The Bose Sport Open vs Ultra Open Earbuds (2nd Gen) decision is about how you listen: exercise first, or longer everyday sessions with extra audio features. Both are October 2026 releases. The Sport model here is the new clip-on design, not the old 2021 ear-hook earbuds.
Quick verdict: buy for the way you listen
Choose Sport Open for the less expensive Bose option focused on workouts. Choose Ultra Open (2nd Gen) if longer single-charge playback and spatial audio will matter beyond the gym. Skip both if you want to block out transport or office noise: neither has active noise cancellation.

The differences that change the decision
| Decision point | What changes |
|---|---|
| Workout protection | Sport Open: IP54 dust and splash resistance. Ultra Open 2: IPX4 splash resistance. Neither is for swimming. |
| Audio modes | Sport Open: stereo. Ultra Open 2: stereo plus Immersive Audio and Cinema Mode. |
| Phone compatibility | Both work over Bluetooth with Android and iPhone. Ultra adds aptX Adaptive on compatible Android devices; iPhone uses AAC. |
| Charging and devices | Both have USB-C and wireless case charging, physical controls and two-device Bluetooth multipoint. Paying more does not buy wireless charging alone. |
Bose launched Sport Open at US $199 and Ultra Open 2 at US $299 on October 1. That is a launch-price comparison, not a current Amazon offer. The better buy now depends on the actual price gap, not the premium badge.
Fit and sound: workouts or all-day listening?
Generated editorial illustration of listening situations; not a product photograph or a Decively listening test.
The exercise label does not guarantee a better fit on your ears. SoundGuys reviewer Dave Carr found the Sport cuff noticeable and one side less secure than the other; he liked the physical buttons but found volume adjustment fiddly. That is one reviewer’s experience, not a universal fit problem.
In a separate Ultra Open 2 review, Adam Birney found the cuff comfortable for several hours and compatible with sunglasses. He also heard stronger bass than the original Ultra Open. Neither impression proves that Ultra will fit every runner better.
Our buying take: Sport makes more sense for occasional workouts; Ultra earns consideration when you will also use its sound modes and longer playback at a desk. Open-ear listening lets outside sound mix with music. If you mostly listen in loud places, paying more for either model will not fix the lack of isolation.
Battery life: claims are not test results
| Decision point | What changes |
|---|---|
| Sport Open | Bose: up to 7 hours; up to 29 hours including case recharges. SoundGuys: 8 hours 5 minutes in its battery test. |
| Ultra Open 2 | Bose: up to 9 hours; up to 28.5 hours including case recharges. SoundGuys: 13 hours 1 minute in its battery test. |
These are separate reviews, not a Decively head-to-head test or a promise of your runtime. Loudness and settings matter. Bose lists only 3.9 hours for Sport Open with Auto Volume, while Ultra’s Immersive Audio modes reduce its claimed playback to about five hours.
The useful distinction: Ultra has the stronger single-charge claim, but Sport’s case-inclusive total is slightly higher. Do not compare one model’s case total with the other’s earbud-only figure.
Calls and software: know the limits
Both use Bose SpeechClarity processing, but the brand name is not proof of clear speech in wind. SoundGuys found wind troublesome in its microphone samples. Its Ultra review also warns that an artificial test head cannot reproduce the voice-pickup sensor’s behaviour on a person. Neither result justifies promising flawless outdoor calls.
Ultra’s Auto Volume also jumped too aggressively in Birney’s desk use. Try that feature cautiously rather than treating automatic adjustment as an automatic upgrade. Both use the Bose app for EQ, device management and updates.
Bose announced Google Find Hub, Alexa+ and an Apple Music shortcut for a later update. Check the installed firmware and regional availability before buying for those features; this comparison does not count the announcement as proof of availability.
Which one should you buy?
Sport Open: choose it when the cuff fits securely, workouts are the main use and its current price is meaningfully lower. You keep wireless charging and multipoint without paying for spatial modes.
Ultra Open 2: pay more for longer uninterrupted listening and audio features you will actually use. If you only need a short gym session, those extras may sit unused. Check the retailer’s policy for opened-earbud returns before relying on a home fit trial.
For the opposite approach—sealed earbuds that reduce background noise—see our AirPods Pro 3 vs Pro 2 comparison. For a portable workout setup, our beginner Garmin comparison explains when paying more changes daily use.
Research notes
Researched October 15, 2026. Decively has not tested either pair. Specifications and launch prices come from Bose; listening, fit and lab-test findings are attributed to the named reviewers. Their review units were supplied by Bose. New releases do not yet have reliable long-term ownership evidence.
