I received the following e-mail in April 2003:
My name is Lincoln, and living in Santiago, Chile, in South America. Yes, the
company of the Chief Headphones is C. F. Cannon of Springwater, New York
City. This company, after the merger with the Chester Brandes Company (about
1940's) they made the headbands cheaper with simple metal bands, no cloth
padding. The earcaps were made of plastic with the multiple small listening
holes instead of the one central hole. The magnets were also changed from
the flat curved shape to a tubular curved shape. Saving money I guess.
The Brandes headphones have been developed over a period of twelve years.
They were originally designed by Reginald Fessenden, one of the world's
greatest radio experts. I attach some information about Chester Brrandes
Company (the original company).

Lincoln also included an excerpt from a 1922 book that details
this type of headphone. I've converted it to HTML, which you
