“Most headphones block out all exterior noise, allowing you to become fully immersed in your music. But AfterShokz aren’t like most headphones.
They use bone-conduction technology to transmit audio waves to the inner ear through the skull, bypassing the eardrum completely. You place them on your cheekbones, just in front of your ears. Your ear canals stay open, letting you retain full use of your ears and remain alert and aware of ambient sounds while you also enjoy your tunes.”
