Kyocera's Smart Sonic receiver and tissue conduction technology have been around for some time, but this year at MWC, we had another chance to test it out. In case you didn't know, the receiver's a ceramic piezoelectric actuator that takes the place of a phone's speaker to let listeners hear phone calls in even the loudest environments. We got to test it out with a Kyocera Torque, and well... trust us, you'll want to see (and hear) the results in the video after the break.
