Disassembly of headphones Xiaomi Basic 2: step-by-step guide with photos and life hacks

Xiaomi Basic 2 is a popular model with a balance of price and quality, but even they are not immune to breakdowns. Most often, users experience a wire break at the plug, a failure of the microphone or contamination of the speakers. Disassembly of the device may be necessary to clean the membranes, solder contacts or replace damaged elements. However, the design of the headphones is far from the most repairable: the manufacturer did not provide removable mounts, and the body is sealed.

In this article, you'll find a step-by-step photo guide, a list of tools you need, and unique tips for disassembling without damaging plastic. We'll also tell you what mistakes lead to permanent headphone failure and how to avoid them. If you've never done electronics before, start by preparing your workplace, which will save you time and nerves.

Preparation for disassembly: tools and security measures

Before you start disassembling, make sure you have everything you need. Xiaomi Basic 2 has a fragile body, so a regular screwdriver or knife will not be enough.

• 🔧 Plastic mediators or shoulder blades (for careful separation of body parts).
• 🔥 Hair dryer or thermo-air station (for softening glue).
• 🧲 Magnetic screwdriver (cross-shaped, size) PH00).
• 🔍 loope USB-microscope (for working with small details).
• 🧴 Isopropyl alcohol (90%+) (clean-up).

Important: Don’t use metal tools to separate the body, they leave scratches and can damage the internal components, and if you don’t have plastic mediators on hand, you can replace them with guitar mediators or even a plastic card (but you have to double the accuracy).

⚠️ Warning: Do not heat the headphone case with an open flame (lighter, matches) that can melt plastic and damage speakers. The optimal temperature for softening the glue is 60-80°C.

Also prepare the workplace:

• 📦 Work on a clean, light surface (it is better to use a white sheet of paper – even small details are visible on it).
• 📸 Take pictures of each stage – this will help to properly collect the headphones back.
• 🧹 Keep a vacuum cleaner or brush on hand to remove dust and fine debris.

Xiaomi Basic Anatomy 2: What’s Inside and Where to Look for a Breakdown

Before disassembling, it is useful to understand how the headphones are built from the inside. Xiaomi Basic 2 consists of the following key components:

80 percent of the time, the problems are wired (especially at the point of entry of the plug or the headphone case) or contaminated speaker, less often the microphone or control board fails. If the headphones stop working completely, check them first on another device — maybe the problem is the connector of a smartphone or PC.

Fun fact: Xiaomi Basic 2 uses neodymium magnets in speakers that attract metallic sawdust and dust. If the sound is quieter or wheezing, it's likely that the membrane is full of debris, and cleaning can then restore the original sound quality.

Step-by-step disassembly of the headphone body

Now, the hard part is disassembly, and the Xiaomi Basic 2 has two halves glued together, and you can split them in two ways: thermal (heating the glue) or mechanical (neat squeezing), and we recommend combining both.

Heat the body with a hair dryer (60-80)°C) within 1-2 minutes|

Insert a plastic mediator into the gap between the halves of the body|

Carefully conduct the mediator around the perimeter, increasing the gap|

Do not use excessive force – plastic is fragile!-->

Step 1. Warm up the glue.

Turn on the dryer at minimum power and evenly warm up the headphone case for 1-2 minutes, holding the device at a distance of 5-10 cm The glue will become softer and the halves will be easier to separate. Do not overheat - plastic can deform!

Step 2: Separation of the body

Insert a plastic mediator into the gap between the halves of the body (start where the seam is visible). Carefully swipe the tool around the perimeter, gradually increasing the gap. If you feel resistance, warm up the problem area again with a hairdryer.

⚠️ Warning: Do not use a knife or screwdriver to separate the body! Metal leaves scratches and can damage the internal components. If the mediator does not help, try a toothpick or plastic shoulder blade.

Step 3: Extracting the insides

Once you split the case, you'll see a speaker soldered to the wire, and (in the mic model) a small board. Carefully remove the speaker, don't pull the wire, it can break away from soldered contacts. If the speaker is glued to the body, put a plastic blade on it.

Step 4: Inspection and diagnosis

Now we can start the repair:

• 🔊 If the problem is in the sound, check the speaker membrane for contamination or damage.
• 🎤 If the microphone is not working, check the contacts on the board (often they are oxidized).
• 🔌 If the headphones are not determined by the device - look for a wire break at the plug.

💡

If the speaker is contaminated, clean it with a soft brush dipped in isopropyl alcohol. Don't use cotton swabs, the villi can stay on the membrane and make the sound worse.

Typical breakdowns and how to fix them

So if you take the headphones apart, you might have one of the following problems, and we've collected some of the most common problems and ways to fix them.

1. Wire break at the plug or earphone

This is the most common failure. The wire in Xiaomi Basic 2 is thin and often rubbed in the bending places.

• 🔧 Re-silver the wire (if you have soldering iron and skills).
• 🔄 Shorten the wire (cut off the damaged area and connect the healthy parts).
• 🛠️ Strengthen the bending place with shrink tube or tape.

2.Display pollution (wheezing, quiet sound)

Dust and sweat enter the speaker through the grid, and over time, the sound becomes muffled or there is extraneous noise.

• 🧹 Cleaning of the membrane with alcohol and soft brush.
• 🔊 Purging with compressed air (a balloon for cleaning equipment).
• 🚫 Don’t use sharp objects – they can tear the membrane!

3. The microphone is not working.

Xiaomi Basic 2 with a microphone often oxidizes the contacts on the board.

• 🔬 Check the fee for corrosion or breakage of tracks.
• 🧴 Clean contacts with alcohol and cotton swab.
• 🔥 Re-silver the microphone if it's off the payroll.

4.Cracks in the body

Xiaomi Basic 2 plastic is quite fragile, and cracks can appear when disassembled carelessly.

• 💎 Sticking cracks with superglue (such as Loctite).
• 🔥 Strengthen the seam with epoxy resin (for reliability).
• 🔄 Replace the case (can be found on AliExpress or in service centers).

💡

If the sound is worse after repair, check the polarity when soldering the wires. Incorrect connection can lead to an imbalance of sound or a complete absence of bass.

How to collect headphones back: tips and life hacks

Assembly is as important as disassembly, and if you don't connect the halves of the body correctly, the headphones can creak, hold poorly, or even fall apart the first time you use them.

1. Check the location of the speaker - it should fit tightly to the body, without distortions.
2. Lay the wire neatly, without any sharp curves, and you can add a drop of glue to the exit of the case to fix it.
3. Grease the glue seam with a thin layer of cyanoacrylate glue (for example, "Moment"). Don't overdo it - excess glue can get inside.
4. Fix the body with a clamp or rod for 10-15 minutes until the glue is grasped.

If the headphones creak when you're moving after assembly, it means the speaker or the wire is preventing the halves of the body from connecting tightly, take them apart again and check if there's nothing sandwiched between the parts.

Lifehack: to get glue caught faster, you can warm the body a little with a hairdryer (40-50)°C) after bonding, but do not overheat - plastic may deform!

What NOT to do: Top-5 rookie-buyer

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi Basic 2.We have collected the most dangerous blunders that can turn a repair into a final breakdown.

• 🔥 Hydrogen overheating (>100°C) - plastic melts, speaker deforms.
• 🔪 Use of metal tools – scratches, chips, damage to contacts.
• 💦 Getting moisture on the board or speaker - corrosion, short circuit.
• 🔌 Strong pulling for the wire - break of contacts at the base.
• 🧲 The use of superglue inside the case - a pair of glue can damage the speaker membrane.

⚠️ Warning: If you accidentally tore the speaker membrane, don't try to tape it! The sound will get distorted and the headphones will have to be thrown away. In this case, it's cheaper to buy a new Xiaomi Basic 2 than try to repair it.

Another common mistake is the wrong soldering of the wires («+» and "-"), the sound will be quiet or disappear. Always check the connection circuit before soldering!

Alternative repair methods without complete disassembly

You don't always have to take your headphones down to the cog, and in some cases, you can do it with minimally invasive methods that save time and reduce the risk of damage.

1. Wire repair without disassembly of the body

If the wire broke at the plug, it can be shortened without opening the headphones:

1. Cut off the damaged area (leave 10-15 cm from the plug).
2. Clean the wires and solder a new connector (or use the old one if it's intact).
3. Insulate the soldering site with a shrink tube.

Cleaning dynamics without disassembly

If the sound is quieter, but to disassemble the headphones is scary, try:

• 🎵 Blow the speaker with compressed air (a canister for cleaning the keyboard).
• 🔊 Knock on the body with light movements - sometimes the dust falls out on its own.
• 🧴 Dump 1-2 drops of alcohol through the net and let evaporate (dissolves pollution).

Removal of squeak in the body

If the headphones creak when moving, but do not want to disassemble them, try:

• 💧 Bury silicone lubricant in the gap between the halves of the body.
• 🔥 A little warm the body with a hairdryer - sometimes it helps the glue "fresh off».

These methods do not give a 100% guarantee, but in half cases they help to avoid complete disassembly.
