Ear Trumpets (Ear Horns)

Kirchner & Wilhelm Two-section German Metal Ear Trumpet (Ear Horn)

This two-section collapsible metal German ear trumpet was manufactured by Kirchner & Wilhelm of Stuttgart, Germany. It likely dates to somewhere between 1910 and 1930 or so. It is made of a non-magnetic metal, probably brass.

In its fully extended position, this ear trumpet is 14" long. It is quite heavy for an ear trumpet, weighing in at 6.8 oz.

The bell section is made of a much thicker metal than the ear-tip section.

Rather than bending the bell to face forward, the mouth of the bell is somewhat scooped (slanted) so the sound can enter more directly.

This ear trumpet has good amplification.

Close-up of the "break" ring. The tapered tube fits snuggly against the bottom section. To collapse it just push the two sections together until they "let go". This makes it easy to twist the ear tip section to fit the left or right ear.
