Bose Ultra Open Earbuds represent a revolutionary approach to personal audio, featuring innovative OpenAudio technology that delivers rich, immersive sound while keeping you aware of your surroundings. Unlike traditional in-ear earbuds that isolate you from ambient noise, the Bose Ultra Open Earbuds use a unique cuff-like clip-on design that rests comfortably on the outer ear, allowing environmental sounds to pass through naturally while projecting high-quality audio directly into your ear canal. This open-ear architecture is ideal for runners, cyclists, commuters, and anyone who values situational awareness without sacrificing audio performance.
OpenAudio Technology for Immersive Yet Aware Listening
The Bose Ultra Open Earbuds leverage proprietary OpenAudio technology to create a private listening zone that minimizes sound leakage while preserving environmental awareness. The custom-tuned drivers deliver balanced audio with clear highs, detailed mids, and surprisingly present bass for an open-ear design. Unlike standard open-ear speakers that sound distant or tinny, the Bose Ultra Open Earbuds position audio precisely for an intimate listening experience that feels personal yet non-isolating. Whether you are streaming music, taking calls, or listening to podcasts, the intelligent acoustic design ensures clarity and impact without blocking important ambient cues like traffic, announcements, or conversations.
Revolutionary Cuff-Like Clip-On Design for All-Day Comfort
The Bose Ultra Open Earbuds feature a flexible, cuff-inspired clip that gently secures to the outer ear without inserting into the ear canal. This innovative fit eliminates ear fatigue, pressure discomfort, and hygiene concerns associated with traditional in-ear designs. Each earbud weighs approximately 6 grams and measures 1.86 x 1.71 x 2.72 cm, making them lightweight and unobtrusive for extended wear
. The adjustable clip accommodates various ear shapes and sizes, ensuring a secure fit during movement, exercise, or daily activities. Unlike earbuds that require constant readjustment or cause discomfort after hours of use, the Bose Ultra Open Earbuds combine ergonomic engineering with premium materials for reliable, comfortable all-day performance.
Extended Battery Performance with Smart Power Management
Battery life is optimized for versatile use: enjoy up to 7.5 hours of continuous playback on a single charge with standard audio, or up to 4.5 hours when using Immersive Audio mode
. The compact charging case provides an additional 19.5 hours of playback, delivering a combined total of up to 27 hours of listening time
. On standby mode, the earbuds can last up to 48 hours without recharging, ensuring readiness when you need it most. Quick charging via USB-C restores approximately 2 hours of playback from just 20 minutes of charging. Unlike open-ear audio devices with limited battery capacity, the Bose Ultra Open Earbuds balance power efficiency with performance to support extended listening sessions.
Bluetooth 5.3 Connectivity and Immersive Audio Features
Powered by Bluetooth 5.3 technology, the Bose Ultra Open Earbuds ensure stable, low-latency wireless connection within an effective range of 10 meters. The earbuds support advanced audio profiles for reliable streaming and seamless device switching. Immersive Audio mode uses spatial processing to create a wider, more dimensional soundstage that enhances movies, music, and games
. Two dedicated microphones per earbud enable clear voice pickup for calls and voice assistant access. Unlike basic open-ear speakers with mono sound or limited connectivity, the Bose Ultra Open Earbuds deliver stereo audio with modern Bluetooth features for a premium wireless experience.
IPX4 Protection and Durable Premium Construction
With an IPX4 water-resistance rating, the Bose Ultra Open Earbuds withstand sweat, splashes, and light rain, making them ideal for workouts, outdoor activities, and unpredictable weather
. The refined construction features a combination of PC-ABS plastic, metal components, silicone contact points, and gold-plated connectors for durability and corrosion resistance
. The charging case measures 4.19 x 6.50 x 2.64 cm and weighs approximately 57 grams, compact enough for pocket or bag carry
. Unlike fragile open-ear audio devices that require careful handling, the Bose Ultra Open Earbuds combine rugged protection with premium materials for confident everyday use.
