The customized submersible in-ear headset for use both in and out of the water

INVISIO M4s combines the customized and truly personalized in-ear fit and extended comfort with the submersibility of INVISIO M3s. Resulting in a completely sealed microphone and loudspeaker housing allowing for diving down to 20 meters (IP68 compliant).

Noise Elimination System

INVISIO M4s 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.
