Disassembly of headphones Xiaomi Earphones 2 Basic: instructions with photos and repair tips

Xiaomi Earphones 2 Basic is a popular price-balanced model, but even these are not immune to breakdowns. Most often, users face problems with wires, microphones or one of the speakers. Instead of buying new headphones, many prefer to repair old ones, but to do this, you need to take them apart correctly.

In this article, you will find step-by-step disassembly instructions tailored to the design of the Earphones 2 Basic, a list of tools you need, and cautions to avoid typical errors. We will also look at which parts can be replaced yourself, and in which cases it is better to consult a specialist.

Important: disassembling the headphones will void the Xiaomi warranty if it is still valid. If the device is warranty, contact the service center first.

Preparation for disassembly: tools and precautions

Before you get started, make sure you have everything you need. The Xiaomi Earphones 2 Basic doesn’t need professional tools to disassemble, but choosing the wrong screwdriver or knife can damage the case or wires.

Here's what you're gonna need:

• ✅ Flat screwdriver with a thin sting (1-1.5 mm) - to separate the halves of the body, a screwdriver for repairing phones or watches is suitable.
• ✅ Plastic mediator or guitar mediator – to gently lid without scratching the plastic.
• ✅ Tweezers with thin ends – for working with small details inside.
• ✅ Insulation or shrink tube - if you plan to repair wires.
• ✅ Dryer or soldering iron (up to 30 W) - if you need to drink the contacts.
• ✅ Lump or magnifying glass - for inspection of small elements (resistors, contacts).

Also, prepare your workspace: a clean desk with good lighting, preferably with a white substrate (so you don't lose any fine details). If you're taking your headphones apart for the first time, take a picture of each stage, which will help you put them back together properly.

⚠️ Warning: Do not use metal knives or screwdrivers with a wide sting - they can damage the latches of the case or cut through wires. Plastic tools are safer, but require more effort.

Xiaomi Earphones 2 Basic: What’s Inside?

Before disassembling it is useful to understand how these headphones are arranged. Earphones 2 Basic have a classic design with:

• 🔊 Dynamic 10 mm diameter (in each cup).
• 🎤 Microphone on the wire (control module with button).
• 🔌 3.5 mm connector (straight or L-shaped, depending on version).
• 🔗 Wires with a multi-core structure (often torn at the base).

Inside each cup you will find:

• Printed circuit board with contacts for the speaker.
• Soundproofing gasket (may be glued).
• Latches or glue that lock the body.

The most vulnerable areas:

1. The wire at the base of the cup is often rubbed.
2. The microphone contacts are oxidized or soldered off.
3. The soldered connections on the board - can move away from vibration.

💡

If the headphones start to "wheez" or one channel is quieter, the problem is most often the dynamics or contact board. Before disassembling, try to clean the 3.5 mm connector with alcohol - sometimes this solves the problem.

Step-by-step: how to disassemble a cup of headphones

So, to start with, the hardest part is disassembling one of the cups. In Xiaomi Earphones 2 Basic, the body is not glued very tightly, but the latches are tightly held. Be careful not to break the plastic.

Step 1: Unplug the cup from the wire

If there is a problem with the wire (for example, a cliff at the base), you can try to repair it without completely disassembling.

1. Find the place where the wire enters the cup case.
2. Carefully cut the external insulation by 1-1.5 cm (without touching the inner veins!).
3. If you see a cliff, clean and solder the wires, then isolate them with a thermal shrinkage.

Step 2: Separate the body

If you need to get to the speaker or board:

1. Take a plastic mediator and insert it into the gap between the halves of the case (start on the side opposite the wire).
2. Carefully lead the mediator in a circle until you hear a click - this means that the first latch has disconnected.
3. Repeat the other latches (usually 3-4).
4. If the body does not respond, slightly heat it with a hair dryer (not higher than 60).°C. This will soften the glue.

Step 3: Remove the insides

After you have separated the body, you will see:

• Printed circuit board with soldered speaker.
• Wires going to the connector (usually red and green - left / right channels, copper - general).
• Soundproofing gasket (can be glued to the speaker).

Important: If you're disassembling your headphones because of a quiet sound or wheezing, check the speaker for damage to the membrane, sometimes just clean it with a soft brush.

⚠️ Attention: Don't pull the wires from the board to the connector, they're very thin and they come off the solder easily. If you need to move the board, grab the edges.

Disassembly of the control module with a microphone

The microphone and the response/control button is the second most common cause of breakdown, and most often, the button fails or the microphone stops transmitting voice, and it's harder to disassemble than the cup, but it's possible.

Step 1: Remove the rubber plug

There's a silicone or rubber plug on the module that covers the button, and you can gently put it in a thin screwdriver and take it off, and underneath it you'll see a plastic button and a microphone.

Step 2: Open the module body

The body of the control module is usually glued together to separate it:

1. Find the seam on the body (usually it is less noticeable from the side).
2. Insert the mediator in the seam and carefully dilute the halves.
3. If you don’t, heat it with a hair dryer (don’t direct hot air to the microphone!).

Step 3: Check the fee

Inside you'll find:

• 🔘 The button (often soldered to the board).
• 🎤 Microphone (small black cylinder).
• 🔌 Contacts for connecting to wires.

Typical problems:

• 🛠️ Oxidation of contacts - cleaned with alcohol and cotton swab.
• 🔧 The microphone is broken, you need to sell it back.
• 💥 Broken button – requires replacement (you can take the donor from other headphones).

Wire repair: soldering and insulation

The wire break is the most common malfunction of Xiaomi Earphones 2 Basic.

• 📍 At the base of the cup.
• 📍 The connector has 3.5 mm.
• 📍 At the place of splitting (Y-shaped connector).

How do you find the cliff?

Call the wire with a multimeter in circuit check mode. If there's no signal, there's a break between the measurement points. You can also bend the wire in different places, if you bending the sound, you see the break here.

Step-by-step repairs:

1. Carefully cut the insulation by 1-2 cm at the cliff site.
2. Clean the internal veins (usually 3-4: left channel, right channel, general and microphone).
3. So, make sure you have a green, red, and green, and so on.
4. Seal the place with a soldering iron (temperature not higher than 250)°C).
5. Put a heat shrink tube or wrap with tape.

If the cliff is 3.5mm, it's easier to replace the entire connector, and new connectors are sold on radio market sites (e.g., the L-shaped 3.5mm jack) and cost pennies.

⚠️ Warning: When soldering, do not overheat the wires - they may melt or lose flexibility. Use a solder with a roanifoil and a soldering iron with a power of no more than 30 watts.

💡

If after repairing the wire the sound became quieter or there were interference, check the quality of soldering - perhaps the contacts are not warmed up enough or there is a circuit between the veins.

Cleaning speakers and contacts: how to return clear sound

Over time, the Xiaomi Earphones 2 Basic speakers accumulate dust, which worsens the sound, and also oxidize the contacts on the board, which leads to wheezing or loss of sound in one of the headphones.

Cleaning dynamics:

1. Remove the soundproofing mesh (it can be glued or fixed on the latches).
2. With a soft brush (for example, for drawing) remove dust from the speaker membrane.
3. If there are spots - gently wipe with a cotton swab dipped in alcohol (do not press the membrane!).

Cleaning contacts on the board:

1. Check the charge for oxidation (green or white coating).
2. Wipe the contacts with a cotton swab soaked in alcohol or a special liquid to clean the contacts.
3. If the oxidation is strong, gently scrape with a wooden toothpick.

After cleaning, allow the parts to dry (10-15 minutes) before assembly.

If the sound doesn't recover:

• Check the integrity of the speaker membrane (if torn - replacement is required).
• Make sure the wires are tightly soldered to the board.
• Call the multimeter circuit from the connector to the speaker.

Assembly of headphones after repair

Putting Xiaomi Earphones 2 Basic back together is harder than disassembling – you need to make sure all parts are in place and the case is tightly closed.

Assembly order:

1. Lay the wire gently, without overburdening.
2. Place the board with the speaker in the lower part of the case.
3. Make sure the soundproofing pad is in place (it affects the sound!).
4. Combine the halves of the body and press carefully until the latches click.
5. If the case does not close, check whether the wire or board interferes.

Post-assembly check:

• 🔊 Connect the headphones to the device and check the sound in both channels.
• 🎤 Test the microphone (record the voice message).
• 🔘 Make sure the control button is working (pause, answer the call).

If the sound gets worse after assembly, you may have forgotten to install the soundproofing pad or you may have misfolded the wire. Take the headphones apart again and check.

⚠️ Warning: If the case does not close tightly, do not use glue (such as superglue or moment) - it can damage the plastic or penetrate inside).
