Xiaomi Redmi headphones are some of the most popular wireless gadgets on the market due to their combination of price, sound quality and functionality. However, over time, even the most reliable equipment has to be repaired, whether it is replacing the battery, cleaning the speakers from dust or recovering from a fall. The main problem is that the manufacturer does not provide easy access to the insides of the device, and careless disassembly can damage the plumes, buttons or microphones.
In this article, we will learn how to open Xiaomi Redmi headphones from different models, from the budget Redmi AirDots to the flagship Redmi Buds 4 Pro. You will learn what tools you need, where the hidden latches are located, and how to avoid typical disassembly errors. And we will share unique mounting schemes for models from 2023 to 2026, which are not described in the standard instructions.
What Xiaomi Redmi models can be disassembled independently
Not all Xiaomi headphones are disassemblable at home, such as monolithic models like the Redmi Buds 3 Lite are glued so tightly that their opening almost always ends in a broken case, while other versions are modular and deal with minimal risk:
- 🎧 Redmi AirDots (1/2/3 generation – classic form with plastic latches inside.
- 🎧 Redmi Buds 3/4 Pro – a more complex design with silicone inserts, but with access to the battery.
- 🎧 Redmi Buds 4 Active - simplified disassembly thanks to the magnetic mounts of the body.
- 🎧 Redmi AirDots S - budget model with minimal glue.
If your model is not on the list, it doesn't mean it can't be disassembled, but the risk of damage increases by 2-3 times, for example, Redmi Buds 5 have ultrasonic welding of the case, and they will require professional equipment to open them.
⚠️ Note: Disassembling Xiaomi headphones automatically deprives you of warranty. If the device is warranty service, contact the service center - especially if the problem is related to the battery or microphone.
Preparation: security tools and measures
Before you start dismantling, prepare the workspace and tools.
- 🔧 Plastic mediators or shoulder blades (metallic can scratch the body).
- 🔧 Tweezers with thin ends for working with plumes.
- 🔧 Hair dryer or thermo-air station (to soften the glue if the body is glued).
- 🔧 Isopropyl alcohol (90%+) clean-up.
- 🔧 Silicone mat or soft fabric so as not to scratch the body.
- 🔧 Lupus or magnifying glass for working with small details.
We also recommend using an antistatic bracelet to avoid damage to electronic components by static electricity. If it is not, regularly touch grounded metal objects (for example, a heating battery).
Before you start, completely discharge the headphones, which will reduce the risk of short circuits in case of accidental contact with the board. Also take a picture of each stage of disassembly, this will help to properly assemble the device back.
Step-by-step instructions: how to open the headphone case
The disassembly algorithm depends on the model, but the general scheme looks like this:
Remove silicone embusures (if any)
Warm up the body with a hair dryer (temperature 60-70 ° C, not higher!)
Put a mediator in the seam between parts of the body
Carefully disconnect the latches around the perimeter-->
Let’s look at the Redmi AirDots 3 example:
- Remove the bottles (if any) and clean the case of dust with a dry wipe.
- Find the seams between the front and back on the body – usually closer to the bottom of the headphone (from the microphone side).
- Warm up the seam with a hair dryer for 1-2 minutes, holding the device at a distance of 5-7 cm. the glue will become softer, and the risk of breaking the latches will decrease.
- Insert a plastic mediator into the seam and rotate it gently to separate the latches. Start at the button side, which is usually less glue.
- Once the hull starts to yield, slowly move the mediator along the seam until both parts are separated.
Redmi Buds 4 Pro process is more complicated due to the additional mounts near the speaker, which will help the following trick: after warming up with a hair dryer, easily tap the body with the blunt side of the mediator, which will help to "stick" the glue.
What if the body does not yield?
Typical Disassembly Problems and How to Avoid Them
Even with careful work, you can run into trouble, and here are the most common mistakes and ways to prevent them:
| Problem. | Reason. | Decision |
|---|---|---|
| Broken hull latches | Excessive force in separation | Use mediators with rounded edges and warm up the body longer |
| The button plume is damaged. | Improper collection of fees | Fix the fee with tweezers behind the edges, do not pull the plumes |
| The speaker detached. | The adhesive speaker melted when heated | Do not direct the hair dryer directly to the speaker, use gentle mode |
| The microphone does not work after assembly. | Infection of dust on contacts or incorrect position of the membrane | Blow the contacts with compressed air, check the position of the microphone |
Pay special attention to the battery. If it's swelling, do not puncture it or heat it above 60°C, it can lead to fire. The bloated battery must be removed with gloves and disposed of immediately.
⚠️ Warning: If the headphones stop turning on after disassembly, check the charging pad contacts on the board. Often they become oxidized or contaminated, which blocks the power supply. Clean them with alcohol and a soft brush.
How to collect headphones back: tips for sealing
Assembly is as important as disassembly, and if you don't connect the body properly, the headphones can lose their water protection (if they had one), or dust will get in.
- 🔄 Before assembly, check all plumes and contacts - they should be clean and flat laid.
- 🔄 If the body is glued, use bilateral tape. 3M or a special glue for electronics (for example, Loctite 406).
- 🔄 For models with latches (such as AirDots 2), check the integrity of plastic latches – if they are broken, the body will not hold.
- 🔄 After assembly, check the tightness by blowing into the microphone - if you hear a whistle, then there are cracks.
If you've been replacing your battery, charge your headphones 50 percent before you're finished, and check your battery life, and if it's significantly lower than the battery you're claiming, it's possible that the new battery is poor or not connected properly.
💡
For better sealing after assembly, wrap the headphone case with food film for 1-2 hours - this will help the glue evenly distribute and "grab".
When the Disassembly is Inappropriate: Alternative Solutions
Sometimes it costs more to repair Xiaomi Redmi headphones than to buy new ones, and here are some cases where it’s better to give up disassembly:
- 💥 Damaged board (visibly blackened or burned elements).
- 💥 Broken speaker – replacement will cost 70-80% of the cost of new headphones.
- 💥 The body cracked - even after gluing, the tightness will be broken.
- 💥 Ultrasonic welding of the body (typical for models 2023)+ year-end).
In such cases, consider alternatives:
- 🔄 Sale for parts – working speakers, batteries or boards may come in handy to others.
- 🔄 Trade-in exchange (in some stores they give a discount on new headphones when handing over old ones).
- 🔄 Use as a “donor” – for example, if you have a pair of headphones where one works and the other doesn’t.
If you still decide to repair, but are not confident in their abilities, contact specialized workshops. the cost of dismantling in the service is usually 300-800 rubles (depending on the model), which is cheaper than the risk of finally breaking the device.
