The Bose Ultra Open Earbuds are a unique audio wearable designed as a "cuff" that clips onto the outer edge of your ear rather than sitting inside the canal. This open-ear design allows you to remain fully aware of your surroundings while proprietary OpenAudio technology directs sound privately into your ear.

Key Features and Performance
Design and Comfort: Resembling ear cuff jewelry, the earbuds use a flexible silicone arm to stay secure. Experts at TechGearLab and Mashable have called them some of the most comfortable earbuds ever tested, often being forgotten during all-day wear.
Audio Quality: Despite the open design, they offer rich sound and a surprisingly weighted bass for the category. They also feature Immersive Audio for a spatialized 3D effect.
Battery Life: You get up to 7.5 hours of play time on a single charge (reduced to 4.5 hours with Immersive Audio) and up to 48 hours of standby.
Situational Awareness: Because they do not block the ear, they are ideal for runners, cyclists, or office workers who need to hear ambient sounds like traffic or colleagues.
Durability: They carry an IPX4 rating, making them resistant to sweat and light rain.
