Xiaomi earbuds are some of the most popular gadgets, thanks to a combination of price, sound quality and design. But even the most reliable models (Redmi Airdots, Mi True Wireless Earbuds, Xiaomi Buds 4 and others) get dirty over time: earbuds accumulate sulfur, speakers are clogged with dust, and the body is covered with greasy marks. Improper cleaning can spoil the sound or even make the device fail – so it is important to know how to clean the earbuds safely and efficiently.
In this article, you will find step-by-step instructions for different types of pollution (from light dust to dried sulfur), tips for choosing tools and unique tips for caring for specific Xiaomi models that are not in the standard manuals, and we will also discuss what you should not do, which is a mistake made by 90% of users.
1.Why are Xiaomi headphones polluting faster than others?
Xiaomi headphone design has several features that accelerate the accumulation of dirt:
- 🔹 Open speakers in models such as Mi Hybrid or Redmi Buds 3 Pro – dust and moisture penetrate deeper than in closed counterparts.
- 🔹 Silicone bulges with porous structure (especially in Xiaomi Buds 4) are the perfect environment for bacterial reproduction.
- 🔹 Magnetic mounting in wireless model cases - attracts metal dust from the air.
- 🔹 Compact case with minimal gaps - dirt accumulates in joints and notches.
According to service centers, 7 out of 10 Xiaomi headphone failures are pollution-related, from turning down the volume to completely failing the microphone, and even newer models (2023-2026) lack dust protection above the top. IP4 — This means that particles larger than 1 mm can penetrate inside.
2.What you will need to clean: a safe toolkit
Before starting cleaning, prepare the following items (they can be found at home or bought in a hardware store for 100-300 rubles):
| Tool. | What do you need? | The alternative |
|---|---|---|
| Cotton swabs (thin, children's) | Cleaning of speakers and hard-to-reach places | Toothpick with cotton candy |
| Soft toothbrush (new!) | Removing dirt from speaker grid | Paint brush (synthetic) |
| Alcohol wipes (70% isopropyl) | Disinfection of the shell and bulges | Vodka or diluted medical alcohol |
| Adhesive tape (scotch) | Removal of dust from the cover | Sticky roller for clothes |
| Compressed air (cylinder) | Blowing dust from speakers | Dryer at minimum power (cold air) |
What NOT to use:
- 🚫 Water or soap solution - getting moisture into the speaker leads to corrosion of the membrane.
- 🚫 Sharp objects (needles, knives) - will damage the protective net.
- 🚫 Aggressive solvents (acetone, gasoline) - corrodes plastic and rubber.
- 🚫 Vacuum cleaner – can suck in small parts (for example, ambushes).
⚠️ Note: If your headphones have active noise cancellation (ANC), Like in Xiaomi Buds. 3T Pro, avoid strong mechanical impacts on microphones – they are located next to the speakers and easily damaged.
3. Step-by-step instructions: how to clean Xiaomi headphones
The cleaning process depends on the type of headphones, and below is a universal technique that is suitable for most models (Redmi Airdots, Mi True Wireless, Xiaomi Buds, etc.).
Remove the slacks (if they are removable)
Remove the headphones from the case (for TWS)
Prepare all tools
Disconnect the headphones from the power source-->
Cleaning of shell and mounts
1. wipe the body with a dry wipe made of microfiber (for example, for glasses) - this will remove greasy traces and dust.
2.Use an alcohol wipe for disinfection, but don't rub too hard - Xiaomi plastic can lose gloss.
3. Wash the bottles with warm water and soap (if removable), then dry for at least 2 hours before installing them back.
Cleaning of speakers and grids
1. Take a soft toothbrush and gently remove dust from the net in circular motions.
2.To remove earwax, use a cotton swab dipped in alcohol, but do not press - the sulfur should dissolve, rather than rub deeper.
3.If the dirt is not removed, use compressed air (hold the canister at a distance of 5-10 cm).
💡
For models with a hybrid speaker (for example, Mi Hybrid Pro) after cleaning, check the sound at 1 kHz — if there are wheezing, then sulfur hit the membrane.
Cleaning of the cover for TWS-headphone
1. Remove the large rubbish with a dry wipe.
2. To remove dust from the charging connector, use Scotch tape - glue it to the sticky side and gently run it through the contacts.
3. wipe the inside of the cover with an alcohol napkin, avoiding moisture on the contacts.
⚠️ Note: Xiaomi Buds 4 Pro and later cases have magnets for wireless charging.Do not use metal objects for cleaning - they can disrupt the polarization of magnets.
4.How to clean Xiaomi headphones from earwax: emergency methods
If the sulfur has dried up and is not removed by standard methods, try the following methods (suitable for Redmi Airdots 3, Mi Earphones Basic and other open-speaker models):
- 💧 Hydrogen peroxide (3%) - Apply 1-2 drops on a cotton swab and apply to the grid for 30 seconds.
- 🔥 Steam method – hold the headphones over hot water (not boiling water!) 1-2 minutes, then wipe with a dry wipe.
- 🧊 Freeze - put the headphones in a bag and place in the freezer for 1 hour. The sulfur will become brittle and crumble with a light tap.
Important: These methods are only suitable for wired headphones or TWS-protectionist IP54 and above (e.g. Xiaomi Buds) 3T For budget options (e.g. Redmi Airdots 2), use only dry methods.

5. Features of cleaning for popular Xiaomi models
Each Xiaomi headphone series has unique design features that affect the cleaning process.
| Model | Features of cleaning | What to avoid |
|---|---|---|
| Redmi Airdots (all versions) | The mesh speaker is very thin, clean only with a soft brush. The case is prone to accumulating dust in the hinges. | Do not use wet wipes for the case - the paint can be erased. |
| Xiaomi Buds 4 / 4 Pro | Removable bottles, you can wash with water, and there are air vents in the case that you need to clean with compressed air. | Do not press the touch panels when cleaning - they are sensitive to mechanical stress. |
| Mi True Wireless Earbuds 2 | The speakers are protected by a metal grid, you can use a toothpick with cotton wool. The microphones are located on the end. | Do not clean the microphones with alcohol - this worsens the sensitivity. |
| Xiaomi Hybrid / Hybrid Pro | Hybrid speakers require caution – sulfur often accumulates at the junction between high- and low-frequency emitters. | Do not use compressed air - you can damage the membrane. |
For models with active noise cancellation (ANC), Like the Xiaomi Buds. 3T Pro, after cleaning, it is recommended to reset the settings through the Mi Home app to restore the optimal microphone settings.
6.How often should you clean Xiaomi headphones?
The frequency of cleaning depends on the intensity of use and model:
- 📅 Daily – wipe the body with a dry wipe (especially if the headphones are used in the gym or on the street).
- 📅 Once a week – clean the earpieces and the speaker grid (for all models).
- 📅 Once a month – deep cleaning of the cover and contacts (for the purpose of cleaning the TWS-headphone).
- 📅 Every 3 months - disinfection with alcohol and checking microphones (for models with a ANC).
If you notice a deterioration in sound, an irregular noise or an unstable connection, this is a signal for an unscheduled cleaning. For example, in Redmi Buds 3 Pro, a buildup of dust on the contacts of the case can lead to intermittent charging.
💡
Not only does regular cleaning improve sound, it also extends the life of headphones by 30 to 50 percent, and service centers say 60 percent of the devices that have been repaired because of a breakdown simply require cleaning.
7.Typical mistakes when cleaning Xiaomi headphones
Even experienced users often make mistakes that lead to breakdowns.
- 🔌 Cleaning on headphones – this can cause contact closure, especially in touch-controlled models.
- 💦 Immersion in water – even if the headphones have protection IPX4, Long-term contact with water destroys the adhesives.
- 🔊 Using a vacuum cleaner – strong airflow can tear the speaker membrane (especially in the Mi Hybrid).
- 🧴 Applying alcohol to the speaker - dissolves the protective coating of the mesh, which leads to corrosion.
One of the most dangerous mistakes is to use toothpicks without cotton can pierce the membrane, which will lead to irreversible distortion of the sound, and if the sulfur is very dry, it is better to use special sticks with a limiter (sold in electronics stores).
8.Prevention: How to keep your headphones clean for longer
Compliance with simple rules will help reduce the frequency of cleanings and prolong the life of your headphones:
- 🎧 Store in a case – even if the headphones are wired, use a case to avoid getting dust.
- 🚿 Avoid moisture – after training or rain, dry your headphones 1-2 hours before cleaning the case.
- 🔄 Change the bottles – in Xiaomi Buds 4 and other models with removable nozzles, it is recommended to update them every 3-6 months.
- 📵 Do not share headphones – it is not only hygienic, but also prevents the entry of foreign bacteria.
For models with wireless charging (for example, Xiaomi Buds) 3T Pro) avoid placing the case on metal surfaces – this can disrupt the magnets and lead to poor contact when charging.
💡
If you often use headphones in dusty conditions (for example, on a construction site or in a workshop), buy protective filters for speakers (stand). ~200 rubles. They prevent particles from getting inside without making the sound worse.
