Why Xiaomi Airdots headphones work separately: technology and nuances of use

Xiaomi Airdots wireless headphones (and their modifications — Redmi Airdots, Mi True Wireless Earbuds) have become one of the most popular accessories due to the combination of price, quality and convenience. One of the key features that distinguishes them from the competition is the ability to use each headphone separately. But how does it work technically? Why can one headphone play music without a second, while many other models require synchronous pairing?

In this article, we will take a closer look at TrueWireless technology, which is the basis for independent headphones, explain how smartphone connectivity is implemented, and reveal the nuances to consider when using Airdots in solo mode, and learn about possible problems (for example, when one earphone refuses to work separately) and how to solve them.

What is TrueWireless Technology and How Does It Work in Xiaomi Airdots?

The term TrueWireless (or TWS — True Wireless Stereo refers to wireless headphones that do not have a physical connection not only to the sound source (smartphone, tablet), but also to each other. Unlike traditional Bluetooth headphones, where one headphone is a master and the second one is a slave, in which the headphone is a master. TWS-Both systems connect to the device independently.

In the case of Xiaomi Airdots, a hybrid scheme is implemented:

• 🔹 The lead headphone (usually the right one) connects to the smartphone directly via Bluetooth and transmits an audio signal.
• 🔄 The led earphone (left) is synchronized with the lead on a separate channel, but can also work autonomously if the lead is disabled.
• 📶 Both headphones support Bluetooth 5.0 protocol, which provides stable connection at a distance of up to 10 meters (without obstacles).

It is important to understand that independent work is possible thanks to an integrated chip (in different models Airdots use solutions from Qualcomm or Realtek), which controls the synchronization and distribution of sound. For example, Redmi Airdots 3 Pro has a Qualcomm QCC3040 chip that supports advanced AAC and aptX codec, which improves the sound quality even when used separately.

How to connect Xiaomi Airdots separately: step-by-step instructions

You can use Xiaomi Airdots headphones separately in two ways: mono (one earpiece) or stereo (both earphones, but with the ability to disable one).

1. Take both earbuds out of the case, and they automatically turn on and sync.
2. On your smartphone, activate Bluetooth and find the Mi True Wireless device (or similar name for your model).
3. Once you've successfully connected, put one headphone back in your case, and the other one will continue to play the sound in mono mode.
4. To return the stereo mode, just take out the second headphone from the case - it will automatically connect to the first.

If the headphone doesn’t want to work separately, try:

Reset the headphone settings (press the button for 15 seconds)|Remove the device from the list of conjugates in Bluetooth|Reboot your smartphone|Update the headphone firmware (if available)-->

Note that in some models (for example, Redmi Airdots 2) to activate mono mode may require a double touch on the touch panel of the headphone.

💡

If the headphone is quickly discharged in mono mode, check the Bluetooth settings on your smartphone: some devices (especially on Android 12+) optimize power consumption for TWS, which can affect autonomy.

Technical limitations: when separate work is not possible

Despite the stated support for independent operation, in some cases Xiaomi Airdots may refuse to function separately.

Especially often problems arise with the first-generation Redmi Airdots, where the firmware does not always correctly handle the transition to mono mode. In new models (for example, Mi True Wireless Earbuds Basic 2S), this problem is solved by improving the synchronization algorithm.

⚠️ Note: If you use headphones with iOS devices, you may need to manually configure lead/subject roles through special applications (e.g. Bluetooth Auto Connect). TWS-regime.

Advantages and disadvantages of using a single headphone

Using Xiaomi Airdots in mono mode has its pros and cons. Let's take a closer look at them:

• ✅ Battery savings: One earphone discharges more slowly than a pair.
• ✅ Convenience in everyday situations: for example, while talking on the phone or listening to podcasts.
• ✅ Safety: One earphone allows you to hear surrounding sounds (relevant to the street or office).

However, there are also disadvantages:

• ❌ Deterioration of sound quality: in mono mode, the stereo effect is lost, the basses become less pronounced.
• ❌ Mikphone problems: If the lead headphone (with microphone) is turned off, the ability to answer calls may be lost.
• ❌ Unstable connection: Some Airdots models lose touch with a smartphone when using a single headphone at a long distance.

Fun fact: Redmi Airdots 3 Pro has an ENC (Environmental Noise Cancellation) microphone technology that even works in mono mode, making them among the best in the lineup for calls.

Comparison with competitors: how independent work is implemented in other brands

TrueWireless technology is not only used by Xiaomi, but let’s compare how independent headphones are implemented by other manufacturers:

Xiaomi’s main difference from competitors is the flexibility of the setup. For example, in AirPods, mono mode is activated automatically when you remove one earbud from a case, while in Airdots, manual reconnection is sometimes required. On the other hand, Xiaomi offers more customization options (for example, assigning touch actions).

If you’re critical to mono-mode stability, look for models with Qualcomm chips (like Redmi Airdots 3 Pro or Mi True Wireless Earbuds 3) that are better optimized for independent operation.

Frequent errors of users when using mono-mode

Many of the problems with the individual work of Xiaomi Airdots arise from the wrong actions of users.

1. Using a non-original case, cheap ones can charge headphones incorrectly, which leads to synchronization failures.
2. Ignoring firmware updates. Newer versions often fix mono-mode bugs.
3. Connecting to multiple devices at once: Some Airdots models don't support multipoint, which can cause conflict.
4. Incorrectly removing the earphone from the case, a sudden movement can interrupt the synchronization process.

⚠️ Note: If you use Xiaomi Airdots with Windows or macOS devices, the mono mode may not work stable due to the features of the implementation of the Bluetooth stack in these OSes.

Also, remember that mono mode increases the load on one earpiece, which can cause it to overheat with prolonged use. If the earpiece gets hot, let it cool for 10-15 minutes.

💡

For maximum stability of mono mode, use headphones with firmware not lower than version 1.4.0 (checked in the Xiaomi Wear application).

The future of technology: what awaits TrueWireless headphones Xiaomi

Xiaomi is actively developing a lineup TWS-It's a headphone, and newer models are getting more and more perfect mono mode. For example, in Xiaomi Buds 4 Pro (2023) implemented:

• 🎧 Dynamic role distribution: any headphone can become the leading.
• 🔋 Adaptive energy savings: in mono mode, the headphone consumes 20% less charge.
• 🎤 Double microphones in each earphone for better call quality.

Support is expected in future models LE Audio (low-energy audio protocol), which will further improve autonomy in mono mode. AI-synchronization, which will automatically adjust the sound to the acoustics of the room even when using one headphone.

If you are planning to buy new headphones and you are important mono mode, pay attention to models marked "Dual Master" - they are optimized for independent work.
