How to Charge Xiaomi Redmi Airdots and What to Do If One Earphone Is NOT Charging in the Case (Right or Left)

Lifehacks

After purchasing the headset, immediately charge it to 100%. Unfortunately, it is impossible to find out the exact level before connecting to a smartphone, so we are waiting for a white, non-blinking indicator to appear. If the earbuds have not been used for a long time, you must first connect the case to power, and after 100% of the volume, insert the device into it.

Use the factory cord. There is no power supply included, so any external battery will do: a computer or a power bank.

We told you how to charge Xiaomi and Redmi wireless headphones. Write in the comments which model you use.

How to charge the Redmi AirDots case

The earbuds are powered by a charging case, which acts as a Power Bank. Its battery capacity is 300 mAh, which is enough to charge the plugs 3.5 times. To charge the case, connect it to a power source using a USB-A to microUSB cable. Use the USB port of a laptop or computer as storage, or connect an external battery.

Important! When connecting to a power adapter from a smartphone or tablet, make sure it is compatible with the case. Charging too powerfully can damage the power connector and cause rapid battery wear.

To understand whether the box is charged or not, a two-color indicator is displayed on the case, which has 3 states:

• lights up white – the case is connected to a power source;
• blinks red every 3 seconds – low battery charge;
• The indicator lights up red for 10 seconds after being placed inside the headphones - the battery is completely discharged.

It will take 1 hour 40–50 minutes to completely restore the case without headphones. If discharged headphones are placed inside, charging will take more than 2 hours. The difference between recharging the battery from a PC/laptop or a charger is minimal, since the connector limits the incoming power.

Note! The cases of wireless headphones from Redmi and Xiaomi do not have moisture protection, so it is recommended to keep them in a dry place.

Redmi AirDots headphones do not charge

If, after spending time charging, the case or headphones are discharged/recharged to a minimum:

• Check the charging level of the case. The LED on the case may fail or begin to glow dimly, making it more difficult to determine the remaining battery life;
• Clean the microUSB connector on the case. When it is in a pocket/bag, dust, dirt, and clothing fibers become clogged with it, resulting in poor contact. To clean, use a toothpick and a can of compressed air. Do not blow through the connector with your lips together: moisture will get inside, which can cause oxidation of the contacts;
• check the charging cable. It could become pinched, resulting in damage to the contacts. Use other devices for this or take a different cord;
• clean the contact pads. If one earbud is not charging, dirt may have gotten into its recess and is preventing normal charging. Use a toothpick to remove debris. You can wipe the recess with an alcohol-containing product by applying it to a cotton pad and squeezing it thoroughly so that the liquid does not get inside;
• battery degradation. The headphones or case are not charging due to loss of battery capacity. The reason for this could be a long period of inactivity, use at low or high temperatures.

When it is not possible to determine the cause of the malfunction or it appeared after a fall or impact, you should contact a service center for advice.

Now you know how to charge and determine the remaining battery capacity on wireless headphones and Xiaomi/Redmi AirDots case. Any user can have problems with headphones, and there is also a high chance of buying a fake instead of the original headset.

Advantages and disadvantages

Any device has its own advantages and disadvantages. Xiaomi Airdots are no exception. The advantages include:

• clear speech transmission by microphone;
• presence of noise reduction;
• cost (you can purchase them for about 4,000 rubles);
• design;
• high-quality materials used to create the accessory;
• convenient control;

Reviews from real customers

They don’t fit very well in your ears, or rather it’s like this: you take headphones from Apple, put them in and it’s almost the same thing, but the headphones from Apple sound, but the Mi Air 2 doesn’t sound.

And you take these headphones, you begin to somehow press them more into the auricle, try to find some position for these headphones that will improve the sound and this happens a little, but in reality you still think how terrible they sound. Yes, of course, they are quite convenient to use as a headset; you take them out, put them in, they connect to the phone very quickly.

To make them sound normal, they need to be re-flashed.

What you need to know before charging

Let's note the important points:

1. Do not use over-ear, on-ear, or neck-mounted headphones while charging to avoid damaging the battery.
2. The case can be charged with headphones, without them, or with just one while the second one is in use.
3. It is not necessary to turn off Bluetooth when connecting the ears to the charger; just pause the music or video playback.

Read the user manual included in the kit or on the manufacturer's website, which specifies handling features for a specific model.

Unboxing

The first thing buyers pay attention to is high-quality packaging made of thick coated cardboard.

Packaging with Xiaomi Airdots Pro 2 headphones

It shows the headphones themselves and the model name. Inside the box there is a case with the headphones themselves inside.

Case with headphones inside

Standard equipment:

Equipment Xiaomi Airdots Pro 2

It takes some effort to get the headphones out. They are set deep inside the case, which creates certain inconveniences. Each earphone weighs about 4.5 grams. There is not enough mechanism that can push the earphone out of the case after pressing. This is one of the disadvantages of the gadget. The headphones feel quite good in the ears. This does not create any inconvenience during their use.

The headphones feel quite good in the ears and do not create any discomfort.

How long do they last to charge?

An equally important issue concerns the operating time of the headset. If you know how long it takes for Xiaomi wireless headphones to charge and have clearly maintained this period, the operating time can range from 4 to 12 hours. Much depends on the battery capacity, frequency of use, volume and other factors. More precise parameters can be easily found in the operating instructions.

Now you can imagine how long it takes to charge wireless devices, how to find out the charge of Xiaomi headphones, and how long they can work offline. In the comments, tell us whether you managed to complete the work according to the instructions, what difficulties arose, and whether you were able to solve them.

Precautions and useful tips

We've figured out how to charge the most popular models of headphones and headsets. And now a few recommendations for use, adhering to which we will significantly extend the life of the device:

1. Before using the device, carefully read the user manual. Using the “poke method”, the headset can easily be damaged by simply pressing a button or connecting it to the wrong charger.
2. Before first use, fully charge the headset and case, if any.
3. We do not use network adapters of dubious origin and unknown manufacturer. Even if the characteristics we need are indicated on the body of such a memory device, it is not at all a fact that the reality corresponds to what is written. And the reliability of such power supplies leaves much to be desired.
4. We try not to use the device while it is charging. Having gotten used to a wireless connection, we may forget that we are “tied” to the charger and simply rip the socket out of the headset body.
5. Do not leave headphones in the sun or near heating devices. Elevated temperatures significantly reduce battery life and negatively affect sound-emitting capsules.
6. We do not abuse excessive volume. The headset is not intended for listening to loud music. By turning the volume up to 100%, we significantly reduce the life of the sound-emitting capsules, and they will very quickly wheeze or even burn out.
7. We do not store the headset and case for a long time with discharged batteries. Charge a completely dead battery as soon as possible.

Advantages

1. Nice matte case,
2. USB type-c
3. LED charging indicator
4. Fast charging of the case ( 1 hour )
5. Stays well in the case
6. There is a touch panel on the back of the headphones (you can stop the music, play the next track, answer or reject a call, call a voice assistant)
7. They have a built-in high-quality LHDC codec (for Xiaomi Mi 9 Pro 5G smartphones and some Huawei smartphones that also support this codec)
8. Bluetooth 5.0 , headphones quickly connect to the device

Hardware check

Experienced users and service center technicians assess the condition of the battery using a multimeter. The method is applicable if there are problems with charging or lack of indication on the case.

Remove the panel with sockets for AirDots. Connect the analyzer contacts to the input terminals on the battery. The voltage value is displayed on the display, which indicates the functionality of the battery.

Monitoring the charge level of the case is an important aspect of comfortable use of the earbuds. Owners of AirDots Pro can view the energy level of the box. Users of other models determine the remaining operating time based on the light indication.

How long to charge wireless headphones

Charging time is determined by the power source and battery capacity. This is what the average values ​​look like for each type of wireless headphones if you use chargers recommended by the manufacturer:

• TWS (in-ear, in-ear) – 1-3 hours;
• with neck fastening – 1-4.5 hours;
• overhead and full-size – 2-6 hours.

The case is charged separately, which takes 1.5-3 hours.

There are headphones available on the market that support fast charging, which can charge you for 1.5-3 hours of music listening in 10-15 minutes.

Ergonomics, ease of use

Ergonomics is primarily determined by the design of the headphones - they are in-ear, because... called vacuum or plugs. They themselves are very miniature and light. They fit well and don’t fall out, but due to the shape factor you won’t be able to wear them for a long time.

The headphone case, on the other hand, is not compact; its thickness does not allow it to be carried comfortably in a pocket. The lid of the case is not firmly fixed in the open position, but it does not close either. The headphones themselves sit tightly in the case due to magnets, which makes it not very convenient to take them out.

Next, we will tell you how to turn on redmi airdots 2, how to wear it and switch music.

The headphones turn on automatically when you take them out of the charging case, if they are turned off and not in the case, to turn them on you need to hold the redmi airdots2 control button for about 1 second until the white indicator lights up.

The photo below shows how to wear redmi airdots 2 correctly –

Control.

The standard headphone control functions are quite limited. You will not be able to change the volume level using the control buttons; in order to switch the music on the redmi airdots 2 you will need to use a voice assistant, smart bracelets and watches, or program controls using third-party applications.

Sound quality

The redmi airdots 2 sound is slightly different from the first version of the headphones, partly due to a reduction in the bitrate. In any case, without serious equipment for measuring the frequency response, signal-to-noise ratio, etc. Talking about sound quality is a subjective matter. And in the case of vacuum headphones, it also very much depends on the correct selection of the size of the ear pads and wearing them.

You will not be disappointed with the sound quality of the original redmi airdots 2, taking into account their cost, of course. There is enough bass, the highs are not knocked out, but at high volumes they begin to become “sandy” as expected.

By the way, the volume reserve is sufficient, and if your airdots 2 play quietly, they most likely need to be cleaned or reset.

But the microphone remained the same - just as bad

How to charge wireless headphones from different brands

There are no specific ways to charge headphones from different vendors. Be it a model from Google, Apple, Samsung, Sony, Jabra or JBL - they all restore charge using one of the methods described above. The main thing is not to forget that you need:

• find information about the recommended power source, and do not exceed the specified values;
• Use the original or equivalent quality cable.

Of all the brands, the Chinese company distinguished itself in terms of charging, producing TWS models i7s, i8, i9 and others. What is their feature:

• the first completely wireless headphones were sold without a case, and the “ears” were charged directly through the included cable;
• After the release of models with a case, to charge the latter, you need to press the button located on the case.

In 2022, even the cheapest Chinese headphones are charged in the standard way.

Charging wireless headphones is practically no different from that for smartphones, tablets, smart watches and other portable equipment. It is important to consider the power of the power source and use high-quality cords.

Connection and software

The headphones are paired with a phone (tablet, computer) via Bluetooth v 5.0.
