Xiaomi AirDots wireless headphones (including Redmi AirDots, Mi True Wireless Earbuds and their modifications) have become some of the most popular gadgets due to the combination of price and quality. However, many users face a typical problem: after buying or resetting, only one earphone is connected, and the second one remains silent, the reason lies in the violation of synchronization between the right and left modules - and today we will discuss how to fix this.
In this article, you will find step-by-step instructions for connecting both headphones to Android and iOS smartphones, as well as solving common errors, from the lack of sound in one of the headphones to problems with automatic pairing. Particular attention will be paid to hidden functions of the headphones (for example, Dual Mode), which the manufacturer does not always advertise, but can save the situation.
If you've tried standard methods before and nothing has worked, don't rush to bring your headphones to the service. 90% of the time, the problem is solved software-based, without any interference with the hardware, and the main thing is to follow the algorithm and not miss the steps.
Why is there only one Xiaomi AirDots headphone?
Before we get to the instructions, itβs important to understand the root of the problem. Xiaomi AirDots headphones work on the principle of βlead-followβ: the right earphone (usually marked as R) is the main one and synchronizes with the phone, and the left (L) connects to the right one using Bluetooth Low Energy (BLE) protocol. If the communication between them is broken, you hear sound only in one device.
The main causes of failure:
- π Battery discharge in one of the headphones (even if the indicator is on, the charge can be critically low).
- π± A pairing error in the phone (for example, the headphones are saved as two separate devices).
- π Resetting the settings of one of the headphones (accidental press of a button or software failure).
- π οΈ Hardware malfunction (damage to contacts in the case or microphone in the headphone).
- π² Outdated firmware of headphones or phone (relevant for models older than 2020).
A critical feature of Xiaomi AirDots is that if the right earphone is down to 0%, the left earphone automatically stops responding to the connection, even if it is charged, and this is protection against incorrect synchronization.
Preparing headphones for connection: 5 mandatory steps
Before syncing both earbuds, do some pre-production, which will eliminate most software errors:
- Charge headphones and case. Connect the case to the network for 15-20 minutes, even if the indicator is on. Make sure that both earphones are physically charged (they should flash red lights when placed in the case).
- Delete old devices. On your phone, go to Settings β Bluetooth and delete any records with Mi True Wireless, Redmi AirDots or the like.
- Reset the headphones. Remove both earphones from the case and press the control button 5 times in a row (press interval - 1 second). After reset, the indicators should flash red and white.
- Check physical contacts. Clean metal contacts on headphones and in the case with a cotton swab soaked in alcohol. Contact oxidation is a common cause of charging problems.
- Update your phone software. On Android, check the Bluetooth stack version in Settings β About Phone β MIUI (for Xiaomi). On iOS, upgrade to the latest version via Settings β Basic β Software Update.
β οΈ Warning: If the headphones don't flash red and white after reset, but only white, this is a sign of hardware failure. Try plugging them in separately (see section below.

Instructions: how to connect both headphones Xiaomi AirDots to Android
Algorithm for Android smartphones (including Xiaomi, Samsung, Realme, etc.):
- Activate pairing mode. Pull both earbuds out of the case. Press and hold the buttons on both earbuds for 10 seconds until the indicators start flashing red and white (search mode).
- Connect your right earphone. On your phone, turn on Bluetooth and find a device called the Mi True Wireless EBs. Basic_R (Or something like that. You plug in to it. You wait for the beep in your right earphone.
Wait for automatic synchronization.
- After 5-10 seconds, the left earphone should connect to the right earphone automatically, and you will hear a second beep.
- In the list of Bluetooth devices will be a record of Mi True Wireless EBs Basic_Stereo (or Redmi AirDots_Stereo).
If the left earphone is not connected:
- π Reboot your phone and repeat the steps.
- π± Remove the right earphone from the Bluetooth list and connect again.
- π Check the charge of the left earphone β if it is discharged, the case may not charge it due to damaged contacts.

On some Xiaomi models (for example, Redmi AirDots 3 Pro) for forced synchronization, you need to press the button on the right earphone 3 times after connecting to the phone.
Connection Xiaomi AirDots to iPhone (iOS): features and nuances
The iPhone algorithm is similar, but there are key differences:
- Headphone reset. As with Android, reset your headphones with a 5-fold push of the buttons. On iOS, it's important to wait until the indicators start flashing quickly (this is a sign of readiness to pair).
- Connect through settings. Go to settings. β In the list, find Mi True Wireless EBs. Basic_R Do not close the Bluetooth screen until you hear the signal in both headphones (on iOS, synchronization can take up to two hours). 20 seconds).
Stereo check.

β οΈ Attention: On iOS 15 and later, there may be a bug where the headphones connect as Phone Audio (mono mode). To fix: Forget the device in Bluetooth settings. Turn off and turn on Bluetooth on your iPhone. Reconnect the headphones after waiting for a double beep.

On iPhone, Xiaomi AirDots can work in mono mode if the phone has previously connected to a single earphone (for example, for calls).Always delete old records before reconnecting.
Manual synchronization of headphones: if the automatic connection does not work
If after all the manipulations left earphone stubbornly does not connect, try forced synchronization:
- Turn off the right earphone from your phone. Forget it in the Bluetooth settings.
- Place both headphones in the case and close the lid for 10 seconds.
- Pull out the left earpiece. Press the button 4 times (with intervals of 1 second) The indicator should flash blue, which means that the earpiece is ready for manual synchronization.

Alternative method (for models with Dual Mode):
- π§ Connect the right earphone to the phone.
- π Turn on the music and pause it.
- π Press the right earphone 3 times β the voice signal βDual Modeβ should sound".

What if the headphones are defined as two separate devices?
Table: Common mistakes and their solutions
| Problem. | Possible cause | Decision |
|---|---|---|
| Left earphone not plugging in | Unloaded or unsynchronized with the right | Charge the case for 30 minutes, reset the headphones, plug the right first. |
| The sound is only in one headphone. | Mono mode (on iOS) or synchronization failure | On iOS: forget your device and reconnect. On Android: turn Bluetooth on/off |
| Headphones are connected as separate devices | Firmware or Bluetooth stack error | Remove both devices, reset your headphones, connect your right first. |
| Indicators do not blink after resetting | Hardware malfunction or discharge | Check the contacts in the case, charge 1-2 hours, repeat the reset |
| The sound is interrupted or distorted | Interference from other devices or outdated firmware | Update your phone, disable other Bluetooth devices, reconnect your headphones |
Hardware problems: when to carry in the service
If all software methods have been tried, but the headphones still don't work properly, there may be physical malfunctions.
- π΄ The indicator does not burn at all - the battery or power board is damaged.
- π There is a sound, but very quiet or with interference β a problem with the speaker or microphone.
- π The headphone does not charge in the case - oxidized or broken contacts.
- πΆ Permanent communication breaks β the Bluetooth antenna is faulty.
What you can do on your own:
- π οΈ Disassemble the case and clean the contacts with alcohol (carefully, without pressing!).
- π Check if the battery in the headphone is swelling (visually noticeable by the deformation of the body).
- π§ Try connecting your headphones to another phone β if the problem is repeated, itβs their fault.
β οΈ Warning: If the headphones stop working after falling or getting moisture, do not dry them with a hair dryer or on a battery - this will accelerate the corrosion of the contacts.
