Disassembly Xiaomi AirDots: how to open the case, replace the speaker or battery without damage

Xiaomi AirDots headphones (including Pro, Pro 2 models, SE, 3) have become one of the most popular TWS-The headset is price-performance, but over time, even the headsets fail, with one earpiece shutting down, the sound disappearing, the battery running out, or the button breaking. In most cases, repairs are possible on their own – if you know how to properly disassemble the body without damaging the internal components.

This article is a step-by-step photo and video guide to help you gently open AirDots, replace your speaker, battery or microphone, and avoid common mistakes. We’ll break down the disassembly features for different versions of your headphones, tell you what tools you’ll need, and warn you of critical points that 90% of users overlook (for example, why you can’t use metal screwdrivers to lid).

Importantly, if your AirDots are still warranty, disassembly will deprive you of the right to free repairs. Otherwise, follow the instructions and you will save on the service center.

What tools will be needed to disassemble

Without the right tools, it is almost impossible to disassemble Xiaomi AirDots – the body is sealed and the internal parts are fragile.

• 🔧 Plastic mediator or spatula (preferably a phone repair kit) metal screwdrivers scratch the body and can damage the board.
• 🔥 A hair dryer or a thermo-air station (for softening the glue) will even work with a household hair dryer at maximum temperature.
• 🧲 Magnetic screwdriver (cross, size) PH00 or PH0). AirDots screws are tiny – they are easy to lose.
• 📏 Tweezers with thin ends (to extract plumes and contacts).
• 🧴 Isopropyl alcohol (90%+) — cleaner.
• 🔋 Multimeter (optional, to check the battery or speaker).

If you're planning to replace parts, buy parts in advance. For AirDots Pro 2, for example, you can:

• 🔊 Dynamics (impedance) 32 Ohm, diameter. 7-8 mm).
• 🔋 Battery (capacity) 55-60 MAC size 302530).
• 🎤 Microphone (capsule, with flexible legs).

Advice: if there is no hair dryer, you can use hot water (60-70°C) - put the headphone in it 10-15 But don't overdo it, because moisture can damage the board!

Preparation for disassembly: what to do before opening

Before you start, take a few critical steps:

1. Completely discharge the headphones. The battery can be energized if it is accidentally damaged.
2. Take a picture of the headphone from all sides, which will help you put it back together (especially for asymmetrical designs like the AirDots Pro).
3. Check the silicone mounts. They're easy to lose -- take them off and put them in a separate place.
4. Prepare your workplace. Use a white piece of paper or a light cloth, and you can see even the smallest details.

If you are looking at AirDots Pro 2 or AirDots 3, consider that they have additional protection against moisture (IPX4). This means that inside there may be a sealant - it must be carefully removed with alcohol so as not to damage the contacts.

⚠️ Warning: Don't use a microwave or oven to heat it! This will melt the plastic and damage the electronic components — 100°C, distance to the earphone — 5-10 centimeter.

Step-by-step: how to disassemble the case of Xiaomi AirDots

The disassembly process is slightly different depending on the model, but the overall scheme is the same. Consider the example of AirDots Pro 2 (for other versions, we will specify the nuances).

Step 1: Separation of the upper cover

1. Heat the body with a hair dryer during 1-2 minutes, evenly leading the jet of air along the seam.

2 Take a plastic pickup and gently pull the lid on the side where the button is located. Apply the force parallel to the body, not up, otherwise you will break the latches.

3. Use the mediator around the perimeter until the lid is removed. If the glue doesn't respond, repeat the heat.

Step 2: Fee extraction and dynamics

1. After removing the cover you will see:

- Battery (stick to the body).

- Board with chip and antenna (fixed with screws).

- Dynamic (soldered to the board or connected by a plume).

2. Unscrew 2 screws (in AirDots) SE They may not be there – the fee is kept on the latches).

3. Carefully tuck the board with a plastic spatula and unplug the speaker plume (if any). In AirDots Pro, the speaker is soldered off - it needs to be soldered off with a soldering iron on top of the speaker. 250-300°C.

Step 3: Replace the battery or speaker

For battery replacement:

1. Tap it with a plastic spatula (it is glued).

2. Clean the contacts with alcohol.

3. solder a new battery, observing polarity (+ and –).

To replace the speaker:

1. Unpold the old speaker (if soldered) or disconnect the plume.

2. Install a new one, making sure that it fits tightly to the body (otherwise there will be wheezing).

3.In AirDots 3, the speaker can be glued - use double-sided tape for fixation.

💡

If the speaker is quieter after you replace it, check the O-ring around it. In AirDots Pro 2, it is often lost in disassembly - without it, the bass disappears.

Common Mistakes in Disassembly and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that lead to the breakage of headphones.

• 🔥 If you hold the hair dryer too close, the plastic will deform, and the lid will not sit back — 5-10 centimeter.
• 🔧 Using metal tools. Stainless steel mediators scratch the body and can close contacts on the board.
• 💧 If you clean the glue with alcohol, don't put it on a board, just wet the cotton swab.
• 🔋 Battery soldering is not correct, overheating the battery causes it to swell.
• 🎧 Loss of the ossification ring speaker. Without it, the sound becomes "empty" - check for it before assembly.

⚠️ Attention: In AirDots Pro 2 and AirDots 3 antenna Wi-Fi/Bluetooth, If you cut it off, it'll break the connection!

Another common problem is when the button is broken after assembly, and this happens if:

• The plastic pusher button is set curved.
• There was glue or garbage under the button.
• The contacts on the board were oxidized (need to be cleaned with alcohol).

1. Battery polarity (plus/minus not confused?).

2. Integrity of plumes (especially in AirDots) SE).

3. Contacts charging "points" on the board - they could oxidize.-->

How to collect headphones back: tips for sealing

Assembly is as important as disassembly, and if you don't fix the parts properly, the headphones can:

• 🔊 Whisper or play quietly (bad fit speaker).
• 🔋 Quickly discharge (bad battery contact).
• 💦 Getting under moisture (unsealed housing).

Assembly order:

1. Set the speaker and board in place, fix the screws (if any).
2. Stick the battery with double-sided tape (do not use superglue!).
3. Apply a thin layer of sealant (for example, LOCTITE 577) to the edge of the shell before the lid is placed.
4. Press the lid tightly and fix with a strubbine or a heavy book on 10-15 minute.

For models with protection IPX4 (AirDots Pro 2, AirDots 3) after assembly check the tightness:

• Blow into the microphone hole - if you hear a whistle, the body is leaky.
• Place the headphone for 10 minutes in a bag of silica gel (will absorb moisture if it gets inside).

💡

If the headphone is heavier after assembly, it means that the glue or sealant has been put inside, wipe the body with alcohol and repeat the assembly.

What to do if the headphone does not work after disassembly

If after repair AirDots are not turned on, charged or connected to the phone, act according to the algorithm:

1.The earpiece is not switched on

Check it out.

• 🔋 Battery: Measure the voltage with a multimeter (should be) 3.7-4.2V).
• 🔌 Contact buttons: when pressed, there should be a click (if not, the button is not fully inserted).
• 🔌 Payment: inspect for burnt tracks or soldered parts.

2.The earphone is not charged

Possible causes:

• The charging contacts have been oxidized (clean with a lasticle or alcohol).
• The plume from the fee to the contacts (need to solder).
• The charge controller on the board is defective (a replacement board is required).

3.The headphone does not connect to the phone

Reset the settings:

1. Put the headphones in the case.
2. Press and hold the button on the case. 10-15 seconds until the indicator flashes red.
3. Take out your headphones and try to connect again.

⚠️ Note: If AirDots Pro 2 after repairs lost noise (ANC), Check: - Integrity of microphones (there are two - external and internal). - Setup in the Mi Home app (sometimes reset after disassembly).

Where to buy spare parts for Xiaomi AirDots

AirDots spare parts are sold on:

• 🛒 AliExpress is the biggest choice, but a long wait (2-4 Search for: “Xiaomi AirDots Pro 2 speaker" "AirDots 3 battery 60mAh" "TWS earbuds flex cable” (plugs)
