How to improve Xiaomi headphones: from software settings to hardware improvements

Xiaomi headphones are some of the most popular wireless headsets on the market due to their combination of price, quality and functionality. However, even top-end models like the Xiaomi Buds 4 Pro or AirDots 3 Pro sometimes disappoint with sound: insufficient bass, “empty” sound of medium frequencies or weak detail, the reasons can lie in both factory settings and hardware limitations.

In this article, we’ll look at 10 working ways to improve sound, from basic smartphone settings to advanced headphone modifications, how to find the best equalizer, which codecs to use for minimal delays, how to clean speakers, and even how to replace earpieces for better noise insulation. All methods have been tested on Xiaomi models from 2020 to 2026 and are compatible with most Android devices.

Important: Some of the ways require root rights or earbuds, which we've marked with special warnings, start with simple steps and only get to the hard ones if you don't like the result.

1. Optimizing Bluetooth settings on a smartphone

Sound problems are often not with the headphones themselves, but with how your smartphone transmits the audio signal, starting with the basic Bluetooth settings and codecs.

The first thing to check is the Bluetooth version on your device. For example, Xiaomi 13 Pro supports Bluetooth 5.3, and budget models like Redmi Note 12 can be limited to Bluetooth 5.0. The newer version, the more stable the connection and the higher the bitrate. → The phone. → Bluetooth version.

Next, you can choose the audio codec. Android is the default. SBC (Subband Coding, which provides minimal latency but not the highest quality:

• 🎵 AAC — Balanced codec, supported by all Xiaomi headphones (ideal for Apple Music and YouTube).
• 🎧 aptX HD — Best quality for Android, but requires support for headphones (there is in Xiaomi Buds 4 Pro and newer).
• 🔊 LDAC — Maximum bitrate (up to 990 kbps), but can cause stuttering on weak smartphones.

To change the codec:

1. Put the headphones on the phone.
2. Open Settings → Connected devices → Settings gear next to the headphones.
3. Select the item Sound Quality or Audio Codec (name depends on firmware).
4. Experiment with codecs by testing the sound on the same song.

⚠️ Attention: Codec LDAC on budget smartphones (for example, Redmi) 10A) It can cause a break in sound. If you hear a crack, go back to the sound. AAC.

2. Equalizer setting: ready-made presets for different genres

The factory equalizer settings in Xiaomi headphones are often smoothed to please most users, meaning that the bass is muted and the high frequencies are not always clear, and you can fix this with an integrated or third-party equalizer.

If you have a smartphone MIUI, Use the built-in equalizer:

1. Open the Music (or Mi Music) app.
2. During playback, tap the Equalizer icon (three stripes).
3. Choose a preset or create your own by moving the sliders.

For more flexible customization, install Wavelet (free on Google Play) which supports automatic calibration for your headphones and has ready-made profiles for different genres.

Tip: After setting up your equalizer, listen to a track with a wide dynamic range (for example, "Bohemian Rhapsody" - Queen or "Clair de Lune" - Debussy) to assess the changes. If the sound has become "dirty" - reduce the amplification at extreme frequencies.

💡

Wavelet app has an Auto feature EQ, It automatically adjusts your headphone model. → Headphones → Xiaomi → [model].

3. Cleaning speakers and grids: when the sound gets quieter

Over time, the earpieces and headphones accumulate dust, earwax and small debris, resulting in muffled sound, especially at high frequencies, and clean up every 3 to 6 months, depending on the intensity of use.

You'll need:

• 🧻 Cotton swabs (better children - they are thinner).
• 💧 Alcohol wipes or isopropyl alcohol (70% and higher).
• 🔦 Lantern (for illumination of hard-to-reach places).
• 🧲 Magnetic tip (optional, to remove metal particles).

Step-by-step:

1. Take off the slacks (if they are removable).
2. Carefully walk with a dry cotton swab along the speaker grid, rotating it. Don't push it, the membrane is thin.
3. To remove the greasy spots, moisten the stick with alcohol and repeat the cleaning. Don't drip the liquid directly onto the speaker!
4. Blow the headphones with dry air (you can use a can of compressed air for equipment).
5. For hard-to-reach places, use a toothpick wrapped in cotton.

⚠️ Warning: Never use sharp objects (needles, knives) to clean - it is almost guaranteed to damage the speaker membrane.If the mesh is heavily contaminated and not cleaned, it is better to contact the service center.

4. Replacement of earpieces: how to improve noise insulation and bass

Ambushes (silicon or foam tips) directly affect the quality of sound insulation and, as a result, the perception of bass. Standard bulges from Xiaomi often are too rigid or loosely attached to the ear, which loses up to 30% of the low frequencies.

When choosing new embroideries, pay attention to:

• 🎯 Material: Silicone is versatile, but can rub with prolonged wear. Memory foam is better insulated, but requires compression before putting on. Hybrid (silicone) + stains are the best option for most.
• 📏 Size: Size larger if standard ones fall out. To check the density, press the earbud against your ear - if you hear external sounds, the earbuds are too small.
• 🔊 For basses suitable ambushes with a deep central part (for example, SpinFit) CP100).

Recommended brands for Xiaomi:

• 🥇 SpinFit – Best Price/Quality Rate, Suitable for AirDots and Buds.
• 🥈 Comply Foam – Premium foam boobys, improve bass by 20-40%.
• 🥉 Sony Hybrid – universal, suitable for most liners.

How to replace the chords:

1. Remove the old tips by pulling them aside (don't pull the wire!).
2. Wear new ones, making sure they sit tightly on the soundtrack.
3. For foam earpieces, squeeze them for 10-15 seconds before putting them on so they take the shape of an ear.

💡

Viper4Android It only works on Android 10 and below without any further manipulation. Newer versions of Android will require the Audio Compatibility Patch patch in Magisk.

Hardware modifications: replacement of speakers and passive radiators

If the software is exhausted and the sound is still not good, then the hardware is fine-tuned, which is suitable for advanced users because it requires disassembling headphones and risks losing warranty, but the results may exceed expectations: for example, replacing speakers in Xiaomi AirDots with Knowles or Beryllium improves detail by 40-50%.

What can be modified:

• 🔊 Dynamics: Replacement with a model with a beryllium membrane (for example, Tin Hifi) P1) Adds clarity at high frequencies.
• 🔋 Passive radiators: Installing copper or aluminum radiators improves bass due to resonation (suitable for Xiaomi Hybrid Pro).
• 🧲 Magnets: Replacing neodymium magnets with more powerful ones increases speaker sensitivity.
• 🔌 Wires: In wired models, replacing a standard cable with a silver or copper cable OFC reduces interference.

Step-by-step instructions for replacing speakers (on the example of Xiaomi AirDots 3 Pro):

1. Carefully place the top headphone cover with a plastic mediator (not a knife!).
2. Remove the old speaker by remembering the polarity of the contacts.
3. Install a new speaker by fastening it with heat glue.
4. So, make sure that you have no noise (these are not the ones that are in the air).

Where to buy spare parts:

• AliExpress is a search for “Xiaomi Buds 3 Pro driver” or “Knowles 33518”.
• eBay is for rare speakers (like Beryllium).
• Local radio parts stores - for wires and radiators.

⚠️ Attention: Disassembly of headphones is not warranty. If you are not sure about your soldering skills, contact the master. The average cost of replacing speakers in the service is 1500-3,000 rubles.

7. Alternative firmware for headphones (on the example of AirDots)

Some Xiaomi headphone models (such as AirDots) 1/2/3 or Buds 3) It supports alternative firmware that unlocks hidden features, such as improved equalizer, aptX support, and even gesture customization.

What custom firmware does:

• 🎛 Extended equalizer with 10 lanes (instead of 5 in stock firmware).
