Loss of components for popular electronics is a common problem faced by wireless headphone owners. Xiaomi Airdots 2, also known as Redmi Airdots, are no exception: their compact design often leads to the fact that the charging case goes unnoticed in the pocket of clothes or falls out of the bag.
There are several scenarios where users are looking for a way to find or replace the accessory, where some are trying to find a lost case at home, hoping for its technical capabilities, while others urgently need a replacement for a lost one to continue operating. TWS-It's important to separate these tasks, because the solutions are fundamentally different.
In this article, we will discuss in detail the physical and software search methods, as well as expert advice on purchasing compatible equipment, you will learn why a Bluetooth signal does not always help in finding a case and what to look for when buying a new charging base. Understanding the technical nuances will save you time and money.
Technical limitations of Bluetooth case search
The first thing that Xiaomi Airdots owners need to learn is that the charging case itself does not have a Bluetooth module and does not connect directly to the smartphone. Only the headphones (left and right) that are inside the phone communicate with the phone, which means that if the headphones are inside the case and the cover is closed, they go into charging mode and break the connection to the outside world.
Many users mistakenly believe that a search function similar to Apple’s Find My will allow you to track the location of the case through the application. However, the architecture of the data protocol in Xiaomi budget models does not provide for a permanent background broadcast coordinates with a case.
The only technical chance of finding a case through the phone is if one of the headphones is outside the case or if the case cover is open and the earphone is trying to connect to the phone, in which case you can hear the characteristic connection sound or see the status of the battery on the smartphone screen. However, this only works at a very short distance, usually not exceeding 5-10 meters in line of sight.
It's also worth noting that even if the headphones are in the case, but the lid is open, they can maintain a connection, in which case, by moving around a room with a loud sound on the phone (for example, by running a test track), you can try to hear a squeak or voice from the headphones, which is an acoustic search method that is often more effective than software.
Physical search methods for lost case
If software methods are powerless, you have to rely on logic and mindfulness. Visual inspection is the first and most reliable step. The case from Xiaomi Airdots 2 has a glossy surface that can shine when light hits. Use your smartphone flashlight while driving a beam at a sharp angle along the floor, under sofas and in the folds of clothes.
Often cases get stuck in the lining of bags or jacket pockets, especially in winter when we wear a lot of things. Check all the pockets of clothes you've worn in recent days. The mechanism of latching the lid on this model is quite tight, but with sudden movements, the case could slip out unnoticed. Pay special attention to small pockets and key compartments.
Try to replay the last moments you used your headphones: Where did you take them out? Often, the case is left on your desktop, on the shelf in the store or in the car. If you use public transport, the chances of finding what you lost there are extremely low, so focus on your regular places of stay.
💡
Wipe the surface where the case was supposedly lying with a wet wipe to remove dust – the glossy black plastic will become more noticeable in contrast.
What to do if the case is lost irretrievably
When the search fails, the only option is to buy a new charger. The original case for Xiaomi Airdots 2 (TWSEJ06LS model) can be found in official service centers or with authorized partners. However, it is often easier and cheaper to purchase a compatible counterpart that is functionally equal to the original.
When buying a new case, it is critical to check the model of your headphones. Xiaomi Airdots 2 have a specific shape and location of contacts, different from the first version (Airdots 1) and the model Airdots 3. Incorrectly selected case may simply not charge the headphones due to the mismatch of contact pins.
Pay attention to the charge indicators. In the original models, they are located on the front panel and light up in red or white depending on status. When buying a used or new case on marketplaces, be sure to check with the seller for compatibility with version 2 or Youth Version.

Comparison of the original case and analogues
The accessories market is full of offers, and it can be difficult to choose a quality replacement. The original from Xiaomi is characterized by high quality plastic and accurate calibration of the charge controller, which prolongs the life of the lithium polymer battery inside the headphones. Cheap analogues can have a voltage spread, which is undesirable for long-term use.
However, many third-party manufacturers make great copies. The main difference is often in weight and tactile sensations. The original case has a characteristic weight and a matte-gloss coating that collects less prints. The analog can be made of cheaper plastic that scratches faster.
Below is a table to help you compare the key characteristics of the original and typical analog:
| Characteristics | Original Xiaomi | Quality analogue | Cheap copy |
|---|---|---|---|
| Case material | Dense ABS plastic | ABS plastic | Thin brittle plastic |
| Indication | Accurate (4 levels) | Basic (charge/no) | Often absent |
| Magnets | Strong, fixed securely | Average. | Weak, headphones fall out |
| Price. | Tall. | Medium | Low. |
When choosing a replacement, also consider the availability of a warranty. Original accessories in service centers can give a warranty of up to 6 months, whereas in the electronics markets you will most likely only be offered an on-site inspection of the goods.
The mating process with a new case
Once you buy a new case, users often face a problem: the headphones don't charge or see each other, and this is because the left and right channels have to be synchronized through the case. Just inserting the headphones is not enough - often a reset procedure is required.
To start, place both earbuds in a new case and make sure the charging indicators (usually red) are on fire. If the indicators aren't burning, wipe the contacts on the headphones and inside the case with an alcohol wipe - oxidation or fat can interfere with charging. Then remove the headphones at the same time.
If the automatic connection does not occur, manually reset. To do this, press and hold the touchpads on both headphones for 5-10 seconds until the indicators flash red. Then place them back in the case, close the lid and re-extract to pair with the phone.
What to do if only one indicator is on?
Before the first full operation, set it on charging for at least 30-40 minutes along with headphones to activate the power controller.
Common errors in operation and replacement
One of the most common mistakes is to ignore polarity and purity of contacts. Users often forget that getting moisture or sweat on headphone contacts when you put them in a case can cause short circuit or corrosion. Always wipe your headphones before you put them away for storage.
Another mistake is using powerful chargers to charge the case itself. Although modern controllers are able to limit current, using power supplies that support Quick Charge or High Voltage Power Delivery can overheat a cheap battery inside the case. It is recommended to charge the case from the standard USB-port of the computer or unit on 1A.
⚠️ Warning: Never try to open the case yourself to replace the battery, and there is a lithium cell inside that can cause fire damage, and you will also break the tightness of the case.
Also, users often confuse display modes. Blinking red light can mean not only low charge, but also a pairing error. Carefully study the device manual to correctly interpret LED signals, as they may differ in different firmware revisions.
💡
Proper hygiene of contacts and the use of weak charging currents prolong the life of the case by 2-3 times.
Where to look for original parts and accessories
If you’re looking for the original case, start your search with Xiaomi’s official service centers in your city. Even if the item isn’t available, they can order it from a warehouse or prompt an article to search. The official charging box article for this model is often labeled TWSEJ06LS, but it’s better to double-check it by IMEI or headphone serial number.
Large marketplaces also offer original parts, but there is a high risk of running into a high-quality fake (the so-called "replica"). Read reviews, pay attention to the packaging: the original always comes in a branded box with a hologram and QR-authentication.
Don't discount Xiaomi's forums and hobbyist communities. They often sell cases from broken or lost headphones. This can be a great way to buy original items for a used price. However, when buying from hand, be sure to demand a video of a working case with your headphones.
⚠️ Note: When buying a case in the secondary market, be sure to check the voltage on the contacts with a multimeter, if possible. It must be stable and meet the declared characteristics (usually about 4.2V for a charged Li-Ion).
Finding or replacing a case for Xiaomi Airdots 2 is a solvable task, but requires attention to detail. Bluetooth technical limitations do not allow you to find the case remotely if the headphones are inside, so the main emphasis should be on physical search or purchase a quality replacement.
