Bose QuietComfort Headphones are the successors to QuietComfort 45 Headphones. They deliver high-fidelity audio performance and world-class noise cancellation that allow you to hear more of your music and movies—while travelling, at the office, or at home.
QuietComfort Ultra Headphones offer our most premium design and our most advanced technologies, for the best Bose listening experience in a headphone. With QuietComfort Ultra Headphones, you will enjoy our best headphone noise cancellation, audio quality personalized with CustomTune, and voice pickup, among other premium features.
Proprietary TriPort acoustic headphone structure utilizes external ports to vent the earcups and effectively enlarge the acoustic volume, without increasing the size of the earcup. The result is better audio and active noise reduction from a smaller, lighter, more comfortable headphone.
Bose QuietComfort Headphones utilize both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach for active noise reduction, placing microphones both inside and outside the earcups. 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. Meanwhile, passive noise reduction is achieved by the combination of earcup fit, design, and clamping force of the headband.
Aware Mode turns on the external microphones of QuietComfort Headphones and feeds ambient sounds into the headphones, enabling awareness of the sounds in the environment, such as cars and emergency vehicles, while still enjoying audio content.
These headphones were designed to maximize all the features that contribute to comfort, especially when you’re using the headphones for extended periods of time. All materials have been selected for their comfort and lightweight properties. Protein leather is used for its comfort, durability, and acoustical properties. The earcups rotate easily for a uniform, comfortable seal. And most importantly, stability is achieved with minimal clamping force, allowing for hours of comfortable wear.
Yes. Bose QuietComfort Headphones have an adaptive microphone system that allows you to use the headphones during calls when connected to any smartphone. In addition to traditional calls, the headphones will work with many apps that use Voice over Internet Protocol (VoIP), such as Zoom or FaceTime. The microphone system adapts to your environment to isolate your voice from competing background noises and wind so that you can confidently take a call or speak to your voice assistant anywhere you go—knowing you will be heard clearly and naturally.
First, make sure your headphones are turned on with the slider switch in the middle “On” position. Next, slide and hold the switch to the Bluetooth icon until the Bluetooth LED flashes blue or when the voice prompt indicates the headphones have entered into pairing mode. Please note, if this is your first time connecting the headphones, they will automatically turn on into pairing mode. Voice prompts will provide you with additional guidance. We recommend using the Bose app to complete the pairing process, however, Bluetooth settings on your device can be used to complete pairing.
Yes. Multipoint technology allows Bose QuietComfort Headphones to maintain a connection to two devices at the same time—for example, an iPad and a smartphone. So while you’re watching video on the connected iPad, the headphones will automatically pause the video to answer a call from the connected smartphone. When the call is finished, the headphones switch back to the video on the iPad.
Bose QuietComfort Headphones have a range of up to 30 ft. (9 metres) from the source device. This range may be reduced by physical obstructions, such as walls and doors, or by interference from other electronic devices. Pops or a cracking noise may be heard if there’s interference with the Bluetooth connection. If that happens, move away from wireless routers or microwaves and bring your headphones closer to the Bluetooth device.
The headphones can be charged using the USB-C cable supplied in the box and plugging into a USB port on a PC, laptop, or wall charger. Allow up to 2 hours for the headphones to fully charge. The battery light indicator will show an amber light while the headphones are charging and turns green when fully charged. When you don’t have time for a full charge, the fast-charge feature provides up to 4 hours of play time from a quick, 15-minute charge.
Bose QuietComfort Headphones use a lithium-ion rechargeable battery that provides up to 24 hours¹ of audio playback with noise cancelling turned on.
Yes. You can continue to listen to your source even if the battery power is depleted. Without power, the headphones operate in a passive mode and neither active noise cancellation nor Active EQ is able to function.
Bose QuietComfort Headphones also give you two options when it comes to audio EQ. Do nothing and the bass, midrange, and treble of whatever you’re listening to will be adjusted automatically to make it sound great. Or choose Equalizer in the settings of the Bose app to change the audio levels yourself to however you like them best. Either way, you’ll enjoy immersive sound at any volume.
The larger middle button on the right earcup is the Multi-function button. It initiates play/pause and other track controls for videos and music, answers and ends calls, and also provides access to your phone’s default virtual assistant, like Siri. The buttons on either side of the multi-function button are volume +/– buttons. They allow you to easily adjust volume in an intuitive up/down vertical orientation.
On the left earcup there is a single Action button. This toggles between Quiet Mode (noise cancelling), Aware Mode, and your Custom Modes. This is also a shortcut button; when you press and hold the button for approximately 2 seconds, your shortcut, such as battery life status or Spotify Tap, will activate.
Using the Multi-function button on the back of the right earcup, QuietComfort Headphones give you access to your phone’s default virtual assistant, like Siri.
No. In general, the audio/video delay will be excessive and most noticeable in games where action and audio are supposed to be synchronized.
Spotify Tap allows Spotify users to access their music with a single tap on a designated control on their headphones. Press and hold the “Action” button on the left earcup to start your listening session, and press down again for Spotify to offer up recommendations for other music you might like. You need a Spotify account, and can configure the shortcut control to activate Spotify Tap using the Bose app.

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 App. The Shortcut on one or both earbuds can also be customized in the Bose 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

• 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 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.
Yes. The Ultra 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.
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”).
