INVISIO X50 Wireless In-Ear Headset with Bone Conduction and Active Hearing Protection for Tactical Communications

The INVISIO X50 is the in-ear headset designed for special forces operators who need to resolve the central contradiction of modern tactical headsets: the hearing protection that blocks gunfire impulses also blocks direct verbal communication with adjacent teammates and environmental alert sounds — breaking branches, threatening voices, approaching vehicles — that are the most critical information source in CQB operations.

The X50 resolves this through an integrated bone conduction system in the in-ear plugs: two piezoelectric transducers capture skull vibrations generated by nearby voices and transmit them directly to the cochlea, while the headset's directional ambient microphone amplifies low-intensity external sounds (<75 dB SPL) in real time — allowing the operator to hear whispers at 5 meters while their ears are fully sealed against 170 dB gunfire impulses.

NFMI (Near Field Magnetic Induction) connectivity eliminates the audio cable between the headset and the INVISIO controller, operating in the 10 MHz band with up to 30 cm range — sufficient to reach from the ear to the controller on vest or belt — without interference from military radio frequencies. The NFMI link consumes 0.8 mW, extending internal battery life to 36 hours of continuous use, compared to 8-12 hours typical of conventional Bluetooth headsets.
