The Jabra Stone Bluetooth Earpiece

This is the first headset without a boom–the piece that extends from the ear to the mouth–giving it a more natural look. Instead of the meat of the headset being located behind the ear, or horizontally extending from the ear to the mouth in a boom, the Stone keeps all the circuitry in the earpiece that is curved and extends vertically up the ear and behind the lobe–making the whole unit seem smaller than usual.
