OS excllent find! and can we get what year they were round? ie the late 1920?
And i a assuming they would have cost a bit .
The next batch had more luck and by 1899 an electrically powered hearing aid could be purchased for around $400. This table sitting design with a microphone made of carbon, battery box and earpiece was far beyond the means of most, who worked for only a few dollars wage a week.
The twenties and thirties would see improvements with vacuum tubes being used as a better delivery tool for the gathered sound in a hearing aid, and also the invention of the Bone Conductor in 1933. This might sound like the name of a cartoon character that leads an orchestra made up of skeletal musicians, but was actually a very effective way of helping people to hear by sending sound through the bone at the side of the skull behind the ear, and bypassing the poorly performing ear. If you could put up with the headaches.
Increased portability was now the name of the game for electric hearing aids, and the thirties and forties saw many designs from competing manufacturers. Yet, whilst this may have been a noble goal, the physical results were large, cumbersome and expensive.

Maybe it's a get smart shoe phone.
She's holding something. But maybe she's just a little crazy and speaking into a shoe.

Wouldn't a time traveler be able to spring for a bluetooth?
By the way, who could she be talking to, there were no cell towers in that day and age. No way for the signal to be picked up and delivered to another device.
