Our Verdict
Bose Ultra Open Earbuds
Shokz OpenFit Air
The Bose Ultra Open Earbuds are better open-fit workout earbuds than the Shokz OpenFit Air. The Bose are more comfortable and stable and their continuous battery life is three hours longer. That said, the Bose are much more expensive than the Shokz, and they don't support multi-device pairing.
