How to clean the headphone in the Xiaomi phone: from dust, dirt and moisture

Clogged connectors or headphones in Xiaomi smartphones are a problem that every second user faces: Dust, pocket pile, sweat or occasional splashes of liquid gradually worsen the sound quality: wheezing, bass disappears, or one ear stops working at all. But before you carry the phone to the service center, try cleaning the earphone yourself.

In this article, we will discuss 5 proven cleaning methods, from the simplest (with toothpicking) to advanced (ultrasonic bath for complex contaminants). Particular attention will be paid to models with a 3.5 mm connector (Redmi Note 10 Pro, POCO X3 Pro) and wireless headphones (Xiaomi AirDots, Buds 4 Pro).

Signs of clogging headphones in the Xiaomi phone

Before you start cleaning, make sure that the problem is the contamination, not the software failure or damage to the cable.

• 🔊 Muffled sound – basses disappear, high frequencies become quieter.
• 🎵 Wheezing or crackling when playing music, especially at high volume.
• 👂 One ear is not working or the sound is only coming from one side.
• 🔌 Headphones are defined, but the sound is interrupted (a typical problem for Redmi). 9A and POCO M3).
• 💧 Moisture under the mesh speaker (seen in bright light).

If the sound is completely lost, first check the settings: go to Settings → Sound → Sound quality and turn off the Adaptive Sound function – sometimes it conflicts with the headphones. Also try to connect other headphones: if the problem persists, the jack in the phone is clogged, not the headphones themselves.

⚠️ Warning: If the sound is not restored after cleaning, do not try to stick metal objects (needles, paper clips) into the connector.

Method 1: Dry cleaning with a toothpick or cotton swab

The safest method for 3.5 mm jack and mesh speaker in wired headphones. Suitable for Xiaomi models with classic audio jack: Redmi Note 8 Pro, Mi A3, POCO F1.

This method removes up to 80% of the dust, but it can't handle stuck dirt or oxidation of contacts. If the sound doesn't improve after cleaning, move on to the next method.

Method 2: Compressed air cleaning (a balloon or vacuum cleaner)

How to clean:

1. Keep the canister vertically (so that no liquid leaks).
2. Direct the air stream into the connector with short pulses (2-3 seconds).
3. For headphone speakers, use a minimum distance (5-7 cm) to avoid damaging the membrane.
4. After processing, turn the phone downwards and leicht tap on the case to make the dirt fall out.

⚠️ Warning: Never use a hair dryer instead of compressed air! hot stream can melt plastic jack parts or damage the microphone in headphones.

Method 3: Ultrasonic Bath for Complex Contaminants

If Xiaomi’s headphones have been in a dusty place for a long time or have been exposed to liquid, conventional methods may not help, in which case an ultrasonic bath will save you – it removes dirt at the molecular level without damaging the electronics.

What do you need?

• 🛁 Ultrasonic bath (you can buy for 1,500-3000) ₽).
• 💧 Distilled water or isopropyl alcohol (90%).
• ⏱ Timer.

Instructions:

1. Remove silicone earbuds from headphones (if any).
2. Pour alcohol (not water!) into the bath for 2-3 cm.
3. Place the headphones in the bathtub basket with speakers up.
4. Set the time - 3-5 minutes at a temperature of 30-40 ° C.
5. After processing, dry the headphones for 24 hours in a dry place.

This method is suitable for Xiaomi AirDots Pro, Buds 4 and other models with waterproof IPX4 and higher. For wired headphones with fabric wool, ultrasound can not be used - it will damage the insulation.

Method 4: Clean Type-C connector (for models without 3.5 mm)

Xiaomi smartphones without audio jack (Redmi K50, Xiaomi 12T, POCO F4) use Type-C to connect headphones. its cleaning requires special care, as the contacts are thinner and denser.

Tools:

• 🧲 Plastic shoulder blade (for SIM-map).
• 🔍 Lupa (for accuracy).
• 🧴 Alcohol napkins.

How to clean:

1. Turn off the phone and remove the cable.
2. Slightly shovel the upper part of the connector - there accumulates the most dust.
3. Wipe the contacts with a napkin soaked in alcohol, moving along the connector (not across!).
4. Blow the connector with compressed air.

If the headphones are still not recognized after cleaning, check the settings → Settings → Additional → Developer → USB debugging. Sometimes the failure occurs due to a conflict of data transfer protocols.

💡

Before cleaning Type-C, check if the contacts are bent. If so, don't try to straighten them yourself, it can lead to short circuits.

Method 5: Software Diagnostics Before Cleaning

Before you take apart your headphones or pick up the jack, make sure it's not the software that's the problem. Xiaomi smartphones have built-in audio checker tools.

How to check:

1. Open the Phone app and dial ##4636##.
2. Select Phone Information → Check the speaker.
3. If the sound is only in one headphone, the problem is in the hardware.

Also try to reset the sound settings:

Settings → Sound → Additional → Resetting sound settings

If the problem persists after reset, proceed with physical cleaning.

What not to do when cleaning headphones Xiaomi

Some folk methods can permanently damage headphones or audio jacks.

• 🚫 Blow the connector with your mouth – saliva contains acids that oxidize the contacts.
• 🚫 Use needles or pins – they scratch the contact coating.
• 🚫 Pour alcohol or water directly into the speaker – the liquid stays inside and spoils the membrane.
• 🚫 Cleaning headphones in the on state - the risk of short circuit.
• 🚫 Dry with a hair dryer or on a battery - overheating deforms the plastic.

If you accidentally fill your headphones with liquid, don't turn them on for at least 48 hours. Put them in a silica gel bag (from a shoe box) - it will absorb moisture.

💡

The most common reason for headphones to break after cleaning is mechanical damage to the membrane. Never press the speaker grid or use abrasive materials.
