The thing that makes the AfterShokz stand out is the "Bone Conduction" technology. They Bluez 2 don't fit in your ears - or over your ears. They sit in front of your ears - on your cheekbones and then conduct the sound (vibrations) generated by the transducers inside your head - while leaving your ears open. The beauty is that you can not only listen to music, movies, audiobooks, podcasts and phone calls, you can also still hear the world around you...
