Bone Conduction technology combined with the convenience of Bluetooth headsets gives form to Sonic Shades. A true open-ear experience, these shades allow you to play music, listen to audiobooks or simply take calls, all while having your ears open to nature, traffic, and conversation. With a battery life of 8 hours and intuitive touch-based controls, Sonic Shades works with most modern Bluetooth devices. To top it all off, the UV400 Polarized Anti-Glare lenses ensure strain-free comfortable vision.
