Abstract
An earpiece includes an open tip in the shape of a dome, with apertures in the dome and a protrusion at the top of the dome for displacing ear wax, wherein the dome merges with the protrusion along a continuous curve. The dome is supported from a central body by non-linear ribs that normally have high compliance but exhibit low compliance at a limit of extension or compression. The tip can include more than one dome on the central body. If there is more than one dome, the apertures in the domes are not aligned with each other.
