What are Bone Conduction Headphones?
It will change the way you think about audio.
Traditional headphones create sound waves that travel through the air and enter your ears, where your eardrums pick up the vibrations.
Bone Conduction is different - it sends vibrations into your skull bones, bypassing your eardrum, and transmits them directly to your inner ear, where the brain interprets them as sound.
