Bose Frames Alto Audio Sunglasses M/L – Black

Bose Frames Alto (M/L) are precision-engineered audio sunglasses that integrate Bose acoustic technology into a refined, classic angular frame. The design houses miniaturized drivers and patented acoustic chambers inside the temple arms to deliver directional, open-ear audio—providing immersive sound to the wearer while minimizing leakage to people nearby. This open-ear approach preserves situational awareness for outdoor use (cycling, commuting, walking) while delivering clear vocals and balanced midrange response characteristic of Bose tuning.
