1. An earpiece comprising:
an electro-acoustic transducer;
a housing supporting 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 being arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume and such that a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume;
a mesh disposed along an outlet of the housing and arranged to inhibit debris from entering the first acoustic volume;
a first microphone supported in the housing, the first microphone comprising a first microphone port for sensing pressure; and
a chimney surrounding the first microphone port and mechanically coupling the first microphone to the mesh,
wherein the chimney is secured directly to the mesh via adhesive or heat staking.
