Bose QuietComfort Ultra Headphones Review! The Ultimate Headphones That Transform Video Viewing and Commuting with Overwhelming Noise Cancellation and Immersion
“The ultimate silence and the thrill of being enveloped in sound.”
The Bose QuietComfort Ultra Headphones are not just any noise-canceling headphones. After using them, the hustle and bustle of trains, cafes, and offices vanished in an instant, as if a personal musical space had opened up around me... an experience that has made my daily life feel a little more luxurious.
In this review, I will thoroughly explore the appeal of the Bose QuietComfort Ultra Headphones that I personally experienced!
The Overwhelming Appeal of the Bose QuietComfort Ultra Headphones
Shut Out Surrounding Noise! World-Class Noise Cancellation

When you think of Bose, you think of noise cancellation. Their technical prowess is truly overwhelming. When I actually used them on my train commute, the sound of the train, announcements, and even the chatter of people around me became almost unnoticeable.
Both active and passive noise cancellation create a silent space that feels entirely your own, allowing you to focus incredibly well on watching videos or studying.
As if enveloped in sound! Bose's proprietary Immersive Audio

“Sound doesn't just come from your ears; it rains down from 360 degrees.” Bose's proprietary Immersive Audio (spatial audio) feature is truly shocking. I love movies and dramas, and when I watch them with these headphones, the realism makes it feel like dialogue and sound effects are racing around me.
With an immersive feeling like being in a movie theater, watching videos has become overwhelmingly more enjoyable. This is a feature I would wholeheartedly recommend not just to music lovers, but to fans of video content as well.
Above all, the fact that it can simulate spatial audio even for videos that don't support it is a compelling feature I feel is unique compared to other products. It's seriously the best.
Optimizing sound quality for your ears! CustomTune technology

Everyone's ear shape is different. Bose QuietComfort Ultra Headphones use CustomTune technology to automatically analyze your ear shape the moment you put them on. They optimize perfectly to the user's ears, adjusting any genre of music to the best possible sound quality.
I really want you to experience the feeling of having your own personal acoustic space. However, the analysis finishes in an instant, so it's a mystery what kind of analysis it's actually doing.
Three listening modes that can be switched according to the scene

You can switch between three modes with one touch: Quiet (maximum noise cancellation), Aware (external sound passthrough), and Immersion (spatial audio).
You can choose the optimal listening experience for every scene, such as commuting, working, or relaxing. I use Aware mode at home, Immersive for movies at home, and Quiet when I'm on the train commuting or in a slightly noisy cafe.
Lightweight & premium materials for a comfortable fit even over long periods

In addition to a lightweight design of about 250g, premium materials are used for the headband and ear pads. I actually used them for hours, and my ears and head didn't get sore; they were completely comfortable without the pressure typical of headphones.
The design is also sophisticated, and they are compact, making them easy to carry around. I can recommend these even to people who are concerned about the size of headphones.
Excellent usability! Packed with features like wear detection and multipoint connection

They are packed with features convenient for daily use, such as wear detection that automatically stops playback when you take the headphones off, multipoint connection that allows you to connect to a smartphone and PC at the same time, and intuitive touch and button controls.
It's to be expected at this price point, but they have definitely covered all the necessary features.
Clear call quality makes them suitable for online meetings as well

Equipped with a high-performance microphone system, they allow for clear calls even in noisy environments. Remote meetings and online calls are stress-free.
I actually used them for a company web meeting, and the quality is perfectly usable without any issues.
Battery peace of mind! Long-lasting design for up to 24 hours

You can enjoy up to 24 hours of continuous playback with Immersive Audio turned off, and up to 18 hours with it turned on. There is almost no need to worry about running out of battery even if you use them all day.
They also support quick charging, allowing for up to 2.5 hours of playback with just a 15-minute charge. Honestly, the battery performance is perfectly fine for me.
Pros and Cons of the Bose QuietComfort Ultra Headphones

Pros
Bose QuietComfort Ultra Headphones are packed with features that will satisfy music lovers, as well as movie and drama fans! I have summarized the pros I felt after actually using them.
Watching videos with Immersive Audio (spatial audio) is the best
Overwhelming noise cancellation performance ensures silence even on trains or in the office.
The experience of being 'wrapped in sound' through spatial audio sets them apart from conventional headphones. It truly makes watching videos fun!
Personalization via CustomTune allows anyone to enjoy the best sound quality.
Lightweight and comfortable fit for stress-free long-term listening. Recommended even for those who dislike pressure.
3-mode switching supports various uses such as ambient sound pass-through and focus.
High call quality, suitable for remote work and web conferencing.
Supports multipoint for simultaneous connection to multiple devices.
Detailed settings can be adjusted via ear cup touch controls or the app.
For those who want to achieve both "silence" and "sound immersion," this is truly an ideal device. I've listed various benefits, but above all, I am particularly drawn to the Bose-exclusive Immersive Audio (spatial audio) feature that turns any video or music into spatial audio.
Disadvantages

Bose QuietComfort Ultra Headphones have some points of concern, but you will likely feel they are worth more than that.
The price is high (around 60,000 yen). As a high-end model, it is not suitable for those who prioritize cost-performance.
Battery life is up to 24 hours, which is somewhat short for headphones.
Touch controls and button layout are not intuitive and are somewhat difficult to use until you get used to them.
Power must be on even when connected via wire; passive playback is not possible.
Honestly, the price was out of reach when they were released, but I bought them once they reached a price range I could afford. Even now, this is a high-end model that provides the "best sound experience." Honestly, they have become an item I cannot let go of.
Bose QuietComfort Ultra Headphones are recommended for these people!
For those wondering, "Are these right for me?", they are especially recommended for the following people!
People who seek high levels of silence in noisy environments like commuting, school, or cafes.
People who prioritize spatial audio and an immersive sound experience.
People who want to enjoy watching movies, dramas, and other videos to the fullest.
People looking for headphones that are comfortable even when worn for long periods.
People who dislike the size and pressure typical of headphones.
People who prioritize sound quality, features, and comfort over price.
Gadget lovers who want to take advantage of customization and app integration.
"I want to immerse myself more in music" or "I want to focus in a quiet environment." These headphones will surely upgrade your daily life by a notch.
Summary

Bose QuietComfort Ultra Headphones are top-class in every aspect: noise cancellation, sound quality, comfort, and functionality. After actually using them, I realized that this is a device that lets you easily experience the "thrill of sound" and the "luxury of silence" in every scene of your daily life.
It is a bit of a luxury investment, but it is well worth it. If you really want a great pair of headphones, please give them a try!
It truly is a product that improves your quality of life!
