Carbon is the first Bluetooth headset made of carbon fiber, and it weighs only 5.9 grams. Bluetrek designed the Carbon with Noiselock noise cancellation, a manual on/off switch, and multipoint technology so you can connect with two devices at once. Colored LEDs and voice alerts in three languages (English, Spanish, and Mandarin) indicate headset status. Simplified pairing means you don’t even need a pin code with many devices. It comes with four sizes of Erogobuds Advance tips and a microUSB cable for charging. The Carbon has a suggested retail price of $69.99 and can be purchased at the Bluetrek online store and at various retailers.
