Combining music listening with a variety of sporting activities is an expression of contemporary zeitgeist. The Bose Frames Tempo deliver the experience of high-quality sound without the need of headphones. The sport audio sunglasses with their innovative Bose Open Ear Audio design allow people to listen to music and hearing their surroundings at the same time. The aim of their design was to combine the aspects of comfort and performance in such a manner that no compromises had to be made. The sunglasses are lightweight, feature a nylon frame of aerodynamic appearance and are equipped with soft silicone nose pads. The glasses fit securely and are sweat and weather resistant. With specially designed speakers, one embedded in each temple, these glasses play louder and deeper than comparable audio sunglasses. It gives users the special experience of being able to hear and feel the music, even over the rush of the wind when cycling at speeds of 40 km/h. The Bose Frames Tempo connect seamlessly to mobile devices via Bluetooth. The volume is easy to control through simple forward/backward swipe gestures on the side of the right temple. Moreover, users can also intuitively toggle between streaming music and receiving a phone call via a single button on the frame – without having to take out the phone.
