The Bose QuietComfort Ultra Headphones Wireless are top-of-the-line noise cancelling (ANC) headphones. While they look similar to the Bose QuietComfort 45/QC45 Wireless, they have CustomTune technology; the headphones can adjust their sound profile and noise cancelling based on your unique hearing capabilities and environment. Like the Bose QuietComfort Ultra Earbuds Truly Wireless, they also have Immersive Audio, which offers head tracking to give you a more exciting audio experience. They even support aptX Adaptive, a codec that dynamically adjusts its performance based on your usage, whether you're streaming high-quality audio or watching video.

Our Verdict

8.1 Neutral Sound

The Bose QuietComfort Ultra Headphones are great for neutral sound. These headphones have CustomTune technology, allowing them to adjust their sound based on your unique hearing characteristics. Their sound profile supplies extra thump and rumble. Meanwhile, the extra bass doesn't overwhelm vocals and instruments, which are still pretty clear and present in mixes. Their companion app offers a graphic EQ and presets if you prefer a different sound. They also support a head-tracking feature, creating a more immersive audio experience.

Pros
  • Very comfortable and well-built.
  • Graphic EQ and presets available via companion app.
Cons
  • Poor passive soundstage performance.
8.3 Commute/Travel

The Bose QuietComfort Ultra Headphones are impressive for commuting and traveling. They have a well-built design that's comfortable for long days on the go. They're also equipped with a superb ANC system, so they can block out the low rumble of bus and plane engines and last almost up to 30 hours with their ANC on. Their carrying case helps protect the headphones from damage, too.

Pros
  • Outstanding noise isolation performance.
  • Very comfortable and well-built.
Cons
  • Poor passive soundstage performance.
7.5 Sports/Fitness

The Bose QuietComfort Ultra Headphones are good for sports and fitness, although over-ears may not be the best choice overall for this purpose. They're lightweight and feature noise cancelling to block out people at the gym and a transparency mode to stay aware outdoors. While they're very comfortable, they're also bulky and can fall off your head with moderate movement. They also lack an IP rating for water resistance, but that's very common for over-ears.

Pros
  • Outstanding noise isolation performance.
  • Very comfortable and well-built.
Cons
  • Can fall off of your head with moderate head movement.
8.2 Office

The Bose QuietComfort Ultra Headphones are great for office use. They have a comfortable fit and last well throughout your work day, so you don't have to worry about recharging them every day. They also support multi-device pairing, so you can stay connected to your PC and smartphone simultaneously. Thanks to their ANC system, you can easily block out chatty coworkers and the hum of computer fans.

Pros
  • Outstanding noise isolation performance.
  • Very comfortable and well-built.
  • Supports multi-device pairing.
Cons
  • Poor passive soundstage performance.
6.3 Wireless Gaming

The Bose QC Ultra Headphones are Bluetooth-only headphones. Unfortunately, they have high latency using the SBC codec, so your audio and visuals won't be in sync. Luckily, they support aptX Adaptive, which is a codec that adjusts its performance based on your content. If you're gaming, it can ensure a lower latency experience. However, there's still some delay present.

7.3 Wired Gaming

The Bose QuietComfort Ultra Headphones are decent for wired gaming, though there are a couple of caveats. First, they only support audio via analog, and second, the headphones still need to be powered on to use the analog connection, so you'll still need to keep an eye on battery life while using them. These headphones have an extra dose of bass that can help emphasize sound effects in your gameplay, while speech and soundtracks sound clear. They also have a comfortable fit that's suitable for long gaming sessions.

Pros
  • Outstanding noise isolation performance.
  • Very comfortable and well-built.
Cons
  • Poor passive soundstage performance.
  • Needs to be powered on even when plugged in.

7.7 Phone Calls

The Bose QuietComfort Ultra Headphones are good for phone calls. They have an integrated mic with good recording quality, so your voice is clear and easy to understand. That said, the mic has trouble separating speech from background noise, so it can be hard to hear you clearly if you're making a call from a busy office. On the upside, they have outstanding noise isolation performance thanks to their adaptive noise cancelling system.

Pros
  • Outstanding noise isolation performance.
  • Mic has very good recording quality.
Cons
  • Poor passive soundstage performance.
  • 8.1 Neutral Sound

Differences Between Sizes And Variants

The Bose QuietComfort Ultra Headphones come in three color variants: 'Black,' 'White Smoke,' and 'Sandstone.' We tested the 'Black' model, and you can see our model's label here. If you encounter another variant of these headphones, please let us know in the forums, and we'll update our review.

Compared To Other Headphones

The Bose QuietComfort Ultra Headphones are premium over-ears and are a step up from the Bose QuietComfort 45/QC45 Wireless. There are new features like CustomTune technology, so the headphones can adjust their sound and noise cancelling adaptively based on your hearing characteristics and environment. Like the Bose QuietComfort Ultra Earbuds Truly Wireless, they also support Immersive Audio, a head tracking feature similar to Apple's Spatial Audio. As with most Bose products, you can expect a high level of noise isolation, outperforming similarly premium picks like the Sony WH-1000XM5 Wireless and Apple AirPods Max Wireless.

Check out our recommendations for the best noise cancelling headphones, the best wireless Bluetooth headphones, and the best Bose headphones.

Sony WH-1000XM5 Wireless

The Bose QuietComfort Ultra Headphone Wireless have the edge over the Sony WH-1000XM5 Wireless. The Bose are significantly more comfortable and better built. They have a slight edge in noise isolation, too, but the difference is fairly minor; both choices are still well-suited for noisy environments. The Bose headphones also support a suite of aptX codecs for high-quality audio. Meanwhile, the Sony support LDAC codec, which is nice if you want to stream high-quality audio, and you can use them passively via analog. If you want to use the Bose wired, you'll have to turn them on.

Apple AirPods Max Wireless

The Bose QuietComfort Ultra Headphones Wireless have the edge over the Apple AirPods Max Wireless. While both headphones have a premium feel, the Bose are significantly more comfortable, and their ANC can block out more background noise. Their battery life is a bit longer, and they support multi-device pairing, so you can stay connected to two devices at a time. Their companion app offers sound customization features to help you tweak their sound. They even support aptX Adaptive, a codec that dynamically adapts to your content, giving you better sound quality or lower latency. The Bose and Apple both have spatial audio features to help your audio sound more immersive, and only the Apple headphones have an H1 chip for seamless pairing with iOS devices.

Sennheiser MOMENTUM 4 Wireless

The Bose QuietComfort Ultra Headphones Wireless are better than the Sennheiser MOMENTUM 4 Wireless for most purposes. The Bose are higher-end headphones with a much more comfortable fit and a better noise isolation performance. However, the Sennheiser headphones last about twice as long off a single charge, so you might prefer them for long trips or if you don't want to recharge your headphones often.

Sonos Ace Wireless

The Bose QuietComfort Ultra Headphones Wireless and the Sonos Ace Wireless are both premium models, and deciding between them comes down to the details. They're equally comfortable and well-built, with outstanding ANC systems. However, the Bose headphones have a better overall microphone performance, and their app offers slightly more customizability in performance. You can adjust their sound using the graphic EQ or presets. Their virtual soundstage feature is also a bit more than on/off, as you can select if you want the virtual speakers to stay in front of you or if you want them to move with your head movements. If you're already a Sonos user, you'll get the most out of the Sonos headphones, especially if you have a compatible soundbar. You can use the TV Swap Audio to receive audio from your soundbar, though there's some audio delay present. However, there have been user reports of issues regarding the app's lack of functionality.

Bose QuietComfort 45/QC45 Wireless

The Bose QuietComfort Ultra Headphones Wireless have the edge over the Bose QuietComfort 45/QC45 Wireless. While both models look similar, there are a couple of changes. The Ultra are better built and have a different control scheme with a volume slider. They also have CustomTune technology, which automatically adjusts their sound, and noise cancelling performances based on your unique hearing characteristics and environment. They support Immersive Audio, too, which is an adjustable head-tracking feature that can create a more immersive sound. The QuietComfort Ultra Headphones have a greater codec selection, including aptX Adaptive. That said, the Ultra need to be powered on to be used via analog, while the QC45 support passive playback.

Sony WH-1000XM4 Wireless

The Bose QuietComfort Ultra Headphones Wireless and the Sony WH-1000XM4 Wireless are both high-end headphones, and depending on your needs, you may prefer either pair. Both headphones have fantastic ANC systems, so you'll get top-tier noise isolation from either pair. The Bose are more comfortable and have a slightly more neutral sound, which some users may prefer, and their mic offers a better overall performance. They also support aptX Adaptive, which is a codec that automatically adjusts its performance based on your audio content, so you'll be able to listen to audio in higher quality or, if you're streaming video, reduce lip sync mismatch. The Sony headphones support passive playback and LDAC codec, allowing you to stream higher-quality audio than with the default SBC codec.

Dyson OnTrac Wireless

The Bose QuietComfort Ultra Headphones Wireless are better noise cancelling headphones than the Dyson OnTrac Wireless. The Bose headphones offer better isolation performance and weigh less. Plus, their app offers a few extras like surround sound and a bit more control over the EQ compared to the Dyson. That said, the Dyson have a longer battery life and a flashier metal frame with softer ear pads.

Anker Soundcore Space Q45 Wireless

The Bose QuietComfort Ultra Headphones Wireless are better over-ears than the Anker Soundcore Space Q45 Wireless. The Bose are premium headphones with a more comfortable, well-built design and better overall noise isolation performance. They can access an Immersive Audio feature, which allows audio to follow your head movements, and they support aptX Adaptive, a codec that automatically adjusts to your content, ensuring either low latency or high audio quality. That said, the Anker are still worth considering if you're looking for significantly cheaper over-ears with excellent noise cancelling.

Sony WH-CH720N Wireless

The Bose QuietComfort Ultra Headphones Wireless are better than the Sony WH-CH720N Wireless due to significantly better noise cancellation. They also have better build quality and a greater Bluetooth codec selection. On the flip side, the Sony headphones are lighter and have a longer battery life, and the app supplies two extra EQ sliders.

Bose QuietComfort 35 II/QC35 II Wireless 2018

The Bose QuietComfort Ultra Headphones Wireless are a later generation of the Bose QuietComfort 35 II/QC35 II Wireless 2018. While they look similar, the Ultra are better built and have CustomTune technology, so the headphones automatically adjust their sound and noise isolation performances based on your unique hearing capabilities and the environment around you. They also have a head tracking feature, whereby audio follows your head movements for a more immersive experience and a longer continuous battery life. However, the QC35 II have a more neutral sound, which some users may prefer, and they support passive playback. You have to turn on the Ultra to playback audio via analog.

Beats Studio Pro Wireless

The Bose QuietComfort Ultra Headphones Wireless are better than the Beats Studio Pro Wireless. The Bose have a more comfortable fit and a better build quality. Their ANC feature blocks out more noise across the entire range, and they have a better app with sound customization features. However, the Beats can connect via USB-C, which gives them lower latency than a Bluetooth connection and lets you connect with gaming consoles with full mic and audio support.

Bang & Olufsen Beoplay H95 Wireless

The Bose QuietComfort Ultra Headphones Wireless are better overall headphones than the Bang & Olufsen Beoplay H95 Wireless. Both headphones have a lot of bass on tap, but the Bose also have a better ANC system that does a great job of tackling low-frequency sounds, like engine rumble. They're also more comfortable and have an immersive audio feature. That said, the B&O have a longer continuous battery life.

The Bose QuietComfort Ultra Headphones look very similar to the Bose QuietComfort Headphones Wireless and the Bose QuietComfort 45/QC45 Wireless. Overall, they look fairly minimalist, especially with the manufacturer's name modestly embossed on the center ear cup. The most noticeable difference is that the yoke is silver instead of completely black, and a similar design choice is made on the other color schemes. The 'White Smoke' model has silver yokes, while the 'Sandstone' model has gold yokes.

The control scheme is different than the Bose QuietComfort 45/QC45 Wireless with a touch-sensitive slider so that you can adjust the volume and only two buttons. All the controls are on the right ear cup, and there are chimes to let you know when you've powered the headphones on and off and when you've reached min or max volume. There are also voice prompts to indicate the battery level, ANC status, and pairing. There isn't feedback if you're pausing or skipping tracks, though. The volume slider is also a bit inconsistent, and you must use the tip of your finger to get the right volume increment. This slider also lets you access a shortcut command (which is settable in the companion app) by pressing and holding it in place.

Power button:

  • Single press: Turns the headphones on and off.

The carrying case is great. It's very similar in quality to other Bose products but is rounded. It's still very sturdy, though, and is made from plastic and faux leather. It has a zipper that's covered to protect it from damage and soft, molded padding to ensure you place them correctly within the case. There's even a pouch to store your cables when not in use.

Build Quality

The Bose QuietComfort Ultra Headphones have a great build quality. They're mostly made of plastic with aluminum and leather detailing, which makes them feel durable and sturdy. There's also a good amount of plush padding. That said, the folding hinge can wear down with time and lose its snappiness. Leather can also wear down with continual use.

Stability

These headphones are decently stable. They'll stay on your head if you jam to music at your desk or on the couch. However, they can shift around in place with head movements and can even fall off if you're vigorously moving your head. As a result, they're not the best choice if you want to use them during tough workouts.

The Bose QC Ultra Headphones have a bassy sound profile with a relatively flat mid-range. Their treble range is slightly veiled, but it's still relatively clear, if a bit uneven. Your audio is delivered with extra thump, while kick drums have a good amount of boom. Lead instruments like guitars and keys sound clear, while sibilants like the harmonics of cymbals come through as mostly detailed. The slight treble de-emphasis means they won't prematurely cause your ears to fatigue.

If you prefer a different sound, their companion app offers EQ presets, which retain the extra low-end. You can also fine-tune their sound to your liking a bit by using the custom equalizer. They also sound slightly different with less treble emphasis if you use them wired rather than wirelessly.

These headphones have Bose's CustomTune technology, which allows the headphones to automatically adjust their noise isolation and sound profile based on your personal listening capabilities. As a result, it's difficult to get consistent measurements as the headphones constantly adapt and retune their sound. That said, you'll still experience a drop in bass if you have thick hair or wear glasses.

The Bose QuietComfort Ultra Headphones' bass target compliance is excellent. The response is elevated from the low bass through mid bass for extra thump and rumble. The high bass adheres to our target tightly for a good amount of boom on kick drums. This can be pleasing if you're listening to especially bass-heavy mixes like Starboy by The Weeknd.

The treble's target compliance is superb. It lands close to our target response from the low-treble through mid-treble for a bright, detailed sound. It wavers slightly, but vocals remain articulate, and sibilants (like S and T) sound detailed. These elements may compete with the elevated bass, but you can adjust the equalizer for a different treble response.

The peaks and dips performance is very good. Aside from a few peaks, the headphones can control their sound profile quite well. There's a minor bump in the mid-bass, which adds a touch of extra thump to mixes. The treble range sees the most dips and peaks, though they're mostly not very large. It dips where the mid-range transitions to the low treble before a small peak causes vocals and instruments to sound harsh, while a dip weakens their detail. A series of small peaks in the mid-treble causes sibilants like cymbals to sound piercing.

These headphones have very good imaging. We've tested many Bose products, which are also very consistent, which indicates the manufacturer's quality control and ergonomics. That said, imaging varies across units. Our unit has mismatched group delay in the bass range. This results in very loose bass, so already thumpy and rumbly tracks like The Weeknd's Starboy miss out on their initial attack and sound off and uncontrolled. That said, our unit is still well-matched in amplitude, frequency, and phase response, which helps ensure a stable and even stereo image.

Like the Bose QuietComfort Ultra Earbuds, these headphones support Bose's Immersive Audio. This is a head-tracking feature that can make your audio feel more spacious and real-life. It doesn't utilize any surround content, though, and only uses regular audio content. There are two settings (other than off): 'Still', which virtually places the speakers in front of you and tracks your head to keep audio placed in relation to your original position, and 'Motion', which allows the virtual speakers to move as you move your head, always keeping them placed in front of you. That said, these headphones can't play surround content like Dolby Atmos as they have to downmix this content to stereo. That said, they use digital sound processing (DSP) to virtually create a wider stereo soundstage.

The Bose QuietComfort Ultra Headphones' weighted harmonic distortion performance is decent. There's a bump in both drivers at max volume throughout the mid range, but the overall amount of distortion is still quite low and very difficult to hear unless you're an astute audiophile. All frequencies otherwise fall within acceptable levels, which results in mostly clear and pure audio reproduction.

The Bose QuietComfort Ultra Headphones' full-range noise isolation performance is outstanding, which is on par for a brand built on noise cancelling (ANC) technology. Unlike the Bose QuietComfort 45/QC45 Wireless, they support Bose's CustomTune feature, so their ANC automatically adjusts to your hearing capabilities and surroundings. As a result, they can easily block out the low, bassy rumbles of bus and plane engines as well as mid-range noise like ambient chatter. They also reduce the high-pitched hum of AC units very well.

If you're looking for a bit more customization and control over your noise isolation performance, you can access ANC modes in the companion app, as well as adjust and set your own ANC presets. Although there's an ANC slider, it doesn't affect the strength of the ANC itself but the strength of talk-through (labeled as 'Aware' in the app) mode, which allows the headphones to let in your desired amount of ambient sound. Also, the headphones only have ANC or 'Aware' modes, which you can modify the strength of and adjust to your preference, but there's no normal mode without noise cancelling or transparency.

In response to user feedback of a high noise floor when ANC is enabled and volume set low, we retested the headphones but couldn't replicate the issue. However, noise sensitivity is a subjective experience.

Just like with our Noise Isolation - Full Range test, these headphones do an incredible job of blocking out ambient sound in more dynamic environments. Whether traveling by plane, hanging in a busy office, or walking down the street, the ANC system can reduce a significant amount of sound around you so that you can focus on your audio.

ANC Wind Noise

These headphones have a wind noise reduction feature called Wind Block. The manufacturer advertises that it mutes the ANC microphones located on the exterior of the ear cups to limit the ANC from picking up this sound and amplifying it. Overall, it helps tackle wind a little more efficiently than when this feature is disabled. When used, the ANC can reduce some bass to mid-range frequencies. This reduction is also better than headphones without a wind reduction feature like the Sony WH-1000XM5 Wireless.

That said, wind directly interacts with the ANC's microphones. The ANC system tries to cancel it out, even though this sound doesn't reach your ears, but, as a result, it causes loud and unwanted noise. Using the Wind Block feature could also impact ANC performance when wind is present.

The mic's recording quality is very good. Your voice sounds natural and clear, although a bit thin. Although Bose advertise these headphones to have a 'Self Voice' feature, which allows you to hear your own voice while on the phone (this is also known as sidetone), we couldn't get it to work. Our experience also appears to be a common one.

The Bose QC Ultra Headphones' battery performance is great. The manufacturer advertises them to last 24 hours continuously, but we measured 29 hours. That said, battery life varies on use, including your volume levels. Unfortunately, unlike other models like the Bose QuietComfort 45/QC45 Wireless, you can't use these headphones passively. You can use them wired, but the headphones must be on to work.

The Bose Music app is great; you can see a video of how it works here. You can access a graphic EQ and presets and Immersive Audio, a head-tracking feature for a more immersive experience. You can switch between different ANC modes and create ANC presets and immersion modes. While there's an ANC slider, it doesn't adjust the strength of the ANC but the talk-through strength, which is the amount of ambient sound the headphones let in. Additionally, you can adjust features like the auto-off timer, on-head detection, and Bluetooth source detection (if you want to connect the headphones to more than one device at a time).

The Bose QC Ultra Headphones come with a 1/8" TRS to 1/16" TRS cable that you can use for analog audio. However, like the Sonos Ace Wireless, you have to turn on the headphones to use this connection. There's also some latency when using this connection. While minor, the delay can be frustrating if you're gaming competitively or working on sync-sensitive content. The headphones perform an analog-to-digital conversion, amplifying the source and possibly adding any EQ customization onto the signal, which adds latency.

They also come with a USB-A to USB-C cable for recharging the headphones. You can't use it to passthrough audio, though.

These headphones have good Bluetooth connectivity. They support multi-device pairing, so you can stay connected with two devices, like a PC and smartphone, simultaneously. While they have high latency if you're using the default SBC codec, they also support aptX Adaptive, which automatically adjusts to your audio content. If you're listening to high-quality audio, it'll enter its High-Quality mode; however, expect a lot of latency. However, this codec can also shift into a low latency mode. If you're streaming videos, latency is significantly reduced, but it's still noticeable. That said, some devices compensate for latency.
