Delivering value, comfort, and sound quality, our E6 Omnidirectional Earset Microphone provides the same impressive performance as our E6i Omnidirectional Earset with a more rigid boom and smaller silicone pad. Practically invisible to live or broadcast audiences, the E6 is incredibly comfortable for the wearer. It captures the closest source clearly with excellent rejection of wind, ambient noise, and feedback. And its industry-unique snap-on cable extends the equipment life many times over. In addition, the snap-on cable makes your E6 compatible with virtually any wireless mic system - just buy a new cable instead of a new mic! We've mounted our tiniest mic capsule on an even tinier boom that is rugged and incredibly lightweight. A thin silicon pad at the earpiece helps keep the boom comfortably in place, even with glasses or other head-worn accessories. We offer the widest range of boom colors to match virtually any skin tone, and each mic can easily be custom-fitted to any wearer. Once adjusted to fit your head, the tough springy boom keeps its shape when stored. It's no surprise that Countryman's E6 Omni Earset a top choice for presenters, educators, worship leaders and pastors, broadcasters, and many, many more! The E6 Omni microphone is supplied with a snap-on cable with specified connector, windscreen, set of three protective caps, set of two collar clips (black and white), and carrying case.
