piece of gadgetry made its way through the FCC last week, we didn't have a whole lot of details to share about the "world's first carbon fiber Bluetooth headset." Well, Bluetrek's making the Carbon official today with a $70 price tag and a full set of specs. The thing weighs in at a mere .25 ounces, touts Bluetooth v3.0 support, and allows for four and a half hours of talk time or five days on standby. It also comes with a set of four earbuds in different sizes, so anyone can rock the lightweight headset no matter how big, or small, the ear hole. The Carbon is now on sale at the source link below. Full PR after the break.
