CM-i3 Intercom Headset


Specifications •• Accessories •• Product Reviews

The CM-i3 is the world's first modular intercom headset. This intercom headset has a patent protected slim-line design that allows for three listening modes. Rather than having to remove the entire headset to check environmental sounds or interact with others, simply remove one or both earphones to exit the listening mode or monitor a mix of feed audio and surrounding acoustics. The CM-i3 intercom headset is designed for concert venues, front of house operations, multimedia production and other professional trades relying on convenient two-way communications.
