An earpiece includes an electro-acoustic transducer, a housing that encloses the electro-acoustic transducer, and a nozzle. The nozzle is coupled to the housing and is configured to direct acoustic energy from the transducer toward a user's ear canal when the earpiece is worn. The nozzle defines an inlet opening, an exit opening, and an acoustic pathway extending therebetween. A microphone is disposed within the nozzle and includes a microphone port. A chimney acoustically couples the microphone port to the exit opening and at least partially defines an effective port for the microphone. The inlet opening is closer to the electro-acoustic transducer than the exit opening such that acoustic energy radiated by the electro-acoustic transducer travels from the inlet opening toward the exit opening. The effective port is closer to the exit opening than the microphone port. The effective port is spaced from an exit opening of the nozzle.
