You will still get the advantage of energy-efficiency on the earbuds because they are using the 5.2 radios giving better battery life. Also, you will still have the enhanced security of the 5.2 as it is again a feature of the radios in the earbuds. It is harder for someone to hijack the signal from these than if they only had 5.0 radios. It is still using Bluetooth 5 just with newer more energy-efficient and secure.
