How they differ in real use
Built from our open ear earbuds for running scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Shokz OpenFit Pro and the Bose Ultra Open Earbuds (2nd Gen) made our Top 5 Open-Ear Earbuds for Running, at #3 (best premium) and #5. The best-sounding Shokz and the only pick with open-ear noise reduction, which helps on a loud treadmill or gym floor while keeping you aware of traffic outdoors. UltraRunning found it secure on trails, and its 12 hours (50 with the case), IP55, Bluetooth 6.1 and triple mics match or beat the OpenFit 2+. It ranks below the OpenFit 2+ because reviewers found the noise reduction modest, switching it on halves battery life to 6 hours, and it costs more. It ranks above the AeroFit 2 and Bose on fit security, call quality and sweat rating. The newest pick (on sale October 1, 2026) and the best for sound away from the run: Gizmodo called it a clear step up from the original, with deeper bass, TrueSpatial head-tracked audio and a tighter clip. It ranks last for running because its IPX4 rating is the lowest here (every other pick is IP55), Bose markets it for travel and office rather than training, and a clip-on cuff is less locked-in than the Shokz hooks or the OpenRun band. It is also the most expensive pick. Choose it over the AeroFit 2 only if your runs are easy and sound quality comes first.

The widest gap is Running Stability, where the Shokz OpenFit Pro scores 8 against 6 for the Bose Ultra Open Earbuds (2nd Gen): how securely the design stays put at running pace (wraparound band, ear hook or clip, and whether the hook adjusts), based on reviewers' running and workout reports.
