Disassembly of Xiaomi headphones: from mounts to speakers - a complete guide with nuances

Xiaomi headphones are some of the most popular accessories thanks to the price-quality ratio, but even they are not immune to breakdowns. TWS-Many users face these problems, and you can disassemble headphones yourself, but the process requires care: improper handling of adhesive seams or flexible plumes often leads to irreversible damage.

In this article, you will find step-by-step instructions for different models, from the budget Redmi AirDots to the premium Xiaomi FlipBuds Pro, as well as unique mounting schemes that the manufacturer does not disclose in the official documentation. We will tell you what tools are really needed (and which can be replaced with improvised tools), how to avoid typical errors when opening the case, and what to do if the headphones stop working after disassembly.

What Xiaomi models can be disassembled at home

Not all Xiaomi headphones are equally repairable. For example, ultra-compact models (like the Mi True Wireless Earbuds Basic 2) often assemble on screwless latches, but their plastic mounts are fragile and break when unsavoryly opened. The table below is an assessment of the complexity of disassembly for popular series:

If your model is not listed in the table, pay attention to the material of the case:

• 🔹 Matt plastic (such as Redmi Buds 3) is usually glued together and will require isopropyl alcohol or hair dryer to disassemble.
• 🔹 Plastics (like the Mi Air 2) SE) They are often held on latches, but they are difficult to detect without experience.
• 🔹 Metal inserts (premium models) almost always have screws under rubber plugs.

⚠️ Attention: Headphones with certification IPX4/IPX5 (Moisture protection often has an additional sealant at the seams. its removal without a special tool (plastic mediator) can damage the seals!

Disassembly tools: what you need and what can be replaced

Professional craftsmen use microelectronics kits, but at home many tools can be replaced with improvised tools, the main rule being: do not use metal objects (knives, screwdrivers) to open plastic cases - they leave scratches and chips.

Minimum set:

• 🔧 Plastic mediator (or guitar mediator) – to separate glued parts.
• 🔧 Screwdriver. T3/T4 (for screws in FlipBuds Pro or Air 2 Pro).
• 🔧 Tweezers (better with curved ends) - for extracting plumes.
• 🔧 Hair dryer (or burner at minimum power) - to soften glue.
• 🔧 Scotch or tape to mark the location of parts.

If there are no specialized tools:

• 💡 Instead of the mediator, a plastic card will suit (close the corner for convenience).
• 💡 Screws. T3/T4 You can twist a toothpick with a melted end (heat with a lighter and shape a screwdriver).
• 💡 To heat the glue, use an iron through the foil (temperature not higher than 60).°C).

Before starting work, prepare the workplace:

Remove carpets and fabrics (static electricity damages boards)|

Close windows (dust can get to contacts)|

Put white paper (small details are visible)|

Take photos of headphones from all sides (for assembly)-->

⚠️ Attention: If you disassemble wireless headphones with touch control (for example, Xiaomi Air 2 Pro), do not touch the touch pad with your bare hands - fat marks will violate its sensitivity.

Step-by-step disassembly of wired headphones Xiaomi (on the example of Mi In-Ear)

The Mi In-Ear Headphones Pro HD, Mi Hybrids are easier to understand than wireless ones, but the main difficulty is the thin wires that often break off from contacts when handled carelessly.

Step 1: Removal of silicone embushures

• 🎧 Carefully pull the bottle from the body, it should be removed effortlessly.
• 🎧 There may be a metal mesh (dust protection) under the mount – don’t lose it!

Step 2: Separation of the body

• 🔍 Look at the seam between the front and back of the body, and there's usually a little gap there, and you can put a mediator in it.
• 🔍 Turn the mediator around until you hear a click (this latch has opened).

Step 3: Extract the speaker

• 🔊 The speaker is attached to the body with two wires (red and black), carefully solder them with a soldering iron (temperature not higher than 250).°C).
• 🔊 If there is no soldering iron, you can snack on the wires with cutters, but then you will have to connect them later with a twist.

Inside you'll see:

• 🔹 Dynamics (usually diameter) 10-14 mm).
• 🔹 Microphone (in models with remote control).
• 🔹 Low frequency filter (small black box).

Disassembly TWS-Xiaomi headphones (on the example of Redmi AirDots 3)

Wireless headphones are more difficult to disassemble because of the compactness and the presence of a battery that is often glued to the board, the main danger is to damage the Bluetooth antenna (the thin copper track on the board) or the microphone plume.

Step 1. Heat the body.

• 🔥 Heat the back cover of the headphone with a hair dryer during 20-30 seconds (temperature) 50-60°C. This will soften the glue.
• 🔥 Don’t overheat – plastic can be deformed!

Step 2: Separation of the cover

• 🛠️ Insert the mediator in the gap between the front and back of the body.
• 🛠️ Rotate carefully until the lid is removed. If you feel resistance, heat it up again.

Step 3: Extracting the fee

• 🔧 The board is attached to the body with two screws T3 (AirDots 3) or Latches (in Mi True Wireless 2).
• 🔧 Disconnect the microphone plume (it goes to the top of the headphone).
• 🔧 The battery can be glued - put it with a plastic shovel.

Inside you'll find:

• 🔹 Board with Bluetooth chip (usually Qualcomm) QCC3020/3040).
• 🔹 Battery (capacity) 40-60 mic).
• 🔹 Dynamics (diameter) 6-8 mm).
• 🔹 Antenna (thin copper stripe).

💡

If the headphone doesn't turn on after disassembling, check the contacts of the battery - they often oxidize. Wipe them with a cotton swab with alcohol.

Typical problems after disassembly and how to fix them

Even if you carefully disassemble the headphones, after assembly, you can have problems.

If after assembly, the headphones squeak or crack, most likely, the speaker is installed incorrectly:

• 🔊 Check if it is close to the body (there should be no gaps).
• 🔊 Make sure the wires do not touch the membrane (this causes interference).

⚠️ Note: If after the dismantling of Xiaomi FlipBuds Pro stopped working ANC (active noise reduction, check the microphone on the leg of the headphone - its plume often departs with a careless opening.

How to Clean the Speaker and Microphone Without Disassembly

You don't always have to take your headphones apart to get them back to their sound, so if it's dust or earwax, try these methods:

For the speaker:

• 🎵 Use a toothpick with cotton wool (soaked in alcohol) to clean the mesh.
• 🎵 Blow the speaker with compressed air (a canister for cleaning equipment).
• 🎵 Don’t use wet wipes – they leave fibers behind.

For the microphone:

• 🎤 Carefully tap on the headphone case - sometimes the dust falls out on its own.
• 🎤 Use a soft brush (for example, for painting).
• 🎤 If the microphone is completely silenced, try blowing it with your mouth (not too much!).

2. 2️⃣ Dry the dryer in cold mode (at least 2 hours).
3. 3️⃣ Check the sound – if there are wheezing, repeat drying.

💡

If the sound gets worse after cleaning, it means that the moisture has got on the speaker membrane, in which case you need to take apart the earphone and dry it in rice or silica gel. 12-24 hour.
