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

Bose Ultra Open Earbuds Black do not go in your ear canal at all. They clip around the lower ear like a piece of jewellery, leaving the canal completely open, which means you hear your music and everything around you at the same time — traffic, a colleague, your own footsteps.

A Cuff, Not a Plug

The shape is a U: a soft arc sits within the outer ear and a small barrel hangs just outside it, connected by a flexible joint. There is no tip, no seal, nothing pushed into the canal. Bose designed it explicitly to leave room for an earring and to disappear the way ear cuff jewellery does.

That is also why these suit people who find sealed earbuds physically uncomfortable, or who simply do not want their ear canal blocked for eight hours of a working day.

Bose Ultra Open Earbuds Black: How OpenAudio Avoids Leaking

Open-design earbuds have a reputation for being audible to everyone standing nearby, because there is no seal to contain the sound. Bose built OpenAudio specifically to fight that: a directional transducer and a tightly controlled acoustic path aim the sound at your ear canal rather than broadcasting it outward.

The result is genuinely surprising the first time you hand them to someone else — even at a fairly high volume, a person a foot away hears very little. It is not silent, but it is far quieter than the open design would suggest.

Ultra Open Earbuds Black: Why There Is No Noise Cancelling

We would rather say this plainly than let it be a surprise. There is no active noise cancellation here, and there cannot be — ANC requires a seal to work against, and these are built to have none. If you want cancellation, the QuietComfort or QuietComfort Ultra Earbuds are the right choice instead.

What you get in exchange is constant situational awareness: running near traffic, working in an office where you need to hear your name, or cycling where hearing a car matters more than isolation.

Who Ultra Open Earbuds Black Suits

Ultra Open Earbuds Black is the version that reads as understated jewellery rather than as visible tech, which suits an office or a formal setting where a chunky earbud might draw comment. It also hides scuffs on the clip better than any pale finish.

The trade-off is the usual one: black is harder to spot if it comes loose during a run. Moonstone Blue, Lunar Blue, Chilled Lilac and Sunset Iridescent are all easier to locate, with identical hardware.

Ultra Open Earbuds Black Battery, Standby and the Case

Up to 7.5 hours per charge, dropping to about 4.5 with Immersive Audio spatialising the sound. Standby reaches up to 48 hours, so leaving them clipped on and connected all day between short listening bursts does not drain them the way continuous playback would.

The case adds up to 19.5 further hours (12 with Immersive Audio), charges the buds fully in about an hour, and a 10-minute burst returns roughly two hours of playback. Full detail is on the official Bose Ultra Open Earbuds page.

FAQ – Bose Ultra Open Earbuds Black

Can other people hear my music?

Not usually. OpenAudio directs sound into your ear canal with minimal leakage, so someone standing close hears very little even at moderate volume.

Is there any noise cancellation?

No. The open design has no seal for ANC to work against. Choose the QuietComfort Ultra Earbuds if cancellation matters to you.

Will they fall out while running?

Ultra Open Earbuds Black uses a flexible clip designed to stay put during movement, and the fit sits securely around the lower ear rather than relying on a seal.

Do they connect to two devices?

Yes, multipoint was added via a software update in July 2024, provided the earbuds are kept updated in the Bose app.

Can I wear an earring with Ultra Open Earbuds Black?

Yes. The clip design deliberately leaves room for one.

Does Totot deliver across the UAE?

Yes. We ship nationwide via Aramex for a fixed AED 10, with cash on delivery, Tabby and Tamara available at checkout.
