This attractive Sterling silver ring has as built-in microphone that can be used with a standard 3.5mm minijack plug. It gives new meaning to talk to the hand, right? Am I right here? What with the popular expression?
Is this thing on?
It's a custom jobber from Analogue Aesthetics and is available for sale on Etsy for $105. It's probably too bulky for some folk, but it's got a clean look that I like quite a bit.
