Previous articleLost one headphone Xiaomi: 7 ways to return stereo

Losing one headphone from a Xiaomi wireless headset is a bad situation, but it's not a bad one. Unlike wired ones, where a lost module means buying a new pair, wireless devices are not a bad thing. TWS-Headphones often allow you to restore work with even one working device, but the algorithm of actions depends on the model, the version of the firmware and even the circumstances of the loss: fell out on the street, remained in the bag or was stolen.

In this article, we will look at all possible scenarios, from finding a lost earbud through an app to buying an original replacement or flashing the remaining one. We will focus on Xiaomi AirDots, Redmi Buds and Xiaomi Buds models, because their synchronization protocols differ. If you have already tried standard methods (recharging a case, resetting), below you will find expert solutions that are not written in the official instructions.

If the headphone was physically damaged (crushed, flooded with water) or lost more than a month ago, the chances of a pair recovering are minimal, in which case it is more rational to consider buying a new module - this is detailed in the section on replacement.

Now, in order. Let's start with the simplest one: how to find an earpiece if it's just falling under the couch or staying in the jacket.

1.Look for lost earphone through Mi Home app

If your model supports Find Device (available for most Xiaomi headphones after 2020), the chances of finding the gadget are high.The algorithm works via Bluetooth Low Energy (BLE) and shows the last known location, and also allows you to play the audio signal on the lost earphone.

How to check the support function:

• 📱 Open the Mi Home app (or Xiaomi Wear for new models).
• 🔍 Find your headset on the list of devices. 📍 — search function.
• 🔊 Click Find Device → Play Sound: The earpiece will make a loud squeak (even if it's off but charged).

⚠️ Warning: The function only works if the headphone is not completely discharged and is within range of Bluetooth (up to 10 meters indoors.

For Xiaomi AirDots Pro 2, Redmi Buds 3 Pro and later, advanced search with map display is available (requires GPS on your smartphone). If the headphone was lost on the street, check the history of movements in Mi Home → Device → Location History.

2. Alternative search methods: from an audible signal to a metal detector

If the Mi Home app doesn't work, try manual search methods. They're relevant if the headphone is lost at home, in the car or in the office.

Ways to find a headphone without the application:

• 🔦 Lantern + Xiaomi wireless headphones have a glossy surface, they reflect light. Light up the sofas, carpets, gaps between furniture.
• 🎵 Playing audio over Bluetooth, plugging the remaining earbud into your phone, playing music at maximum volume, and if the lost module is nearby, it can automatically connect and make sound.
• 🧲 Metal detector or magnet. Inside the headphones are small metal elements (speaker, battery) and swipe the magnet to the likely places of loss, the earphone may stick».
• 🐕 Pet assistance: Cats and dogs often respond to high-frequency sounds, turn on the phone ultrasound generator (such as the Dog Whistle app) and monitor the pet's reaction.

A critical nuance: if the earphone was in the case when it was lost, its battery will run out much more slowly (on standby power consumption is minimal), so check the case first - it may have rolled under the cabinet.

If the search is unsuccessful, move on to the next step – try to restore the remaining headphone.

3. How to get one earphone to work: reset and reconnect

Many Xiaomi models (such as the AirDots Youth Edition or Redmi Buds 2) can work in mono mode if you reset the settings correctly. This will not return stereo sound, but will allow you to use the remaining headphone for calls or podcasts.

Resetting instructions (universal method):

1. Put the earpiece in the case and close the lid. Wait 10 seconds.
2. Open the case and hold the button on the back (or touch zone on the headphone) for 15-20 seconds until the indicator flashes red and white.
3. Close the case, wait 30 seconds, then open again. The earpiece should go into pairing mode (blinking white light).
4. Connect it to your phone via Bluetooth. If it requests a password, type 0000.

⚠️ Note: After resetting, the headphone can be determined as «LE_Audio» Or "Mi True Wireless" is OK. If the sound is interrupted, try turning off Bluetooth Absolute Volume in the Android developer settings.

For models with firmware 2023+ (for example, Xiaomi Buds 4) may need to update via Mi Home:

1. Connect the earphone to the app.
2. Go to the device settings → Update the firmware.
3. If a new version is available, install it (don’t turn off Bluetooth during the process!).

💡

If the earphone is plugged in, but the sound is only in one channel, check the audio balance in the phone settings: Settings → Sound → Stereo Balance. Sometimes it gets lost after reset.

4.Substitute purchase: Original headphone vs. universal module

⚠️ Note: When buying on AliExpress, check with the seller the version of the headphone firmware. For example, Redmi AirDots 2 came with two types of chips — JL and BES. If the versions don’t match, the headphones don’t sync.

6.What to do if the headphone is stolen: blocking and data protection

If you suspect that the headphone has been stolen, security is a concern, and while Xiaomi’s headphones don’t have any personal data (unlike smartphones), some models retain a history of Bluetooth connections.

How to defend yourself:
