Wireless headphones have become an integral part of everyday life, but many Xiaomi users are faced with the problem of how to listen to traditional headphones. FM-radio via Bluetooth headphones, if the smartphone does not support live streaming without wire? In this article, we will discuss all working methods - from built-in functions MIUI to bypass solutions using third-party applications.

It is important to understand that technology FM-Radio in smartphones is originally designed to work with wired headphones (they act as an antenna). However, with the help of software tricks and additional accessories, you can adapt this functionality to the same level. TWS-We tested all the methods on current Xiaomi models. 13/14 series, Redmi Note 12 and POCO X5, to provide proven solutions.

Why? FM-Radio does not work directly with wireless headphones

The main problem lies in the hardware limitations: the chip FM-receiver in Xiaomi smartphones (for example, Qualcomm) WCN3660 or Broadcom BCM4356) It requires a physical antenna, which is a wire from the headphones. The wireless models don't have this component, so the standard app is a physical antenna. FM Radio in MIUI They just don’t see them as compatible devices.

In addition, manufacturers often block this feature at the software level because of:

• 📡 Legal restrictions in some countries (e.g. radio frequency certification requirements)
• 🔋 Savings in battery charge — FM-The chip consumes energy even in the background
• 🎧 Marketing strategy – promotion of streaming services (Mi Music, Spotify)

Algorithm of action:

1. Connect wired headphones to the smartphone (they will act as an antenna).
2. Activate. FM Radio in MIUI (Settings → Additionally. → FM-radio).
3. Connect Bluetooth headphones to the adapter, and the adapter to the audio output of the smartphone.
4. Configure the adapter to transmit audio over Bluetooth (instructions depend on the model).
