The situation when your favorite gadget is left without its protective house, familiar to many owners of wireless acoustics. the case from Xiaomi headphones is not just a plastic box, but a complex device with a charge controller, battery and contacts. Its loss or breakdown turns the use of the headset into real torture, because without a case, you can not fully charge earbuds on the way.
Often users face the challenge of identifying the right model, especially if the original packaging has long been thrown out, and the headphones themselves have a compact design without explicit labeling. In this article, we will examine all the ways of searching, from visual inspection to the use of technical articles. You do not have to wonder whether the replacement purchased on the marketplace will work if you follow the algorithm described below.
The accessories market is full of offerings, but finding the original case or a quality copy with functional functionality can be difficult. It is important to understand that even within the same brand compatibility is not always guaranteed. Different generations of devices may have a similar appearance, but different locations of magnets or charging protocols.
Visual identification and search for markings
The first step to finding a replacement should always be to inspect the device itself. Most Redmi Buds or Mi True Wireless models have unique design features that you can't confuse with a close look. Note the shape: it can be oval, square with rounded corners or elongated like a pencil case.
So, look carefully at the inside of the lid and the bottom of the case, and that's where manufacturers often put small print with technical information: TWSEJ06LS Input: 5V⎓0.5A. This data is the key to the correct search in online stores.
⚠️ Warning: Marking can wear off over time due to constant friction in your pocket. If you can't see the inscriptions, don't use abrasives to develop them - this will damage the plastic.
The type of charging connector is also an important guide. Older models could have used Micro-USB, whereas modern models have switched to Type-C. The presence or absence of wireless charging (Qi) support also narrows the search. If there is no metal pad or characteristic indicator at the bottom of the case, wireless charging is not provided in this model.
The color of the status indicator matters, too. Some models have LEDs burning inside, others through translucent plastic, and others have hidden under the matte surface. Remember where the light bulb lights up, which will help to weed out the inappropriate options when viewing photos of products.
Use of Mi Home and articles
If the visual inspection fails, software will come to the rescue: connect your headphones to your smartphone and open the Mi Home or Xiaomi Earbuds app. The device card often displays the exact model name, which you can use to find accessories.
In the About section or in the connection settings, you can find the full technical code. For example, for the popular Redmi Buds 3 Pro, the code will differ from the regular version of Redmi Buds 3. Type this code into the search box of any large electronics store.
Why is the article more important than the title?
There is also the possibility to check compatibility via the Bluetooth menu. Sometimes when you connect a case (if it has a battery), the smartphone can display the charge level of the case itself, which confirms its serviceability and compatibility with the current firmware of the phone.
If you have a manual or a box, look for a barcode that you can scan with your smartphone camera and the search engine will immediately give you the exact match, which is the fastest way to avoid error, especially given that Xiaomi produces dozens of models every year.
Comparison of technical characteristics of cases
Even if (appearance) matches, internal performance can vary, and the critical parameter is the battery capacity of the case, which ranges from 300 mAh in compact models to 500+ mAh in wireless charging versions.
The table below will help you navigate the main differences of popular series:
| Model headphones | Case type | Battery capacity | Features |
|---|---|---|---|
| Mi True Wireless 2 | Vertical | ~400 mAh | Support for Qi, Type-C |
| Redmi Buds 3 | Horizontal | ~320 mAh | Compact, without wireless charging |
| Xiaomi Buds 3T | Oval. | ~470 mAh | Reinforced construction, IP54 |
| AirDots Pro 2 | Vertical | ~410 mAh | Dual-mode charging |
Notice the location of the magnets. Some models have them deep in the mines, others have them closer to the surface, and if the magnets in the new case are weaker or shifted, the headphones may not charge or fall off when you move abruptly.
💡
When buying a used case, be sure to check the condition of the contact areas inside the mines. Contact oxidation is a common reason why headphones stop charging even in a serviceable case.
Also consider weight. Xiaomi's original cases have a well-defined mass. If the replacement you buy feels suspiciously light, maybe there's a smaller battery inside, or cheap electronics that will quickly fail.
Where to look for original parts and compatible analogues
Finding the original case is not an easy task, as they are rarely sold separately. Xiaomi Service is the first instance where you should contact, where you can offer a replacement as part of a warranty or paid repair.
Large markets like AliExpress, Ozon, or Wildberries offer many options, but it's important to filter vendors here. Look for those who specialize in Xiaomi's technology and have high ratings. Product descriptions often list compatible models.
- 🔍 Xiaomi’s official store on the marketplace is a guarantee of compatibility, but a limited range of spare parts.
- 🛠 Specialized phone parts stores – often have catalogs with (disassembled) devices.
- 🌏 Taobao, 1688 – widest choice, but complex logistics and the risk of becoming substandard.
There are also universal wireless charging cases that you can put headphones in, which have no contacts inside, but allow you to charge the device in an induction way, if the headset itself supports the Qi standard. This can be a temporary solution to the problem.
⚠️ Warning: When ordering from Chinese sites, carefully study the reviews with photos. Often the photos in the product card do not correspond to reality, and instead of the original comes a cheap copy with poorly fitted lids.
Checking compatibility before buying
Before you pay, be sure to contact the seller. Ask for additional photos of the inside of the case. Compare the shape of the notches under your earbuds. Even millimeter divergence can lead to the lid not closing or the headphones hanging.
Check out the Bluetooth version of the protocol if you buy a case with a chip. Some advanced cases have their own memory and microcontroller, which should be friends with headphones. In simple models, electronics are passive and are only responsible for transmitting current.
☑️ Pre-purchase check
If you buy a case with your hands, ask the seller to take a video of the charging process.This is the only way to make sure that the power controller is working correctly and does not go into protection a minute after you connect.
Don’t forget the color. Xiaomi often releases limited editions in unusual colors (like the Glory Grey or Olive Green). Finding the exact color match for an older model can be difficult, so consider this nuance if you care about the aesthetic aspect.
Alternative solutions and device protection
If you can't find the original case, you can look at alternatives: Silicone patch cases won't replace the lost case, but they will protect a new or surviving case from scratches and bumps. They're inexpensive and they're sold everywhere.
In extreme cases, if the problem is only a broken battery inside the case, you can try to replace it yourself. This requires soldering skills and accuracy, since the batteries in Xiaomi cases are often glued or soldered to the board. Replacing the battery will bring the case back to life, but will violate the tightness of the case.
💡
Finding the original case by article is the only reliable way to avoid charging and pairing issues.The visual similarity of Xiaomi models is often deceptive.
Considering that some Redmi Buds are not expensive, buying an expensive original case on the secondary market may not be economically feasible, and it may be more profitable to buy a new set that includes both headphones and a serviceable case.
To prevent future loss, attach a key fob or tracker (such as the Mi Smart Tag) to your case, which will help you quickly find the device if it gets lost in your bag or home again.
