Why Xiaomi Headphones Don’t Connect to Your Phone – and How to Fix It

Xiaomi’s wireless headphones are among the most popular gadgets, thanks to a combination of price, sound quality and battery life. However, even with devices such as the Redmi AirDots 3 Pro, Xiaomi Buds 4 or Haylou GT7, users face synchronization problems, most often due to firmware failures, conflicts with other Bluetooth devices or banal errors on the first connection.

In this article, we will discuss all the ways to connect Xiaomi headphones to Android and iOS smartphones, including forced resetting and solving typical errors like “device not found” or “cannot connect.” Particular attention will be paid to models with dual mode support (simultaneous connection to two devices) and headphones with ANC (active noise cancellation), where the pairing process may differ.

If your headphones have been connected before, but suddenly ceased to be determined by the phone, the first thing to check is not activated mode "Invisible" in the Bluetooth settings - this feature is in the firmware MIUI 14+ and often turned on accidentally.

Preparing for connection: what to do before synchronization

Before you start pairing, make sure your phone and headphones are ready to connect.

• 📱 Update the firmware of the smartphone: on Android, check the relevance of the version in Settings → The phone. → System Update. For iPhone, go to Settings → Mainstream → Update of the PO.
• 🔋 Charging headphones: battery level should be at least 30%. If the indicator on the case flashes red, connect it to charging for 10-15 minutes.
• 🎧 Resetting previous connections: if the headphones were already paired with another device, they need to "forget" in the Bluetooth settings of that gadget.
• 📲 Remove old profiles: In the Bluetooth phone menu, find a list of paired devices and remove your Xiaomi headphones from there (if there are any).

For models with support for Xiaomi HyperSync (for example, Buds 4 Pro), you will additionally need to install the branded Xiaomi Earbuds application from Google Play or the App Store. It is necessary not only for audio tuning, but also for the correct operation of the automatic switching function between devices.
