Invisio Q7 Bluetooth headset

Get your message across clearly with the Invisio Q7 Bluetooth headset without raising your voice to drown out the noise around you while talking on the cellphone. This is made possible as the Q7 uses bone-conduction technology to convert your skull’s vibrations into sound, making you sound crystal clear even though you’re in front of huge stage speakers at the Rolling Stones’ concert. The Q7 is comfortable to wear as it fits inside your ear snugly. Expect working models to be released by the end of this year for $200 at RadioShack.
