Abstract
Various implementations include in-ear wearable audio devices. In certain implementations, the in-ear audio devices include an eartip with a body having first and second ends, an inner wall extending between the first and second ends defining a hollow passage to conduct acoustic energy, and a deformable outer wall connected to the inner wall of the body at the first end and tapering away from the inner wall toward the second end, where the deformable outer wall is functionally graded from the first end to the second end to comply with an entrance of an ear canal of a user. In additional implementations, the eartip includes a retaining structure, and at least one of the inner wall or the outer wall of the body, or the retaining structure, has an integral electronic component and/or an electronic component signal trace.
