Open-ear earbuds
Bose's first clip-on open-ear earbuds, which cuff onto the side of the ear and leave the ear canal open, with head-tracked Immersive Audio and aptX Adaptive on compatible Android phones. The case has no wireless charging.

Cuff design
A silicone-coated flex arm clips each earbud to the edge of the ear, clear of glasses, hats and earrings. Reviewers found them comfortable for hours, though finding the right position can take a few tries.

Little sound leakage
Reviewers found the sound rich for open earbuds and heard little leakage at normal volumes. Music gets harder to hear in loud places such as busy streets or trains.

Immersive Audio
Head-tracked Immersive Audio keeps sound fixed in place or in front of you as you move, with any source. Turning it on cuts each charge from a rated 7.5 hours to 4.5 hours.
