Connecting wireless headphones to Xiaomi TV via Bluetooth: full instruction

Wireless headphones have become an integral part of the modern home theater, but their connection to Xiaomi TVs often raises questions among users. Unlike smartphones, where Bluetooth connectivity is set up in a few seconds, TVs require a more careful approach – especially when it comes to models with a high-speed connection. MIUI TV Google TV Problems can occur with both finding the device and with synchronization of sound, delays or sudden communication interruptions.

In this article, we’ll look at all the ways you can connect, from standard pairing through the settings menu to alternative methods for older models without built-in Bluetooth. You’ll learn how to check the compatibility of your headphones with your TV, which codecs provide the best sound quality, and what to do if the TV “can’t see” the device. And for those who are faced with a latency of more than 200 ms (a critical threshold for watching movies), we’ve prepared a separate section with solutions.

Method 1: Bluetooth transmitter for TV

Devices like this. 1Mii B06 Pro or Avantek APT-X They connect to an optical output or 3.5 mm audio jack of a TV and relay the sound over Bluetooth:

• 🎛️ Support for aptX Low Latency (latency) <40 miss).
• 🔋 It works from USB-TV port (does not require a socket).
• 🔄 Possibility to connect up to 2 pairs of headphones at the same time.

Instructions for setting:

1. Connect the transmitter to the optical output of the TV (port) S/PDIF).
