Abstract: A retaining piece for an earpiece of an in-ear audio output device comprises a retainer portion and a cantilevered portion. The cantilevered portion comprises a coupling edge and a free edge which is substantially opposite the coupling edge. The cantilevered portion is coupled to the retainer portion at the coupling edge and is configured to engage with at least a part of an outer wall of a concha of a user's pinna. The cantilevered portion comprises a convexly curved section between the coupling edge and the free edge. When the cantilevered portion is in an engaged state, the coupling edge is more medial than the free edge.

Abstract: An earpiece includes an electro-acoustic transducer and a housing that supports the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume. The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume and a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. A mesh is disposed along an outlet of the housing and is arranged to inhibit debris from entering the front acoustic volume. A first microphone is supported in the housing. The first microphone includes a microphone port for sensing pressure. A chimney surrounds the microphone port and mechanically couples the first microphone to the mesh.
