I feel like audio designers were not prepared for how many people prefer a one ear device. Despite how common it was to see someone with a single headphone dangling awkwardly.

It is perfect for Pod casts, Audio Books, Phone calls and about 90% of my normal Air Pod use.

Many headsets made for phone communication are mono. Perfect for switch-board usage from the old times. One ear for the phone, the other for talking to colleagues.
