INVISIO® M3h 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 extreme situations with no interference commonly
found when communicating in these environments.
INVISIO® M3h offers unsurpassed performance, comfort and fit for professional users. Utilizing a form factor
that has been researched and designed over the last decade, the patented Soft Spring™ adapts perfectly to the
contours of the ear offering maximum comfort as well as a secure fit. The Soft Spring™ can be easily adjusted
in length to perfectly fit the contours of any ear. This allows compatibility with helmets, eyewear, gas masks or
circumaural headsets. INVISIO® M3h is the ultimate tactical headset.
