There are a lot of interesting gadgets out there, and one of them certainly is the Invisio Q7 Bluetooth headset. Designed to operate in loud environments, this headset picks up vibrations from your jaw when you are talking. This means there's no microphone to grab the sound you make!

The idea behind it is to use bone-conduction technology to convert your skull's vibrations into sound. It's apparently pretty comfy to wear as well, fitting in with the contours of your ear.

Expect the Invisio Q7 to hit the market sometime end of this year, retailing in at US $200.
