The WPPL Bone Conduction headphones do not go directly into your ear canal, but rest on your cheekbones. This allows you to safely hear the environment around you.

When you play music, the sound vibrations are conducted by the speakers through your bones to the cochlea. There, the vibrations are passed on to
the auditory nerves, where they are ultimately processed in your brain. With Bone Conduction earplugs, your eardrums are completely ignored.
