There are all sorts of cool headphones out there. Headsets feature Bluetooth, noise-cancellation, with designs that are over-ear, in-ear, wireless, water-poof, and so on. These headphones from FresheTech feature most of those features, plus one you don’t see very often: bone conduction.

You read that right. Meet the ALL-Terrain Bone Conduction Bluetooth Headphones. In addition to being tough, wireless, and water-resistant, they transmit sound to your inner ear through your skull instead of your eardrums. They ergonomically fit in front of your ears, meaning that you get high fidelity sound without blocking up your ears. So it’s ideal for situations where you want to tune into your music, shows or calls, but don’t want to tune out of the world around you. Additionally, their rubberized, water-resistant design is ideal for workouts. And of course they include all the track and call controls you’d expect from a modern headset.
