CavCom's Talk Through Your Ears technology combines hearing protection with an in-ear microphone and speakers to allow seamless voice communication in high noise environments while wearing protective equipment. It protects hearing at up to NRR 32, uses volume-limited speakers to deliver clear radio audio to both ears, and has an earpiece microphone that transmits voice from inside the ear canal for clear speech in loud noise or when wearing a respirator. Custom fit or universal earpieces are available to suit specific needs and work with any two-way radio.
