The POCO X7 does not support Bluetooth audio sharing.
Bluetooth audio sharing on a smartphone refers to a feature that allows the device to stream audio simultaneously to multiple Bluetooth audio devices, such as headphones, earbuds, or speakers. This feature is particularly useful for those who want to share audio, like music, or a video, with another person without needing to pass the headphones or use a splitter.
Bluetooth audio sharing works best with Bluetooth 5.0 and later versions, which offer better data transfer rates and the ability to support multiple connections simultaneously.
