What is the difference between Bluetooth 5.0 and Bluetooth 5.2 headsets?

Bluetooth 5.2 offers an upgraded version of the original Attribute Protocol (ATT) compared to 5.0, called Enhanced Attribute Protocol (EATT), which is more efficient and secure than ATT. And Bluetooth 5.2 offers Synchronized Channel (ISOC)-a brand new feature that supports both connection-oriented and connectionless communication. With these advancements and efficiency gains, Bluetooth 5.2 offers faster pairing capabilities and longer battery life.
