These quack ear trumpets were made with magnetized metal in original box and seldom found original directions on use. Each side was hand painted for buyer’s skin color. They were advertised “Improved hearing is attributed to magnetism from each ear piece….”. Instruments were also advertised to be invisible as they were inserted inside the ear. The compass was included in case to show the magnetism enhanced sound and could be seen via the compass. We have tested this with seldom found original compass and the ear pieces do move the compass needle. Each ear trumpet plate is marked "Audiphone, Bernard Cie, 7 Rue De Londres Paris". Box is rough, but has preserved instruments in good condition. The velvet lined box is also engraved as Audiphone Invisible Ear Trumpets by Bernard Paris. These date to 1875 to early 1900s. The box measures 4.75 inches and each ear trumpet measures 3” in length.
