Should you buy it?
Buy the Ultra Open Earbuds (2nd Gen) if you want earbuds you can wear all day and still hear traffic and coworkers; Bose claims deeper bass and more volume than the original, 9 hours of playback and 19.5 more from a case that now charges wirelessly. Skip them if you ride loud trains, because the open design has no noise canceling at all. Battery falls to 5 hours with Immersive Audio or Auto Volume on and 4 hours with both (Bose claim), and aptX Adaptive works only on Snapdragon Sound Android phones. At $299 (on sale Oct 1, 2026) they cost $100 more than Bose's new Sport Open Earbuds, and independent lab tests aren't out yet.
