The Tempo (see image above) is a pair of sports sunglasses made from TR90, a thermoplastic material that can withstand extreme temperatures and various conditions. It also has grippy nose pads to keep the glasses from sliding over your face while driving. This model has 22mm speakers embedded in the brackets. They should be so powerful that you can still hear what you are hearing even when cycling at 40 km / h.
In addition, the Tempo is USB-C compatible, has a battery life of eight hours and a choice of several lenses with different advantages: the basic polycarbonate Road Orange (can reduce glare from reflective surfaces) and Trail Blue (can increase contrast) under bright sun conditions) and Twilight Yellow (lens with very little light for use at dusk).
Meanwhile, both tenor and soprano have been made for everyday use, with the former having a square design and the latter having a subtle cat-eye shape. Both have 16 mm speakers, are scratch and shatterproof and have a battery life of 5.5 hours. You also have several lenses to choose from: Mirrored Blue and Silver for Tenor, Rose Gold and Purple-Fade for Soprano.
All three models require a prescription and are available now for $ 249.95 from Bose and select resellers.
