Bose's flagship noise-canceling headphones

The Bose QuietComfort Ultra headphones offer the company's best noise cancellation ever. If you know their history, that's saying a lot. These premium over-ear headphones are also made from high-grade, lightweight materials and feature Bose Immersive Audio — the company's 3D spatial audio technology.

Bose's flagship noise-canceling headphones

The Bose QuietComfort Ultra headphones offer the company's best noise cancellation ever. If you know their history, that's saying a lot. These premium over-ear headphones are also made from high-grade, lightweight materials and feature Bose Immersive Audio — the company's 3D spatial audio technology.

Bose QC headphones folded up

Unlike many of the newer high-end noise-canceling headphones, the Bose QC Ultra sports a fold-up design for travel.

You can listen in traditional stereo mode or expand the soundstage with two optional "immersive" modes, including one that uses the QC Ultra's built-in head-tracking capabilities. Sound comes at you from all sides, behind you, and even above your head. Those spatialized effects are created by Bose's special processing, which works with any type of music (or music service).

Manually adjust your noise cancellation, awareness, and sound

Bose says they've re-engineered their noise-canceling circuitry with an updated chipset, better processing, and an advanced array of microphones. The company's CustomTune technology — also found in their excellent QC Ultra earbuds — calibrates the noise cancellation and sound to you and your surroundings. It account for external noises and even the physical properties of your ears, then adjusts itself in real time.

You also have control over how much sound you let in and out. "Quiet" mode delivers the maximum level of noise cancellation, while "Aware" mode lets in external sounds, or you can choose a blend of both. Use the Bose Music app, a free download for Apple® and Android™, to choose from 11 discrete levels of noise-cancellation and awareness, along with your immersive audio preference.

Strong, reliable wireless connection to multiple devices

Music plays wirelessly via Bluetooth 5.3, one of the newest versions of Bluetooth that offers a strong, reliable connection. Multipoint connectivity means you can pair your laptop and phone at the same time. A game changer for work — you can quickly hop from music to podcasts to calls to meetings.

And here's another touch: Bose's SimpleSync™ feature lets you pair the headphones directly to compatible Bose Smart Soundbars. Connecting the headphones lets you watch TV late night without disturbing others.

Easy on-ear controls and clear calls

There's a combination of buttons and touch panels that let you control music, calls, volume, and noise cancellation. The multi-function button on the right ear cup can be customized in the app. The powerful microphone array that makes the noise cancellation so effective helps make for clear calls, too. Bose's processing can home in on your voice and eliminate background noise.

Lightweight, relaxed fit

Bose QuietComfort models have a great track record when it comes to comfort. The previous-generation QC 45s were named one of our top 5 most comfortable headphones. They earned high marks on our in-house tests for feeling "ultra-light."

The QC Ultra headphones sport the similar iconic design, but Bose says the premium materials make them even sturdier without adding significant weight. I can wear Bose QC headphones for entire work shifts without fatigue or strain on my head or ears. And of course, work and travel are even more bearable when you have world-class noise-canceling circuitry hushing loud distractions.

24 hours of wireless use with noise cancellation

The QuietComfort headphones have a built-in rechargeable battery and include a charging cable. On a full charge, you can get up to 24 hours of standard wireless listening with noise cancellation on or 18 hours of immersive audio. A voice prompt tells you how much battery life you have left every time you power them on.

Product Research


Overview: The QuietComfort Ultra headphones feature world-class noise cancellation, superior build quality, and a new Immersive Audio feature. These lightweight headphones are made with premium materials for maximum comfort and durability. QuietComfort Ultra comes with an audio cable, a USB-C charging cable, and a zippered storage case.

Active Noise Cancelling: The QuietComfort Ultra achieves its iconic noise-cancelling through a combination of passive and active noise cancelling. The combination of the over-ear headphone design and clamping force of the headband produces a natural reduction of external noise inside the earcups. Microphones located inside and outside of each ear cup continually measure, compare, and react to outside noise. The proprietary noise cancellation circuitry then sends an out-of-phase signal to effectively cancel out the noise. The circuitry also goes the extra mile to eliminate the soft hiss that occurs with most electronics. Pressing the Multi-function button on the right earcup switches between the following modes: Quiet Mode for full noise cancelling, Aware Mode to let in some of your surroundings while you still enjoy your audio content, or Immersion to put the music out in front of you. In the Bose Music app, you can create up to seven of your own custom modes, such as Wind Block, based on your listening preferences and environment.

Immersive Audio: Bose Immersive Audio is a new spatialized audio mode that provides more realism by moving the sound out of your head and placing it in front of you. You can use Immersive Audio with any streaming content, giving it a richer sound quality and improved clarity. Immersive Audio makes the audio sound like it's coming from two stereo speakers placed in front of you. With the Motion setting, the speakers follow the movement of your head, keeping the soundstage in front of you. This is the default setting in Immersion Mode. The Still setting must be selected in the Bose Music app. It keeps the "speakers" stationary when you move your head for a more realistic listening experience. A few seconds after you stop moving your head, the soundstage recenter your position. Using Immersive Audio requires more battery power, thus reducing the estimated battery life when in use. When you take a phone call, Immersive Audio is temporarily turned off, and returns to the previous setting after the call.

ActiveSense: While in Aware Mode, you can take advantage of Bose's ActiveSense technology. Aware Mode with ActiveSense lets you hear your surroundings while reducing unwanted noise. When sudden or loud noises occur near you, the noise cancellation increases to automatically suppress it. Once the noise stops, noise cancellation automatically returns to its previous setting. ActiveSense can only be enabled in the Bose Music app.

Bluetooth 5.3: The QuietComfort Ultra features Bluetooth 5.3 wireless technology that lets you listen to your favorite music and make phone calls free from wires. Multi-point technology lets you connect to two mobile devices simultaneously. This allows you to watch a movie on your tablet while maintaining a connection to your phone. Bose software lets you seamlessly transition between the two devices when a call comes in. You can store up to eight devices in the headphone device list so you can quickly pair with any of them. If you have an Android device, you can connect using FastPair. QuietComfort Ultra also accesses the native Voice Assistant on your device (Siri, Google, Bixby).

Audio Cable: The headphones include a 42" audio cable so you can listen to your audio even if a Bluetooth connection isn't available, or the battery is depleted. When the cable is plugged into the headphones, the Bluetooth connection and the microphone on the earcups are disabled.

SimpleSync: Bose's SimpleSync technology lets you connect the headphones to a Bose Smart Soundbar or Bose Smart Speaker to listen in private. SimpleSync uses Bluetooth to connect, giving you a range of up to 30 feet. You can control the headphone volume independently of the Smart Soundbar or Speaker. Compatible products include Smart Soundbar (models 900, 700, 600), Smart Speaker 500, Home Speaker 500 and 300, and Bose Portable Smart Speaker or Portable Home Speaker. You can also connect the headphones and speakers using the Bose Music app.

Bose Music App: The Bose Music app makes it easy to connect to your Bluetooth devices, and switch between them whenever you desire. It improves your wireless experience by helping you pair your headphones to multiple devices by a simple swipe. The app lets you adjust the Immersive Audio settings from Motion to Still, and set a shortcut so you can cycle through the settings on the headphones. You can also get software updates, choose your Voice Prompts language, view the battery status, get product tips, and adjust personalized settings from the app. The adjustable EQ lets you adjust the bass, midrange, and treble to shape the music the way you like it. The free Bose Music app is available for download from the App store for Apple devices running iOS 15.0 or later, and from Google Play for Android devices (version varies with device).

On-board Controls: The QC Ultra wireless headphones feature a volume strip and a Multi-function button on the bottom of the right ear cup. Sliding your finger up or down the strip raises or lowers the volume. The Multi-function button controls music playback, including play/pause (single-press), skip forward (double-press), and skip backward (triple-press). The button also lets you answer (single-press), end or reject a call (double-press). When on a call and a second call comes in, you can put the first call on hold and answer the second (single -press) or reject the second call (double-press). Activating your mobile device's voice assistant requires setting a shortcut in the Bose Music app.

Voice Prompts: Voice Prompts in the headphones guide you through the Bluetooth pairing process, powering on and off, and for battery status updates. You can choose the language for the voice prompts in the Bose Music app.

On-head Detection: Sensors on the headphones identify when they are being worn and when they are taken off. If you are listening to audio with the headphones and you lift the right earcup or take the headphones off, the music will automatically pause. Replacing the right earcup or putting on the headphones resumes the audio playback. If a call comes in while the headphones are off, putting them on will automatically answer the call.

Battery Powered: The headphones have a built-in Lithium-ion rechargeable battery, which powers Bluetooth, Quiet Mode, Immersion Mode, and Aware Mode. Each time you power on the headphones, you'll receive a voice prompt with the remaining battery charge expressed as a percentage. When the battery in near depletion, you'll get a "Battery Low" prompt. The battery charges in about 3 hours via the supplied USB cable using a 5V / 0.5A USB charging port (or one with a higher amperage). A fully charged battery will power the headphones for up to 24 hours when connected wirelessly (Bluetooth and ANC). In Immersive Audio mode, the battery life is 18 hours. A 15-minute Quick Charge can power the headphones for up to 2.5 hours (2 hours with Immersive Audio). When the battery is depleted, you can still listen to music by plugging in the supplied audio cable.

High Quality Materials: The Bose QC Ultra wireless headphones are crafted with premium materials for lightweight comfort and durability. The plush ear cups are molded with glass-filled nylon instead of plastic for a lightweight feel and for strength. The stainless steel headband springs and pivots are built to last for years. The ear cushions are made of synthetic protein leather with a silicone bead to passively block external noise.

Folding Ear Cups: The QC Ultra headphones feature hinged ear cups that fold and rotate for compact storage in the supplied carrying case.
