How to connect both Xiaomi wireless headphones to your phone via Bluetooth: a step-by-step guide

Xiaomi wireless headphones are a popular accessory for music lovers and active smartphone users. However, many people face the problem: after buying or resetting the settings, only one headphone is connected to the phone, and the second one remains silent. This situation is especially annoying when you want to enjoy stereo sound or use the noise reduction function. In this article, we will discuss why this happens and how to properly synchronize both earphones with your phone via Bluetooth.

The problem isn’t always a problem with a device malfunction. Most often, the fault is the wrong connection sequence, outdated headphone firmware or conflict with other Bluetooth devices in the phone’s memory. We’ll look at universal methods for all Xiaomi models, from the budget Redmi AirDots to the flagship Xiaomi FlipBuds Pro. And if the standard methods don’t work, you’ll find alternative solutions here.

Why is there only one Xiaomi headphone?

Before we get to the instructions, it's important to understand the cause of the problem, and here are the most common scenarios.

• 🔋 A discharged battery in one of the headphones – the device may not show signs of life until it is charged.
• 🔄 Reset pair – headphones “forgot” each other after prolonged inactivity or mechanical shutdown.
• 📱 Bluetooth profile conflict in phone – if other headphones or speakers have previously connected, the system can “confuse” them.
• 🔧 Outdated firmware headphones or smartphones – especially relevant for models older than 2021.
• 🎧 Mechanical damage to contacts in the case or the headphones themselves (for example, after a fall).

80 percent of the time, the problem is solved by resetting your headphones and re-syncing, but if you've tried this before, read on, we'll look at some advanced methods.

⚠️ Note: If Xiaomi headphones never connected at the same time (even after you bought them), check them on another phone.

Preparation of headphones for connection: checking and charging

Before setting up, make sure both headphones are ready to work:

1. Charge. Place the headphones in the case and plug it into the power source for 10-15 minutes. The headphones should flash red (charging) or burn green (full charge).
2. Remove both headphones from the case, they must automatically turn on (white/blue LED flashes).
3. Synchronization check. If the headphones are synchronized, you'll hear a beep (usually a short double beep) if there's no beep, you need to reset.

For touch-controlled models (such as the Xiaomi Buds 3 Pro), check that the headphones do not lock touches. Sometimes, accidentally pressing during extraction from the case turns off one of the headphones.

Reset Xiaomi headphones to factory settings

If the headphones are not synchronized with each other, the first thing to do is to perform a hard reset.

For Redmi AirDots and Mi True Wireless:

1. Place both headphones in the case and close the lid.
2. Open the lid and hold the button on the case for 15-20 seconds until the indicator starts flashing red and white alternately.
3. Get the headphones out – they should automatically synchronize (double signal will sound).

For Xiaomi Buds 3/4 Pro and FlipBuds Pro (touch models):

1. Put the headphones in the case.
2. Press and hold the touchpads on both headphones simultaneously for 10 seconds until the indicators flash red.
3. Get the headphones out - they will reboot and sync.

• 📱 On iOS, automatic switching between devices may not work (for example, from phone to laptop).

How do I check that both earphones are working?

Once connected, make sure the sound is going to both earphones. Here are some simple tests:

• 🎵 Play music. Play any song and check the balance. If you hear only the left or right channel, go back to the Bluetooth settings.
• 📞 Call another phone and ask the person to tell you if they can hear you on both earbuds (relevant for models with microphones in each earbud).
• 🔊 Transparency mode. Activate it (if you have one) - you should hear the surrounding sounds equally clearly in both headphones.

For accurate diagnosis, use applications like SoundCheck (Android) or Decibel X (iOS), which show the sound level in each channel separately.

💡

If after all the manipulations, one earphone still does not work, check it on another device. If the problem persists, it is a hardware malfunction (for example, a damaged speaker or Bluetooth module).
