"Air conduction" might sound like a Pokemon move, but it is also how you can listen to your music. The All-Terrain Bone Conduction Bluetooth Headphones deliver sound directly to your inner ear by vibrating the bones in your skull. This bypasses the eardrums without blocking your normal hearing, meaning you can still be fully alert while jamming out. They're wireless, water-resistant, and did we mention they work by vibrating your head bones? Normally, this incredible technology would cost you $149.95, but right now you can get the All-Terrain Bone Conduction Bluetooth Headphones for just $60, a 59 percent discount.
