Bose QuietComfort Ultra Headphones Review

The luxe design of the QuietComfort Ultra is apparent as soon as you open the box. High-end craftsmanship in subdued colorways feels sophisticated. The TriPort venting system expands the acoustic space, making music sound bigger, bolder, and deeply immersive.

Sound Quality

The QuietComfort Ultra earned one of the highest sound scores for its all-encompassing, full-bodied, and well-balanced audio. The bass is clearly amped up, but never sounds bloated. The clarity is superb and remarkably consistent across the entire range of volumes. If you like punch and drama in your listening experience, the Ultra is it.

When you slip on these headphones, they calibrate the sound to your unique ear shape, ensuring that every listener receives the best audio quality. Music across all genres is relayed with an exciting and cinematic tone, energizing every track.

The bass is powerful yet tight and crisp across hip-hop, R&B, and pop artists like Doja Cat, The Weeknd, and the Notorious B.I.G. We even uncovered new details, like the low, computer-like thrum at 1:55 in Taylor Swift's “Glitch” which had previously gone unnoticed. While fun and punchy, it's important to note that some audiophiles may find the bass too strong for their taste.

The mids are beautifully developed, with a vivid range of color and pristine clarity. We loved listening to the nuanced details in folk, soft rock, and soul tracks like “Just a Letter” by James Keelaghan, “Tired of Being Alone” by Al Green, and “Helpless Hoping” by Crosby, Stills, & Nash. While the lows are turned up, the mids seem to hold their own and maintain a distinct presence in the mix.

The highs are lovely and clean, but feel a bit more distant. High-hitting vocals and instruments never sounded harsh and maintained a rich character across pop, twangy western, and opera. The harmonica solo in Mike Stevens' “Amazing Grace” is a prime example. Even when there's a crescendo on a high note at 3:42, these headphones maintained their dynamic balance, allowing us to bliss out without ever wincing. However, sometimes, vocals sounded veiled behind the lower frequencies, making them feel less developed than the other ranges. Still, they're incredibly pleasing.

Soundstage

We also consider the soundstage and how spacious the sound feels. The Ultra's have one of the best soundstages, making the music feel like a rich cinematic listening experience. Individual instruments and vocal lines are separated in space and relayed with outstanding clarity across a three-dimensional landscape. It's ever slightly more compressed than other top competitors, but it's still one of the most expansive soundscapes we have experienced.

Frequency Response

We backed our expert opinions with a frequency response analysis to visualize exactly how the Ultra is tuned.

Like our Target Response Curve, the Ultra brings more emphasis to the lows and highs, adding extra flair to exaggerate the performance. The lows get the most boost, bringing on that head-bobbing energy that makes you want to groove.

Comfort and Fit

When it comes to comfort, the QuietComfort Ultra reigns supreme. The luxe materials are top-of-the-line, providing 10 solid hours of blissful wear time, even with glasses on.

The spacious earcups and adjustable headband feature plush cushions wrapped in a breathable, buttery-soft, faux leather material that feels luxurious and high-end. Combined with the headphone's gentle clamping force and lightweight design, make the Bose Ultra our favorite for long listening sessions.

Noise Cancellation

The noise canceling on the Ultras is one of the best. It places you on an island of peaceful tranquility, no matter the surroundings. The transparency mode is equally stunning, relaying ambient sounds so naturally that it felt like we weren't wearing headphones.

The Ultra blocks out an astounding 20-40 decibels of noise across the entire frequency spectrum, reducing office chatter to blissful silence. People had to tap us to get our attention. Even roaring airplane engines and kitchen blenders were diminished to a whisper. While most headphones struggle to block out common everyday mid-range sounds, Bose excels.

In a bustling cafe, they do an incredible job of insulating the user from monotonous low-frequency hums and background chatter. A sudden, high-pitch dish clash at 0:16 comes through slightly louder but is barely audible.

While we love Bose's ANC and aware modes, unlike most competitors, you must choose either noise-canceling or transparency mode; you can't go without one or the other. Despite all the ANC customization options in the Bose app, there isn't an option to turn off the ANC without simultaneously turning on Aware mode. It's an odd choice for such an expensive headphone and may be a deal-breaker for those who are sensitive to full-powered ANC.

Ease of Use

The Ultra are one of the most user-friendly. The controls are intuitive and reliable, and the app has plenty of useful features that are easy to navigate.

We only wish the sound were a bit more customizable, which is why it didn't score higher.

Controls

The controls on the Ultras are one of our favorites because they are reliable and intuitive. A standard Bluetooth/Power button powers the headphones, connects to your phone, or cycles between two connected devices. The Multifunction button controls media playback, phone call actions, and noise-canceling modes. A touch strip on the back of the earcup lets you adjust the volume. Normally, we find touch controls finicky, but this one worked well.

In addition to hand-activated controls, the Ultra also supports hands-free head detection, which automatically pauses or plays the audio when it senses if you are wearing them. For us, this feature is a must on premium headphones, ensuring you never lose a second of your favorite song or podcast.

Customization

The most important features in an app are the sound equalizer (EQ) and presets. They should allow you to fine-tune the sound, but in Bose's case, the adjustments feel limited. The three-point EQ slider wasn't very sensitive to changes, and there are only four presets. If you like to tinker with the ranges, you might find the limited customizations disappointing.

When used in conjunction with a compatible audio file and device, Bose's Immersive Audio feature adds more dimensionality to your listening experience. It's basically the headphone equivalent of surround sound. The headphones can also track the motions of your head and move the imaginary field of speakers relative to its position. Some find this disorienting, but this experience is fun and exciting for others.

Android users with compatible devices that support Snapdragon Sound can unlock the Ultra's aptX Bluetooth codec for lossless audio, which promises better audio clarity.

Battery

Battery life could be a purchasing factor if you travel regularly or don't enjoy frequent plug-ins. The Ultra has one of the shortest battery lives in our lineup, lasting about 24 hours. It's likely enough to get you through, but it falls short next to competitors that push 50-70 hours.

The Ultra does support fast charging, so 15 minutes of plug-in time will give you a couple of hours of play. For a full charge, you'll need to keep it plugged in for two to three hours. You can use the headphones while charging.

Call Quality

The QuietComfort Ultra call quality is about average. The voice isolation technology does a decent job of removing distracting background sounds in noisy public spaces, but the baseline voice quality itself isn't the cleanest. You might find the Bose unimpressive if you rely on your headphones for Zoom meetings or calls.

The Bose handled phone calls from our simulated subway better than most, but fell short of the best. Loudspeaker announcements and whirring trains are clearly audible, but our callers' voices are at least pushed to the forefront without significant distortion.

Similarly, background voices, mouse clicks, and keyboards are reduced in a noisy shared office space, but are audible to the person on the other end. Plus, the caller's voice sounds slightly robotic, which could be distracting.

When calling from a quiet space, the Ultra's grainy voice quality became more apparent. The caller's voice sounded dampened, making it hard to hear. Sometimes, words randomly cut out, which was frustrating. We'd rather use a cell phone than the Bose for phone calls.

Should You Buy the Bose QuietComfort Ultra?

It's really hard to go wrong with the QuietComfort Ultra. It's an investment, but in return, you'll get a wonderfully rich and immersive sound, world-class noise cancellation, and unparalleled comfort. At this level of premier quality, you only need to ask yourself two questions: 1) Do you enjoy a powerful bass? 2) Are you okay with mediocre call quality? If the answer is yes, and you can afford the price, we think you'll love the Ultra for years to come.
