The Xiaomi Redmi Buds 5 are not designed to be connected directly to an LG TV. These headphones use Bluetooth 5.3 technology, which is primarily intended for mobile devices such as smartphones and tablets. Connection to a TV would require specific compatibility with the TV's Bluetooth technology, which is not mentioned in the product specifications.

If your LG TV supports Bluetooth connection, you could still try to connect a headset, but it is not guaranteed to work properly. In general, to connect wireless headsets to a TV, it is often necessary to use a specific Bluetooth adapter.
