Xiaomi’s modern acoustics are renowned for their minimalist design and compact form factor, often achieved through the use of hidden screws and adhesives. Xiaomi Earphones 2, whether wired or wireless, is no exception and requires a special approach when dismantled. Owners often face the need to replace a power supply or restore the speaker when the device stops charging or sounding.
The process of opening the case carries the risk of damaging plastic latches or tearing the plume, so it is crucial to prepare a specialized tool before starting work. Thin plastic blades and a quality hair dryer are not just desirable tools, but prerequisites for a successful and accurate disassembly. In this article, we will look at each step in detail so that you can safely reach the insides of the device.
It should be noted immediately that any interference with the design of the gadget automatically deprives you of warranty service. If the problem is a software failure, you may want to try resetting via the Bluetooth menu or holding the touch zones first. However, if the device physically fails, you have no choice but to proceed with a tidy dismantling.
Preparation of the workplace and the necessary tool
The high-quality disassembly of any electronics begins long before you touch the first screw. You need to organize a clean, well-lit space where fine details are not lost. The light should fall evenly without creating glare on the glossy surfaces of the headphones so that you can see the microscopic gaps.
The basic toolkit should include thin plastic mediators or special blades for opening, because metal tools can split the body, and the indispensable tool will be a hair dryer to soften the adhesive layer and a thin tweezer to extract small components. Remember the suction cup if the model has a smooth outer surface.
⚠️ Note: Using metal blades or knives instead of plastic shoulder blades is 99% likely to cause deep scratches and chips on the ends of the body that cannot be eliminated.
To collect screws and small parts, prepare a magnetic mat or a few small containers, which will help to avoid the situation when you have unnecessary parts after assembly, the best way to capture the procedure is visually, taking photos at each stage.
Algorithm of safe opening of the headphone case
The first step in the process of disassembling the Xiaomi Earphones 2 is to heat the perimeter of the halves connection of the body.The adhesive composition used by the manufacturer is thermoplastic and softens at a temperature of about 60-70 degrees Celsius.Great the body evenly in a circle, constantly moving the hair dryer so as not to overheat the battery or speaker matrix.
Once the body is sufficiently warmed, insert a thin plastic blade into the barely noticeable joint between the top and bottom, move the tool smoothly, without sharp jerks, gradually passing along the entire perimeter, and you will hear the characteristic click of the snapping internal latches.
☑️ Checking readiness for autopsy
If the halves of the body don't diverge, don't use force. Repeat the heating procedure. Often the glue freezes unevenly, and some areas require longer exposure to temperature. Patience in this process is a key success factor.
Dismantling the battery and replacing the battery
Once the lid is successfully removed, you will see the internal layout of the device. In Xiaomi wireless models, the battery usually takes up a significant part of the volume and can be glued to the body or installed in a special compartment.
It is important not to damage the lithium-polymer battery shell, as this can cause a new part to catch fire or fail. If the battery is held on double-sided tape, preheat its back. Contact soldering pads must be freed from the old solder before installing the new element.
⚠️ Warning: Never try to remove the battery if it swells using sharp objects - this is guaranteed to short circuit and possible ignition of the electrolyte.
When installing a new battery, make sure the polarity of the connection matches the marking on the board. A connection error can instantly disable the charge controller. Once connected, check the voltage with a multimeter before final assembly.
Repair of the dynamic head and cleaning of the grid
Often, the silent sound or the complete absence of it is caused by contamination of the protective mesh of the dynamic head. Earwax and dust can clog the holes, creating a "barrel sound" effect. To clean, use a soft toothbrush soaked in isopropyl alcohol.
If the problem lies in the dynamics, replacing it requires special care. The speaker in Xiaomi Earphones 2 can be soldered to the board or connected through a miniature connector. When dismantling, try not to pull the wires, but to take the speaker for the plastic base of the housing.
How to clean the speaker grid?
Once cleaned or replaced, check the device without assembling it completely. Connect the headphones to your smartphone and play back the test track. This will make sure the problem is solved before you snap the case back.
Comparison of the complexity of repairs of different modifications
Different versions of headphones may have different designs, which directly affects the complexity of repairs. Wired models are often easier to maintain, as they do not require battery work, but have thinner wires that are easy to snack on when handled carelessly.
Wireless versions require adhesives and lithium batteries to work, which increases the risk of damage. Below is a table comparing the main aspects of repairing different types of devices.
| Parameter | Wired version | Wireless version | TWS (in case) |
|---|---|---|---|
| Type of attachment | Plastic latches | Glue + latches | Strong glue |
| Risk of damage | Low. | Medium. | High-pitched |
| The main problem | Wire break | Battery wear and tear | Failure of one of the speakers |
| Tool. | Smear iron, spatula. | Fen, spatula, tweezers | Hair dryer, sucker, spatula. |
When choosing a repair strategy, always evaluate your skills.If you have never held a soldering iron in your hands, repairing the wireless version can be a serious challenge.
Assembly of the device and checking leakage
The final step is to assemble all the components in reverse order. Make sure all the plumes are stacked in their channels and not clamped by the body. Any pressure on the wires inside Xiaomi's compact body can cause a relapse in a short time.
To fix the halves of the body, use a special glue B-7000 or E-8000, which remains elastic after drying. Apply the adhesive with a thin layer around the perimeter, avoiding hitting the dynamic head and microphone holes.
💡
Use office clips or money bands to tightly press the halves of the case during the drying of the glue.Leave the device to dry for at least 4-6 hours for maximum strength of the connection.
Once the glue is dry, wipe the body with a soft cloth, removing the glue residue. Check all functions: charging, sound, microphone. If everything works correctly, the repair can be considered successful.
💡
Quality assembly is more important than speed: it is better to spend more time laying wires and aligning the body than to get a broken device with back half.
