In early Covid days, I made hundreds of masks. The most requested were those that had elastic that went around the head because they didn't pull hearing aids out.
My husband wears N95 medical masks with his aids. Back in December he had a real scare - pulled off an earloop mask & lost the device in his one ear in a hospital parking ramp - the very day he got his new aids, and before his insurance was even in effect! Later that evening, when he went to put the other aid in the case, the lost one was there - turns out it was his Bluetooth earbud that got lost, he had switched it out so he could take calls while waiting for our daughter to be discharged.
Trust me, he has told this story to all our friends, and always double checks his aids when he puts the mask on or off.
