Credit: Bose The new Ultra Open earbuds come with three major upgrades over the previous generation: better battery life, better sound quality, and an improved design.

Battery life The first change is a welcome one; Bose upped the battery life from seven hours per charge to nine hours per charge.

For $299 open earbuds, most features should be at the top of the field, but the battery life was one notable area where the Bose earbuds lagged behind.

Now, they're on par with the Sony LinkBuds Clip .

Sound quality The second generation Ultra Open earbuds come packed with a new driver that addresses two areas where open earbuds commonly struggle: bass and volume.
