Design & Build Quality

The Bose Ultra Open Earbuds feature a distinctive cuff-like design that wraps around the ear but doesn't fully enclose it, providing both stability and comfort during extended use. The materials used are lightweight yet durable, with a smooth finish that feels premium to the touch. The open-ear design allows for ambient sound awareness without compromising on audio quality.

Performance

In real-world scenarios, these earbuds deliver impressive audio clarity and bass response, thanks to Bose's proprietary OpenAudio technology. Whether listening to music or taking calls, the sound is rich and clear, with minimal distortion even at high volumes. The open design ensures that users can hear their surroundings clearly, which is particularly useful for safety while walking or jogging.

Key Feature Analysis

The standout feature of these earbuds is the OpenAudio technology, which enhances audio quality in an open-ear setup. This feature works exceptionally well, providing a balanced sound profile that suits various music genres and voice calls equally well. The battery life, while good at up to 6 hours per charge, could benefit from improvements for more extended use without needing frequent recharges.

Battery Life

The earbuds offer a solid 6-hour battery life on a single charge and can be fully charged in their charging case, which provides an additional 24 hours of power. This is suitable for daily use but may require planning if you need continuous audio over several days without access to the charger.
