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 ergonomic, lightweight design (approx. 5.8g per earbud) uses soft silicone ear hooks and a secure-fit wing for stability during movement. Each earbud houses a custom-tuned transducer with advanced acoustic tuning for balanced audio, while the charging case offers up to 6 hours of playback (with 24+ total via case). IPX4 water resistance ensures protection against sweat and light rain. Included: USB-C charging cable, quick-start guide, and support card. The minimalist white finish complements modern tech aesthetics, and intuitive touch controls enable seamless playback, call handling, and voice assistant access. Perfect for professionals, fitness enthusiasts, and urban commuters seeking high-fidelity audio without isolation.
