>>>FAQ: Answers to frequently asked questions and solving problems - read first<<<
Please read all three spoilers before asking a question in the topic. Most likely, the answer is there.
Questions before purchase
Important!
1.Headphones can work very poorly with some models of smartphones: the sound is constantly interrupted.
2.These andlike almost all other Bluetooth headphones, even expensive for $ 100-300 unsuitable for games on Android, for example, in PUBG: a very large sound delay.
Learn more about all this, see the spoiler "Solving Problems." Although, the newS-version of these headphonesIt reduces the delay to 0.5 with a PUBG.
----------------------------------

Which seller is better to buy?
Everything regarding prices, delivery and sellers is discussed in a separate topic.Purchase. This topic is only for discussion of the headphones themselves.

How do I know if I have the original?
Fakes exist and are very similar to the original.Hereexamples, attributes and their sellers are collected. You can not check on the Xiaomi website by code.How does forgery

What are the differences between Chinese and global versions?
- globallikeis always on the case "MI", the Chinese may be "MI" or "Redmi", that will fall
- different official name: "Redmi AirDots" and "Mi True Wireless Earbuds Basic", respectively, Bluetooth-device names, too, such
- the language of the inscriptions on the back of the box and instructions: on the Chinese all the Chinese on the global there are inscriptions in Russian,instructionalso
Other technical differencesnot, the sound is the same.
The price on the global higher because, presumably, it is higher in the purchase of Xiaomi.

What is the difference between Xiaomi Mi True Wireless Earbuds (ZBW4420GL) and Xiaomi Mi True Wireless EarbudsBasic(ZBW4480GL)
The first - a global version of a very different, older model: they are more white, with touch-sensitive buttons and AAC codec. discussed inseparate topic

What is the sound quality?
Obviously, this is a very subjective and individual question.
Most agree that the sound is very good considering the low price (and you do not forget about it).
Also wrote a lot of treble. But you can get used to this.
Or in EEPROM / player equalizer raise and lower the low frequency high (last column).
If there is no equalizer (so, on MIUI, it does not work for BT headphones), try the applicationEqualizer fxorEqualizer pieif you have android 9 and up.
Do not forget to include the global mode settings (not available for Pie), ie the sound change even on YouTube.
For iPhone / iPad useHS Player, It does have an equalizer.
And there were also reports that changing ear cushions / other fastening in the earLittlechange sound, experiment.
Alsowrotethat the sound can differ even between two pairs, i.e. what will fall.
Although, from the codecs there is only SBC, it can be raised to the level of the notorious AptX:more

Is there any background noise?
Yes, a little. Visible only on quiet tracks or if you turn off the music. After 5-10 seconds is lost due to the lack of "good signal". can be reducedSo

Are they loud?
Yes. At 100% volume to listen uncomfortable. And while the sound is significantly distorted.
The volume can be increased even more in the equalizer of the player / firmware / third-party equalizer (see above), evenly raising all frequencies.
Important: the volume level is different for different devices.

What is their insulation?
Good, in the subway, you can listen to. Of course, provided a suitable size and dense ambyushury Fitting in the ears. Please be careful on the streets.

Do they fall out of ears?
No, because they are mounted in the ear canal.
You can jump, run, tilt and shake your head. Therefore, headphones are suitable for running or gym.
But the anatomy of the ears is different for everyone. Even the left and right ear may be different. If anything, use larger ear pads.

Are they strongly felt in the ear?
The first time may be unusual, but then they are invisible. The more they weigh only 4 grams each.

Davit whether in your ear while you press the button? Is it loud clicks?
If the earphone is pressed tightly to the ear, then there is no discomfort from pressing, little effort is needed.
But sometimes it is temporarily pressed deeper than distorting the sound. There may be differences depending on the anatomy of your ears. The solution isbypass puncture
The click is over, heard loudly. In general, the button can be used.

Is it waterproof?
Splash protection only. But, as usual, it is better not to risk it. Important: the case is not protected.
The manufacturer claims class / degree of protection IPx4, which means:
"The device will not suffer when exposed to a large number of sprays directed from different sides (for example, rain, drops from the shower)"

Is there a sound delay?
There is no disturbing delay when playing music / movies / YouTube from a smartphone -test video
However, this may depend on the device used and even application, they are especially tunes the image delay to synchronize with sound.
In games (PUBG), the delay can be ~ 0.8 s and thus interfere very much. Nothing to do with it. More details in the "Problem Solving" spoiler.
Although, the newS-version of these headphonesIt reduces the delay to 0.5 with a PUBG when the game mode.
Also, usually with a computer a little delay in music there. In games, the contrary seems to be OK.
Remember that sound transmission via Bluetooth in any case creates a delay: with the SBC codec, it is 150-250 ms, plus 20-80 ms for buffering.

How long do they work on one charge?
Reported to 4 hours.
With the new battery (do not forget wear) - about 3:30 hours of music / talk on the volume of 40%. With movies / YouTube where there are fewer sounds can all 4.
If you use only one earphone, it will last for 6 hours of music at a volume of 40%. Plus stay another by the same amount.
A fully charged case exactly can recharge them an average of 3 times the duration of a single charge - 1:10 am.
Total charged if the headphones were previously treated for 14 hours without being connected to a power outlet.

How quickly does the phone discharge when using them?
itcomplex issue, considering the different capacities of the batteries and their wear. If the phone is not used, then the discharge is approximately 2-4% per hour.

The microphone is on both ears?
Yes.

What quality microphones?
Not good quality. Interlocutor sure to notice what you are talking on a headset, even in silence.
Noise heard around better than the voice. However, someone has no problems.
Possible causes: poor-quality microphone, its location in the body, cover the hole the tragus of the ear or due to noise reduction.
Hole enlargementdid not help
As a solution, you can remove the right earpiece and talking into his microphone. Turn it off (use the phone) can not.
The sound is a little better (less "bubnyavosti") if you use only the left earphone, ie when it is connected separately.

Whether there is noise reduction?
Noise reduction is claimedonly by speaking, not during music.
Its working principle is as simple as noise filtering, rather than using a second microphone. Turn off the impossible.

When talking, is there sound in both headphones?
Yes. By the way, only the right microphone is used.

Can I use only one earphone?
Yes. More details in the next spoiler.

nonewireless headset with Bluetooth does not transmit sound source, it is always compressed lossy codec.
In any case, only once is better pinch (FLAC), than again (MP3).

Are they suitable for cycling?
Positive reviews:1, 2, 3, 4, 5
But two users (1, 2) there are constant interrupts. The reason is unknown: marriage or incompatibility with the phone.
Remember, due to insulation to ride them on the road with the road is very dangerous.

My device only supports Bluetooth 1.2 / 2/3 / 4. Will they work?
Yes, there is backward compatibility.
They work even with the old "dialers". Double pressing the button on them causes voice dialing. Connection Code: 0000

Fakes exist and are very similar to the original.Hereexamples, attributes and their sellers are collected. You can not check on the Xiaomi website by code.How does forgery

How to switch tracks button on the headset?
Answer
It is not provided by the manufacturer, but there are such options.
Note: When listening to stereois impossibledo various actions by pressing the left and right headphones, because they transmit the same team.

1. Voice call pickup by double tap. Available only on Android, root not needed. It does not work on the Meizu, there use Dotdroid, see. Below.
You can do this in three ways:

Its advantages - you can change the action of a single press in addition to double, plus there will remain a call to the assistant.
May lead to a decrease in headphone volume, then you needreset

3. use the app Dream player ( a source ). The settings include "One-Touch mode" and set the desired action, supported by five strokes. Note that a few button presses in a row should be slow so as not to cause the assistant.

4. Quickly pressing the button on the right first, then the left. Works not on all firmwares and not with all the players. A source

5. Calls Voice Assistant by double-clicking the button ( Google Assistant , Siri , Alice ) and the team "switch to the previous track", "volume by 50 percent", "make it quieter" etc.: visually

I have written on the case "MI" / "Redmi". What is the difference between them?
No difference. To whom it comes across. So on the Chinese version, globallikethe whole "MI".
There was an assumption that only the owners with the inscription “MI” supposedly cracked the headphones and the case is quickly scratched, and the “Redmi” version has stronger plastic.
But it is disprovedsurvey results

I have a Chinese / global version. What is the difference between them?

3. Turn on Bluetooth on your smartphone, find the right earpiece in the list.(Redmi AirDots_R or Mi True Wireless EBs Basic_R)and connect to it
Note: the right earpiece is the main one, i.e. the sound first arrives at it and is further relayed to the left.

How to use headphones separately?
Remove only one earpiece from the case, perform the pairing as described above.
The ending of the device name will be different:_L- left_R- right.
Then you can remove the second and connect to another device.
Important: the left earpiece is always searched longer, for at first he tries to find the right one. Wait for slow flashing white after 20 seconds from switching on.
You can reduce this time if you include the earphone is the case. It is necessary to hold the button for 5 seconds (a source)
Listening to such a "mono-mode" adds about 2 hours of battery, i.e., up to 6 hours for 40% volume.

Can I use them with multiple devices at once?
Yes, but not at the same time (partialworkaround)
Pair with the right devices and unplug the headphones from one, and then connect them to another.

How to turn them on and off (restart)?
Simply put and remove from the case: the presence or absence of charging controls the power of the headphones.
Of course, for this to always work, the case must be charged.
Or you can hold the button on any earphone for 5 seconds, and the other will automatically turn off: the LEDs will be red for 2 seconds.
It is necessary to turn on each separately by holding the button for 2 seconds until the white display appears for 2 seconds.

It does not matter, they will still find each other.
The main thing is to extract between both is not more than 20 seconds have passed since then the left will stop searching and is available to connect to the phone.

How to improve the sound?
Experiment with the EQ of your firmware / player. Raise the low frequency and lower high (last column).

And any deviceberetas he needs, and therefore damage the "large number of amp" you can not.

sound is interrupted
(Sometimes / constantly on one / both headphones / when the phone is in your back pocket / backpack / cycling / only in the city, etc.)

Answer
Important! If, despite the tried options below, interrupts are still very frequent or permanent, then this is a marriage. The exact cause and solution are unknown.
Herean obvious example, one of the two pairs of "interrupted" on the street when connected to the same phone.
BUThereproblem solved installing breakaway parts on the board. Or is it a restudy akkumultorscreens the antenna

Interruptions happen to anyoneeven expensiveheadphones. Such an unreliable Bluetooth. Broadcasting is always a compromise.
This is due to the presence of obstacles, radio interference, also depends on the quality and location of the antenna in the phone.

Bluetooth works at 2.4 GHz, like most Wi-Fi rotors, and therefore very susceptible to interference from them.
The doubly loaded frequency spectrum aggravates the situation: transmitting first to the right earpiece and he to the left one.
Plus, because of the high frequency signal is easily absorbed by the body and obstacles between the phone and the headset.
Check it out: put the phone on a distance of a few meters and the well cover both ears with his hands.

HereIt is described how in large cities many people sound consistently interrupted at pedestrian crossings.
For Bluetooth, unlike Wi-Fi, is more dependent on the reflection of the signal from the surfaces around.
There is also a place with a very large quantitative interference, which interrupted any BT-headset.
For example, in St. Petersburg itmetro Pioneerand the intersection near the stationUlitsa DybenkoThere are interrupted even expensive AirPods.

In addition to interference from Wi-Fi, this may be incompatible with your phone.

Try with a different smartphone (preferably with Bluetooth 5.0) to eliminate headphone defects. Please unsubscribe to the topic if the problem is in your model.

You can try
- to update the phone's firmware
- go to the custom firmware
- turn off Wi-Fi
- switch router at 5 GHz
- Check the charge onbreakage of parts
- verifybattery status
- reset, But it seems to next turn

These andalmost any otherBluetooth headphones, even expensive for $ 100-300unsuitablefor games on Android, for example, in PUBG.
There's nothing you can not do so in the headphones in conjunction with Android, because it increases the natural delay of up to 0.8 seconds, which is impeding play.
This usually occurs because of thecomplicated processsound processing. The problem is in the operating system, not in the headphones.
Although, the newS-version of these headphonesIt reduces the delay to 0.5 with a PUBG when the game mode.
How they behave on the Apple-devices - is unknown. Delays in games is not only AirPods in conjunction with the iPhone / iPad, because they work together in a special way.
In the computer games like the delay allowed.

When listening through headphones, the Wi-Fi speed on the device drops
It seems like it happens with any wireless headphones, and also depends on the phone (the implementation of the transmitter and antenna).
Bluetooth operates at 2.4 GHz, as well as the majority of Wi-Fi points that cause conflict in the division of the frequency space.
The situation is aggravated by the fact that the headphones constantly transmit information and even doubly: first to the right earpiece, and he to the left one.
Total rate falls by 50-65%. Note that decreases proportionally from the source, e.g., from 80 to 40 or from 20 to 10.
Change channel Wi-Fi, of course, does not help. And on other devices too close speed can be reduced by 10-20 Mbps.
Here speed tests from a smartphone (Speedtest) When the music plays. The presence of a number of still some headphones (not TWS) diminishes more 5-15 Mbps.
Download / upload, Mbit / s:
- 75/85 - without headphones
- 45/60 - one
- 20/40 - two
Working solution: Use a router or other device in the "5 GHz only": not supported by all, also reduces the coverage area of ​​Wi-Fi.
Also try to translate router mode "only N".
You can stilldisable service NearbyMessagesService(Root is needed). On some phones it will eliminate a performance drop, but not solve the problem as a whole:example

One / both headphones in the case no longer glowing red
They just fully charged.
By the way, the left one charges faster due to the smaller load and therefore the discharge: after turning off the right one, there is still 40-50% left on it.

One earphone is constantly flashing red and white in the case, it does not work outside of it.
The fault is probablycharge controllerorthe battery itself. Trythis, this, this, thisandthis. Orreplace battery

One earphone is no longer on the phone (usually after a reset)
Since this is clearly a software problem, the earphone must somehow reboot the de-energized. The easiest way to put in the freezer, but it is harmful to the battery.
How long - depends on the current charge. Just check from time to time.Examplesuccessful decision.
Or tryclose contactsor disassemble, unhook and re-solder the wiring from the battery.

The headset always glows dim red and does not react to anything
There is no solution. Freezer to quickly discharge the battery, which means rebootingdid not helpMay disconnect the wiring from the battery will be more effective.

One earphone not included
Probably just a marriage fee. There is no solution. May helpbattery Replacement

One earphone included but will not emit any sounds
Probably,the posting was dropped

Headphones do not connect with each other, reset helps only until shutdown
Try to take them out of the case and place them as close as possible.

Headphones began to crack / a piece of plastic fell off
It seems to be used a low-quality or thin plastic. Or is it a constructive defect, because chips usually have latches. It happens at an average of 17% of the owners.
There was an assumption that this problem was allegedly only for owners with the inscription "MI", and the "Redmi" version has stronger plastic. But it is disprovedpoll
The assumption that the first batches also badoprovorgnuto poll
Possible solution: pour the problem area with epoxy resin orsuper glue with soda

Unpleasant, uneven sticking in the ears, laying, "vacuum", especially when pressing the buttons
Pierce the bypass

One earphone plays a quieter / else / rustles membrane / have crackling
Blow through, clean, warm uporpierce the bypass
If all else fails and one of the headphones still playing quieter / louder, you can useDub Music Player, in it you can change the balance of the channels.
Globally - inViPER4Android(need a root). Also for players, you canEqualizer pieif you have Android 9 and higher (root is not needed).
It defaults as possible since Android 10, the option toSettings>Special abilities>balance of sound

Both headphones have a very low
Typically, a software problem, it may happen very often, and the only solution - every time you doreset
it can also help: Turn adjustment "For Developers" (click to 8 timesSettings>About phone>Build numberorMIUI version) and activate the option thereDisable absolute volume level. This option has only 7 version of Android.
Optionfor owners of Samsung, disable playback on the two devices at the same time.
If all else fails, keep in mind the possible physical causes described in the question above.

- Prevents the background noise
- Quiet noise when navigating through the tape on YouTube and on websites

Two methods of noise reduction natural technical describedhere
The default YouTube enabled autoplay video tape / recommendations / trends can be disabled in the settings.
The sound in this case as it also plays, but at zero volume. It "activates" headphones, but there is no useful signal and technical noise becomes noticeable.
Same with advertising inserts or video on websites.
If the noise is very loud, or have only one ear, then this marriage.

Crackle, hiss, poor sound quality
On the Samsung due to a bug in their firmware may be degradation in sound quality when using wearable or fitness bracelet (Mi Band, etc.):more.
It is precisely to: Note 8, S8 +, A70, M31, J7 2016. Can help option off "Play. Sound 2 Device."

The sound is sometimes slowed down if "film stretches"
This occurs when a weak signal or noise. Put music on pause and wait for 10 seconds until the headphones fall asleep.

- Dumpty headset button
- Something knocks on the earpiece

Fixfor the button or is itbattery (addition)

Button pressed hard
Fix

- One or both earbuds do not charge in a case
- Pull out the headphones from the case, and they do not connect themselves
- Headphones are not turned off when I put them in the case
- Headphones are connected as in a case
- Charging is frequently interrupted in a case

The presence or absence of charge controls headphone power. That is, when they are turned off charging when it pereryvanii (extracting) - are included.
Most importantly: do not forget to remove the film from the headphone contacts and charge the case. More can interfere with the ear cups, even standard, try without them.
Check notwhether contacts have sunkand their purity, especially on headphones. Also, a case can be junk. See question below.
In unstable charging should helpthisorthis. Or stick to the inside of the cover film bubble or foam.

Case does not charge itself and does not charge headphones
Probably,the posting was droppedor needreplace battery

The case does not work without connecting the charger
Replace the battery

Right earpiece becomes shorter left
This is normal at all. After turning off the right on the left still remains 40-50% charge. Right becomes shorter because of the greater loads (retransmission).

Difficult to remove headphones from the case
This is temporary, later the plastic will be slightly wiped off and it will be noticeably easier to get out, even if you pry it from above.
In the meantime, to hook a finger over the lip of the recess to blow or shake of the hand, but be careful with the lid. or doSo, SoorSo

Each time you turn on, you need to pair again
Should helpreset

On hiatus indefinitely headphones begin to reconnect with each other
describedhere, A temporary solution -resetor switched off and on, there is a constant. Probably the marriage.
If it comes after it was recently updated phone firmware, then try to go back to previous versions.

When you turn off the screen smarftona interrupted or sound disappears
Decision

Headphones come to play in mono mode
Decision

- Both headphones are left or right and do not interconnect
- Headphones have different names from the Chinese and global versions and are not interconnected

Surprisingly, it also happens that they mixed something up in production, examples:1, 2. There is no solution to this.

How to clean the mesh from sulfur?
Instruction

no longer mesh
Try to replacethis

Wet the earpiece
Since they are only protected from splashing, immersion in water is very likely to result in breakage.
It is best to disassemble them immediately (snap-on mounting), disconnect the battery and rinse the board in alcohol.
But even if everything works without or with flushing, this does not mean that problems will not appear in the future.
Stories of partial and full self-recovery:1, 2, 3, 4, 5, 6, 7

Lost / broken case / earphone. It can be purchased separately?
On AliExpress may be rare offer headphones, but sometimes there is no earphone and headset from Xiaomi.
Although,right heresell and briefcase, and left and right (Chinese version).
By the way, maybe someone on sites with ads selling their used / have the same separately.
They sayThat the headset is the global versionwill beto work with the Chinese. Case is universal. To connect you need to doreset
Do not write the questions and suggestions in the subject, for the publication of personal ads for the purchase, sale or exchange of the devices is permitted only in the sectionFlea market

[B] Does case from * to * -version -version Suitable? / B]
Cases of all versions are mutually compatible.

How do I charge the headset without the briefcase?
Take any USB-charging by 5 Volt, "amps" and the presence of QuickCharge have no meaning).
Cut the connector, and a leanthe necessary wiring to the contacts, "Plus" is closer to the speaker.
The charging time from 0% - 1:10 am.

I don't hear well during the conversation
This is for many. Possible reasons: poor-quality microphone, its location in the case, covering the hole with the tragus of the ear or due to noise reduction.
Hole enlargementdid not help
As a solution, you can remove the right earpiece and talking into his microphone. Turn it off (use the phone) can not.
The sound is a little better (less "bubnyavosti") if you use only the left earphone, ie when it is connected separately.

Very high volume even at low
Try firstreset. Volume can be reduced in the equalizer player / flash / third party equalizer uniformly decreasing all frequencies.
Side:Equalizer fxorEqualizer pieIf you have an Android 9 and above. In his settings, you can turn global mode (not available for Pie), the sound will change everywhere.
For iPhone / iPad useHS Player, It does have an equalizer.

No sound when connected to PlayStation 3/4
The PS3: the settings to choose headphones for audio output:off instruction. Connection Code: 0000
PS4: by default it does not support any BT-headset. May earn through USB Bluetooth-dongle.

The button does not work to answer calls in the messengers (Telegram, Viber, WhatsApp, VKontakte)
She should not be, it can not be corrected.

Microphone does not work in voice recorder, camera, instant messengers
Please note, the sound quality is low, there's nothing to do, see. Question below.
- Recorder: will only workthis
- Video recording:decision
- Voice messages:decisionandstill
- Speaking of messengers: it seems it depends on the phone's firmware and it is not correct to

- The sound suddenly became very bad
- When connected to a PC is very low sound quality

This happens when an application on your smartphone or computer begins to use the microphone. For in the Bluetooth still remains outdated behavior.
When he was much slower to channel enough for sound transmission in both directions of its "quality" is reduced to 8 kHz instead of 44.
This is not correct, the only solution is to close the "Voice" app, for example, Discord or leave voice chat.
On Windows Audio settings can also bedo this way

- The radio does not work, asks to connect a headset
- In service tests, the headset is not recognized

For all this we needwiredheadphones or headset.

When connecting to a computer, it asks for a driver, where can I download it?
Headphones are a standard A2DP device; there is no special driver for them.
To solve the problem, reinstall, or install a new or even an old driver (stack) for your Bluetooth-adapter.

Double-click voice assistant call does not work
Fixif you MIUI.
To work Google Assistant may be required to include in itStill>Settings>Voice input>Allow a Bluetooth commands to unlock the device
For Meizu is no solution, because it is not implemented in their firmware.

I have MIUI and the equalizer is not available for BT headphones.
Alas, this is a feature of the firmware, it only works with wired ones. The application should workEqualizer fxorEqualizer pieif you have android 9 and up.
Do not forget to include the global mode settings (not available for Pie), ie the sound change even on YouTube.

Dangling the case cover

Please note that the ribbed edgesnot very high quality

Possible Solution

Sometimes completely sound disappears
Cm.here

Headphones do not work as a headset
Partial solution

Headphones do not connect automatically / no charge display
Just try off / on Bluetooth or restart your phone. Orreset the headphones.
Also in the Bluetooth settings next to the headphone press the GEAR / arrow and turn the "Calls" / "Profile HFP".

No sound an incoming call on the phone and / or headphones
This is clearly a problem in the firmware of the phone.
In the Bluetooth settings, click next to the headphone GEAR / arrow and turn off "the A2DP profile" / "Music". Of course, this will disable the music playback.

There are problems with the volume level (very loud / quiet / not adjustable) when used with another device
Enable the "For Developers" settings (press 8 times onSettings>About phone>Build numberorMIUI version) and activate the option thereDisable absolute volume level. This option has only 7 version of Android.

Earphone lost in the room
Important: without a connection, the headphones turn off after 5 minutes and then they can no longer be found on the signal.
If you listened to both and lost your left, then you won’t find it like that.
1. Disconnect from headphones through Settings
2. Install the applicationBluetooth Scanner, start, allow access to the location
3. Moving with the phone, watch the signal level fromRedmi AirDots_R / LorMi True Wireless EBs Basic_R / L: the smaller the number, the closer the earpiece
Alternatively, turn on the noisy track and set the volume to maximum. Note that this could theoretically damage the speakers.

- Case / earphones quickly discharged
- What is in them a battery?
- The earphone is warming up

Defective battery. Well, every battery eventually podverzhon loss of capacity.
Battery can be replaced: for casesuch(601235). Identical as in headphones (541112)not for salebut there is practicallyanalogue
By the way, in the cold, the batteries quickly lose their charge, so hide the headphones under the cap in the winter.
When heated, the earphone for your safety it is better to stop using it or even throw it away.

- Where can I see what's inside the device?
- How to disassemble it?

Herephotos of everything inside (longer wait for the download)
Special disassembly instructions None,herevideo andstillone. The headphones should be separated halves of the housing office knife or scalpel shooting with latches.
Case offers a very simple - to hook mediator inner half sides of the gap for the lid.
