Aftershokz Air Green

With the AfterShokz Air, you have complete freedom of movement during your workout. These Bone Conduction earbuds aren't inside your ear, but on your cheekbones. The sound is sent to your brains via vibrations. That way, your ears aren't closed off from ambient noise. This is extra safe when you're in traffic. Because the earbuds are water-resistant, you can listen to music during your workout. They won't break down from sweat or rain.

Note: these earbuds are less suitable for phone calls.

Bone conduction earbuds don't go directly into your ear canal, but rest on your cheekbones. That way, your eardrums aren't involved. The vibrations of the music go to your auricle via your bones, where the vibrations are sent to the auditory nerves and end up in your brains.
