Using a wireless headset in single-earphone mode is becoming increasingly popular among smartphone owners, convenient when you need to hear the environment, save battery power or just talk on the phone while the second headset is in the case. However, users often find that when you remove one True Wireless headphone Xiaomi it does not automatically connect or mate as part of a stereo pair, ignoring the single mode.
The problem can be both the software settings of the smartphone itself and the logic of the headset firmware. Modern models such as Redmi Buds or Mi AirDots have different algorithms for how to extract from the charging case. Understanding these nuances will allow you to quickly customize the device to your needs without unnecessary manipulation.
In this article, we will take a look at all the ways to connect a single headphone, from standard procedures to forced transfer to mono mode, and learn how to properly reset settings and avoid common errors that lead to channel dissynchronization.
Features of the work of TWS headsets Xiaomi in mono mode
True Wireless Stereo technology involves two headphones first connecting to each other, and then one of them acts as a wizard transmitting a signal to the phone. When you take out only one headphone, the device logic must switch. In Xiaomi models, a special chip is responsible for this, which determines the presence of a second channel.
If you take out your left earbud and your right earbud is still in the case, the system should recognize this as a transition to Mono mode. However, sometimes there is a desynchronization when the phone "sees" two devices or sees nothing, often because the previously stored profile in the memory of the smartphone contains data about the stereo pair.
💡
If the phone sees two identical devices with the name of your headset, delete both profiles before pairing again.
It is important to understand the difference between active noise cancellation and transparency mode, which can only work when using both channels. When you connect a single headphone, these functions often turn off automatically to save energy. Bluetooth protocol is rebuilt to one-way audio transmission.
⚠️ Attention: With prolonged use of one headphone, it discharges faster, as it takes on the entire load of signal processing and communication with the smartphone.
Preparation of the headset and smartphone for pairing
Before you try to connect the device, you need to make sure that both gadgets are ready to work. Charge the case and the headphones themselves to a level of at least 50%. Low charge can lead to unstable operation of the Bluetooth module and interruption of the connection during the setup process.
On your smartphone, clear the list of old connections. Go to Bluetooth settings, find your model (like Mi True Wireless Earbuds Basic 2) and click "Forget device" or "Delete." This is a critical step that many users ignore when trying to connect on top of their old profile.
☑️ Preparation for connection
It's also worth checking if the headset is connected to other nearby devices.If your Xiaomi headphones have previously been paired with a tablet or laptop, they may try to automatically connect to them, ignoring the phone.
Step-by-step: how to connect one headphone
There's a proven algorithm that allows you to force one earphone to activate. First, place both earbuds in a charging case and close the lid on the headphone. 5-10 This will allow the system to fully reboot and reset the current connection state.
Then, just take out one headphone (like the right one). Don't take out the second one. The smartphone screen should show a notification about the new device. If there is no automatic pop-up, go to the Bluetooth menu and search manually. The device name can appear as Redmi. AirDots_R or just with the "R".
Settings → Bluetooth → Search for new devices → Choosing a headphoneAfter successful pairing, check the sound. If the audio is only playing in one ear but the phone's settings show stereo, perhaps the balance is activated. Go to Settings → Sound and Vibration → Balance and make sure the slider is centered, even if the speaker is physically alone.
💡
The key to success is to remove only one headphone from the case, while the second is securely fixed inside and closed with a lid.
Configure balance and audio profiles in MIUI
Xiaomi's MIUI shell provides advanced audio management capabilities. Once you've connected one headphone, the system may not correctly determine the type of device. To fix this, open the Mi Earbuds or Xiaomi Earbuds app, if installed, where you can manually select your mode of use.
There are hidden features in the standard Android settings that underpin MIUI. Through engineering menus or special applications, you can-force the HSP/HFP (Hands-Free Profile) mode, which often works more stable for mono headphones than the A2DP profile designed for stereo.
| Parameter | Value for a single headphone | Where to find out. |
|---|---|---|
| Bluetooth Codec | SBC or AAC | Developer settings |
| Absolute volume | Included. | Bluetooth settings |
| Game mode | Off. | Xiaomi Earbuds app |
| Noise suppression | Auto/Off | Sensory management |
Note touch control. When you're using a single earpiece, some gestures may not work or work differently, like double tapping can switch tracks, but triple tapping can call up an assistant, who may sound quieter in mono mode.
Solving Channel Dissynchronization Problems
A common problem is that one earbud plays and the other is silent, even though both are in the ears, or the phone sees them as two different devices. TWS-To eliminate this, you need to perform a complete reset).
Place both earbuds in a case. Press and hold the touch zones on both earbuds simultaneously for 10-15 seconds (while they are in the case or immediately after extraction, depending on the model). The indicators should flash red several times. This means that the headphones' memory is cleared and they are ready to re-mating with each other.
⚠️ Warning: After reset, you need to re-remove the device from the Bluetooth list on the phone and conduct the pairing procedure from scratch.
If the problem persists, check the charging contacts in the case. Dirt or oxidation can cause one of the headphones to fail to charge or turn on, even though the indicator on the case is on.
What if the reset didn't help?
Specificity of connecting different models Xiaomi and Redmi
Different product lines have their own characteristics, such as Mi True Wireless Earphones 2, which supports fast pairing through a pop-up window, but requires a Mi Account for full functionality, while budget Redmi AirDots rely solely on standard Bluetooth protocols.
Active noise-canceling models like the Mi Air 2 Pro can behave strangely in mono mode. Noise-making microphones may not activate unless the second earpiece is removed. This is normal behavior, laid down by the manufacturer to prevent acoustic feedback.
- 🎧 Redmi Buds 3/4: Supports the Xiaomi Earbuds application for management configurement in mono mode.
- 🎧 Mi AirDots S: Requires accurate pin-code hits when reset (often 0000 or 1234).
- 🎧 Xiaomi Buds 3T: Have an improved switching algorithm, but are sensitive to the Android version.
Owners of older models, such as the first AirDots, may need a longer sensor retention to enter pairing mode.Always check the official documentation for your specific device revision.
