AfterShokz showcased headphones for the fitness, mobile and gaming markets that leverage bone-conduction technology to transmit sound through the listener's cheekbones to the inner ear. Unlike ear buds, the headphones sit in front of the ear and bypass the eardrum, which the company contends means a safer transmission of sound. "Bone-conduction technology has been around a long time, developed initially for our military forces," said Bruce Borenstein, president and CEO of AfterShokz. "We've taken that technology and built it into consumer-friendly headphones that active adults, business travelers and gamers will benefit from." The company offers three models -- AfterShokz Sport, AfterShokz Mobile and AfterShokz Game.
