Bluetrek and Contour Design jointly present the thinnest Metallic Bluetooth 2.0 earpiece for cellphones, including the iPhone. A strange amalgamation of style and class, this downy and sleek headset is just 4.3 mm wide and weighs 5.5 grams only. Having a real impressive silver aluminum body, accented by chrome, it also touts a belt clip, six rubber ear tips, two optional clear plastic ear mounts, a car charging bulb and a USB extension cable. Other features include one touch answer, integral volume control and 5 hours of talk time with 7 days’ standby. This hands-free accessory sells for $80; a bit pricey indeed!
