Owners of the popular Xiaomi Redmi AirDots 2 wireless headphones often face situations when the device stops working correctly.
The cause may be moisture, reduced battery capacity or simply contamination of the dynamic grid, which requires immediate intervention.
Self-disassembly allows you to save significant money on service, but requires extreme accuracy and understanding of the design of the gadget.
In this article, we will take a closer look at the dismantling process, the tools needed, and the common mistakes that beginners make when they first come into contact with electronics.
Preparation of the workplace and necessary tools
Before you start the physical impact on the case, you need to organize a comfortable and safe workspace, as small parts are easy to lose.
You will need a set of precision screwdrivers, as screws in such devices usually have non-standard threads or microscopic dimensions.
Be sure to prepare a plastic blade or mediator to open the latches so as not to damage the glossy plastic of the case.
⚠️ Note: Using metal objects to lid can result in short circuit or irreversible deformation of the housing, so use only dielectric tools.
Also, don’t forget to use tweezers to extract small plumes and B-7000 glue for subsequent sealing.
- 🔧 Set of screwdrivers (cross and flat small sizes)
- 📱 Plastic blade or mediator
- 🧲 Tweezers with antistatic coating
- 🧴 Clay. B-7000 analogue
- 🔦 Powerful lamp or magnifier for working with small elements
☑️ Ready to disassemble
Quality lighting is critical, as Redmi AirDots 2 has a very dense layout of internal components.
Anatomy of device and access point
The design of Xiaomi Redmi AirDots 2 is made on the principle of a monoblock, where external screws are completely absent, and all mounts are hidden under silicone mounts and decorative elements.
The main body consists of two hemispheres connected by plastic latches around the perimeter, which requires a uniform distribution of force during opening.
Inside is a lithium-polymer battery, a control board with a Bluetooth module and a dynamic emitter connected by thin plumes.
Understanding the internal structure helps to avoid breakage of fragile contacts during careless movement.
Hidden construction
Many users mistakenly believe that it is enough to simply lid, but without knowing the location of the internal stops you can break the case.
The process of dismantling the outer shell
Start disassembly should be with careful extraction of the silicone nozzle, which closes access to the internal grille speaker.
After removing the nozzle, you need to carefully examine the inside of the bowl, where screws can hide, although this model often uses a latch system.
Use a thin plastic blade to walk around the perimeter of the junction of the halves of the body, sequentially snapping the locks.
⚠️ Note: Do not put too much effort if the body does not diverge, you may have missed a hidden screw or latch at the bottom.
Movements should be progressive and soft, so as not to damage the plume connecting the two halves of the body.
Often, the control plume is glued to the inner wall, and a sharp jerking movement can lead to its break.
- 👂 Take off the silicone ambushell
- 🔍 Check the insides for the presence of screws
- 🛠 Put the joint in a circle.
- 👐 Carefully separate the halves of the body
If you feel resistance, it’s better to stop and double-check for additional mounts than risk the integrity of the plastic.
💡
Warm up the body with a hair dryer at a minimum temperature for 30-40 seconds - this will soften the factory glue and simplify the opening of the latches.
Disconnection of plumes and retrieval of boards
After successfully opening the case, you will have access to the main board, which is the “brain” of your Redmi AirDots 2.
The first thing to do is to disconnect the battery to eliminate the risk of short circuits during further manipulation of the electronics.
The plume connectors usually have latches that need to be gently bent with a nail or plastic tool before being removed.
The board is fixed on special seats and can be additionally fixed with screws that should be twisted.
| Component | Type of attachment | Risk of damage | Tool. |
|---|---|---|---|
| Battery | Glue base + connector | High (puncture) | Plastic, hair dryer |
| Dynamician | soldering or connector | Middle (cliff) | Tweezers |
| Management fee | Screws + grooves | Low. | Screwdriver. |
| LED | Paying. | Medium (slip) | A soldering iron |
When removing the board, pay attention to the location of the antenna, which is often a wiring glued to the body.
Do not pull the charge for the wires, take only for the textolite or special technological holes.
💡
The main rule when working with a board is never to pull the wires, only for the hard parts of the components.
Battery replacement and speaker cleaning
The most common reason for disassembly is the replacement of a failed battery, which eventually loses capacity.
The battery in Xiaomi Redmi AirDots 2 is glued to the body, so it will require careful tweaking with a plastic blade to extract it.
The new battery should have exactly the same dimensions and voltage, usually 3.7V, so as not to damage the charge controller.
After installing the new battery, the voltage on the contacts must be checked before final assembly.
- 🔋 Carefully tuck in the old battery
- 🧹 Clean the seat from glue residues
- 🔌 Connect a new battery
- 🧪 Check the voltage with a multimeter
In parallel with the replacement of the battery, it is recommended to conduct a deep cleaning of the dynamic mesh from earwax and dust.
Use a soft brush and isopropyl alcohol to clean the mesh, avoiding fluid entering the speaker.
Assembly and testing of the device
The assembly process is a mirror image of the disassembly, but requires the use of adhesive composition to restore tightness.
Apply a thin layer of B-7000 glue around the perimeter of the junction of the halves of the body, avoiding getting glue on the dynamic mesh and contacts.
Connect the halves of the body and tightly press them against each other, fixing the position with a rubber band for 15-20 minutes before the initial grasp.
After drying the glue, it is necessary to check the operation of all functions: pairing, sound and microphone operation.
⚠️ Warning: Do not turn the device on immediately after gluing, allow the glue to be fully polymerized within 24 hours for maximum strength.
If the headphones are not turned on, check the correct connection of the battery connector and the absence of compressed plumes.
A well-constructed assembly ensures that the device will last for a long time without the need for repeated intervention.
