Kawamura Ganjavian’s “Earshell”:
We use earrings as symbols of distinction since time immemorial, however they are not particularly useful items. The EARSHELL is a simple, efficient and elegant sound enhancing device. It can be used to improve our listening of music or opera. Its refined and sleek profile gives it a jewellery feel.
Not quite these, but interesting to see the idea proposed as jewelry. Of course, the inclusion of “opera” specifically is an appeal to high taste. I think the picture is probably cropped like that on purpose, to hide the fact that you’d most likely end up looking like this if you wore them.
