The Pillete can certainly lay claim to being the smallest Bluetooth headset in the world, if only it were not a concept. Coming in a pill-sized form factor, the Pillete features a high performance microphone that maintains optimal voice quality in a diminutive package. It is turned on whenever folded into a “L” shaped earbud and vice versa. I wonder if it fits comfortably with all ear sizes since some people have larger ear canals than the rest. For those who love pretty things, you can’t go wrong with the Pillete.
