Nextlink certainly isn't the first company to boast about having the "world's smallest Bluetooth headset," but judging by some quick math, its Invisio G5 may actually be the most diminutive -- for the moment, at least. Measuring in at just 3.3- x 1.6-centimeters and weighing less than six grams, this wee earpiece has an abnormally high risk of vanishing, but at least it will last through some 20-hours of yapping if you do manage to keep track of it. The unit also comes with a protective charging case, and the Soft Spring technology purportedly enables it to "adapt perfectly to the contours of the ear." There's no definitive word on pricing nor availability, but a brief search revealed that this thing can be had for around a C-note at a variety of online stores.
