Wireless headphones have become an integral part of everyday life, especially for owners of Xiaomi Redmi smartphones. However, even with modern technologies, users often face problems: headphones do not connect, sound is interrupted or quality leaves much to be desired. This article will help you understand all the nuances of setting up Bluetooth headphones on Redmi devices – from basic pairing to advanced features like codecs and multipoint.

We will consider not only the standard connection procedure, but also little-known chips. MIUI, So, for example, how to turn on low latency for games, or why the Redmi Note 12 might not see AirDots after the upgrade, and if you're faced with a situation where one earbud stopped working, you can find a solution here.

Important: instructions are relevant to all modern Redmi models (from Redmi 9 to Redmi Note 13 Pro)+) and most wireless headphones – both original Xiaomi (AirDots, Buds, FlipBuds), and third-party (Sony) WH-1000XM5, JBL Live Pro+ We will pay special attention to the problems specific to firmware. MIUI.

1. Connection Preparation: What to Check Before Connection

Before you start setting up, make sure your headphones and smartphone are ready to go, and connection problems often arise from trivial omissions:

After successful connection, the list will be connected. On some Redmi models (for example, Redmi Note 11 Pro) next to the headphones will display a battery icon – this means that the smartphone supports the display of the charge level of the accessory.

If the headphones don’t appear on the list, try:

• 🔄 Reboot the Bluetooth module of the smartphone: turn off / turn on Flight Mode or restart the phone.
• 📱 Update Bluetooth service via Google Play (Bluetooth app) MIDI Services).

LDAC — Maximum quality for Sony WH-1000XM4/XM5, but can cause stuttering at a weak signal. LC3 — new standard for Bluetooth 5.2+ (Supported by Redmi Note 12 Pro+ newer).

Critical information: On Redmi with Snapdragon processor 7xx/8xx (Like Redmi. K50) codec LDAC It may not work smoothly due to problems with Qualcomm drivers, in which case select aptX Adaptive or AAC.

To reduce the latency of sound (relevant for games and videos):

1. Turn on the game mode in the headphone settings (if any).
