Let’s start with the case. In our case it is made of white plastic (yes, there is also a black version of the headphones). The material itself is matte and very pleasant to the touch. The front of the case only has a charge level indicator. If it blinks it’s time to charge it up, if it’s just lit up you don’t need to charge it.

The dimensions of the case are 52 x 41 x 34 mm. I should add that it is quite thick and it is not very comfortable to wear it in a jeans The case won’t fit into the smallest of s. On the back there is technical information,

And on the right edge is a special button that you press and hold for about 2 seconds to start pairing with your smartphone.

On the bottom face there is a USB Type-C port for charging.

The case opens nice and easy. It is easy to do it with one finger. The white LEDs on the box and headphone light up immediately.

Headphones themselves are also made of matte plastic, very pleasant to the touch.

Inside the box are magnets that hold the headphones very securely and terminals for charging.

On the bottom of the earpiece there are also charging contacts and a microphone.

There is a hole on the casing for a noise cancelling microphone.

There is an infrared proximity sensor next to the ear cushion, which is responsible for automatically pausing music when either earpiece is removed from the ear.

On the end there is a touch panel, with which you can control some functions, more in the manual.

From the case they charge in 20-30 minutes, but to recharge it you need a little more than 1.5 hours.

How to charge the wireless device Xiaomi Redmi AirDots

In order to understand how to charge your AirDots properly, you need to understand its charging indication system. Percentage of current charge of the headphones can be seen on the screen of your smartphone, but the amount of charge of the box (box) to understand is very problematic.

To charge the Xiaomi headphones you need to insert them into the charging box. It is impossible to mix up the left and right earphones, because they simply can not be inserted in the wrong places.

You only need to plug the micro USB charging cable with one end into the charging box and the other end into a USB port on your charger, PC or tablet.

During charging, both the box and the headphones light up red.

When the case is charged, it will stop glowing red and you can turn it off. The average charging time for Xiaomi Redmi AirDots is between 1.5-2 hours.

On some models of headphones, the color of the indicator will change from red to white when the case is charging.

How and How Much to Charge the Headphones

As a power source in each of the wireless headphones Xiaomi Redmi AirDots installed lithium battery capacity of 40 mAh, which is enough for 4 hours of continuous operation in the mode of talking / listening to music and 150 hours in standby mode.

Useful. Continuous operation time is indicated for simultaneous operation of two headphones. If you use only one, the energy will be enough for 5 hours of listening to music and talking, because the devices are constantly in sync with each other while working in paired mode.

To charge Xiaomi Redmi Airdots possible using the accompanying charging station, which also acts as a case or storage case.

But before we talk about charging the headset, it should be noted that the charging station itself has its own rechargeable battery, which means that it is able to work in a povibank mode. to charge the headphones autonomously, without connecting to an external power source. The built-in 300 mAh battery in the case is enough for 3 charges of a set of headphones.

To charge the battery, just place the earpiece in one of the recesses of the station. In this case, the contacts of the earpiece will connect to the contacts of the charging dock, and the headset itself will be held in place by a magnet.

Important. You don’t need to exert any force when inserting the headset into the charging dock. If the headset does not “fit” in place, then it is not its place. the sockets for the right and left earphones are different.

The charging process is indicated by the LED indicator, which will glow red.

As soon as the headset battery is charged, the color of the indicator changes to white, it is ready for use. If we leave the gadget in the charging station, after one minute the indication turns off. the device is charged and waiting to be used. Usually it takes 1.5 hours to fully charge the battery.

Remarkably, the case supports a pass-through charge function. it can charge itself and at the same time charge the headphones.

It’s all clear with charging, but how do you see the battery charge of a headset while it’s in use?? You can do this with the mobile device to which the headset is connected. But if we do not keep track of these indicators, then at a critical level of battery charge the headset will start periodically issuing a voice message, warning that the battery power is running out.

How to connect Mi True Wireless Earphones

The new development is delivered in a miniature box from the company: the device itself is drawn on the front, the sides shows the key differences of new items, and on the back side are written specifications, parameters of the device, as required by the standards of production. The whole description is in Chinese. How to connect Mi True Wireless Earphones read the article below.

On the sides of the headphones are holes, which suppress the noise from the outside, on top, at first unnoticeable, because of the layer of plastic, white LED-indicator. At the bottom you can see a few contacts, they are needed to charge the headphones and connect the main microphone.

How TWS wireless headphones are built: results of Xiaomi Redmi AirDots autopsy

This article appeared because of sad event: one of TWS-headphones Xiaomi Redmi AirDots (left) was not only dropped, but also crushed! This is nothing, in life and not meet such things.

But every cloud has a silver lining: there is an opportunity to examine thoroughly the inner workings of the headphones TWS (True Wireless Stereo), which will be presented in the following narration.

This is how the Xiaomi Redmi AirDots headphones (aka Mi True Wireless Earbuds Basic) looked when alive (without the case):

Going forward I would say that the part of the earbuds that is facing the reader in the picture is not just a back cover, but a cover with a button (it will be dismantled too).

Disassembly TWS headphones Xiaomi Redmi AirDots

Now let’s look at what the headphone turned into after the event described above.

Here and below all pictures are clickable.

Here you can see the motherboard, the battery and the part of the case that holds the headphone speaker.

Examination of the halves of the case showed that they were joined without glue, only with clips. So with enough care they can be disconnected without damage and without extreme effort.

The markings on the battery are not very clear; but you can read that the capacity is 0.16 watt hours (Wh), which is about the same (in mAh) as the officially stated 40 mAh. This is not much, but the dimensions are extremely limited, you can not stretch!

Now let’s examine the main part of the headphones: the motherboard.

This is what it looks like with the side facing the back cover (t.е. outward from the user):

In the center there is a single mechanical button, which is used to control the headphone. If you press the pin in the center of the button, you hear a characteristic and distinctive click of the button. The stroke of the button is small, about 0.5 mm.

Many other TWS headphones use touch controls, but the mechanical one has its advantage: there are no false positives.

Above the button there are two LEDs. The white-transparent LED is actually red; and the yellow one is actually white.

To the right of the button is a 40 MHz quartz oscillator.

The most puzzling part on this side of the board is the rectangular black and white part at the bottom of the board.

It is also to the same and volumetric (has a noticeable height), let’s look at this detail from the side:

I can guess that this is such a 3D antenna for the Bluetooth channel. But I am not more than 10% sure of my assumption; there are just no other assumptions at all.

Now let’s look at the front of the motherboard:

The central part of the whole device is the RTL8763BFR chip (by Realtek). The chip supports Bluetooth 5.0; AptX protocol is not supported (many people are interested in it, but it is not and cannot be here). A detailed description of the chip is here (PDF. jazz.)

Beside all the other connectors on the board, there are two miniature coil elements (inductors). One of them (with a yellow dot) is on the right side of the main chip and the other one under the yellow wire.

The microphone is behind the matte plastic on top of the board.

Now let’s look at the rest of the circuit.

Let’s take off the silicone ear cushion and look at the half of the case with the speaker and charging contacts:

A very fine mesh is placed in front of the speaker to protect against dirt. Dirt won’t get in!

Now let’s take the speaker apart completely and look at the voice coil and magnet system.

According to the official specifications, the diameter of the sound emitter is 7.2 mm.

At the bottom of the magnet system you can see a small hole, probably made to improve the bass reproduction.

The magnetic system is small but strong. It holds firmly to the wall of the refrigerator. 🙂

Now let’s look at the back side of the case half with the contact pads:

You can see the board itself with the pads and a mystery detail (since it isn’t connected to anything): two shiny strips on the sides of the board with the pads. These are miniature magnets, which help the earphone to stay in the case and thus prevent an abnormal interruption of the charging process.

And at last let’s take apart into parts the other half of the case, where the mechanical button is fixed:

On the right here is the actual second half of the case, and on the left is the button which is inserted into this half of the case and is held in it by snaps.

At the bottom of the case you can see a thin hole through which the light from the LEDs passes.

Woof woof woof So much for the mechanicals. There remains the philosophical part (conclusion). 🙂

First. a few words about TWS headphones, which happened to be the heroes of this article. Xiaomi Redmi AirDots.

These are some of the most inexpensive TWS headphones on the market.

They can be put in the “medium range” class with a good price-quality ratio. To study public opinion about these headphones it is useful to read the reviews of owners on the following links on Yandex.Market.

These relatively inexpensive headphones are good if you’re not sure if you need TWS headphones or not yet.

If you like them, you can move on to more expensive models.

TWS headphones are “on trend” right now, but they also have their own specific problems.

As an example, it is possible to note, for example, low autonomy in comparison with “usual” Bluetooth-headphones; as well as higher probability to lose one of the headphones. In addition, some users find them simply uncomfortable (taste is a delicate matter).

Average. but on Yandex service.Market can be found and points of sale with a lower price.

In addition, there is their modification Xiaomi Redmi AirDots S, which probably differs only in software (t.е. firmware). The price is about the same; you can check on Yandex.Market.

You can try to find on the Chinese sites, such as this seller on aliekskspress.

Another option. to use the search on aliekspress, but there are nuances.

Firstly, in Russian stores the for these headphones are quite competitive with Chinese; secondly, it is highly desirable to choose headphones with a global version (rather than Chinese); and thirdly, you need to watch out for counterfeit.

Xiaomi Air Mi True Wireless review. When size matters

In the fall of 2018, Xiaomi decided to squeeze Apple into the wireless headphone market a bit and announced its first TWS headphones, the Xiaomi AirDots (detailed review).

Despite the very good sound quality, these headphones had a number of drawbacks, the main one being the very principle of their operation. The phone was connected to only one earphone, and then the second one was connected to this earphone. So, in addition to a stable connection between the headphone and the smartphone, it was necessary to keep the connection between the headphones themselves. All this led to constant problems with the occasional disconnection of one of the headphones.

The company made the right conclusions and released a new version of the device called Xiaomi Air Mi True Wireless Earphones, popularly nicknamed simply AriDots Pro.

In this review, we will take apart the Air Mi True Wireless in detail and see if the new version turned out better than the previous one.

Design and convenience. Or XL-sized earphones

In a small box we are greeted with a charging case, a set of interchangeable ear cushions and a small USB Type-C charging cable:

And the first thing that catches your eye is the size of the device. The case has an angular shape that allows you to conveniently put it on any surface, but it also prevents you from comfortably hiding it in the s of tight clothing.

If you compare the Air Mi True Wireless case to the Airpods’ reference case for comfort, the former is almost twice as big:

charge, true, wireless, headphones

In the back of jeans case looks like this (pictured left Xiaomi, pictured right Apple):

The lid of the case is fixed with magnets, but if you put the case in your with the lid down, it can open when you take it out.

The quality of materials and workmanship is excellent. The case is made of thick matte plastic. On the front side there is an LED charge indicator. On the right side is a button to put the headphones in pairing mode and to reset them to factory settings. USB Type-C connector for charging is on the bottom edge:

So what made Xiaomi make the case so big? It would be logical to assume that the company sacrificed design and ergonomics in favor of functionality, placing inside the case, say, a large battery and wireless charging coil.

But unfortunately this is not the case. There’s no wireless charging, and the built-in battery capacity is 410 mAh. The battery is almost half the size of the Apple Airpods case, with a capacity of 400 mAh.

From the case, let’s move on to the design of the Mi True Wireless. These are vacuum headphones that look like Apple Airpods. Each headphone is equipped with a touch panel, LED charge indicator, two microphones and a proximity sensor:

No complaints about materials and build quality. The headphones are made of the same matte plastic as the case. There is moisture protection to IPX4 standard, that is, the headphones are not affected by light rain or sweat. But it is impossible to take a shower, let alone to swim in Mi True Wireless Earphones.

The touch pads look very nice, they are the main design element of the headphones:

Xiaomi Mi True Wireless is noticeably larger than the same Apple Airpods, especially the headphone sticks:

And while Apple has placed batteries in the Airpods sticks, the Xiaomi Mi True Wireless has nothing but a microphone and board. All the main components (speaker, battery, sensors) are placed inside the headphones themselves:

The headphones are held in the case by magnets. And if they are inserted there without any problems, then to get them back out of the case is very uncomfortable simply there is nothing to grasp, the headphones slip out of your fingers.

The headphones come with 4 pairs of interchangeable ear cushions. If you want to replace the ear cushions with your own, note their inner diameter, it is 4 mm. The grids that protect the sound path of the headphones are not made of metal, and therefore can deteriorate over time.

In general, the appearance and quality of Xiaomi Air Mi True Wireless is noticeably better than the previous model AirDots. The only problem with the design is the size of both the case and the headphones themselves.

Mi True Wireless Earphones sound quality

It is almost impossible to talk about the sound quality objectively, as the sound perception depends on the physiological characteristics of each person. And when it comes to the sound of vacuum headphones, then the task becomes even more difficult. Both the right fit in your ears and the right ear cushions are important in this case.

In reviews and forums you can find directly opposite opinions about the sound quality of the Air Mi True Wireless. Therefore, it is necessary to understand this issue in more detail. And we start with the bass.

The bass in the headphones is there and it is more than enough. Why then some people claim it is completely absent? This is where the fit and ear cushions play a key role. If the ear cushions do not sit tight in your ears and do not completely seal the ear canal, you will have bass problems.

When testing the different ear cushions (not just the original set), there was one interesting feature of these headphones. May be it’s because of their shape or the length of sound tube, but sometimes I had the feeling that the headphones don’t go deep into the ear canal. It greatly affected the quality and quantity of bass. A properly fitted, larger earphone cushion changes the situation drastically.

Therefore, do not jump to conclusions until you are sure that you are listening to the headphones correctly. This problem is especially present in many users on YouTube, who do on-camera unpacking and talking about their first impressions. Some people get the headphones right out of the box, others have to find the right ear cushions and the right fit.

In general the sound is quite smooth. The detail in the mid and high frequencies is not bad. They sound a lot like Apple Airpods. Separately, I would like to mention the presence of the scene. The sound is quite voluminous and is not felt inside the head.

Tested the headphones in conjunction with a smartphone Sony Xperia 1. The volume is very good, physical discomfort occurs already at 80% volume. It is also important to note the support for AAC codec. But on some smartphones Mi True Wireless Earphones works only by SBC and you can not select another codec. What does this depend on it is hard to say.

Active (ANC) and passive noise reduction

Xioami Air Mi True Wireless, as mentioned above, are vacuum headphones, which means that there is already a passive noise cancelling. The ear cushions close the ear canal, creating a vacuum effect. The quality of sound isolation is average. If you listen to music not very loud, you can hear the sounds of the street and even more so the subway. If you set the volume to 70% or higher you won’t hear the surrounding sounds.

But in addition to the passive noise cancelling, this is the first time we encounter active noise cancelling in TWS headphones. If you press and hold the touchpad of one of the headphones for 3 seconds, ANC (Active Noise Cancelling) is activated.

The microphones on the Mi True Wireless pick up external noise, and then the speakers play back that signal in out-of-phase. That is, it creates a mirror wave, which dampens the surrounding sound (read about noise cancellation in our new article in more detail and in clear language):

If you’ve ever heard this technology work on full-size Sony or Bose headphones, then the Mi True Wireless will disappoint you greatly. There is nothing of the kind here.

When ANC is turned on, all ambient noise seems to lose low frequencies. For example, the sound of a truck engine becomes less deep, and more of a buzzing sound. There’s also a little bit of sound localization lost. With the noise modulator off you can clearly identify the position of the sound source, but if you turn on the ANC and this position becomes blurred, it becomes more difficult to identify exactly where the sound is coming from.

charge, true, wireless, headphones

In general, the feature is there and it even works a little bit, but not at all as interesting and high-quality as on full-size headphones from famous manufacturers or TWS-headphones Apple Airpods Pro and Sony WF-1000XM3. If you remove this feature, you won’t notice much difference. In other words, it’s definitely not worth buying the Mi True Wireless just because of the active noise cancellation.

Mi True Wireless Earphones functionality

All music control is through touchpads. It’s important to note that it’s the sensors used here, not the accelerometer as on other earbuds, which actually respond to taps.

  • Double tap either earphone to answer an incoming call
  • Double-tapping the right earpiece play/pause
  • Double-tapping the left earpiece calls the voice assistant
  • Touch any earphone and hold for 3 seconds to turn on/off the active noise cancelling

Unfortunately, it is not possible to adjust the volume or switch tracks with the headphones. Alternatively, you can use the head assistant for this. That is, touch the left earpiece twice and say the command next track.

See also  How to charge Xiaomi AirDots headphones

Also each earphone is equipped with an IR sensor. Music automatically pauses if you take the earphone out of your ear.

As for the range of action, the manufacturer claims 10 meters. In the house, the connection holds great. The phone can be left in the same room and the headphones will have no problem keeping in touch even through the wall.

There is no official Mi True Wireless app for smartphone. Accordingly, it is not possible to update the firmware or configure the gestures yourself.

There is also a slight limitation when using only one headphone. If you insert only the right earpiece, then you can double-tap to stop the music, but calling the voice assistant is not available. It is logical to assume that using only the left earpiece, double-tapping will trigger the voice assistant and that the pause/playback function will not be available. However, this is not the case. The left earpiece will also pause the music and there is no way to call the voice assistant.


Of course, Mi True Wireless can also be used as a headset. Each earphone has two microphones for basic and additional noise cancelling. But there’s nothing exclusive about the voice quality. What’s more, you can often hear the interlocutor’s static and voice distortion. The quality of communication on the phone is noticeably better than using headphones. On the other hand, you will hear the other party fine.

As with all models, you can use one earphone (the one that you took out of the case first and will work as a headset).

Simultaneous connection to two smartphones

Mi True Wireless Earphones have a unique possibility to link each earphone with its own smartphone.

To do this, you need to put only one earphone in the case, press the side button of the case for 2 seconds and connect that earphone to the first smartphone. Then we take this earphone out of the case and put the other one in, press the button again for 2 seconds and connect it to the second smartphone. Now you can use them at the same time with different phones.

If the headphones don’t connect or don’t work correctly, you can reset them to factory settings. To do this, you need to insert them into the case and press the side button for 10-15 seconds.

Misalignment of sound

When watching video the sound lags a little behind the image. The difference is a few hundredths of a second and does not really spoil the viewing experience. But it is impossible to play games, the lag is too critical. However, this is not a problem of Mi True Wireless, but TWS-headphones as such.

Autonomy Xiaomi Air Mi True Wireless

From a full charge, the headphones work for about 3 hours at volume

70%. They are discharged independently of each other, and it often happens that one earphone has already disconnected, and the other is still playing for 10-20 minutes.

The battery capacity of the case will be enough to charge the headphones 3 times, thereby increasing the total sound time of the headphones to 10 hours.

Charging time of the case is 1 hour.

It is impossible to know the exact charge level of the case. When the side button is pressed, the light on the case either lights steadily for 5 seconds or blinks. In the first case, the charge is sufficient, in the second case, it is not. What exactly is meant by enough and not enough Xiaomi does not specify.

the charge of the headphones is determined in the same way. When you open the lid of the case, the indicators on the headphones either light steadily for 5 seconds or blink. unlike battery case you can see exact percentage of charge of headphones on your smartphone.

Air Mi True Wireless Earphones review. Conclusion

Mi True Wireless has only one major disadvantage, and that is the size of the headphones. They are noticeably larger than similar products from Samsung, Honor, Huawei, Xiaomi and Apple.

And the main thing is that such a big size is not due to any additional features, the company just could not (or did not want) to make a compact enclosure at the level of competitors.

If you are not confused by size and you understand what is vacuum headphones Xiaomi Air Mi True Wireless will be a good choice for its price.

The closest competitor to these headphones Huawei Freebuds Lite, a review of which you can also read on our website.

Xiaomi Mi True Wireless Earphones 2 Basic headphones review

The headphones I’m reviewing today are still out in the summer of 2020. And we need to clarify a couple of points, these very headphones (reviewed) are a cheaper version of the Mi True Wireless Earphones 2, which were also announced in 2020, but only earlier. And also the gadget that we will talk about is known under another name. Mi AirDots 2 SE. Actually now we can proceed to the review.

The headphones come in a blue cardboard packaging. Since this is the international version here you can see the description in all the “popular” languages of the world. On the front side you can see a picture of the headphones themselves, the company logo and the model name.

On the back of the box, as well as on the sides (right and left) are the main technical specifications.

I wanted to write that the packaging is easy to open, but no, the manufacturers have all very tightly “shoved”. Charging case and headphones inside the box are separate, so there is no excesses.

In addition to the headphones and the case the manufacturers put inside the package:


The charging case has a symmetrical form factor and is made of high quality matte plastic.

If we compare the size of the headphones with Xiaomi Redmi AirDots 2, they are almost identical. On the front side of the body is a LED, and on the back of the connector for charging.

The headphones themselves inside the case are fixed firmly and enjoy the fact that they can be removed without any problems. The cover is fixed magnetically in closed position.

Many people, like me, did not like the size of the headphones, or rather their thick “legs”. They are very striking to the eye. I am sure that in small women’s ears, they will not look very harmonious.

The headphones are equipped with touch control, which is located on the top of the headphones. On the bottom there is a white moonlight LED, which periodically blinks while in use. In addition to it on each “leg” are two microphone and magnetic connectors for charging.

The headphones can not be called weighty, I would even say that they are lightweight and almost do not feel in the ear. I personally have them firmly fixed and do not press on the ear. However, they do not isolate ambient sounds.

Assembly and materials must be recognized that are made at a high level. But, unfortunately, there is no protection against moisture and sweat, so the headphones are not suitable for training.

The control

As I said earlier the headphones have touch controls. A double tap on the right earpiece pauses the music, or vice versa begins to play it. Double tap the left earpiece to bring up the voice assistant. You can receive (and reset) a call with a double tap on either earpiece.

The touch area, unfortunately, is not highlighted in any way. So to miss is not a problem. Indeed, sometimes it is easier to take out the headphone to pause the music. Also of the disadvantages, I will note that you can not use the headphones to switch tracks, but given this implementation of the control, it would be a real challenge. It is not possible to adjust the volume.

There are 14.2 mm diameter dynamic drivers inside the headphones. The signal is transmitted via SBC/AAC codecs, so it makes no sense to listen to FLAC or other lossless audio formats. However, most streaming services do not offer such a feature, which means that the headphones will satisfy the needs of their users.

The headphones give you deep bass that is audible even at low volume. For earmolds, this is quite unusual. The gadget doesn’t block your ears, so the low-frequency hum doesn’t make you tired at all.

Voices sound natural, but fast instrumental parts lose audibility. These headphones are understandably not geared for aggressive music. It’s best to listen to quiet genres. For example, SayWeCanFly indie pop plays very well. For background listening to this kind of music or podcasts the headphones are perfect.

High frequencies are relegated to the background, so their harshness and simplicity is not as much of a throwback. It is very easy to get used to this pitch, after which the tone is perceived even. Given the price of the device, you should not expect anything better.


The battery capacity in the charging case is 410 mAh, which is pretty good. In total, from one full charge headphones with fully charged case will last about 16-20 hours.

The headphones themselves inside the case will charge to a “full tank” in about 60 minutes, and the charging case in

90 minutes. All of these indicators give or take the same amount as the competitors, noticeably different only headphones on Qualcomm chips, but they are usually a lot more expensive.

To sum it up, before you buy Xiaomi Mi True Wireless Earphones 2 Basic, you should definitely try them on first. It is very likely that they will not fit you in size and you will be very upset.

If their size does not scare and the complex control “do not care”, the headphones will please you. But from the minuses also note the lack of protection against water.
