset the headphones to factory settings (usually by pressing the button for 10 seconds).
3. Reboot your smartphone and reconnect.

⚠️ Warning: If the sound is lost after updating the headphone firmware, reset via Mi Home and reconnect them. In rare cases, you may need to roll back to the previous version of the software (instruction in the spoiler above).

Third-party applications for fine-tuning sound

The built-in MIUI tools are limited, so you should use third-party apps for advanced customization.

• 🎛️ Wavelet: Free equalizer with support LDAC It has a profile base for popular Xiaomi models.
• 🔊 Poweramp Equalizer: 10-band equalizer with preamplifiers. Suitable for music fans.
• 🎧 ViPER4Android: Advanced audio processing (convolvers, dynamic compression) requires Magisk to work properly.
• 🎵 Neutron Music Player: Built-in 32-bit equalizer and support DSD-format.

To install ViPER4Android on Xiaomi:

1. Get root rights through Magisk.
2. Download the latest version of ViPER with XDA Developers.
3. Install the driver through Magisk Module.
4. Set up an in-app profile (it is recommended to start with Viper) DDC and FIR-filter).

If you don’t want to get root, use Wavelet – it works without superuser rights and has built-in profiles for Xiaomi Buds 3/4 Pro and Redmi Buds.

💡

For most users, a combination of the built-in MIUI equalizer + Wavelet application is enough. ViPER4Android is only suitable for audiophiles with root rights.
