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

Open-ear earbuds have an obvious problem: ambient noise changes constantly, and manually reaching for volume every time a bus passes or a room quiets down gets tiring fast. Bose Ultra Open Earbuds Moonstone Blue handle it automatically — Auto Volume raises and lowers your music in response to what is happening around you.

Ultra Open Earbuds Moonstone Blue: Auto Volume: Set It Once

Traditional earbuds leave you riding the volume rocker all day — up on a busy street, down in a quiet office, up again on the train. Auto Volume watches the ambient level through the microphones and adjusts your playback to match, so your music stays audible without ever getting loud enough to isolate you from what is happening around you.

It is the single feature that makes an open design genuinely usable outdoors in a city, rather than something you keep turning up until it defeats the point of being open at all.

Bose Ultra Open Earbuds Moonstone Blue and Immersive Audio

Switch on Immersive Audio and the sound spatialises beyond the earbuds themselves, so music sounds like it is arriving from a wider space rather than sitting right at your ear. It is a genuinely different listening experience, and it is the reason battery drops from 7.5 hours to around 4.5 when it is running.

Because the earbuds have no seal at all, the effect works slightly differently than on sealed Bose earbuds — there is less isolation to begin with, so the spatial processing is layered onto an already-open soundscape rather than replacing silence.

Ultra Open Earbuds Moonstone Blue: Custom Button Shortcuts

The barrel on each earbud carries a button, and the Bose app lets you assign what a press and a long-press do — including Switch Source, which flips between two previously paired devices without removing the earbuds. Combined with multipoint, added in a July 2024 update, that covers most of what a working day needs.

Ultra Open Earbuds Moonstone Blue: Who Moonstone Blue Suits

Moonstone Blue is a pale, softly greyed blue that sits quietly on the ear without disappearing entirely — a middle ground between an anonymous black clip and a bold colour statement.

Being pale, it will show marks on the outer barrel sooner than black with heavy daily handling, though there is no eartip or cushion here to discolour from skin contact the way sealed earbuds have. A wipe keeps it looking new.

Ultra Open Earbuds Moonstone Blue: Comfort for All-Day Wear

The flexible joint and light clip mean these are genuinely comfortable for a full day, including through meals, calls and exercise, in a way sealed earbuds rarely manage. IPX4 covers sweat and splashes for workouts and unexpected rain.

FAQ – Ultra Open Earbuds Moonstone Blue

What does Auto Volume actually do

It adjusts your playback level automatically based on ambient noise, so you rarely need to touch the volume manually.

Does Immersive Audio work the same as on sealed Bose earbuds

The effect is similar but layered onto an open soundscape rather than an isolated one, since these have no seal at all.

Can I reassign the button

Yes, in the Bose app, including a Switch Source shortcut to flip between paired devices.

How comfortable are these for long wear?

Very. The lack of a seal or ear canal insertion is the main reason people choose this model over sealed alternatives for all-day use.

Is Moonstone Blue hard to spot if dropped?

Easier than black, though not as bright as Sunset Iridescent or Chilled Lilac.
