The Bose Ultra Open Earbuds are open-ear wireless earbuds designed to let you enjoy audio while staying connected to your surroundings [S1]. **Key Features** - **Audio Experience**: These earbuds feature 'Immersive Audio' for a spatial sound experience [S1]. They utilize OpenAudio technology to deliver high-quality private sound without blocking the ear canal [S1]. - **Design and Durability**: They feature a flexible, ultra-lightweight joint for a comfortable ear-hook fit [S1]. With an IPX4 rating, they are resistant to splashes, sweat, and rain [S1]. - **Battery Life**: The battery lasts up to 7.5 hours on a single charge, though this drops to 4.5 hours when Immersive Audio is enabled [S1]. The included charging case provides an additional 19.5 hours of playback [S1]. - **Connectivity**: They support Bluetooth multipoint for seamless switching between devices like phones and laptops [S1]. Bose SimpleSync technology also allows pairing with compatible Bose smart soundbars and speakers [S1]. **Considerations** As an open-ear design, these do not provide noise isolation.
