Hammerhead Wireless - can the earbuds be used independently (only one)?

I am interested in the razer hammerhead true wireless pro and the true wireless v2 (2021) earbuds. However, I often am in a situation to wear only one earbud and would like to leave the other in the case. Is this possible with these earbuds, or do they have a master/slave configuration that requires always a specific earbud to be used?
