Xiaomiβs wireless headphones are not only a stylish accessory, but also a precise device that requires regular maintenance. Earwax, dust and moisture accumulate over time in speakers, grids and body, which leads to deterioration of sound, distortion of bass or complete loss of communication in one of the headphones. Especially relevant is the problem for models with an open design (AirDots Pro 2, Buds 3 Pro), where sulfur penetrates deeper due to the lack of silicone embushures.
Many users are afraid to clean their headphones themselves for fear of damaging the membrane or electronics. However, with the right approach, the procedure takes no more than 10 minutes and prolongs the life of the device for years. This article provides proven cleaning methods adapted to specific Xiaomi models, as well as tips for prevention to help avoid re-contamination.
Important: Cleaning methods for TWS-Headphones (e.g. Redmi Buds 4 Active) and overhead models (Xiaomi FlipBuds Pro) are different. We'll take both options into consideration the nuances of the design. If your headphones have already lost sound, don't throw them away: 80 percent of the time, the problem is solved by deep cleaning, not replacing them.
Why Sulfur is Dangerous for Xiaomi Wireless Headphones
Earwax is not just dirt, it's an abrasive substance that, when it's drying, becomes hard, and it settles on three critical areas in headphones.
- π Dynamic and protective grid - sulfur clogs microholes, which makes the sound muffled, and the bass disappears.
- πΆ Infrared/optical sensors (in Wear Detection models) β pollution leads to false positives (earphones βthinkβ theyβre removed).
- π Charging contacts - sulfur oxidizes the metal, which causes one earphone to stop charging.
According to service centers, 65% of complaints about the βdefaultβ headphone Xiaomi AirDots associated with clogging sulfur, not with the breakdown of electronics, and users often confuse the symptoms: for example, if the headphone is quieter, this is not always a problem with Bluetooth β most often the fault of sulfur on the membrane.
Another danger is corrosion, which contains fatty acids that, when exposed to moisture (afterwards or rain), corrodes copper contacts, especially for low-cost models (Redmi Buds 3 Lite), where moisture protection is minimal (IPX4).
β οΈ Warning: If the sound has not recovered after cleaning, check the headphones for software failure. To do this, reset them to factory settings via the Bluetooth menu on your smartphone (press the button on the case for 15 seconds).
What you need to clean: a list of tools
Don't use any homemade tools like toothpicks or needles, they scratch the plastic and tear the speaker's safety net. Here's a safe cleaning kit:
- π§΄ Alcohol wipes (70% isopropyl alcohol) - for disinfection of the body and removal of fatty spots.
- π¨ Soft brush (for example, for watercolor or makeup) β to sweep dust from hard-to-reach places.
- π§² Bluetooth magnifier (or magnifying glass) β will help you see microcracks or deep contamination.
- π§ Cotton swabs (better children's, with an elongated tip) - for cleaning the depressions.
- π₯ Cold blower hair dryer β to blow dust out of speakers (only for models with a IPX5+).
A special sticky paste (such as Sony Earbud Tips Cleaning Putty) is suitable for deep cleaning of speakers, but it is difficult to find in Russia. The alternative is plasticine (without dyes!), which can be slightly stretched and pressed to the grid to "pull out" the sulfur.
If the headphones have removable earbuds (Xiaomi FlipBuds Pro), prepare a soap solution (warm water + baby soap) to soak them. Don't use aggressive detergents - they destroy silicone!
Step-by-step: how to clean Xiaomi headphones from sulfur
The cleaning process depends on the design of the headphones. Here's a general-purpose algorithm that works for most people. TWS-models (AirDots, Buds), as well as individual recommendations for invoices (FlipBuds).
1. Preparation and external cleaning
Start by turning off the headphones from power and removing them from the case.If the model supports Wear Detection (like Buds 3 Pro), turn off this feature in the Mi Home app so that the sensors don't go off during cleaning.
Sequence of action:
- Wipe the body with a dry microfiber wipe to remove dust and sweat.
- Wet the cotton swab in isopropyl alcohol (not ethanol!) and gently walk along the seams and joints.
- To clean the charging contacts, use an eraser (washing gum) - it will remove oxides without risking damage to the coating.
Cleaning of speakers and protective grid
This is the most important part. Never blow into the speaker with your mouth - saliva contains enzymes that accelerate corrosion!
Cleaning methods:
- π΅ Sticky paste/plasticine: warm up the piece in your hands, press it against the net for 10 seconds, then gently remove it. Repeat 2-3 times.
- π¨ Dryer on a cold blower: direct the jet of air at an angle of 45Β° To the speaker (distance - 5 cm). Do not use hot air!
- π§Ή Soft brush: brush the dust off the grid with movements "from center to edges".
For models with open speakers (AirDots 3 Pro), a soft bristling toothbrush dipped in alcohol is suitable. The movements should be circular, without pressing.
βοΈ Checklist before cleaning speakers
3. Cleaning of bulbulges and silicone tips
If your headphones have removable earbuds (FlipBuds Pro, Buds 4), you can soak them in soap solution for 15-20 minutes. For non-removable airdots, use a wet napkin dipped in alcohol.
Important:
- Do not rub embusures with abrasive materials (such as paper towels) β they scratch silicone.
- After washing thoroughly dry the tips in the air (not a hairdryer!).
- If the embroideries have lost elasticity, replace them - the original sets are sold in the Mi Store.
4.Cleaning the case for charging
The charge case accumulates dust and pile, which then gets back into the headphones.
- Remove the headphones and wipe the inner surface with a dry wipe.
- To clean the contacts, use a cotton swab dipped in alcohol.
- If the case has rubber legs, wash them with soap solution - they often stick due to accumulated dirt.
π‘
If the contacts in the case are oxidized (green coating appeared), wipe them with citric acid diluted in water (1 tsp. per 50 ml). After treatment, wash with alcohol and dry for 2 hours.
5. Post-cleaning check
After cleaning, be sure to test the headphones:
- π Check the sound balance β if one earphone gets louder, itβs possible the sulfur isnβt completely removed.
- πΆ Make sure the Bluetooth connection is stable (no breaks).
- π Check charging β both headphones should charge equally fast.
If the sound is still distorted, repeat the cleaning of the speakers or contact the service. In 10% of cases, the problem is a membrane damage that requires a replacement speaker.
Table: features of cleaning for popular Xiaomi models

|---|---|---|---|
| Xiaomi AirDots (all versions) | Inlays (open) | The speaker grid is easily clogged, use a sticky paste or a hair dryer. | 1 time 2 weeks |

What not to do when cleaning headphones Xiaomi
Some folk methods can permanently ruin headphones.
- π« Wash under water, even if the model has protection IPX4, Water penetrates the microphone and speaker.
- π₯ Use hot air (dryer, radiator) - plastic is deformed, glue on the embushures melts.
- π§ Clean with salt or soda - abrasives scratch the protective net and body.
- π Charge during cleaning β alcohol can cause short circuit on contacts.
Myths you shouldn't believe:
- βA toothpick will help remove sulfur from the speakerβ β In fact, it pushes the sulfur deeper and tears the net.
- "Hydrogen peroxide disinfects headphones" β It corrodes silicone embroideries and leaves a white coating.
- "You can clean with ear sticks with a limiter" β The limiter does not protect against pressure on the membrane.
β οΈ Note: If after cleaning the headphones appeared crunch or crack, you probably damaged the protective membrane of the speaker. In this case, only replacing the speaker in the service center (cost - 800 to 2000 rubles) will help).
Prevention: How to reduce headphone pollution
Cleaning regularly is good, but it's even better to prevent too much pollution.
- π§Ό Wash your headphones after exercise β sweat speeds up the oxidation of contacts.
- π§ Store in a case β open storage attracts dust.
- π Change the bulges every 3-6 months β over time they lose shape and let more sulfur through.
- πΏ Do not use headphones in the shower or pool, even if they have protection. IPX7.
For models with active noise cancellation (Buds 3 Pro), it is recommended to turn off the ANC in dusty rooms - the system sucks in air along with dirt particles.
Athlete advice: If you're in the gym, apply a thin layer of Vaseline (no fragrances!) to your earbuds, which will reduce sulfur and sweat adhesion. After exercise, just wipe your headphones with a napkin.
