Bose Ultra Open Earbuds, Immersive OpenAudio Earbuds for Running & Awareness, Clip-On Comfort, 48H Battery Life, Lunar Blue

Sealed earbuds and running have an old conflict: isolate the outside world and you cannot hear traffic, a cyclist’s bell, or someone calling your name. Bose Ultra Open Earbuds Lunar Blue were built for exactly this problem — the open design means full environmental awareness while you train, with no compromise on either side.

Ultra Open Earbuds Lunar Blue: Built for Roads, Not Just Rooms

On the Bose Ultra Open Earbuds, running with music while genuinely hearing traffic is the specific use case Bose built this model to solve. Because nothing seals the ear canal, road noise, other runners and verbal warnings all reach you at full clarity — the open design is a safety feature as much as a comfort one for anyone training outdoors.

On the Bose Ultra Open Earbuds, auto Volume raises your playback over passing traffic and drops it again once you turn onto a quiet street, so you are not constantly reaching for a button mid-stride.

Bose Ultra Open Earbuds Lunar Blue and Staying Put

On the Bose Ultra Open Earbuds, the flexible clip hooks around the lower ear rather than relying on a plug staying wedged in the canal, which is a fundamentally different failure mode from sealed earbuds. There is no tip to work loose from sweat or motion — the joint itself provides the grip.

On the Bose Ultra Open Earbuds, reviewers have consistently noted the fit as secure through running and general movement, which is the entire premise the design has to deliver on.

Ultra Open Earbuds Lunar Blue: IPX4 and Real Workouts

On the Bose Ultra Open Earbuds, iPX4 covers sweat and splashing rain from any direction, with acoustic mesh over the ports keeping moisture and debris out of the internals. That covers a genuine training session, though not a swim.

Full waterproofing detail and the complete spec sheet are on the official Bose Ultra Open Earbuds page.

Ultra Open Earbuds Lunar Blue: Who Lunar Blue Suits

On the Bose Ultra Open Earbuds, lunar Blue is a mid-tone, slightly hazy blue that reads as sporty without being loud, which fits the training use case this model is built around. It sits between the anonymity of black and the brightness of Sunset Iridescent.

On the Bose Ultra Open Earbuds, being a mid-tone rather than pale, it hides the marks that outdoor use and sweat inevitably leave better than the lighter colours in the range do.

Ultra Open Earbuds Lunar Blue: Battery for a Long Session

On the Bose Ultra Open Earbuds, up to 7.5 hours covers a genuinely long training block or a full working day of intermittent listening, dropping to about 4.5 with Immersive Audio active. The case adds up to 19.5 further hours, and a 10-minute emergency charge returns roughly two hours — enough for one more session before you are near a charger again.
