This is an invisible bluetooth headset connected to your ear drum inside your ear.
It was used by secret agents in the past but seems like this thecnology is outdated to FBI or CIA so they decided to start selling it , probably to get money for more crazy gadgets they make in Area 51 ........
This little peace of equipment could be verry usefull if it wasent so dangerously unstably designed .. oh well i guess we will have to wait for few year until the secret service decided to relise the ubdated version.
