Bose Frames Tempo
Designed for sports. Engineered for sound.
Experience high-quality sound — without headphones. Bose Frames Tempo are high-performance sport sunglasses with a revolutionary Bose OpenAudio design that allows you to hear your music and your surroundings at the same time for a workout unlike any other.
Nothing in or on your ears.
A revolutionary Bose OpenAudio design frees you from headphones so you can stay aware of traffic, pedestrians, or whatever else you’re up against when exercising in the great outdoors. And with two specially designed Bose speakers, Bose Frames Tempo style play louder and deeper than other audio sunglasses — loud enough to hear your music over the rush of the wind when cycling at speeds of 40 km/h.
