Owners of popular acoustics often face the need to open the case when the warranty period has already expired and the device has ceased to function properly. TWS-The Chinese giant’s models are a delicate process that requires precision and understanding of design, as the company’s engineers often use hidden screws and adhesive joints to protect against moisture. Self-intervention may be required when replacing a battery that loses capacity over time, or when cleaning speakers from earwax blocking sound.
Before you start dismantling, it is important to understand the risks: most modern models Xiaomi Mi True Wireless do not require service by the user. cases are often made using ultrasonic welding technology, which makes them almost indissoluble without damaging the external elements. However, with a certain set of tools and patience, you can successfully repair the gadget, returning a second life without going to the service center.
In this guide, we will look at the typical opening scenarios of various modifications, from the classic Redmi AirDots to more advanced versions with active noise cancellation. You will learn what tools you need, how to not damage the plumes and where to look for hidden fasteners. The right approach will minimize the risk of breakage of fragile electronics and preserve the aesthetics of the device.
📊 What problem are you facing?
One earphone stopped working.
The volume of the sound dropped.
The battery holds the charge for 10 minutes.
The headphone just doesn't turn on.
Successful opening of an electronic device will require specialized tools that will ensure safety for both the wizard and the components of the gadget. The main tool will be plastic blades (spoogers) that allow you to penetrate the joints of the case without leaving scratches on glossy surfaces and without creating sparks that are dangerous for electronics. Metal objects should be used with extreme caution, as they can easily damage the lithium polymer battery or cut thin paths of the board.
In addition to the blades, you will need a set of precision screwdrivers, most often PH00 or Y000, as manufacturers use custom-sized screws to prevent unskilled repairs. Medical alcohol or a special liquid B-7000 for softening adhesives, which are often used in waterproof models. Heating elements such as a hair dryer or heat pad, will help warm the case, making the plastic more elastic.
The organization of the workspace is a critical step that is often ignored by beginners. It is recommended to use a magnetic mat or sorting box for screws, so as not to lose them and remember the sequence of twisting. Good lighting and a magnifier or microscope will allow you to see the smallest details and connectors, preventing errors when disconnecting the plumes.

Use a small diameter suction cup to create an initial gap between the halves of the body if there are no visible screws.
Types of structures and methods of attachment of housings
Xiaomi engineers use different build methods depending on the price segment and purpose of the device. In budget models, such as early versions of Redmi AirDots, a design is often found where the two halves of the body are simply tightly pressed against each other and fixed by internal latches. In such cases, disassembly begins with finding a barely noticeable seam and carefully moving a thin blade or blade around the perimeter.
More expensive models, including the Mi True Wireless Earbuds series with the Pro or Basic 2 index, often use a combined attachment method: several screws are hidden under silicone mounts or decorative stickers, and the rest of the body is glued together. It is important to understand that having a moisture protection class IPX4 or higher almost always involves using perimeter glue, which greatly complicates the reassembly process.
There is also a category of modular build devices where the battery board is removed as a single unit after the back cover is removed. In such designs, the main risks are connected to the plugs, which can be very short and easily break if you sloppy handling. Understanding the design type of your model will help you choose the right opening strategy and avoid fatal errors.
Hidden screws.
Where to look for them most often?: Screws often hide under silicone plugs inside the charging case, under stickers with a serial number on the inside of the earphone or deep inside the speaker channel, covered with a grid. Carefully inspect all surfaces in bright light at different angles to notice hidden holes.The process of dismantling should begin with a thorough external inspection of the device in good light. Find all the visible screw joints and remove them by first unplugging the plugs or stickers, if any. If there are no screws, you need to warm the body with a hairdryer to a temperature of about 60-70 So, if you want to take a little bit of a degree, you can soften the internal glue, but don't overheat so you don't damage the battery. Move slowly around the circle, gradually increasing the gap, and listen to clicks: the sound of cod can mean the breakage of plastic latches, so act delicately. When the body begins to diverge, do not pull the halves sharply, as inside may be connecting wires or plumes that go to the control buttons or LED indicators. The next step is to disconnect the battery from the control board. This is done by carefully pulling the connector with a plastic blade or tweezers, avoiding the use of metal tools that can cause short circuits or plumes that go to the control buttons or to be completely manipulated from the microphone. ☑️ Safe disassembly plan Take a photo of the device before disassemblyPrepare the tank for screwsPrepare the body with a hairdryer (if glued)Switch off the battery first Check the integrity of the plumesCompleted: 0 / 5 Headphone model Type of mounting Location of screws Difficulty opening Redmi AirDots 1/2 Latchers + The Latest: Mi True Wireless Basic 2 Screws. + The average Mi True Wireless Earbuds Pro + Inside the channel speaker Very high Xiaomi FlipBuds Pro Ultrasonic welding No access Extreme battery replacement and elimination of typical malfunctions The most common cause of disassembly is the failure of the lithium battery, which eventually loses capacity. After opening the case and removing the old battery, you need to pay attention to its parameters: voltage (usually). 3.7B) and overall dimensions. When replacing, it is important to choose an item with a similar connector or carefully re-sweeten the contacts, observing polarity, since an error can lead to the combustion of the charge controller. Another common problem is a quiet sound or its absence in one of the channels, which is often caused by contamination of the acoustic mesh with earwax or dust. In this case, a complete disassembly may not be necessary: carefully remove the external speaker or protective grille and clean the hole with alcohol and a soft brush. If the problem is in the dynamics itself, its replacement requires careful solder of thin wires to solve the problem of the handkerchiefs, which can also be checked by recharging the contact areas. If the board shows traces of corrosion after moisture, you will need professional cleaning with ultrasound and vertebrating chains with a multimeter. ⚠️ WARNING: When soldering inside the headphone case, use a low-temperature tin and work quickly to avoid melting plastic structural elements and damaging the thermosensitive components of the board. The assembly process is reversed to disassembly, but requires even greater attention to detail. Before joining the halves of the body, make sure that all the plumes are laid in their seats and not clamped with plastic elements, which can lead to their rubbing over time.The screws should be twisted cross-cross, gradually tightening them to avoid skewing the body and the appearance of gaps. If the model provides adhesive connection, apply a thin layer of special glue B-7000 Or a similar device around the perimeter of the joint, avoiding the substance entering the speaker or on the contacts. Once the parts are connected, the device must be fixed with stationery rubber bands or in a clutch with soft sponges for several hours until the glue is completely dry. The glue that is exposed to the outside is carefully removed after partial grasping, and the final step is to test the health: connect the headphones to your smartphone and check the sound in both channels, the microphone and the charging from the case. Make sure the lights are on correctly and the buttons or touch controls are responding to touch. If all functions are working properly, the repair is considered a successful completion. ✅ Carefully lay all wires and plumes so that they do not interfere with the closure of the lid. ✅ Use the minimum amount of glue needed to maintain future disassembly capability. ✅ Check all functions before final fixation of the body. ✅ Let the glue dry at least. 2-4 pre-existence. ⚠️ Warning: Do not use superglue (cyanacrylate) to assemble electronics, as its vapors can settle on contacts and speakers, causing corrosion and deterioration of sound quality. Frequently asked questions (FAQ) Can you disassemble Xiaomi Earbuds without damaging the body? It's almost impossible to disassemble modern ultrasonic welding models completely (without damage), but using a hair dryer and thin blades, you can minimize visible damage by making the seam almost invisible after gluing. Which battery is best to use for replacement?It is best to look for original batteries with the same labeling. If there are none, pick up an analogue with identical dimensions and voltage (3.7V), paying attention to the capacity (mAh) - it should be equal to or slightly higher than the original. What if after assembly the headphone stopped charging? Most likely, the plume was damaged or the battery connector was not fully inserted. Also, the charge controller calibration could be lost - try to discharge the headphone to zero and leave it on charge for several hours. Do I need to glue the case after repair for moisture protection? Yes, you need to restore the declared moisture protection, you need to use a special battery connector in the circuitry system for the s? They have to be found on specialized repair forums or in paid databases, often they are the method of reverse engineering by enthusiasts.
