Invisio G5 World’s Smallest Bluetooth Headset

Must me my day for reporting on Bluetooth devices, or maybe I just like reporting on the "World's Smallest" of whatever. So, let's get this out of the way: The Invisio G5 is the smallest Bluetooth headset in the world!
At least, for now. However, the Invisio has some cool features, like its one button on/off function. The whole kit comes with a power cable, as well as a charging station that looks like a cigarette box.
I'm not really sure how much it is, but is available now.
