Xiaomi’s headphone doesn’t play: why it happens and how to fix it

You took Xiaomi's favorite wireless headphones out of your case, turned on the music, but it only came from one device? This problem is familiar to many owners of Redmi AirDots, Mi True Wireless and other models of the brand. The reasons can vary from a trivial connection failure to hardware malfunctions. In this article, we will analyze all possible scenarios why one Xiaomi earphone does not play, and give clear instructions for troubleshooting.

It's important to understand that if the headphone is completely dead (it doesn't blink, it doesn't respond to charging), it's hardware damage -- it's only the service center that will help. But 80 percent of the time, it's software-based, like resetting, updating the firmware, or cleaning the contacts. We've put together proven methods that work for most Xiaomi models, including AirDots 2/3, Mi Earbuds Basic, and Buddy.

So don't rush to throw out your headphones or carry them for repair, check our recommendations first, and many users have returned the devices to work just by following basic diagnostic steps, and let's start with the simplest and gradually move on to more complex solutions.

1. Checking basic settings: why the headphone can "silence"

Before disassembling the headphones or resetting them to factory settings, make sure the problem isn't with your smartphone or device settings. Often the sound is lost due to randomly activated functions or Bluetooth failures.

The first thing you need to do is to reboot your smartphone and your headphones.

• 📱 Turn off Bluetooth on your phone, wait 10 seconds and turn it on again.
• 🎧 Take both headphones out of the case, put them back for 15 seconds, then remove them.
• 🔄 Reboot your smartphone (especially relevant for the Xiaomi/Redmi/Poco shelled MIUI).

If the sound does not appear after the reboot, check:

• 🔊 Volume balance in sound settings (sometimes one channel accidentally dimmed to 0%).
• 🎵 Mono/stereo mode – some apps (e.g. YouTube Music) may force monosound.
• 📱 Connect to another device – it may be that the headphone automatically connected to a laptop or tablet.

If the basic manipulations did not help, move on to the next step - reset the headphone settings.

2.Reset Xiaomi headphones to factory settings

Reset is a universal method that solves most software failures. The process may differ from Xiaomi to model, but the general logic is the same: you need to force the headphone settings to reset so that they “forget” all previous connections and errors.

Instructions for most models (Redmi AirDots 2/3, Mi Earbuds Basic):

1. Put both headphones in the case and close the lid.
2. Pull them out and hold the touchpads on both headphones simultaneously for 15 to 20 seconds until the lights start flashing red and white.
3. Once reset, the headphones will automatically turn off. Turn them on again and connect them to the phone as a new device.

For models with buttons (e.g. Mi True Wireless Earbuds Basic):

• 🔘 Press and hold the button on the case (if any) for 10 seconds.
• 🎧 Or press the button on the earphone itself (if physical) for 10-15 seconds.

Make sure your headphones are charged at least 30 times%|

After reset, the headphones may require a firmware update, which is discussed in the next section.

3. Firmware Update: Why It Matters

Outdated firmware is one of the main reasons why one Xiaomi earphone doesn't play or shut down.The manufacturer regularly releases updates to fix bugs with sound, connectivity and synchronization.

Refreshment methods:

• 📱 Through the Mi Home app (for models with support): Open Mi Home → Find your headphones in the list of devices. Go to Settings → Update firmware. If a new version is available, click Update and wait until it's finished (don't turn off the headphones!).

Through the PC.

1. Download the official firmware from Xiaomi’s website (for example, for AirDots – here).
2. Connect your headphones to your PC via Bluetooth and use the Mi Flash Tool utility.

⚠️ Warning: Don't interrupt the upgrade process! If the headphones go off during firmware, they can turn into a brick. Charge them to 100% before starting.

If the problem remains after the update, check the physical condition of the headphones - perhaps the contacts or battery are to blame.

4.Bleaking contacts and checking charging

Over time, the charger contacts of the headphones and the case accumulate dust, oxides or fat, which leads to poor contact. If one earphone does not charge, it may automatically turn off or not play sound.

You'll need:

• 🧻 Cotton swab (dry or soaked in alcohol).
• 🔦 Contact light.
• 🧲 Soft brush (for example, for drawing).
• 🎛️ Forced synchronization: Take both earbuds out of the case. Touch the touchpad on the right earbud 3 times in a row. Wait 10 seconds.
