Ear Bone Microphone

The Ear-Bone Microphone combines a bone conduction microphone and in-ear speaker into a single earpiece that fits comfortably in your ear.  The bone conduction microphone converts sound waves into audible transmissions and does not interfere with your gas mask, shroud or helmet.  The earpiece delivers your radio’s speaker output into your ear for clear and private radio reception.  EarHugger’s patented design features an elliptical earpiece with a soft cushion that rotates to make optimal contact in any size ear. The Ear-Bone Mic is ideal for surveillance, SWAT, military and tactical use.
