Experience high-quality sound — without headphones. That’s the magic of Bose Frames Tempo: high-performance sport sunglasses with a revolutionary Bose Open Ear Audio™ design that allows you to hear your music and your surroundings at the same time for a workout unlike any other. Two specially designed Bose speakers embedded in the temples produce sound that’s louder and deeper than other audio sunglasses while the Open Ear Audio™ design (nothing in or on your ears) frees you from headphones so you can stay aware of your surroundings — traffic, pedestrians, whatever you run up against when exercising outside. With a sweat- and weather-resistant design, a lightweight, aerodynamic nylon frame, and soft, silicone nose pads (three options included for the best fit), Bose sport sunglasses are designed for comfort and performance. The scratch- and shatter-resistant polarized lenses have a VLT of 12%, ideal for most sports. Plus, they’re interchangeable. Bose sport sunglasses play up to eight hours at a time. Include an advanced mic system for clearer calls. It’s the sound you expect from Bose with everything you need from sport sunglasses. Specially designed for trail running and mountain biking, Trail Blue interchangeable sport lenses sharpen details in uneven terrain while reducing bright light. Polarized to reduce glare with extended length for extra protection.
