With an integrated microphone and speaker, both voice transmission and receiving are activated in ear. A low profile in ear microphone speaker provides clear communication in high noise operations. An in-ear bone conduction speaker-microphone conducts sound to the inner ear through the bone of the skull. External sounds are not inhibited, as the ear cavity is unobstructed. The in-ear speaker-microphone may be worn independently with hearing protection. Allows the user to employ hearing protection on a need basis. Maintain radio communications at all times.
