Why Xiaomi AirDots Headphone Doesn’t Work – and How to Fix It in 10 Minutes

You took out the Xiaomi AirDots case, turned on the music, and suddenly you found that one earbud doesn't make a sound, doesn't connect or doesn't respond to any pressing, and this is a familiar situation for many owners of this series of wireless headphones, and the reasons can vary from a trivial battery discharge to hardware breakdowns, but in 80 percent of cases, you can solve the problem yourself without going to the service center.

In this article, we’ll look at all the possible reasons why a single Xiaomi AirDots headphone (including Redmi AirDots, AirDots Pro, Air 2/3, Buds, etc.) might stop working, and give you step-by-step instructions for fixing them. From simple actions like resetting to disassembling the case, you’ll find a solution for even the most difficult cases, and if the headphone does die, we’ll show you how to save on repairs or replacements.

Before you start the repair, answer one question:

1. Checking for obvious causes: battery, connection, dirt

Start with the simplest. Often the problem is the little things that users don't pay attention to. Here are three key things to check first:

• 🔋 Case charge and headphone charge. Even if the indicator on the case is green, it doesn't guarantee that both earphones are charged. Take them out and see if one of them doesn't flash white when it's removed, it's discharged. Put it back and wait 10 to 15 minutes.
• 🔗 Connect to the device. Sometimes the headphones connect to the phone separately (for example, only the right one). → Bluetooth and check if both headphones are displayed as Mi True Wireless or Redmi. AirDots_L/R.
• 🧹 Contact contamination or speaker: Dust, earwax or moisture can block sound. Check the speaker grille and charging contacts on the headphone — if you see dirt, clean them carefully (more on this in the next section).

If you've had this manipulation, you don't have to use your earphone, but first, you have to give me an important warning.

⚠️ Don't try to blow out the earphone speaker with your mouth or compressor. The high flow of air can damage the membrane, and it'll cost more to repair than buying new AirDots.

Also pay attention to the headphone indication:

2. Headphone cleaners: how to remove dirt without damage

Clogging of the speaker or contacts is one of the most common reasons why Xiaomi AirDots stops playing sound, especially if you wear headphones while exercising or outdoors. Here's how to clean them correctly:

• 🧼 External cleaning. Take a cotton swab, moisten it in isopropyl alcohol (60%+) Or hydrogen peroxide, and gently wipe the speaker grille and charging contacts!
• 💨 Dust removal: Use a soft brush (for example, for makeup) or a vacuum cleaner with minimum power at a distance of 5 cm from the earphone.
• 🚫 What not to do: Wash your headphones with water (even if they have protection) IPX4). Use sharp objects (needles, toothpicks) to clean the speaker, dry with a hair dryer or put on the battery.

If you've had a sound after cleaning, but it's quieter or wheezing, it's likely that the speaker membrane is damaged, and then the replacement will help.

💡

To prevent contamination, keep your headphones in a case and wipe them once a week with a dry wipe, which will prolong their life by 30-50%.

If the cleaning didn’t help, move on to resetting the settings.

3.Reset Xiaomi AirDots headphones to factory settings

Reset (or hard reset) is the universal solution for most software failures, and it will return the headphones to factory status and reconnect them as a new device. Xiaomi/Redmi AirDots, including Pro, Air 2, Air 3, Buds.

Here's a step-by-step algorithm:

1. Put both headphones in the case and close the lid.
2. Pull them out and hold the buttons on both headphones for 15-20 seconds (until the indicators start flashing red and white alternately).
3. Release the buttons – the headphones will reset (it will take about 30 seconds).
4. After resetting, the indicators will start flashing white – this means that the headphones are ready to pair.
5. Go to Settings → Bluetooth on your phone, find Mi True Wireless (or similar name) and connect.

If after resetting one headphone still does not connect, try to connect it separately:

• 📱 Get only a problem earpiece from the case.
• 🔍 Hold the button on it for 5-7 seconds until the indicator starts flashing white.
• 🔗 Connect to it via Bluetooth as a new device.

⚠️ Attention! On Xiaomi AirDots 3 Pro and Buds 4, the reset is different: you press the headphone button three times quickly, then hold it for 10 seconds!

If the reset didn't work, the problem could be in the firmware or the hardware. Read on.

4. Headphone firmware update (if available)

Xiaomi periodically releases firmware updates for its wireless headphones, fixing bugs with connection and sound. However, not all models support updating through the application - for example, the budget Redmi AirDots are updated only through the service center.

If your model supports you OTA-Updates (for example, AirDots) 3 Pro, Buds 3/4), follow this instruction:

• 📲 Install the official Mi Home or Xiaomi Wear app (depending on the model).

Important nuances:

5. Checking hardware faults: what can be repaired yourself

If the software methods didn't work, the problem is probably the hardware, and let's look at the most common breakdowns and how to fix them.

Damage to charging contacts

Over time, the contacts on the headphone or in the case become oxidized or worn out, which leads to the fact that one earphone does not charge and, as a result, does not work.

• 🔍 Check the contacts on the headphone and in the case – they should be clean and shiny (not black or green from oxidation).
• 📊 Check if the indicator on the case is on when you connect the charger. If not, the problem is in the case, not the headphone.

If the contacts are oxidized, clean them with a blower or alcohol, if they are physically damaged (for example, bent), you can straighten them neatly with a needle, but this is a temporary solution - soon the problem will return.

Breakdown of speaker or microphone

If the earphone is plugged in but not producing sound or sound distorted (wheezing, crackling), it's likely that the speaker membrane is damaged.

• 💦 Moisture intake (even if the headphones are protected) IPX4, It does not save from prolonged exposure to water).
• 🎵 Too loud (membrane breaks from vibrations).
• 🤏 Physical pressure (for example, if the earpiece is stepped on).

In this case, repair is possible only in the service - the speaker is sealed on the board, and it is impossible to replace it yourself without a soldering iron and experience. ₽ (model-wise).

Disassembly of the headphone: when justified

If you're sure the problem is with the contacts, the battery or the button, you can try disassembling the earphone yourself.

• ⚠️ The guarantee will be lost (if it is still valid).
• 🔧 You will need plastic mediators, tweezers and hair dryer (to soften the glue).
• 💥 The risk of damaging the board or speaker during disassembly is very high.

If you do, here is a brief instruction:

1. Heat the headphone case with a hairdryer (60–70°C) for 1-2 minutes to soften the glue.
2. Carefully apply the lid with a plastic mediator (not a knife!).
3. Disconnect the battery (it is glued) and check the integrity of the contacts.
4. If you see damaged tracks on the board - they can be restored with conductive glue.

⚠️ Attention! Xiaomi AirDots headphones use a lithium battery. Don't puncture it or heat it above 80.°C – This can lead to a fire!

If you're not sure about your abilities, you should put the headphones in the service. Average cost of diagnosis: 300-500 ₽.

6.If nothing worked: Buying a new headphone or repairing

If all of the above methods don’t work, you have three options:

1. Buy a new headphone (left or right) separately. Cost: 500-1200 ₽ depending on the model: 🛒 Xiaomi official service (6 months warranty). 🌍 AliExpress (cheap, but the risk of running into a fake). 🔧 Local electronics repair services (sometimes sold used parts).
