Invisio Headset, M4h


The customised in-ear tactical headset providing certified hearing protection

INVISIO M4 is the ultimate headset for fit, comfort and ease of use. Made to fit the ear of the individual user and manufactured from an actual impression of the user’s ear. The customized ergonomic design increases comfort and the duration of time the headset can be used for.

Noise Elimination System

INVISIO M4h utilizes the patented Bone Conduction Microphone. It has no external microphone and captures vibrations in the user’s jawbone converting them to crisp and clear sound. No external ambient noise around the user is picked up. As a result, the headset can be used in any combat situation with no interference commonly found when communicating in these environments.
