Anker liberty neo single & dual use question

everytime i use one earphone on its own i cant seem to get then working togther again so i have to reset both of them -is there any way i can use one earphone while still allowing it to work with the other earphone - or must I reset it every time I use a single earphone when I want to use both together?

Unless your phone supports dual bluetooth audio, you will have to reset them to use together…although you can always use just the right without having to reset them

So I only have to reset them if I use the left earphone on it’s own am I right?

Bluetooth 5 required, so I understand.
