Bose Sport Open Earbuds vs Ultra Open Earbuds (2nd Gen): Which Should You Buy?

Bose's newest open-ear earbuds go on sale in Australia tomorrow, 01/10/2026, and this time there are two of them, built for genuinely different people. The Bose Sport Open Earbuds and the Bose Ultra Open Earbuds (2nd Gen) both land at Bose's own store and audio retailers around the country this week, priced at AU$349.95 and AU$449.95 respectively. If you've been eyeing off the open-ear category but weren't sure which version made sense for you, here's the actual difference.

Open-ear earbuds sit just outside the ear canal rather than plugging it, using a small speaker held in place by a soft cuff or hook. You get music or calls in one ear and the world in the other, which is the entire appeal: no isolation, no missed traffic, no ripping a bud out to hear someone talk to you. Bose more or less created the mainstream version of this category with the original Ultra Open Earbuds, and it's now splitting the line in two rather than releasing a single do-everything model.

Bose Sport Open Earbuds: built for the gym, not the couch

At AU$349.95, the Sport Open Earbuds are the cheaper and more purpose-built of the two. The C-arm cuff design uses a soft, matte silicone finish and sits noticeably lighter than the Ultra model, which matters once you're an hour into a run and forgetting they're there is the whole point. They carry an IP54 rating for sweat, splash and dust resistance, have physical tactile controls you can find without looking (a genuine advantage mid-workout over a touch surface), and Bose's Auto Volume feature adjusts playback automatically as ambient noise changes, so you're not fumbling with volume on a busy street.

Battery life is rated at up to 7 hours per charge, with a further 22 hours available from the compact wireless charging case, giving the Sport model the longer total runtime of the pair once the case is factored in. They come in Black, White Smoke and a limited-edition Eucalyptus Green, and use custom-designed dynamic drivers paired with Bose's SpeechClarity technology for clearer calls when you're out and moving. This is the pick for runners, cyclists and anyone whose earbuds mainly need to survive a workout, not soundtrack a Sunday afternoon.

Bose Ultra Open Earbuds (2nd Gen): the everyday upgrade

The second-generation Ultra Open Earbuds are the more premium, all-round option at AU$449.95. The cuff has been refined with a metallic cap and beveled finish, and Bose has fitted a newly engineered driver that delivers noticeably deeper bass than the outgoing model, a real weak point of the original Ultra Open design. Bluetooth 5.4 now supports multipoint connectivity across two devices at once, and the earbuds add Snapdragon Sound with aptX Adaptive for higher-quality wireless audio on supported phones.

The standout addition is Cinema Mode, built on Bose's TrueSpatial technology, which widens the soundstage for video and podcasts to feel more immersive than a typical pair of open-ear buds. Battery life sits at up to 9 hours per charge with a further 19.5 hours from the case, and colour options stretch to Black, White Smoke and limited-edition Cherry Chocolate, Olive Green and Sky Pink finishes. A firmware update after launch will add Google Find Hub, Alexa+ and an Apple Music shortcut. This is the model built for everyday wear, commuting, calls and general listening rather than sport specifically.

Which one should you actually buy?

If your earbuds mainly come out for a run, ride or gym session, the Sport Open Earbuds are the better-built and cheaper tool for that specific job, and the IP54 rating and tactile controls genuinely earn their keep there. If you want one pair of open-ear buds for calls, commuting, podcasts and the odd workout, the Ultra Open Earbuds (2nd Gen) justify their extra AU$100 with better sound, Cinema Mode and multipoint connectivity.

At a glance:

• Bose Sport Open Earbuds: AU$349.95, up to 7 hours battery (+22 hours case), IP54 rated, Black / White Smoke / limited Eucalyptus Green
• Bose Ultra Open Earbuds (2nd Gen): AU$449.95, up to 9 hours battery (+19.5 hours case), Cinema Mode spatial audio, deeper bass driver, multipoint Bluetooth 5.4
• Both: OpenAudio technology, SpeechClarity call tech, wireless charging case, on sale in Australia from 01/10/2026

Verdict: These aren't two versions of the same product, they're two different answers to the same open-ear idea. Buy the Sport Open Earbuds if you're an athlete who wants lightweight, sweatproof buds that stay put and don't cost you AU$450. Buy the Ultra Open Earbuds (2nd Gen) if you want the best all-round open-ear sound Bose makes and will actually use Cinema Mode and multipoint day to day. Either way, both are worth a look the moment they land in stores tomorrow, because nobody else in the open-ear space is offering this much choice at these price points.
