The differences between Tempo, Tenor and Soprano

Tempo is basically a pair of sports sunglasses. They are made of a thermoplastic material that can withstand extreme temperatures and various conditions. They also feature grippy nose pads, so they won’t slip down your face when you’re on the move. The Tempo has 22mm speakers embedded, and they are powerful enough to hear your music when you’re cycling at 25mph. Tempo also has eight hours of battery life, and has several lenses to choose from.  Including the basic polycarbonate one, Road Orange (can reduce glare from reflective surfaces), Trail Blue (can increase contrast under bright sun conditions) and Twilight Yellow (very low light lens for use at dusk).

Tenor and Soprano are pretty similar actually. And are made for everyday use. Tenor has a square-style design, and the Soprano have a subtle cat-eye shape. Both of these have 16mm speakers, so they are smaller than the Tempo. And are also scratch and shatter-resistant. Battery life is rated at 5.5 hours on these two. There are different lenses to choose from as well. Including Mirrored Blue and Silver for Tenor. While Soprano has Rose Gold and Purple-fade.

These are pretty neat looking sunglasses from Bose and while they are not cheap, they are a pretty interesting product. Instead of needing to bring headphones with you on a jog, you can just bring your sunglasses. And with eight hours of battery life, the Tempo will last a full run.
