The ultimate intrinsically safe headset for high noise and explosive environments FEATURES ●ATEX and IECEx certified for use in explosive environments Intrinsically safe headset for use in explosive environments ●Vibration sensing Bone Conduc tion Microphone for clear speech and total elimination of ambient noise Total noise elimination system for crystal clear communication ●High performance balanced armature loudspeaker with low distortion Discrete design with superior comfort and secure fit ●Soft Spring™ allows in-ear wearing style for discreet and secure fit Compatible with helmets, gas masks or circumaural headsets ●Ultra light and small, weighing less than 5 grams and measur ing only 1.3 x 2.4 cm ● Kevlar® reinforced silver plated alloy cable with Teflon® insula tion and a pull strength of over 20kg ● Ergonomic Cable Retainer securing cable behind the ear ●Precision made ABS polymer sealed housing for use in extreme environments ●Available in left or right versions INVISIO® M3 Ex 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® M3 Ex 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® M3 Ex is the ultimate intrinsically safe headset.
