Sound Quality
The Bose QuietComfort Ultra delivers a sound profile that leans heavily towards bass. It offers robust sub-bass extension but the emphasis is more pronounced than the rest of the audio spectrum, creating a bass-rich experience. This approach follows the Harman target curve closely, though with a bit more intensity. Consequently, the mids can feel somewhat subdued due to the strong bass presence, yet they remain clear and detectable. The treble is well-balanced, falling between the bright profile of the QC45 and the overly smooth QC35ii.
In terms of technical performance, the QuietComfort Ultra aligns with typical consumer noise-canceling headphones in the market. It may not impress a dedicated audiophile with its dynamics or detail retrieval, but it serves its purpose effectively. The soundstage may seem more expansive compared to other noise-cancelers, mainly due to the emphasis on bass and the subdued mids, which create an impression of spaciousness akin to the Bose NC 700.
As a noise-canceling headphone, the sound is pleasant and unobtrusive. The only potential drawback for some listeners may be the heavy emphasis on bass, which can be adjusted using the Bose Connect app’s default bass reducer preset. This feature allows you to fine-tune the bass level with ease, catering to those who prefer a more balanced sound.
Personally, I’ve grown to enjoy a stronger bass response over the years, making these headphones ideal for commuting. When listening at my desk, I adjust the bass down by a couple of decibels to achieve a more balanced sound that suits my preference.
Additional Modes
In Aware mode, the QuietComfort Ultra allows ambient sound to mix with your audio, which can be useful in certain situations. Immersive mode enhances the soundstage, but it definitely affects sound quality and accuracy.
I find that the tonality and technical performance don’t really change much between modes so I’d recommend using the QC Ultra in its most suited mode, the ANC mode in order to get all the benefits from the headphones.
Comparison to other ANC Headphones
The QuietComfort Ultra stands out as my top choice among Bose’s headphone lineup due to its superior overall balance and cohesion. While I have a fondness for the QC35ii, the QC Ultra represents a significant improvement over its predecessor.
In contrast, the QC45’s brightness necessitates equalization, even though it boasts the most robust bass response. The Bose 700, on the other hand, suffers from a hollow-sounding midrange and an overly pronounced low and mid-treble. Given the option, I would lean towards the QC Ultra or the QC35ii, as they deliver a more satisfying listening experience without the need for equalization.
Sony’s XM5 headphones feature a V-shaped sound profile with pronounced bass similar to the QuietComfort Ultra, but with added emphasis on the treble. This balance appeals to some listeners, as the strong bass is balanced by the elevated treble, though this combination can lead to listener fatigue during extended use.
When compared to the AirPods Max, I prefer the overall sound balance of the latter. The AirPods Max delivers cleaner, punchier bass than most ANC headphones on the market, though its treble can occasionally seem shimmery and slightly artificial. Nonetheless, this emphasis doesn’t become as harsh as it can with the QC45 or the XM5.
Conclusion
If you’re looking for the best noise-canceling headphones focused on maximum noise isolation, the QuietComfort Ultra is an excellent choice. It competes closely with the Sony XM5, with slightly better performance in low and mid-frequency noise cancellation.
Sound-wise, it’s a toss-up between the QuietComfort Ultra, Sony XM5, and AirPods Max due to their respective apps’ EQ features. For me, the AirPods Max offers the most balanced sound, while the QuietComfort Ultra stands out for its top-notch comfort and ease of use.
Ultimately, your choice depends on your preferences and priorities. If you’ve been holding on to older Bose models, the QuietComfort Ultra is a worthy upgrade. For those seeking a premium noise-canceling headphone irrespective of brand, the QuietComfort Ultra offers a compelling option.
