Bose Ultra Open Wireless Earbuds, Lunar Blue

The Bose Ultra Open Earbuds are a true wireless model with an open-ear design, which means they do not insert into the ear canal. Instead, they attach to the outer ear, allowing the user to remain aware of their surroundings while listening to audio. The construction incorporates a flexible silicone joint and a lightweight body to provide a stable fit for extended periods. Audio is delivered via an open-back acoustic system supported by Digital Signal Processing. For connectivity, the earbuds utilize Bluetooth 5.3 to pair with compatible audio sources.

These earbuds offer up to 7 hours of listening time on a single charge, with the companion charging case extending the total playback duration to 24 hours. The case itself recharges in one hour via a USB-C connection and supports a fast-charge function. The earbuds are rated IPX4 for resistance to sweat and water splashes from any direction. Users can manage media playback and calls using the integrated button and touch controls. Further settings and customizations are available through the supporting Bose mobile application.
