The CM-i5 is the latest addition to the company's radically new and patented line of in-ear headsets. The CM-i5 includes a slimmer, lighter noise-cancelling condenser microphone designed for clarity and all-day wearing comfort. The new headset is among the world's only modular in-ear headsets offering a revolutionary combination of in-ear performance, lightweight comfort and earphone modularity. The robust feature set makes the headset ideal for broadcast teams from directors to camera operators who rely vitally on the ability to hear clearly-and react quickly in order to capture live action shots. Headset Satisfaction from Sports to SpaceThe one-of-a kind design of our patented headsets brilliantly captures what traditional headsets have been lacking. For anyone who must work in loud environments or have health concerns about sharing headsets or bulky headsets that weigh too much, this solution will give them relief from all these problems. The headset's low profile binaural earphone feature is a simple yet inventive method to block out noise and boost audio clarity-solving many age-old dilemmas experienced by headset wearers.
