A communication device and overmold (100) adapted to minimize the feedback, acoustic coupling, and seismic vibration between a speaker (207) and microphone (202) in close proximity, as is typically found in hands-free headsets, is provided. This invention, through the use of specific structure s absorbs unwanted noise and sound waves thereby improving the performance of the communication system as a whole. The complete system of this invention i s provided in several embodiments, including an embodiment where the microphon e is inserted within the overmold structure, an embodiment where the microphon e is a boom microphone and an embodiment where the microphone is somewhat remo te (a few inches) down from a miniaturized overmold and is provided with an ON/OFF switch.
