QuietComfort Ultra

"The sound quality is good, it doesn’t feel quite as clear and completely lacks the detail the Technics and Sony have."

While some find the sound pleasant and bass-heavy, many users note a significant lack of detail and clarity compared to competitors, with some finding it muddy or flat.

"The Bose are more comfortable than the Sonys, hands down."

The Bose QC Ultra are overwhelmingly praised for their comfort, with users frequently stating they are the most comfortable headphones they have ever worn.

"Both headphones are rated at 30 hours of battery life, and I believe this to be accurate."

Battery life is generally considered adequate and competitive, meeting user expectations for daily use, though not class-leading.

"Build quality feels premium and durable compared to Sony."

The build quality is frequently described as premium, with users appreciating the materials and design, though some minor squeaking or coating issues are mentioned.

"In a quiet environment, the Bose provides clearer sound quality. However, in noisy environments, Sony does a great job with noise gating and blocking external noise."

Call quality is considered decent in quiet environments but is noted to be less impressive than competitors in noisy conditions, with voices sometimes sounding processed.

"Unfortunately the last update ruined the whole user experience for me completely."

Users report significant frustration with buggy software, unintuitive controls, and a lack of essential features like conversation mode, with recent updates further degrading the user experience.

"The sound quality of the Ultra Gen 2 is impressive, featuring a beautiful mix across frequencies and an expansive soundstage that surpasses most competitors."

The sound is generally described as good, with a pleasing bass and clear mids/highs, though some reviewers note it's not as refined or neutral as top competitors and may require EQ.

"These headphones are some of the most comfortable in the group. We were able to wear them for more than ten hours without needing a break."

Users consistently highlight the headphones' exceptional comfort, lightweight design, and plush padding, making them suitable for extended wear.

"They are so comfortable; those hours are going to whiz by, and we wish the battery life were longer, though it is longer than in prior generations."

Battery life is considered adequate for most users, offering around 24-30 hours, but it's noted as average and significantly reduced when using immersive audio features.

"And despite looking flimsier than some of their rivals, their build quality appears to stand the test of time; our sample of the original Ultra still look relatively new despite having been frequently used by our reviews team for two years."

The build quality is generally seen as good, with a smart, sleek, and durable design that holds up well over time, though some note it's not as premium as the highest-end rivals.

"Making calls is a lovely experience with the 2nd Gen. No matter how busy or chaotic the environment, voices remain front and center with a loud and clear presence."

Call quality is described as good to very good, with voices generally clear, though some users report occasional echo or distant-sounding voices on the other end.

"The Bose pair equally well with every operating system we tried, including Android and iOS. It had seamless multi-point connections between devices, making it a potential shoo-in for those who work across platforms with various connection needs."

The headphones offer solid features like multipoint connectivity, customizable EQ, and spatial audio, though the app is considered basic and some features like wireless charging (for earbuds) are missing.

"The QC Ultra's sound signature is much clearer than the Sony model."

Users describe the sound as clear, rich, and well-balanced, with a notable immersive audio mode that enhances the listening experience, though some note a lack of bass richness compared to competitors.

"These are the ONLY headphones I have ever owned that don't give me any top head pain after long term wear (1hr+)."

The headphones are frequently described as exceptionally comfortable, even for extended wear, with a lightweight design and soft earcups that do not cause pressure or heat.

"In fact, as far as battery life is concerned, I think that Bose has underestimated its headphones, because without the immersive mode, and staying at 60~65% maximum volume, I've actually gone up to around 30 hours."

While some users report exceeding the advertised battery life, others find it falls short, particularly when using features like immersive audio, leading to mixed satisfaction.

"As a Bose 700 owner I like that these have gone back a little more towards the quiet comfort build style"

The build quality is generally seen as solid and durable, with a design that is both foldable for portability and comfortable, reminiscent of older, well-regarded Bose models.

"The call quality on both ends of the call is TRAGIC, so much so that I had to send them back."

Call quality receives mixed reviews, with some users finding it clear and effective even in noisy environments, while others report significant issues with background noise and clarity for the person on the other end.

"Multipoint is amply correct, and the solid Bluetooth is certified in 5.3 (the latest available), which is much better in terms of wireless connection stability."

Features like immersive audio and multipoint connectivity are appreciated, but the lack of USB-C audio, limited EQ options, and occasional connectivity glitches detract from an otherwise strong feature set.
