This handmade, sterling silver ring from Analogue Aesthetics features a built-in microphone and a standard 3.5mm plug. Surely you can imagine the sort of fun that can be had with a device like this—plus, if a verbal jousting match with a heckler turned ugly, you have the satisfaction of knowing that a punch to the face with this baby on would be devastating. Available for $105. [Product Page via Boing Boing Gadgets]
