The Bose Ultra Open True Wireless Earbuds are designed to deliver rich, spatial sound while keeping your ears open to the world. With OpenAudio technology, they place sound in front of you even though the earbuds sit outside your ear canal—making ambient awareness possible. On a full charge, you get about 7.5 hours of playback, or about 4 hours if using the Immersive Audio mode. The included charging case offers an additional 19.5 hours, bringing total potential playback close to 27 hours. Their Bluetooth 5.3 connection ensures stable wireless communication, and a quick 10-minute charge gives up to 2 hours of use. Built for everyday wear, they have IPX4 splash resistance and a lightweight open-ear design that hooks gently over your ears for a secure fit.
