Forgot the case from Xiaomi AirDots at home, and the headphones are dead? Or the charging box broke, and you need to listen to music right now? The situation is familiar to many owners of wireless gadgets. Fortunately, charging headphones without a case is possible β but with reservations. Not all Xiaomi models support alternative ways of charging, and the wrong actions can bring the device down.
In this article, we will discuss 5 working methods to power headphones Redmi Buds, Haylou, Mi True Wireless and other popular models without the original case, tell you the risks of homemade solutions, and give a checklist for safe charging, and also reveal a secret method that few people know about (spoiler: it is associated with magnetic induction).
Importantly, not all methods are universal. For example, headphones with a charging type βpogo-pinβ (contact pads) are easier to recharge than models with wireless induction. But Xiaomi FlipBuds Pro or Buddy without a case to charge is almost impossible β their batteries are programmed to work only through the original box.
Before you start, check:
- π Headphone model β the choice of method depends on this (see the compatibility table below).
- π Type of connector: Type-C, Micro-USB or contact pogo-pin?
- β‘ Stress: Most headphones need to be exactly 5V β It can also burn the controller.
If you're willing to take risks (and that's always a risk!), read on. But remember, Xiaomi's warranty doesn't cover damage from emergency charging.
1. Charging through USB-Cable: Is it suitable for your model?
The most obvious way is to connect the headphones directly to the power source through USB. But there are pitfalls here: most Xiaomi models don't have a built-in one. USB-The exception is some hybrid headphones (e.g. Xiaomi Hybrid Pro). HD), which can be charged both through the case and separately.
If your model is a βuniversalβ model, the algorithm is simple:
- Find a Type-C or Micro-USB connector on the headphone case (usually on the leg).
- Connect the cable to the power supply (5V/1A β no more!).
- Wait for the charging indication (usually a red/orange LED flashes).
Directly supported models USB-charging:
| Model | Type of connector | Max. Charging current. |
|---|---|---|
| Xiaomi Hybrid Pro HD | Type-C | 500 m. |
| Mi In-Ear Headphones Pro HD | Micro-USB | 300 m. |
| Redmi AirDots 3 Pro (left earphone only) | Pogo-pin (needs an adapter) | 400 m. |
β οΈ
Warning: Never use Quick Charge (VOOC) or laptop power supplies (19V). The headphone controller is not designed for high voltages - this will lead to overheating or short circuit.
2.Using a Power Bank or phone as a donor
If the headphones support reverse charging (e.g. Redmi AirDots 3 Pro), you can recharge them from another device.
- π± Smartphone with function OTG (Xiaomi has supported the Redmi Note 7 since).
- π OTG-adapter (or Type-C cable) β Type-C).
- β‘ Power supply: Power Bank, phone or even laptop.
Step-by-step:
Turn it on. OTG-mode on the phone (in settings) β Additionally. β OTG)
Connect. OTG-phone adapter
Connect the adapter to the headphone cable
Wait 10-15 seconds β the charging indicator should light up
-->
πΉ Important: Not all headphone models support this method. For example, Mi True Wireless 2 does not have back-to-back protection, so charging them from the phone can discharge the smartphone battery rather than the headphones.

If the charging indicator does not light up, try to turn the cable over - sometimes the pogo-pin contacts need to be pressed with force.
Homemade adapter for contact headphones (pogo-pin)
Most Xiaomi headphones (such as Redmi AirDots or Haylou GT2) are charged via a pogo-pin. If the case is lost, you can make a temporary adapter from improvised means.
- π Old charging cable with Micro-USB or Type-C connector.
- π§² Two small magnets (can be pulled from unnecessary electronics).
- π Insulation or heat-glue.
- β‘ power supply 5V/1A (for example, charging from the phone).
Assembly instructions:
- Disassemble the cable, expose the wires + (red) and - (black).
- Seal or attach wires to magnets (polarity is important!).
- Attach the magnets on the headphones so that they coincide with the contact areas.
- Connect the cable to the power source.

Warning: This method requires precise soldering and polarity, and if you fail to do so, you'll short-circuit or damage the battery. If you're not sure about your skills, you'd better go to a service center.
Critical: Xiaomi Mi True Wireless 2 headphones have left-hand charging protection, and if connected incorrectly, they can lock and require a reset via the Mi Home app.
What if the headphones do not turn on after homemade charging?
4 Wireless charging: myth or reality?
Some users try to charge Xiaomi headphones via Qi wireless charging, putting them on the platform of a smartphone or Power Bank.This only works for models with induction charging support (for example, Xiaomi Air 2 Pro or FlipBuds Pro), but there are nuances:
- β Supported models: Only those with the Qi Wireless Charging label.
- β Problems: Headphones must lie strictly in the center of the charging pad, otherwise contact will be interrupted.
- β‘ Power: Maximum 2W β charging 3-4 hour.
πΉ How to check for support:
- Check out the model features on the official Xiaomi website.
- Try putting your headphones on the phoneβs charging pad (like the Xiaomi 11T Pro). If the light is on, itβs supported.
β οΈ
Warning: Do not put your headphones on charge with metal objects (keys, coins) and this can cause overheating and battery damage.
5. Emergency method: charging from another case
If you have access to the case from other wireless headphones (like friends), you can try charging Xiaomi through it.
- π Case has the right contacts (e.g. Haylou) GT1 Redmi AirDots is compatible).
- β‘ Case tension is exactly 5V (Check the technical specifications).
- π The size of headphones allows you to place them in someone else's case.
Step-by-step algorithm:
- Clean the contacts of headphones and case with alcohol.
- Place the headphones in the case so that the pogo-pin contacts match.
- Close the lid and wait 5-10 minutes - the indicator should light up.
- If the charge is not going, try to turn the headphones over.

This method is suitable for emergency cases, but not for permanent use. Alien case can supply unstable voltage, which reduces the battery life.
6. Alternative methods: solar panel and USB-hub
If you are on a hike or far from the outlet, you can use portable solar panels or USB-It's a battery-powered hub:
- βοΈ Connect the solar panel (5V) Power Bank, and then headphones via adapter.
- π Use it. USB-battery-base AA (need a voltage stabilizer!).
β οΈ Risks:
- π‘οΈ Solar panels give unstable voltage - overheating is possible.
- π Batteries. AA can be issued 1.5V on the element - you need to accurately calculate the scheme.

If you travel frequently, buy a portable case with replaceable batteries (such as the Baseus Blade). TWS-headphones, including Xiaomi.
Frequent Mistakes and How to Avoid Them
When charging headphones without a case, users often make critical errors that disable the device.
π₯ Top.-3 errors and consequences:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of charging >5V | The power controller burns. | Check the voltage with a multimeter |
| The wrong polarity in soldering | Short circuit, battery bloating | Mark + and - with a marker |
| Charging from a laptop (USB 3.0) | Unstable current β rapid wear of the battery | Use USB 2.0 or Power Bank only. |
β οΈ
Warning: If the headphones start to warm up or discharge quickly after charging, stop using immediately! These are signs of battery damage. Further operation is dangerous - the battery may swell or ignite.
