QuietComfort Ultra Earbuds offer all the same features as their predecessor, QuietComfort Earbuds II, plus breakthrough Bose Immersive Audio and the addition of Immersive Audio settings for Custom Modes. Other new features include Snapdragon Sound certification, using hi-res audio and low latency codec, Qualcomm aptX Adaptive, and Google Fast Pair. QuietComfort Ultra Earbuds also feature a new metallic finish on earbuds, as well as a new notch/key alignment feature for stability bands that makes them easier to swap in and out.

Immersive Audio allows you to hear audio as if it were coming from beyond your QuietComfort Ultra Earbuds, 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 QuietComfort Ultra Earbuds 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 controls on the left and right earbud surfaces are the same, and they include:

• 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 Shortcut. The default Shortcut function on both buds is to toggle back and forth between Quiet Mode (full noise cancelling) and Aware Mode (hear outside sound). You can add additional noise cancelling modes at sound levels between Quiet and Aware using the Bose Music app. The Shortcut on one or both earbuds can also be customized in the Bose Music app to access a mobile device’s built-in voice assistant

• Tap once to accept an incoming call

• Tap twice in quick succession to end a call, or decline an incoming call

Yes. The Single-bud Use feature allows you to take calls and listen to music using one bud. It will also seamlessly switch between your earbuds, and switches automatically if one of the earbuds runs out of battery or disconnects from Bluetooth®.

Yes. The Bose QuietComfort Ultra Earbuds have passed IPX4 testing, which means they are protected against sweat and splashing water from any angle. The interior of the charging case is resistant to water or sweat that may remain on the buds when they are placed inside for charging; however, it is not recommended that the outside of the case be exposed to water.

You should take some time to experiment with different eartip and stability band sizes to arrive at a combination that suits you, providing a gentle seal and a comfortable, stable experience. Keep in mind that it’s common for left and right ears to vary slightly in shape, so sizes may not match from left to right. Also, eartip and stability band sizes may be mixed and matched (such as using a size small eartip with a #3 stability band). If you find that you need alternate sizes, extra small and extra-large eartips and stability bands are available through Bose Support.

There are two lights: an Earbud status light inside the case between the earbuds, and a Charging Case status light on the outside of the case. Earbud status light (inner):

• Slowly blinks blue – Ready to connect

• Solid blue (5 seconds) – Connected

• Blinks white 2 times – Device list cleared

• Solid white (5 seconds) – Earbuds are fully charged

• Solid amber (5 seconds) – Earbuds are charging

• Blinks white 2 times – Reboot complete

• Blinks white 3 times, repeated – Updating earbud software

• Blinks amber and white – Error, contact Bose customer service

Charging Case status light (outer):

• Solid white – Case is fully charged (100%) and plugged in

• Solid white (5 seconds) – Case is charged (34% to 99%)

• Solid amber (5 seconds) – Case has low charge, less than one full earbud charge remaining (10% to 33%)

• Blinks amber 2 times – Case needs to charge (Less than 10%)

• Solid amber – Case is charging

• Blinks white 3 times, repeated – Updating case software

• Blinks amber and white – Error, contact Bose customer service

Yes. Bose QuietComfort Ultra Earbuds have an adaptive microphone system that allows you to use them during calls when connected to any smartphone. In addition to traditional calls, the earbuds work with many apps that use Voice over Internet Protocol (VoIP), such as Teams, Zoom, or FaceTime. The microphone system adapts to your environment to isolate your voice from competing background noises and wind. In addition, self-voice (adjustable in the Bose Music app settings) allows you to hear yourself naturally, as if you weren’t wearing earbuds at all, so you can monitor the volume of your voice and minimize the effects of speaking while wearing earbuds.

Snapdragon Sound refers to an audio and software processing infrastructure developed by Qualcomm, focusing on robust and low latency Bluetooth connectivity and leveraging the aptX Adaptive codec. AptX Adaptive will “adapt” the audio quality seamlessly and continuously based on the strength back to the source’s device to maintain a good wireless connection and avoid audio dropouts. This means that for a great wireless connection, you can get the highest possible audio quality up to and including “lossless” audio. The normal sampling rate applicable in your Bose QuietComfort Ultra Earbuds is 44.1 kHz and will adapt up to 48.1 kHz when “high resolution” listening. The codec also has a low latency mode, aka “Gaming Mode.” Just as with audio quality, the codec will “adapt” to achieve the best (lowest) latency possible given the current wireless conditions.

Snapdragon Sound is applicable only to Android users with Snapdragon Sound Certified devices.

Google Fast Pair is a technology developed by Google to expedite the initial pairing process between source devices and headphones. Android users (OS 6.0 or newer) will enjoy the rapid setup Google Fast Pair has to offer by simply turning on their headphones and selecting the Google pair pop-up window on their Android device (Android device location services and Bluetooth must be set to “on”).

Why buy from Bose.com

¹Testing conducted by Bose in June 2023 using production-representative Bose QuietComfort Ultra Earbuds and a variety of music tracks using A2DP Bluetooth audio streaming at RSSI signal strength of 75 dB. Volume set to playback loudness of 75dB, 3-band EQ set, to zero in Quiet Mode (full noise cancellation). With Immersive Audio off, playback time was up to 6 hours before battery depletion. With Immersive Audio on, playback time was up to 4 hours before battery depletion. Battery life varies based on settings and usage.


²Testing conducted by Bose in July 2023 by inserting production-representative Bose QuietComfort Ultra Earbuds with battery depleted (to the point of no audio playback) into a fully charged Bose QuietComfort Ultra Earbuds charging case and charging earbuds to 100%, then resuming audio playback until battery depletion. Testing resulted in three (3) complete charging cycles by the case before a full charge was no longer possible.

³Testing conducted by Bose in July 2023 using production-representative Bose QuietComfort Ultra Earbuds and Bose QuietComfort Ultra Earbuds charging case. Quick charge testing consisted of inserting earbuds with battery depleted (to the point of no audio playback) into a fully charged case and charging earbuds for 20 minutes, then resuming Bluetooth A2DP audio playback with volume set to loudness of 75 dB, 3-band EQ set to zero, in Quiet Mode (full noise cancellation) with Immersive Audio switched off, resulting in up to 2 hours of playback time before battery depletion.


Time to achieve fully charged earbuds was determined by inserting earbuds with battery depleted (to the point of no audio playback) into a fully charged case and charging earbuds to 100% battery charge.

Rated 5 out of 5 by from Very enjoyable, indeed. I have owned previous models of earbuds. I did want to pick the blue, but with my work and personal lives, the black was again my pick. The features that allow me to have more control of my earbuds is an excellent thing to have. I do like the levels of noise canceling because, indeed, I do at times need to hear the outside world. The profile of these earbuds are closer to the ear and don't exactly 'stick out'. These are things I need in my life. I'm thankful for finding Bose earbuds because before that I was just struggling with getting the things I wanted to hear in my ear, clearly. Thank you.

Rated 5 out of 5 by from Superb earbuds, glad I made the upgrade I am a huge Bose fan - I just prefer their sound to all others. I've owned the Bose Soundsport Free earbuds for years now. I love the sound, and they stay in my ears. However, and this is me, I always felt they would fall out (they really don't!). I asked for the Bose QC Ultra earbuds though for a gift because I was very intrigued by the immersion sound. I absolutely love them! The sound is incredible, especially on immersion. The noise canceling (which I didn't really need) works fantastic- as well as the ANC on my Bose QC45 headphones. I never expected that! The fit is very comfortable. The buttons are responsive and easy to use. My favorite feature may be though that they pause the sound if you pull one earbud out. I have a habit of pulling one out when someone tries to talk to me because the button on the Soundsport was always finicky for me, but then I still had noise in one ear. It's really a game changer for me. I think I've made everyone in my house listen on the QC Ultra, the sound is that good. I find I wear them far more often than before, which used to be just one daily walks. Now, I have them on in the house, for meditations, etc.

Rated 5 out of 5 by from Surprisingly worth the price! I have the Bose QC 45. I loved them on air travel but they took a lot of extra space in my bag. I upgraded to the Bose QC Ultra. I love them! The sound is amazing. The noise cancelling is great. I even put them on in the plane and the read instead of listening. It removes a lot of the engine noise. Then when tired of reading I hit play and get lost in my music.

Rated 5 out of 5 by from The Great Features Of The Bose QuietComfort Ultra I bought a pair of Bose QuietComfort Ultra Earbuds as an upgrade to the QuietComfoet Earbuds I bought in 2022. Once I put them in, I was very happily surprised at the performance, stability and features these neq earbuds had compared to the 2022 model. Instead of the stability wings, they replaced them with stability bands. I was happy to experience the new fit of these bands when I inserted them in my ears. The stability bands held firm and snug in my ear much different than the wings of the older model, and I hope Bose continues with this design for more earbuds to come. The sound that was produced was very rich yet crisp and not grainy, hissy nor poppy. They still have the same noise cancellation features and presets, but now there's a new sound mode called Immersion Audio that offers spatial audio effects while still or in motion, and the effect sounds awesome! I highly recommend these earbuds if you're looking for a quality sound experience while relaxing at home or on the go at work or at the gym.
