Bose Frames Alto Audio Sunglasses – Bluetooth Wearable Speakers

Bose Frames Alto  integrates Bose acoustic engineering into a lightweight sunglass frame to produce open-ear directional audio that directs sound toward the wearer while minimizing leakage to bystanders. The frames house precision-tuned miniature speakers and digital signal processing (DSP) that emphasize voice clarity and midrange detail — making them particularly well suited for podcasts, calls, navigation prompts and casual listening without isolating you from ambient sounds. The product uses Bluetooth for wireless audio streaming and pairs with the Bose app for firmware updates and personalization.

Key Features:

• Open-ear directional audio — built-in mini speakers with DSP for private listening without ear cups. 

• Integrated microphone — hands-free calls and voice assistant support via the multi-function button.

• Bluetooth wireless streaming — reliable pairing and ~9 m (30 ft) nominal range.

• Battery & charging — up to 3.5 hours playback; typical full charge in ~2 hours.

• Lightweight frame — ~45 g for comfortable extended wear; available S/M and M/L sizes.

• UV protection lenses — black tinted lenses with UVA/UVB protection suitable for everyday outdoor use. 

• Companion app support — personalization, firmware updates and device controls through Bose mobile app.
