They help improve productivity and safety on the job site by eliminating the mistakes that come from missed or misunderstood communication. Listen-through technology lets the user toggle the right amount of outside sound for a boost of awareness and safety. Teamwork improves as users stay in touch across the work zone and easily coordinate complex tasks with better focus and concentration. It helps users train in the moment, instruct for precision and correct mistakes instantly while the work continues.
