QuietComfort Ultra Earbuds (2nd Gen) offer all the same features as their predecessor, QuietComfort Ultra Earbuds, plus:

  • Improved call quality through AI-based background noise suppression
  • Wireless charging
  • Improved ActiveSense (adaptive noise cancellation) technology
  • Case battery level reporting in the Bose app
  • Option to disable touch controls via the Bose app

Cinema Mode is a preset mode that utilizes Bose TrueSpatial technology to transform stereo audio into theater-like, immersive sound for a cinematic experience.

SpeechClarity is an AI-based, proprietary technology that filters out your surroundings and wind so you can be heard clearly on phone and video calls.

ActiveSense is a type of adaptive Aware Mode that listens for very loud environmental sounds and selectively applies noise cancellation appropriate for both the loudness and duration of the detected sound. This way, you can remain aware of your surroundings without having your music drowned out by interruptions like passing vehicles and loud appliance motor noises, such as a coffee grinder or blender. With this update of ActiveSense, the experience is refined so the changes in noise cancellation levels are less noticeable, contributing to an overall smoother adaptive Aware Mode experience. ActiveSense can be enabled and disabled in the Aware Mode setting.

Immersive Audio allows you to hear audio as if it were coming from beyond your QuietComfort Ultra Earbuds (2nd Gen), thereby allowing for a more spacious, natural listening experience. Your music and other audio will have a wide sound stage in front and to the sides, just as if you were listening to a pair of stereo speakers and seated at the sweet spot between them.

Bose CustomTune audio calibration is a proprietary Bose technology that optimizes the audio playback you hear based on the unique physical properties of your ear and ear canal. It works by playing a specially designed calibration tone as the welcome chime each time you power on the earbuds while wearing them. It then measures how the shape of your ear uniquely modifies that sound. The earbuds use that information to adjust their sound to your ears, creating a more balanced, authentic audio experience.

Bose QuietComfort Ultra Earbuds (2nd Gen) utilize both passive and active noise reduction technologies. Passive noise reduction is similar to when you wear earplugs; there is a physical blockage preventing some of the sound from entering your ear. This is achieved through the earbud design with materials such as silicone eartips, and the acoustic seal created by having a proper fit. For active noise cancellation, your earbuds use sophisticated proprietary electronics with microphones both inside and outside the earbuds. The electronics system senses the sound in almost any environment and then measures, compares, and reacts — instant by instant — to produce an opposing cancellation signal.

The left and right earbud surfaces are the same, but the controls vary depending on whether you are listening to audio or on a phone call.

When listening to audio:

  • Swipe up or down for volume control
  • Tap once to play or pause content
  • Tap twice in quick succession to skip forward
  • Tap three times in quick succession to skip back
  • Press and hold the earbud surface to access a favorite listening mode, and release when the desired mode is announced. The default shortcut function on both buds is to cycle through three listening modes:
    • Quiet Mode (full noise cancelling)
    • Aware Mode (full audio transparency to hear outside sound)
    • Immersion (full noise cancellation with Immersive Audio)
  • You can create additional modes or remove modes you don’t want using the Bose app.


For phone calls:

  • Swipe up or down for volume control
  • Tap once to accept an incoming call; if you are already on a call and a second call is coming in, tap once to accept the second call and place the first call on hold
  • Tap twice in quick succession to decline a call, to end a call already in progress, or to decline a second incoming call while you’re already on a call

Yes. You can use a compatible third-party wireless charger (not provided) to charge the case. For best results, center the button (located on the back of the case) on the wireless charging pad. The charging case LED will glow solid amber to indicate the case is centered correctly and has begun charging.

A proper fit is critical to ensure the best audio performance and noise cancellation; an eartip with a loose or leaky seal can result in lower performance. The guide in the Bose app helps illustrate how to change out eartips and stability bands to try different sizes. After a comfortable fit is achieved, try the Earbud Seal Test located in the settings menu to ensure you are getting the best noise cancellation and listening experience. With a good seal, CustomTune technology ensures listeners are getting the best noise cancellation and audio performance.

If you find that none of the provided eartips and stability bands meet your needs, you may need alternate sizes. Extra Small and Extra Large eartips and sizes 0 and 4 stability bands are available online or through Bose Customer Service.

Yes, you can use either the left or right earbud independently for listening to audio or for phone calls. Controls on your bud will remain as when you are using both buds, and any shortcuts you have set will remain as you have set them. For optimal noise cancelling performance, both buds should be used together.

What’s in the Box
  • 2 Bose Ultra Open Earbuds
  • Charging case
  • USB-C® (A to C) cable (12")
  • Safety sheet

The Bose Ultra Open Earbuds are a totally new kind of audio wearable device: premium sound built into a cuff-shaped earbud that doesn’t cover your ear. Proprietary Bose OpenAudio technology allows the earbuds to play rich, immersive audio privately even though the speakers on the earbuds sit a short distance from your ear canal, leaving you open to the sounds of your surroundings. The cuffs hook around the outside of your ear so gently that you might forget they’re even there, so you can leave them on all day, always ready for music, calls, or videos.

The Open Earbuds were designed from the ground up to give you a soundtrack for your life: to let you enjoy your music without blocking your ears, in a shape so comfortable you can almost forget you’re wearing any earbuds at all. The engineering of these earbuds was a matter of squeezing Bose OpenAudio technology — which projects deep, rich sound across a short distance of open space to your ear canal — into a shape that could grip your ear extremely gently, leave your ear open to outside sounds, and contain a long-lasting battery. This design process resulted in the Open Earbuds’ unique shape, inspired by ear cuff jewelry. The light-as-air flex arm connects the audio portion of the earbud to a battery barrel that goes behind your ear, providing just enough grip to keep the earbuds secure on any size ear.

Yes. The Open Earbuds are excellent for exercise, thanks to their confident stability on your ear, powerful sound, and open design. Bose’s unique OpenAudio technology allows air to keep your ears cool and dry while you enjoy both your music and sounds from your environment, such as city sounds, nature, input from a coach or workout partner, or sounds that help you play a sport such as tennis or basketball.

Yes. The combination of skin-safe materials, a fully open design, long battery life, and unparalleled comfort means you can leave the earbuds on all day, always connected to your device and ready to produce rich audio the moment you need it.

In stereo mode, the earbud batteries will provide up to 7 hours of play time or 48 hours of standby time (no audio playing). For all-day wear that involves a mix of audio listening and standby, the battery life will vary depending on the proportion of each. For example, 5 hours of audio would leave 10 hours of standby life remaining. And if the battery does run out, a quick 10-minute charge in the case will add up to 2 hours of play time.

Yes. You can slide the earbud slightly up or down the outside of your ear to adjust for comfort, preferred sound balance, looks, or to avoid interference with jewelry. 

Yes. The Open Earbuds are uniquely designed to attach to a part of the ear that does not interfere with most glasses, hats, and piercings. If your accessories touch the product, that’s no problem as long as the earbuds remain comfortable and secure. The magnets that help the earbuds attach to their charging case may occasionally stick slightly to jewelry made of ferromagnetic metals like nickel; this is not damaging to the earbuds or the jewelry, but if bothersome can be avoided by slightly sliding the earbud up or down the ear, away from the jewelry.

OpenAudio is a proprietary Bose technology that allows audio played a short distance from your ear canal to be rich, deep, and private — without sealing your ear. Each earbud uses a tiny dipole transducer system engineered for loud-and-clear personal audio that stays at the ear — instead of going everywhere else.

It’s easy to hear the difference Bose OpenAudio makes by comparing the power of the Bose Ultra Open Earbuds with a traditional set of earbuds held slightly outside your ear. If you remove the traditional earbud from your ear canal and hold it near your ear at the same distance that the Open Earbuds sit, you’ll notice the much greater volume and richer bass from the Open Earbuds.

Bose OpenAudio directs rich, deep audio into the ear canal while using proprietary technology to minimize sound spillage in other directions. In most environments and at most listening levels, people around you won’t hear a thing. If you turn up the volume all the way in a very quiet environment, others may hear that something is playing from your earbuds, but they won’t be able to hear any detail unless they get very close.

No. By design, the Open Earbuds don’t block out the world or have noise cancelling, so you can enjoy your music while staying open to the sounds of the world around you. They do have an automatic volume control feature, available in the Bose app, that helps you hear your music evenly as your environment changes from quiet to loud and back.

Yes. The Ultra Open Earbuds have the Bluetooth multipoint feature allowing them to connect to two source devices at the same time. This is a recent update as of July 2024, so be sure to set up your earbuds with the Bose app to receive software updates.

The Bose app also allows you to customize the shortcut function on each earbud’s button, and one of the available options is Switch Source. Setting a shortcut to Switch Source will enable you to switch between previously connected Bluetooth source devices with a press and hold of the earbud button without needing to take the earbuds off.
