EDESON RADIO 1500
This is an interesting thinly veiled infringement on the Edison
name. Still it has a cute radio icon and 3000 ohms for the pair,
rare set, circa 1924.
Notes:
The Dictograph R-1, R-3, and Aristocrat look like more modern
headphones but the magazine ads show they were made in the
1923-1925 era and they have very good tone and sensitivity for
crystal radio use.
Durophone and Dymac were fairly cheap consumer grade headphones.
The Elwood and Everett headphones were good quality made sets.
The Eisemann headphones weresolid and well built, hard to find.
The Eosh and Edeson sets pictured above must be rare as I have
never seen another pair of either than these ones.
