Bose Ultra Open Earbuds are premium open-ear wireless earbuds designed for situational awareness and all-day comfort. Featuring Bose’s proprietary OpenAudio™ technology, they deliver rich, immersive sound without sealing the ear canal—ideal for outdoor activities, commuting, or office use where ambient awareness is essential. The sleek, lightweight black chassis (only 5.4g per earbud) uses ergonomic wingtips for secure fit during movement, while IPX4 sweat/water resistance ensures durability. Active Noise Cancellation is not included (by design), but Adaptive EQ automatically optimizes audio based on ear shape and fit. The compact charging case features USB-C fast charging (2 hours playback from 15-min charge) and displays battery status via LED. Includes multiple ear tip sizes and a quick-start guide. Perfect for professionals, fitness enthusiasts, and urban commuters who value safety, clarity, and minimalist design without compromising audio quality. Compatible with iOS and Android via Bluetooth 5.3 with multipoint support.
