Earwax is a natural secret that protects the ear canal, but it becomes a real problem for owners of Xiaomi AirDots, Redmi Buds or Mi True Wireless. Over time, sulfur accumulates on silicone inserts, speaker grids and even inside the sound channel, worsening sound quality, reducing volume and creating discomfort when wearing. According to research, up to 78% of wireless headphone users experience this problem in the first 6 months of operation.
Cleaning Xiaomi headphones requires caution: improper actions can damage the speaker membrane, disrupt the tightness of the case or even disable the device. In this article, we will analyze 5 proven cleaning methods – from household improvised products to professional kits, and also tell you which Xiaomi models are most vulnerable to contamination due to design features (for example, AirDots Pro 2 with an open speaker grille).
Why Earwax is Dangerous for Xiaomi Headphones
Earwax is made up of fats, proteins and dead skin cells, and when it comes into contact with silicone liners, it forms a sticky coating that:
- 🔊 The sound is worse – sulfur clogs the speaker grid, reducing the volume by 15-30% (according to tests of the SoundGuys laboratory).
- 🦠 Promotes the growth of bacteria – a moist environment is ideal for the reproduction of Staphylococcus aureus and fungi.
- 🔋 Accelerates battery discharge – contaminated contacts of the charging case increase resistance.
- 🚫 May cause allergies – a mixture of sulfur and dust irritates the skin of the ear.
Open-acoustic models like the Xiaomi FlipBuds Pro or Mi Neckband Bluetooth are particularly vulnerable, and their speakers are not protected by a sealed body, so sulfur penetrates deeper, while the fully wireless AirDots 3 Pro suffers from a raid on the case contacts, leading to charging problems.
⚠️ Warning: If the earphones start beeping or the sound becomes distorted after cleaning, this is a sign of membrane damage, in which case professional repair is required - self-attempts to "blow" the speaker can aggravate the problem.
What you need to clean: tools and tools
Before you start cleaning, prepare the necessary materials. Do not use sharp objects (toothpicks, needles) or aggressive solvents (acetone, alcohol concentration above 70%) - they will damage silicone and plastic.
| Tool/tool | What do you need? | Where to buy | Cost (₽) |
|---|---|---|---|
| Cotton swabs (with limiter) | Cleaning of liners and shells | Pharmacy, supermarket | 30–100 |
| Toothbrush (soft) | Removal of sulfur from speaker grille | Household goods store | 50–150 |
| Salicylic alcohol (1–2%) | Disinfection and dissolution of fats | Pharmacy | 20–50 |
| Special headphone brush (e.g. Baseus Cleaning Kit) | Deep cleaning of speakers and contacts | AliExpress, Wildberries | 200–500 |
| Sticky cleaner (e.g, 3M Post-it Cleaning Putty) | Removing dust from hard-to-reach places | Stationery, Ozon | 150–300 |
For models with active noise cancellation (ANC), For example, Xiaomi Air 2 Pro or FlipBuds Pro, you will need a compressor with a return valve (cost from 800). ₽) They're used to blow out microphone holes, and they get clogged, and they get out of order. ANC.

Before cleaning, take photos of the headphones on a white background – so you will notice all the contaminated areas that you may have missed during a visual inspection.
Step-by-step: how to clean Xiaomi headphones from sulfur
Follow the algorithm according to the level of contamination. For easy plaque, dry cleaning is enough, for old deposits, special tools are required.
1. Dry cleaning (for mild contaminants)
- 🧹 Remove the liners (if they are removable, like the Mi Hybrid Pro) and rinse them with warm water and soap. Dry for at least 2 hours.
- 🎵 Wipe the body with a dry microfiber wipe (for example, for glasses.
- 🔍 Clean the speaker grille with a soft toothbrush. Hold the earbud down so that the sulfur doesn't penetrate deeper.
2. Wet cleaning (for medium contaminants)
- 💧 Moisten the cotton swab in salicylic alcohol (1-2%) and gently wipe the silicone liners!
- 🧼 For plastic parts, use a soapy solution (1 drop of liquid soap per 50 ml of water). Apply with a wet wipe, then wipe dry.
- 🔌 Contacts of the charging case clean with a cotton swab dipped in isopropyl alcohol (90%).
3. Deep cleaning (for severe contaminants)
If sulfur has penetrated the speaker:
- Use a special brush with a soft pile (for example, from the Baseus set).
- To remove sulfur from the sound channel, use a sticky cleaner. Roll down a small ball, press against the hole and pull over.
- If the sound is muffled, blow the speaker with a compressor with a return valve (pressure not more than 0.5 bar).

⚠️ Never immerse your headphones in water completely, even if they are protected by standard. IPX4 (Like Redmi Buds 3 Pro, prolonged contact with liquid will damage electronic components. Maximum moisture exposure time is 10 seconds.
Features of cleaning for popular Xiaomi models
The design of the headphones affects cleaning methods, and let's look at the nuances for the most common models.
Xiaomi AirDots (all generations) and Redmi Buds
These headphones have an open speaker grille, so sulfur can easily penetrate inside.
- 🔊 Speaker: Clean only dry (brush or sticky cleaner) Wet cleaning is allowed only for the case.
- 🔋 Case contacts: wipe alcohol monthly - oxidation leads to poor charging.
- 🎧 Inlays: removable, you can wash in soapy solution.
Xiaomi FlipBuds Pro and Air 2 Pro (c) ANC)
Active noise cancelling models have additional microphone holes that become clogged with sulfur and dust.
- 🎤 Microphones ANC: blow the compressor every 2 months. The clogging leads to a whistle when you turn on the noise cancellation.
- 🔄 Grid speaker: use a brush with ultra-soft pile, so as not to damage the membrane.
- 🛡️ Protection from Moisture: Despite the IP54, Avoid direct hitting of liquid on touch buttons.
Mi True Wireless 2 and AirDots 3 Pro
These models have a semi-open acoustic architecture, which makes cleaning difficult.
- 🔍 Sound channel: only use dry methods to clean. Humidity can damage the driver.
- 🔋 Wireless charging: wipe the back of the case with alcohol - dirt interferes with induction charging.
- 📦 Storage: Keep the case closed so that dust does not settle on the contacts.

What can not clean headphones Xiaomi: common mistakes
Many "folk" cleaning methods lead to breakdowns.
| Prohibited method | Effects of consequences | The right alternative |
|---|---|---|
| Toothpicks, needles, paper clips. | Puncture of the membrane, scratches on the body | Soft toothbrush or cotton swab |
| Acetone, gasoline, solvents | Eating away plastic and rubber | Salicylic alcohol (1–2%) or soap solution |
| Immersion in water | Short circuit, battery failure | Wet cleaning with a napkin with a minimum amount of liquid |
| Hazette | Deformation of silicone liners, detachment of glue | Natural drying at room temperature |
| Chewing gum for cleaning | Residues of sticky substance clog the speaker | Sticky cleaner (e.g, 3M Post-it Cleaning Putty) |
Hydrogen peroxide is especially dangerous, oxidizing the metal contacts of the case, which leads to charging problems. Also avoid ultrasonic baths, which are often recommended for cleaning: vibration can damage the adhesive connections inside the headphones.
💡
The most common reason for the headphones to break after cleaning is damage to the speaker membrane. If after the procedure there is wheezing or the sound became quieter, immediately stop using and contact the service.
How often should you clean your Xiaomi headphones?
The frequency of cleaning depends on the intensity of use and the individual characteristics of earwax.
- 📅 Daily: wipe the case and liners with a dry wipe after use.
- 🔄 Once a week: Clean the speaker grille with a soft brush.
- 🧼 Once a month: wet cleaning of silicone liners and case contacts.
- 🔍 Once every 3 months: deep cleaning with purge (for models with a ANC).
If you use headphones during sports or in dusty conditions (for example, on a construction site), cleaning should be done 1.5-2 times more often. To check the degree of contamination, use a flashlight: direct light to the speaker grille - if you see a raid, it is time to clean.
Signs that the headphones are in urgent need of cleaning:
- 🔊 The sound became quieter or wheezing appeared.
- 🤢 The smell of the liners is bad.
- 🔋 Case is not charging headphones well.
- 🎤 People complain about the poor hearing of your voice.
Prevention: How to prevent contamination of headphones
Compliance with simple rules will help reduce the frequency of cleaning and prolong the life of headphones:
- Store it in a case. Open storage causes dust to accumulate on the contacts and the speaker grille.
- Use a case case case that protects against scratches and reduces dirt (such as Spigen or Baseus cases).
- Change the liners every 6 months. Silicone loses elasticity over time and accumulates bacteria. Original removable liners for Xiaomi cost from 200 ₽.
- Avoid using it during sleep, during which time earwax is more active and the headphones are not ventilated.
- Rub your ears before use. Remove excess sulfur with a cotton swab (but not deeply!).
For models with touch control (for example, AirDots 3 Pro) it is additionally recommended:
- 👆 Press the touch zones with your dry fingers – sweat and fat leave traces.
- 🔄 Once a month, wipe the sensors with a napkin soaked in alcohol.
