How to Clean Xiaomi Headphones From Sulfur: 5 Safe Techniques and Care Tips

Why Earwax is Dangerous for Xiaomi Headphones and How to Remove It Without Damage

Xiaomi headphones — whether wireless AirDots, Redmi Buds or wired models — accumulate earwax, sweat and dust over time. Not only does it make the sound worse, it can also make the device malfunction. The sulfur, when mixed with moisture, forms a sticky mass that clogs the speakers, lowers the volume and distorts the bass frequencies. In neglected cases, this leads to corrosion of contacts or break the microphone.

Sulphur cleaning is a careful procedure. Mistakes (such as using sharp objects or aggressive solvents) can damage the speaker membrane or protective mesh. In this article, we will discuss 5 proven cleaning methods that are suitable for all Xiaomi models, including the AirDots Pro 3, Buds 4 and Hybrid Pro. You will also learn how to prevent rapid contamination and prolong the life of your headphones.

Before you start cleaning, determine the degree of contamination:

• 🔊 Light pollution -- the sound is quieter, but there's no distortion.
• 🔇 Medium: You hear wheezing or mutedness. You need to clean the net deep.
• ❌ Strong: no sound, or severely distorted, corrosion possible, professional help required.

1.Preparation for cleaning: what will be needed and how to avoid damage

Before you clean your Xiaomi headphones of sulfur, prepare the tools and the workplace.

• 🧻 Soft lilac-free fabric (microfibra).
• 🧴 Isopropyl alcohol (70-90%) or special wipes for electronics.
• 🪥 Cotton swabs (better with a plastic rod, not a wooden one).
• 🪥 Toothbrush with soft bristles (new or clean).
• 💨 Canister with compressed air (optional, for hard-to-reach places).

Important: Never use water, acetone, gasoline or household detergents - they destroy the protective coating of the speakers. Also avoid metal objects (needles, pins) that can puncture the membrane.

⚠️ Note: If your headphones have active noise cancellation (ANC), Like the Xiaomi FlipBuds Pro, don't put alcohol in the microphone holes.

Work on a flat surface with good lighting. If you clean your wireless headphones, turn them off and take them out of the case. For wired models, unplug the plug from the device.

2. Dry cleaning: cotton swabs and toothbrush

This method is suitable for surface removal of sulfur and dust, and it is the safest and requires no liquids.

Cleaning steps:

1. Carefully remove large particles of sulfur from the headphones with a dry cotton swab. Move from center to edge without pressing.
2. To clean the speaker's mesh, use a toothbrush. Fish the sulfur with gentle circular movements. Don't rub too hard, the mesh may become deformed.
3. For hard-to-reach places (such as the gaps between the case and the mesh), use a cotton swab dipped in alcohol (slightly squeeze it so that it is almost dry).

If sulfur is stuck tightly to the net, don't try to scrape it. Better go to wet cleaning (see next section).

⚠️ Note: Do not use cotton wool, detached from the stick – its fibers can remain inside the headphones and further clog the speaker.

💡

To clean the microphone holes in ANC headphones, use a dry toothpick (not metal!) wrapped in a thin layer of cotton.

3. Wet cleaning: alcohol and special means

If dry cleaning didn't work, go to wet. The key here is not to overdo it with the liquid. Alcohol evaporates quickly and leaves no swelling, but excess alcohol can damage the internal components.

Instructions:

1. Moisten the cotton swab in isopropyl alcohol and squeeze it carefully so that it is barely wet.
2. Gently wipe the speaker grid, avoiding the alcohol going in. Move from center to edge.
3. To remove sulfur from the recesses, use a toothbrush soaked in alcohol. After processing, dry the headphones for 10-15 minutes.
4. If the sulfur has dried and is not removed, apply a drop of alcohol to the contaminated place, wait 1-2 minutes and repeat the cleaning.

For models with touch control (for example, Xiaomi AirDots 3 Pro), avoid getting alcohol on the touch panel – this can disrupt its operation.

💡

Isopropyl alcohol is the only safe liquid to clean headphones. Water, soap and household cleaners are prohibited!

4.Deep cleaning: how to remove sulfur from the speaker

If sulfur has penetrated deep into the speaker and the sound has become hoarse or disappears at low frequencies, a more thorough cleaning is required, a method suitable for wired headphones (for example, Mi Basic or Piston), since wireless models are more difficult to disassemble without risk of damage.

Step-by-step:

1. Remove the silicone embroideries (if any) and rinse them with warm water and soap. Dry them before installing them back.
2. If the speaker mesh is removable (as in some Hybrid models), gently tuck it in with a plastic card and remove it. Clean the mesh with alcohol.
3. For non-removable nets, use a cotton swab with alcohol, scrolling it slightly inside the hole. Don't push it, the membrane speaker is very thin!
4. If sulfur is not removed, apply 1-2 drops of alcohol to the net, wait 5 minutes and repeat the cleaning.

Critical: Never blow into the speaker with your mouth - saliva contains acids that corrode the contacts. Use a can of compressed air to dry or leave your headphones in a dry place for 1-2 hours.

5. Professional means and alternative methods

If home methods do not help, you can use specialized tools or equipment:

• 🧴 Wipes for cleaning electronics (for example, ScreenMom or WD-40 They're soaked in a safe solvent and they don't leave any divorces.
• 🔊 Ultrasonic Bath – suitable only for wired headphones without electronics in the case. Use distilled water and a short cycle (1-2 minutes).
• 💨 Vacuum cleaner with soft nozzle - will help remove dust from the case for wireless headphones.

For models with active noise cancellation (Xiaomi FlipBuds Pro, Buds 4), it is recommended to use special sets for cleaning headphones (for example, Sony Earbud Tips or Bose Cleaning Kit), These include brushes and wipes that are safe for ANC microphones.

If you are not sure about your skills, contact the Xiaomi service center. Headphone cleaning there costs from 500 to 1500 rubles (depending on the model), but guarantees the safety of the device.

6.Prevention: How to prevent the accumulation of sulfur

To clean Xiaomi headphones from sulfur less often, follow simple rules:

• 🧼 Wash or rub silicone bottles regularly (1 time per week).
• 🎧 Keep your headphones in a case – this protects against dust and mechanical damage.
• 🚫 Don’t share your headphones with others – it increases the risk of contamination.
• 🔄 Change the bulges every 3-6 months (they wear out and accumulate bacteria).
• 💧 Avoid using headphones while exercising unless they have sweat protection (IPX4 higher).

For models with touch control (AirDots 3, Buds 4), periodically wipe the touch panel with a dry wipe - sweat and fat from the skin worsen its sensitivity.

If you use headphones daily, do a preventive cleaning 1 time every 2 weeks, which will take 5-10 minutes, but will prolong the life of the device for years.

💡

Silicone embroideries are the main sulphur collector, and replacing them every six months reduces the risk of contamination of the speakers by 70%!
