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.
