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 OpenRun Pro 2 and the Bose Ultra Open Earbuds (2nd Gen) made our Top 5 Open-Ear Earbuds for Running, at #1 (best overall) and #5. The most secure fit for running here: its wraparound band joins the two pods behind the head, so unlike the true wireless OpenFit 2+ and OpenFit Pro, neither side can fall out mid-stride, and TechRadar rated it the ideal runner's headphone. Bone conduction leaves the ear canal fully open, it is rated IP55, and its physical buttons and wind-resistant mics work on the move. It ranks above the OpenFit 2+ despite weaker bass (What Hi-Fi? found it lacks depth and punch) and no charging case, because for runners a fit that cannot fail matters more than sound. It is also the cheapest Shokz here. 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.
We score open-ear earbuds for running on Running Stability (25%), Sound Quality (20%), Sweat & Weather Resistance (15%), Battery & Charging (15%), Controls & Calls (10%) and Value (15%). On that basis the Shokz OpenRun Pro 2 totals 8.4 out of 10 and the Bose Ultra Open Earbuds (2nd Gen) 6.7. The widest gap is Running Stability, where the Shokz OpenRun Pro 2 scores 10 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. Sweat & Weather Resistance also separates them: 9 for the Shokz OpenRun Pro 2 versus 6 for the Bose Ultra Open Earbuds (2nd Gen). The Bose Ultra Open Earbuds (2nd Gen) claws back ground on Sound Quality.
