Abstract: An in-ear headphone that includes a device housing that defines an interior cavity; a primary acoustic port formed through the device housing; an acoustic driver disposed within the device housing and aligned to emit sound through the primary acoustic port; a deformable ear tip having a sound channel formed through its length and coupled to the device housing such that the sound channel is aligned with the primary acoustic port; and a magnetic alignment system comprising a first set of magnets coupled to the device housing and a second set of magnets coupled to the deformable ear tip, the magnetic alignment system configured to removably couple the deformable ear tip to the device housing and align the ear tip so that it can only be coupled to the device housing in a single orientation.

Abstract: An in-ear headphone that includes: a device housing that defines an interior cavity; a primary acoustic port formed through the device housing; an acoustic driver disposed within the device housing and aligned to emit sound through the primary acoustic port; and a deformable ear tip having a sound channel formed through its length and coupled to the device housing such that the sound channel is aligned with the primary acoustic port, wherein an angle of the ear tip with respect to the primary acoustic port can changed around an indefinite number of axes to change a position and angle of the ear tip relative to the device housing.

Abstract: An earbud comprising: a device housing that defines an interior cavity; a primary acoustic port formed through the device housing; an acoustic driver disposed within the device housing and aligned to emit sound through the primary acoustic port; and a stability anchor protruding away from the device housing at a location adjacent to the primary acoustic port.
