How to carefully disassemble Xiaomi wireless headphones: instructions for all models

Xiaomi’s wireless headphones are some of the most popular accessories due to their value for money. However, over time, even the most reliable models (AirDots 3 Pro, Buds 4, FlipBuds Pro) can require disassembly to clean speakers, replace batteries or repair buttons. The main problem is that the manufacturer does not provide easy access to the insides, and improper actions often lead to damage to the plumes or loss of seals.

In this article, you will find step-by-step instructions for different models, a list of necessary tools and unique tips for disassembling without traces (for example, how to separate the adhesive base without damaging the body). We will also analyze the typical errors that turn simple repairs into expensive repairs. If your headphones stop charging, poorly hold charge or wheezing, this guide will help save you money at the service center.

What Xiaomi models can be disassembled independently

Not all Xiaomi wireless headphones are equally easy to disassemble. Here is a quick overview by generation:

• 🔧 Simple to disassemble: Redmi AirDots (1-2 Mi True Wireless Earbuds Basic 2 — Here the body is not glued much, and the fastenings are minimal.
• ⚠️ Medium difficulty: AirDots 3/3 Pro, Buds 4 — require heating to separate parts, risk of damage to the plume ~30%.
• 🚫 Complex (not recommended for beginners): FlipBuds Pro, Buds 4 Pro - sealed case with many latches and glue.

If your model is not specified, focus on the type of attachment: budget options usually have 2-3 latches + weak glue, flagships have ultrasonic welding + sealant.

Preparation: tools and security

Before disassembling, collect a minimum set of tools:

• 🔨 Plastic mediators (2-3 (a) - for separation of parts of the body without scratches.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic screwdriver. T3–T5 — for screws in some models (for example, AirDots 3 Pro).
• 🧴 Isopropyl alcohol 90%+ — glue-residue.
• 📦 Container for small parts – springs and washers are easily lost.

⚠️ Warning: Do not use metal blades – they leave microcracks on the plastic, which lead to loss of dust protection (IPX4/IP54). If the case is aluminum (like the FlipBuds Pro), the risk of deformation increases in the body. 3 once.

Also prepare the workplace:

• Cover the table with a soft cloth (such as a microfiber).
• Use a bright light source – many details are translucent.
• Remove the process on video - this will help to collect the headphone back, if you forgot the location of the parts.

Step-by-step: disassembly on the example of AirDots 3 Pro

This is one of the most common models, so let's go through it in detail. The process for other devices (Buds 4, Redmi AirDots 2) will be similar to the number of latches correction.

1. Step 1. Top cover separation Put the earpiece down with the speaker. Carefully insert the plastic mediator into the gap between the top and bottom of the body (on the side of the button). Smoothly drive the tool around the perimeter, slightly heating the body with a hairdryer (do not direct hot air to the speaker!) The glue will melt in 15-20 seconds. What if the cover does not detach?If the cover does not separate after heating, try to gently tap the mediator with a hammer (through a wooden gaske).
2. Step 2. Removal of the board After removing the lid, you will see: 🔋 Battery (stick to the body). 🎛️ Printed circuit board with chip BES2300 similar. 🔊 Dynamic (can be soldered or fixed with latches).

Unplug the speaker plume (it's brittle!) and gently tuck the board with the mediator. In AirDots 3 Pro, the board is attached to 4 T4 screws - don't lose them!

Step 3: Battery removal

The battery is glued to double-sided tape, put it in a wooden stick (not metal!) and wet the glue with alcohol. If the battery is swelling, don't puncture it! This can cause fire, and then you should contact the service.

Repeat the steps in reverse order to assemble, use a new B-7000 glue (ply thin!) or 3M 9448A double-sided tape for tightness.

💡

If the headphone doesn't turn on after assembly, check the contacts of the speaker plume with a multimeter, often the problem is microcracks on the board tracks that are not visible to the naked eye.

Features of disassembling other models

Each Xiaomi headphone series has unique nuances, and the table below shows the key differences:

For Buds 4 Pro and FlipBuds Pro, it is recommended to use special devices:

• 🛠️ Vacuum sucker – helps to separate the front panel without scratches.
• 🔧 Smartphone disassembly kit (e.g. iFixit Pro Tech Toolkit).

⚠️ Note: In models with active noise reduction (ANC) There's an extra microphone inside the body, and when you disassemble it's easy to damage it, and it's going to lose function. ANC recovery.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that turn repairs into disaster.

1. If you heat the earphone with a hairdryer for longer than 30 seconds or at temperatures above 90 ° C, the plastic deforms and the glue hardens. Use a thermometer for control or heat with short pulses (5 seconds of heating, 10 seconds of cooling).
2. Xiaomi plume damage is thinner than paper – you can’t pull or bend them. If the contact has gone, gently press it with plastic tweezers, not your fingers (fat from the skin worsens the contact).
3. Loss of dust protection after disassembly IP-To restore protection, use a sealant. LOCTITE 595 (applied around the perimeter of the housing before assembly).

💡

If the headphone does not hold a charge after assembly, check the polarity of the battery - in 70% of cases the problem is incorrect battery connection.

Cleaning and replacement of components

Most often, headphones are dismantled for:

1. Cleaning speaker Mesh speaker is clogged with earwax and dust. To clean: Use a soft brush (for example, for camera lenses); Moisten the cotton swab in alcohol solution (don't drip the liquid directly onto the speaker!). Blow compressed air (keyboard balloon) from 10 cm away.

Battery replacements

The average battery life in headphones is 2-3 years.

• 🔋 Fast discharge (less than 2 hours of work).
• 🔌 The headphone doesn't charge in the case.
• 🔥 Bloating of the body (seen by the divergent seams).

When disassembly is inappropriate

In some cases, self-repairing costs more than buying new headphones.

• 💸 The cost of spare parts exceeds 50% of the price of new headphones.
• 🔧 Replacement of the board (for example, the Bluetooth chip burned).
• 🔊 The speaker is damaged (in budget models, its price is comparable to the price of the device).
• 🔋 The body cracked in several places (it will be impossible to restore tightness).

For models older than 3 years (e.g. Redmi AirDots 1-gen), it is often cheaper to buy a new pair, except for collectible or rare versions (e.g. Mi AirDots Pro 2s with LDAC support).

💡

If the headphones are guaranteed, disassembly will cancel it, in which case it is better to contact the authorized Xiaomi service (even if the repair is paid).
