View of the Globe Audi-Aid with the handle pulled down the extended
position as it would be when used. You held the Audi-Aid earphone part flat against
your ear with the cone facing forward.
Because of the diaphragm ear
piece, they offer considerable gain in the high frequencies.

Rear view of the earphone of the Globe Audi-Aid showing the
manufacturer. The raised inscription reads "GLOBE PHONE MFG CO.". This dates this Audi-Aid to 1920 as the company changed their name
from the Globe Ear-Phone Co to the Globe Phone Mfg Co. in January,
1920.
It couldn't have been later, as in 1921 they moved to Reading, MA from
Boston. (See picture below.)
