Our Verdict

Bose Ultra Open Earbuds

Bose Ultra Open Earbuds (2nd Gen)

The Bose Ultra Open Earbuds (2nd Gen) are a slight improvement on the original Bose Ultra Open Earbuds. Both have comfortable, exceptionally stable ear-cuff designs that let you stay aware of your environment, but neither delivers much bass or blocks outside noise. The biggest improvement with the 2nd Gen is battery life: they now last 13 hours per charge compared with the original's 9.5 hours. The newer model also supports wireless charging directly through its case, whereas the original case charges only via USB-C. You also get some additional listening features like automatic volume adjustment, which adjusts your audio based on the level of noise around you. Still, if you're mainly interested in the comfortable open-ear fit, the first generation are still a great choice.
