Bose Frames Alto Audio Sunglasses S/M – Bluetooth Audio

Bose Frames Alto integrate miniature 16 mm dynamic transducers into the temple housings to deliver perceptible low-end and articulate midrange while maintaining an open-ear listening experience. Unlike bone-conduction approaches, the Alto drivers reproduce a fuller tonal balance while minimizing sound leakage to the surrounding environment. The on-frame acoustic chambers are tuned to provide intelligible playback at practical listening levels without occluding ambient sound — preserving situational awareness for urban use and active lifestyle scenarios.
