Bric-a-brac: Ericsson Headphones
|
Ericsson headphones in original box from the
early 1930's. What ugly and uncomfortable things they are.
Made from steel with bakelite ear covers, these sit awfully on the head
and the ear pieces don't appear to be designed for humans.
This type of headphone was typical in the early wireless days, either for crystal sets or (one or two) valve sets without output stages to drive a loudspeaker. I'm not sure what the orange and black design is supposed to represent behind the Ericsson logo, though it's quite nice. These images have been heavily processed and the side picture is probably more representative of the original red colour used. The 4000 ohm resistance was actually 2000 ohm per earpiece as they were wired in series. British Ericsson's |

This is the same company that is today famous for its (Sony/Ericsson) mobile phones. However, during this period, it was only a famous name in Scandinavia. |
