Bose Ultra Open Earbuds Lunar Blue pair a deep, muted blue with the open-ear cuff that made this model different. Lunar Blue is one of the colours Bose added after the original Black and White Smoke launch in February 2024. Nothing goes into the ear canal: the speaker sits at the opening and the battery rests behind the ear, so on an early-morning run along the corniche you still hear a car pulling out, a cyclist behind you or a friend calling your pace. For outdoor training, that awareness is the main reason to choose an open design.

Running and hearing the road
Sealed earbuds and roads do not mix well: block the outside and you miss the sounds that keep you safe. Bose Ultra Open Earbuds Lunar Blue leave the canal open, so traffic, footsteps and voices reach you while your playlist runs. Turn on Auto Volume in the Bose app and the level rises when a busy road gets louder, then drops when you turn into a quiet street, so you are not reaching for the button mid-stride. Your own breathing and footfall also sound natural, without the thumping you get from sealed tips.
Why the cuff stays put mid-stride
Sealed earbuds stay in by friction inside the canal, which sweat and jaw movement can loosen. Here a flexible arm coated in soft silicone wraps the outer ear and links the speaker head to the battery barrel, so the grip comes from the shape, not from a tip. Each bud weighs about 6 g, light enough not to bounce. Bose says the design works alongside sports sunglasses and caps, the usual kit for running outdoors in the UAE sun.
IPX4 and summer training
Bose rates Bose Ultra Open Earbuds Lunar Blue at IPX4, which covers sweat and splashing water. That is enough for hot runs, gym sessions and a sudden shower, but not for swimming or rinsing under a tap. After a sweaty session, wipe the silicone arm and the speaker opening with a dry cloth and let the buds dry before closing the case. The case charges over USB-C, and 10 minutes inside gives roughly two hours of playback, useful if you forget to charge before heading out.
Who Lunar Blue suits
Lunar Blue is for runners and walkers who want something less formal than Black but not as bright as a pastel. The muted blue sits well with navy, grey and black training gear and looks calm against both dark and light hair. It also helps in practice: a blue bud is easier to spot on grass or a gym floor than a black one. If your training kit is mostly dark, Bose Ultra Open Earbuds Lunar Blue add a little colour without clashing.
The rest, in brief
OpenAudio aims sound at your ear and limits leakage; Immersive Audio offers Still and Motion modes. Bose quotes up to 7.5 hours per charge with Immersive Audio off and about 4.5 hours with it on (75 dBA test), plus up to 19.5 hours from the case, or 12 with Immersive Audio. A full charge takes about an hour, standby lasts up to 48 hours. Bluetooth 5.3, multipoint since July 2024, Google Fast Pair, aptX Adaptive with Snapdragon Sound phones, and AAC or SBC otherwise.
Who This Is Not For
Bose Ultra Open Earbuds Lunar Blue are not for swimmers or triathletes: IPX4 covers sweat and splashes only. There is no noise cancelling, so they will not quiet a gym full of loud music or a flight. Bass is lighter than sealed earbuds, and Immersive Audio cuts playback to about 4.5 hours, short for an ultramarathon. The box has no power adapter, and Bose lists USB-C charging only for the case.
